The U.S. dollar fell to a three-month low against the euro on August 21 as investors questioned whether the Treasury Department’s expanded bond-buyback program could meaningfully reduce long-term borrowing costs. The policy, designed to support liquidity in longer-dated Treasury securities, instead intensified concerns about U.S. fiscal conditions and a more interventionist approach to bond markets.
The euro rose to approximately $1.1685, near a three-month high, while the dollar index traded close to 98.82. The index, which measures the dollar against six major currencies, was headed for a weekly decline of more than 0.8%.
Treasury Buybacks Put Dollar in Focus
The Treasury Department surprised markets on August 19 by saying it would at least double the maximum size of liquidity-support buybacks for long-dated nominal Treasury securities. Operations covering the 10- to 20-year and 20- to 30-year maturity ranges will increase from $2 billion to at least $4 billion per operation, beginning September 9.
Treasury Secretary Scott Bessent then said the government could raise those repurchases further. He argued that the policy responds to thin trading conditions in the long end of the bond market, particularly during August, and substantial competition from corporate debt issuance.

A Treasury buyback involves repurchasing previously issued bonds. Officials say the program is intended to improve secondary-market liquidity in older, less actively traded securities. It does not directly lower net federal borrowing or change the size of regular Treasury auctions.
Investors Question the Strategy
The market’s initial response was positive: Treasury yields fell sharply and the dollar declined on August 19. But the effect was brief. By August 20, Treasury yields had resumed their rise, with the 10-year yield returning toward 4.70% and the 30-year yield nearing 5.25%.
This reversal suggested that investors viewed the buybacks as a limited liquidity tool rather than a solution to the underlying drivers of elevated yields. Those drivers include large budget deficits, the national debt exceeding $40 trillion, persistent inflation risk and substantial borrowing needs from both the federal government and corporate sector.
Dollar weakness can reflect expectations of lower U.S. yields, but this move also pointed to broader questions about fiscal credibility. Investors may become less willing to hold dollars if they perceive that the government is attempting to manage borrowing costs without addressing spending, deficits or debt-growth pressures.
Euro Gains as Dollar Index Drops
The euro was on track for a weekly advance of roughly 1% against the dollar and a fourth consecutive weekly gain. It later reached as high as $1.1711, a 14-week peak.
The British pound also gained, trading close to $1.3652, as the broader dollar decline benefited major currencies. The dollar’s pullback supported gold and other dollar-priced commodities because it made them less expensive for non-U.S. buyers.
The weaker greenback can help U.S. exporters by improving the price competitiveness of American goods abroad. However, it can also raise the cost of imported goods and materials, potentially adding to inflation pressure.
What Happens Next for the Dollar?
The dollar outlook will depend on whether Treasury yields stabilise, how inflation evolves and whether the administration delivers credible fiscal-consolidation measures. Bessent has indicated that the government intends to announce greater focus on fiscal discipline, but markets will want specifics on revenue, spending and future borrowing plans.
Federal Reserve policy remains another major driver. If inflation remains persistent and the Fed keeps rates high, the dollar could regain support. Conversely, a renewed decline in yields, softer economic data or expanded Treasury interventions could prolong the dollar’s weakness.
For now, the three-month low in the dollar shows that investors are looking beyond short-term bond-market support. They are focused on the sustainability of U.S. borrowing and the policy response to rising long-term interest rates.
