“One known unknown uncertainty is over for the market sentiments, however external perils are still bigger headwinds", said Soumyajit Niyogi, associate director, India Ratings and Research Pvt. Ltd .

Investors are also cautious due to higher inflation which fears hike of interest rates by Reserve Bank of India sooner than earlier.

Consumer price inflation rose 4.6% in April faster than the 4.4% of Bloomberg consensus. Wholesale price index (WPI)-based inflation shot up 3.18% in April from a year ago higher than 2.9% median estimate in a Bloomberg survey of 28 economists.

“(Higher inflation) validate our expectations for the RBI policy committee to veer towards a hawkish stance in June (small probability of a pre-emptive hike) and pave the way for a 25bp increase in August. With another move likely in 4Q18, we see room for cumulative 50bp hikes in FY19. Slow progress on the banks’ bad asset resolution and a gradual turnaround in growth suggest that an aggressive hiking cycle is unlikely" said Radhika Rao economist at DBS Bank Ltd.

Analysts also fear that government may not be able to stick to its fiscal deficit target for the year due to surge in crude oil prices and expectations that it may adopt populist measures ahead of the general election next year.
