USD/JPY drifted towards 159.00 on Monday and closed near 158.80, its sixth straight daily fall for the yen. The session range was about 60 pips, and around half of the roughly 400-pip rise seen after intervention measures that began on 30 April has been reversed.
Japan’s rates remain near zero while markets discuss another possible US rate rise linked to energy-led inflation. Tensions involving Iran and disruption in the Strait of Hormuz have kept oil prices firm, adding to US inflation pressure and raising Japan’s energy import costs.
Policy Outlook And Rate Differential
BoJ board member Kazuyuki Masu said rates should rise as soon as possible due to inflation risks. The OECD forecasts the BoJ policy rate will reach 2% by end-2027.
Japan’s preliminary Q1 GDP is due at 23:50 GMT, with forecasts of 0.4% QoQ (from 0.3%), 1.7% annualised (from 1.3%), and a 3.1% deflator (from 3.4%). FOMC Minutes follow on Wednesday at 18:00 GMT, while Thursday’s Japan CPI is seen near 1.5% YoY headline and 1.8% core.
Support is cited at 158.50 and 158.00, with resistance at 159.00, then 159.50 and 160. On a 15-minute view, price was 158.79 after a 159.08 high, with Stochastic RSI near 18; on the daily chart, price near 158.83 sits above the 50-day EMA at 158.14 and 200-day EMA at 155.40. Tokyo has said intervention can be repeated without limit, and US Treasury Secretary Scott Bessent has voiced support.
Looking back to this time in 2025, we were watching the USD/JPY grind towards 159, driven by the wide gap between central bank policies. That core theme has only intensified over the last year, as the Federal Reserve has held rates at 5.50% while the Bank of Japan has only managed a token hike to 0.25%. With the pair now trading around 162.50, the interest rate differential continues to be the primary force pushing the yen lower.
Volatility And Intervention Risk
The key change since last year is that the threat of intervention is no longer theoretical, making volatility the main product to trade. After officials spent over $60 billion on interventions in the spring of 2024, the market understands that sudden 400-pip drops are a real possibility whenever the pair approaches new highs. This risk keeps one-month implied volatility elevated, currently sitting near 9.5%, meaning options are pricing in the potential for sharp, unexpected moves.
Given this environment, buying long-dated call options on USD/JPY offers a way to stay with the uptrend while strictly defining your maximum loss. This strategy avoids the negative carry of being long spot yen and protects you from a sudden plunge caused by intervention. The cost of these options is high due to volatility, but it buys you protection against the biggest risk on the board.
For those who believe the Ministry of Finance will successfully pin the exchange rate in a range, selling volatility could be attractive. An iron condor, selling a call spread above 165.00 and a put spread below 159.00, allows you to collect premium as long as the pair remains contained. This is a bet that official intervention threats and the underlying interest rate support will create a tense but stable equilibrium for a few weeks.
Upcoming data, particularly this Friday’s U.S. Personal Consumption Expenditures (PCE) inflation report, will be the next major catalyst. A higher-than-expected inflation reading would reinforce the Fed’s patient stance, adding more upward pressure on USD/JPY and testing the resolve of Japanese officials. Conversely, a soft number could provide the yen with some temporary relief and take pressure off the 163.00 level.
The technical picture shows that while the trend is clearly up, the risk is skewed towards sharp, sudden reversals. The 160.00 level, which was the line in the sand last year, now serves as major psychological support. Using these key levels to structure options trades is more prudent than trying to chase momentum in the spot market, where intervention risk can erase weeks of gains in minutes.
