Renminbi (RMB) is the official name of China’s currency, and the yuan (CNY) is its basic unit. Renminbi means “people’s currency” in Mandarin. You hold renminbi, but you count it in yuan. A price of 50 yuan is a price in renminbi, expressed in units of yuan. China does not have two currencies. It has one currency with a name and a unit, plus several codes and labels that appear in trading and everyday speech.

Yuan vs. Renminbi: Key Differences

The two terms work at different levels. Renminbi names the currency system as a whole, the money issued by the PBOC. Yuan is the unit of account, the thing you count. British money offers a close parallel: sterling is the currency, and the pound is its unit. You would say the UK uses sterling, and that a coffee costs three pounds. In China, the currency is renminbi, and the coffee costs 30 yuan.

In practice the words are used interchangeably, and that is rarely a problem. “RMB 500” and “500 yuan” describe the same amount. The distinction matters mostly in formal and financial contexts:

A forex broker quoting China’s currency will use USD/CNY or USD/CNH. You will not see “USD/RMB” as a standard pair code, even though many traders say RMB out loud.

How the Renminbi Works

Units and denominations

One yuan divides into 10 jiao, and one jiao divides into 10 fen, so one yuan equals 100 fen. In spoken Chinese the jiao is often called mao, and the yuan is often called kuai, so a price of 12.50 yuan might be said as “12 kuai 5 mao.”

Banknotes are issued in 100, 50, 20, 10, 5 and 1 yuan denominations, with 100 yuan the largest. Smaller amounts circulate as coins, though mobile payment apps now handle a large share of everyday spending in mainland China.

Symbol and code

The yuan is written with the character 元 and often shown with the symbol ¥, the same symbol the Japanese yen uses. To avoid confusion, financial documents use the code CNY, and some writers use “CN¥” or “RMB ¥.” The ISO 4217 standard assigns CNY to the mainland currency; there is no separate ISO code for RMB.

How the exchange rate is managed

The renminbi is not a free-floating currency. Each trading day the PBOC sets a central parity rate, or midpoint fixing, against the U.S. dollar, based on previous trading and moves in international currency markets. The onshore yuan is then allowed to trade within 2% on either side of that fixing. The central bank has at times also adjusted the midpoint with a “countercyclical factor” whose inputs it does not fully define.

Hypothetical example of the band: if the PBOC fixed USD/CNY at 7.10, the onshore rate could trade from 7.10 × 0.98 = 6.958 to 7.10 × 1.02 = 7.242 that day. The fixing moves daily, so the band moves with it.

The offshore market in Hong Kong and other financial centers is less restricted, which is why CNH can drift away from CNY. Capital controls limit how freely money moves between the two pools, so the gap does not always close quickly. That price difference is the kind of gap arbitrage traders watch, although access to the onshore market is restricted for most foreign participants.

A Short History of the Yuan and the Renminbi

The word yuan means “round” in Mandarin. It was applied to the round silver Spanish dollars that European merchants brought to China in the 17th and 18th centuries. China began minting its own silver yuan coins in 1889, and both the late Qing dynasty and the early Republican government circulated silver yuan coins and notes.

The renminbi came later. The PBOC issued the first renminbi notes in December 1948, during the Chinese Civil War and roughly a year before the Communist Party took power. The new currency replaced a patchwork of regional currencies and broke with the previous government’s money, which had suffered severe hyperinflation. In 1955 the currency was redenominated at 10,000 old yuan to one new yuan.

During the command-economy era the exchange rate was fixed by the state. The yuan was pegged at 2.46 to the U.S. dollar until 1971. As China opened to world trade, the PBOC let the yuan trade internationally, but under the managed system described above rather than a free float.

The currency’s international role has grown since then. The IMF added the yuan to the Special Drawing Rights (SDR) basket in 2016, alongside the dollar, euro, yen and pound, and raised its weight in the basket in 2022.

Why It Matters

For traders and businesses, the main consequence of the renminbi’s structure is that its price is partly a policy decision. A managed rate can stay stable for long stretches and then move sharply when the fixing is adjusted.

The managed rate has also been a long-running political issue. Critics argue that China has kept the yuan undervalued against the dollar, which would make Chinese exports cheaper abroad. The U.S. Treasury formally labeled China a currency manipulator in 2019 and removed the designation the following year. The IMF, by contrast, said in 2018 that the yuan was broadly in line with economic fundamentals.

For importers and exporters invoicing in yuan, these swings affect margins directly, which is why many use forward contracts or other hedging tools.

Example: Reading a Yuan Quote

The quote USD/CNY = 7.00 (a hypothetical rate, not a current one) means one U.S. dollar buys 7.00 yuan.

• Converting dollars to yuan: 1,000 USD × 7.00 = 7,000 yuan.
• Converting yuan to dollars: 1 ÷ 7.00 = about 0.143 USD per yuan, or roughly 14 cents.

The direction of the quote matters. Because USD/CNY shows yuan per dollar, a rising number means a weaker yuan. If the rate moved from 7.00 to 7.20, each dollar would buy 0.20 more yuan, and each yuan would be worth less in dollars (1 ÷ 7.20 is about 0.139 USD).

Now suppose, again hypothetically, that onshore USD/CNY is 7.00 while offshore USD/CNH is 7.03. The offshore yuan is weaker by 0.03 yuan per dollar, a gap of about 0.43% (0.03 ÷ 7.00). A company converting money in Hong Kong would get slightly more yuan per dollar than one converting onshore at that moment.

Limitations and Common Confusions

“Yuan” is not unique to mainland China. The same character is used in the names of the Hong Kong dollar and the New Taiwan dollar, and Mandarin uses yuan when translating foreign currencies: the U.S. dollar is mei yuan. Context or the ISO code tells you which currency is meant.

Yuan, yen and won are related words, not the same money. The Japanese yen and Korean won trace back to the same Chinese character for “round,” but they are separate currencies. China does not use the yen. The shared ¥ symbol adds to the confusion, which is why CNY and JPY codes are used in finance.

The digital yuan is not a separate currency. The e-CNY is a digital form of the renminbi issued by the PBOC, denominated in yuan. Access has been rolled out through Chinese banks and payment services such as WeChat and Alipay in selected cities, and it is aimed mainly at users inside mainland China rather than international buyers.

The Bottom Line

The renminbi matters most to forex traders and to importers and exporters who invoice in yuan. Its price is partly a policy decision, so a stable rate can shift sharply when the daily fixing changes, and offshore CNH can drift from onshore CNY. Using the correct code and reading quote direction carefully avoids costly mistakes, and many businesses use forward contracts or other hedging tools to protect margins.
