📖 Beginner-Friendly Explanation

STEP 1

Core Concept & Meaning

Central Bank Liquidity Swap Lines are standing bilateral swap facilities between the US Federal Reserve and foreign central banks designed to deliver emergency US dollar funding to global markets during liquidity panics.

The Fed provides fresh USD liquidity directly to partner central banks against foreign currency collateral at benchmark policy rates, anchoring cross-border interbank credit.
