yen

yen. The official currency of Japan, it is the third-most traded currency in the world after the United States dollar and the euro. Issued by the Bank of Japan, the yen is a key reserve currency and a frequent subject of intervention in foreign exchange markets. Its symbol is ¥, and its ISO 4217 code is JPY.

History

The yen was introduced in 1871 by the Meiji government as part of the New Currency Act, replacing the complex mon system of the Edo period with a decimal-based system. This modernization was influenced by Western monetary systems, particularly the Spanish dollar, and aimed to stabilize the nation's finances. Following World War II, the yen's value was fixed at 360 to the United States dollar under the Bretton Woods system, a rate maintained until the system's collapse in the early 1970s. The Plaza Accord of 1985, an agreement among the Group of Five nations, led to a dramatic appreciation of the yen, significantly impacting Japanese export industries and contributing to the asset price bubble in Japan. Subsequent decades have seen prolonged periods of deflation and aggressive monetary policies from the Bank of Japan, including quantitative easing programs.

Coins and banknotes

Coins are minted by the Japan Mint and come in denominations of ¥1, ¥5, ¥10, ¥50, ¥100, and ¥500, with the latter featuring a distinctive bi-metallic design. Banknotes, issued by the Bank of Japan, feature prominent cultural and historical figures; the ¥1000 note depicts Hideyo Noguchi, the ¥5000 note features Ichiyō Higuchi, and the ¥10,000 note portrays Eiichi Shibusawa. A commemorative ¥2000 note was issued in 2000 to mark the 26th G8 summit in Okinawa. Security features are highly advanced, incorporating holograms, intaglio printing, and luminescent ink to prevent counterfeiting. New series of banknotes, featuring updated designs and enhanced security, are scheduled for release in 2024.

Exchange rates and value

The exchange rate is a floating currency, determined by trading in the global foreign exchange market, making it highly sensitive to economic indicators and geopolitical risk. Historically, it experienced significant strength following the Plaza Accord, reaching post-war highs against the United States dollar in the 1990s. In recent years, the Bank of Japan's persistent ultra-loose monetary policy, in contrast to tightening by the Federal Reserve and the European Central Bank, has often led to a weaker valuation. This dynamic makes it a popular funding currency for carry trade strategies, where investors borrow in low-yielding currencies to invest in higher-yielding assets elsewhere.

Role in the global economy

As a major reserve currency, it is held in significant quantities by central banks worldwide, including the Federal Reserve and the People's Bank of China. It is the dominant currency for transactions within Asia and is heavily used in the settlement of international trade, particularly for commodities. The currency is also a benchmark in international finance, with the LIBOR including a yen-denominated rate. Japan's status as one of the world's largest creditor nations and the deep liquidity of its Japanese government bond market further cement its global financial importance. Movements in its value are closely watched by institutions like the International Monetary Fund and major investment banks such as Goldman Sachs.

Currency code and symbols

The international three-letter code, as standardized by ISO 4217, is JPY, used in banking and foreign exchange transactions globally. The symbol "¥" is derived from the first letter of the country's name in the Latin alphabet, mirroring the style of other currency symbols like the dollar sign ($). In Japan, the character "円" is used, which is the same kanji used for the word "round," reflecting the coins' shape. In computer systems and financial software, the currency is consistently identified by its ISO code to avoid confusion with other currencies, such as the Chinese yuan, which also uses the ¥ symbol.
