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

The US dollar hit a three-month low on Thursday, Aug 20, as the Treasury Department took steps to ease concerns in the bond market. The dollar index fell to 98.558, its lowest since May 14, while the euro reached a high of US$1.1710. The Treasury's move to increase buybacks of Treasury securities with maturities between 10 and 30 years aimed to reassure markets and reduce concerns about long-term bond sell-offs.

This development came amidst a sharp decline in global bond markets due to worries about soaring government debt and rising oil prices following the ongoing US-Israeli conflict with Iran. The 30-year Treasury yield surged to a 19-year high of 5.337 percent, signaling investor caution. Shaun Osborne, Scotiabank's chief FX strategist, highlighted that if long-term yields cannot withstand these concerns, the dollar may face further depreciation.

The Federal Reserve's recent inflation concerns and fiscal policy sustainability have also contributed to this trend. Meanwhile, the Jackson Hole Symposium, where the Fed's policy outlook under new Chair Kevin Warsh will be discussed, could provide further insights. The yen benefited from the dollar's weakness, while the British pound and Swiss franc remained relatively stable.
