China's bond market: scale and significance
China's bond market is the second largest in the world after the United States, with outstanding bonds exceeding RMB 150 trillion (approximately USD 21 trillion). It includes government bonds (treasury bonds and local government bonds), policy bank bonds (issued by China Development Bank and other policy banks), corporate bonds, and various specialized instruments. For global fixed income investors, China represents a significant and underweight allocation.
Historically, this market was closed to foreign investors. That changed gradually: in 2010, overseas institutions gained direct access to the interbank bond market; in 2017, Bond Connect launched, providing a streamlined channel through Hong Kong. Today, foreign investors can access China's bond market through multiple pathways, with Bond Connect being the most popular.
As of end-2023, foreign holdings of Chinese bonds reached approximately RMB 3.7 trillion, representing about 3% of the total market — far below the weight of China in global GDP or global bond indices. This underweight reflects historical access barriers, but also creates potential opportunity for investors willing to navigate the market.
What Bond Connect is and how it works
Bond Connect is a mutual market access scheme that allows investors from mainland China and overseas to trade in each other's bond markets through connection between mainland and Hong Kong financial infrastructure. Launched in July 2017, it operates in two directions:
Northbound Bond Connect allows overseas investors to invest in China's interbank bond market through Hong Kong. This is the primary channel for foreign fixed income investment in China. Investors trade through Hong Kong-based dealers, and the trade is settled through a connection between Hong Kong's Central Moneymarkets Unit (CMU) and mainland bond market infrastructure.
Southbound Bond Connect (launched September 2021) allows qualified mainland investors to invest in Hong Kong-listed bonds. This is the reverse direction and is primarily used by Chinese institutions seeking offshore fixed income exposure. It is not relevant to foreign investors but completes the two-way access framework.
The Bond Connect Company Limited (BCCL), a joint venture between Hong Kong Exchange and mainland institutions, operates the platform. As of 2024, over 1,100 foreign institutions had entered China's bond market through Bond Connect — more than 95% of all foreign participants.
Northbound Bond Connect: how foreign investors participate
For foreign investors, Northbound Bond Connect is the practical path to China's bond market. The mechanism works as follows:
Eligibility: Qualified foreign investors include: sovereign institutions (central banks, monetary authorities, sovereign wealth funds); financial institutions registered outside China (banks, insurers, securities firms, fund managers); and medium-to-long-term institutional investors (pension funds, charity funds). This is broadly similar to QFII eligibility.
Trading process: Investors place orders with eligible Hong Kong dealers. The dealers execute trades on the China Interbank Bond Market (CIBM) through the Bond Connect platform. Trade matching, confirmation, and settlement are handled through the connected infrastructure.
Settlement: Bond Connect uses a Delivery versus Payment (DvP) model. Settlement occurs through a link between Hong Kong's CMU and mainland settlement systems (Shanghai Clearing House and CCDC). The investor holds bonds in an account with the mainland depository, accessed through the Hong Kong infrastructure.
Custody: Foreign investors are not required to appoint a mainland custodian. The Hong Kong infrastructure provides custody services, simplifying operations. This was a key innovation of Bond Connect compared to earlier access methods.
What bonds are available through Bond Connect
Bond Connect provides access to the full range of instruments in China's interbank bond market:
| Bond Type | Issuer | Characteristics | Foreign Interest |
|---|---|---|---|
| Treasury bonds | Ministry of Finance | Sovereign credit; most liquid; benchmark yields | High |
| Policy bank bonds | CDB, ADBC, ExIm Bank | Quasi-sovereign; high credit quality; liquid | High |
| Local government bonds | Provincial governments | Varying credit; infrastructure funding | Medium |
| Corporate bonds | SOEs and private companies | Credit spread; varying quality | Medium |
| Medium-term notes (MTNs) | Corporate issuers | Shorter duration corporate paper | Medium |
| CDs (Negotiable certificates of deposit) | Commercial banks | Short-term money market | Lower |
Treasury bonds and policy bank bonds account for the majority of foreign holdings. These instruments offer relatively high yields for sovereign-grade credit, deep liquidity, and straightforward risk assessment.
Corporate bonds offer yield pickup but require credit analysis. Foreign investors have been cautious due to corporate governance concerns and the lack of transparent credit ratings in some cases. Investment-grade SOE bonds are the most common corporate allocation.
Yields and the investment case for Chinese bonds
China's bond yields have historically been higher than developed market equivalents, reflecting China's higher growth and interest rate environment.
Yield comparison (approximate, as of 2026):
| Instrument | Yield Range | Notes |
|---|---|---|
| China 10-year Treasury | 2.0-2.5% | Higher than US Treasuries at times; spread varies |
| China 10-year Policy Bank | 2.3-2.8% | Additional spread over treasuries |
| China Investment-Grade Corporate | 3.0-4.5% | Credit spread varies by issuer |
| US 10-year Treasury | 4.0-4.5% | Benchmark for comparison |
| German 10-year Bund | 2.0-2.5% | Lower than China on average |
| Japan 10-year JGB | 0.5-1.0% | Much lower than China |
The investment case for Chinese bonds includes: diversification (low correlation with developed market bonds); yield pickup over some developed markets; and RMB exposure for investors bullish on the currency.
The risks include: currency volatility (RMB has depreciated against USD in recent years); liquidity (Chinese bond liquidity can be lower than developed markets); credit risk (especially for corporate bonds); and regulatory risk (though Bond Connect has been stable).
Index inclusion and passive flows
China's inclusion in global bond indices has driven significant passive investment flows into the market.
Major index inclusions:
- Bloomberg Global Aggregate Index: China included in 2019, with phased weight increase through 2020. Chinese government and policy bank bonds represent approximately 6% of the index.
- JP Morgan Government Bond Index-Emerging Markets (GBI-EM): China included in 2020 with 10% weight, gradually increased to 10% maximum weighting.
- FTSE World Government Bond Index (WGBI): China included starting October 2021, with phased implementation. Full weight of approximately 5-6%.
Index inclusion means that passive funds tracking these indices automatically allocate to Chinese bonds. This has brought tens of billions of dollars of foreign investment into China's bond market — much of it through Bond Connect. For active investors, understanding index flows is important: index inclusion events can affect bond prices and liquidity.
New developments: repo and derivatives
Bond Connect continues to evolve, with new functionality added to support investor needs.
Offshore repo trading: In February 2025, the National Interbank Funding Center announced the launch of offshore bond repurchase trading services under Bond Connect. This allows foreign investors to use their Chinese bond holdings as collateral for repo financing — improving liquidity management and capital efficiency.
Swap Connect: Launched in 2023, Swap Connect allows foreign investors to access China's interest rate swap market for hedging. This is particularly relevant for investors with large bond positions who want to manage interest rate risk.
These developments matter because they address practical investor needs. The original Bond Connect allowed bond purchase, but not financing or hedging. Adding repo and swaps makes the platform more useful for institutional portfolio management.
Operational considerations for Bond Connect investors
Institutions considering Bond Connect should plan for several operational aspects:
Dealer selection: Trade through Hong Kong dealers approved for Bond Connect. Major global banks and Chinese banks' Hong Kong branches offer these services. Compare execution quality, research coverage, and fees.
Account opening: Work with your dealer to open the necessary accounts with Hong Kong infrastructure (CMU) and establish links to mainland depositories. The dealer guides this process.
FX management: Bond Connect trades are settled in RMB. If your base currency is USD or another currency, you will need FX conversion. Some dealers offer integrated FX services; alternatively, use external FX providers.
Compliance and reporting: While Bond Connect has simplified access, institutions remain subject to regulatory reporting in their home jurisdictions. Understand your compliance obligations for foreign bond holdings.
Tax: Interest income from Chinese bonds is subject to withholding tax (typically 10% for treaty countries, though enforcement has varied). Work with tax advisers to understand your obligations.
Should you invest in Chinese bonds?
The decision to allocate to Chinese bonds depends on your investment mandate, risk tolerance, and existing portfolio.
Consider allocating if: You want diversification from developed market bonds; you seek yield pickup over developed market sovereigns; you have a strategic allocation to emerging markets and China is underrepresented; you want RMB exposure as a currency position.
Be cautious if: Your mandate limits currency risk and RMB volatility is problematic; you need high liquidity that Chinese bonds may not always provide; you are concerned about geopolitical risks affecting Chinese assets; your operational infrastructure doesn't support Chinese market access.
For most institutional portfolios, a modest allocation to Chinese government and policy bank bonds — perhaps 2-5% of the fixed income allocation — is reasonable for diversification. Larger allocations require stronger conviction on RMB and Chinese credit.
