The pandemic has urged countries around the globe to mobilize financing to support the recovery. This is even more relevant in Central America, where the policy response to cushion the pandemic’s economic and social impact has accentuated pre-existing debt vulnerabilities. This paper documents the potential for local currency bond markets to diversify and expand financing for the recovery, lowering bond yields, funding volatility, and exposure to global shocks. The paper further identifies priority actions, both national and regional, to support market development.

Abstract

The pandemic has urged countries around the globe to mobilize financing to support the recovery. This is even more relevant in Central America, where the policy response to cushion the pandemic’s economic and social impact has accentuated pre-existing debt vulnerabilities. This paper documents the potential for local currency bond markets to diversify and expand financing for the recovery, lowering bond yields, funding volatility, and exposure to global shocks. The paper further identifies priority actions, both national and regional, to support market development.

I. Introduction1

Although most Central American2 countries entered the COVID-19 crisis with moderate debt levels in global comparison, the pandemic is weighing on the region’s fiscal balance sheets. Fiscal deficits have widened due to the need for higher healthcare spending and social transfers to respond to the COVID emergency and help protect the most affected, lower tax revenues, and, in some fiscally vulnerable countries, higher financing costs. Gross financing needs have increased markedly as a result, prompting countries in the region to adopt hybrid financing strategies spanning upscaled loans from multilateral financial institutions and bilateral creditors alongside Eurobond placements. While reliance on international capital markets can be a cost-effective way to finance the recovery, further development of the local currency bond markets (LCBM)—a reform ambition that has been on the CADR’s agenda over the past two decades (Hemant et al., 2007)—can limit countries’ exposure to shifts in investors’ sentiment, especially in presence of rising debt ratios.

Domestic sovereign debt markets have been found to provide resilience to shocks in times of financial turbulence and, by expanding financing opportunities and diversifying risk-return preferences, to lift long-term growth (IMF and WB 2021). In CADR, currently underdeveloped LCBM limit the amount and maturity of local funding available to governments, while increasing the financing costs, spreads volatility in the face of global liquidity shocks, and the rollover and currency risks to sovereigns. Furthermore, issuance fragmentation and the absence of a liquid benchmark yield curve prevent long-term funding for borrowers and proper risk management for institutional investors.

To identify key reforms for the efficient functioning of LCBM in CADR, this study first discusses the stage of development of domestic sovereign debt markets primarily based on a novel approach (IMF and WB, 2021). The proposed framework evaluates the legal foundations, market infrastructure, investor base, and the money, primary and secondary markets underlying the LCBM. The resulting assessment indicates that (i) most countries in the region lack a medium-term management strategy (MTDS); (ii) the financial market infrastructure hinders transactions in the money, primary, and secondary markets, which remain fragmented and shallow, preventing the formation of a reference yield curve; and (iii) investor bases remain primarily concentrated on few large banks and/or public institutions with scant participation in secondary markets.

Against this backdrop, this paper documents empirically the potential for LCBM development in the region to lower domestic bonds yields, reduce sensitivity to global shocks, and diversify public sector funding. To this aim, we follow Jaramillo and Weber (2012, 2013) and GFSR (2014) and estimate panel regressions based on a unique monthly dataset over 2007–19 for emerging and CADR countries. The focus is on estimating the nexus between LCBM development indicators and domestic bond yields, controlling for country-specific and common external conditions. Our findings suggest that further financial deepening through a larger and/or more diversified investor base, and greater bond liquidity, can materially lower yields and exposure to global shocks both in the whole sample and in the CADR-only sample.

Improving LCBM development in virtually all CADR involve a few critical steps including (i) developing a MTDS; (ii) enhancing the coordination of debt management and monetary policy with regards to primary market issuance; (iii) expanding the use of benchmark securities to foster the creation of a reference yield curve; (iv) promoting a tax framework conducive to the holding and trading of securities; (v) improving the custodian and settlement infrastructure; and (vi) expanding the investor base to long-term institutional investors. We also provide pragmatic advice on policy priorities and sequencing as informed by successful experiences of LCBM development in, e.g., some frontier economies.

The rest of the paper is structured as follows. Section II offers an overview of the current debt challenges facing CADR. Section III provides an overview of the benefits from LCBM development. Section IV discusses the status of LCBM development in the region. Section V investigates the link between LCBM development, domestic bond yields, and countries’ resilience to global shocks. Section VI concludes and offers policy recommendations.

II. Financing Conditions in Central America During the Pandemic

Most CADR countries entered the pandemic crisis with moderate debt burdens but weak debt affordability in global comparison. At about 60 percent of GDP, the region’s average debt-to-GDP ratio fared better than in other emerging market (EME) and developing economies. However, government debt burdens were already in an upward trend pre-COVID and government interest payments relative to GDP were among the highest in the world3. In some countries, low revenue bases also implied a high debt, and debt service, ratio to revenues. Within the region, Costa Rica, the Dominican Republic and El Salvador exhibited the highest debt and interest burdens.

The shock from the COVID crisis and the necessary responses to save lives and safeguard livelihoods materially increased government deficits and debt burdens.

  • Deficit dynamics. The region’s average deficit-to-GDP ratio increased by 4 percentage points. Fiscal deficits widened across the region due to higher health-related spending and social transfers, and lower tax revenues. Looking ahead, the expected gradual recovery of tax collections, and higher financing costs in fiscally vulnerable countries, is likely to put pressure on deficits.

  • Debt dynamics. The region’s average debt-to-GDP ratio increased by 13 percentage points. Higher interest rate-growth differentials (rg) dominated debt dynamics (over higher primary deficits) in most countries, notably Panama, El Salvador, and Costa Rica. Amidst tighter financial conditions, debt ratios are expected to remain elevated even as fiscal deficits stabilize, leaving less fiscal space than before the pandemic.

  • Immediate financing sources. In response to the sharp increase in gross financing needs, countries in the region adopted hybrid financing strategies. Larger issuances in domestic markets were the first and immediate response. IFIs emergency financing supplemented budgetary liquidity. Additionally, the Dominican Republic, Panama, Guatemala and Honduras tapped into international markets, securing hard currency long-term funding at terms at least as favorable as those pre-COVID. El Salvador was also able to issue Eurobonds albeit at substantially higher yields.

Countries’ funding strategies face important challenges ahead. Some countries, such as El Salvador, have faced tighter financial conditions since the start of pandemic, both in international (267 basis points increase in EMBI spreads) and local (307 basis points increase in rates) debt markets4. For most sovereigns in the region, reliance on international capital markets can be a cost-effective way to finance for the recovery but can also expose countries to higher spreads volatility and FX risks, especially in presence of rising debt ratios. Against this backdrop, enhancing local currency bond markets could lower borrowing costs and exposure to global shocks.

III. Benefits from Further Development of LCBM in CADR

This section draws on IMF and WB (2021) and discusses the benefits arising from the development of local debt markets, with references to the typical six major building blocks of the LCBMs: money market, primary market, secondary market, investor base, financial market infrastructure (FMI), and the legal and regulatory framework.

An efficient money market facilitates the implementation of monetary policy, strengthens monetary policy transmission and provides a foundation for the maturity extension of government financing.5 Money markets are essential for the short-term financing and inventory management of market makers in government securities, as well as the liquidity management operations of commercial banks. In addition, they help create broader products such as floating rate instruments and hedging tools. Derivatives such as interest rate swaps can in turn facilitate the development of capital markets.

The domestic primary government bond market lays LCBMs’ foundations. It allows the debt manager to implement a debt management strategy and to establish a relationship with market participants. Sound primary market practices involve a transparent formulation and publication of a MTDS, market-based issuance mechanisms and pricing, the publication of auction calendars, and flexible use cash management practices. The primary market also provides a regular opportunity for two-way communications between the issuer and market participants.

A well-functioning secondary market provides a cost-efficient, secure platform for market participants to trade securities in a fair and transparent manner. The market structure should involve enough intermediaries that trade government securities in standard amounts and pricing, and during agreed times. This in turn provides wholesale investors with avenues to buy and sell their securities at short notice and at reasonable cost. Efficient secondary markets provide liquidity for government securities facilitating term transformation, thus allowing investors to hold asset maturities that are longer than for their liabilities. The secondary market also provides a pricing reference to the sovereign for primary issuance. A mature stage of LCBM development typically features sustained secondary market activity across the yield curve during normal times.

A deep and diversified investor base strengthens the resilience of the market in times of market stress by securing demand for government securities. The development of an investor base with diverse maturity and risk-return preferences, as is the case of institutional investors, allows the government to spread risk in its debt portfolio and helps to extend the yield curve. While the size of the financial sector largely defines the absorption capacity of government bonds, the structure of the financial sector can have a significant impact on market liquidity.

An efficient FMI facilitates the smooth flow and settlement of transactions in the money, primary and secondary markets, strengthens investor confidence, and stimulates the pace of market expansion. The state of development and functioning of the custodial and settlement infrastructure is a major direct determinant of systemic risk. Absent a sound securities settlement infrastructure, a market may be exposed to considerable systemic risks as the failure of one party to a large transaction may lead to a series of subsequent defaults.

The legal and regulatory framework affects the structure, functioning, and development of government securities markets. Legislation and other legal instruments, such as a fiscal agency agreement between the government and the central bank, provide for the ability of the sovereign and other government entities to borrow and to act in the markets, as well as the role of the central bank as a government agent. The legal and regulatory framework also shapes the organization of the primary and secondary markets and the roles of market participants.

IV. Status of LCBM Development in CADR

To assess the status of market development in CADR countries, we use the LCBM framework (IMF and WB, 2021; Annex I) to analyze sovereign debt markets in terms of their depth, liquidity, diversity and resilience. The framework covers the six building blocks already presented in the previous section and presents key findings and commonalities for the CADR region. Annex II provides detailed information on the status of LCBM development in each of the countries.

Legal and Regulatory Framework

The legal and regulatory framework should pursue fair, efficient, and transparent government securities’ markets. While many countries in CADR have reinforced their monetary policy frameworks, their securities’ markets and debt management legal foundations can be made more flexible by (i) enabling debt management authorities to define issuances strategies based on market conditions; (ii) preventing differential tax treatments that discourage market development for government securities; and (iii) reducing the mandatory, costly trading through intermediaries or the stock exchanges.

In many CADR countries, the legal framework should provide more flexibility to issue and manage debt. While debt management authorities are clearly defined in the region (Crédito Público), their ability to manage debt and undertake liability management operations that promote market development is often constrained by law. For instance, the budget law in Guatemala establishes the exact amount that can be raised domestically or externally during a particular fiscal year, hindering flexibility in adapting issuance to market conditions, prefunding, or building cash buffers. In both Guatemala and Honduras, the government lacks the legal framework to enable liability management operations. El Salvador’s Constitution establishes the legal framework for public debt management, mandating Congress’ approval of the budget and its financing, and all associated debt operations (rollover, LMOs, external loans, and Eurobond issuances).

The tax framework in many CADR countries has been biased against some investment instruments and entails unnecessary transactions costs or hindrances. In Costa Rica, the tax system has discriminated between types of instruments and investors. In Honduras, double taxation on mutual funds (on the assets held, and on the fund returns) inhibits the diversification of the investor base and the development of this industry. In Nicaragua, treasury bills and bonds were subject to withholding taxes, unlike repos that paid taxes on annual statements. Trading in the secondary market is discouraged by a withholding tax levied on the coupon (with no pro-rata for the period in which the investor effectively held the bond).

Trading continues to be costly in most countries in the region. Mandatory trading through intermediaries or the stock exchanges raises costs and inhibits market participation. In Honduras, investors trading government bonds in the secondary market must pay a transaction fee of 10 basis points. Mandatory trading through the stock exchange in Nicaragua and El Salvador restrains over-the-counter transactions.

Market Infrastructure

An efficient infrastructure facilitates the smooth flow and settlement of transactions in the money, primary and secondary markets, and strengthens investors’ confidence. While the existing market infrastructure is broadly fit for the level of activity currently present in CADR, some elements affect investors’ confidence and disincentivize trading in the money, primary and secondary markets. At the country level, progress has been uneven.

In some CADR countries, the fragmentation of central securities depositories (CSD) hinders market trading. Guatemala has been issuing securities in physical format until recently and the outstanding stock still remains fragmented into dematerialized and physical securities. The central bank keeps custody of dematerialized securities, while the stock exchange (CVN), alongside investors’ own vaults, keep custody of physical securities, overall resulting in shallow trading and settlement.

In El Salvador, the custody and settlement are integrated in the Central Securities Depository (CEDEVAL), which provides gross settlement, clearing, and custody of all those listed public and private domestic and international securities. Though still nascent, the stock market of El Salvador (BVES) has recently integrated with the stock market of Panama (BVP) to offer cross border settlement and custody. Despite such integration progress, foreign investors are not allowed to hold domestic securities in international custodians but are expected to use CEDEVAL, which disincentivizes external demand. Similarly, in Costa Rica the presence of foreign investors is hindered by limited and expensive custodian services.

Investor Base

A deep and diversified investor base ensures demand for government securities, strengthening the resilience of the market in times of market stress. The investor base in CADR is still relatively shallow. The banking sector features high concentration levels while public pension funds tend to be the largest, though not particularly active, market players. The lack of diversification is a vulnerability that weakens the stability of budgetary funding, especially in periods of stress. While the participation of private institutional investors (pension funds, insurance companies, and investment funds) remains generally low, some countries have made strides into developing private pension funds, diversifying risk-return preferences, and lengthening debt maturity.

Overall, foreign investors participation remains limited although some countries have structured (Costa Rica, Dominican Republic) or are working toward structuring (Honduras) Global Depository Notes (GDN) in an effort to diversify the investor base and stimulate foreign interest in their local currency bond market.

While still shallow, many countries in the region have made progress to diversify their investor base, either by promoting the development private pension funds through the AFPs or by tapping the retail sector. A recent survey conducted in 2019 revealed the authorities’ preference for expanding their investor base with foreign and retail investors, with a focus on expanding short-term funding to the government. Over the medium-term, there is scope for balancing the mix of investors given shortcomings associated with biased portfolios. 6

Despite trade integration, geographical proximity, common languages, and the presence of several regional financial groups, the integration of CADR public debt markets remains incomplete, further contributing to the lack of diversification of the investor base. This partly owes to the prevalence of different currencies and exchange rate regimes across the region, as well as substantially different debt burdens and sovereign ratings across countries. Thus, local currency bonds issued by each sovereign remain securities with very different risk characteristics. Another layer of complexity is added by prudential requirements that cannot be easily harmonized given the large differences in sovereign credit ratings. As such, banks face higher capital adequacy requirements on foreign than domestic government securities, which traditionally carry zero risk weighting.

Money Markets

A reliable short-term yield curve and active repo market provides the foundations for the issuance of long-term securities and the development of the secondary market. Despite efforts to modernize monetary policy operations and improve the functioning of short-term securities and repo markets, intermediation in the money market remains a challenge in CADR. Low trading volumes and discontinuous operations prevent liquidity risk management on long-term government securities, thereby lowering investors’ demand. This primarily owes to:

  • Structural excess liquidity. Excess liquidity often places investors on the same side of the market and hampers the growth of interbank trading volumes. This liquidity surplus mainly reflects commercial banks’ precautionary behavior, inadequate cost-efficient liquidity provision and, in some cases, persistent remittance inflows.

  • Dual Sovereign Issuers. The simultaneous, and often competing, issuance by the sovereign and the central bank, as well as heavy reliance on central bank securities for monetary policy operations (left chart) result into market fragmentation and hinder the formation of a liquid yield curve. This practice is partly due to a legacy of fragilities in their balance sheets and/or a framework preventing central banks from holding sufficient government instruments. The manifold instruments outstanding in the market is detrimental to establishing benchmarks and can potentially reduce the trading of government securities.

In addition to the elements mentioned above, country authorities also identify the relatively small size of their financial market and the elevated concentration of the banking sector as key elements deterring the development of money markets. While CADR countries face broadly common challenges, the status of development of each country is quite heterogenous (Annex II).

Primary Markets

Developed primary markets are characterized by a large share of marketable domestic debt and well-defined yield curves. The CADR region has made significant progress in the development of primary markets over the last two decades, especially through the implementation of the Debt Market Harmonization program. This region-wide initiative has enabled the adoption of common market conventions, standardized securities for new issuances, and delivered capacity development for debt managers. Nonetheless, there is room to further improve primary debt issuance, especially in enhancing (i) the transparency and accountability of debt management, and (ii) market-based issuances mechanisms and pricing.

The adoption of a MTDS signals a comprehensive and predictable approach to debt management, fostering market participation. Ongoing MTDS’ across the region are providing increasing guidance to investors. For example, Honduras’ 2020–23 MTDS sets out the general lines of central government domestic and foreign debt and promotes the development of the LCBM through market-based mechanisms. The Dominican Republic couches the government’s annual borrowing plan (ABP) into the MTDS. Costa Rica is modernizing its debt management practices, including a revamped MTDS with annual borrowing plans and quarterly issuance calendars embedded into the medium-term strategy. By contrast, Guatemala and El Salvador still lack a published MTDS.

uA001fig12
Sources: IMF and WB staff, based on Survey on Challenges for LCBM Development, 2019. Note: closer to the edge means the factor represents a greater challenge.

There is ample room in CADR to enhance market-based issuance mechanisms and pricing. A recent survey conducted in 2019 points to risks of market collusion in many countries, with issuers pointing to insufficient market competition and costly government debt amidst a shallow investor base and investors’ market power. This may explain that auction prices are at times set by the issuer rather than cleared at market prices.

Securities’ fragmentation remains elevated, resulting in a large share of individual negotiable and non-negotiable outstanding instruments, and hampering the liquidity in secondary markets. Key obstacles to the issuance of benchmark securities include an inadequate market infrastructure and practical obstacles to execute liability management operations.

Secondary Markets

The secondary market provides liquidity for government securities facilitating term transformation. Despite rising liquidity in recent years, secondary market activity in the CADR region remains shallow. Turnover ratios, defined as the share of secondary market trading in total debt stock, remain low in most countries. Public debt securities account for most of the market trading throughout CADR amidst underdeveloped corporate securities.

This results in relatively illiquid medium- and long-term yield curves, as public securities are predominantly traded on the money market. The associated opacity in the pricing of government bonds deters market trading, which is further affected by high transaction costs—brokerage and exchange fees—charged by local securities exchanges.

From CADR debt managers’ perspective, the main bottlenecks for developing secondary markets are the lack of benchmark bonds and the limited number/participation of institutional investors7. Both dimensions impede the deepening of yield curves and lessen liquidity in the government securities market.

V. Domestic Sovereign Bond Yields in CADR: The Role of LCBM Development

This section investigates the macroeconomic benefits associated with the process of developing LCBMs in CADR, arising primarily from a reduction in sovereigns’ financing costs. Despite the wealth of studies on sovereign foreign currency spreads, there is scarce empirical evidence that focuses on sovereign domestic currency bonds, especially for the CADR region.

Jaramillo and Weber (2012, 2013) provide evidence of the link between domestic bond yields in emerging economies and global risk appetite and liquidity. They also find that country-specific fundamentals, notably fiscal soundness, financial sector openness, and the current account balance, are relevant to amplify/diminish exposures to external factors. Mayijima et al. (2012) find that the development of a deep and liquid local currency bond market is key to mitigating risks associated with currency and maturity mismatches. In addition, GFSR (2014) finds that a set of indicators of local financial market development affects the sensitivity of domestic bond yields to external factors.

The remaining of this section explores the nexus between further LCBM development, domestic bond yields, and countries’ resilience to global financial shocks. To this aim, we estimate a panel regression model relating country-level local currency sovereign bond yields to indicators of financial depth, investor base diversification, and bond market liquidity. In our empirical strategy, we control for global financial conditions and domestic macroeconomic fundamentals.

A. Dataset and Methodological Approach

The empirical analysis uses a dataset of monthly observations (January 2007 to December 2019) for the 6 CADR economies and 6 benchmark emerging market economies (Mexico, Peru, Malaysia, Thailand, Hungary, Turkey). The dataset includes long-term (typically 10-year or relevant benchmark) local currency bond yields8 and one-year ahead market expectations for domestic conditions (annual inflation, real GDP growth, the fiscal balance-to-GDP ratio, and the current account-to-GDP ratio).9 We also include indicators of short-term domestic rates10 and of the stock of domestic bonds to control for financing conditions at the short-end of the yield curve and for possible fiscal sustainability risk premia. To capture external conditions, we include the 10-year U.S. Treasury bond interest rate as proxies for global liquidity, and the CBOE volatility index (VIX) as a proxy for global risk appetite.

The novelty of this empirical approach lies in the country-specific indicators of LCBM development, namely the depth of the financial market (financial system assets as share of GDP), the liquidity of the secondary bond market (monthly volume traded as share of the stock of domestic bonds, turnover ratio), and the diversification of the investor base (non-bank investor as share of the total investor base). As this dataset was compiled from each country’s central bank, ministry of finance, and/or stock exchange market, as appropriate, the availability and accessibility of monthly information was key in determining the sample of emerging market economies included.

Following previous empirical analyses on domestic bond yields for advanced and emerging economies, we estimate a static fixed-effects panel data model as follows:

ri,t=αi+Σk=1Kβ1,kGlobalk,t+Σp=1Pβ2,kMacrop,i,t+Σm=1Mβ3,mLCBMm,i,t+εit,

where ri,t is the nominal yield on the long-term domestic bond for country i. The model includes country-level fixed effects αt to account for time-invariant heterogeneity. The specification controls for K number of common external factors (Globalk,t) and P number of macroeconomic variables for each country i (Macrop,i,t). The model further controls for M number of development indicators for each country’s local currency bond market (LCBMm,i,t), including through interaction effects.

Finally, panel unit root tests (Im-Pesaran-Shin) were performed to rule out non-stationarity problems (see Annex III). Our estimations rely on Driscoll and Kraay standard errors, which are robust to cross-sectional and temporal dependence11.

B. Results

Our results (Table 1) show that domestic macroeconomic conditions are important determinants of bond yields. Domestic short-term interest rates are found to have a positive and significant effect on the term structure, at around 57 basis points for each 100 basis points increase in short-term rates. This result is consistent with previous studies, in similar settings, that suggest a response range from 45 to 89 basis points for the impact of short-term rates. An increase in the expected fiscal deficit of 1 percent of GDP raises on average nominal bond yields by about 14 basis points. This is slightly lower than findings of the literature for advanced economies (of about 25 basis points, see Laubach, 2009) and for emerging markets (ranging from 27 to 38 basis points, see Jaramillo and Weber, 2013).

Economic growth proved significant, reducing domestic bond yields by 15 basis point for each 1 percentage point increase in growth rate, in line with findings by Miyajima and others (2012) for a sample of 11 emerging economies. As stronger growth is associated with improved investment perspectives and lower fiscal vulnerabilities, it could be associated with an overall reduction in a country risk premium and a compression of domestic yields12. Similarly, we found that an improved current account balance could lower domestic yields, via a stronger external position and lower risk premium, although this result was not statistically significant.

We find that external conditions have positive effects on domestic financing costs, although their contribution to the yields is much lower than for domestic factors. A tightening in global liquidity conditions, captured by a 100 basis points increase in the U.S. Treasury bond yields, translates into higher domestic yields by about 8 basis points. As in Jaramillo and Weber (2012), global liquidity conditions in our sample are not found to be significant. Global risk conditions are found significant, with a 10-point increase in the VIX associated to a 40 basis points increase in domestic yields. The sign and magnitude for the VIX coefficient are consistent with Miyajima and others (2012).

Indicators of development of the domestic bond market proved significant under several specifications, especially when allowed to interact with global risk appetite (Table 1). To illustrate our findings, we compared the responses of domestic bond yields when faced with a deterioration of global risk sentiment, contingent on country-specific levels of LCBM development (text chart below). The effect of a 10-point increase in the VIX on bond yields for those economies with the largest 75th percentile ratio for non-bank investors base is 10 basis points lower than those with the lowest 25th percentile, underscoring the potential benefits of further diversifying investor bases.

In an alternative specification, we find that the effect of a 10-point increase in the VIX on bond yields for those economies with the largest 75th percentile ratio for the volume traded in the secondary market (as a share of domestic public debt stock) is 25 basis points smaller than those with the lowest 25th percentile ratio, pointing to the benefits of increasing bond market liquidity.

When allowing for cross-section specific coefficients in our panel, we find that estimated responses across country groups are quite heterogeneous, with European EMs being more sensitive to external volatility than EMs in LAC and Asia, as found in Jaramillo and Weber (2013). In our sample we also find a similar result for country groups sensitivity to external liquidity, with larger and significant impacts for European EMs. These results seem closely correlated with the degree of financial openness (as per the commonly used Chinn-Ito index) of each country group, except for CADR.

A closer look into CADR’s characteristics reveals substantial heterogeneity across countries that gets masked when aggregating. As a robustness check, CADR financial openness is also measured by the size of BOP portfolio investment flows as share of GDP. In assessing CADR exposure to external volatility, two groups clearly emerge: (i) higher-exposure countries featuring relatively high financial openness, comprising Costa Rica, the Dominican Republic and Guatemala; and (ii) lower-exposure countries featuring relatively low financial openness and larger concessional financing, comprising Nicaragua, Honduras, and El Salvador. As expected, bond yields in CADR countries with higher exposure to global risk conditions proved more sensitive to VIX fluctuations.

CADR: Financial Openness and Volatility Exposure

In view of these findings, we next confined our sample to CADR and replicated the empirical approach. Considering some CADR intrinsic characteristics we performed a few minor adjustments to our dataset, specifically we included the stock of local currency bond to capture possible fiscal sustainability risk premia and we considered excess reserve balances as one of the LCBM development indicators. Holding balances above the required reserve levels has been a common practice in some CADR countries, mainly reflecting the lack of proper interbank market development. Maintaining large non–interest bearing balances at the central bank could be expected to increase, ceteris paribus, the average interest rate charged by banks on remaining assets.

Our findings highlight that local macroeconomic conditions are key determinants of CADR domestic bond yields. Short-term interest rates, used as a proxy of the monetary policy stance, proved to be the main determinant, implying a 48-basis points response in yields, on average, when increased in 100 basis points. The fact that in most CADR countries central banks securities represent an alternative investment for buyers, renders CB rates as benchmarks. A widening of the expected fiscal deficit in 1 percent of GDP raises on average nominal bond yields by about 23 basis points, while economic growth proved significant, reducing domestic bond yields by 40 basis points for each 1 percentage point increase in the growth rate. In addition, the level of domestic debt also proved to be a significant factor for CADR, increasing bond yields in 8 basis points for each percentage point increase in the domestic debt to GDP ratio. Our estimates for the impacts of fiscal deficits and debt ratios are consistent with the findings of Jaramillo and Weber (2013) and Baldacci and Kumar (2010). Expectations on the current account balance and inflation were not found statistically significant for the region.

Percentile data are taken from the CADR monthly sample from 2007 to 2019.

Although external conditions have positive effects on CADR domestic financing costs, their impact is lower than in the full sample considering benchmark EMs. While global risk conditions were found to be statistically significant, global liquidity conditions were not.

Our results for the CADR region confirm that financial deepening and the proper functioning of local debt markets (bond liquidity) are associated with lower yields and sensitivity to global shocks. In addition, compared to the results for the whole sample, the indicator of financial system depth gained statistical significance in CADR13. On average, an increase in (i) financial depth of 10 percent of GDP reduces bond yields by 80 basis points; (ii) the volume traded in the secondary market of 10 percent of the stock of domestic public debt reduces bond yields by 40 basis points; and (iii) the non-bank participation of 10 percent of the total investor base reduces bond yields by 20 basis points. On the contrary, an increase in banks’ excess reserve balances of 1 percent of total deposits raises the financing cost by 8 basis points. We also find that further LCBM development can mitigate the impact of an episode of global volatility. Greater financial market deepening and secondary market liquidity could respectively save up to 47 and 10 basis points in domestic bond yields in the event of a 10-point increase in the VIX. Finally, greater excess reserve balances heighten sensitivity to shifts in external risk conditions, increasing bond yields by 16 basis points14.

VI. Policy Implications

A. Overall Policy Recommendations for CADR

This section puts forward key recommendations meant to address those challenges faced by most CADR countries (for detailed country-specific recommendations, see Annex IV). Core recommendations include:

  • 1. Maintain a sound macroeconomic environment. Our study highlights that local currency bond yields are very sensitive to fiscal fundamentals. Anchoring investors’ expectations in moderate fiscal deficits and sustainable debt levels is key to reducing domestic financing costs and alleviating interest payment burdens. Increasing potential growth plays an important role in strengthening tax revenues, improving debt dynamics, and reducing overall debt vulnerabilities and country risk premia.

  • 2. Modernize the legal and regulatory framework for debt markets. The revised framework should allow for greater debt management flexibility and promote the trading and holding of securities. This particularly involves: (i) taxes should not be levied solely on the holders of the coupon; and (ii) eliminating mandatory trading through brokerage houses to reduce transaction costs and increase secondary market activity.

  • 3. Improve market infrastructure to minimize costs and risks for participants. Promote a sound custodian and settlement infrastructure, market makers, and primary dealers to reduce the costs and risks of holding securities and settling transactions.

  • 4. Diversify the investor base to promote a more stable funding and allow for a more flexible debt management. The experiences of the Dominican Republic, Costa Rica, and Honduras in expanding their bases beyond banks and public entities to private pension funds are encouraging. This can be facilitated by, for instance, introducing a regulatory environment that allows for the formation of fully funded pension systems on individual capital accounts, while making sure the tax system does not penalize this type of investment. Also, stimulating the participation of foreign investors through transparent and market-friendly debt management practices, efficient market infrastructure, and fair taxation could be envisaged. However, stimulating the presence of these players requires caution, as a large share of them could bring volatility to the market (GFSR 2020)15.

  • 5. Improve the coordination between debt management and monetary policy. To avoid market fragmentation, the Ministry of Finance should be the sole issuer of securities. Central banks could gradually implement monetary policy relying on government securities. In many countries this involves strengthening the central bank’s balance sheet and operational autonomy. This may need: (i) instituting regular transfers of profits/losses from/to the central bank and, where warranted, recapitalizing the latter with marketable securities; and (ii) mechanisms for the timely provision of government securities for the central bank to execute monetary policy.

  • 6. Improve primary market debt management practices. There is room to (i) expand the issuance of benchmark securities at various maturities that results in a well-defined yield curve and enhanced monetary transmission; (ii) lay out and widely diffuse more strategic MTDS that also define funding actions for at least one year head; and (iii) make auction practices more regular, transparent, and predictable, including by publishing an auction calendar for each of the instruments with predefined auction dates, preferably at regular intervals, regardless of the specific funding needs at each moment. Auctions should be gradually cleared at market prices.

B. Developing LCBM in CADR: Sequencing and Lessons from International Experience

While there are exceptions for particular countries in specific building blocks, the analysis presented in this paper suggests that the CADR region as a whole is in early stages of market development for each of the six building blocks.

In thinking about the appropriate sequence in market development, actions to improve the primary market should take precedence, prioritizing (i) the publication of updated MTDS; (ii) increasing auctions transparency, regularity and predictability; and (iv) enhancing the legal framework and market infrastructure to promote an enabling environment for the primary and money markets. As the primary and money markets become more effective, policies should be geared towards enlarging the investor base, deepening the secondary market, and enhancing the formation of the yield curve. At this stage, adjustments to the regulatory framework should focus in facilitating the creation of collective investment schemes (e.g. private pension funds and mutual funds) and allow for more flexible debt management operations.

While market development needs to be tailored and carefully sequenced to country-specific circumstances, successful experiences of LCBM advancement in peer groups can provide some guidance to CADR. By domain:

  • Debt management and monetary policy coordination. Mexico provides a pragmatic example on how to reduce public debt segmentation by providing the central bank with sufficient treasury bills to implement its monetary operations. By organic law, Banco de Mexico is allowed to purchase federal government securities for the purpose of monetary regulation. A government’s cash deposit is created at the central bank of the same size, terms, and yield as the securities sold.

  • Debt management flexibility. Brazil’s debt management legal framework allows the Ministry of Finance for a flexible and agile decision-making process. The Head of the debt management office is empowered to issue debt and conduct liability management operations at prices below, above, or at par. High levels of transparency and accountability ensure that management decisions are driven by technical considerations.

  • Investor relations. The Dominican Republic has established a transparent relationship with market participants. Approved by the Parliament and published in 2016, the 2016–20 MTDS establishes strategic objectives for the debt portfolio (average maturity, currency risk exposure) and an issuance policy for benchmark instruments to support market development. Annual borrowing plans are couched within the MTDS, with specific target ranges for debt and components, and pre-announced auction calendars.

  • Efficiency in the tax framework. Georgia has implemented a competitive tax framework across key classes of investors, both resident and non-resident, in their primary and secondary bond markets. Reforms focused initially on the “supply side” of government securities and allowed for a uniform tax treatment across the primary and secondary markets. To encourage investment and liquidity in government securities, the authorities also addressed “demand side” considerations, and effectively aligned the tax treatment given to different classes of institutional investors, such as mutual and investment funds.

At the regional level, some initiatives spearheaded by the Central American Bank of Economic Integration (CABEI) have the potential to catalyze LCBM development in CADR, most notably:

  • The creation of a Regional Trading Platform. Such platform would offer clearing, settlements and custody services. This initiative could enhance market infrastructure, facilitate cross-border operations, diversify investor base, and increase bond market liquidity.

  • The creation of a Regional Investment Fund. This fund would allow CABEI and other extra-regional partners to invest in CADR domestic debt

  • Upgrading of sovereigns’ credit ratings. CADR sovereigns would benefit from CABEI’s partial credit guarantee to enhance their credit rating and access on favorable terms the Mexican market

Annex I. The LCBM Framework

The Framework uses a set of indicators which represent the key functionalities of each building block. For any particular country, each indicator is assessed from stage 1 to stage 4, demonstrating the level of functionality or stage of development in the particular building block. The indicators are ordered in a sequential manner, starting with more foundational measures and progressing in sophistication. A composite stage at the building block level can also be calculated, which can help focus the proper sequencing of policy efforts across the six building blocks. The aim of benchmarking at the indicator and building block level is to identify peer countries who have overcome similar challenges, and to draw lessons from them to formulate an LCBM reform plan.

The first step is to determine the stage of development at the indicator level. There are two types of indicators: outcome indicators, which typically show the condition of the building block; and policy indicators, which demonstrate the current practices as employed by the authorities. For most indicators, several binary (yes or no) questions are used to assess the extent to which sound policies and practices are implemented. Countries are rated as 1 (yes) or 0 (no) for each question, and the sum of the ratings determines the stage of the indicator. For several indicators (mostly those in the primary market), a specific question is asked, and the answer determines the stage of the indicator.

The second step is to determine the composite stage at the building block level. Four building blocks (the money market, primary market, secondary market and the investor base) have outcome indicators and policy indicators. A composite stage can be calculated with an equal weighing for both the simple average of the assigned stages of outcome indicators and policy indicators. Two building blocks (market infrastructure and legal and regulatory framework) have only policy indicators. A composite stage can be calculated with a simple average of the assigned stages of policy indicators.

The four stages of LCBM development are determined through a threshold methodology:

  • Stage 1, or nascent stage, where the relevant indicator exhibits no functionality.

  • Stage 2, or developing stage, where the relevant indicator exhibits some functionality, but severe shortcomings exist.

  • Stage 3, or emerging stage, where basic elements of the indicator’s functionality are established; and

  • Stage 4, or mature stage, where the indicator exhibits a considerable degree of functionality. This stage broadly corresponds to the levels/functionality in LCBMs of advanced economies.16

For the 6 CADR countries, yields on local currency bonds come primarily from the Central American Monetary Council repository. For the 6 benchmark EMEs, data come from J.P. Morgan Global Bond Broad Index redemption yields.

The source for macroeconomic forecasts is the Economist Intelligence Unit, through its monthly country reports. Following Laubach (2009) and Jaramillo and Weber (2013), market expectations/forecasts are used to mitigate possible reverse causality between yields and explanatory variables.

10

Typically rates of central banks short-term instruments (bills or deposits).

11

Since our first estimations showed evidence of cross-sectional dependence (De Hoyos and Sarafidis, 2006) and autocorrelation, we shifted to a robust estimation procedure.

12

Baldacci and Kumar (2010) suggest that, ceteris paribus, higher growth could strengthen fiscal positions and may be seen to reduce fiscal vulnerability, leading to lower risk premia.

13

To address potential endogeneity between sovereign bond yields and LCBM indicators we re-estimated equation (1) using lagged values for the latter. The coefficients and significance remained broadly unchanged relative to the base specification with contemporaneous values for the LCBM indicators.

14

Interaction effects are calculated using estimated coefficients and the difference between the best 75th and worst 25th percentile for each LCBM development indicator, in the event of a 10-point increase in the VIX.

15

For instance, April 2020 GFSR Chapter 3 found that financial market depth increases volatility when foreign participation rises beyond a 40 percent threshold.

16

For the investor base building block, stage 4 represents the state of functionalities observed in emerging market economies that are at a more advanced stage of market development.

17

BCCR extensive issuance reflects partly its negative net worth of about 6½ percent of GDP (as of December 2019).

18

There has been plans for BCCR to issue securities with maturities up to 3 years, leaving the longer segment to the government. In practice, the government has also issued shorter-term instruments to meet cash and debt management needs.

19

The relatively large share of central bank securities originates from the quasi-fiscal operations of 2003–2004, where BCDR issued instruments to deal with a banking crisis.

20

The creation of benchmark bonds is somewhat hindered by recurrent changes in the international securities identification number (ISIN), which occurs at least once a year for each instrument.
