NEW YORK ( TheStreet) -- Citigroup ( C) said it is cutting 1,000 jobs in its mortgage business, according to reports by at least three news organizations which cited spokespeople for the bank.

The bank is cutting about 8% of the 13,000 jobs in its mortgage unit, with the bulk of the cuts -- about 760 -- coming from its Las Vegas operations, according to Reuters.

Mortgage revenue is expected to drop sharply in the third quarter as higher interest rates cause refinancing activity to slow.

Other banks are also cutting personnel, including Wells Fargo ( WFC), which has announced 4,800 layoffs so far this quarter, with most of them coming from the mortgage unit. Bank of America ( BAC) has also laid off 2,100 employees, according to several reports.
