Household net worth soared to a record high in the first quarter, Federal Reserve data show, and the financial-obligations ratio relating consumer debt to income matched the lowest in 33 years, Bloomberg News reported yesterday. Consumer loans are rising, and the American Bankers Association reports the share of delinquencies on bank cards is the smallest since 1990. Credit is thawing gradually for residential mortgages, one reason new-home purchases in June reached the highest since 2008. Lenders also are easing standards for auto loans to expand the pool of buyers and drum up more business. That has put car sales on track for the best pace since 2007, helping companies including General Motors Co., Ford Motor Co. and parts maker Lear Corp. to report better-than-estimated earnings.
