Introduction

Sustainably integrating China into the global economy has been a pivotal event in recent decades and will continue to lead global economic developments. Trade and production integration naturally came first as market-based reforms began more than four decades ago, but integration into global financial markets is now assuming central importance. Smooth integration will ensure that world resources are channeled to their most productive uses globally and that global risks are efficiently shared across countries and sectors. Both China and its trading partners stand to benefit from these developments.

This chapter offers a preliminary assessment of the potential for China’s further integration into global financial markets—especially into the international bond market—and highlights the possible challenges of further financial integration.

The chapter uses a two-step approach. The first half benchmarks the increasingly central role of China in global financial markets by analyzing China’s evolving stock and bond markets, as well as by comparing them to those of key international markets, such as the United States, the euro area, Japan, and regional peers like India and the Republic of Korea. It then analyzes foreign participation in Chinese bonds as well as bond yield differentials (such as differences between foreign-exchange-hedged and unhedged yields). The results make clear that further successful liberalization of the Chinese bond market would need to encompass not only the bond market itself, but also further development of other markets, notably the foreign exchange market.

The second half of the chapter focuses on the potential challenges of further inter-national integration of the Chinese bond market. The ongoing normalization of US monetary policy, for example, could pose risks for many emerging market economies, including China. The chapter therefore explores the sensitivity of China’s capital inflows to the global financial cycle and evaluates how this could increase as integration proceeds. It concludes that room is ample for further integration, especially in the bond market, but this process cannot occur in isolation, given the broader economic integration necessary for sustainable efficiency and stability.

China’s Financial Markets in the Global Context

Figure 2.1 illustrates China’s increasing importance in global financial markets, reflecting the growth of its financial markets relative to the size of the real domestic economy (panel 1) and the fast-growing real economy itself, with its rising ratio to world GDP (panel 2). Chinese bond market capitalization grew from about 1 percent of global GDP at the start of the 2000s to 9 percent by the end of 2017.

Rising stock market capitalization is a bit smaller but still striking, reaching about 10 percent of global GDP in 2017 from about 2 percent of global GDP in 2002. Much more impressively—but also pointing to potential financial stability challenges—the assets of the Chinese banking system skyrocketed from 1 percent of global GDP in 2002 to almost 50 percent in 2017.

At the same time, foreign participation in China’s stock and bond markets has risen, although it remains relatively low compared with international peers. Helped by landmark reforms in Chinese financial markets (such as the Shanghai–Hong Kong and Shenzhen–Hong Kong Stock Connect Programs), as well as by the inclusion of Chinese equities in the MSCI index,1 foreign participation in the Chinese stock market increased slightly in recent years (see Figure 2.2). Foreign equity holdings are about 2.4 percent of total Chinese equity market capitalization. Foreign participation in Chinese bond markets is similarly small, at only about 1.6 percent of the total value of bonds outstanding, with that share remaining stable in recent years.

In contrast, as Figure 2.3 (panel 1) shows, foreign participation in the stock markets of the United States (about 35 percent in 2017), Korea (33 percent), and Japan (17 percent) is much more important than in China. Only foreign participation in India’s stock markets is comparably limited (2.8 percent in 2017). The evidence is similar for the bond market (panel 2), with foreign participation in China’s bond markets substantially below its peers, including India.

Limited foreign participation in China’s financial markets is also visible in IMF balance of payments data, highlighting the wide scope for further external integration of those markets. The international investment position of China as of 2015 showed that its liabilities to foreigners (claims of nonresidents on Chinese residents) were about 40 percent of domestic GDP (Figure 2.4, panel 1), substantially below the levels of the United States (about 160 percent of GDP) and Japan (115 percent), as well as Korea (65 percent) and India (55 percent).

The composition of these liabilities across countries also reflects the scope for further integration of China in both equity and, especially, bond markets. The share of portfolio equity and bonds is just one-fifth of total Chinese external liabilities, a much lower share than for the United States (three-quarters of total external liabilities), Japan (three-fifths of total external liabilities), Korea (three-fifths of total external liabilities), and India (two-fifths of total external liabilities). A similar picture (Figure 2.4, panel 2) prevails on the asset side (Chinese residents’ holdings of foreign assets), highlighting the still-modest external diversification of Chinese wealth, especially of portfolio equity and debt.

Further Liberalization of China’s Bond Market

So, while the overall size of financial markets in China has grown, foreign sector participation has increased only slightly and international integration relative to peer economies remains low. This section explores the characteristics of the country’s bond markets and the types of bonds that might attract foreign investors through further cross-border liberalization.2

Chinese bonds outstanding at the end of 2017 were high in absolute terms, with a stock of about $11 trillion at the end of 2017 (Figure 2.5), more than Korea (about $2 trillion), and similar to Japan ($12 trillion), but not comparable yet with the euro area ($20 trillion) or the United States ($41 trillion).

Note:

1 Government bonds cover bonds issued by the general government (central, state, and local government accounts; social security funds; and nonmarket, nonprofit institutions controlled and mainly financed by government units).

Unlike Japan, Korea, and even the euro area and the United States, the issuers of Chinese bonds are more concentrated in the nongovernment sector (although for China that includes important state-owned enterprises and various government-sponsored vehicles). Nonetheless, most foreign holdings of Chinese bonds are concentrated in government instruments (Figure 2.6). This situation resembles that of Japan and Korea, but is far from those of the United States, India, and euro area countries such as Germany, where nonresidents contribute a substantial fraction of the private sector’s bond financing.3 In this context, further liberalization of the bond market in China could help the private sector diversify funding, improve liquidity, and lengthen borrowing maturities.

In terms of pricing, the evolution of the Chinese bond yield curve reflects higher nominal yields than either US or euro area bonds, as well as a degree of comovement in the evolution of Chinese yields relative to those countries despite China’s closed capital account. Figure 2.7 depicts the bond yields in April 2018, as well as the yield curve before the beginning of monetary normalization in the United States in December 2015 (depicted by the dashed lines in Figure 2.7).

Synchronized yield developments between China and the rest of the world do not necessarily imply the existence of big cross-currency arbitrage opportunities, because of both remaining capital controls and the relatively high cost of hedging currency risk. Figure 2.8 captures the relative hedged yield differentials between similar Chinese and US government bonds, using either onshore or offshore forwards.4 The hedged China-foreign yield differentials are not as positive as the unhedged ones, especially when using nondeliverable offshore forwards (depicted by the green lines in Figure 2.8). Comparing covered 12-month with 3-month differentials, shorter maturity investments hedged onshore look somewhat more attractive to foreign investors.5

In this context, it could be envisaged that the successful liberalization of the Chinese bond market would encompass not only further regulatory measures linked to the bond market itself (that is, by allowing further foreign participation in terms of buying and issuing bonds onshore), but that the resulting inflows and outflows of bonds would depend on several factors, including covered interest parity considerations, where both interest rate differentials and foreign exchange market considerations are important.6

Market Opening and Increasing External Influences

Further capital account liberalization, including deepening of the bond market, would increase the impact of current policies in key global financial centers (the euro area, Japan, the United States) on capital flows to China. While the capital flows literature (for example, Calvo, Leiderman, and Reinhart 1993) has covered the role of a number of external variables—variables now usually labelled as “push” factors—a consensus has emerged on the role of US monetary policy (including unconventional monetary policies, as reflected in Fratzscher, Lo Duca, and Straub [2018]), risk aversion (as captured by the US Chicago Board Options Exchange Volatility Index, or VIX, as stressed by Forbes and Warnock [2012], among others), and the US dollar exchange rate (Bruno and Shin 2015) in helping explain the synchronicity of capital flows to emerging markets.

Despite continuation of the US monetary policy tightening that started at the end of 2015, an interesting feature of the global economic expansion of 2017 is that capital inflows to both emerging and frontier markets rose. Figure 2.9 (panel 1) shows that this was also the case for China, which experienced an increase in bank-related inflows (captured under “other investment”) and, to a lesser degree, in portfolio equity and debt inflows.

3 Frontier market economies are defined as World Economic Outlook low-income economies included in the Morgan Stanley Capital International Frontier Markets Index: Bangladesh, Benin, Burkina Faso, Côte d’Ivoire, Guinea-Bissau, Kenya, Mali, Niger, Senegal, Togo, and Vietnam.

A large part of capital inflow behavior in recent years has been related to unconventional monetary policy in the United States. Figure 2.10 (panel 1) illustrates that US unconventional monetary accommodation (as in an expanding Federal Reserve balance sheet) has underpinned a significant portion of portfolio inflows to emerging markets. Both elevated global risk appetite (proxied by low US VIX levels) and domestic pull factors explain the 2017 increase in capital inflows to emerging market economies. Overall, these model estimates suggest that the expected steady pace of Federal Reserve policy normalization over the next few years (both through balance sheet reduction and a rising federal funds rate) could reduce portfolio flows by a cumulative $75 billion by late 2019 (Figure 2.10, panel 2, left vertical axis).7 Most emerging market economies should be able to handle this reduction in inflows, given their enhanced resilience and stronger growth outlooks.

A rapid increase in investor risk aversion would, however, have a more severe impact on portfolio inflows and could prove more challenging, including for China—but especially so for countries with greater dependence on external financing.

The relative foreign exchange value of the US dollar is another important driver of global financial conditions. China has moved to managing its exchange rate against a basket of currencies, rather than against the US dollar alone, to dampen exposure to US dollar variability. Nonetheless, the US dollar exchange rate tends to have a substantial impact on capital inflows (see Bruno and Shin 2015; Hofmann, Shim, and Shin 2017), and the US dollars steady depreciation against most currencies from early 2017 to early 2018 (Figure 2.11, panel 1) has been one key driver of increasing capital inflows to emerging markets.

2 Swap-implied future inflation rate differentials.

This depreciation spell, which stopped only in early 2018, stood at odds with the traditional (uncovered) interest rate parity condition.8 Take the US dollar–euro relationship, for example. As indicated by the market’s expectations of future short-term interest rates (proxied by the yield differential of

Eurodollar-Euribor futures in panel 2 of Figure 2.11), the market by the start of 2018 had priced in faster US monetary tightening than the implied future interest rate differential path at the start of 2017. Similarly, the market also expected the future inflation differential between the euro area and the United States to narrow further relative to expectations of early 2017 (Figure 2.11, panel 3). Both forces should have put upward pressure on the dollar, contrary to the evolution that actually occurred in the foreign exchange market.

The dollar’s depreciating trend is reflected in foreign exchange futures market sentiment: speculative positions on the euro flipped from net short to net long after the euro began appreciating in early 2017, while the US dollar has been heavily shorted more recently. One possible explanation for the puzzling US dollar depreciation is that advanced-economy financial conditions have remained relatively loose, fueling capital outflows (and inflows to emerging market and frontier economies). Another potential explanation is that, given expected reductions in the Federal Reserve’s balance sheet and impending bigger fiscal deficits in the United States, a great deal of US dollar debt will have to be absorbed by markets in the coming years, weakening the currency, all else being equal.

More recently (especially since April 2018), the dollar has indeed shown more strength, as growth in the euro area and Japan has seemed to retreat from stronger rates in 2017. Nonetheless, as of the end of May 2018, the US dollar had only partially reversed its cumulative depreciation after early 2017, and markets’ speculative positioning on the currency remained net short—although at a lower level than at the end of 2017.

Sensitivity of Capital Inflows to the Global Financial Cycle

The US variables discussed in the previous section are often identified as key drivers of the global financial cycle (Cerutti, Claessens, and Rose 2017). The increased integration of China into international capital markets will likely increase its exposure to the global financial cycle, which, some have argued, could augment financial stability risks while weakening the scope for independent monetary policy (Rey 2016).

China’s sensitivity to the global financial cycle is currently lower than that of other countries in terms of portfolio flows, especially portfolio debt securities. As Figure 2.12 shows, based on the analysis of Cerutti, Claessens, and Puy (forthcoming), in China, only 5 percent of total variance in portfolio debt inflows is accounted for by a common factor empirically related to the global financial cycle. This is much lower than for the average Asian emerging market economy (18 percent) and for the average of all emerging market economies (13 percent). The finding is in line with the reality that foreign participation is simply not as large in China’s bond market as it is elsewhere.

Figure 2.12.Sensitivity to Emerging Market Common Factors, by Type of Capital Flow, 2001–15

In this context, it is likely that further liberalization in the bond market would probably elevate sensitivity to the global financial cycle. Using the estimated loading coefficient for the common factor estimated by Cerutti, Claessens, and Puy (forthcoming), along with countries’ exposures to global investors, one can visualize in Figure 2.13 (panel 1) how China’s low bond inflow sensitivity is related empirically to the relatively low participation of global investors. Based on this cross-country evidence, it is foreseen that further liberalization of the Chinese bond market will increase sensitivity to global developments, as has happened in other countries. This is less the case for equity inflows, where China ranks in the middle of the emerging market economy group (see Figure 2.13, panel 2).

1 A weight above (below) one implies that the country was over- (under-) represented in global investor flows relative to total balance of payment flows. Peru is an outlier in terms of exposure to global investors in equity markets because of the incorporation in offshore markets of Peru’s largest domestic bank holding company and a large Peruvian mining company.

Conclusions

Room remains substantial for further integration of China into the global bond market, which would advance the broader project of sustainably integrating the country into international trade and finance. However, this process will likely increase exposure to the global financial cycle.

This chapter concludes that, for monetary autonomy, the cost would not be large given China’s size and especially under a more flexible exchange rate framework than the current one, supported by a well-articulated inflation-targeting framework.9 For financial stability, however, work remains to be done, as both China’s government and the IMF recognize (IMF 2017b).

Other advantages, from a domestic Chinese perspective, include that an influx of foreign capital would help diversify funding and improve liquidity, maturities, and transparency in the local bond markets. Similarly, further geographical diversification by Chinese resident financial asset holders (including in the private sector) would improve domestic asset allocations.

From a global perspective and taking into account that China offers a potentially large pool of savings, better integration into the international bond market could promote a significantly more productive allocation of the world’s savings, to the benefit of lenders and borrowers alike.

SUN (2015) describes the recent reforms. Te inclusion of around 230 mainland-listed stocks in the MSCI index took effect on June 1, 2018. Initially, the share of Chinese A-shares amounted to about 0.7 percent of the MSCI index, with a future full inclusion weight of about 18 percent. Whereas Chinese bonds are not now included in any global index, if included, their index weight would be about one-third of the widely followed J.P. Morgan Emerging Markets Bond Index Global, according to the IMF’s April 2016 Global Financial Stability Report.

As in other countries, foreign investors could also increase exposure to a particular country through offshore markets. For China, this is especially the case through the offshore markets operating in Hong Kong SAR, where bonds can also be issued in renminbi—usually known as dim sum bonds (see Chapter 14). Nonetheless, the small foreign participation in the Chinese onshore bond market does not seem to be driven by the availability of bonds in these offshore markets. In addition to maturity considerations (that is, maturities are often shorter in offshore markets), the activity in these offshore markets is influenced by both the offshore issuance of bonds by Chinese companies that need to be authorized by the National Development and Reform Commission (China’s economic planning ministry and regulator for enterprise bonds), and net renminbi outflows from the mainland, which provide a large part of the liquidity and are also regulated from the mainland. Moreover, the launch of the Bond Connect program—which liberalizes some regulations by allowing institutional international investors to trade onshore bonds through Hong Kong SAR—has increased foreign holdings in onshore markets in 2018, according to Hong Kong Exchange (2018).

The May 2017 Research Report of the Hong Kong Exchange finds that foreign financial institutions tend predominantly to hold Chinese sovereign bonds and the most highly rated corporate bonds as part of their renminbi reserves because of China’s weak market infrastructure, particularly the rather low credibility of local credit rating agencies.

A forward foreign exchange contract is an obligation to purchase or sell a specifc currency on a future date for a fixed price set on the date of the contract. In the context of this chapter, while onshore forwards refer to contracts made in mainland China, offshore forwards cover contracts in international financial centers, such as Hong Kong SAR. A nondeliverable forward (NDF) is similar to a regular forward foreign exchange contract, except at maturity the NDF does not require physical delivery of currencies.

MA and McCauley (2014) also document that the renminbi is priced more cheaply onshore than offshore in the foreign exchange forward markets (as in Figure 2.8, as shown by the higher cost of hedging using NDFs compared with onshore forwards). They associate this phenomenon with an appreciation of the renminbi and net private capital inflow pressures whenever the capital account opens up in China. Their projections for net inflows contrast with both HE and others (2012) and Bayoumi and Ohnsorge (2013), who project large increases in gross external positions (both assets and liabilities), but with private assets increasing more than liabilities. Estimating the net impact of further financial market liberalization is beyond the objectives of the chapter and constitutes a very complex task, especially given that relationships estimated with historical data would not necessarily be good predictors of the final direction of capital flows after structural policy changes—which, in any case, will not necessarily be implemented all at once.

Absent counterparty risk, covered interest rate parity is a pure arbitrage relationship that links the premium of a currency’s forward over its spot exchange rate to its nominal interest rate advantage over foreign currency (see Cerutti, Obstfeld, and Zhou [2019] for more details).

As IMF (2017a) highlights, estimates for portfolio flows are obtained using a model adapted from Koepke (2014). Te model estimates the impact of external “push” and domestic “pull” variables on portfolio flows to emerging markets, consistent with the capital flows literature. Te dependent variable reflects monthly data from the Institute of International Finance on nonresident portfolio flows to emerging market economies (that is, foreign purchases of emerging market stocks and bonds). Independent variables aim to capture push factors and pull factors. Push variables include a proxy for global risk aversion (either the US corporate BBB spread over Treasuries or the USVIX), three-year-ahead expectations for the effective federal funds rate, and the change in assets held on the Federal Reserve’s balance sheet. Pull variables include an emerging market economic surprise index compiled by Citigroup and the Morgan Stanley Capital International Emerging Markets Index (MSCI).

The traditional (risk-neutral) uncovered interest rate parity formula can be written as follows:

in which an asterisk denotes a foreign variable; e is the current nominal exchange rate (expressed in units of domestic currency per foreign currency so that an increase in e represents a depreciation of domestic currency); i denotes a one-period nominal interest rate; π is an inflation rate; and q is the real exchange rate. As the future interest rate differential (the first term on the right) widens and future inflation-rate differentials (the second term on the right) narrow, theory predicts that the domestic currency should appreciate. Te only potential counteracting force in the equation is the long-term future real exchange rate (q¯t+T+1), which captures a broad range of factors, including future fiscal policy conditions. Of course, adding risk preimums to the aforementioned formula (to capture the failure of uncovered interest parity) would introduce an additional driver of the currency’s relative value.

The need for greater flexibility is often cited inside and outside of China, but much progress remains to be made. Transition could proceed along broad lines as laid out in Obstfeld (2007), with due attention to the need to refine an appropriate inflation-targeting framework, as discussed in several of the essays in AI and Schipke (2017).
