S&P 500 companies lost more than $2 trillion in value in the first few minutes of trading on Monday as investors panicked about the mounting damage from the coronavirus pandemic on the global economy.

Trading on the three main US stock indexes was halted for 15 minutes at the open, the third such pause in six days, as the benchmark index plunged 8% and triggered an automatic cutout.

A sharp cut in interest rates by the Federal Reserve to near-zero only added to the alarm, while traders worried that the pandemic was paralyzing supply chains and squeezing company finances.

Rate-sensitive financial stocks plunged 12.6%, leading declines among the major S&P sectors. Energy stocks tracked a 10% slump in oil prices, while technology stocks also shed 10%.

Apple, Amazon.com and Microsoft Corp together lost nearly $300 billion in market value. Wall Street’s fear gauge jumped 13 points to 70.83.

“The fear factor is going through the roof this morning,” said Peter Cardillo, chief market economist at Spartan Capital Securities in New York.

“Markets are spooked by the emergency of the central banks stepping in and adding billions of dollars of liquidity.”

World stocks plummeted 8%, oil prices slumped 10% and even safe-haven gold took a hit as France and Spain joined Italy in entering a virtual lockdown to contain the fast-spreading disease. Bars, restaurants, theaters and movie houses in New York and Los Angeles were ordered shut.

Underscoring the economic blow of the outbreak, severe virus containment measures sent China’s factory production tumbling at its fastest pace in three decades.

At 10:14am, the Dow Jones Industrial Average was down 2,326.15 points, or 10.03%, at 20,859.47, while the S&P 500 was down 263.50 points, or 9.72%, at 2,447.52. The Nasdaq Composite was down 747.03 points, or 9.49%, at 7,127.84.

Another 1,000-point dip for the Dow will wipe out the entire Trump-bump, taking the index to levels seen before the presidency of Donald Trump.

The S&P 500 retail index fell 9.3% as Nike Inc, Lululemon Athletica Inc and Under Armour Inc said they would close stores in the United States and some other markets.

The S&P 1500 airlines index slumped 16.3% as United Airlines Holdings Inc’s March revenue fell $1.5 billion and the airline warned employees that planes could be flying nearly empty into the summer.

Cruise line operators Carnival Corp and Royal Caribbean Cruises Ltd dropped more than 13%.

Declining issues outnumbered advancers nearly 28-to-1 on the NYSE and 16-to-1 on the Nasdaq.

The S&P index recorded no new 52-week high and 314 new lows, while the Nasdaq recorded two new highs and 1,092 new lows.

US markets should stay open despite intense volatility, the head of the US securities regulator said on Monday, quashing industry speculation that the government might shut down the country’s exchanges to stop a plunge in stock prices.

“Markets should continue to function through times like this,” Securities and Exchange Commission Chair Jay Clayton told CNBC in a phone interview, adding that the SEC was closely monitoring markets and was working with exchanges and market infrastructure providers to ensure they could continue to function.

US stocks plunged on Monday morning on mounting fears the coronavirus pandemic will cause a global recession, again triggering a circuit breaker which temporarily suspends trading.

The turmoil prompted the US Federal Reserve on Sunday to take aggressive action to buttress the economy and financial system, slashing interest rates to near zero, pledging hundreds of billions of dollars in asset purchases and backstopping foreign authorities with the offer of cheap dollar financing.

Some analysts speculated on Monday that closing the markets altogether might be the next step for regulators, which are rapidly running out of tools to arrest the turmoil. Closing the markets is rare but not unprecedented.

The New York Stock Exchange, which is now owned by Intercontinental Exchange, most recently closed on Oct. 29-30, 2012 during Hurricane Sandy and before that on Sept. 11-14, 2011, following the terrorist attacks on the United States, according to its website. It also shut for four months during the outbreak of World War I, the longest closure on record.

The NYSE trading floor remained open on Monday, but the iconic bourse was taking additional precautions, requiring people entering the building to disclose if they had been exposed to the virus and to submit to a temperature check, according to a Reuters reporter present. Those entering the floor were given stamps on their forearm to indicate they’d been checked.
