A two-week shutdown of the U.K. hospitality sector could knock at least 2% off the nation’s gross domestic product and trigger further stimulus from the Treasury and Bank of England, according to JPMorgan Chase.

Mounting virus cases in Britain have led to speculation the government will impose at least a partial lockdown as soon as next month.

The fear among economists is that such a move would choke off the nation’s recovery from its record contraction in the second quarter -- which has thus far been largely driven by a pickup in consumer spending.

In addition to the knock to monthly GDP, closing the hospitality industry for two weeks could trigger behavioral change that would mean “the indirect impact might end up being larger,” JPMorgan economist Allan Monks wrote in a note Monday.

Any lockdown would probably trigger a “a greater policy response” from both the BOE, in the form of an earlier and larger increase in bond purchases, and the government, via bringing forward the Budget and “offering further support for affected workers,” he said.

The central bank’s current projections, which see output reaching pre-crisis levels next year, are based on an easing of virus uncertainty and avoiding a nationwide lockdown.

Prime Minister Boris Johnson will convene crisis talks on tackling the resurgent coronavirus on Monday. His top scientific adviser warned the U.K. is on course for 50,000 new cases a day by mid-October without urgent action.

Still, officials are also concerned about the longer-term economic impact of more restrictions -- a trade off England’s chief medical officer Chris Whitty acknowledged on Monday.

“If we do too little, this virus will go out of control and you will get significant numbers of increased direct and indirect deaths,” he said. “But if we go too far the other way, then we can cause damage to the economy which can feed through to unemployment, to poverty, to deprivation -- all of which have long-term health effects.”
