Treasury Used Euro Reserves in July Yen Intervention

The New York Fed reported on Nov. 12 that the U.S. Treasury used euros from its Exchange Stabilization Fund to buy 79.4 billion yen on July 31. The transaction involved existing foreign-currency reserves, not newly created dollars.

The New York Fed conducted the spot-market trade as the Treasury’s fiscal agent. Treasury used the purchase to counter what officials considered disorderly movements in the yen. The Federal Reserve did not intervene in foreign-exchange markets during the third quarter of 2026.

Treasury’s foreign-currency assets include euros and yen. The New York Fed conducts foreign-exchange transactions for the department when authorized.

A separate Federal Reserve facility provides temporary dollar funding to foreign central banks through currency swaps. The amount outstanding through those arrangements fell from $250 million on June 30 to $207 million on Sept. 30. The Bank of Japan had no outstanding balance at the end of September. The European Central Bank and the Bank of England held the remaining balances.

The quarter-end figures do not show the total borrowing during the quarter or establish dollar-funding conditions in November. The report described borrowing premiums in major currency pairs as generally low during the third quarter.

A stronger yen can affect leveraged investors that borrowed yen to finance positions in other assets. Repaying those loans becomes more expensive when the yen rises. Higher volatility can also lead lenders to demand more collateral, prompting investors to sell assets or reduce leverage.

The Bank for International Settlements has reported that leveraged equity and currency positions intensified the market shock in August 2024. Higher margin requirements led to further reductions in leverage during that episode. International Monetary Fund research has linked tighter U.S. monetary policy with lower prices across a broad crypto-market factor through weaker risk appetite.

The New York Fed report does not identify Bitcoin purchases, current crypto-market flows or a present yen-funded liquidation. A Bank of Japan exchange-rate sheet listed the dollar at 159.70 to 159.71 yen at 5 p.m. local time on Nov. 12. That figure was a market observation, not an announced intervention threshold.
