Bank of China (Hong Kong), the city's designated clearing bank for the offshore yuan, is set to become the first offshore clearing institution to borrow directly in mainland China's interbank market. The lender has received a quota from the People's Bank of China (PBOC) to issue onshore negotiable certificates of deposit (NCDs), a type of short-term funding instrument that banks sell to other financial institutions.
According to the bank, it plans to issue up to 22.2 billion yuan (about $3.3 billion) of these NCDs during 2026, with the exact size and maturity of each deal to be determined at the time of issuance. This marks a notable step in the gradual integration of Hong Kong's offshore yuan market with the mainland's onshore financial system.
What are NCDs and why do they matter?
Negotiable certificates of deposit are essentially short-term IOUs that banks issue to raise funds from other banks and institutional investors. They are a common tool in China's interbank market, where banks lend to one another to manage daily liquidity. Unlike traditional deposits, NCDs can be traded on the secondary market before they mature, making them flexible for both issuers and buyers.
For Bank of China (Hong Kong), gaining access to this market means it can tap a deep pool of yuan liquidity directly on the mainland. Previously, the bank would have relied on offshore yuan deposits or swap arrangements to fund its yuan operations. The new quota gives it a more direct and potentially cheaper source of funding, depending on prevailing interest rates.
The timing is significant because funding costs can diverge between the onshore and offshore yuan markets. When onshore rates are lower than offshore rates, issuing NCDs on the mainland could reduce the bank's funding expenses. Conversely, if onshore rates rise, the bank can simply choose not to issue, keeping its options open.
A bridge between two yuan markets
Hong Kong is the largest offshore yuan hub, and Bank of China (Hong Kong) has long served as the clearing bank for yuan transactions in the city. That role involves settling trades and providing liquidity for the offshore yuan market, which operates outside mainland China's capital controls.
By allowing an offshore clearing bank to issue onshore NCDs, the PBOC is effectively building another bridge between the two markets. This could help align interest rates and reduce arbitrage opportunities, while also giving mainland investors access to paper issued by a well-known offshore institution.
The move comes amid broader efforts by Beijing to internationalise the yuan and open up its financial markets. In recent years, regulators have expanded channels for foreign investors to buy Chinese bonds and for offshore institutions to raise funds on the mainland. This NCD quota fits that pattern, though it is still a relatively small step in the grand scheme of China's capital account liberalisation.
What it means for investors
For everyday investors, the direct impact is likely to be limited, but the development is worth watching for a few reasons. First, it signals that China is continuing to open its financial system, which could support the yuan's international use over time. A more integrated yuan market may also reduce the gap between onshore and offshore exchange rates, which can affect currency traders and companies doing business across the border.
Second, the move could influence funding conditions for Chinese banks. If offshore banks like Bank of China (Hong Kong) become more active in the onshore NCD market, it could add supply to that market, potentially putting mild downward pressure on onshore interbank rates. That would be a subtle but positive factor for borrowers in China, including corporations and property developers.
Third, the development is a reminder that Hong Kong's role as a financial bridge remains central to China's plans, even as the city faces competition from other offshore yuan centres. For investors with exposure to Hong Kong banks or Chinese financials, this is a modest sign that the regulatory environment is supportive of cross-border activity.
That said, the quota of 22.2 billion yuan is small relative to the size of China's interbank market, which sees trillions of yuan in NCD issuance each year. So the immediate market impact should not be overstated. The significance is more structural: it sets a precedent that could be expanded in the future.
Investors should also keep an eye on how this fits with other signals from China's economy. Recent data has shown mixed inflation figures and strong but uneven bank lending, suggesting the central bank is trying to support growth without overstimulating. The NCD quota is a small part of that broader policy toolkit.
For those tracking the yuan's internationalisation, this is a quiet but meaningful step. It gives offshore institutions a new way to access onshore liquidity, which could make the yuan more attractive for trade and investment. Over time, that could have implications for currency markets and for companies that operate across the border.
As with any regulatory change, the details matter. The bank will issue NCDs deal by deal, so the actual amounts and maturities will vary. Investors who want to gauge the impact should watch the rates at which these NCDs are issued, as they will reveal how much the bank values this new funding channel.
