Your Bank of DMZ Cash, shared by all Operators: cash counts only after exfil, and Bank upgrades raise the cap (players report 100K at first).
Your Bank of DMZ Cash, shared by all your Active Duty Operators [1]; cash found in a deployment reaches it only when you exfil. It pays for Gunsmith builds, Vendor items, paid infils (Infil and the Paid Infil system), Lieutenant and Bounty intel, MIA recovery (MIA system) and Operator Prestige (Operator Prestige and permanent Prestige Traits) [1] [2]. Bank upgrades from DMZ levels and the 3D Printer raise how much it can hold [1]; players report a 100K cap at first (unverified).
From the evidence
Players report that the DMZ bank caps at 100K.
