Irish banking stocks, betting giant Flutter Entertainment and Ryanair led Irish shares sharply lower on Monday as European markets tumbled more than 8 per cent as the coronavirus pandemic raged through much of Europe.

The index plunged 8 per cent at the open and trading halted for 15 minutes.

“The market’s in panic mode,” Chris Rupkey, chief financial economist for MUFG Union Bank, said in a phone interview.

“The move overnight was a shock and the market isn’t taking it as the Fed officials riding to the rescue. They’re taking it as ‘get out of the way, look out below, this could be really, really bad’.”

The Fed and other central banks have dramatically stepped up efforts to stabilise capital markets and liquidity, yet the moves have so far failed to boost sentiment or improve the rapidly deteriorating global economic outlook.

An International Monetary Fund pledge to mobilise its $1 trillion lending capacity also had little impact in markets.

“The issue for investors is that the virus’ economic impact is still not known - if this is a one-month event or a one-year event, and how deep the cutback in consumer spending is going to be,” said Rick Meckler, a partner at Cherry Lane Investments in New Vernon, New Jersey.

Central banks in Japan, Australia and New Zealand followed with their own measures, but could not stem a slide in global stocks. S&P 500 futures fell 4.77 per cent to their daily down limit shortly after resuming trading on Sunday night.

The drastic manoeuvres were aimed at cushioning the economic impact as the breakneck spread of the coronavirus all but shut down more countries, though they had only limited success in calming panicky investors.

US president Donald Trump, who has been haranguing the Fed to ease policy, called the move “terrific” and “very good news”.
