What Is the Renminbi?

The Renminbi (RMB) is the official currency of the People’s Republic of China, issued by the People’s Bank of China (PBOC), the country’s central bank. Introduced in 1948 following the Communist Party’s consolidation of power, the Renminbi serves as the medium of exchange for the world’s second-largest economy. Although often used interchangeably with the term “Chinese Yuan,” the two are not strictly synonymous. “Renminbi” refers to the currency system, while “Yuan” (CNY) denotes a unit within that system. For example, prices in China are quoted in yuan, while broader discussions of monetary policy and currency are framed using the term Renminbi.

Currency Structure and Denominations

The Renminbi operates under a decimal system, where one yuan is subdivided into 10 jiao, and each jiao into 10 fen. In practice, fen are rarely used due to inflation and changes in consumer habits. Paper banknotes are issued in denominations ranging from 1 yuan to 100 yuan, and coins are available in lower denominations such as 1 jiao and 1 yuan.

The Renminbi is identified internationally using the ISO code CNY (Chinese Yuan), and RMB is used colloquially to refer to the currency. For offshore trading, particularly in Hong Kong and other global financial centers, a separate code CNH is often used to distinguish the offshore version from the onshore CNY market.

Exchange Rate Regime and Policy

Historically, China maintained a strict fixed exchange rate system, pegging the Renminbi to the U.S. dollar. This changed in July 2005, when the PBOC moved to a managed float system that allows the currency to trade within a narrow band around a reference rate set daily by the central bank. The Renminbi is not freely convertible for capital account transactions, meaning foreign investors and Chinese residents face restrictions on cross-border capital movement.

China’s central bank retains significant control over the currency's valuation, using tools such as intervention in foreign exchange markets and capital controls. This partially managed approach reflects the government's intent to maintain financial stability, support export competitiveness, and control inflation, even as the currency gradually moves toward broader international use.

Role in Domestic and Global Markets

Within China, the Renminbi is used for all forms of payment and pricing, from consumer transactions to business accounting. It is the sole legal tender in mainland China. However, its reach has extended well beyond domestic borders in recent decades.

China has actively promoted the internationalization of the Renminbi as part of a broader strategy to enhance its financial influence. Bilateral currency swap agreements, RMB-denominated trade settlement, and the creation of offshore RMB markets — especially in Hong Kong — have contributed to this goal. In 2016, the International Monetary Fund (IMF) added the Renminbi to its Special Drawing Rights (SDR) basket, recognizing it as one of the world’s major reserve currencies alongside the U.S. dollar, euro, Japanese yen, and British pound.

Nonetheless, the Renminbi’s share of global foreign exchange reserves remains relatively small. Structural barriers, such as capital controls, limited transparency, and incomplete financial liberalization, continue to constrain its full adoption as a global reserve or settlement currency.

Offshore vs. Onshore Renminbi

The Renminbi exists in two distinct markets: the onshore market (CNY) and the offshore market (CNH). The onshore market is governed by China’s domestic monetary policy and capital controls, while the offshore market — centered in Hong Kong and expanding to London, Singapore, and other global financial hubs — offers more liberalized access for international investors.

The offshore CNH is subject to fewer restrictions, allowing for more flexible trading. While the exchange rates for CNY and CNH are generally close, they can diverge due to differences in supply-demand dynamics and central bank interventions. These dual markets reflect the tension between China’s desire for international financial integration and its commitment to domestic monetary stability.

Digital Renminbi

China has also become a pioneer in central bank digital currency (CBDC) development through the Digital Currency Electronic Payment (DCEP) initiative. Commonly referred to as the Digital Renminbi or e-CNY, this state-issued digital currency aims to modernize payments, improve financial inclusion, and provide the central bank with real-time data on money flows. As of recent trials, the digital Renminbi has been tested in major cities and integrated into public transportation, e-commerce platforms, and retail stores.

The digital Renminbi operates alongside physical currency and existing mobile payment platforms like Alipay and WeChat Pay, and it offers the government enhanced control over monetary issuance, surveillance, and fraud prevention. While still in the pilot stage, its deployment is part of China's broader strategy to assert monetary sovereignty in the digital era.

The Bottom Line

The Renminbi is both a domestic tool for economic policy and an emerging instrument of global finance. It reflects China’s hybrid approach to market reform, combining central oversight with measured liberalization. While not yet fully convertible, the Renminbi’s international profile continues to expand, supported by deliberate policy initiatives and global trade relationships. Its evolving role — through traditional channels and digital innovations — will influence both regional and global financial systems in the years ahead.
