    USD/JPY fell 0.40% on Monday and traded near 158.60 at the time of writing. It dropped from about 159.60 to an intraday low near 158.25 as the US Dollar weakened. The fall followed US President Donald Trump’s announcement that possible military strikes on Iranian energy infrastructure would be postponed. He cited “productive” discussions aimed at easing tensions in the Middle East.

    Dollar Retreat After Geopolitical Shift

    The US Dollar’s earlier support from safe-haven demand faded after the announcement. The US Dollar Index (DXY) fell to near 99.20 as demand for the Greenback declined. Uncertainty remained after Iran’s Fars News Agency reported there was no direct or indirect communication with Washington. The US Dollar later recovered part of its initial drop. The Japanese Yen kept support from Japan’s policy stance, with officials watching currency moves closely. The Bank of Japan maintained a relatively hawkish bias, and Governor Kazuo Ueda said further rate hikes were possible if inflation matches expectations. Intervention risk increased as USD/JPY traded near levels last seen at the 2024 highs. This helped limit further gains in the pair.

    Near Term Volatility Outlook

    USD/JPY was described as likely to stay highly volatile in the near term. We remember seeing the sharp drop in USD/JPY following the geopolitical easing with Iran back in 2025, which serves as a key reminder of the pair’s sensitivity to safe-haven flows. With the pair now trading much higher, near 162.50, this risk of sudden reversals remains a primary concern for any long positions. The options market reflects this, with one-month implied volatility spiking to over 12% in early March 2026, its highest level in nearly a year. The fundamental picture for the US Dollar is stronger now than it was during that period of uncertainty. The latest US Consumer Price Index data for February 2026 came in at 3.4%, unexpectedly high and prompting the Federal Reserve to signal a prolonged pause in its rate-cutting cycle. This strong interest rate differential provides a solid foundation for the dollar’s value against the yen. However, the threat of intervention from Japanese authorities is now far more acute than it was in 2025. While the Bank of Japan has been less aggressive than anticipated, with core inflation in Tokyo slowing, officials from the Ministry of Finance have issued almost daily verbal warnings against speculative yen selling. Historically, such intense rhetoric has preceded direct market action, especially when the currency weakens this rapidly. Given this backdrop, traders should protect against sharp, sudden moves in either direction. Recent data from the CFTC shows that speculative net short positions on the yen have reached extreme levels not seen since the massive intervention campaigns of 2024, making the trade vulnerable to a painful squeeze. This environment is ideal for purchasing volatility through options, such as buying straddles, which profit from a large price swing regardless of its direction.
