What is intraday liquidity risk and why did regulators start requiring banks to monitor it?

Intraday liquidity risk is the risk that a bank cannot meet its payment and settlement obligations in real time during the business day. It's distinct from overnight liquidity because payment systems process trillions of dollars daily and timing mismatches can cause systemic gridlock.

Why It Matters:

In most Real-Time Gross Settlement (RTGS) systems, each payment must be funded individually. If Haverford Trust (hypothetical) needs to send $2B at 9:00 AM but doesn't receive its expected $1.5B inflow until 2:00 PM, it faces a 5-hour gap. Multiply this across hundreds of banks and you get potential payment gridlock.

BCBS 248 Monitoring Tools:

The Basel Committee requires banks to monitor and report these intraday metrics:

Practical Example — Haverford Trust's Intraday Profile:

At 11:00 AM, Haverford hits its peak negative position of -$2B. This is covered by intraday credit from the central bank (collateralized), but if Haverford couldn't post collateral, it would need to delay payments — potentially causing a cascade.

Risk Management Strategies:

1. Pre-position collateral at the central bank before the trading day opens
2. Stagger outgoing payments — don't send everything at market open
3. Bilateral netting arrangements — reduce gross payment volumes
4. Real-time monitoring dashboards — treasury watches intraday positions continuously
5. Throughput guidelines — commit to sending X% of payments by noon to avoid end-of-day bunching

Exam relevance: FRM Part II may present an intraday liquidity profile and ask you to identify the peak usage, explain how collateral requirements work, or describe the systemic implications of payment delays.
