When participant banks experience intraday liquidity shortages, RTGS platforms use centralized Queue Management Systems to hold non-urgent payments until sufficient reserves become available.
The Central Netting Optimization Framework
  Queue Sorting Type |   Algorithmic Processing Model    |   System Liquidity Performance
---------------------+-----------------------------------+---------------------------------------
  First-In, First-Out | Strict sequential processing      | High vulnerability to queue gridlocks
  Bilateral Netting  | Offsets mutual pending transactions| Resolves local payment blocks quickly

Advanced RTGS engines deploy continuous optimization algorithms that scan pending transaction queues across different banks. When the algorithm identifies a circular web of offsetting payments (e.g., Bank Alpha owes Bank Beta, Bank Beta owes Bank Gamma, and Bank Gamma owes Bank Alpha), it executes a simultaneous multilateral net settlement, clearing the queues instantly without requiring a net injection of new reserves.
