The US Dollar weakened significantly, reaching its lowest level since May, following the US Treasury's announcement to expand long-end bond buybacks. The Treasury will increase the size of its longer-dated buyback operations from USD2bn to at least USD4bn during the next refunding quarter, spanning from September 9 to November 4 [1]. This move, announced by Treasury Secretary Scott Bessent, aims to ease bond yields, with the Dollar Index (DXY) dropping nearly 0.9% on Wednesday to test support at 98.75, a three-month low [2]. The initiative is seen by Deutsche Bank's George Saravelos as a 'soft-form financial repression policy' designed to contain the long end of the US yield curve, which is negative for the Dollar. Saravelos notes that if US Treasury prices are prevented from adjusting lower, the adjustment burden shifts to the currency, resulting in a weaker Dollar [2].
The buyback announcement led to a 10bp drop in longer-dated US yields, which supported equities and weighed on the Dollar, particularly against high-beta currencies such as the Norwegian krone, New Zealand dollar, and Swedish krona [3]. ING's Chris Turner highlights that the intervention was warmly received by investors, reducing key threats to risk assets and supporting carry trade strategies [3]. Technical analysis indicates that the DXY is in bearish territory, with momentum indicators oversold, suggesting potential for consolidation or a bullish correction. Support is currently at 98.75, with further downside possible to 98.00 if risk assets continue to rally [2][3].
Market attention has shifted back to the Federal Reserve, with the July FOMC minutes showing policymakers discussing further rate hikes but not concluding that near-term tightening is warranted [1][2][3]. Economic data since the July meeting has reduced the urgency for additional policy tightening [1]. ING notes that the FOMC minutes were not particularly hawkish, and short-dated US yields fell 5bp after their release, reinforcing a 'Risk-on, Dollar-off' environment [3]. The next key event is Fed Chair Warsh's speech at the Kansas City Fed's Jackson Hole symposium next week, with OCBC strategists expecting no notably hawkish message and the Fed likely to remain on hold, keeping the USD under pressure in the near term [1].
Structural forces pushing yields higher, such as substantial AI-related financing needs, persistent fiscal deficits, and rising JGB yields, remain in place, but the Treasury's actions are expected to restrain further increases in long-end yields for now [1]. The broad-based USD weakness has revived concerns about currency debasement, supporting demand for gold and the Swiss franc [1].
CONCLUSION
The US Treasury's expanded buyback operations have triggered a sharp decline in the US Dollar, with DXY testing key support levels and equities benefiting from lower yields. Analysts expect the Dollar to remain under pressure in the near term, especially as the Fed appears likely to stay on hold. Market participants are now focused on upcoming Fed communications, while technical and structural factors suggest further downside risk for the Dollar.
