The country's economic rebound, already weakened in recent months, could lose further momentum as coronavirus variants pose the greatest threat and inflation rises, a Reuters poll of economists found.
The latest survey results suggest difficult policy decisions lie ahead for the Reserve Bank of India, which has already seen two consecutive months of inflation above the six per cent upper limit of the range it tolerates.
The RBI said last week that prospects for the economy had brightened and the inflation rise would be transitory, echoing the views of most major central banks.
But the fast spread of the Delta variant in some states - and it is becoming dominant around the world - has raised doubts as the country contends with a devastating wave of COVID-19.
The July 15-22 poll of 52 economists showed a third consecutive downgrade to the growth outlook for the current fiscal year 2021-22, but also the third such upgrade to the following year.
About two-thirds of economists, or 23 of 36, who responded to an extra question said virus variants were the biggest risk, while only a handful cited high inflation.
"Resurgence in cases and (any) emergence of fresh variants are notable risks for the economy for the rest of the year, particularly at a time when vaccination coverage is short of achieving a critical mass," said DBS economist Radhika Rao.
"Reinstatement of movement curbs risks deepening the damage inflicted on the informal sector, which contributes to nearly half of the national output and employs a majority."
A separate Reuters survey of global health experts last month concluded another wave of infections and COVID-19 in India was likely by October.
After contracting in the previous fiscal year at its fastest annual pace since records began over four decades ago - one of the worst-hit in Asia, the economy was predicted to expand 9.4% in the current fiscal year. The last time the economy grew that quickly was in 2010.
The latest consensus forecast was a downgrade from 9.8 per cent in the previous poll in May, itself down from 11.0 per cent in April, and slightly below the RBI's latest projection of 9.5 per cent.
Asked for their worst-case scenario this fiscal year, economists provided a median seven per cent, in a five per cent- nine per cent range. Growth in any case was expected to slow to 6.9 per cent in fiscal 2022-23.
Although inflation was forecast to ease from 6.3 per cent at the last measure, the consensus was for it to average above the mid-point of the RBI's medium-term target of two per cent-six per cent at least until early 2023.
Inflation was predicted to average 5.5 per cent and 4.7 per cent in the current fiscal year and next, up from five per cent and steady with 4.7 per cent predicted in May. For now, the RBI is expected to keep its policy rates unchanged as inflation appears to be coming off a peak.
But the consensus pointed to two 25 basis point hikes each next fiscal year, taking the repo rate to 4.50 per cent by end-March 2023, with 32 economists now predicting at least one hike by early that year compared with 24 in the previous poll.
"Despite the growth concerns, we think the RBI will eventually need to act to bottle the inflation genie so as not to lose control. We therefore expect monetary policy normalisation to start relatively soon," noted Kunal Kundu, India economist at Societe Generale.
"However, with a third wave of the pandemic appearing to be a certainty, with experts pointing to the less than desirable pace of vaccination, the precise timing of normalisation remains uncertain."
