USD/JPY fell 2.25% on Thursday after reversing sharply within hours. It rose to about 160.75 in early London trade, then dropped to 155.55, a move of roughly 500 pips, and later traded near 156.65.
The peak-to-trough move was 3.22%, the steepest one-day fall in more than three years. The decline ended an April rise from the mid-150s and left a daily candle with a long upper wick.
Intervention And Market Reaction
Japanese officials issued warnings during the day, and Nikkei reported that the Ministry of Finance and the Bank of Japan conducted Yen-buying and Dollar-selling intervention. The report described it as the first such action since the 2024 episode that used about $62 billion.
Rate settings were cited as Fed 3.50% to 3.75% versus a BoJ policy rate of 0.75%. Next week includes Tokyo CPI after Thursday’s close and three holidays: Constitution Day (Saturday), Greenery Day (Sunday), and Children’s Day (Monday).
Other scheduled items are Wednesday’s Labour Cash Earnings and the BoJ meeting minutes. In the one-hour chart, USD/JPY was 156.66, with resistance noted at 160.30.
Strategy Considerations For Higher Volatility
Given the sharp intervention, we should prepare for a period of extreme volatility in USD/JPY. The 3.22% single-day swing has caused implied volatility on yen options to spike, which we saw happen after similar interventions in late 2022. This suggests that buying options strategies like straddles, which profit from large price moves in either direction, could be prudent to capture the erratic price action expected in the coming days.
The fundamental conflict between Japanese intervention and global interest rate policy remains the key issue. When we look back at the interventions of 2024, which cost Japan over $60 billion, we recall they only provided temporary relief for the yen because the Federal Reserve’s policy rate was significantly higher. With the current Fed rate at 3.50-3.75% versus the Bank of Japan’s 0.75%, the incentive for carry trades that sell the yen remains powerful, meaning this engineered yen strength may not last.
Next week’s thin holiday schedule in Japan creates a risk of sharp, unpredictable moves, while the US Non-Farm Payrolls report looms as a major catalyst. We know recent US job growth has been moderating, with the latest figures showing 175,000 jobs added in April 2026, but core inflation remains sticky at 3.6%. A strong payrolls number would reinforce the Fed’s higher-for-longer stance and could see USD/JPY snap back toward 160, making short-dated call options an attractive tactical play.
From a technical perspective, the area around 160.30 now acts as a formidable resistance level. We should consider this a key zone for selling call option spreads, as any rally will likely struggle to overcome the point of the intervention. On the downside, the lack of clear support means buying put options could be a way to hedge against another aggressive push lower by Japanese authorities, especially if the US data shows signs of weakness.
