China’s currency is unusual. It is officially managed by the central bank, trades in two different markets, and has two different codes. For traders, the one to watch is usually USD/CNH, the US dollar against the offshore yuan. It is one of the clearest signals of how the world feels about China, trade and global risk. Here is how it works.
Renminbi, yuan, CNY and CNH
China’s currency is officially called the renminbi, which means the people’s currency. The yuan is its unit, a bit like the difference between sterling and the pound. In practice, the terms are used interchangeably.
The currency trades in two places. Onshore, within mainland China, it is called CNY and is tightly controlled. Offshore, mainly in Hong Kong but also in London, Singapore and elsewhere, it is called CNH and trades more freely. They are the same currency, but because money cannot move between the two markets without restriction, their prices can differ.
How the onshore rate is managed
Each morning, the People’s Bank of China sets a central reference rate for the onshore yuan against the dollar, known as the daily fixing. The onshore rate is then allowed to trade within a band of 2 per cent either side. The fixing is a powerful policy tool. A stronger-than-expected fixing signals that Beijing wants to support the currency; a weaker one suggests it is willing to let it slide. Our guide to the daily yuan fixing explains it in more detail.
Why CNH matters to traders
Because the offshore market is freer, USD/CNH tends to react faster to news and sentiment. International investors use it to express views on China and to hedge exposure. When the gap between CNH and CNY widens, it can signal pressure building on the currency, or the authorities stepping in.
The offshore yuan is also used as a gauge of wider risk appetite in Asia. A rising USD/CNH, meaning a weaker yuan, often coincides with worries about Chinese growth, trade tensions or capital leaving the country. Those moves can ripple into other Asian currencies, commodities and currencies tied to China, such as the Australian dollar.
What moves USD/CNH
Trade policy. Tariffs and trade negotiations between the US and China have been major drivers. A weaker yuan can make Chinese exports cheaper, which makes the currency politically sensitive.
Interest rate gaps. When US interest rates are well above Chinese rates, holding dollars is more attractive, which tends to push USD/CNH higher.
Chinese data and stimulus. Growth figures, property market news and stimulus announcements all affect confidence in the currency.
Intervention. Chinese authorities can influence the offshore market, for example by tightening the supply of yuan in Hong Kong, making it more expensive to bet against the currency.
Risks for traders
USD/CNH can sit in a narrow range for long periods and then move sharply when policy changes. Intervention can reverse moves quickly and without warning. Trading hours, liquidity and broker spreads vary, and news from Beijing often arrives during the Asian session. Treating it like a free-floating major currency can be a costly mistake.
The bottom line
USD/CNH is the dollar against the offshore yuan, a freer cousin of the tightly managed onshore rate. It reflects trade politics, interest rate gaps and confidence in China, and it often acts as an early warning for wider markets.
