Bessent attacks Warren over yen intervention query, offers ‘Foreign Exchange for Dummies' lesson

• Warren's letter contained an opening error suggesting Japan owed Treasury money, though she later correctly described the transaction as a euro-for-yen sale with no credit extended to Japan
• Bessent did not disclose critical details including how much yen was purchased, the execution rate, or the position's current value, despite his notepad showing '$5-10 bil' at a July 31 meeting
• The intervention marked the first coordinated U.S.-Japan currency support effort since 1998, with Japan spending a record 15.4 trillion yen ($96.5 billion) between July 30 and August 26

Summary

Key Development: Treasury Secretary Scott Bessent publicly attacked Senator Elizabeth Warren over her inquiry into U.S. intervention to support the Japanese yen, though he left several of her questions unanswered.

The Dispute: Bessent criticized Warren for what he termed a "remedial error" in understanding foreign exchange markets, offering a "Foreign Exchange for Dummies" lesson. Warren's letter initially suggested Japan could owe Treasury money, though she later correctly described the transaction as a euro-for-yen sale. Warren responded by citing Bessent's recent policy setbacks.

Transaction Details: Treasury sold euros from its Exchange Stabilization Fund to purchase yen after the Japanese currency hit record lows. Bessent clarified no congressional appropriation was involved and Japan owes Treasury nothing. However, he declined to disclose critical information including the purchase amount (though his notepad showed "$5-10 bil"), execution rate, or current position value.

Historical Context: This marked the first coordinated U.S.-Japan currency intervention since 1998. Japan spent a record 15.4 trillion yen (approximately $96.5 billion) supporting its currency between July 30 and August 26.

Rationale: Bessent defended the intervention as necessary to protect U.S. economic interests, arguing a disorderly yen could impact inflation and raise U.S. borrowing costs.

Unanswered Questions: Bessent did not confirm whether the European Central Bank was consulted before the euro sale or provide the detailed legal justification Warren requested.

Market Implications: The public dispute highlights transparency concerns around unprecedented currency interventions and their potential impact on U.S. monetary policy and international financial relationships.
