Even at Goldman, some bankers, including David Ryan, considered the bank’s likely profit excessive. Alex Turnbull, a Hong Kong–based Goldman banker whose father, Malcolm Turnbull, would later become Australia’s prime minister, also raised concerns internally. Turnbull wasn’t involved in the deal, but he knew how bond markets worked, and he sent an email to colleagues expressing disbelief about Goldman’s profits. The email led to a reprimand from Goldman’s compliance department, while Turnbull’s boss told him to keep his mouth shut if he ever wanted to get promoted.
