In April 2007, Hunter was reported in the "Sunday Times Rich List" as the first ever home-grown billionaire in Scotland, with an estimated wealth of £1.05 billion. Due to the financial crisis of 2007–2010 slicing an estimated £250 million from his fortune, Hunter was overtaken as Scotland's richest man in late 2007 by Jim McColl, head of Glasgow engineering firm Clyde Blowers, who has an estimated fortune of £800 million. According to the "Sunday Times Rich List" in 2020, Hunter is now worth £625 million, an increase of £18 million from the previous year.
