Eurodollar

A eurodollar is an unsecured U.S. dollar deposit or bank liability booked at a bank office outside the United States. Some U.S. regulatory and statistical definitions also include dollar deposits booked through an International Banking Facility.

Eurodollars are not euros, physical dollars stored abroad, or foreign-exchange contracts. They are dollar-denominated claims on banks.

Key Takeaways

• The booking office and USD denomination define a eurodollar, not the depositor’s nationality.
• A eurodollar deposit is generally an unsecured claim on the accepting bank.
• The bank must settle in U.S. dollars, but the deposit is not a direct claim on the Federal Reserve.
• Eurodollar deposits can be overnight or term funding and are central to international dollar banking.
• Eurodollar deposit rates are not automatically higher than domestic rates.
• Legacy Eurodollar futures referenced USD LIBOR and were converted or retired during the benchmark transition; they are not the same as deposits.

What Counts as a Eurodollar?

Under the ordinary location test:

The Federal Reserve’s current FR 2420 description describes Eurodollars as dollar-denominated liabilities outside the United States. Detailed reporting instructions determine which offices and transactions enter a specific dataset.

A Deposit Claim, Not a Pile of Dollars

Suppose a corporation places USD 2 million with a bank’s London branch.

The branch records:

• a USD 2 million deposit liability to the corporation; and
• a corresponding asset, such as a claim on another bank, reserves available through a correspondent chain, or a USD loan.

The corporation records a bank deposit asset.

The transaction does not require the same physical dollars to remain in a vault. The bank manages its USD assets, liabilities, liquidity, and payment access so that it can honor withdrawals and transfers.

This distinction matters in stress. The depositor’s claim is on the bank office or legal entity specified by the account agreement, not directly on the U.S. central bank.

The Eurodollar Market

The eurodollar market is the international wholesale market for offshore U.S. dollar deposits, placements, and bank funding. Participants can include:

• global and regional banks;
• corporations;
• investment funds;
• public-sector institutions;
• money-market investors;
• securities dealers; and
• other financial intermediaries.

Transactions can range from overnight deposits to longer-term placements and loans. A bank may obtain dollars through an offshore branch and transfer the funding within its group, subject to legal, liquidity, capital, and operational constraints.

A 2024 New York Fed analysis describes Eurodollars as unsecured dollar deposits booked at bank offices outside the United States and examines their role in bank dollar funding.

Why Eurodollars Exist

The market developed because borrowers, depositors, and banks needed U.S. dollar funding outside the United States. Historical drivers included:

• expansion of dollar-invoiced trade;
• demand for dollar reserves and working capital;
• regulatory and interest-rate differences;
• restrictions that once applied to U.S. domestic banking;
• growth of international banking centers; and
• the dollar’s role in global finance.

Those historical drivers do not mean today’s market sits outside regulation. Offshore branches and subsidiaries can be subject to host-country rules, home-country consolidated supervision, bank resolution regimes, sanctions, anti-money-laundering requirements, capital and liquidity standards, and internal transfer limits.

Eurodollar vs. Domestic Dollar Deposit

Both claims are denominated in USD, but their legal and institutional settings can differ.

Neither category is universally safer or higher yielding. The exact bank, contract, maturity, insurance status, and resolution framework matter.

Eurodollar vs. Foreign-Exchange Position

A eurodollar is classified by the location of a USD bank liability. Currency risk depends on the holder’s economic exposure.

• A USD-functional exporter holding a USD eurodollar deposit may have little direct currency mismatch.
• A CAD-functional investor holding the same deposit has USD/CAD exposure.
• A borrower with USD debt but only local-currency revenue can face a significant currency mismatch.

Booking a deposit offshore neither creates nor eliminates exchange-rate risk by itself.

Worked Example: Dollar Funding

A bank’s London branch accepts a three-month USD 10 million deposit from a corporate treasurer and lends the funds to an importer.

For the depositor:

• the asset is a three-month unsecured USD claim on the bank;
• liquidity depends on withdrawal and early-termination terms;
• return depends on the contractual rate and bank performance;
• insurance must be checked rather than assumed; and
• the relevant currency exposure depends on the depositor’s functional cash flows.

For the bank:

• the deposit is USD funding;
• the loan creates borrower credit risk;
• different deposit and loan maturities can create rollover risk;
• USD payment access and liquid assets must be managed; and
• transferring funds across branches can be legally or operationally constrained.

For the importer:

• USD debt is naturally aligned only if USD cash inflows are sufficiently reliable;
• local-currency depreciation can increase debt-service cost; and
• a lower initial rate may not compensate for currency or refinancing risk.

The eurodollar label identifies the funding market, not the creditworthiness of any participant.

Rates, Benchmarks, and Spreads

A eurodollar deposit rate reflects more than a base benchmark. Relevant terms include:

• fixed or floating rate;
• benchmark and spread;
• observation, reset, and payment dates;
• day-count convention;
• maturity and notice;
• early withdrawal;
• credit and liquidity premium;
• fallback language; and
• fees, tax, and operational costs.

Do not assume LIBOR is the current benchmark merely because older materials associate it with the eurodollar market. New and amended contracts can use SOFR, another permitted benchmark, or a negotiated fixed rate, depending on the product and jurisdiction.

SOFR is a secured overnight rate, while a eurodollar deposit is an unsecured bank claim. A SOFR-linked contract therefore still requires a spread, tenor, and credit analysis appropriate to the actual liability.

What Happened to Eurodollar Futures?

The former CME Eurodollar futures contract referenced three-month USD LIBOR. It was a listed interest-rate derivative, not a contract to deliver an offshore bank deposit.

CME Group reported in April 2023 that most Eurodollar futures and options open interest had been converted to SOFR-based contracts, with the remaining contracts expiring before USD LIBOR cessation.

As a result:

• current short-term U.S. rate futures discussions usually focus on SOFR futures;
• historical price series labeled Eurodollar futures reflect a LIBOR-era instrument; and
• the underlying eurodollar deposit market should not be assumed to have disappeared with the futures contract.

Eurodollar vs. Eurobond

A USD-denominated Eurobond is a tradable debt security issued in an international market. A eurodollar deposit is a bank liability.

The risks and evidence differ:

• deposits require account terms, bank credit, booking office, and insurance analysis;
• bonds require issuer, prospectus, seniority, covenant, price, custody, and market-liquidity analysis.

The fact that both are denominated in USD and associated with offshore finance does not make them the same claim.

Risks and Limitations

• Bank credit risk: eurodollars are generally unsecured claims on banks.
• Resolution risk: branch and subsidiary claims can receive different treatment.
• Deposit-insurance risk: U.S. or home-country protection may not apply.
• Liquidity risk: term deposits may be non-transferable or costly to exit.
• Rollover risk: short-term offshore funding can disappear during stress.
• Transfer risk: law, sanctions, or market disruption can restrict payment routes.
• Benchmark risk: stale LIBOR references or weak fallbacks can affect cash flows.
• Currency risk: a USD claim can be volatile in the holder’s functional currency.
• Operational risk: time zones, cutoffs, correspondents, and internal transfers can delay settlement.
• Label risk: a bond, future, selected deposit, or domestic USD account is treated as the same instrument.

How to Evaluate a Eurodollar Deposit

1. Confirm the USD denomination and booking office.
2. Identify the legal entity or branch that owes the deposit.
3. Determine whether the claim is overnight, demand, term, or negotiable.
4. Review principal, rate, spread, benchmark, day count, and fallback.
5. Check maturity, notice, withdrawal, transfer, and rollover terms.
6. Verify applicable deposit insurance and creditor ranking.
7. Assess bank credit, country, transfer, sanctions, and operational risk.
8. Map the USD payment and correspondent route.
9. Measure currency exposure relative to functional cash flows.
10. Compare the all-in return with equivalent-risk alternatives.

Common Mistakes

• Assuming eurodollars are euros converted into dollars.
• Classifying the deposit from bank ownership instead of booking location.
• Treating a eurodollar as central-bank money.
• Assuming offshore deposits are unregulated.
• Assuming the quoted yield is always above a domestic deposit.
• Treating Eurodollar bonds and deposits as identical.
• Using legacy Eurodollar futures as a current SOFR contract.
• Assuming USD denomination eliminates currency risk.
• Ignoring branch, subsidiary, insurance, and resolution distinctions.
• Comparing rates without matching maturity, credit, liquidity, and withdrawal rights.
