WASHINGTON (AP) — U.S. consumer confidence tumbled in March to the lowest level in nearly three years as the impact of the coronavirus began to be felt. The Conference Board reported Tuesday that its confidence index dropped to a reading of 120 in March from February’s 132.6. The steep decline reflected rising worries about the coronavirus during the survey period of March 1-18. Economists say confidence is sure to fall further as the virus’ impact takes a bigger toll on the economy.
