USD/JPY extends its losses for the second successive day, trading around 159.90 during the Asian hours on Friday. The currency pair depreciated as the Japanese Yen (JPY) found support from heightened fears of government intervention.

Japan’s Finance Minister Satsuki Katayama renewed warnings to the market as the JPY hovered near the critical 160.00 per USD level, emphasizing that authorities remain fully prepared to take appropriate action in the foreign exchange market as needed.

Speculation is mounting that Tokyo has already stepped into the market, backed by a sharp decline in financial buffers. Japan’s foreign reserves plummeted by USD 77.11 billion to end May at USD 1.31 trillion, down from USD 1.38 trillion in the previous month and marking their lowest level since July last year. Within these reserves, foreign currency holdings fell to USD 1.09 trillion, consisting of USD 931.68 billion in securities and USD 162.24 billion in deposits.

Meanwhile, Prime Minister Sanae Takaichi noted that while a weak Yen carries both advantages and disadvantages, Tokyo’s economic policies are designed to boost domestic economic capacity rather than manipulate the currency.

On the macroeconomic front, Overall Household Spending in Japan dropped 0.5% year-on-year in April 2026. While this marked the fifth straight month of contraction, it represented an easing from the 2.9% decline seen in the prior month and beat market expectations for a deeper 1.5% fall.

Conversely, Labor Cash Earnings grew by 3.5% year-on-year in April, accelerating from an upwardly revised 3.1% rise in the previous month and surpassing market forecasts of 3.2%. This marked the 52nd consecutive month of growth in nominal wages, significantly strengthening the case for a BoJ interest rate hike at its upcoming June 15–16 meeting.

Japanese Yen FAQs

What key factors drive the Japanese Yen?

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

How do the decisions of the Bank of Japan impact the Japanese Yen?

One of the Bank of Japan’s mandates is currency control, so its moves are key for the Yen. The BoJ has directly intervened in currency markets sometimes, generally to lower the value of the Yen, although it refrains from doing it often due to political concerns of its main trading partners. The BoJ ultra-loose monetary policy between 2013 and 2024 caused the Yen to depreciate against its main currency peers due to an increasing policy divergence between the Bank of Japan and other main central banks. More recently, the gradually unwinding of this ultra-loose policy has given some support to the Yen.

How does the differential between Japanese and US bond yields impact the Japanese Yen?

Over the last decade, the BoJ’s stance of sticking to ultra-loose monetary policy has led to a widening policy divergence with other central banks, particularly with the US Federal Reserve. This supported a widening of the differential between the 10-year US and Japanese bonds, which favored the US Dollar against the Japanese Yen. The BoJ decision in 2024 to gradually abandon the ultra-loose policy, coupled with interest-rate cuts in other major central banks, is narrowing this differential.

How does broader risk sentiment impact the Japanese Yen?

The Japanese Yen is often seen as a safe-haven investment. This means that in times of market stress, investors are more likely to put their money in the Japanese currency due to its supposed reliability and stability. Turbulent times are likely to strengthen the Yen’s value against other currencies seen as more risky to invest in.
