The World Bank on Sunday slashed its growth forecast for India's current fiscal year to 6 percent, down from 7.5 percent, warning that the "severe" slowdown could further weaken the country's stuttering financial sector.

In its last forecast in April, the bank had said that India's economic outlook was strong and expected growth of 7.5 percent during the current fiscal year that began in April.

But the country is currently growing at its slowest pace in six years, expanding by just 5 percent in the April-June quarter, hit by flagging consumer demand and a slackening in government spending.

India's industrial output also shrank at itsfastest rate in more than six years in August, data released last week showed,indicating that a slew of government measures had yet to underpin a recovery.

In an effort to kick-start the economy, the Reserve Bank of India or RBI has cut interest rates five times this year and underlined the challenge for policymakers by downgrading its growth forecast to 6.1 percent from 6.9 percent earlier this month.

Last week, ratings agency Moody's Investors Service lowered its growth forecast for India to 5.8 percent for the current fiscal year from 6.2 percent, adding that a long period of weak growth will hamper the government's fiscal consolidation plans.

The World Bank's latest forecast also underlinedsimilar concerns linked to slowing growth and New Delhi's decision to cut thecorporate tax rate, which will cost about 1.5trillion rupees in tax revenues.

"While the authorities have shown steadfast commitment to fiscal prudence, the significant growth deceleration as well as the corporate tax cuts undertaken to counter it come with heightened risks of fiscal slippage," the bank's report said.

The bank said it expects the economy to gradually recover, growing at 6.9 percent in the fiscal 20/21 starting next April.
