USD/JPY
Bullish 🤖 85%
⚡ Intraday 🌍 GLOBAL · Explicit

The pair jumped 0.54% to around 159.65, a ten-week high, after core US CPI rose 0.3% in October versus a 0.2% forecast and Fed's Waller flagged a possible half-point hike in December. Markets now price 85% odds of a December hike and 60% odds of another in January, keeping the dollar strong. The main counterweight is intervention risk as price approaches 160.

Catalysts
  • ▲ Core CPI +0.3% in October vs 0.2% expected; headline +0.4% vs 0.3% expected
  • ▲ Waller's warning a half-point hike may be needed in December if core inflation stays at or above 0.3%
Risk Factors
  • ▼ Approach of the 160.00 level raises the prospect of Japanese yen intervention, per MUFG
  • ▼ Overbought RSI near 72 hints momentum may be stretched
USD
Bullish 🤖 85%
⚡ Intraday 🌍 US ✨ Inferred

Hot US October inflation (core +0.3%, headline +0.4%, both above forecasts) plus Waller's warning of a possible half-point December hike sharply repriced Fed expectations to 85% odds of a December hike and 60% of a January move, reinforcing dollar appeal. Risk: further hawkish pricing is already partly in the price.

Catalysts
  • ▲ October CPI beat (core 0.3% vs 0.2% expected, headline 0.4% vs 0.3%)
  • ▲ Waller: half-point hike may be needed in December
Risk Factors
  • ▼ Markets already assign 85% probability to a December hike, limiting further repricing room
  • ▼ BoJ tightening expectations could eventually narrow the policy gap
JPY
Bearish 🤖 75%
⚡ Intraday 🌍 JP ✨ Inferred

The yen fell to a ten-week low as the dollar surged on hawkish Fed repricing, even though the BoJ's October Summary of Opinions showed growing support for more tightening. Policy divergence favours the dollar, though intervention above 160 and possible BoJ tightening cap the downside.

Catalysts
  • ▼ Yen weakened sharply after the US inflation data, per MUFG
  • ▼ BoJ October Summary of Opinions shows increasing support for tightening
Risk Factors
  • ▲ Japanese authorities may intervene as USD/JPY nears 160
  • ▲ Stable inflation at 2.00% could lead the BoJ to rein in accommodative policy, supporting the yen over the medium term
