After leaving BZW, Iain continued to focus on financial institutions as co-head of Corporate Finance at Barclays Bank PLC, and latterly as a Managing Director in the Financial Institutions Group at ABN AMRO Corporate Finance.

In 2004, Balcary Associates was hired by ABN AMRO Capital to advise on, negotiate and execute a complex break-up of an investment, which involved a total of 15 divestitures in five countries over a five year period, largely on a full time basis.
