USD/JPY hovered around 160.50 for most of the session before a geopolitical jolt drove a reversal. After 17:30 GMT, President Trump said planned evening strikes on Iran had been cancelled and that a deal to end the conflict was close, pushing the pair down by one big figure to lows just above 159.50 within two hours. The move ran counter to earlier US data: May PPI rose 1.1% MoM versus forecasts near 0.7%, coming a day after a stronger CPI, while rate futures edged further towards a Fed hike rather than a cut. The market reaction suggested yields, rather than inflation prints, were setting the tone.
The shift followed a volatile 48 hours in which US forces struck Iran on Tuesday and Wednesday, and Tehran responded with ballistic missiles aimed at American bases in Bahrain, Kuwait and Jordan, before Trump earlier threatened to seize Kharg Island. Reports from Fars offered mixed signals on whether any text had been approved, while a naval blockade of Iranian ports remained. Risk repricing hit energy and rates: Brent fell more than 3% to near $90 a barrel, and the two-year Treasury yield dropped roughly 7 basis points after the cancellations. For Japan, with USD/JPY above 160.00, the pullback delivered about 100 pips of relief without Ministry of Finance action, though the move’s durability depends on confirmation of the deal and any reopening of the Strait of Hormuz this weekend in Europe.

Volatility And Intervention Risk For USD/JPY
The USD/JPY is caught in a difficult spot, trading near 157.10. The wide interest rate gap between the US and Japan argues for a stronger dollar, but the market is extremely sensitive to any news that might shift that view. Geopolitical headlines, like the recent easing of naval tensions in the Strait of Malacca, are causing sharp, sudden drops in the pair.
We see this tension playing out in the bond market. US inflation for May came in at 3.2%, slightly cooler than expected, but the Federal Reserve’s latest projections still only signal one potential rate cut this year. This policy difference should keep the dollar well-supported against the yen on paper, but traders are clearly nervous.
For Japan, any de-escalation that lowers energy prices is a major relief. With Brent crude oil dropping back toward $82 a barrel, pressure on Japan’s import costs eases slightly. This also buys the Ministry of Finance (MOF) some time, as the high exchange rate makes energy imports even more expensive for the country.
We are now back in the zone where intervention is a real threat. Japanese officials have repeatedly warned against “excessive” moves, and historical data from 2022 and 2024 shows they are not afraid to act forcefully when the yen weakens past these levels. The recent dip from above 158.00 has given them a temporary reprieve, but they are certainly watching closely.
Trading Strategies And Market Levels
The recent drop was sharp, and the bounce has been weak, stalling below 157.50. This level now appears to be acting as a new ceiling for the currency pair. Any attempt to rally back above it is meeting with selling pressure, suggesting the market is more inclined to test the downside.
Given this, we believe selling rallies toward the 157.50 level is the correct strategy for now. This market is trading on headlines, so any sign that geopolitical risks are fading or that the Bank of Japan is preparing to act will likely push the pair lower. We are trading the gap between the Fed’s slow-moving policy and Japan’s growing urgency.
A confirmed breakdown in de-escalation talks or a surprisingly hot US jobs number could be the trigger to push the pair back toward 158.00. On the other hand, a clean break below 156.50, especially if driven by official Japanese action, would open the way for a deeper slide toward the 155.00 handle.
