Bank
Protection from ordinary pocket losses — plus a stock market for the brave.
Cash in hand is exposed: failed robberies take a cut of it, and a surviving killer loots most of it. Banked cash is protected from those ordinary pocket losses — and it earns while it sits.
Deposits & interest
Deposits earn up to 6% over a full season, accruing continuously — park money for half the round and you've earned half the rate. Depositing more doesn't reset what you've already accrued. There are no fees on deposits or withdrawals; move money as the job demands.
Transfers
You can wire money bank-to-bank to any player: minimum $1,000, and the bank keeps a 10% fee — the city's cut for moving money nobody can rob. Every transfer is logged, both directions, with a paper trail you can browse.
The stock market
The bank's trading desk lists five stocks. You get 5 trades per game day, each stock has a limited share supply that refreshes every 4 game days, and no price ever falls below $10.
Prices drift gently upward, wobble day to day, and — this is the part that matters — respond to volume: heavy city-wide buying pushes a price up, heavy selling drags it down. Buy-and-hold roughly tracks bank interest; the real money is in reading what everyone else is about to do.
The board will not read it for you. It shows total volume — how many shares changed hands today — and never the split between buying and selling, nor how much supply is left. A crew that agrees to pile into the same ticker before the day settles knows exactly which way it pushed; everybody else sees only that something happened. Trading on somebody else's move means guessing, and guessing wrong funds their exit.
