What Is the Chinese Yuan?

The Chinese Yuan (CNY) is the official currency of the People's Republic of China and is issued by the People's Bank of China (PBOC), the country’s central bank. The currency unit is known as the Renminbi (RMB), meaning “people’s currency,” while yuan refers to the unit of account. In financial markets, CNY refers to the onshore yuan traded within mainland China under the oversight of the PBOC, distinguishing it from the CNH, which denotes the offshore yuan traded outside mainland borders.

The yuan is a key component of the global monetary system due to China’s economic size, export strength, and growing international influence. While it has traditionally been tightly controlled by the Chinese government, recent decades have seen gradual efforts to increase its international usage and financial market accessibility.

Historical Background

The yuan has undergone significant transformations since its modern establishment. The first modern yuan was introduced in 1948 by the PBOC as part of a monetary unification process under the new Communist government. Prior to this, China experienced a fragmented monetary system with various regional currencies and rampant hyperinflation.

During the mid-20th century, the yuan operated under a fixed exchange rate regime and was not convertible for international transactions. Reforms began in the late 1970s with the opening of China’s economy, but exchange rate liberalization occurred more noticeably in the 1990s and 2000s. The dual exchange rate system was abolished in 1994, leading to a unified, managed floating exchange rate regime.

In 2015, the International Monetary Fund (IMF) included the yuan in its Special Drawing Rights (SDR) currency basket, recognizing its growing role in international finance. This marked a significant milestone in the currency’s path toward internationalization.

Onshore vs Offshore Yuan

The yuan operates in two distinct markets: CNY and CNH. CNY is used in mainland China and is subject to direct regulation by the PBOC. Its daily midpoint, known as the reference rate, is set each morning and can only trade within a band around that midpoint. This allows the central bank to maintain a level of stability in exchange rate fluctuations while accommodating limited market forces.

CNH is traded primarily in offshore markets such as Hong Kong, Singapore, and London. The offshore market is generally more liberalized and subject to fewer direct interventions. While CNY and CNH are essentially the same currency, the divergence in regulatory frameworks means their exchange rates can vary slightly due to differences in market conditions and liquidity.

Exchange Rate Regime and Convertibility

The Chinese yuan operates under a managed float system. The PBOC sets a central parity rate each day against a basket of currencies and allows the yuan to fluctuate within a pre-set band (as of 2025, the band is generally ±2% against the U.S. dollar). Though the currency is not freely floating, market forces have a growing influence on its value, particularly through the offshore CNH market.

In terms of convertibility, the yuan remains partially convertible. It is fully convertible on the current account, which covers trade in goods and services, but still faces capital controls under the capital account. This means that cross-border flows related to investments and financial instruments are regulated and often subject to quotas or approval processes.

International Role and SDR Inclusion

The yuan’s inclusion in the IMF’s SDR basket in 2016 marked a pivotal moment in its global standing. It joined the U.S. dollar, euro, Japanese yen, and British pound as one of the five major international reserve currencies recognized by the IMF. This inclusion signaled that the yuan met key criteria related to export importance and being "freely usable" in global transactions.

In recent years, China has signed multiple bilateral currency swap agreements with central banks around the world and promoted yuan-denominated trade settlements, especially through its Belt and Road Initiative. Central banks and sovereign wealth funds have gradually increased their holdings of yuan-denominated assets, including Chinese government bonds.

Central Bank Digital Currency (e-CNY)

The PBOC has also been a global leader in developing a central bank digital currency (CBDC). The digital version of the yuan, officially called the e-CNY, has been tested in multiple Chinese cities and is expected to coexist with physical cash. The goal of the e-CNY is to enhance payment efficiency, improve financial inclusion, and support monetary policy implementation while retaining control over the financial system.

Monetary Policy and Issuance

The yuan is issued by the People’s Bank of China, which controls money supply and interest rates through various instruments, including reserve requirements, open market operations, and the loan prime rate (LPR) system. The PBOC also uses foreign exchange reserves and administrative tools to influence the currency’s value and manage external shocks.

Monetary policy in China is characterized by a dual mandate: promoting economic growth and maintaining currency stability. Given China’s complex economic structure and evolving financial markets, the central bank often exercises a more hands-on role in monetary and credit conditions than typical Western central banks.

The Bottom Line

The Chinese Yuan (CNY) is the official currency used in mainland China and plays a growing role in international finance. While still subject to government control, the yuan has gradually liberalized and gained recognition on the global stage, particularly through its SDR inclusion and expanding cross-border usage. With ongoing reforms, increased market participation, and the rollout of its digital currency, the yuan is positioned to play a more significant role in global financial systems in the decades ahead.
