The tools and resources applied by a bank in managing intraday liquidity risks must be tailored to the bank's business model and role in the financial system. This relates to, for example, whether the bank participates in a payment or settlement system directly or through correspondent or custodian banks, and whether it provides correspondent or custodian services and intraday credit facilities to other banks, firms or systems. If a bank relies heavily on secured funding markets, the bank must have adequate systems and procedures in place to monitor positions in securities settlement systems.
