Dollar hits 3-month low vs euro, pares losses after Treasury move

U.S. dollar experienced a three-month low against the euro on Thursday, benefiting from a Treasury Department's move to stabilize a bond market selloff. The Treasury Department announced it would double its buybacks of 10- to 30-year debt to at least $4 billion per operation, aiming to calm concerns over the U.S. fiscal deficit and potentially higher inflation.

The dollar index, measuring the greenback against a basket of currencies, including the yen and the euro, fell 0.01% to 98.82, with the euro rising 0.01% to $1.1678. The single currency briefly touched $1.171, the highest since May 14. Japanese yen weakened 0.38% to 158.75 per dollar. Treasury Secretary Scott Bessent's intervention was seen by some analysts as testing the market, with investors concluding that if the Treasury wants to prevent bond markets from bearing the burden of fiscal policy and Fed policy credibility concerns, the dollar will have to stabilize.

Traders are also on edge ahead of Federal Reserve Chairman Kevin Warsh's upcoming speech at the central bank's Jackson Hole symposium for insights on tackling persistent inflation.
