Indian government bonds inched up in early deals on Friday, as abating concerns of fiscal slippage from tax revision and higher U.S. Treasuries lifted sentiment. The benchmark 10-year bond yield was at 6.4814% as of 10:00 a.m. IST, compared with Thursday's close of 6.4934%. Bond yields move inversely to prices. Late on Wednesday, India lowered the Goods and Services Tax on hundreds of items to spur consumption. The resulting net revenue loss for federal and state governments is estimated at 480 billion rupees ($5.46 billion), far below market estimates of about 1 trillion rupees.
