He was conspicuous by his wealth and ostentation, and the ambitious and speculative nature of his financial activities. Colebrooke was known as a stockjobber and a Nabob with close ties to Robert Clive and Alexander Fordyce. Colebrooke bankrupted himself through unwise speculations in the crisis of 1772.
