LONDON (Reuters) - The United States economy will shrink 5.5% in 2020, the steepest drop since 1946, with a huge 38% contraction predicted for the second quarter, Morgan Stanley said on Friday in a new batch of forecasts on the economic damage from the coronavirus outbreak.

The U.S. bank said it had cut its first-quarter forecast to an annualised 3.4% contraction from a previous 2.4%, while in the second quarter the economy is predicted to shrink 38%, up from an earlier forecast of a 30% contraction.

U.S. unemployment will also peak at a record 15.7% in the second quarter - that is up from a previous 12.8% forecast by the bank’s economists - with cumulative job losses of 21 million in the second quarter, Morgan Stanley said.

Projections released by the U.S. Congressional Budget Office showed U.S. gross domestic product will decline by more than 7% in the second quarter as the health crisis intensifies.
