ECB sound practices for managing intraday liquidity risk
A bank can have enough liquidity at the end of the day and still lack the funds to settle a payment at 11:40. The European Central Bank's (ECB) sound practices address this intraday risk.
FNA Intelligent Liquidity Optimisation (ILO) supports all seven ECB principles and helps banks lower the cost of intraday liquidity.

End-of-day balances do not show intraday shortfalls
End-of-day reporting does not show intraday positions, so it misses the shortfalls that stop a payment settling
Live nostro balances alone cannot show upcoming liquidity needs either. The ECB expects banks to combine forecasting, real-time monitoring, payment prioritisation, liquidity sources, stress testing, and governance.
Banks need to understand how client and counterparty behaviour affects payment timing and liquidity needs across currencies and settlement systems. Treasury, risk, and operations teams then need to act on that information together.
Most intraday tools report account balances. ILO models the payments between institutions and accounts. ILO starts from the flows between institutions and accounts, using the network analytics & simulation methods FNA has deployed for central banks since our inception. This supports compliance for attribution (Principle 4), behavioural forecasting (Principle 3), and stress propagation (Principle 7).

Seven ECB principles, seven FNA ILO answers
The ECB’s November 2024 Sound Practices for Managing Intraday Liquidity Risk set out seven principles: risk management, governance, forecasting, real-time monitoring, outflow management, liquidity sources, and stress testing. The ECB separates fundamental practices from examples of good practice. The practices are not formally binding, and the ECB applies them in proportion to each bank.
Principle 1:
Risk Framework
-
ECB expectations: A clear definition of intraday liquidity risk, material drivers identified, limits and early warning indicators, and systems across three lines of defence.
FNA ILO module: Monitor
A consistent measurement layer across account, rail, currency, entity, and counterparty. It gives the evidence base for limits, thresholds, and escalation triggers in line with the bank's risk appetite.
Principle 2:
Governance
-
ECB expectations: A standing forum, senior committee reporting, fast escalation, and BCBS 248 reporting reviewed by the second line.
FNA ILO module: Monitor
Role-specific dashboards on shared definitions, automated escalation triggers, ad hoc reporting during an event, and traceable outputs for committee papers.
Principle 3:
Forecasting
-
ECB expectations: Intraday, end-of-day, and next-day projections that reflect payment priorities and timing, updated through the day.
FNA ILO modules: Monitor + Simulate
Forward views of balances, flows, end-of-day position, and peak intraday usage (largest negative net cumulative position, or LNNCP). Each forecast shows an uncertainty range based on similar days and counterparty behaviour.
Principle 4:
Real Time Monitoring
-
ECB expectations: A live view of flows and available liquidity, with alerts and drill-down to the cause of problems & vulnerabilities.
FNA ILO module: Monitor
One position across settlement systems, correspondents, and infrastructures, in real time. ILO identifies the payments that caused each change in the position.
Principle 5:
Managing outflows
-
ECB expectations: An outflow ladder, a business-as-usual buffer, throttling with a defined lift, and regard for systemic throughput.
FNA ILO module: Optimize
Resequencing solved against the bank's own constraints and back-tested on its settlement history before any change goes live.
Principle 6:
Sources of Liquidity
-
ECB expectations:Reachable liquidity per currency, how quickly it can be mobilised, and whether it remains available under stress.
FNA ILO modules: Monitor + Simulate
Cash, eligible collateral, and credit facilities by currency in one view, with simulation of mobilisation times, transfer restrictions, and availability under stress.
Principle 7:
Stress Testing
-
ECB expectations: Separate business-as-usual and stress buffers per currency, extreme but plausible scenarios, and transfer barriers between entities.
FNA ILO module: Simulate
A configurable digital twin of the bank's payment environment. It tests delayed inflows, margin calls, and reduced funding at account, currency, entity, and counterparty level, separately from production systems.
FNA ILO supports the ECB principles and lowers liquidity costs
ILO helps banks reduce intraday liquidity needs and funding costs, in line with the ECB's sound practices. It combines network analytics, simulation, and payment optimisation, so treasury, risk, and operations teams can find savings and test decisions before they go live.
ILO runs alongside an existing liquidity management solution or replaces it.

-
ILO provides tools and analytical evidence to support all seven principles. Compliance also depends on the bank’s governance, policies, and implementation. FNA’s supervisory intelligence unit works directly with regulators and can support discussions and remediation.
-
LNNCP stands for largest negative net cumulative position: the largest cumulative excess of outgoing over incoming payments during the day. It measures peak intraday liquidity usage. Reducing that usage can create opportunities to lower funding needs or buffers, depending on the bank’s methodology.
-
It changes the order of eligible outgoing payments so incoming funds are reused throughout the day. Critical payments, deadlines, service levels, and limits stay protected.
-
The practices build on BCBS 144 and BCBS 248, which supervisors elsewhere apply too. Banks in the United Kingdom, Canada, and Asia use the same seven headings as a self-assessment structure.
-
No replacement is required. ILO can complement your existing treasury and payment infrastructure, or replace your current intraday liquidity management platform, depending on your requirements.
-
Initial liquidity-saving opportunities can be identified within weeks, subject to data readiness and scope. Deployment timing and realised savings depend on the bank's integration requirements, validation, and approvals.
