ICE LIBOR® (also known as LIBOR®) is a widely-used benchmark for short-term interest rates.
The LIBOR methodology is designed to produce an average rate that is representative of the rates at which large, leading internationally active banks with access to the wholesale, unsecured funding market could fund themselves in such market in particular currencies for certain tenors.
LIBOR is currently calculated for five currencies (USD, GBP, EUR, CHF and JPY) and for seven tenors in respect of each currency (Overnight/Spot Next, One Week, One Month, Two Months, Three Months, Six Months and 12 Months). This results in the publication of 35 individual rates (one for each currency and tenor combination) every applicable London business day.
Used globally, LIBOR is often referenced in derivative, bond and loan documentation, and in a range of consumer lending instruments such as mortgages and student loans. It is also used as a gauge of market expectation regarding central bank interest rates, liquidity premiums in the money markets and, during periods of stress, as an indicator of the health of the banking system.
Please also read the sections below on the Future of LIBOR and Information about the UK Government Statement Regarding LIBOR Transition and Intended Legislation.
The ICE LIBOR Output Statement defines LIBOR as:
"A wholesale funding rate anchored in LIBOR panel banks’ unsecured wholesale transactions to the greatest extent possible, with a waterfall to enable a rate to be published in all market circumstances".
Pursuant to the ICE LIBOR Output Statement, LIBOR is currently based on submissions from Contributor Banks that are determined through the use of a standardised, transaction data-driven Waterfall Methodology introduced by IBA. This has been the case since March 2019. Details of IBA’s evolution of LIBOR can be found in the LIBOR documentation section below.
The Waterfall Methodology requires LIBOR Contributor Banks to base their submissions in eligible wholesale, unsecured funding transactions to the extent available:
The Future of LIBOR
In July 2017, the UK Financial Conduct Authority (FCA) announced its intention that it would no longer be necessary to persuade, or compel, banks to submit to LIBOR after December 31, 2021. The FCA and other official sector bodies have made several further statements regarding the need for market participants to prepare to transition from LIBOR to alternative rates by December 31, 2021.
Since July 2017, IBA has engaged with end-users, panel banks, the FCA and other official sector bodies regarding the potential for continuing certain widely-used LIBOR settings after December 31, 2021. This has included surveys of banks and end-users of LIBOR to identify the LIBOR settings that are most widely-used and for which users would like to see IBA work to seek an agreement with globally active banks to support publication after year-end 2021. The focus of this engagement has been on seeking to support transition by providing support for users with outstanding LIBOR-linked contracts that are impossible or impractical to modify before year-end 2021 (so-called “tough legacy” contracts).
IBA has been clear throughout its engagement that any such settings would need to be compliant with relevant regulations and in particular those regarding representativeness. IBA was also clear that, notwithstanding the results of the surveys and IBA’s associated engagement with the banks, there was no guarantee that any LIBOR settings would continue to be published after year-end 2021, and that users of LIBOR should not rely on the continued publication of any LIBOR settings when developing transition or fallback plans.
On December 4, 2020, following discussions with the Financial Conduct Authority (FCA) and other official sector bodies, and in accordance with procedures adopted pursuant to the UK Benchmarks Regulation (BMR), IBA published a consultation on its intention to cease the publication of:
IBA consulted on these intended cessation dates because a majority of LIBOR panel banks had communicated to IBA that they would not be willing to continue contributing to the relevant LIBOR settings after such dates. As a result, IBA considered that it would be unable to publish the relevant LIBOR settings on a representative basis after such dates.
On March 5, 2021, IBA published a feedback statement for the consultation on its intention to cease the publication of LIBOR® settings. IBA received a broad of range of feedback from multiple stakeholders, both on the dates specified above and on the LIBOR transition process generally, including on matters beyond IBA’s remit as administrator of LIBOR.
As announced by IBA on March 5, 2021, in the absence of sufficient panel bank support and without the intervention of the FCA to compel continued panel bank contributions to LIBOR, it is not possible for IBA to publish the relevant LIBOR settings on a representative basis beyond the dates specified above for such settings. As a result of IBA not having access to input data necessary to calculate LIBOR settings on a representative basis beyond the dates specified above for such settings, IBA has to cease the publication of the relevant LIBOR settings on such dates, unless the FCA exercises its proposed new powers (which are included in the current Financial Services Bill as proposed amendments to the UK Benchmarks Regulation - see New FCA Powers to Impose Changes to LIBOR below) to require IBA to continue publishing such LIBOR settings using a changed methodology (also known as a “synthetic” basis).
The FCA has advised IBA that it has no intention of using its proposed new powers to require IBA to continue the publication of any EUR or CHF LIBOR settings, or the Overnight/Spot Next, 1 Week, 2 Month and 12 Month LIBOR settings in any other currency, beyond the above intended cessation dates for such settings. The FCA has also advised IBA that it will consult on using these proposed new powers to require IBA to continue the publication on a “synthetic” basis of the 1 Month, 3 Month and 6 Month GBP and JPY LIBOR settings beyond such dates, and will continue to consider the case for using these proposed powers in respect of the 1 Month, 3 Month and 6 Month USD LIBOR settings.
The FCA has confirmed to IBA, based on undertakings received from the panel banks, that it does not expect that any LIBOR settings will become unrepresentative before the above intended cessation dates for such settings.
Stakeholders who are interested as to statements relating to the cessation or unrepresentativeness of LIBOR for the purpose of contractual triggers for fallback rate arrangements should see the FCA statement issued on March 5, 2021.
On 23 June 2020, the UK Government announced that it intended to legislate to ensure that the FCA has the appropriate regulatory powers to manage and direct any wind-down period prior to eventual LIBOR cessation, in particular to help deal with “tough legacy” contracts. Amendments to the BMR to provide such powers were included in the Financial Services Bill, introduced to Parliament on 20 October 2021.
The new regulatory powers are designed to enable the FCA to designate a critical benchmark, such as LIBOR, and direct a methodology change so that such designated benchmark is published on a “synthetic” basis, in circumstances: (i) where the FCA has found that the benchmark is not representative of the market it seeks to measure or that the representativeness of the benchmark is at risk; (ii) where such representativeness cannot reasonably be restored or there are no good reasons to do this; and (iii) where such action is necessary to protect consumers and/or to ensure market integrity.
The use of such a benchmark by UK supervised entities in regulated contracts would be prohibited, except that the FCA would have the discretion to permit certain legacy use to further its market integrity or consumer protection objectives. The FCA would also have the power to prohibit new use of a critical benchmark where the administrator is to cease providing it.
Recognizing that there are some existing ‘tough legacy’ LIBOR contracts which are particularly difficult to amend ahead of the planned cessation of LIBOR, the FCA is taking steps in relation to its proposed new powers to help reduce disruption in these cases.
Following consultation, the FCA has published statements of policy in relation designating and requiring changes to a critical benchmark. The FCA has also announced its intention to consult in Q2 2021 on its approach to the exercise of its proposed powers to permit certain legacy use of a designated benchmark, and to prohibit the new use of a critical benchmark where the administrator is to cease providing it. As noted above, the FCA will also consult this year in relation to any decision to use its proposed new powers to require IBA to continue the publication of any LIBOR setting on a changed, “synthetic” basis.
The FCA has advised that it will seek stakeholder views on possible methodology changes for LIBOR that are based on the risk free rates chosen as alternatives to LIBOR in the relevant currencies, and on the consensus already established in international and UK markets on a way of calculating an additional fixed credit spread that reflects the expected difference between LIBOR and those risk free rates.
Although the FCA has said that, in directing a methodology change, it will seek to achieve a reasonable and fair approximation of a benchmark’s expected values, it has acknowledged that LIBOR settings published on such a changed, “synthetic” basis will no longer be representative of the underlying market and economic reality that the benchmark is intended to measure.
Calculation & Publication
Each LIBOR® calculation is currently based on input data contributed by a panel of between 11 and 16 Contributor Banks for each of the five LIBOR® currencies. Each Contributor Bank contributes input data for all seven LIBOR tenors in each currency in respect of which it is on a panel.
Each currency panel is composed with reference to the LIBOR Contributor Bank Criteria, which are designed so that the contributed input data is able to produce a rate that is representative of the economic reality.
Each Contributor Bank determines its input data contributions pursuant to the ICE LIBOR Output Statement in order to produce a rate that is anchored in Contributor Banks’ wholesale, unsecured funding transactions to the greatest extent possible, with a waterfall to enable a rate to be published in all market circumstances.
LIBOR is calculated in accordance with the LIBOR Methodology. The published rate in respect of each currency and tenor combination is the arithmetic mean of each Contributor Bank’s contributions in respect of that currency and tenor (after trimming upper and lower values), rounded to five decimal places. Each Contributor Bank's contribution carries an equal weight in the calculation, subject to the trimming.
Details are shown in the table below:
|NUMBER OF CONTRIBUTORS||METHODOLOGY||NUMBER OF CONTRIBUTOR RATES AVERAGED|
|16 Contributors||4 highest and 4 lowest rates||8|
|15 Contributors||4 highest and 4 lowest rates||7|
|14 Contributors||3 highest and 3 lowest rates||8|
|13 Contributors||3 highest and 3 lowest rates||7|
|12 Contributors||3 highest and 3 lowest rates||6|
|11 Contributors||3 highest and 3 lowest rates||5|
If IBA receives fewer than the expected number of submissions in respect of a particular currency, the ICE LIBOR Reduced Submissions Policy will apply to those rates.
LIBOR is normally published for each currency and tenor combination at 11:55 am London time on each applicable London business day.

Governance & Oversight
IBA maintains an oversight committee for LIBOR, which has responsibility for:
The committee has broad market representation, being comprised of Contributor Banks, benchmark users, market infrastructure providers, independent non-executive directors of IBA, and other relevant experts. Representatives from the Board of Governors of the Federal Reserve System, the Swiss National Bank and the Bank of England also sit on the committee as observers.
Oversight Committee Meeting Public Minutes
LIBOR is published on each London business day for all applicable currencies and tenors, except as described below.
There is no LIBOR publication in any currency or tenor if the date is a public holiday in London.
Where a valid publication day is a public holiday in the major financial centre of a currency, there is no publication in the Overnight tenor only, for that currency. All other tenors are published as normal. This rule concerns only the Euro and US Dollar, since Yen and Swiss Franc do not have an Overnight tenor.
The following tables set out the relevant holidays for the different currencies and tenors. Specific dates for each year are available on the Holiday Calendars page. The Holiday Calendars also list the designated Value Dates, by currency and tenor, for each benchmark date.
London Public Holidays
Applies to all LIBOR currencies and tenors;
Euro Public Holidays (Affects Euro Overnight tenor only)
All other relevant Euro public holidays are also London public holidays, so LIBOR is not published on these days.
U.S. Dollar Public Holidays (Affects US Dollar Overnight tenor only)
All other relevant U.S. public holidays are also London public holidays, so LIBOR is not published on these days.
