The Financial Conduct Authority has raised Aberdeen Asset Management’s minimum regulatory capital requirement by £140 million to £475 million – triggering fears that other managers will follow suit, with Henderson Group among the next in line.

Aberdeen's shares fell 2.6 % from their close on September 9 to 317p by 12.15 BST following a statement from the asset manager on September 12, dragging other asset management shares down in their wake.
