The Senate adjourned on Thursday evening without Republicans and Democrats reaching a deal on the next stimulus package amid the coronavirus pandemic, meaning the extra $600 in unemployment benefits expired after Friday.

And regardless of whether Congress agrees to resume the extra $600 per week or decreases the amount to $200 — as some Republicans propose — experts say that roughly 30 million jobless Americans collecting benefits will not receive any extra stimulus for several weeks.

“It's going to take maybe three to four weeks to ramp it back up again” after any deal, Gbenga Ajilore, a senior economist at the Center for American Progress, a non-profit for public policy research and advocacy, told Yahoo Money.

To simply restart the extra $600 now that they’ve expired would take up to five weeks, according to an estimate by the National Association of State Workforce Agencies (NASWA) provided to Yahoo Money by The Committee on Ways and Means.

“A month is a pretty good bet,” Michele Evermore, senior policy analyst at the National Employment Law Project, told Yahoo Money.

After Congress passes a deal, the Department of Labor would have to issue regulations that states implement. Each step of that process — starting with deadlocked negotiations — will require time.

Meanwhile, the median decrease in unemployment benefits Americans will now see would range from 52% to 72%, according to an analysis by Evercore ISI provided to Yahoo Money.

“Imagine waking up and making half to a quarter of what you made the day before,” said Ernie Tedeschi, a managing director, and policy economist for Evercore ISI previously told Yahoo Money. “It's like a self-inflicted recession.”

The $2.2 trillion CARES Act provided an extra $600 in unemployment benefits that were set to expire at the end of July. The Democrat-controlled House of Representatives passed the $3 trillion HEROES Act, which would have extended extra UI benefits among other stimulus measures, through the end of the year. The Senate never considered the HEROES Act.

By the time Congress actually began negotiating an extension in late July, it was already technically too late. Most states pay those benefits on weeks ending on Saturday or Sunday, so July 25 or July 26 was the last time jobless Americans got the extra $600.

“Republicans just came to the table in the middle to the end of July to start the negotiations,” Ajilore. “The question is what the Republicans and the White House were doing all the month of June and early July.”

‘Outside of a pandemic, we would give them two years to conform’

On July 27, the GOP released a stimulus proposal calling for cutting the extra unemployment benefits to $200 a week through September and then ultimately transitioning to unemployment benefits that replace only 70% of wages.
