The Rupee opened stronger on Thursday, after the dollar slid to a three-month low following the U.S. ?Treasury's move to boost buybacks of longer-dated bonds to alleviate pressure on ?the bond market. The dollar index fell 0.88% ?on Wednesday, posting its biggest daily decline since mid-March, after the U.S. ?Treasury unveiled plans to double the size of its liquidity-support operations for longer-dated ?bonds.
