That surge—the result of America's failure to contain the virus—indicates that the U.S. economy is likely to recover more slowly than places that have done a better job, such as the Eurozone. And the longer the pandemic lasts without a vaccine, the longer economic output will remain below pre-crisis levels, leaving permanent scars on many businesses and workers.

"We already know that activity rebounded strongly in May and June, setting the stage for a strong rise in GDP in the third quarter," Andrew Hunter, senior U.S. economist at Capital Economics, said in a note. "Nevertheless, with the more recent resurgence in virus cases starting to weigh on the economy in July, a continued 'V-shaped' recovery is unlikely."

A separate report Thursday showed the number of Americans filing for unemployment benefits increased for a second straight week. Initial claims through regular state programs rose to 1.43 million in the week ended July 25, up 12,000 from the prior week, the Labor Department said. There were 17 million Americans filing for ongoing benefits through those programs in the period ended July 18, up 867,000 from the prior week.

U.S. stocks fell the most in a week after the data releases, and yields on 10-year Treasuries declined.

While the economic restart has helped put 7.5 million Americans back to work in May and June combined, payrolls are down more than 14.5 million from their pre-pandemic peak. The swift deterioration in the economy and job market explain why the Federal Reserve is keeping its benchmark rate pinned near zero and why it rolled out several emergency lending programs geared toward fostering liquid trading conditions in financial markets.

"We have seen some signs in recent weeks that the increase in virus cases, and the renewed measures to control it, are starting to weigh on economic activity," Fed Chairman Jerome Powell said at a news conference Wednesday after the central bank's two-day policy meeting. "On balance, it looks like the data are pointing to a slowing in the pace of the recovery," though it was too soon to say how large—or sustained—this period would be, he said.

With the election only three months away, American voters will have to decide whether to re-elect President Donald Trump to a second term against a backdrop of the virus-induced recession and his response to the health crisis.

Broad-Based Economic Decline

The second-quarter contraction was broad-based, the GDP release showed. Business investment in structures, equipment, and intellectual property slumped at an annualized 27 percent pace, the steepest slide since 1952, while residential investment dropped at a 38.7 percent rate, the most since 1980. More recently, figures have shown a pickup in home sales as Americans take advantage of record-low mortgage rates.

Meanwhile, the pandemic's toll on household spending for services was breathtaking: A 43.5 percent annualized slide during the quarter, subtracting nearly 23 percentage points from GDP. Meanwhile, outlays for goods took away 2.1 percentage points.

After passage in late March of the CARES Act, the largest U.S. stimulus package in modern history, government spending and investment increased an annualized 2.7 percent as non-defense outlays surged at a 39.7 percent pace, the most since the Vietnam War in 1967. However, state and local spending declined at a 5.6 percent pace amid plummeting tax revenues.

The report also showed inventories subtracted nearly 4 percentage points from GDP, while trade added 0.7 percentage point.

The quarterly profile of the economy—as shown by the GDP report—paints a much different picture than monthly data do. As shutdowns gradually lifted and states began to reopen, economic activity stirred back to life in May and June, just not to the levels seen before the pandemic.

Millions of people headed back to work, and Americans ventured out of their homes to spend again at newly reopened stores and restaurants. Bolstered by relief payments and unemployment benefits, retail sales rebounded to near pre-pandemic levels and consumer spending surged by the most on record in May—though still came in short of the February level.

The rebound in activity will largely be captured in the third-quarter figures, which won't be released until Oct. 29, just days before Election Day. But the surge in virus cases has led the economic recovery to stall for several weeks, as consumers hold back on spending and traveling amid continued layoffs, according to the Bloomberg Economics recovery tracker.

Crucial lifelines in the pandemic, like the extra $600 in weekly unemployment benefits, are expiring at a time when the economic recovery is showing signs of teetering. Lawmakers are currently debating another stimulus package to support businesses and the unemployed, but the timing of the bill is unclear. Support from Congress has buoyed the economy in recent months, and further action will be crucial in determining the path of the recovery.

This is the first estimate of three for the second-quarter figures, and the figure will likely be revised over the next two months as the Bureau of Economic Analysis receives further data.
