In 1999, the
U.S. Senate Permanent Subcommittee on Investigations called Citigroup's chief executive officer,
John Reed, to testify in a public hearing on what the chairman of the Committee, Senator
Carl Levin, called a "rogues gallery" of clients at Citibank's private bank. Reed turned to the new head of the Private Bank,
Shaukat Aziz (later to become the Prime Minister of Pakistan) to take actions to both resolve allegations and ensure against future such events. Aziz in New York called Frank Vogl, then vice chairman of the board of directors of
Transparency International (based in Washington DC), to discuss a joint initiative. They met and Aziz explained it would be more credible if Transparency International, rather than Citi, invited other leading banks to join Citi in exploring efforts to attain voluntary understandings by major banks to full enforce know-your-customer standards. A dinner was then organized in New York at Citi, co-hosted by Aziz and Vogl, was attended by representatives in New York of major banks, as well as then TI chairman
Peter Eigen and then TI-USA board chairman Fritz Heimann. That meeting initiated discussions, led by Aziz and by the then chief risk officer, Hans-Peter Bauer of UBS in Switzerland. A meeting was convened at UBS's training center at Schloss Wolfsberg, near
Ermatingen in Switzerland. The venue provided the name for the group. Work proceeded by representatives of the banks and by Jermyn Brooks, a senior executive at Transparency International, which resulted in the first formulation of the Wolfsberg AML Principles for Private Banking. There were originally eight banks, and except for the US and Switzerland, most countries were represented by their largest private bank. Later "a major US investment bank, a large bank from Japan, and a Spanish bank" joined for the original eleven member-group. On 22 September 2021 the previously loosely associated group of banks founded an association under Swiss law under the name "The Wolfsberg Group" with registered domicile in Basel, Switzerland. In May 2022, in the context of the
2022 Russian invasion of Ukraine the group suggested banks screen their bank customers for negative news stories, in order to assess their financial crime risk.
Dow Jones News Service criticized the document as it did not address the importance of using
licensed media in assessing the credibility of negative news media sources identified on the internet. ==Current members==
