The Japanese yen posted its strongest weekly advance in months after Bank of Japan policymakers signaled readiness to quicken the pace of monetary tightening, catching markets off guard and forcing a rapid repositioning of leveraged carry trades. Traders say the shift reflects growing confidence among BoJ officials that sustainable inflation has finally taken hold, freeing them to pursue more aggressive policy normalization.
Market participants note that the BoJ's February meeting minutes, released Thursday, contained unusually direct language about "addressing accommodative policy without hesitation," a phrase interpreted as laying groundwork for a 25 basis-point move in March. The commentary marks a stark contrast to the gradualist approach that defined 2025, when the central bank delivered only two modest hikes. "The market had grown complacent about BoJ timing," said a senior currency strategist at a major European bank. "This recalibration is forcing a painful exit from deeply embedded short-yen positions."
The unwind has hit USD/JPY particularly hard, with momentum indicators showing the pair breaking below key structural support that had held since November. EUR/JPY and GBP/JPY also declined sharply as hedge funds scrambled to cover leveraged positions, while volatility in yen crosses spiked to levels not seen since the BoJ's surprise policy tweak in July 2023. The ripple effects extended beyond forex, with Japanese equities under pressure and global bond yields adjusting to the prospect of reduced Japanese investment outflows. Gold prices edged higher as the yen's strength weighed on the dollar index, though crude oil remained focused on separate supply dynamics.
Looking ahead, traders are closely watching next week's US CPI data and the ECB's policy account for further clues on divergence dynamics. Technical analysts say yen crosses have entered a new range, with former support levels now acting as resistance. Positioning data suggests the carry trade unwind may have further to run, as speculative accounts remain heavily skewed despite this week's moves. The market's focus now shifts to the BoJ's March 18-19 meeting, where officials will have fresh inflation and wage data to justify their next step.
