Indian government bond yields ended little changed on Tuesday after a record state debt auction was easily absorbed by the market, while a smaller-than-expected debt purchase by the central bank lifted sentiment. The benchmark 10-year bond yield ended at 6.6370 per cent, compared with its previous close of 6.6291 per cent. Indian states raised Rs 722.55 billion ($8.43 billion) through a sale of bonds, the biggest amount ever to be borrowed via a single auction.
