J.P. Morgan’s latest earnings results show that, in tandem with a $902 million loan loss built in anticipation of losses, a lot remains uncertain. Those loan loss reserves represent a marked change from a year ago, when the company released about $5.2 billion into earnings. Back then, the loan loss reserves that had been built up had been taken against the backdrop of the pandemic. Now the total provision for credit losses stands at $1.4 billion.
