The $1.2 Trillion Reason Scott Bessent Just Bought Japanese Yen

The article says the U.S. Treasury, under Scott Bessent, bought Japanese yen for the first time since 2011, reportedly in a $5 billion to $10 billion intervention, to support a currency near 40-year lows. The move is framed as more than FX management: a weaker yen can pressure Japanese holders of U.S. Treasuries to sell, which would push Treasury yields higher and, by extension, raise mortgage, auto-loan, and credit-card borrowing costs in the U.S. The article argues that stabilizing the yen may help reduce upward pressure on long-term U.S. rates by preserving demand for Treasuries. Japan also reportedly used the Fed’s repurchase facility for dollar liquidity instead of selling Treasuries outright, limiting yield pressure. Overall, the piece highlights how FX intervention in Japan could have knock-on effects across U.S. bond markets and household borrowing costs.
