If Anthony Gahan had got his way, South Korea’s pension fund might never have landed its £1.2bn deal last summer to buy Goldman Sachs’ shiny new London headquarters. Instead, the building would be among the first landmark listings on Gahan’s new venture, a stock exchange dedicated to trading shares in single properties.

The International Property Securities Exchange received approval from the Financial Conduct Authority in January as the first regulated exchange dedicated to commercial real estate. Now founder Gahan and his colleagues, including Alan Ramsay, chief executive and a former compliance boss at HSBC, are preparing for initial public offerings.
