JPMorgan Chase & Co., the biggest U.S. bank, blocked computer access by its employees to the website of the Financial Times, citing “a potential copyright concern.”

The bank made the move last week, a spokeswoman for JPMorgan said Wednesday in an e-mailed statement. Employees can still access the newspaper’s site through personal devices, provided they respect intellectual property rights according to the bank’s code of conduct, according to the statement. She declined to comment further.

The Financial Times, which competes globally with Bloomberg News and other financial news publishers, was acquired last year by Japan’s Nikkei Inc. for $1.2 billion. Publishers are increasingly limiting access to their websites to paid subscribers to make up for a decline in print revenue. The FT has orchestrated one of the more successful digital transitions, with more than 70 percent of circulation online, according to its website.

A representative for The Financial Times Ltd. declined to comment.

The Times, a London-based newspaper, previously reported the move on Twitter.
