The US economy is facing an accelerating surge in coronavirus cases and harsh new restrictions on business activity without the cushion of meaningful fiscal support, raising fears of a blow to the recovery. Even though equity markets have rallied strongly on advances in the development of a vaccine, the deteriorating health situation across the country is presenting an imminent threat to the US economy as the winter months approach.

The US has already recorded more than 1m new coronavirus cases so far this month, with the healthcare system in parts of the country n.ow under severe strain. Lockdown measures have been introduced in a number of states and major cities in an attempt to contain the spread.

Whereas the White House and Congress agreed to $3tn in government spending measures to counter the initial pandemic lockdowns in March and April, they failed to reach a deal on further stimulus before the election and have made little if any progress towards an agreement since the vote.

Joe Biden, the US president-elect, has called for a compromise even before he takes office in January given the urgency of the situation, a position that was reinforced on Sunday by Ron Klain, his pick for White House chief of staff.

“There’s a lot of things that are going to have to wait until Joe Biden is president, but this is not one of them,” he told NBC on Sunday, adding that direct help to people and state andlocal governments to prevent job losses was crucial. “This is a national crisis, it needs bipartisan action now.” Even Donald Trump, the outgoing president who has waxed and waned over the issue of new coronavirus economic relief for months, said in a tweet over the weekend that he wanted an agreement.

Still, big differences remain between congressional Democrats who are pushing for a broader and more costly package worth more than $2tn, and Republican lawmakers who think the economy needs far less. This has economists worried that no significant agreement will be reached, leaving households and businesses to fend for themselves even as new lockdowns are introduced and workers are furloughed or dismissed.
