Banking services comprise deposit, cash management and lending for individual, business and institutional clients.

In Bermuda, the Cayman Islands and Guernsey, Butterfield offers both banking and wealth management.

In 1941, during World War II, the bank opened a branch in St. George's, Bermuda, to serve military personnel.

In 2012, Brendan McDonagh, who was previously chief executive officer of HSBC North America Holdings and group managing director, HSBC Holdings plc, joined Butterfield as a director and executive chairman.

In September 2016, Butterfield became listed on the New York Stock Exchange through a successful $287.5 million initial public offering in the US.

Following the listing, the Carlyle Group divested its holdings of Butterfield shares, and the Bank today is held widely by US institutional investors and individual shareholders.
