You are the new CEO of a three-branch community bank with $250 million in assets. Fifty years of real banking history are coming: 20% prime, the thrift crisis, FDICIA, the internet, 2008, zero rates, the 2023 rate shock, the rules that finally let banks touch bitcoin, and the year AI agents ask for access to your ledger. Every decision moves a real balance sheet. Keep capital above the line, keep your depositors' trust, and see what kind of bank you have built by 2030.
