Dave Hartnett, former head of HMRC, has been appointed alongside several other advisers to help steer a new financial crime committee at HSBC.
He will be joined by Bill Hughes, the ex-Serious Organised Crime Agency chief.
Europe's largest bank, by market, was forced to form the committee by The Financial Services Authority (FSA) after it was hit with a £1.2bn fine in December 2012 as punishment for allowing Mexican drug cartels to launder billions of dollars through its US operations, and helping to fund al-Qaeda and other terrorist groups.
At the time of the probe, Carl Levin, chairman of the Senate's investigations panel, said "the culture at HSBC was pervasively polluted for a long time".
The investigation - which included a review of 1.4m documents and interviews with 75 HSBC officials and bank regulators - found that it had transferred billions of dollars of cash from its affiliate in Mexico to the US, despite warnings that such sums were likely to involve narcotics proceeds. US officials said they believed drug cartels - responsible for a continuing wave of murderous violence across Mexico - laundered illicit funds through the bank's US division between 2002 and 2009.
Following the scandal, HSBC chief executive Stuart Gulliver said he was "profoundly sorry".
But in announcing the new committee yesterday, he said it "will benefit from the experience of the expert advisers, will provide invaluable guidance and advice as we strengthen our capabilities and enforce the highest standards, in particular in relation to combating financial crime."
'The calibre, status and experience of the individuals reinforce once more how seriously we are taking this,' he added.
Other newly appointed members include Nick Fishwick, a former security and counter-terrorism official in the Foreign and Commonwealth Office and Juan Zarate, ex deputy assistant to the US President and deputy national security adviser for combating terrorism from 2005 to 2009. He was responsible for devising and implementing the US government's counter-terrorism strategy.
The committee will meet at least four times a year and report to the board.
The scope of the committee's remit will encompass governance as well as oversight and policy guidance.
