Washington's decision to back the yen with euros rather than dollars shows the dollar's reserve status is cracking as Treasury sales pressure mounts.
The US Treasury used euros rather than dollars to support the yen, a break from convention that shows Washington's concern over its own bond market and the dollar's eroding reserve status. The operation, which the Financial Times reported "blindsided" the European Central Bank, was not informed until after the intervention.
"The dollar's status as a reserve currency is not what it used to be," Barry Eichengreen, an economist at the University of California, Berkeley, argued in the Financial Times. He said Treasury Secretary Scott Bessent and other US officials may have worried that selling dollar securities to support the yen would put additional pressure on the long end of the Treasury market.
Japan's own intervention has already drained its reserves. Its foreign currency reserves fell by $75.6 billion in May, an amount Bloomberg reported broadly matched the scale of yen intervention that month, while Federal Reserve custody data showed a decline in Japanese Treasury holdings consistent with liquidation. The dilemma is acute for Washington: more Treasuries hitting the market can push prices lower and yields higher precisely when the federal government needs to borrow enormous sums — it already spends more than $1 trillion per year on interest alone.
The stakes extend beyond the yen. If the yield on the 10-year Treasury is 3.5 percent instead of 2.5 percent, the federal government must pay more to borrow, a burden that compounds as the US runs persistent deficits. Japanese officials have indicated they will use the Federal Reserve's Foreign and International Monetary Authorities (FIMA) Repo Facility for future currency-support operations, a mechanism created in March 2020 that lets foreign central banks pledge Treasuries as collateral for dollars rather than sell them outright.
The shift toward the FIMA facility points to a deeper de-dollarization story. Central banks traditionally hold dollar reserves partly because the Treasury market is deep and liquid, allowing those assets to be deployed in currency interventions. But if foreign central banks face pressure not to sell their Treasury holdings because Washington is worried about the effect on its own bond market, the question becomes why hold reserves at all.
Eichengreen warned that other countries could intensify their search for alternatives, accelerating reserve diversification. Gold is one obvious beneficiary. Capital Economics economist Kieran Tompkins argued that concerns about central banks conducting foreign-exchange operations without upsetting US officials over Treasury-market consequences could provide fresh impetus for central bank gold demand, a pillar that has helped bullion hold around the $4,000 level despite interest-rate headwinds and subdued Western investor enthusiasm.
The dollar's strain runs parallel to a renewed political fight over America's gold. Treasury Secretary Scott Bessent had insisted all the gold at Fort Knox was present and accounted for, despite acknowledging he had not personally visited the facility. Sen. Rand Paul then toured the US Bullion Depository and declared the gold was there — approximately 147 million ounces.
Skeptics were not persuaded. Money Metals Exchange host Mike Maharrey noted that based on the amount of gold the government says Fort Knox contains, there should be more than 300,000 gold bars inside, many of them irregular weights from coins melted down after the gold policies of the 1930s. Money Metals CEO Stefan Gleason argued that a brief guided visit cannot establish that America's gold is fully accounted for, and noted 83 percent of the gold is unacceptable on global markets due to insufficient purity.
Paul co-sponsored the Gold Reserve Transparency Act of 2025 with Sen. Mike Lee, legislation that would have provided for a full audit of US gold reserves. A proper independent examination would require every bar counted and inspected, serial numbers reconciled with official records, and gold assayed to verify weight and purity — plus published documentation addressing chain of custody and whether any metal has been loaned, pledged, or encumbered.
The last time officials opened the Fort Knox vaults to outsiders was 1974, an episode Maharrey characterized as a publicity event rather than rigorous accounting. The continuing resistance to an independent audit only breeds suspicion, he argued, comparing it to a private company that refused to audit its books.
The two threads converge on the same theme: the dollar's international position is showing strain as the US struggles to preserve demand for Treasury securities, while Washington continues asking Americans to accept assurances about the nation's gold holdings without the kind of published audit that would settle the question. Maharrey pointed to the long-running erosion of purchasing power, saying government policy is effectively designed to devalue money by more than 10 percent every five years. The dollar may remain the world's dominant reserve currency for some time, but as he put it, "the dollar is not what it used to be."
