Japan's prime minister says her policies will boost confidence in the yen after U.S. intervention falls short

• Takaichi told President Trump that yen undervaluation is a problem and aims to strengthen competitiveness through investments in crisis management and growth areas rather than direct currency manipulation
• Current market pricing suggests investors expect further intervention, with strategists warning that intervention alone is unlikely to deliver sustained recovery without domestic policy changes
• Yen weakness has driven up Japanese import costs and inflation, with concerns that continued weakness could prompt Japan to sell down its Treasury holdings (the largest foreign holder of U.S. debt)

Summary

Japanese Prime Minister Sanae Takaichi stated Thursday that her government's economic policies will strengthen market confidence in the yen after previous intervention efforts, including U.S. support, proved insufficient. Takaichi told President Donald Trump last month that the yen's undervaluation poses a significant problem.

Key Developments

The yen remains weak despite being the G10's best-performing currency in Q3, gaining 3.3% against the dollar. Currently trading at 158.37 yen per dollar (as of 5:57 AM ET Thursday), the currency has declined approximately 7.65% over the past year, down from a July peak above 163.

Takaichi emphasized her administration's focus on boosting Japan's growth potential through investments in crisis management and strategic sectors rather than direct currency manipulation. She stated these efforts would enhance Japan's global competitiveness and restore yen confidence.

Market Implications

Analysts at Societe Generale note strong market expectations for additional USD/JPY intervention, with investors positioning cautiously to avoid being caught off-guard. However, OCBC strategists warn that "intervention alone is unlikely to deliver a sustained recovery without support from domestic policy changes."

Yen weakness presents multiple challenges for policymakers: elevated import costs, rising inflation, and pressure on government bond yields. Critics link Takaichi's spending plans to currency pressure. U.S. officials are reportedly concerned that continued yen weakness could prompt Japan—the largest foreign holder of U.S. Treasuries—to sell holdings.

Takaichi committed to maintaining spending levels consistent with lowering Japan's debt-to-GDP ratio while "appropriately managing" bond issuances to meet fiscal needs.
