Japanese Yen leaks lower as the BoJ keeps pretending nothing is wrong
- USD/JPY pushed up through the 159.00 area on Tuesday, posting an intraday high just above that level before settling on the figure into the close, with the Japanese Yen leaking lower against a firm US Dollar.
- Japan's national Consumer Price Index (CPI) is due Thursday, with headline inflation seen at 1.5% year-on-year and core measures still printing softer than the prior month.
- Federal Open Market Committee (FOMC) Minutes Wednesday and US flash Purchasing Managers Index (PMI) data Thursday provide the Dollar-side test that decides whether 160 gets retaken this week.
The Yen's slow drift back toward 160.00 has the feel of a market that has stopped waiting. USD/JPY climbed through Tuesday's London and New York sessions, posting a session peak just above 159.00 before settling near that figure into the close, with the move running on US Dollar strength rather than anything new on the Yen side. The Bank of Japan (BoJ) remains the silent presence in the room, with policy frozen and the official line still that price pressures are easing back to target on their own.
The data due Thursday does little to argue against the BoJ holding. Japan's national CPI is forecast at 1.5% year-on-year (YoY) for April, with the ex-Fresh Food gauge at 1.7% versus 1.8% prior and the ex-Food and Energy measure softening to 2.4%. The direction of travel is genuinely down, and even a modest beat on the ex-Fresh Food print would not be enough on its own to force the BoJ's hand. The market knows this, which is why USD/JPY trades like a pair where the rate differential is the only story that still moves it.
Why 160.00 keeps catching the eye
The 160.00 handle has been the line in the sand for Tokyo since the intervention episodes earlier in the cycle. USD/JPY printed a year-to-date high just above 160.00 earlier in May before being slapped back toward 156.00, and the recovery off that low has been almost a straight line. With price now back near 159.00 and momentum still running, the question is whether traders test the Ministry of Finance's patience a second time inside a single quarter. The Stochastic RSI on the daily chart is reading lower than it has been at any recent peak, which leaves room for the move to extend before it gets stretched.
The Fed side of the trade
The bigger swing factor this week is on the Dollar leg. FOMC Minutes land Wednesday at 18:00 GMT, and the market will read them for any sign that the recent run of speeches from regional Fed presidents reflects a broader committee shift rather than the usual policy-spread theatre. Thursday's US flash PMIs, with Manufacturing seen at 54 and Services holding around 51, are both marked high-impact. A firm set on either side keeps the Dollar bid and effectively forces the Yen lower regardless of what the Tokyo CPI does that same evening.
Setup into the end of the week
A daily close above 160.00 is the technical trigger that matters, and at current levels it is well within a session's range. The pattern of higher lows since the early May washout is intact, and the 50-day EMA on the daily sits just below price as the support line for any pullback. The path of least resistance is up unless the Fed Minutes deliver a meaningfully dovish surprise.
Friday's Fed Chair swearing-in is the wildcard. The new Fed leadership starts the week with an open inflation question, no signal yet on how the dot plot shifts, and a Dollar that wants to keep going. The Yen, as usual, gets caught in the middle.
USD/JPY 5-minute chart
Technical Analysis
In the five-minute chart, USD/JPY trades at 159.06. The pair holds a bullish intraday bias as price trades above the day’s opening level at 158.77, indicating buyers remain in control on dips. Momentum is stretched on the Stochastic RSI, which sits in overbought territory near 76.8, hinting that upside progress could slow even as the short-term tone stays constructive while above the intraday pivot around the current price zone.
On the downside, immediate support is seen at the day’s open near 158.77, where a break would signal fading intraday demand and expose deeper pullbacks. As long as USD/JPY remains above that floor, the path of least resistance stays higher in the near term, though overbought momentum readings warn that new highs may attract profit-taking rather than fuel an aggressive continuation.
In the daily chart, USD/JPY trades at 159.06. The pair holds a constructive bullish bias as spot remains above both the 50-day Exponential Moving Average (EMA) at 158.17 and the 200-day EMA at 155.29, suggesting the broader uptrend stays intact despite recent volatility. The Stochastic RSI around 54 leans slightly positive, hinting that upside momentum is stabilizing rather than overextended at current levels.
On the downside, immediate support is seen near the 50-day EMA at 158.17, with a deeper cushion at the 200-day EMA around 155.29 if selling pressure accelerates. As long as buyers defend these moving average supports, the technical structure favors further consolidation with a modest topside bias, even though clearly defined resistance levels are not yet visible in the immediate vicinity of the current price.

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.
