The pair touched 159.94, its highest in over two months, but Japan's top currency diplomat Atsushi Mimura said moves were too fast and referenced the record ¥15.4 trillion spent buying Yen between July 30 and August 3, putting intervention risk back in focus. MUFG/BTMU say the rhetoric should limit further upside beyond 160.00. However, fully priced December Fed hike bets keep broad USD strength, making a reversal difficult.

Catalysts
  • ▼ Japanese intervention warning by top currency diplomat Mimura on Thursday after 159.94 high
  • ▼ Weekly US jobless claims later Thursday and Friday's PPI as Fed December decision clues
Risk Factors
  • ▲ Traders fully price a December Fed rate hike (25 bps most likely, small chance of 50 bps), keeping USD supported
  • ▲ MUFG/BTMU note it is even more difficult to reverse the upward USD/JPY trend while the USD strengthens broadly

The Dollar Index reached 103.08, its highest since April 2025, as traders fully price a December Fed rate hike of 25 bps (with a small chance of 50 bps) after hotter-than-expected US consumer inflation data and Fed officials calling for further hikes. A modest pullback on Thursday to around 102.88 only partially offsets this strength.

Catalysts
  • ▲ Traders fully price a December Fed rate hike after hot US CPI earlier this week
  • ▲ US Dollar Index hit 103.08, highest since April 2025
Risk Factors
  • ▼ A modest USD pullback on Thursday lifted the Dollar Index off its peak
  • ▼ Aggressive positioning leaves the Dollar sensitive to softer jobless claims or PPI prints
