“Dim Sum Bonds Join the Global Collateral Pool”: Chinese Government Bonds Enter the Heart of London’s Derivatives Market, Giving Renminbi Internationalization Fresh Momentum

LCH Adds Offshore Renminbi-Denominated Chinese Government Bonds to Eligible Collateral
Trade Settlement Lays the Foundation for Renminbi Internationalization
Renminbi Financial Ecosystem Expands into Global Capital-Market Infrastructure

London’s core clearing infrastructure has added offshore renminbi-denominated Chinese government bonds to its collateral pool. As a result, offshore renminbi government bonds, already used for bond investment and trade settlement, can now serve as margin collateral in derivatives transactions. Although restrictions remain on eligible assets and contribution limits, the international utility of renminbi assets is expanding rapidly amid rising Chinese government bond issuance, renminbi appreciation and a resurgence of foreign capital inflows into the country’s bond market. The focus of renminbi internationalization is also shifting from trade settlement toward global capital-market infrastructure, including derivatives clearing and collateral management.

Renminbi Government Bonds Enter the International Clearing Market

According to Hong Kong’s South China Morning Post on July 15, the London Clearing House, or LCH, a core clearing institution under the London Stock Exchange Group, recently launched a new framework recognizing offshore renminbi-denominated Chinese government bonds as eligible non-cash collateral. Global investors trading derivatives through LCH can now use dim sum bonds—renminbi-denominated bonds issued in Hong Kong’s bond market—as margin collateral alongside U.S. Treasuries and euro-denominated bonds. The expansion of offshore renminbi assets into the international derivatives clearing market is being hailed as a major milestone in the currency’s internationalization.

The introduction of the new collateral framework was spearheaded by Bank of China, the country’s largest state-owned commercial bank and one of its most internationally connected lenders. Linking overseas operations including BOC Hong Kong and its London and Hong Kong branches, the bank processed the first transaction using dim sum bonds as collateral on July 7. BOC Hong Kong coordinated the transaction structure and procedures that allowed dim sum bonds held by multiple multinational institutional investors to be deposited into LCH clearing accounts. Custody and settlement of the bonds were handled through global securities depository Euroclear Bank.

The scope of the measure is clearly defined. Eligible assets are limited to CNH-denominated sovereign bonds issued offshore by the Chinese government. Ordinary dim sum bonds issued by banks and corporations, as well as CNY-denominated government bonds traded in mainland China, are excluded. Strict restrictions also apply to collateral contributions. CNH-denominated Chinese government bonds may be submitted only on a bilateral basis, while triparty arrangements involving multiple institutions in collateral management are not permitted. For Chinese clearing members, contributions are capped at the lower of 25% of initial margin or $100 million. For non-Chinese members, the ceiling is the lower of 25% or $250 million.

Before the measure was introduced, Bank of China’s London branch, the United Kingdom’s official renminbi clearing bank, established a funding pipeline for dedicated renminbi clearing accounts. It also created an operating framework linking China’s Cross-Border Interbank Payment System, or CIPS, with the United Kingdom’s Clearing House Automated Payment System, or CHAPS. This has provided the clearing and settlement infrastructure needed to connect liquidity in the British financial market directly with offshore renminbi assets. Patrick Wu, co-head of trading for Asia-Pacific and the Middle East at global investment bank Crédit Agricole CIB, said in an official LSEG statement that the measure represented “the most emblematic evolution demonstrating the deep integration of China’s high-quality assets into world-class international financial infrastructure,” adding that it would “provide powerful diversification in how multinational investors across Asia-Pacific conduct global risk management and post-trade financial settlement.”

Clearing LCH’s Formidable Collateral Threshold

Major Western clearing houses have traditionally operated eligible-collateral frameworks centered on U.S. Treasuries and the sovereign debt of leading European economies. LCH’s collateral threshold has been particularly demanding. When its predecessor, LCH.Clearnet, permitted gold bullion to be used as margin collateral in 2011, it limited the scope of the measure pending final regulatory approval and established separate risk-management standards reflecting price volatility and liquidation capacity. It continues to apply differentiated haircuts based on the issuer, maturity, denomination and market liquidity of government bonds.

Consequently, global investors holding highly rated renminbi assets were unable to use them as margin in international derivatives transactions and had to secure additional collateral, incurring higher funding costs and liquidity burdens in the process. LCH recognized Chinese government bonds issued in dollars and euros as eligible collateral in May last year. Its latest decision to extend eligibility to offshore renminbi-denominated dim sum bonds is expected to further enhance the liquidity and utility of renminbi assets.

The significance of the decision is amplified by LCH’s position as a core pillar of the global derivatives clearing market. According to LSEG, SwapClear, LCH’s interest-rate swap clearing division, provides access to a liquidity pool covering 95% of the standardized over-the-counter interest-rate swap market. It has cleared more than 65 million interest-rate swaps since 1999, with cumulative compressed notional principal exceeding $7 quadrillion. As the platform handles interest-rate products in 28 currencies, including the dollar, euro and pound, LCH’s collateral standards have far-reaching implications for margin management across global financial institutions.

LCH’s market position was also underscored by the dispute over financial sovereignty between the United Kingdom and the European Union following Brexit. Concerned that excessive reliance by European financial institutions on London’s clearing infrastructure could undermine financial stability and supervisory authority, the EU introduced the third iteration of the European Market Infrastructure Regulation, or EMIR 3. At the same time, it extended recognition of the equivalence of British central counterparties through June 2028 to prevent market disruption. This explains why the location of derivatives clearing, the currencies handled and the scope of eligible collateral are treated as matters of regulatory authority and financial sovereignty.

LCH’s decision to accept the bonds as collateral immediately translated into actual transactions. Bank of China’s Hong Kong operation and London branch deposited CNH-denominated Chinese government bonds into LCH accounts and supported collateral contributions by clearing clients including China Minsheng Bank. HSBC, Standard Chartered, DBS and Crédit Agricole also participated in the new collateral framework or expressed their willingness to support it. The emergence of operational cases immediately after the regulatory change indicates that both holdings of offshore renminbi government bonds and demand for their use as collateral have already reached a meaningful scale.

Renminbi Demand Rises Amid Dollar Uncertainty

The rapid expansion of the renminbi bond market lies behind this growing demand for collateral. According to the Financial Times, panda bonds—renminbi-denominated bonds issued in mainland China by foreign institutions—totaled $20.1 billion between January and May this year, up 90% from the same period a year earlier. While yields on China’s 10-year government bonds remained at around 1.7%, their U.S. counterparts held near 4.4%, driving stronger demand among global companies and foreign governments for renminbi funding.

Dim sum bond issuance had also reached $44 billion by late April, more than double the level recorded during the same period last year. Issuance arranged by U.S. banks climbed to a record $7 billion, with Goldman Sachs accounting for $4.7 billion. Goldman Sachs swapped the renminbi proceeds into dollars, hedged the currency risk and deployed the funds across multiple business divisions. Renminbi bonds are therefore evolving beyond a financing instrument confined to China-related operations and are increasingly being used to lower funding costs for global financial institutions.

Renminbi adoption has been particularly rapid in countries exposed to Western sanctions. The Russian government issued its first renminbi-denominated sovereign bonds last December, raising $2.8 billion. More than half of the issuance was purchased by Russian banks that had accumulated renminbi assets through trade with China. Demand among trading companies and financial institutions for China’s cross-border renminbi payment network, CIPS, has also reportedly increased since the outbreak of the war with Iran.

The renminbi’s relative stability has also supported investment demand. The currency appreciated 4.4% against the dollar last year and traded at roughly $0.148 on July 15, representing a gain of about 3.3% since the beginning of this year. International credit rating agency Fitch expects the renminbi to appreciate to approximately $0.149 by year-end, citing China’s substantial current-account surplus, a weaker dollar and the People’s Bank of China’s exchange-rate management stance. As uncertainty surrounding U.S. monetary and fiscal policy intensifies dollar volatility, the renminbi’s comparatively narrow trading range is helping reduce investors’ exposure to foreign-exchange losses.

The relative price stability of Chinese government bonds is also drawing foreign capital back into the market. According to the People’s Bank of China’s Shanghai headquarters, foreign institutions’ holdings of bonds in China’s interbank market increased from $460.8 billion in April to $475 billion in May. This marked the first net foreign purchase of China’s onshore renminbi bonds in 13 months, dating back to April last year. Over the same period, yields on major government bonds in the United States, United Kingdom, eurozone and Japan rose by between 0.35 and 0.60 percentage points amid the energy shock triggered by the war with Iran, while volatility in China’s government bond market remained limited.

Foreign ownership has also remained substantial in the equity market. According to China’s State Administration of Foreign Exchange, foreign investors held $600 billion in Chinese equities at the end of the first quarter this year. The large-cap CSI 300 Index also gained approximately 11% in dollar terms during the first half, reflecting a recovery in investor sentiment toward Chinese assets. When bond-market stability coincides with renminbi appreciation, foreign investors can typically expect to capture both interest income and currency gains. The low yields on Chinese government bonds alone make it difficult for them to compete with higher-yielding U.S. Treasuries. However, if dollar weakness and renminbi appreciation persist, the gap in effective returns, including currency-hedging costs, will narrow. The comparatively stable performance of Chinese bond prices despite geopolitical shocks is also stimulating demand among global investors seeking greater risk diversification.
