It says the change was made because it felt the previous name did not reflect the type of business in which it now operates and says this view was confirmed by stakeholders.
The institute believes the addition of investment more accurately describes the broader nature of its membership, client base and examinations.
The membership of the organisation voted overwhelmingly for the name to be changed at the annual general meeting in September. Designatory letters, such as FSI(Hon) and ASI, remain unchanged.
Chief executive Simon Culhane says: “The institute has evolved since its formation 12 years ago when our exam range was narrow and limited to those working in the Stock Exchange. We now have far greater breadth to our examinations. There are over 15,000 members from across the finance industry in addition to the estimated 35,000 candidates who will take our examinations in over 30 countries, many of whom will be working in the wider investment field.”
