US Yen Intervention Aimed at Avoiding Forced Bond Sales

Treasury Secretary Scott Bessent has defended US involvement in last week's yen intervention, characterizing it as a sign of support for America's allies. However, some analysts see this move as an attempt to mitigate rising borrowing costs and prevent the forced sale of Treasury securities by Japan.

The US joined its Asian ally in boosting the yen to 155.23 per dollar, its strongest level since May. The Japanese currency had been struggling due to low bond yields, concerns over fiscal and monetary policy credibility, and a terms-of-trade shock caused by the US-Iran war, which has significantly impacted Japan's energy imports.

The last time the US intervened in the yen market was 15 years ago, but this is the first instance of supporting the yen. Bessent's justification for the move suggests that the administration is becoming increasingly concerned about its own borrowing costs and wants to avoid a situation where Japan would be forced to sell its massive holdings of Treasury securities.
