Modern financial crises frequently manifest as runs on Wholesale Funding Markets rather than traditional retail deposit runs.

Large banking institutions fund a significant share of their operations by issuing short-term debt instruments (such as commercial paper, repo agreements, and asset-backed commercial paper – ABCP) to institutional investors:

[Institutional Money Market Fund] <--- Injects Short-Term Cash Lines ---> [Special Purpose Investment Vehicle] ---> Purchases Bank Debt Assets ---> [Sovereign Bank Balance Sheet]

Because wholesale funding relies on short-term rollovers (often overnight), the system is highly vulnerable to shifting market sentiment. If institutional investors lose confidence in a bank’s asset quality, they can refuse to roll over its maturing debt lines, cutting off the bank’s funding and triggering a severe liquidity crisis.
