USD/JPY has been trading without a clear trend above 159.00 after Japan’s Ministry of Finance carried out record FX intervention to restrain the pair near 160.00. Over the period from 28 April to 27 May, the ministry bought ¥11.735 trillion, the largest total on record, reinforcing an official ceiling around the 160.00 area.
A pullback in crude oil prices is easing pressure on the yen and could steer USD/JPY towards 155.00. However, a sustained move materially below that level would likely require a more hawkish Bank of Japan stance, while underlying CPI measures softened in April.
Range-Bound Trading After Historic Ministry of Finance Intervention
We see the USD/JPY pair as being firmly range-bound for the next several weeks. The Japanese government’s record ¥11.7 trillion intervention has established a very strong ceiling around the 160.00 level. This heavy-handed action signals that any moves above this point will be met with significant selling pressure from authorities.
Given this hard cap, we believe selling out-of-the-money call options or establishing bear call spreads with strikes at or above 160.00 is the most logical trade. Implied volatility for one-month options has already fallen from over 12% in late April 2026 to just under 8.5% today, reflecting the market’s belief that upside is limited. This environment makes selling premium an attractive strategy.
Strategy: Trading the Range Amid Cautious Bank of Japan and Weaker Commodity Prices
The potential for a move down toward 155.00 is supported by softening commodity prices. WTI crude oil has recently fallen below $85 per barrel for the first time in three months, easing some inflationary pressure on Japan’s economy. This could give the yen a modest boost, but it’s not enough for a major trend reversal.
A significant break below 155.00 would require a more aggressive Bank of Japan, which we do not expect in the near term. Japan’s latest “core-core” inflation data for April 2026 came in at 1.8%, still below the central bank’s 2% target and showing a slight cooling trend. This gives the BoJ cover to maintain its cautious stance through its upcoming June meeting.
Therefore, our primary strategy is to trade the range by selling volatility, as seen in similar post-intervention periods in 2022 and 2024. We will be buying puts with a 155.00 strike as a cheaper way to position for a drift lower, while simultaneously selling calls near the 160.00 ceiling. This structure is designed to profit from the expected sideways price action.
