USD/JPY churns near 157.00 after the BoJ's FX intervention shock
- The BoJ executed roughly $30 billion in Yen-buying intervention on April 30 and May 1, defending the 160.00 ceiling.
- Last week's BoJ rate hold at 0.75% drew three dissenting votes for a hike, lifting the chances of a June increase.
- Friday's US NFP could spark fresh Yen volatility, with the print expected to slow sharply to 60K from 178K prior.
USD/JPY traded essentially flat on Monday, settling close to 157.20 after a choppy session that opened with an early-Asia gap lower toward 156.20 before staging a steady recovery through European and US trade. The pair has been hemmed into a narrow 157.50-157.00 band following last week's two-day collapse from above 160.00, with overlapping wicks and small-bodied candles pointing to indecision and two-sided whipsaws through Monday's session.
On the Yen side, an estimated $30 billion of Yen-buying intervention by the BoJ on April 30 and May 1 defended the 160.00 level after USD/JPY's sustained climb, fueled by elevated crude oil prices and Japan's deteriorating terms of trade. Last week's policy meeting also saw the central bank hold rates at 0.75%, but three of the nine board members dissented in favour of a hike. The split marked the largest opposition to a policy decision under Governor Ueda, lifting market-implied odds of a June increase.
For the US Dollar, Friday's Non-Farm Payrolls (NFP) print is the dominant near-term catalyst, with consensus penciling in 60K jobs added against the prior 178K reading and the unemployment rate seen holding at 4.3%. Tuesday's Institute for Supply Management (ISM) Services PMI and JOLTS Job Openings, alongside Wednesday's ADP private payrolls release, will set the tone earlier in the week. A soft NFP figure could rekindle US Dollar weakness and add momentum to the Yen's recovery, complicating the path forward for Japanese authorities should the pair drift lower.
USD/JPY 15-minute chart
Technical Analysis
In the fifteen-minute chart, USD/JPY trades at 157.19. The pair holds a mild bullish intraday bias as it trades above the daily open at 156.91, suggesting dip-buying interest on shallow pullbacks. The Stochastic RSI has advanced into higher territory with a latest reading near 81, hinting at overbought conditions that could slow upside momentum even as price action remains supported above the opening level.
On the downside, immediate support is located at the daily open around 156.91, where buyers may look to defend the short-term uptrend. A sustained break below this level would signal fading bullish pressure on the fifteen-minute timeframe and expose deeper retracements toward prior session lows, while holding above it keeps the door open for further intraday gains despite stretched momentum signals.
In the daily chart, USD/JPY trades at 157.23. The pair sits between the 50-day Exponential Moving Average (EMA) at 158.34 acting as immediate overhead resistance and the 200-day EMA at 154.99 providing underlying support, leaving the broader bias neutral while the market consolidates within this band. The Stochastic RSI around 54 suggests balanced momentum after the recent pullback, hinting that neither bulls nor bears currently have a decisive edge.
On the topside, a daily close above the 50-day EMA at 158.34 would be needed to reopen the path toward the prior highs and signal that buyers are regaining control. On the downside, the 200-day EMA at 154.99 is the key structural floor; a break beneath this longer-term average would weaken the medium-term outlook and expose deeper losses toward previous swing lows.

Japanese Yen FAQs
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.
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.
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.
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.
