📌 “China operates not one, but two distinct versions of its currency for international finance.” The Onshore RMB (CNY) and Offshore RMB (CNH) look identical on paper but behave very differently in global markets. This guide explains why they exist, how they trade, and what it means for your business.
China's Renminbi (RMB) is unique because it trades in two separate markets: onshore within mainland China, and offshore outside mainland China. These are identified by different currency codes: CNY for onshore and CNH for offshore. While they represent the same currency unit, their exchange rates, trading rules, and accessibility differ significantly due to China's capital controls and internationalization strategy.
What Are Onshore RMB (CNY) and Offshore RMB (CNH)?
A Chinese manufacturing company in Shanghai receives payment in US dollars from an American buyer. It converts those dollars to RMB at a Chinese bank inside mainland China. The exchange rate used is the CNY rate set by the People's Bank of China (PBOC) with a daily trading band. This RMB can be used to pay local suppliers, employee salaries, and taxes within China, but moving it freely overseas is restricted.
A hedge fund in London wants to bet on the value of the Chinese currency. It buys CNH through the Hong Kong exchange (or other offshore centers like London or Singapore). The price is determined purely by global supply and demand, without direct intervention from the PBOC. The fund can freely trade this CNH with international counterparts, use it for bonds ("Dim Sum" bonds), or convert it to other currencies.
Key Differences: A Side-by-Side Comparison

|---|---|---|
| Trading Location | Mainland China (Shanghai, Beijing) | Outside Mainland China (Hong Kong, London, Singapore) |
| Primary Market | China Foreign Exchange Trade System (CFETS) | Hong Kong Interbank Market (CNH Market) |
| Exchange Rate Control | Managed by PBOC with a daily band (±2%) | Freely floating, set by market forces |
| Capital Controls | Strict controls on moving funds in/out | No capital controls; free convertibility |
| Typical Users | Chinese domestic companies, individuals | International investors, multinational corporations |
| Price Discovery | Reflects domestic policy goals | Reflects global risk sentiment & liquidity |
| Common Use | Settling domestic trade, salaries, taxes | International trade finance, speculation, bonds |
⚠️ Common Pitfalls & Misconceptions
- Myth: CNY and CNH are the same currency with the same value. Reality: They often trade at different prices (a spread). CNH can be weaker or stronger than CNY based on market conditions.
- Myth: You can freely arbitrage between CNY and CNH. Reality: China's capital controls prevent easy movement of funds between the two markets, limiting arbitrage opportunities.
- Myth: Offshore RMB (CNH) is not "real" RMB. Reality: CNH is fully convertible and recognized internationally, but it operates under different rules than the domestic CNY.
Why Does China Maintain Two RMB Markets?
China's dual-currency system serves a clear strategic purpose: it allows the country to gradually internationalize its currency while maintaining strict control over its domestic economy. By creating CNH, China lets global markets trade the RMB without exposing its onshore financial system to volatile foreign capital flows. This "sandbox" approach lets China test international reactions and build infrastructure for eventual full convertibility, all on its own terms.
A German machinery exporter sells goods to a buyer in China. The contract can be priced in either CNY or CNH.
If priced in CNY: The German company receives RMB in a Chinese bank account. It faces restrictions converting large amounts to euros and moving them out of China.
If priced in CNH: The payment is settled in Hong Kong. The German company receives freely convertible CNH, which it can instantly exchange for euros or other currencies with no capital controls.
An American investor believes the RMB will appreciate against the US dollar.
Investing via CNY: Extremely difficult due to China's Qualified Foreign Institutional Investor (QFII) quotas and restrictions. Access is limited and bureaucratic.
Investing via CNH: The investor can simply buy CNH/USD futures on the Hong Kong Exchange or purchase CNH-denominated bonds. The process is as easy as trading any other major currency pair.
The Future: Will CNY and CNH Ever Merge?
The gap between CNY and CNH rates has narrowed over the years as China has loosened some controls and increased market access. However, a full merger into a single, freely convertible RMB is a long-term goal, not an immediate policy. China will likely maintain the two-track system until it is confident that merging them won't lead to financial instability. For the foreseeable future, understanding both CNY and CNH remains essential for anyone involved in China-related finance or trade.
Final Takeaway: Think of CNY as the "domestic" version of China's currency, controlled for stability. Think of CNH as the "international" version, traded for opportunity. Knowing which one you are dealing with is the first step to managing China-related currency risk.
