Query your FedNow prefunded balance via your participant interface or sponsor bank API; this balance must be sufficient to fund outbound FedNow payments — unlike Fedwire, FedNow requires prefunding, not end-of-day net settlement
Set up automated balance threshold alerts: when the prefunded balance falls below a configured floor (e.g., 20% of your expected daily volume), trigger a liquidity management transfer (LMT) from your Federal Reserve master account
Initiate an LMT (a same-day transfer from your Fed master account to your FedNow prefunded balance) via the Fed's FedLine or API channel; LMTs post in real time during FedNow operating hours
Monitor inbound FedNow credits throughout the day — these increase your prefunded balance automatically when counterparties send you payments
At end of business, any remaining FedNow prefunded balance can be swept back to your master account via a reverse LMT; automate this to avoid leaving excess idle funds in the prefunded pool
Log all LMT events with timestamps and amounts to build an intraday liquidity dashboard for treasury oversight and regulatory reporting
Known gotchas
FedNow prefunding is a hard requirement — if your balance is zero, outbound payments will be rejected immediately regardless of creditworthiness; sizing your prefund requires forecasting intraday payment patterns
LMTs are not instantaneous from a treasury perspective — there is a processing delay between initiating an LMT and the funds appearing in the prefunded balance; do not wait until the balance is depleted before initiating
FedNow operates 24/7/365 but LMTs from master accounts are only available during Fed operating hours; overnight FedNow activity must be covered by the prefunded balance loaded during business hours
