Dollar at three-month low as Treasury moves to soothe bond jitters

The U.S. dollar experienced a slight recovery on Thursday after initially losing ground, as traders assessed the potential effectiveness of the Treasury Department's efforts to curb longer-term Treasury yields. The Treasury revealed on Wednesday plans to double the size of its buybacks of 10- to 30-year debt to a minimum of $4 billion per operation, aiming to stabilize a market shaken by worries over the expanding U.S. fiscal deficit.

This announcement led to a significant sell-off in the U.S. dollar as investors feared that higher long-term yields would not adequately reflect the fiscal situation, resulting in a weaker currency. This phenomenon, known as the "debasement trade," also contributed to the rise of gold and bitcoin as alternative value stores. However, markets swiftly reacted against the Treasury's latest move, with yields beginning to increase again, according to Sarah Ying, head of FX strategy at CIBC Capital Markets.

Treasury Secretary Scott Bessent indicated that the market may witness more such announcements in the future, but the market seems skeptical about their credibility at present. Bessent suggested that he might raise the volume of Treasury bonds repurchased, asserting that yields do not accurately represent underlying fundamentals.

The dollar index, which gauges the greenback against a basket of currencies, including the yen and the euro, climbed 0.06 percent to 98.89, while the euro dipped 0.01 percent to $1.1676. The euro had previously reached $1.171, the highest level since May 14. The Japanese yen weakened 0.6 percent against the dollar to 159.12 per dollar, marking the second currency intervention by Bessent in recent weeks.

Bessent's intervention followed the Treasury's quarterly refunding statement earlier in August and ahead of a 20-year bond auction. Many investors found the timing of the buyback announcement unusual, as it occurred shortly after the Treasury's statement and before the 20-year bond auction. Shaun Osborne, chief FX strategist at Scotiabank, noted that markets concluded that the Treasury intended to prevent bond markets from bearing the burden of fiscal policy sustainability and Federal Reserve policy credibility concerns.

Market participants are also closely monitoring an upcoming speech by Federal Reserve Chairman Kevin Warsh at the central bank's Jackson Hole symposium later in the month, hoping for more concrete insights on how he plans to address persistent inflation.
