CNY and CNH are two tickers for the same Chinese currency, the renminbi, trading in two separate markets with different rules. CNY is the onshore rate inside mainland China, kept on a short leash by the People’s Bank of China. CNH is the offshore rate that trades freely in Hong Kong, Singapore, London, and other financial centers. Because the two markets operate under different rules, the same yuan can carry two slightly different prices at the same moment, and the gap between them has become one of the most watched signals in global finance.
The Onshore Rate: How CNY Is Controlled
Every trading morning, the People’s Bank of China publishes a midpoint fixing rate for the yuan against the U.S. dollar. Roughly 35 designated market-maker banks submit price quotes, and the central bank sets the day’s reference point using those submissions along with movements in a basket of major currencies.1CME Group.

Once the midpoint is out, onshore trading can only move within a band of 2% above or below that number. If the price drifts toward either edge, state-owned banks typically step in to nudge it back toward the center. The arrangement gives importers, exporters, and manufacturers a predictable rate while letting Beijing signal its policy intentions through the daily fix. A surprisingly strong or weak fixing is one of the most closely parsed data points in currency markets, because it reveals how much depreciation or appreciation the central bank is willing to tolerate.
The Offshore Rate: How CNH Floats
Outside mainland China, the renminbi trades as CNH and behaves more like a conventional floating currency. The offshore market traces back to 2003, when Hong Kong first built settlement infrastructure for it, though active trading didn’t really take off until September 2010. Since then it has spread to more than two dozen financial centers, including Singapore, London, Frankfurt, and Luxembourg.2CME Group. Offshore Chinese Renminbi (CNH) Futures Quotes
No daily fixing constrains CNH. The price moves around the clock on global supply and demand, interest rate differentials, investor sentiment, and geopolitical events. When something unsettles international markets, CNH reacts immediately while CNY may barely budge thanks to the trading band. That responsiveness makes CNH the preferred instrument for multinationals hedging currency risk and for hedge funds taking a position on China.
What the CNY–CNH Spread Tells You
Because the same currency trades under two different sets of rules, the onshore and offshore prices rarely match exactly. During calm periods the two track each other closely. During stress, the gap widens, and the direction of the gap carries meaning.
When CNH trades at a discount to CNY, meaning the offshore price implies a weaker yuan, it usually reflects capital outflow pressure. International investors are betting on depreciation, or money is leaving China faster than it’s arriving. The wider the discount, the more stress the market perceives. A CNH premium over CNY points the other way: strong foreign demand for the currency, often driven by healthy trade flows or an expectation that Beijing will tolerate appreciation. The spread blows out during episodes of policy uncertainty, trade tensions, or sudden shifts in U.S. interest rates, which is why traders, corporate treasurers, and central bankers watch it as a real-time read on China’s financial health.
Why the Two Markets Stay Separate
The wall between CNY and CNH exists because of capital controls, and those controls are deliberate. The State Administration of Foreign Exchange, known as SAFE, enforces strict rules on moving money across the border, requiring documentation of a legitimate trade or investment purpose before approving conversions between onshore and offshore funds.3Trade Commissioner Service. Foreign Exchange Controls in China
Individual Chinese citizens face an annual limit equivalent to $50,000 in foreign exchange. Anything beyond that requires a SAFE permit. On the institutional side, the Qualified Domestic Institutional Investor program lets selected financial institutions invest abroad, but only within assigned quotas. In mid-2025, SAFE granted $3.08 billion in new QDII quotas, a meaningful figure but a fraction of what would move freely without controls.4Central Banking.

The logic behind the controls is straightforward. They let Beijing keep domestic interest rates low to stimulate the economy without triggering a flood of money leaving in search of higher returns elsewhere. They also help defend against speculative attacks that could drain foreign reserves. Violations carry heavy fines and potential loss of business licenses, which keeps most participants inside the lines. The trade-off is reduced efficiency and higher transaction costs for anyone doing cross-border business in renminbi.
The Controlled Bridges Between the Two Markets
Despite the wall, Beijing has built several monitored channels linking the onshore and offshore environments. Each one lets capital flow in a specific direction under specific rules.
- Stock Connect, launched via Hong Kong, lets offshore investors buy A-shares listed in Shanghai and Shenzhen. Purchases are funded through CNH, so the money never formally enters the onshore foreign exchange market. There is no quota at the individual investor level, which makes it one of the most accessible routes into mainland equities.
- Bond Connect does the same job for fixed income, giving foreign investors access to China’s bond market. Settlement happens entirely through offshore infrastructure, with trading facilitated by platforms like Tradeweb and Bloomberg, and investors can hedge currency exposure using either onshore or offshore renminbi.
- CIPS, the Cross-Border Interbank Payment System, launched in October 2015 to handle wholesale renminbi payments between banks internationally. It connects directly to China’s domestic payment infrastructure and now includes participants from dozens of countries across six continents.6CIPS. Introduction
These channels let the renminbi function internationally without requiring China to fully open its capital account. Beijing keeps the ability to tighten or loosen access as conditions change. When outflow pressure mounts, regulators can quietly slow approvals. When they want to attract foreign capital, they expand quotas or launch new programs.
A Quick Note on Renminbi vs. Yuan
The official name of the currency is the renminbi, which translates roughly to “the people’s currency.” The yuan is the unit you count when paying for something, the way you count pounds when spending British sterling. A price tag reads 50 yuan, not 50 renminbi, though both refer to the same money. International banking codes use RMB as shorthand for the overall currency, while CNY and CNH distinguish where a particular transaction settles.
U.S. Tax and Reporting Rules for Americans Holding CNH
American investors and businesses holding offshore renminbi face two federal obligations that are easy to overlook. Gain or loss from CNH currency fluctuations is treated as ordinary income or loss under Section 988 of the Internal Revenue Code, not as capital gain. That distinction matters because ordinary rates are typically higher. There’s an exception for forward contracts, futures, and certain options held as capital assets: if you identify the transaction as a capital asset election before the close of the day you enter it, you can treat the gain or loss as capital instead.7Office of the Law Revision Counsel. 26 USC 988 – Treatment of Certain Foreign Currency Transactions
Any U.S. person with a financial interest in or signature authority over foreign financial accounts whose aggregate value exceeds $10,000 at any point during the year must also file a Report of Foreign Bank and Financial Accounts on FinCEN Form 114. An offshore CNH account at a bank in Hong Kong or Singapore counts as a foreign financial account whether or not it produced taxable income that year. Failing to file carries steep civil penalties, and willful violations can bring criminal liability.8Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR)
