Bessent warns traders against betting on yen weakness. Treasury Secretary Scott Bessent issued his most strident warning yet to currency traders betting against the yen. It follows July's rare joint U.S.-Japan intervention -- with implications for U.S. stocks and bond yields.

In remarks reported by MarketWatch, Bessent framed the government's posture with the phrase "I am the house now," suggesting the Treasury is prepared to keep defending the Japanese currency after the joint action taken with Tokyo in July. The outlet reports the episode's consequences extend beyond foreign exchange, reaching into American equity markets and Treasury borrowing costs, though the material does not detail how those effects would unfold.
