In the global foreign exchange market, traders often encounter terms like Renminbi (RMB), Onshore Renminbi (CNY), and Offshore Renminbi (CNH). While they seem to refer to the same currency, they exhibit distinctly different characteristics in actual trading, often confusing investors new to this field. In fact, this unique “one currency, two markets” structure is not an accidental technical difference but reflects a well-thought-out national economic strategy. Understanding the relationship between these three, especially the nature of Offshore Renminbi (CNH), is essential knowledge for any investor wishing to trade related currency pairs.
Renminbi (RMB) is the official name of China’s currency, much like Sterling is for the United Kingdom. CNY and CNH, on the other hand, are the two currency codes for its trading in different markets, similar to how a stock has different ticker symbols on various exchanges. CNY represents the Renminbi traded within mainland China (the onshore market), while CNH represents the Renminbi traded outside mainland China (the offshore market). For global traders, the Renminbi you see and can freely buy and sell on forex platforms is precisely the Offshore Renminbi (CNH).
To truly understand the Offshore Renminbi (CNH) you trade in the market today, we must look back at the historical context of its birth. The emergence of CNH was not a sudden market evolution but a carefully planned chapter in China’s economic development blueprint. This history not only reveals the fundamental purpose of establishing the offshore market but also provides a crucial background for interpreting its exchange rate fluctuations today.
The seeds of the offshore Renminbi market were sown in the early 21st century. With the rise of the Chinese economy and its growing importance in global trade, promoting the international use of the Renminbi became a strategic goal. However, fully opening the domestic capital account could trigger financial risks, which policymakers at the time sought to avoid at all costs. Thus, a solution was born that could both promote the Renminbi globally and effectively insulate it from risk.
This process was gradual. The first step began in 2003, when the People’s Bank of China (PBoC) started providing RMB clearing services for local banks in Hong Kong, opening a small window for the currency to be circulated and settled offshore. Hong Kong, with its unique status as an international financial center and mature financial infrastructure, naturally became the chosen location for this historic experiment.
A key turning point occurred in 2010. That year, the PBoC and the Hong Kong Monetary Authority (HKMA) signed a series of agreements allowing participating banks in Hong Kong to conduct RMB transactions directly with each other (“matching”), without needing to go through a designated clearing bank. This move marked the official birth of an offshore RMB exchange rate independent of mainland China, determined by market supply and demand—the CNH. This “sandbox” innovation allowed China to test the waters of RMB internationalization, observe the global market’s reaction to the currency, and gradually build the relevant financial infrastructure without fully opening its domestic capital market, thereby accumulating valuable experience for larger-scale opening in the future.
With the promotion of cross-border trade settlement in RMB, a large pool of offshore RMB funds gradually formed in Hong Kong. However, a new problem arose: these funds parked offshore lacked effective investment channels, which greatly limited foreign investors’ willingness to hold Renminbi. To solve this, a series of RMB-denominated offshore financial products emerged, the most representative of which are the “Dim Sum Bonds”.
Dim Sum bonds are bonds issued in Hong Kong and denominated in Renminbi. The evocative name, on one hand, points to its place of origin, Hong Kong, and on the other, reflects its relatively small scale in the global bond market initially.
The first batch of Dim Sum bonds was issued in 2007 by Chinese financial institutions such as the China Development Bank. Although the market size was small at first, it set a precedent, providing the first major investment option for offshore RMB other than bank deposits.
The real tipping point for the market came in 2010, when the American fast-food giant McDonald’s became the first non-Chinese multinational corporation to issue Dim Sum bonds, a move that drew widespread attention from the global market. This signaled that the appeal of the offshore RMB market had expanded beyond Chinese institutions and was beginning to be recognized by international capital. The success of Dim Sum bonds greatly enriched the offshore RMB ecosystem. It not only solved the investment outlet problem for offshore RMB but also helped establish an offshore RMB yield curve, providing a benchmark for pricing more complex financial products. From then on, more financial innovations, including RMB-denominated funds, insurance products, and derivatives, could be developed, collectively injecting vitality and depth into the offshore RMB market, transforming it from a simple trade settlement tool into a more complete financial market with investment and financing functions.
Although Offshore RMB (CNH) and Onshore RMB (CNY) both originate from the same currency—the Renminbi—and theoretically follow a 1:1 exchange ratio, their behavior in the global foreign exchange market is worlds apart. For traders, clearly identifying and understanding these differences is crucial, as it directly affects market analysis, risk assessment, and trading decisions.
The most fundamental difference lies in the regulatory frameworks and market positioning behind them. Onshore RMB (CNY) is the legal tender circulating within mainland China, operating under the strict supervision of the People’s Bank of China (PBoC) and the State Administration of Foreign Exchange (SAFE). The primary function of this market is to serve China’s domestic economic activities and trade settlement, with stability being the top policy consideration. Therefore, all cross-border flows and exchanges related to CNY are subject to strict capital controls.
In stark contrast, Offshore RMB (CNH) is primarily traded in international financial centers outside mainland China, such as Hong Kong, Singapore, and London. The very purpose of CNH’s creation was to promote the use of the Renminbi in international trade and investment, so it was designed from the outset to have greater freedom. Although regulatory bodies in offshore centers like the Hong Kong Monetary Authority (HKMA) oversee the market, the exchange rate and liquidity of CNH are primarily determined by the supply and demand of global market participants, with far less direct intervention than CNY. This regulatory difference defines CNY as a relatively closed and stable “policy-driven market,” while CNH is a more open and volatile “market-driven market.”
The difference in regulatory systems directly leads to a “dual-track” system for their exchange rate formation mechanisms, which is the most critical technical difference for traders to be aware of.
CNY operates under a “managed floating exchange rate system.” Specifically, each morning on trading days, the PBoC announces an official “central parity rate” based on the previous day’s closing price and changes in a basket of currencies. In the subsequent trading, the spot exchange rate of CNY against the US dollar can only fluctuate within a narrow band of ±2% around this central parity rate. If the rate touches the edge of this band, the central bank has the authority to intervene to maintain stability. This mechanism is designed to prevent drastic exchange rate fluctuations and ensure domestic economic and financial stability.
In contrast, the exchange rate mechanism for CNH is a “market-driven free float.” Its price is determined entirely by the trading activities of global buyers and sellers in the offshore market, with no daily central parity rate limit and no explicit fluctuation band. Because of this, the CNH exchange rate can reflect changes in international market sentiment regarding China’s economic outlook, policy expectations, and global risk appetite more quickly and sensitively. This also explains why, although the face value of CNY and CNH is 1:1, they have different exchange rate quotes when converted to US dollars or other foreign currencies, leading to a spread between the two.
From a practical application perspective, the differences in convertibility and liquidity have the most direct impact on businesses and investors.
CNY is subject to strict capital controls, making its convertibility relatively limited. This means that freely converting CNY into foreign currency and remitting it abroad requires approval and is subject to quotas. For foreign companies with operations in mainland China, the payments they receive are in CNY, but if they wish to use these funds for investment or payment outside of mainland China, they must first convert them into CNH or another foreign currency, a process that is regulated.
On the other hand, as an offshore currency, the core feature of CNH is its free convertibility. In offshore markets like Hong Kong, any individual or institution holding CNH can convert it into US dollars, euros, or any other major currency without restrictions, and freely transfer and use it globally. This high degree of freedom makes CNH the primary tool for international investors to trade on China-related themes, allocate assets, and hedge against RMB exchange rate risk. At the same time, due to the broad participation of global players, the CNH market typically has deeper liquidity and is a better reflection of international capital flows, although this also means its volatility may be greater.
To summarize these core differences more intuitively, the following table provides a clear comparison:
| Feature | Onshore RMB (CNY) | Offshore RMB (CNH) |
| Trading Location | Mainland China | Outside mainland China (e.g., Hong Kong, Singapore, London) |
| Regulatory Body | People’s Bank of China (PBoC) / State Administration of Foreign Exchange (SAFE) | Primarily market-driven, influenced by offshore centers like the HKMA |
| Exchange Rate Mechanism | Managed float (fluctuates within a ±2% band around the daily central parity rate) | Free float (determined by market supply and demand) |
| Primary Use | Domestic trade and transactions | International trade, investment, and financial transactions |
| Convertibility | Subject to capital controls, limited convertibility | Freely convertible |
Since Offshore RMB (CNH) is a market-driven currency, its exchange rate value is like a complex tapestry woven from economic data, policy signals, and global sentiment. For traders aiming to predict market direction, understanding these intertwined threads is essential.
As a window to the Chinese economy for the world, the CNH exchange rate trend is largely a direct reflection of the health of China’s macroeconomy. International investors closely monitor key economic indicators released by China and use them as a basis for judging the intrinsic value of the Renminbi.

In addition to quantifiable economic data, several intangible yet highly influential factors also shape the trend of CNH. It’s a continuous game played between policy intentions and market sentiment.
The dynamic relationship between CNH and CNY is itself an important market indicator. The exchange rate spread between the two is a key window for observing capital flow pressures and market sentiment.
Under normal circumstances, this spread remains within a relatively small range. However, when the market experiences sharp volatility, the spread can widen significantly. For example, when CNH depreciates much more than CNY (i.e., the CNH/CNY spread is negative and widening), it often indicates strong capital outflow pressure or rising negative sentiment towards China in the international market. The reverse is also true.
The existence of this spread also gives rise to arbitrage trading. When the spread is large enough, traders can earn risk-free profits by buying RMB in the market where it is cheaper and simultaneously selling it in the market where it is more expensive. This arbitrage activity itself forms a market correction mechanism, as buying the cheaper currency pushes its price up, and selling the more expensive one pushes its price down, thus helping to narrow the spread between the two. Furthermore, the overall risk appetite of the global market (Risk-on/Risk-off) also affects CNH, as it is seen to some extent as a proxy for emerging market currencies. A rise in global risk aversion often works against it. Therefore, analyzing CNH requires a dual perspective: one must focus on traditional macroeconomic fundamentals while also deeply understanding its unique structure linked to the onshore market and its high sensitivity to policy signals.
Understanding the significance of Offshore RMB (CNH) is not just about seizing current trading opportunities; it is about gaining insight into an ongoing, far-reaching shift in the global economic landscape—the internationalization of the Renminbi. The future of CNH is closely linked to China’s position and ambitions on the global economic stage. It is both a pioneer in this grand process and an epitome of the challenges it faces.
From its inception, CNH has played the dual role of a “testbed” and a “firewall” for RMB internationalization. It has provided China with a steady path to gradually enhance the role of the Renminbi in global trade settlement, investment, financing, and as a reserve currency, without having to fully open its domestic capital account and risk potential financial shocks. Through the offshore center of Hong Kong, China can test the global market’s acceptance of RMB-denominated assets, improve its cross-border payment systems, and accumulate experience in managing an open economy.
In recent years, RMB internationalization has made significant progress. According to data from the Society for Worldwide Interbank Financial Telecommunication (SWIFT), the Renminbi has firmly established itself as the fourth largest payment currency globally. At the same time, the People’s Bank of China has signed bilateral local currency swap agreements with central banks in dozens of countries and regions, with a total value reaching trillions of RMB. This provides liquidity support for bilateral trade and reduces reliance on a single third-party currency.
However, the road ahead is still full of challenges. The core bottleneck for RMB internationalization lies in its true convertibility and global trust as a store of value. Some recent cases highlight this issue. For instance, some countries have accepted Renminbi as a trade settlement currency through bilateral agreements but then faced difficulties in effectively utilizing these RMB assets or converting them into other hard currencies or assets. There are reports that some countries, after receiving Renminbi, have chosen to convert it into gold at the Shanghai Gold Exchange. This reflects that while the transactional function of the Renminbi is expanding, its appeal as a long-term store of value is still being tested by the market. This reveals a profound contradiction: on one hand, the goal is to promote the widespread use of the Renminbi, and on the other, there is a need to manage the potential pressure on foreign exchange reserves that this might cause.
Looking ahead, the development of new technologies such as the digital RMB (e-CNY) may provide new solutions for cross-border payments, further supplementing and evolving the existing CNH system. But ultimately, the success of RMB internationalization will depend on whether it can shift from a “push model,” driven primarily by bilateral agreements and policy promotion, to a “pull model,” where it is actively chosen by the global market for its intrinsic stability, liquidity, and ease of use. The key to this transformation lies not only in financial technology innovation but also in building deep, widely recognized international trust.
Offshore RMB (CNH) is not merely a simple mirror image of Onshore RMB (CNY). It is a product carefully designed in the era of globalization to achieve the grand strategic goal of RMB internationalization. CNH is the free, market-priced version of the Renminbi for the international market, while CNY is the strictly regulated onshore version serving the domestic economy. This unique “one currency, two markets” structure means that the CNH exchange rate is influenced by a complex mix of factors, including economic fundamentals, policy expectations, international sentiment, and its linkage with the onshore market.
For traders in the ever-changing global financial market, navigating a currency as unique as CNH presents both challenges and opportunities. Success depends not just on finding a trading account, but on having a partner who can provide comprehensive support.

Theoretically, the exchange ratio between CNH and CNY is 1:1. However, converting Onshore RMB (CNY) to Offshore RMB (CNH) for use abroad is subject to capital controls. Although their face values are the same, their exchange rates against other foreign currencies (like the US dollar) will differ because CNH is freely priced by the market, while CNY is managed by the People’s Bank of China.
These are two different concepts. CNH is the market-based, freely traded version of the physical Renminbi outside mainland China. In contrast, the digital RMB (e-CNY) is the digital form of China’s legal tender, centrally managed by the central bank and primarily designed for domestic retail payment needs. Currently, e-CNY is mainly being piloted domestically. Its future cross-border applications may become part of the RMB internationalization strategy, supplementing or evolving the existing CNH system.
