The Japanese Yen (JPY) is one of the most traded currencies in the world. Its value is largely determined by the performance of the Japanese economy, but more specifically by Bank of Japan policy, the difference between Japanese and US bond yields, or risk sentiment among traders, among other factors.

One of the Bank of Japan’s mandates is currency control, so its moves are key for the yen. The BoJ has intervened directly in currency markets on occasion, generally to depress the yen, although it refrains from doing so because of the political concerns of its main trading partners. The BoJ’s current ultra-loose monetary policy, based on massive stimulus to the economy, has caused the yen to depreciate against its major peers. This process has been exacerbated more recently by a widening policy divergence between the Bank of Japan and other major central banks, which have opted to raise interest rates sharply to combat decades-high levels of inflation.

The BoJ’s stance of sticking to ultra-loose monetary policy has led to increased policy divergence with other central banks, particularly the US Federal Reserve. This supports a widening of the spread between US and Japanese 10-year bonds, which favors the US dollar against the Japanese yen.

The Japanese yen is often seen as a safe investment. This means that during periods of market stress, investors are more likely to put their money into the Japanese currency due to its supposed reliability and stability. Troubled times are likely to strengthen the value of the yen against other currencies considered riskier to invest in.
