Market benchmark Sensex plunged 894 points on Friday following intensifying rout in global stocks on coronavirus concerns, while the regulatory curbs on Yes Bank further soured sentiment.

After nosediving over 1,459 points during the day, the 30-share index settled 893.99 points or 2.32 per cent lower at 37,576.62.

Likewise, the broader NSE Nifty tanked 279.55 points or 2.48 per cent to close at 10,989.45.

Shares of Yes Bank tanked over 55 per cent after the Reserve Bank of India (RBI) placed the lender under a moratorium, capping deposit withdrawals at Rs 50,000 per account for a month and superseding its board.

The bank will not be able to grant or renew any loan or advance, make any investment, incur any liability or agree to disburse any payment.

The unusual move late Thursday evening came hours after finance ministry sources confirmed that State Bank of India (SBI) was directed to bail out the troubled lender.

Tata Steel was the top laggard in the Sensex pack, cracking over 6 per cent, followed by SBI, IndusInd Bank, HDFC, ICICI Bank and ONGC.

Bajaj Auto, Maruti and Asian Paints were the only gainers.

According to analysts, investors took the Yes Bank episode very negatively, raising questions on the stability of the overall Indian financial system.

Further, domestic stocks faced intense heat as the global markets continued their free fall on the back of coronavirus concerns, they said.

Bourses in Shanghai, Hong Kong, Seoul and Tokyo sank over 2 per cent.

European benchmarks were also trading significantly lower in their morning sessions.

Brent crude oil futures fell 2.54 per cent to USD 48.72 per barrel.

On the currency front, the Indian rupee depreciated 32 paise to 73.24 per US dollar (intra-day).

Asian shares drop as virus fears grip markets again

Asian shares slipped Friday as fears about the virus outbreak once again dominated financial markets.

Japan's benchmark Nikkei dived 3.1% to 20,663.32. Australia's S&P/ASX 200 lost 2.1% to 6,259.20. South Korea's Kospi dropped 2.3% to 2,037.08. Hong Kong's Hang Seng declined 2.1% to 26,213.51, while the Shanghai Composite slumped 0.9% to 3,049.95. Shares also dropped in Taiwan and Southeast Asia.

Markets have endured roller coaster ups and downs for weeks amid uncertainty over how much damage the outbreak of the new coronavirus will do to the global economy.

Vishnu Varathan at Mizuho Bank in Singapore said the potential damage from the new virus was two-fold, with the initial impact coming from a direct impact on the economy.

'One succumbs to the sheer fear of community spread, prospects of deep economic impact from a sharp drop off in demand for travel and seizures in supply-chains,' Varathan said in a commentary.

'The other is a strain that thrives on hopes of stimulus; be it frantic central bank rate cuts, the lull of liquidity infusions or more targeted fiscal offsets to provide pain relief,' he said.

On Wall Street, major indexes lost roughly 3.5%, nearly wiping out the rally from a day before that was fueled by hopes authorities around the world will move to cushion the economic fallout.

These vicious swings are likely to continue, as long as the number of new infections continues to accelerate, many analysts and professional investors say. Thursday was the fourth straight day where the S&P 500 moved at least 2%, the longest such stretch since the summer of 2011.

The growing understanding that the spread of infections — and resulting damage to the economy — may not slow anytime soon is pulling sharply on markets. That pull has taken turns this week with the increasingly worldwide push that governments and central banks are trying to give markets through spending plans and interest-rate cuts.

The yield on the 10-year Treasury note went as low as 0.81% for the first time in history, according to Tradeweb. Tumbling yields have brought the average rate on a 30-year fixed mortgage to a record low of 3.29%.

'It's been a roller-coaster market in recent days for equity investors, and today we appear to be on the downward leg for that ride,' said Terry Sandven, chief equity strategist at U.S. Bank Wealth Management. 'What you need is time, and unfortunately that is still going to result in volatility.'

In China, where the virus outbreak has been steadying, stocks trading in Shanghai have rallied nearly 12% since scraping bottom on Feb. 3. Factories there are gradually reopening, and a return to a sense of normal life may even be on the horizon following swift and severe actions by the government to corral the new form of coronavirus.

But elsewhere in the world, the mood is darker. There are about 17 times as many new infections outside China as in it, according to the World Health Organization.

In the U.S., the death toll climbed to 12 due to the virus. California declared a statewide emergency, Facebook is temporarily closing a Seattle office after a worker was diagnosed with the virus and an industry group said the outbreak could cost airlines as much as $113 billion in lost revenue.

The S&P 500 fell 3.4% to 3,023.94. It's now 10.7% below the record high it set on Feb. 19. The Dow Jones Industrial Average slumped 3.6% to 26,121.28 and the Nasdaq lost 3.1%, to 8,738.60.

Losses were widespread, and energy stocks in the S&P 500 dropped to their lowest level since March 2009, when they were emerging from the financial crisis.

'The Western world is now following some of China's playbook, closing schools and declaring a state of emergency for example, but there is a sense that this is too little, too late,' said Chris Beauchamp, chief market analyst at IG.

Travel-related companies fell again on worries that frightened customers won't want to confine themselves in planes or boats with others. Royal Caribbean Cruises sank 16.3%, Carnival fell 14.1% and American Airlines Group lost 13.4%.

U.S. congressional leaders reached a deal on an $8.3 billion bill to battle the outbreak, which the Senate passed Thursday, and the Bank of Canada followed up on the Federal Reserve's surprise cut to interest rates the day before with its own.

Some economists expect the European Central Bank to take action to support markets before its meeting on March 12.

Benchmark U.S. crude gave up 43 cents to $45.47 in electronic trading on the New York Mercantile Exchange. It lost 88 cents to $45.90 per barrel on Thursday. Brent crude, the international standard, shed 51 cents to $49.48 per barrel.

The dollar fell to 105.77 Japanese yen from 106.13 yen on Thursday. The euro strengthened to $1.1239 from $1.1140.
