The Fiscal Costs of Contingent Liabilities
A New Dataset

We construct the first comprehensive dataset of contingent liability realizations in advanced and emerging markets for the period 1990–2014. We find that contingent liability realizations are a major source of fiscal distress. The average fiscal cost of a contingent liability realization is 6 percent of GDP but costs can be as high as 40 percent for major financial sector bailouts. Contingent liability realizations are correlated among each other and tend to occur during periods of growth reversals and crises, accentuating pressure on the budget during already difficult times. Countries with stronger institutions are able to better control and address the underlying risks so that they are less exposed to contingent liability realizations.

Abstract

We construct the first comprehensive dataset of contingent liability realizations in advanced and emerging markets for the period 1990–2014. We find that contingent liability realizations are a major source of fiscal distress. The average fiscal cost of a contingent liability realization is 6 percent of GDP but costs can be as high as 40 percent for major financial sector bailouts. Contingent liability realizations are correlated among each other and tend to occur during periods of growth reversals and crises, accentuating pressure on the budget during already difficult times. Countries with stronger institutions are able to better control and address the underlying risks so that they are less exposed to contingent liability realizations.

I. Introduction1

Contingent liabilities have been one of the largest sources of fiscal risk. In several cases, failure to disclose and prepare for such risks has led to large increases in public debt and triggered fiscal crises (Cebotari, 2008; IMF, 2012). The materialization of contingent liabilities, together with exchange rate depreciations, have been found to be behind major unexpected increases in the debt-to GDP ratio over the last 10 to 15 years (IMF, 2003; Cebotari and others, 2009; and Jaramillo and Mulas-Granados, 2015), and the associated fiscal costs (in terms of fiscal outlays) can be very high. During the Asian and Latin American crises, for example, these fiscal costs amounted to up to 50 percent of GDP (Honohan and Klingebiel, 2000); fiscal costs related to contingent liabilities from natural disasters have historically been as high as 10 percent of GDP (Freeman and others, 2003). More recently, the global financial crisis and the numerous episodes of bank restructuring or recapitalization have again had a major toll on public finances, making clear the large implicit guarantees that governments tend to give to the financial sector (Amoglobeli and others, 2015; and IMF, 2015).

This study provides the first comprehensive dataset on contingent liability materializations, encompassing a broad range of contingent liabilities, from financial ones to those originating from subnational governments, natural disasters, public-private partnerships (PPPs), legal cases, state-owned enterprises and private enterprises. The dataset collects information for 80 advanced and emerging economies for the period 1990–2014. For each year and country where a contingent liability materialized, the dataset provides information on the start and end year of the episode, on the type of contingent liability, type of fiscal response, fiscal cost and triggers as well as some additional descriptive information.

We use this novel dataset to describe a number of previously not available stylized facts about contingent liability realizations. We find a total of 230 contingent liability episodes, and for 174 of those we were able to identify the associated fiscal cost. We find that the financial sector accounts for the largest fraction of those episodes with highest costs, but subnational government bailouts, support to State-Owned Enterprises (SOEs) and legal liabilities can also impose very substantial costs. The distribution of fiscal cost is highly skewed indicating that very large costs are rare (namely fiscal costs above 20 percent of GDP), but still the average fiscal cost amounts to about 6 percent of GDP while the median fiscal cost is about 2 percent of GDP. We find that contingent liability realizations are highly correlated with each other and with major crises. In particular, emerging markets suffered a large number of costly contingent liability realizations during the Asian Crisis while the same was true for advanced economies during the Global Financial Crisis.

Our dataset indicates that a macro-relevant contingent liability realization occurs on average every 12 years per country. They tend to occur at times of crisis and additionally many of these materializations happen concurrently—when it rains it pours—putting considerable strain on government finances. Through basic logit regressions, we highlight that contingent liability materializations tend to follow periods of high growth and coincide with low growth periods and banking crises. Lastly, we show that countries with stronger institutions and low growth volatility tend to suffer less from contingent liability realizations, indicating that much can be done at an institutional level to prevent costly shocks to the public finances.

The paper is structured as follows. Section II provides the definition of contingent liabilities employed and relates our work to the literature. Section III explains the methodology we use to create the dataset and illustrates some descriptive statistics. Section IV studies the impact of macroeconomic and institutional factors on the probability of a contingent liability realization and average fiscal costs. Section V concludes.

II. Background

A. Defining Contingent Liabilities and Their Fiscal Cost

The Public Sector Debt Statistics Guide (IMF, 2011) defines contingent liabilities (CLs) as obligations that do not arise unless particular discrete events occur in the future. As such, they differ from direct liabilities where the settlement date is fixed at the time when the nominal obligation is set (Towe, 1991). On a contractual basis, we can distinguish between explicit and implicit CLs, whereby the former entail obligations which have been set by a particular law or contract; whereas the latter involve a moral obligation or expected responsibility of the government which is not established by law or contract but is based on public expectations, political pressures, and the overall role of the state as society understands it.

Within the range of explicit CLs, one can distinguish guarantees for non-sovereign borrowing and obligations issued to subnational governments and public and private sector entities. These include state guarantees as part of public-private partnership contracts; guarantees for various types of loans, such as mortgages, student, and small business loans; state insurance schemes (for commercial bank deposits, minimum returns from private pension funds, to protect farmers against droughts or floods, for airline disaster or war risk); and export trade guarantees. Implicit CLs encompass default of a subnational government and public or private entity on nonguaranteed debt and other liabilities; this includes bank failure, investment failure of a nonguaranteed pension fund, employment fund or social security fund, and environmental damage, disaster relief, and military financing.2

Under accrual accounting, CLs are not recognized as liabilities and expenses in government accounts. However, for each class of CL the government is in theory required to disclose in notes to financial statements (except when the possibility of any payment is remote) a description of the nature of the contingent liability and, where practicable: (i) an estimate of the financial effect, e.g., the present value of any payments; (ii) an indication of the uncertainties about amounts or timing; and (iii) possible reimbursement. On the other hand, if the probability that payments would have to be made is more than 50 percent, and the payments can be reliably estimated, then the government is required to recognize in its accounts a liability (referred to as provision) and a corresponding expense. Disclosure requirements include: (i) stocks at the beginning and end of the period; (ii) breakdown of the flows during the period; (iii) description of the nature of the obligation and the timing of payments; (iv) indication of uncertainties regarding amount and timing; and (v) the amount of any reimbursement. Under cash accounting, standards allow, but do not require, disclosure of information about contingent liabilities along the lines set out above.

In practice, only the most advanced countries provide a comprehensive overview of their CLs and even then implicit CLs are often not fully addressed. In fact, it is not even obvious whether a government should be disclosing and discussing all implicit CLs for fear of making a vague commitment stronger and thus creating moral hazard (see Irwin, 2015 on the issues surrounding the discussion of fiscal risks related to the financial sector in fiscal reporting). CLs thus often get realized “out of the blue” and inflict substantial costs on government finances. The Fiscal Transparency Code (IMF, 2014) indicates as best practice identifying, quantifying and disclosing all government guarantees and their probability of being called, total obligations under public-private partnership contracts, explicit government support to financial sector, and all direct and indirect support between the government and public corporations at least annually. Regarding implicit contingent liabilities, the Transparency Code endorses disclosing the main specific risks to the fiscal forecast in a summary report, along with estimates of their magnitude and, where practicable, their likelihood. The fiscal risks from natural disasters should also be managed according to a published strategy.

The materialization of contingent liabilities can have various impacts and associated costs on the economy. The literature distinguishes between direct and indirect fiscal costs, as well as gross and net fiscal costs. Following Laeven and Valencia (2012), we consider here as fiscal costs gross fiscal outlays and immediate changes in the government financial position directly due to the CL realization.3 Prime examples include a government bailout of a bank, emergency assistance after an earthquake or debt assumption of a troubled state-owned enterprise (SOE).

B. Literature Review

Governments that want to avoid the danger of sudden fiscal instability and accomplish their long-term policy objectives must have a good understanding of both their direct and contingent liabilities and must be able to handle them appropriately. There exists a sizeable literature on how to define, estimate, disclose, manage, and contain contingent liabilities. Early contributions include Polackova (1998) and Polackova-Brixi and Schick (2002), who delineate direct and contingent fiscal risks, and discuss some country experiences. Cebotari (2008) in a thorough overview paper, outlines the issues and practices related to the accounting and management of contingent liabilities. Cebotari and others (2009) present a comprehensive analysis of the sources of contingent liabilities, and practical guidelines for the disclosure and management of (contingent) fiscal risks in light of existing country experiences. They conclude that contingent liabilities are a key source of fiscal risk.

Indeed, within the range of fiscal risks, contingent liabilities have often been claimed to have one of the costliest impacts on the budget (IMF 2003), and to account for the bulk of so-called “hidden deficits,” i.e., increases in public debt that are not explained by headline fiscal balances (Kharas and Mishra, 2001).4 Studies such as Weber (2012) and Jaramillo and Mulas-Granados (2015) show that factors other than low growth and headline fiscal deficits were the main contributors to the increase in public debt in low income, emerging and advanced economies since the 1980s. These could reflect several (residual) factors, such as contingent liability realizations and exchange rate developments, which are difficult to disentangle without a detailed look at the data.5

Financial sector related contingent liability realizations have often been a major burden for government finances. Through cross-country panel regressions, Weber (2012) finds that fiscal costs arising from banking crises (using the dataset by Laeven and Valencia, 2012) were significant sources of discrepancy between debt stock variations and deficit changes. Similarly, there exists a large literature that attempts to quantify the fiscal costs of CL realizations related to the financial sector (Honohan and Klingebiel, 2000; Hoelscher and Quintyn, 2003; Laeven and Valencia, 2008 and 2012; and Amoglobeli and others, 2015).6

Apart from the financial sector, however, evidence on the cost and frequency of CL realizations is limited. Relevant papers include Cordes and others (2014) who identify a number of episodes of subnational government bailouts over the past three decades in nine advanced and emerging countries. Flanagan (2008) discusses large Eastern European (legal) contingent liabilities largely related to frozen saving or foreign currency deposits following the breakup of the Soviet Union and Yugoslavia. An important study and closest in spirit to our work is Cebotari and others (2009), who list examples for a broad range of contingent liability realizations compiled from various sources. On natural disasters, the International Disasters Database (2015) contains a detailed overview of the human cost and physical damages of all large natural disasters but does not have information on fiscal costs. An IMF (2012) Board Paper analyzes in detail the sources of large unexpected increases in general government debt in 10 advanced countries between 2007 and 2010. The analysis shows that financial sector and other type of contingent liabilities related to quasi-fiscal activity of SOEs and PPPs account for one fifth of the unexpected rise in debt in these countries during the recent crisis.7 However, such detailed analysis is still limited to a few advanced economies and to recent years.

This lack of data has made it difficult to study issues related to the timing and likelihood of CL realizations, their fiscal impact and average fiscal cost. In addition, insights on the skewness of the distribution of fiscal risks associated with CL realizations (Gaspar and others, 2015), and information regarding the institutional frameworks that could reduce the probability of occurrence are similarly crucial for the management of CL shocks. This paper aims to fill this gap by constructing a comprehensive database of gross direct fiscal costs of a broad set of macro-relevant contingent liability realizations in advanced and emerging countries since the 1990s.

III. Dataset

A. Methodology

Our dataset spans a total of 80 countries—34 advanced economies (AEs) and 46 emerging market economies (EMEs)—over the period 1990–2014.8 We use a broad definition of CLs. Specifically, we follow the definition in Cebotari and others (2009) to obtain seven contingent liability categories: Financial Sector, SOEs, Subnational Government, Natural Disasters, Private non-Financial Sector, Legal, and PPPs.9

Our main sources of information are IMF Staff Reports (SRs). SRs are written as part of the annual IMF Article IV surveillance mission of member states and contain detailed observations on all macro-economic sectors of the economy; (when available, reports from quarterly or semi-annual reviews of an IMF program were also considered). As such, SRs are excellent sources of information on the realization of CLs. To guide our search of SRs we identify countries and years with high positive stock-flow adjustments or large and unexpected debt increases. Additionally, we rely on information from previously published databases relating to specific types of CL realizations. To summarize, we adopt a data collection strategy relying on three pillars:

  • 1) We build a baseline database combining all previously available data on CL realizations and cross-check these data using SRs;

  • 2) We use stock-flow analysis and debt forecast error decomposition to guide us towards country-years with potential CL episodes;

  • 3) We conduct key word searches of all remaining SRs;

Combining existing data sources

As discussed in section II, there already exists a fairly large, but scattered, amount of information on CL realizations. We combined information from Laeven and Valencia (2008, 2012) and Eurostat (2015) on the fiscal cost of financial sector CL realizations with data from Cordes and others (2014) on subnational government bailouts, data on contingent liability realizations in Eastern Europe from Flanagan (2008), data on natural disasters from the International Disasters Database hosted by the University of Leuven, and lastly data on various different episodes from Cebotari and others (2009).10

Laeven and Valencia (2008) provide a detailed overview of systemic banking crises and the associated fiscal costs, building on previous work by Hoelscher and Quintyn (2003) and Honohan and Klingebiel (2000). In 2012, the database was updated to include the Global Financial Crisis (Laeven and Valencia, 2012). We rely on the Laeven and Valencia data for the fiscal cost of all large banking crises, except for episodes in the European Union after 2007 for which we use Eurostat (2015) data. Eurostat provides a very detailed assessment of the fiscal cost of financial sector support for each EU country for the period 2007–14, differentiating between deficit generating expenditures and below-the-line items. Lastly, we complement the Laevan and Valencia and Eurostat data with additional information from Honohan and Klingebiel (2000), relating to non-systemic banking crises.

On subnational government bailouts, we take Cordes and others (2014) data and crosscheck it using SRs for consistency when necessary. Similarly, we crosscheck the data provided by Flanagan (2008) on large Eastern European contingent liabilities. Using the data on natural disasters from the International Disasters Database, we identify all episodes that caused damages of at least one percent of GDP. We then consult to the SRs for the relevant years and countries to identify the associated fiscal costs. Lastly, we take and crosscheck the detailed information provided by Cebotari and others (2009) on a variety of contingent liability realizations.

Stock-flow adjustments and forecast error decomposition

To guide our search towards countries and years that might have experienced a CL realization we use two different techniques: stock flow adjustments and forecast error decomposition of debt.

A stock-flow adjustment is the discrepancy between the annual change in gross public debt and the budget deficit (Weber, 2012). Changes in debt that are not explained by the deficit could indicate a CL realization but can also reflect changes in the exchange rate among other factors. The definition follows from the basic debt accumulation equation:

Dt=Dt1OBt+SFt(1)

where Dt denotes gross public debt in nominal terms at time t, OBt denotes the overall balance and SFt denotes the residual term referred to as the stock flow adjustment. Dividing both sides by nominal GDP at time t and rearranging we get

dt=11+γtdt1obt+sftdtdt1=γt1+γtdt1obt+sft(2)Δdt=λtdt1obt+sft

where γt denotes the nominal GDP growth rate at time t, and small letters denote variables in percent of GDP. Δdt denotes the annual change in gross public debt to GDP ratio, which depends negatively on GDP growth (captured by the term λt=γt1+γt) and the overall balance, with other factors such as debt assumptions captured in the residual sft.

To calculate the forecast error we go one step further. We decompose unexpected rises in the debt-to-GDP ratio into an unexpected rise in the deficit and an unexpected growth slowdown, with the residual term capturing the unexpected increase in debt due to factors such as the realization of contingent liabilities. The decomposition follows from the stock flow adjustment equation:

Δd˜t=λ˜tdt1ob˜t+ε(3)

where x˜t=xtEt1xt is the difference between the IMF World Economic Outlook (WEO) forecast of variable x for year t made in year t-1 and outturns for year t based on WEO data submitted in year t+1 (Cebotari and others, 2009). The variable εt is the forecast error residual. To calculate our variables of interest (εt and sft) we use data on fiscal balances, interest payments, public debt, and GDP coming from the IMF's WEO and Fiscal Monitor databases. We compare forecast data to actual realizations when checking for the forecast error.

We then compile a database where we identify country-years with large forecast errors and/or stock-flow adjustments. Figure 1 plots the distribution of positive stock flow adjustments and forecast errors, which is heavily right skewed. For those observations in the right tail of the distribution we follow-up with as many sources as possible to verify whether indeed a CL realization occurred.

Figure 1.

While this is a useful exercise and allows us to identify some likely CL episodes, it is nevertheless no more than a first indicator. For example, if a CL realization is fully captured as an expenditure and thus enters the deficit, then the stock-flow adjustment will be zero. In this case, we would miss it by relying on the above analysis. At the same time, changes in debt may be not due to contingent events but actually planned by an explicit contract. Furthermore, CL realizations might sometimes be forecast, if for instance the shock occurs at time t but the assumption of debt by the government is set for time t+1. In this case, they would not be a source of forecast error. Stock flow adjustment and forecast error decompositions of debt might thus point to false positives or might miss true realizations. This leads us to our next and key pillar in the data construction methodology.

Key word searches

The last pillar is a “brute force” approach. Only in recent years (and then also not consistently) have CLs been receiving explicit attention in SRs, so we rely on key word searches to try and identify and/or verify CL realizations. We search for terms such as “recapitalization,” “capital injection,” “restructuring,” “natural disaster,” “contingent,” “SOEs,” “PPP,” etc. Furthermore, footnotes to the fiscal tables in the SRs often provide important information. When necessary (and available) we complement the information obtained from the SRs with additional sources such as country-specific Debt Sustainability Analyses and Selected Issues Papers, IMF Fiscal Transparency Evaluations, academic papers and reports by Ministries of Finance and Central Banks.

For each contingent liability episode identified, we record (as far as possible): the start year, the end year, whether it was an implicit or explicit contingent liability, the type (financial sector, SOE, etc.), the type of fiscal response (recapitalization, etc.), the fiscal cost, the trigger, the source and a short verbal description. Appendix D provides an overview of all the data collected.

B. Descriptive Statistics

We capture a total of 230 CL realizations, including 174 for which we were able to identify the fiscal cost.12 Figure 2 plots the distribution of the fiscal cost of these CL realizations.13 The distribution is highly skewed—the mean CL realization is 6.1 percent of GDP while the median is significantly smaller, but not trivial, at 2.3 percent.14 The distribution has a long tail, with a few episodes exceeding a fiscal cost of 20 percent of GDP and a fairly large number of realizations with a fiscal cost over 10 percent of GDP. CL realizations can thus have a very significant impact on countries’ public finances.

Figure 3 plots the 174 CL realizations by year and type of CL while Table 1 shows the number of episodes, as well as the average and maximum fiscal cost by type of CL realization to shed some more light on the data. The evidence reported highlights that financial sector CL realizations tend to be the most costly, with an average cost of 9.7 percent of GDP and a substantial number of episodes with fiscal costs of over 20 percent of GDP.15 Nevertheless, several of the other types of CL realizations also pose significant risks. More than half of the episodes in our dataset stem from non-financial sector related CL realizations. Subnational government bailouts, SOE support and legal CLs stand out, leading to costs as high as 12–15 percent of GDP.16, 17 Figure 3 also highlights that CL realizations tend to be bunched together; the Asian Crisis in 1997–98 and the Global Financial Crisis in 2008 are both clearly visible. One interesting observation is that the emerging market economies that experienced large financial sector related CL realizations during the Asian Crisis did not experience such large fiscal costs arising from CLs during the Global Financial Crisis.

To illustrate the bunching of CL realizations during crisis times further, both across types and across countries, consider Figure 4, which plots the total number of CL realizations by type and year. In particular, 2008–09 stand out with over 30 CL realizations in 2008 alone. The figure also shows that during the Asian crisis and the Global Financial Crisis, total CL realizations were above 3 percent of the total GDP of the 80 countries in our sample. As one would expect, the largest part of these episodes are linked to the financial sector, but there was also a substantial increase in the number of episodes with government support for SOEs and private non-financial entities in that period.

Figure 5 highlights that both AEs and EMEs were affected in 2008, but the largest fiscal costs were concentrated in AEs. On the other hand, during the Asian crisis, CL realizations were concentrated nearly exclusively in EMEs. Figure 6 stresses the point that the largest risk for AEs is clearly associated with the financial sector, while for EMEs the picture is somewhat more mixed, with legal and natural disaster related CLs also standing out. Lastly, it is worth pointing out that the vast majority of CL realizations we find stems from implicit rather than explicit CLs (over 80 percent). This underscores that assessments of CL realizations need to go well beyond the explicit stock of government guarantees.

Using our data on contingent liability realizations, it is possible to calculate the (ex-post) probability of a CL realization and the average fiscal cost conditional on a realization.18 To be able to have a dataset that only has one observation per country and year, we sum all episodes that start in exactly the same year in the same country. Table 2 below then shows that the average country in our sample has an 8.7 percent probability of incurring a macro relevant CL realization in any given year.19 This translates into one CL realization every 12 years. In other words, the average country would be expected to have experienced a CL realization twice in the twenty five-year sample period, with a fiscal cost of 6.1 percent of GDP per episode. Similarly, the average country has a 2.8 percent probability of suffering a CL realization of at least 5 percent of GDP and the fiscal cost conditional on the realization is then 15.5 percent of GDP. These numbers make clear that while a truly large event is fairly rare, it can potentially cause substantial damage to a country's debt sustainability when it occurs.20

One should note that averages mask important heterogeneity. Figure 7 shows that over the twenty five-year period we analyze, countries have experienced an average of about 2 CL realizations (median of 2). Several countries have suffered up to 4–5 CL realizations. Table 3 below depicts some specific country experiences in our sample. Brazil, for example, experienced a CL realization of 8.3 percent of GDP on average every five to six years. Ukraine similarly suffered a CL realization of average 2.9 percent of GDP every six years. These repeated large realizations represent a very significant burden on government finances. In the following section we analyze in more detail when CL realizations occur and how country characteristics impact realizations.

IV. Contingent Liability Realizations: When, How, Why

This section is divided into two subsections. First, we show that CL realizations tend to occur during times of crisis and are associated with a significant worsening in the overall fiscal balance and large increases in the debt to GDP ratio. Moreover, we study the triggers of contingent liability realizations in more detail and show that even when controlling for systemic crises, boom-bust cycles have high explanatory power in accounting for the timing of CL realizations. Overall, we highlight that CL realizations tend to follow periods of high growth and coincide with periods of low growth, and thus have a magnifying effect when the budget is already strained. The second subsection studies the link between institutions and CL realizations. We show that countries with stronger institutions and lower volatility of growth are less exposed to CLs. Strengthening institutions thus appears to be a key step in preventing costly CL realizations.

A. The Macro-Economy and Contingent Liability Realizations

The recent global financial crisis and the subsequent spike in government debt have highlighted how vulnerable government debt sustainability can be to large shocks. Figure 8 uses event study graphs to show that contingent liability realizations are associated with a significant worsening in the overall fiscal balance, a large increase in debt and a short but steep drop in growth. To obtain these graphs, we regress the variable of interest on a set of period fixed effects while controlling for event fixed effects for our sample of CL realizations. We then plot the coefficients on the period fixed effects five years prior and 10 years after a contingent liability realization. On average, debt increases by over 15 percent of GDP during a CL realization. It rises for roughly three years and then stabilizes, albeit at a higher level than before the CL realization. The overall fiscal balance falls by about 2 percentage points as a share of GDP on average and then stays below the pre-event level for an extended period of time. Lastly, GDP growth drops sharply for two years and then reverts to trend.

These results offer some preliminary indication that CL realizations tend to occur during periods of economic stress, which they potentially amplify. Consider the average increase in the debt to GDP ratio. While the average fiscal cost of a CL realization is 6 percent of GDP, debt increases by 15 percent of GDP on average. To shed some more light on this issue we calculate the correlation between CL realizations and the occurrence of major crises. Table 4 highlights that the two are highly correlated. In particular, banking crises coincide with financial sector CL realizations. Moreover, Table 5 shows that different types of CL realizations are also correlated among each other; although the correlation coefficients are relatively small, they tend to be significant except for non-financial private sector CLs.21 Financial sector CL realizations, for example, are significantly correlated with SOE, subnational and PPP CLs. Overall, we can observe that contingent liability realizations tend to occur during times of crisis and also tend to be correlated among each other—all these factors compounding the negative impact on the government budget. From a fiscal perspective: When it rains, it pours.

To understand whether it is only during times of systemic crisis that CL realizations are more likely or whether general economic downturns are also associated with a higher probability of a CL realization we estimate the following equation:

logit(E(Yi|Xi)=xiβ(4)

where Yi is an indicator for a CL realization, xi is a vector of covariates and β is a vector of regression coefficients. In particular, we include measures of GDP growth, inflation, and exchange rate in the set of covariates to see how the macroeconomic environment affects the probability of a CL realization. We exclude natural disasters from the analysis since they are likely orthogonal to macroeconomic variables.

Column 1 of Table 6 shows that the probability of a CL realization is positively correlated with lagged growth and negatively correlated with contemporaneous growth.22 This finding may suggest that economic booms or overheating may coincide with excessive risk taking (e.g., in credit markets), which eventually may trigger a CL realization when a sudden growth reversal takes place. Weak growth may make it more likely that banks suffer from NPLs and need to be recapitalized, and that SOEs are loss making and need central government support. Yet, the reverse could also be true, namely that the CL realization as a large fiscal shock (e.g., triggered by a banking crisis) could negatively affect growth performance. To check whether this result is robust to the inclusion of other covariates we first add contemporaneous and lagged monetary variables (inflation and exchange rate) together with a dummy for country specific systemic banking crises in columns 2 and 5, and contemporaneous and lagged volatility of growth in columns 3 and 6.23 Country fixed effects are included in columns 4 and 7. The result for GDP growth remains statistically significant in all specifications. Controlling for crises does not alter the result even though the magnitude is somewhat reduced, and confirms that CL realizations are correlated with crises. On the other hand, past inflation and depreciations do not seem to affect the probability of CL realizations, neither does volatility of growth. Thus, it seems to be mainly episodes of growth reversals that can act as triggers for CL realizations.24 Future work could usefully study these linkages in more detail.

B. Institutions and Contingent Liability Realizations

Fiscal transparency and accountability have long been advocated by institutions such as the IMF as a way to identify, monitor, and ultimately prevent fiscal risks. In this section we study how the quality of government institutions and thus ultimately the ability and will of government to deal with the underlying problems that can generate CL realizations relates to the average fiscal cost of CLs. Recall from Table 2 above, that countries have on average an 8.7 percent probability of suffering a CL realization in any given year and the average fiscal cost of such realization is then 6.1 percent of GDP. This gives an expected cost of 0.53 percent of GDP each year.25 The expected cost is a convenient way of summarizing in one metric both the frequency as well as the size of CL realizations. Note that this means countries should expect on average ½ percent of GDP of debt annually due to CL materializations, and roughly 10 percentage points rise in debt to GDP ratio over a twenty-year period.

Figure 9 below compares the expected fiscal cost for countries with above and below average corruption scores. It becomes immediately apparent that countries with a lower corruption score have a lower expected cost.

Figure 10 conducts the same exercise, this time using bureaucratic quality as the discriminating variable.26 Again, a significant difference between good and bad performers becomes apparent. The difference is of a much larger magnitude, which seems intuitive given that one would expect bureaucratic quality to be much more directly important for strong fiscal institutions than corruption. The difference is quantitatively important—the expected fiscal cost is over 30 percent higher in countries with below median bureaucratic quality than in those with an above median score.

One possible mechanism that could link low bureaucratic quality to higher fiscal costs of CL realizations is the higher volatility of growth in countries with weak institutions. While this is a well-known phenomenon (Acemoglu and others, 2003) Figure 11 also illustrates the point. Panel 11(a) shows that the standard deviation of growth in countries with below median bureaucratic quality is nearly double that in countries with an above median score, while panel 11(b) illustrates that the expected cost of CL realizations is nearly 50 percent higher in countries with above median volatility of growth than in those with below median volatility.27

An alternative hypothesis for the link from institutions to CL realizations could be that weak institutions allow the sort of disequilibria to build, which ultimately lead to government bailouts. Alternatively, countries with weak governance abilities might not be able to solve the moral hazard problem inherent in implicit government guarantees, therefore (ex post) leading to more and more costly CL realizations. Similarly, countries with weaker institutions are less likely to analyze and understand risks from CLs; and therefore they are not always able to take mitigating action before they occur, either by not entering into contracts or through policy-actions such as regulation, risk-sharing, and stronger governance (see Cebotari and others, 2009).

V. Conclusion

In this study we presented the first comprehensive database on realizations of contingent liabilities. We constructed the dataset by compiling pre-existing datasets and adding novel information coming mostly from IMF country-specific reports. The database documents more than 200 episodes across 80 countries over the period 1990–2014. For each episode it provides information regarding the size and type of liability and the type of fiscal response.

A first analysis of the data reveals that the costliest CL shocks are related to the financial sector; CL realizations tend to occur at times of crisis and many of these materializations occur at the same time (when it rains it pours); boom-bust cycles can act as triggers for the materialization of CLs; and countries with stronger institutions and lower volatility of growth tend to suffer less from CL realizations, indicating that much can be done institutionally to prevent costly shocks to the government budget.

In this context, fiscal frameworks could be strengthened, together with the analysis and understanding of these risks and the reporting of CLs. Once fiscal risks, including CLs, are well understood, governments could consider what steps can be taken to minimize the probability that they are realized. A few possible measures include limiting the direct exposure of public sector entities, requiring beneficiaries of guarantees to post collateral and requiring banks to hold sufficient capital.

While being the most comprehensive dataset so far, some episodes may not have been captured in the present paper. Extending the dataset to pre-1990 periods and including low-income countries would be worthwhile extensions and would allow for a more comprehensive picture of contingent liability realizations.

The dataset as it stands already opens several avenues for research. It allows for more analytical work on the causes and consequences of contingent liability realizations and comparisons across countries and time. Ultimately, the aim would be to provide grounds for a better understanding on how to prevent these shocks and how to manage them once they materialize.

The start date reflects the date reported in IMF SRs or external sources and may at times not exactly coincide with the actual start date of a contingent liability realization.

The end date reflects the date reported in IMF SRs or external sources and may at times not exactly coincide with the actual end date of a contingent liability realization. For episodes that were still ongoing while the data was being collected, 2014 was chosen as the cut-off year.

For natural disasters, estimated damages from EMDAT are reported. These are not the fiscal costs.
