As of October 7, 2025, USD/JPY surged to 150.42, marking a sharp reversal from earlier in the week and reaching a two-month high. The primary catalyst is the dramatic weakening of the Japanese Yen following Sanae Takaichi’s victory in the Liberal Democratic Party (LDP) leadership race on October 5, positioning her as Japan’s next prime minister. Takaichi’s hawkish stance on defense and economic policy has raised political stability concerns, driving JPY selloffs and overshadowing the Bank of Japan’s (BoJ) hawkish signals. Simultaneously, the US Dollar remains resilient despite soft labor data, supported by risk-on flows and stable Fed terminal rate expectations. With widening US-Japan yield spreads and renewed carry trade appeal, the USD/JPY bias is firmly bullish.
Market Overview
Key Drivers: Japanese Yen Weakness
- Political Catalyst:
- Sanae Takaichi’s LDP leadership victory has introduced uncertainty regarding Japan’s fiscal and monetary policy direction.
- Her hawkish economic stance, emphasizing fiscal stimulus and defense spending, has fueled concerns about delayed BoJ tightening amid rising debt issuance.
- Markets are pricing in a prolonged dovish stance by the BoJ, with rate hikes potentially delayed into late 2026.
- Yield Spread Dynamics:
- The US-Japan yield spread widened to ~3.0% as Japanese Government Bond (JGB) yields remain constrained by BoJ policy divergence.
- US Treasury yields remain elevated despite soft Non-Farm Payroll (NFP) data, maintaining the Dollar’s yield advantage.
- Global Yen Weakness:
- Broader JPY selloffs are evident across other pairs (EUR/JPY +1.5%), reflecting diminished safe-haven demand for the Yen amid risk-on sentiment.
US Dollar Resilience
- Mixed US Data:
- September NFP (98k jobs added) disappointed expectations but was offset by steady weekly jobless claims (225k).
- ISM Services PMI dipped to 51.2 but remains above contractionary levels, while core CPI previews suggest stable inflation at 0.2% MoM for October.
- The resolved US government shutdown on October 2 has reduced fiscal risks, bolstering USD sentiment.
- Fed Policy Outlook:
- Fed futures now price a 50bps rate cut in November but keep the terminal rate steady at 3.25%, signaling confidence in long-term economic resilience.
- Despite soft labor data, risk-on flows into equities (S&P 500 +0.8%) and carry trades support USD strength.
- Geopolitical Context:
- Middle East tensions persist but are overshadowed by Japan’s political developments, further reducing demand for JPY safe-haven flows.

- Delayed BoJ tightening would exacerbate yield differentials in favor of USD.

- Positive surprises in upcoming US core CPI or Fed minutes could reinforce USD strength.

- Narrowing polls between Trump and his Democratic rival could increase political uncertainty, pressuring the Dollar.
Actionable Recommendations

Event-Driven Opportunities
- Post-Takaichi Reaction Fade (October 7-8):

- A more dovish tone from the Fed could lead to temporary USD weakness; consider scaling back long positions near resistance zones.
Conclusion
The USD/JPY rally to 150.42 reflects a confluence of factors: Yen weakness driven by Japan’s political uncertainty under Takaichi’s leadership, resilient US Dollar fundamentals, and widening yield spreads favoring carry trades. Technicals align with this bullish narrative, with a breakout above key resistance levels signaling further upside potential toward 151.50 in coming sessions. While risks such as BoJ intervention or shifts in Fed policy remain, the default path for USD/JPY remains higher in the near term.
