He then went to Lincoln College, Oxford, where he obtained a degree in Philosophy, Politics, and Economics and a blue for athletics. After graduating, he qualified as a chartered accountant. He graduated MBA from Harvard Business School in 1975.
After graduating from Harvard Business School, Clementi commenced a career in the finance industry, which culminated in his appointment as Deputy Governor of the Bank of England.
In June 2002, he told the Treasury select committee that a house price crash was a virtual certainty. He said, "I said in April that the level of house price inflation, then running in the mid-teens was unsustainable. Since then we've seen something of an acceleration ... and the longer it goes on, the sharper is likely to be the eventual adjustment.".
In July 2003, he was given the task, by the Secretary of State for Constitutional Affairs, Baron Falconer of Thoroton, of undertaking a wide-ranging independent review of the regulation of legal services in England and Wales, now known generally as the Clementi report.
