Stronger-than-expected US CPI (0.4% MoM headline, 0.3% core vs 0.2% forecast) and hawkish Fed remarks push markets to fully price a December hike, widening the rate gap over Japan's 1.25% policy rate. USD/JPY trades at 159.13, up 0.24% and the highest since September 2, with 160 in sight. Intervention risk at 160 is the main brake.

Catalysts
  • ▲ October US CPI beat forecasts, released Tuesday
  • ▲ Markets price 88.5% chance of a December hike, 11.5% chance of 50 bps
Risk Factors
  • ▼ Possible Japanese currency intervention near 160, as on July 30 with a record ¥7.98 trillion
  • ▼ Finance Minister Katayama warned authorities would act against speculative moves

With Japan's policy rate at 1.25% versus the Fed's 3.75%-4.00%, and markets now fully pricing a December Fed hike plus three more hikes by mid-2027, the widening rate gap weighs on the yen. It was the weakest major currency on the day, down 0.24-0.31% against USD, EUR and CHF. Intervention risk is the counterweight.

Catalysts
  • ▼ US CPI beat forecasts, boosting Fed hike bets for December
  • ▼ Interest rate gap of roughly 2.5 percentage points in the US's favour
Risk Factors
  • ▲ Japan has intervened several times this year, including a record ¥7.98 trillion on July 30
  • ▲ Finance Minister Katayama warned against disorderly or speculative currency moves

The October CPI beat (0.4% headline, 0.3% core vs 0.2% forecast) plus hawkish comments from Waller, Logan, Paulson and Bowman have markets fully pricing a December hike, lifting the dollar broadly. DXY trades around 102.50, near the year-to-date high of 102.94 reached in October. A softer-than-expected future CPI print would reverse this.

Catalysts
  • ▲ October CPI beat: 0.4% MoM headline vs 0.3% forecast, 0.3% core vs 0.2% forecast
  • ▲ Fed officials back further tightening; December hike fully priced
Risk Factors
  • ▼ Headline CPI pace slowed from 0.6% in September to 0.4%
  • ▼ Further hikes are already largely priced in, limiting upside surprise
