Fed's June Rate Hold Extends Yen Weakness via Widening Yield Gap

The Federal Reserve held the federal funds rate at 3.50–3.75 percent on June 17, 2026, maintaining the yield advantage that fuels carry trades in the yen. When US assets pay significantly more than yen-denominated ones, traders borrow cheap yen to buy higher-yielding dollar instruments—a trade that weakens the currency. Each Fed pause delays the rate cuts that would narrow this gap, keeping structural pressure on the yen and forcing Japan's hand on potential currency intervention.
