US Treasury Joins Japan in First Joint Yen-Buying Intervention in Over a Decade

Sourced from 4 publications

  • The US Treasury's joint yen-buying intervention with Japan is the first such collaboration in more than a decade, per CNBC and the Financial Times.
  • A photographed 'to-do list' belonging to Treasury Secretary Bessent showed a proposal to buy $5 billion to $10 billion in yen, according to Reuters.
  • The yen had fallen to 40-year lows, stoking domestic inflation in Japan and creating trade friction with the US.
  • The yen's depreciation and Japan's resulting trade advantage is a growing source of irritation for President Trump, the Business Times reports.
  • Japan may have independently sold approximately $58.97 billion to support the yen, according to estimates cited by CNBC.

What Happens Next

  • Carry traders with large short-yen positions face margin pressure and forced unwinds, amplifying near-term yen volatility rather than dampening it.
  • A stronger yen compresses profit margins for major Japanese exporters (Toyota, Sony, Hitachi), likely triggering downward earnings revisions for FY2025 guidance.
  • The $5-10 billion US commitment signals Washington's willingness to use currency tools as trade leverage, increasing pressure on Japan to make concessions in parallel trade negotiations.
  • Japan's domestic import costs decline with a stronger yen, easing food and energy inflation that had been politically destabilizing for the ruling LDP.

Near-term: Within 1-3 months, forced liquidation of short-yen carry trades drives sharp position adjustments across G10 FX pairs, with particular impact on yen-funded emerging market positions. Long-term: Over 2-5 years, the precedent of joint US-Japan currency intervention re-establishes coordinated FX action as an active policy tool among G7 nations, increasing the political management of exchange rates relative to market-driven pricing.
