Ralph Adrianus Joseph Gerardus Hamers (born 25 May 1966) is a Dutch businessman who was the chief executive officer (CEO) of UBS Group from September 2020[3] to April 2023.

[9][10] During his time as CEO, he steered the bank to profitability while repaying the Dutch government money it received during the financial crisis.

Also under his leadership, ING invested heavily in its digital transformation, relying far more on its online offering and less on its branch network than most rivals, leading to the bank having one of the lowest cost-to-revenue ratios in Europe at the time.

In December 2020, a Dutch court ordered the public prosecutor to open a probe into Hamers' involvement in his previous role as CEO of ING in the company's failure to comply with anti-money laundering regulations in 2018.

Although the investigation was settled in 2018 with a €775 million fine paid by ING and, according to Bloomberg News, the public prosecutor stated that "it didn’t find enough evidence for criminal accusations against individuals at ING, including the top management",[13] Hamers' investigation could continue into 2022 at the earliest.
