U.S. subprime auto lenders are losing money on car loans at the highest rate since the aftermath of the 2008 financial crisis as more borrowers fall behind on payments, according to S&P Global Ratings. Losses for the loans, annualized, were 9.1 percent in January from 8.5 percent in December and 7.9 percent in the first month of last year, S&P data released on Thursday show, based on car loans bundled into bonds.
