The debacle that has become known as #HSBCleaks continues to simmer. Stuart Gulliver, chief executive, went public today with a full-page letter in several Sunday papers. The letter offers an apology for the debacle, and it seeks to provide some assurances to both customers and the general public. 
Statements that the bank has "completely overhauled" and "fundamentally changed" its operation sound good, albeit historical. But what of the executives and directors who were not monitoring business operations properly? Are they still happily drawing benefits without further consequence? Does accountability stop short of the executive suite and the boardroom? That Lord Green is the only head to have rolled so far raises more questions than it answers, including what "completely overhauled" actually means.
HSBC and the wider business community must learn from this scandal.
