Career
Coulbeck was Head of Financial Markets for North America with RBS until June 2001, when he returned to London as Head of Group Treasury. He had been questioned by the Federal Bureau of Investigation in relation to the collapse of Enron, which involved the RBS subsidiary, National Westminster. He is reported to have been the executive who authorised the transfer of assets belonging to Greenwich National Westminster, then a unit of National Westminster bank, to a small company controlled by Andrew Fastow, Chief Financial Officer of Enron, as part of the alleged scam involving the National Westminster Three, although there was no suggestion that he had profited personally from this transaction.
Coulbeck was found dead in a park in Chingford, London on July 11, 2006, having been reported missing by his family the previous week.
Police, who released a photo of Coulbeck, said initially that they were treating his death as "unexplained". The subsequent inquest heard evidence from Coulbeck"s widow, and the eventual verdict was that he committed suicide by slitting his wrists.
Coulbeck was the author of the book The Multinational Banking Industry (), published in 1984.
