Gridlock
Definition:
A situation that can arise in a funds or securities transfer system in which the failure of some transfer instructions to be executed (due to insufficient funds or securities balances) prevents fulfillment of a substantial number of instructions given by other participants
Gridlock resolution
Definition:
Resolution of the gridlock condition without overdrawing the accounts involved.
Details:
Gridlock is a situation that frequently appears in real time systems when the settlement accounts liquidity is extremely volatile. The gridlock resolution algorithm is one of the most important parts of a real time settlement engine.

Note:
This is a series of posts with definitions for the jargon used in #banking, #fintech and #payments.
Too many people use some terms without understanding them beyond the definition.
Too many “experts” use the terms but they never had experience with the actual implementation of anything in #banking, #fintech and #payments.
