The dollar index (DXY00) tumbled to a 2.5-month low on Wednesday and finished down by -0.80%. The dollar retreated on Wednesday after the US Treasury boosted liquidity and announced plans to increase buybacks of long-dated bonds. Lower T-note yields on Wednesday also weakened the dollar‘s interest rate differentials.
The US Treasury announced on Wednesday 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.
