Wells Fargo was the first of a slew of banks in announcing Wednesday that it would increase its prime rate to 3.5 percent effective Thursday.

It was the first major bank to announce a change to the base rate for consumer loans, which has been at 3.25 percent since 2008, according to the Federal Reserve's weekly surveys of the 25 largest banks. Wells Fargo was joined in raising the prime rate by other major banks such as Deutsche Bank, Citibank, U.S. Bancorp, JPMorgan Chase, HSBC, KeyCorp, M&T, BMO Harris Bank, SunTrust, Huntington Bancshares and PNC.
