Many analysts, however, did not share the finance minister's optimism. ? There is unlikely to be any significant positivity for the bond yields in the near future with the inflation numbers still failing to come off in a significant way,? Kotak Mahindra Bank chief economist Indranil Pan said in a note. The bank expects the RBI to hike the repo rate by 25 basis to 8% at its mid-quarter review in December. The relatively high level of yields on benchmark bonds like the 10-year government bond has pushed up the cost of borrowing for the government and has also led to an increase in corporate borrowing costs in the market. So far in 2013-14, the rise in bond yields has rendered the cost of borrowing 10-year money for the government dearer by a whopping 100 basis points. The government borrowed Rs 3.49 lakh crore through bonds during April-September and is slated to borrow Rs 2.35 lakh crore during October-March.
