Billions of dollars of pre-election spending by the Indian government and political parties in the next two months is unlikely to stop the nation’s economy from slowing further, economists said.

Asia’s third-largest economy lost momentum in the final quarter of 2018 as the annual rate of growth slipped to 6.6 per cent, much lower than expected and the slowest pace in five quarters. But the worst may not be over.

Prime Minister Narendra Modi, who will be seeking a second term in elections due to be held by May, in an interim budget last month introduced populist spending measures worth $25.37 billion and modest tax cuts in the current fiscal year ending March 31 in an attempt to win the votes of farmers and the urban middle class. That is on top of additional spending at the state government level.

The political parties are also likely to spend nearly Rs 500 billion during the election campaign, according to estimates of CMS, a Delhi-based think tank.

But weakening global growth, rising oil prices in recent weeks, slowing growth in government spending on infrastructure and delays in investment decisions because of uncertainty about who will form the next government could more than offset the extra election-related spending.

An expected deceleration in economic growth in major economies around the world, including China and the United States, is expected to hurt trade growth.

“We don’t expect any election-spend related upside to growth for the next two quarters,” said Soumya Kanti Ghosh, chief economist at the State Bank of India, the country’s largest state-run bank.

He said there was an overall slowdown in consumption and government spending on infrastructure and that this could continue until the September quarter. Ghosh is forecasting economic growth could decline to 6.2 per cent in the January-March quarter and below 6 per cent in the June quarter.

The government has played down the risks to the economy. Subhash Chandra Garg, one of the top officials in the finance ministry, said the downward revision of the government’s annual GDP growth estimate to 7 per cent in the current financial year was at least in part due to an upward revision of GDP growth for the previous year to 7.2 per cent.

Growth in consumer spending, which accounts for nearly 60 per cent of the economy, slowed to 8.4 per cent in the October-December quarter, compared with a revised 9.9 per cent increase in the previous quarter.

Policy advisers are worried that the global slowdown could hurt the manufacturing sector — hitting auto, engineering, textile and some other labour intensive sectors.
