Liquidity and correlation in the Chinese credit market

Corporate earnings surprise

  • The Chinese credit market is now the second-largest in the world, with 38 trillion Chinese yuan (USD 5.5 trillion).
  • However, foreign ownership of Chinese credit has remained extremely modest, with overseas bondholders owning less than 1% of the market.
  • An anomaly exists in how credit from the same issuer trades in the China onshore and U.S. markets.

China’s stock market has drawn huge attention from global investors, especially as China A shares have been added to leading equity indexes.But the same cannot be said for the country’s 38 trillion CNY (USD 5.5 trillion) credit market, now the second-largest in the world.2 Despite the market’s overall size, foreign investor participation remains miniscule, with overseas bondholders accounting for less than 1% of the total holdings.3


“Large” does not mean “liquid”

Following the Global Financial Crisis, Beijing launched an economic stimulus program that encouraged many state-owned enterprises to borrow money to finance growth.4 At the same time, China loosened credit requirements as part of an effort to promote direct financing, providing additional stimulus to the market.5 When the People’s Bank of China cut rates and reserve requirements in 2015,6 debt growth accelerated further, as can be seen in the exhibit below.

As noted, non-domestic investors hold a tiny proportion of Chinese credit (compared to 30% in the U.S.).2 Moreover, these investors have raised concerns about the relatively poor liquidity of this market, as most bonds are owned by a small group of local institutions and are held until maturity.7

An idiosyncratic market

Chinese corporate bonds have shown low correlation with both emerging- and developed-market credit, given the idiosyncratic nature of China’s state-driven macroeconomic policies and the low participation of foreign investors in the market. We can see Chinese credit’s low correlation with other global credits in the matrix below.

There also is an anomaly in how credit from the same issuer trades in the China onshore and U.S. markets. Theoretically, these bonds should trade with high correlations, as both bonds face equal credit risk. This is true for markets such as Canada, Europe and the U.S., where the average spread correlation of debt of an issuer trading across markets is around 60%-70%. In contrast, bonds of similar maturities from Chinese companies that issue debt denominated in both the Chinese renminbi and the U.S. dollar exhibited much lower correlations – close to zero and sometimes negative – as we can see in the exhibit below.

Data sampled from Jan. 1, 2016 through April 26, 2019 with weekly frequency for 15 Chinese, 47 Canadian and 175 European Union issuers. We also note that the hypothetical portfolios of renminbi and U.S. bonds for the Chinese issuers exhibited similar average currency-hedged monthly returns.


An evolving bond segment

The characteristics of China credit have been related to China’s unique macroeconomic policies and the composition of market participants. As China’s regulators continue to make their equity and bond markets more accessible to international investors, these characteristics may continue to evolve.8 Such moves, including the opening of the related futures market,9 may attract participation from more international investors, potentially leading to better liquidity and changes in the market’s correlation structure.
