Chip Kruger, Chief executive, Natwest Markets

To say that Chip Kruger is not well known in London is an understatement. Few UK bank analysts have met him or know much about him except that he used to co-run Greenwich Capital Markets, a successful bond-trading business in Connecticut, that was acquired by NatWest.

Kruger’s low profile is partly explicable by his reticence with the press. Greenwich employees are renowned for being tight-lipped, and Kruger – who is especially protective of his privacy – has so far declined all interview requests since taking over at NatWest Markets in August.
