March 23 (Reuters) - Wall Street's slide deepened on Monday as the rapidly spreading coronavirus forced more U.S. states into lockdown, eclipsing optimism from an aggressive policy easing by the Federal Reserve and putting the S&P 500 on pace for its worst month since World War Two.
After cutting interest rates to near zero and offering to buy more Treasury bonds and mortgage-backed securities, the Fed will now lend against student loans and credit card loans, as well as back the purchase of corporate bonds and direct loans to companies.
The extraordinary moves briefly lifted U.S. stock index futures more than 3%, but the mounting death toll from COVID-19 and growing evidence of the economic damage to Corporate America quickly sent the main indexes back into the red.
"It's their bazooka moment, which should be a sign to investors that the Fed will provide any and all liquidity necessary to support the economy through this period," said Russell Price, chief economist at Ameriprise Financial Service in, Troy, Michigan.
"But quite frankly, the market is just in a waiting period right now until the virus runs its course and some of the therapies and other treatments are able to improve outcomes."
Investors had hoped the U.S. Senate would clear a $1 trillion-plus coronavirus stimulus package over the weekend, but Democrats and Republicans were still scrambling to come to an agreement.
Ohio, Louisiana and Delaware have now joined New York and California in asking people to stay home, foreshadowing a near halt in economic activity and more pain for U.S. equities, which have already lost more than $9 trillion in value since a record high hit last month.
Goldman Sachs expects an outright contraction in global real GDP in 2020 on the back of a 24% plunge in U.S. real GDP in the second quarter: two-and-a-half times as large as the previous post-war record.
