The Reserve Bank of India has already cut interest rates by 110 basis points this year.

Infrastructure output grew at the slowest pace in more than four years

Country's prolonged consumption slowdown and a deteriorating global environment are delaying a recovery in Asia's third-largest economy, nudging its government into action to supplement the central bank's monetary stimulus.

In a spate of announcements within the space of a week, the government eased foreign investment rules, gave concessions on vehicle purchases and encouraged banks to make loans cheaper to spur growth from a five-year low. It also secured more fiscal space to stimulate the economy with a windfall from the central bank in excess of $24 billion.

Data due Friday is expected to show gross domestic product growth slowed for a fifth straight quarter to 5.7 per cent in the three months ended June. That's slower than the 5.8 per cent expansion in the previous quarter.

While the slowdown last quarter reflects, for the most part, a slump in investment before the election, high-frequency indicators since then suggest the economy's lack of momentum has persisted.

Finance Minister Nirmala Sitharaman is still considering whether to use the windfall from the central bank to cut borrowings or boost spending. The other measures announced so far, like the easing of foreign investment rules, will also do little to boost consumer demand in the near term.

"Since the major contributors to the economy's investment pie are households and private corporations, their spending hold the key for reviving broad-based investment activity in the economy," said Sunil Kumar Sinha, principal economist at India Ratings and Research, the local arm of Fitch Ratings.

Unemployment is at a 45-year high, car sales have slumped the most in almost two decades in July and infrastructure output grew at the slowest pace in more than four years.

The Reserve Bank of India has already cut interest rates by 110 basis points this year to the lowest in nine years to boost loans and revive investment, while signaling it's ready to do more. It has been pumping in liquidity to tide over a cash crunch in the banking sector.

What Bloomberg's Economists Say

"India's slowdown is taking longer than anticipated to turn around, with the slump likely extending into the April-June quarter. The reasons -- a slow roll-out of a fiscal support package for farmers, and weak transmission of the Reserve Bank's rate cuts."

The government added to that with a decision to immediately inject Rs 70,000 crore ($9.8 billion) to recapitalize state-run banks and encourage them to lend.

The moves were initially cheered by the market, but those gains faded by Thursday as concerns on the slowing local economy and trade talks between the US and China dominated investor sentiment.

"The government has done only some tweaks to existing policies, but nothing that's really big-bang," said NR Bhanumurthy, an economist at Delhi-based National Institute of Public Finance and Policy. "Markets seem to be awaiting more measures. The government shouldn't keep them in waiting."

In the absence of any substantial fiscal stimulus, some economists feel the RBI may have to do more heavy lifting to support growth. Prakash Sakpal, an economist at ING Groep NV in Singapore, expects the central bank to cut the key rate by another 50 basis points before the end of this year.

"Despite all easing this year, there are no improvements in the monetary indicators," he said. "RBI is under pressure from the government for more interest rate and liquidity support for the economy and it will continue cutting policy rates."
