In the 1980's, Citibank's chairman, Walter Wriston, developed a group of five businesses in which he wanted the financial firm to be active. They were:
the individual bank (consumer banking);
the institutional bank (commercial banking);
the investment bank;
insurance; and
information.
How It's Used
“Before the year was out, Wriston’s vision of Citicorp coalesced into what he called his ‘Five I’ strategy, which he unveiled in his March 1984 swan song to analysts. To Citibank’s three existing I’s—the individual bank, the institutional bank, and the investment bank—he now added two more: insurance and information. Wriston expected this Five I’s strategy to become an enduring legacy. But that was not to be.”
