USD/JPY pushed up to about 157.55 in early Asian trade on Tuesday as the yen weakened after the Bank of Japan failed to deliver overtly hawkish guidance following last week’s increase. The BoJ lifted rates by 25 bps to 1.25%, the highest level in 31 years, on a 7–2 vote. Swaps markets price less than 20% odds of another move at the end-October meeting, but a 90% chance of an increase in December. Separately, officials were reported to have carried out rate checks, a step markets often treat as a precursor to currency intervention, as the pair edges towards 160.00.
Attention also turns to Federal Reserve rhetoric, with speeches due from John Williams, Philip Jefferson and Thomas Barkin. St Louis Fed President Alberto Musalem said further tightening may be needed to curb inflation fuelled by strong demand and a commodity price shock beyond oil. Markets now imply a 56.5% probability of at least a 25 bps hike in October, up from 43.5% a week earlier. Technical levels place resistance at the 100-day MA of 159.55 and near 161.10, with support around 156.65 and 152.18; RSI (14) is near 52.
Market Positioning and Intervention Risks
We see the USD/JPY pair gaining strength near 157.55, fueled by the Bank of Japan’s lack of clear hawkish guidance after its recent rate hike to 1.25%. Derivative traders should position for a near-term upward move toward the 100-day Simple Moving Average at 159.55. However, we must watch the 160.00 level closely, as official intervention risks rise significantly near this mark.
Historical data shows that Japanese authorities are highly sensitive to these levels, having spent a record 9.8 trillion yen in spring 2024 to defend the currency. The recent reports of the central bank conducting “rate checks” serve as a clear warning that they are ready to step in again. We recommend buying short-term USD/JPY put options to hedge against a sudden, government-driven drop in the pair.
Fed Outlook and Trading Strategies
Meanwhile, the U.S. dollar is finding strong support as traders price in a 56.5% chance of a Federal Reserve rate hike in October, up from 43.5% last week. Hawkish comments from Fed officials suggest that inflation risks remain high, keeping U.S. treasury yields elevated. We expect this rate divergence to keep the upward pressure on USD/JPY for the next few weeks.
Technically, the pair is holding steady above the middle Bollinger band support of 156.65. We suggest using bull call spreads to capture the upside toward 159.50 while keeping risk defined. If a sudden intervention pushes the pair down, we should look to accumulate long positions near the major support floor at 152.18.
