The dollar index (DXY00) tumbled to a 2.5-month low today and is down by -0.76%. The dollar retreated today after the US Treasury boosted liquidity and announced plans to increase buybacks of long-dated bonds. Lower T-note yields today have also weakened the dollar‘s interest rate differentials.
The US Treasury announced today that it will at least double the maximum size of its liquidity support buyback operations for longer-dated nominal coupon sizes to at least $4 billion per operation, effective September 9.
