NEW YORK – JPMorgan is trimming about 4,000 jobs, or about 1.5 percent of its work force, becoming the latest big bank to shrink its staff.

The bank said the cuts will be focused in consumer banking and mortgages. Many of the cuts would come through attrition, but the bank will lay off workers as well, a bank spokeswoman said.

The cuts were revealed in a presentation to investors Tuesday. They are part of the bank's bigger cost-cutting campaign. They come after a year when the bank increased profit and revenue.
