The Renminbi (RMB, sign: ¥; code: CNY; also CN¥, 元 and CN元) is the official currency of the People's Republic of China (PRC). Renminbi is legal tender in mainland China, but not in Hong Kong or Macau. It is issued by the People's Bank of China, the monetary authority of the PRC. Its name (simplified Chinese: 人民币; traditional Chinese: 人民幣; pinyin: rénmínbì) means "people's currency".

The primary unit of renminbi is the yuán (元). One yuan is subdivided into 10 jiǎo (角), which in turn is subdivided into 10 fēn (分). Renminbi banknotes are available in denominations from 1 jiao to 100 yuan (¥0.1–100) and coins have denominations from 1 fen to 1 yuan (¥0.01–1). Thus, some denominations exist in coins and banknotes, but they are usually used in coins if under ¥1. Coins under ¥0.1 are used infrequently.

Through most of its history, the value of the renminbi was pegged to the U.S. dollar. As China pursued its gradual transition from central planning to a free market economy, and increased its participation in foreign trade, the renminbi was devalued to increase the competitiveness of Chinese industry. It has been claimed that the current official exchange rate is lower than the value of the renminbi by purchasing power parity, undervalued by as much as 37.5% (see below).
