Dubai: After posting the best quarter in four years, Indian bonds are pitted against a familiar foe: likely record debt sales by the government to finance populist measures before national elections due by May.

Prime Minister Narendra Modi’s administration may announce plans to borrow Rs6.4 trillion (Dh331.1 billion, $90 billion) on Friday for the next fiscal year in its budget, according to the median estimate of 15 strategists in a Bloomberg News survey. That compares with a revised 5.35 trillion rupees for the current year.

Investors have turned skittish about the health of India’s finances amid signs that the government is ready to sacrifice fiscal discipline as it weighs an aid package to appease farmers, a key voting block. The concerns have led to the yield on the most-traded 2028 bonds rising in four of the past five weeks, with primary dealers rescuing a sovereign debt sale on January 18.

“All pre-poll budgets are oriented toward elections, and markets will react negatively if the budget is heavy on spending and ambitious on revenues,” said Killol Pandya, head of fixed income at Essel Funds Management. “We are positioned more in the shorter-maturity bonds, given that the outlook is not benign due to budget worries.”

Net borrowing, adjusted for repayment of bonds, is seen at Rs4.2 trillion versus Rs3.91 trillion this fiscal year, according to the survey.

While the yield on 2028 bonds fell rapidly in the October-December period as oil slumped and the central bank boosted its debt purchases, it was the Rs700-billion reduction in federal borrowings that first began to buoy the sentiment after a yearlong sell-off.

Worries about higher debt sales have re-emerged just as prices of oil — India’s top import — have begun to recover and revenue from income tax and asset sales is trailing estimates. That’s not all. The budget deficit is seen widening to 3.5 per cent of gross domestic product in the year ending March versus the 3.3 per cent target, according to a separate Bloomberg News survey.

Not surprisingly, the yield on the 2028 bonds has risen 18 basis points in January, the most among the major Asian emerging markets, and global funds have pulled $317 million from local bonds this month.

The benchmark 10-year yield could climb to 8 per cent if the size of the farm-relief package is “substantial and weighs more on the fiscal deficit that what we have pencilled in,” said Hugo Erken, senior economist at Rabobank International. The yield on 2028 bonds fell one basis point to 7.55 per cent on Friday.

Reclaiming the 8 per cent mark — a level seen in October — will “make it difficult for the government to refinance their debt in fiscal 2020,” he said.
