In 1971 Large began his career as an investment banker that lasted for 20 years, first at Orion Bank and then at the Swiss Bank Corporation, where he served on the management board from 1987 to 1989. As such, he got a seat on the London Stock Exchange council during the so-called "Big Bang" of the 1980s as well as a seat on the Takeovers Panel.

Large stopped short of proposing the end of the self-regulation among asset managers that had been established in the 1980s, he suggested more SIB leadership. As SIB Chair, Large started the reforming the SIB; instead of conducting the "Maxwell witch-hunt that ministers demanded", he combined "lighter regulation with stricter disclosure and tougher penalties".
