The yen hovered around the critical ¥160 level after BoJ officials flagged exchange-rate risks, the Tankan survey revised firms' USD/JPY expectations higher, and Tokyo escalated intervention rhetoric. Markets priced a meaningful chance of a BoJ rate hike while crude and macro data added pressure.

USD/JPY has been volatile as the yen stays under pressure from structural flows and BOJ policy divergence. This week’s modest Tankan improvement, looming trade and export data, and Tokyo’s stepped-up intervention rhetoric—plus a flash spike to 160—kept traders on edge. The article explains the concrete drivers, the limits of verbal warnings, the technical significance of 160, and practical trading responses.

A concise review of last week’s concrete drivers behind yen moves: IMF data showing a mid‑March yen uptick toward ¥158, MUFG’s revised 2026 USD/JPY forecasts indicating gradual yen appreciation, snap election–related volatility, and higher oil pushing import costs. The article explains how each factor has pushed USD/JPY into the ¥157–159 range and what traders should watch next.

The yen weakened this week as USD/JPY pushed toward 158 after Japan’s finance minister issued verbal intervention warnings and Middle East tensions lifted oil prices. The combination of geopolitical risk and policy divergence keeps intervention risk elevated and technical resistance in focus.

USD/JPY hovered around 155–156 last week as political shifts, fading BoJ hawkish bets and renewed talk of exchange-rate reviews drove heightened yen volatility. Traders are watching the 155 level for possible official action while short-term forecasts and bank outlooks point to gradual yen recovery later in 2026.

Over the past week the yen weakened after Prime Minister Sanae Takaichi named dovish BoJ board candidates, Japan's CPI cooled below target, and reports surfaced of U.S. “rate checks” — all combining to push USD/JPY higher and elevate intervention risk. This article breaks down the events, explains their direct impact on USD/JPY, and outlines practical trading implications.
