During his career, Thunell has held top leadership positions with several prominent Swedish financial and international businesses. Prior to joining the IFC in 2006, he was CEO of SEB, Sweden’s top corporate bank. He has also served as executive vice president and deputy CEO of Nordbanken and executive vice president of ABB Ltd.
