In 2009, Sutherland was a special adviser to the Bank of England’s special Resolution Unit and, last year, was appointed chief executive of Stroud & Swindon Building Society during its merger with Coventry Building Society.
Hector Sants, chief executive of the FSA, said: “John brings to his role considerable experience of the retail banking sector which will be vital in our work in this area.
“Senior advisors are a core part of the FSA’s delivery of intensive supervision. The team provides experience on regulatory, market and consumer matters.”
