U.S. backs July yen move as stability measure

U.S. Treasury Secretary Scott Bessent has outlined the rationale behind the government’s late-July move to buy Japanese yen in foreign-exchange markets. The intervention came amid significant volatility in the Japanese currency and heightened concern about broader financial-market stability.

Bessent described the action as targeted at addressing disorderly conditions in yen trading rather than at supporting any particular exchange-rate level. He framed the decision as part of a broader effort to limit financial spillovers from sharp currency swings.

Bessent said the U.S. intervention was financed using existing foreign-currency assets held in the Treasury’s Exchange Stabilization Fund. He emphasized that the Treasury did not extend any credit to Japan in the process of buying yen.

As a result, Japan has no repayment obligation to the U.S. Treasury stemming from the late-July operation. The structure of the move underscores that the U.S. drew on its own reserves rather than providing a loan or credit line to Japanese authorities.

Bessent declined to disclose the size of the U.S. deployment in the yen purchases. While details of the exact amount remain undisclosed on the U.S. side, Japanese authorities separately reported record-scale spending over the past month to support their currency.

Bessent warned that extreme or disorderly moves in the yen can have consequences beyond foreign-exchange markets. He highlighted the risk that sharp currency swings could trigger forced unwinds of financial positions among global investors.

Such forced position adjustments, he indicated, could destabilize broader global markets and feed through into higher borrowing costs. In this context, U.S. households and businesses could ultimately face more expensive financing conditions if volatility remains unchecked.

By linking yen volatility to potential pressure on U.S. interest rates, Bessent presented the late-July intervention as aligned with the goal of maintaining orderly market functioning. The focus, he suggested, is on containing cross-border financial stress that might arise from abrupt currency moves.

The Treasury’s explanation places the yen operation squarely within its mandate to support financial stability. Bessent’s comments indicate that U.S. authorities view large, sudden shifts in major currencies as a possible source of systemic risk.

With Japanese officials reporting record efforts over the past month to shore up the yen, the U.S. action forms part of a broader response to heightened stress in the currency. The emphasis on existing reserves, no new credit, and undisclosed deployment size highlights a cautious approach aimed at addressing instability while limiting additional financial commitments.
