Japanese Yen (JPY): Currency Overview, Historical Significance, and Practical Insights


Discover the world of JPY (Japanese yen) – Japan’s currency. Learn about its significance in global markets, recent developments, and key takeaways that every investor should know.

What is Japanese yen?

The Japanese yen, often symbolized as ¥, is a prominent player in the world of international finance. This article provides a comprehensive overview of the Japanese yen (JPY) – its importance in global currency markets, historical context, and its role as a safe haven. We’ll delve into the key takeaways, recent developments, and the denominations of this currency.

Understanding JPY (Japanese yen)

The Japanese yen, abbreviated as JPY, is the official currency of Japan. It is the third-most traded currency in the foreign exchange market, following the U.S. dollar (USD) and the euro. In a 2019 survey, the yen was involved in trades representing 16.8% of the foreign currency trading turnover. This percentage, although significantly lower than the dollar and euro, signifies the yen’s importance on the global stage.

JPY as a safe haven

The yen has often been considered a safe haven during times of market stress. However, in mid-2022, it experienced a significant drop, reaching 24-year lows against the U.S. dollar. This drop was attributed to the Bank of Japan’s (BoJ) refusal to follow other central banks in raising interest rates.

BoJ’s inflation target

The Bank of Japan has set a 2% inflation target for the country, marking a shift from decades of economically damaging deflation. This target aims to stimulate economic growth and reduce the risk of deflation, making the yen’s future trajectory a critical factor to monitor for investors.

Recent developments

The recent performance of the Japanese yen is a key area of interest for investors and financial analysts. In mid-2022, the yen reached 24-year lows against the U.S. dollar, which raised concerns in the global financial community. This decline was primarily driven by the Bank of Japan’s decision to maintain low-interest rates, deviating from the trend of central banks in other developed nations.

JPY denominations

Understanding the denominations of the Japanese yen is essential for both residents and travelers. Japan uses a unique system, where coins worth 1, 5, 10, 50, 100, and 500 yen are in circulation. Banknotes come in denominations of ¥1,000, ¥2,000, ¥5,000, and ¥10,000. Notably, Japanese counting systems often use multiples of 10,000 yen instead of 1,000, as commonly done in the Western world with U.S. dollars or euros.

Foreign reserves and current account surplus

The Japanese yen holds a distant third place in terms of foreign exchange reserves, following the U.S. dollar and the euro. As of Q4 2021, reserves held in dollars exceeded those held in yen by more than 10-fold. This is partly due to Japan’s current account surplus, stemming from its role as a major net exporter, which limits the accumulation of yen by foreign central banks.
