Nathan Mark Bostock (born October 1960) is a British banker, and was the CEO of Santander UK, until leaving the role in 2022.
[2] Bostock started his career training as an accountant with Coopers & Lybrand before working for Chase Manhattan Bank in risk analysis and interest rate derivatives from 1988 to 1992, rising to head of risk analysis and finance, treasury and interest derivatives (Europe).
[4] In June 2009, Bostock returned to RBS as the "new right-hand man" to CEO Stephen Hester, tasked with trying to sell off non-core assets.
In 2011 he turned down a move to head up the wholesale division of Lloyds Banking Group, reportedly due to the ill-health absence of their chief executive, António Horta Osório.
[4][8] In January 2018, the Liberal Democrat leader Sir Vince Cable stated in Parliament that Bostock had been responsible for RBS's Global Restructuring Group (GRG), when it had "engaged in an intentional strategy that resulted in mistreatment of business customers".
