THE DOCUMENT
24 February 2022

NBU Board Resolution No. 18, "On Operation of Banking System Under Martial Law." Issued the day martial law began. In one document it partitioned the domestic payment system: unrestricted cashless transactions alongside capped hryvnia cash, a complete prohibition on foreign currency cash, a fixed exchange rate, and a moratorium on cross-border payments with purpose-based exceptions.
The resolution was amended the same day by Resolution No. 21, then amended more than fifty times through 2023 as restrictions were progressively eased.

Domestic payment channels can continue while cross-border wire transfer routes fail. Where credit card settlement runs through a separate institution on an independent network, it may persist after the wire transfer channel closes. In some cases the central bank intermediates selected transfers through its own remaining correspondent accounts.

A payment outage can hit card authorisation and merchant funding as separate faults, so acceptance at the terminal is restored while the money owed to the merchant arrives a day late under its own incident notice.

A restriction on access to money can be written by purpose as well as by amount, so a balance that cannot be drawn in general becomes payable when it is used for wages, taxes or relief, and the test applied is what the money is for.

Cash withdrawal from foreign currency accounts was prohibited entirely while domestic currency cash remained available under a daily ceiling, so a depositor with balances in both currencies could access one as cash and not the other.
