Yen Firms as Suspected FX Intervention Hits USD/JPY

Key Moments

USD/JPY Slips as Yen Gains on Reported Official Action

The USD/JPY pair traded lower around 156.85 during the Asian session on Friday, as the Japanese Yen strengthened against the US Dollar. The move came after reports of another round of intervention by Japanese authorities in the foreign exchange market, prompting some investors to turn more cautious ahead of key US labor data.

According to a Reuters report on Friday that cited a source familiar with the matter, Japanese officials acted in the FX market during holidays in early May, following Yen-buying operations on April 30. The source said: “The intervention since the start of May was timed to coincide with the holiday period, when market liquidity was thin.”

Expectations for Further Intervention Support Yen Sentiment

The possibility that authorities could step in again is seen as a potential source of support for the Yen and a limiting factor for further gains in USD/JPY. On Thursday, Japan’s top foreign exchange official Atsushi Mimura underscored the authorities’ readiness to respond broadly to speculative moves in the currency market.

This stance has reinforced market expectations that policymakers remain vigilant about rapid or disorderly Yen weakness and are willing to act if they judge moves to be speculative in nature.

Markets Eye US April Jobs Data

Attention now centers on the US employment report for April, scheduled for release on Friday. Market consensus points to an increase of 62,000 new jobs in April, a significant slowdown from the 178,000 jobs added in March. The Unemployment Rate is projected to hold steady at 4.3%.

The outcome of the jobs report could influence expectations for US monetary policy and, in turn, affect the Dollar’s performance against the Yen, especially in a context where Japanese authorities are perceived as actively monitoring currency moves.

Key Drivers of 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.

Role of the Bank of Japan in Currency Dynamics

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.

Impact of US-Japan Yield Differentials

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.

Safe-Haven Status and Risk Sentiment

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.
