What Is It?
A liquidity crisis occurs when financial institutions or markets cannot obtain sufficient cash or easily convert assets to cash. Unlike insolvency (negative net worth), liquidity crises are about cash flow timing—but can cause insolvency if asset sales destroy value.
Origin
Historical liquidity crises include 1907 Panic, 1929 Crash, 1998 LTCM, 2008 Global Financial Crisis, and 2020 COVID crash. Each demonstrated how funding freezes can transform solvency issues into systemic crises. Central banks as lenders of last resort emerged from these experiences.
Why It Matters
Liquidity crises cause fire sales, contagion, and systemic collapse. Understanding liquidity risk—funding liquidity and market liquidity—is essential for financial stability. Modern risk management emphasizes liquidity stress testing and buffers.

Market Mechanics
Funding liquidity is the ability to borrow cash. Market liquidity is the ability to sell assets without large price impact. The two interact—when funding dries up, forced asset sales impair market liquidity. Haircuts on collateral rise in stress, amplifying liquidity needs.
How It Behaves
Liquidity is procyclical—abundant in good times, evaporating in stress. Flight-to-quality concentrates liquidity in safe assets. Interbank markets freeze as trust breaks down. Asset prices disconnect from fundamentals. Central bank intervention restores liquidity through lender of last resort functions.

Institutional Behavior
Banks manage liquidity coverage ratios (LCR) and net stable funding ratios (NSFR). Asset-liability management matches durations. Central banks provide liquidity through discount window, repos, and QE. Money market funds are key funding sources but prone to runs.
