﻿ J.P. Morgan Chase & Co. is cutting more than 5,000 jobs in an effort to trim costs and become more efficient.

The cuts already have begun, according to people familiar with the decision, and are part of a broader industry move toward Internet and mobile banking. The bank will cut at least 2% of its current workforce in the next year.

The moves come as the nation’s largest bank overhauls its 5,570 branches to rely more on technology and less on human tellers. Chairman and Chief Executive James Dimon said Wednesday that the average J.P. Morgan Chase branch would lose one employee over the next two years, mostly through attrition.

The layoffs are broader, however, affecting all four of the bank’s major business units: corporate and investment banking, consumer and community banking, asset management and commercial banking. Some employees in the “controls” part of the bank, such as those in legal or compliance, also will be affected as the bank trims departments that have grown markedly over the past few years, people familiar with the matter said.

J.P. Morgan hasn’t publicly detailed the layoffs before, but did discuss expense cuts in general in a February presentation to investors. At least 1,000 of the 5,000 layoffs already have been carried out in the past few months, one of the people added.
