The Global Dollar Liquidity Cycle & Eurodollar System
How the offshore Eurodollar market, cross-currency basis swap spreads, and Fed central bank swap lines drive global liquidity.
1. The Offshore Eurodollar System
The Global Dollar Liquidity Cycle is the lifeblood of international commerce. Over 80% of global trade financing, 60% of foreign exchange reserves, and the vast majority of cross-border interbank liabilities are denominated in U.S. dollars through the offshore Eurodollar banking system.
2. Cross-Currency Basis Swaps & Funding Strains
When foreign financial institutions face a shortage of U.S. dollar funding, they turn to the Cross-Currency Basis Swap market. A negative cross-currency basis (e.g. EUR/USD or JPY/USD basis widening negative) signals that non-U.S. banks are paying an extreme premium to borrow dollars.
3. Federal Reserve Central Bank Liquidity Swap Lines
To prevent offshore dollar funding crises from transmitting back into domestic U.S. financial markets, the Federal Reserve operates standing Central Bank Liquidity Swap Lines with five major central banks (ECB, BOJ, BOE, SNB, BOC). These facilities allow foreign central banks to provide liquidity in U.S. dollars to their domestic commercial banks.
