BCBS 248 Intraday Liquidity Monitoring Snapshot

BCBS 248 "Monitoring tools for intraday liquidity management" (Basel Committee on Banking Supervision, April 2013): enter a time-stamped list of settlement transactions and the kernel walks a cumulative net position to find the day's largest negative excursion — the daily maximum intraday liquidity usage. Alongside it: start-of-day available liquidity (your input, echoed), total gross payments and receipts, whether time-specific obligations settled by their due time, and whether your available intraday liquidity sources cover the day's peak usage. Deterministic classification only — not a filing, not a supervisory submission, and not a claim of full BCBS 248 seven-tool coverage.
