The Eurodollar market historically served as the basis for the LIBOR rate, the world's most widely referenced floating interest rate benchmark, and remains a critical mechanism for offshore U.S. dollar funding.", "key_takeaways": [ "Eurodollar deposits carry no Federal Reserve reserve requirement, allowing offshore banks to offer slightly higher deposit rates than domestic U.S. banks.", "The Eurodollar futures contract (traded on the CME) was the world's most liquid futures contract prior to its discontinuation after LIBOR cessation in 2023.", "Eurodollar rates historically reflected the interbank lending rate for 3-month USD deposits among AA-rated banks—forming the basis for LIBOR.", "The Eurodollar market originated in the 1950s–1960s when Soviet-bloc countries held dollar reserves at European banks to avoid U.S. jurisdiction.", "SOFR has replaced LIBOR as the dominant reference rate for USD interest rate derivatives, reducing but not eliminating Eurodollar market significance." ], "detailed_explanation": "The Eurodollar market's origins lie in Cold War geopolitics. In the 1950s, the Soviet Union and Eastern European nations held U.S. dollar reserves but feared seizure by U.S. authorities given Cold War tensions. By depositing dollars at European banks—particularly in London—these reserves remained in U.S. dollars but outside U.S. jurisdictional control. European banks, notably the Banque Commerciale pour l'Europe du Nord in Paris (nicknamed 'Eurobank'), accepted these deposits and on-lent them, creating the first Eurodollar market. The 'euro' prefix refers to European origin, not the European single currency.\n\nThe Eurodollar market grew explosively through the 1960s–1980s for structural reasons. U.S. Regulation Q capped interest rates on domestic bank deposits, creating a significant yield advantage for Eurodollar deposits that faced no such cap. Petrodollar recycling after the 1973 oil shock—as OPEC countries accumulated vast dollar surpluses and deposited them in London and other financial centers—further deepened the market. The absence of reserve requirements on Eurodollar deposits allowed banks to offer marginally higher rates, attracting global dollar savings.\n\nThe LIBOR connection made Eurodollar rates systemically important. LIBOR (London Interbank Offered Rate) was intended to measure the rate at which prime banks could borrow from each other in the interbank market—effectively the Eurodollar deposit market. As LIBOR became embedded in hundreds of trillions of dollars of floating-rate loans, mortgages, student loans, and derivatives, the Eurodollar market's pricing became the reference for a substantial fraction of global financial contracts. The LIBOR rigging scandal (2012), where traders at major banks manipulated LIBOR submissions for profit, exposed the vulnerability of benchmark rates and catalyzed the transition to SOFR.\n\nEurodollar futures—traded on the CME Group's Chicago Mercantile Exchange—were for many years the world's most liquid futures market by open interest, serving as the primary tool for hedging and speculating on short-term U.S. interest rates. Each contract represented $1 million of face value of a 3-month Eurodollar deposit, priced as 100 minus the expected 3-month LIBOR rate at expiry. A strip of Eurodollar futures provided a market-implied path for future short-term rates—essentially the forward curve for USD rates up to 10 years out. The final Eurodollar futures expired in December 2024 as LIBOR ceased, with the CME's SOFR futures taking their functional place.\n\nThe offshore Eurodollar market continues to function as the mechanism through which global banks fund their dollar-denominated balance sheets. The Federal Reserve's swap lines with foreign central banks—activated during the 2008, 2020, and other crises—exist precisely to provide emergency Eurodollar liquidity when private markets seize up, demonstrating the systemic importance of the offshore dollar funding market.", "example": "A Japanese bank needs to fund a $500 million U.S. dollar loan to a multinational corporation. Rather than sourcing U.S. deposits (costly and operationally complex), it raises $500 million through 3-month Eurodollar deposits in the London interbank market at SOFR + 0.25% per annum. Using the formula: Interest = $500M × (SOFR + 0.25%) × (90/360), with SOFR at 5.3%, the 3-month funding cost is $500M × 5.55% × 0.25 = $6.9375 million. The bank rolls this deposit every 90 days, bearing rollover risk that rates or credit conditions may change. To hedge this floating-rate risk, the bank enters a 3-year SOFR interest rate swap, paying fixed and receiving floating, converting its variable funding cost to a fixed obligation.", "formula": "Eurodollar Futures Price = 100 - Expected 3-Month Rate; Implied Rate = 100 - Futures Price", "formula_latex": null, "interactive_type": "chart", "calculator_id": null, "related_terms": [ "basis", "cap", "collateralized-mortgage-obligation", "effective-duration", "exchange", "face-value", "hedging", "interest-rate", "interest-rate-swap", "libor", "liquidity", "open-interest", "swap", "swap-spread", "yield" ], "backlinks": [ "back-months", "commodity-pool", "convexity-adjustment", "cross-margining", "day-count-convention", "dominant-future", "electronic-trading", "exchange-for-physicals", "final-settlement-price", "floor-trader", "jensens-inequality", "last-notice-day", "lookalike-contract", "matching-algorithm", "modified-duration", "paycollect", "strip-options", "ted-spread", "trend-following" ], "cross_references": [ "basis", "cap", "exchange", "face-value", "hedging", "interest-rate", "interest-rate-swap", "libor", "liquidity", "open-interest", "swap", "yield" ], "tags": [ "level:intermediate", "cat:fixed-income" ], "asset_classes": [ "fixed-income" ], "regulators": [], "see_also": [], "sources": [], "wordcount": 760, "checksum": "53a26d0833b408e8", "version": "2026.05.03", "license": "CC-BY-4.0", "updated_at": "2026-09-07T02:15:24+00:00", "_links": { "self": "https://hedgefund.wiki/api/v1/terms/eurodollar", "jsonld": "https://hedgefund.wiki/api/v1/terms/eurodollar?format=jsonld", "markdown": "https://hedgefund.wiki/api/v1/terms/eurodollar?format=md", "graph": "https://hedgefund.wiki/api/v1/graph/eurodollar", "category": "https://hedgefund.wiki/api/v1/categories/fixed-income", "schema": "https://hedgefund.wiki/schema/term.schema.json", "html": "https://hedgefund.wiki/#/terms/eurodollar" } }
