USD/JPY fell about 0.4% on Tuesday and moved back below 159.00, ending near 158.85. It stayed within a two-yen range between 160.00 and 158.00, after failing near 159.30 and then bouncing from around 158.60.
The US Dollar weakened after the BLS said March PPI for final demand rose 0.5% month-on-month, below the 1.2% consensus. Core PPI increased 0.1% versus expectations of 0.6%, while petrol rose 15.7% and made up nearly half of the headline rise; services were flat.
The Dollar also softened after President Trump said peace talks with Iran could restart within two days. The Japanese Yen drew support from safe-haven demand linked to Middle East uncertainty, while BoJ policy played a smaller role.
On the 15-minute chart, USD/JPY traded at 158.83 and stayed below the day’s open at 159.21, with Stochastic RSI near 59. Resistance stood at 159.21, while the daily chart showed price at 158.84 above the 50-day EMA at 158.02 and the 200-day EMA at 154.56, with daily Stochastic RSI near 28.

We remember looking at this price action around April of last year, when USD/JPY was struggling to find direction inside a tight 158.00 to 160.00 range. That period of consolidation, marked by soft US inflation data, was a pause before the underlying trend reasserted itself. The divergence in central bank policy ultimately forced a breakout to the upside later in 2025.
Fast forward to today, April 15, 2026, the pair is trading near 168.50, demonstrating the powerful effect of the interest rate differential. The U.S. Federal Reserve’s key rate remains elevated at 5.3%, while the Bank of Japan’s rate is just 0.1%, creating a significant incentive for carry trades. This persistent gap has been the primary driver overwhelming other factors over the past year.
Unlike the surprising downside miss in the Producer Price Index we saw in March 2025, recent U.S. inflation has been stubbornly firm. The latest Consumer Price Index report for March 2026 showed a year-over-year increase of 3.5%, discouraging any thoughts of imminent rate cuts from the Fed. This backdrop suggests dollar strength will continue to be a dominant theme for the foreseeable future.
While geopolitics were a focus last year, the main risk now is direct intervention from Japanese authorities to strengthen the yen. We have heard repeated warnings from finance ministry officials about taking “decisive steps” against speculative currency moves. Historical interventions, such as those in late 2022, show that authorities can trigger sharp, multi-yen drops in the pair with no warning.
Given the high implied volatility from this intervention risk, traders should consider selling out-of-the-money puts to collect premium, betting that the strong underlying uptrend will provide support on any dips. To protect against a sudden plunge, pairing this with buying cheaper, further-dated puts creates a hedge against a sharp, intervention-driven reversal. This strategy aims to profit from the current upward momentum while respecting the significant tail risk from official action.
