Big moves at one of the world's largest banks—HSBC just tapped Brendan Nelson as its next chairman, taking over from Mark Tucker. What's interesting here? They're going back to their old playbook of promoting from within rather than hunting externally. This internal appointment signals a shift back to the bank's traditional governance approach, which some analysts see as a way to maintain institutional continuity during uncertain market conditions. Nelson's ascension comes at a crucial time as global banking faces regulatory pressures and geopolitical headwinds. The move reflects how major financial institutions are rethinking leadership strategies—sometimes the best candidate is already in the building.
