New York CNN Business  — 

America’s retail sales collapsed at a historic rate last month, underscoring just how badly retailers are struggling during the coronavirus crisis.

An advance reading from the Census Bureau showed US retail sales plummeted by 16.4% from the prior month in April, the largest decline since this data series began in 1992. The drop was far worse than economists had expected, and it was significantly steeper than the revised 8.3% sales decline in March.

This April’s retail sales are down 21.6% compared to April 2019. US stocks traded lower following the dire news. The seasonally adjusted total dollar amount spent on goods dropped back to a level not seen since 2013.

As people continue to stay at home across much of the country, they’re spending more on food than before but little on other things. And with mass layoffs leaving millions of Americans out of work, discretionary spending has been crunched.

Excluding autos, the overall drop in retail sales was even steeper at 17.2%. Many Americans are putting big purchases like cars on the backburner.

Particularly weak were sales at clothing and accessories stores, which were down a whopping 78.8% from the prior month and 89.3% year-over-year in April.

“The shutdown of most physical apparel stores, plus the sharp decline in outfits needed for work and leisure, contributed to the precipitous drop,” said Neil Saunders, managing director of GlobalData Retail.

The athleisure and comfort clothing categories were a few lone bright spots last month, Saunders added.

And online sales grew by 8.4% between March and April, as online shopping for essentials continues to boost companies like Amazon.

But retailers have been forced to shutter hundreds of thousands of stores during the crisis. Several have filed for bankruptcy in recent weeks, including Neiman Marcus and J.Crew. JCPenney (JCP)is expected to file for bankruptcy in the coming days.

While April was likely the trough for the retail sector, and May will show some improvements as states are beginning to reopen, it will still be a tough year for the industry, Saunders said.

“Retail’s recovery will be slow and, in our view, it won’t be until 2021 before trade starts to return to more normal patterns,” he said.

The combination of soaring unemployment numbers and frail consumer confidence will weigh on retail and consumer spending in the near term, said economists at Oxford Economics in emailed comments. That’s a major concern, because consumer spending contributes about two-thirds to US GDP growth.

A preliminary look at May consumer sentiment from the University of Michigan showed a slight rebound. The survey-based sentiment index bounced back to 73.7, following a collapse to 71.8 in April. In February, the index stood above 100.

Even so, personal financial expectations for the year ahead weakened further and fell to their lowest level in almost six years, said Richard Curtin, chief economist of the Surveys of Consumers.

Still, some retail chains have bucked the trend for now.

Walmart (WMT), Target (TGT), Kroger (KR)and others are seeing sales increases, as they benefit from Americans buying more groceries and home essentials as they are sheltering in place.

In the long term, analysts expect the crisis to further widen the gap between the industry’s winners and losers.
