Data tracking industrial production and the vital retail sector released Friday showed record declines in April, the first full month of lockdowns to stop the spread of COVID-19 virus that has killed nearly 86,000 people and caused around 36.5 million people to lose their jobs in the world’s largest economy.

With millions of people filing new claims for unemployment benefits every week since the lockdowns began in mid-March, analysts fear the US faces a months-long slog out of the downturn, with no shortage of possible setbacks.

The consumer pullback was “truly staggering,” Oxford Economics said in an analysis of the retail sales data.

“The combination of elevated unemployment, depressed income, frail consumer confidence will continue to weigh on consumer’s appetite for spending.”

Record plunges

Consumer spending has been a crucial part of the US economy, and the Commerce Department reported retail sales sunk by 16.4 percent in April, the largest one-month fall on record.

The decline reversed years of growth and brought the index back to approximately where it was in August 2012.

The hardest-hit businesses were those that relied on shoppers at brick-and-mortar stores, like clothing, which collapsed 78.8 percent, electronics and appliances, which plunged 60.6 percent, and furniture, down 58.7 percent.

Non-store retailers, such as those doing business online, were one of the only bright spots, growing by 8.4 percent.

“Overall this is a dire set of numbers,” said Neil Saunders, managing director of GlobalData Retail. “May will not be a month of celebration. Nor will June. Nor July. Nor probably the rest of this year.”

“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.

On the other end of the supply chain, the Federal Reserve’s industrial production index dropped a record 11.2 percent in April, the largest monthly fall in its 101-year history.
