Fed Warning and Yen Support Fight Collide Over Rate Path

Treasury Secretary Bessent defended US support for the yen, citing risks the currency's weakness could pose to American borrowing costs. Yen carry trades, where investors borrow cheaply in yen to fund purchases of higher-yielding US assets, are sensitive to shifts in the Federal Reserve's rate path and in the yen's exchange rate. Separately, commentary this week argued that yen carry traders may be positioning for a more aggressive round of Fed rate hikes than markets currently expect, a dynamic that would widen the interest-rate gap the carry trade depends on. That view sits alongside reporting that the Fed has already delivered a cautionary signal to markets about the path ahead. What remains unresolved is whether the Fed's next policy meeting confirms a more hawkish stance or pushes back against the aggressive-hike narrative, and how the yen reacts either way.
