Euribor

Euro Monetary Policy.webp {{legend|#0076BA|Euro Zone inflation year/year}}

]] The Euro Interbank Offered Rate (Euribor) is a daily reference rate, published by the European Money Markets Institute, based on the averaged interest rates at which Eurozone banks borrow unsecured funds from counterparties in the euro wholesale money market (or interbank market). Prior to 2015, the rate was published by the European Banking Federation.

Scope
Euribors are used as a reference rate for euro-denominated forward rate agreements, short-term interest rate futures contracts and interest rate swaps, in very much the same way as LIBORs are commonly used for Sterling and US dollar-denominated instruments. They thus provide the basis for some of the world's most liquid and active interest rate markets.

Domestic reference rates, like Paris' PIBOR, Frankfurt's FIBOR, and Helsinki's Helibor merged into Euribor on EMU day on 1 January 1999.

Euribor should be distinguished from the less commonly used "Euro LIBOR" rates set in London by 16 major banks.

Technical features

 * Official reference: EURIBOR Technical features

A representative panel of banks provide daily quotes of the rate, rounded to two decimal places, that each Panel Bank believes one prime bank is quoting to another prime bank for interbank term deposits within the Euro zone, for maturity ranging from one week to one year. Every Panel Bank is required to directly input its data no later than 11:00 a.m. (CET) on each day that the Trans-European Automated Real-Time Gross-Settlement Express Transfer system (TARGET) is open. At 11:02 a.m. (CET), GRSS (Global Rate Set Systems) will instantaneously publish the reference rate on Refinitiv (ex. Reuters), Bloomberg and a number of other information providers which will then be made available to all their subscribers. The published rate is a rounded, truncated mean of the quoted rates: the highest and lowest 15% of quotes are eliminated, the remainder are averaged and the result is rounded to 3 decimal places. Euribor rates are spot rates, i.e. for a start two working days after measurement day. Like US money-market rates, they are Actual/360, i.e. calculated with an exact daycount over a 360-day year. Euribor was first published on 30 December 1998 for value 4 January 1999.

Euribor futures
EUR Euribor futures are traded on Intercontinental Exchange (ICE) and on Eurex

They were previously also traded on CurveGlobal, part of the London Stock Exchange Group, which has closed down operations in January 2022.

Interest rate swaps
Interest rate swaps based on short Euribors currently trade on the interbank market for maturities up to 50 years. A "five-year Euribor" will be in fact referring to the 5-year swap rate vs 6-month Euribor. "Euribor + x basis points", when talking about a bond, will mean that the bond's cash flows have to be discounted on the swaps' zero-coupon yield curve shifted by x basis points in order to equal the bond's actual market price.

€STR
The other widely used reference rate in the euro-zone is €STR, published by the European Central Bank.
