March's decline in sentiment was the fourth-largest in nearly 50 years, according to Richard Curtin, chief economist for the Surveys of Consumers.

The index of consumer sentiment dropped to 89.1 in March — its lowest level since October 2016 — from 101 in February. Economists polled by Dow Jones expected a fall to 90.

U.S. consumer sentiment fell to a three-year low as the coronavirus outbreak takes a toll on the economy, according to data from the University of Michigan released Friday.

"The extent of additional declines in April will depend on the success in curtailing the spread of the virus and how quickly households receive funds to relieve their financial hardships," Curtin said.

Global coronavirus cases now top 540,000, according to Johns Hopkins University. The U.S. has also overtaken China and Italy as the country with the most cases, with more than 85,000.

The outbreak has led several businesses to close or curb activity. It also sparked a record surge in unemployment claims last week. On Wednesday, the Senate passed a $2 trillion stimulus bill to cushion the economic blow from the coronavirus.

"Mitigating the negative impacts on health and finances may curb rising pessimism, but it will not produce optimism," Curtin said. "There is no silver bullet that could end the pandemic as suddenly as the military victory that ended the Gulf war."
