William Thomas Winters, CBE (born September 1961) is an American banker who is the chief executive (CEO) of Standard Chartered, and was formerly co-head of JPMorgan Chase's investment bank.

[1] Winters joined the JP Morgan graduate trainee scheme because he was too poor to pursue his interest in international diplomacy.

Winters earned much credit for helping the investment bank avoid "structured products and off-balance sheet vehicles that crippled global markets because they didn't make financial sense", as well as his leadership in the acquisition of ailing rival investment bank Bear Stearns in March 2008.

Standard Chartered's executive pensions attracted some investor criticism in 2019, and some 36% of votes cast at StanChart's annual shareholder meeting in London were against its 2019 directors' remuneration report.

[14] In September 2022, Winters said Hong Kong is "open" and would attend the November 2022 Global Financial Leaders' Investment Summit in the city, despite quarantine measures for inbound travelers.

Winters participated in a charity video entitled "Life's a Pitch" alongside other senior financial managers, which was shown at the Young Vic theatre in London in 2013 and raised £250,000.
