1. Background

Key interbank offered rates (IBORs), types of interest rate benchmarks, are undergoing a period of change as regulators and industry groups have recommended that firms consider adoption of alternative, overnight risk-free rates (RFRs). In the case of LIBOR, the UK Financial Conduct Authority (FCA) has announced that it will not compel or persuade LIBOR panel banks to submit to LIBOR after the end of 2021, calling into question LIBOR’s existence after that date and accelerating efforts to adopt alternative RFRs and fully transition away from LIBOR before it may cease.

This section covers LIBOR in the five currencies in which it is currently published (US dollar, sterling, Swiss franc, Japanese yen and euro), EURIBOR, TIBOR, Euroyen TIBOR, BBSW, HIBOR and CDOR (each an IBOR) and their current administrators, as well as information about the alternative RFR for each IBOR, the administrators for the alternative RFRs, and the designated public-/private-sector working group for each relevant jurisdiction.

ISDA’s Work

ISDA identifies various key ISDA workstreams relating to the reform of IBORs and other interest rate benchmarks and the development of alternative RFRs in this table. ISDA expects to update this document on a quarterly basis.

ISDA conducts its work through a variety of different working groups (WGs): ISDA Americas and Europe Benchmark WG, ISDA APAC Benchmark WG, ISDA JPY Benchmark WG, ISDA EU Benchmark Regulation Advocacy Group and the ISDA IBOR Fallback Implementation Subgroup. To join one of the above WGs:

  • After you create an account, click on the Committees tab and then view My ISDA Committee Dashboard. You can request to join and leave working groups and distribution lists


In 2019, the US CFTC Market Risk Advisory Committee (MRAC) Interest Rate Benchmark Reform Subcommittee recommended ‘plain English’ disclosures for counterparties who continue to transact based on LIBOR and other key IBORs. These disclosures provide helpful background about the potential outcomes for these transactions, including implications for the economics and valuation of the transactions, and are available at CFTC “Plain English” Disclosures for New Derivatives Referencing LIBOR and other IBORs. ISDA maintains a database of supplemental information referenced in these disclosures that provides helpful information for all market participants regarding the IBORs, the alternative RFRs, the administrators for the alternative RFRs and the designated public-/private-sector working group for each relevant jurisdiction.

2. Benchmark Fallbacks/Consultations

*NEW* ISDA Board Statement in Support of IBOR Fallbacks

*NEW* Letter to RFR WGs – ISDA IBOR Fallback Protocol

Recent Educational Materials

To address the risk that one or more IBORs are discontinued while market participants continue to have exposure to that rate, counterparties are encouraged to agree to contractual fallback provisions that would provide for adjusted versions of the RFRs as replacement rates.

ISDA plans to amend certain ‘floating rate options’ in the 2006 ISDA Definitions to include fallbacks that would apply upon the permanent discontinuation of certain key IBORs and upon a ‘non-representative’ determination for LIBOR. ISDA is also amending certain floating rate options that use USD LIBOR as an input to include fallbacks that would apply if USD LIBOR is permanently discontinued. As it has done from time to time, ISDA will amend the 2006 ISDA Definitions by publishing a ‘Supplement’ (or ‘Supplements’) to the 2006 ISDA Definitions. Upon publication of the Supplement for the relevant IBOR, transactions incorporating the 2006 ISDA Definitions that are entered into on or after the date of the Supplement (i.e., the date that the 2006 ISDA Definitions are amended) will include the amended floating rate option (i.e., the floating rate option with the fallback). Transactions entered into prior to the date of the Supplement (so called “legacy derivative contracts”) will continue to be based on the 2006 ISDA Definitions as they existed before they were amended pursuant to the Supplement, and therefore will not include the amended floating rate option with the fallback.

ISDA also expects to publish a protocol (or protocols) to facilitate multilateral amendments to include the amended floating rate options, and therefore the fallbacks, in legacy derivative contracts. By adhering to the protocol, market participants would agree that their legacy derivative contracts with other adherents will include the amended floating rate option for the relevant IBOR and will therefore include the fallback. As always, any such protocol will be completely voluntary and will amend contracts only between two adhering parties (i.e., it will not amend contracts between an adhering party and a non-adhering party or between two non-adhering parties). The fallbacks included in legacy derivative contracts by adherence to the protocol will be exactly the same as the fallbacks included in new transactions that incorporate the 2006 ISDA Definitions.

Target Timing for Fallback Implementation
Submission of final portion of Business Review Letter request to the US DoJ and outreach to other relevant competition authorities Completed (July 2020)
Publication of Bloomberg indicative fallback rates Completed (July 2020)
Publication of amendments to the 2006 ISDA Definitions and related protocol August 2020 (or later date after receive positive Business Review Letter from the US DoJ and similar comfort from other relevant competition law authorities)
Effectiveness of amendments to the 2006 ISDA Definitions and related protocol Late 2020 (or 3-4 months after publication)

Benchmark Fallback Consultations

Due to the fundamental differences in the nature of IBORs and the RFRs, key adjustments are necessary if fallbacks to RFRs are to take effect in contracts that were originally negotiated to reference the IBORs. ISDA ran public consultations to finalize the adjustment methodologies and subsequently issued a tender invitation for a vendor to perform and distribute these necessary adjustments.

At the request of the Financial Stability Board (FSB) Official Sector Steering Group (OSSG), ISDA also consulted on whether fallbacks for LIBOR should be triggered by a pre-cessation ‘non-representativeness’ determination by the UK FCA, as well as cessation.

These consultations ultimately yielded industry consensus, and more information about them can be found below.

The Brattle Group audited the results of the consultations and provided a memo confirming that the adjustments implemented via the Bloomberg Rulebook are consistent with such results.

Please email questions regarding these consultations to

2020 Pre-cessation Fallback Consultation

This consultation sought input on whether to add a pre-cessation trigger to the permanent cessation fallbacks that ISDA is implementing for LIBOR in its standard documentation.


Supplemental Consultation on Spread and Term Adjustments, including Final Parameters thereof, for Fallbacks in Derivatives Referencing EUR LIBOR and EURIBOR, as well as other less widely used IBORs

This consultation sought input on the approach for addressing certain issues associated with adjustments that would apply to €STR if fallbacks in EURIBOR or EUR LIBOR take effect, including the final parameters for these adjustments. It also asks about adjustments that could apply if fallbacks take effect in less widely used IBORs.


September 2019 Consultation on Final Parameters

This consultation sought input on the final parameters related for the adjustments that will apply to alternative RFRs if derivatives fallbacks are triggered.


Supplemental Consultation on Spread and Term Adjustments for Fallbacks in Derivatives Referencing USD LIBOR, CDOR and HIBOR and Certain Aspects of Fallbacks for Derivatives Referencing SOR

This consultation sought input on the approach for addressing certain issues associated with adjustments that will apply to alternative RFRs if fallbacks take effect for USD LIBOR, CDOR or HIBOR. It also asks a question about fallbacks for SOR, which uses USD LIBOR as an input.


Consultation on Pre-cessation Issues for LIBOR and Certain Other IBORs

This consultation related to pre-cessation issues and sought comments on how derivatives contracts should address a regulatory announcement that LIBOR is no longer representative of an underlying market.


2018 Benchmark Fallbacks Consultation

This consultation sought input on the approach for addressing certain technical issues associated with adjustments that will apply to alternative RFRs if the fallbacks are triggered. These adjustments are necessary because of the differences between the interbank offered rates and the RFRs.


3. Bloomberg: Fallback Spread Vendor

In July 2019, ISDA announced that Bloomberg Index Services Limited (BISL) was selected to calculate and publish adjustments related to fallbacks that ISDA intends to implement for certain interest rate benchmarks in its 2006 ISDA Definitions.


Information about other ISDA benchmark reform initiatives is available below:


In anticipation of expected changes in the discount rates used by clearing houses of euro and US dollar, ISDA published Supplement 64 to the 2006 ISDA Definitions on March 30, 2020 to allow parties to specify a discount rate in swaption confirmations for which ‘Cleared Physical Settlement’ or ‘Collateralized Cash Price Cash Settlement Method’ is applicable. At the same time, ISDA updated the ISDA Collateral Cash Price Matrix to align the discount rates specified with expected changes in the discount rates.



On October 1, 2019, EONIA’s administrator, the European Money Market Institute (EMMI), changed EONIA’s methodology to become €STR + 8.5 basis points.  €STR is the Euro Short Term Rate published by the European Central Bank. EMMI also announced that it will cease publication of EONIA after January 3, 2022. Consequently, the Working Group on Euro Risk-Free Rates recommended that market participants pro-actively transition to €STR ahead of EONIA’s cessation and that a fallback to €STR + 8.5 basis points be embedded in contracts that continue to reference EONIA ahead of its cessation.

In response, ISDA published a number of documents:

  • Supplement 59 and Supplement 60 to the 2006 ISDA Definitions provide a new Floating Rate Option (EuroSTR) for €STR and an amended version of the EONIA Floating Rate Options so that they have fallbacks based on the EU Risk Free Rate Working Group’s recommendation.
  • A new set of definitions, the ISDA Collateral Agreement Interest Rate Definitions, provide stand-alone definitions of EONIA and €STR for use in collateral agreements with fallbacks which mirror those in the relevant Floating Rate Options. New versions of this definitional booklet will be published over the coming months which will add definitions of other risk free rates, such as SOFR.
  • A Bilateral Template EONIA Amendment Agreement, which parties can use to amend legacy transactions or existing collateral agreements so that they reference €STR instead of EONIA and/or embed the same fallbacks as provided for in the EONIA and EuroSTR Floating Rate Options and Collateral Agreement Interest Rate Definitions.


EU Benchmarks Regulation and Review

Article 28(2) of the EU Benchmarks Regulation requires supervised users of benchmarks to reflect in their client contractual terms the steps they plan to take if certain contingencies occur in relation to a benchmark (such as its cessation). ISDA published the ISDA 2018 Benchmarks Supplement to provide generic fallbacks for use in relation to benchmarks that do not have their own specific fallbacks. For example, the ISDA IBOR fallbacks described above would apply in precedence to those set out in the Benchmarks Supplement in relation to permanent cessation or any pre-cessation trigger. The ISDA 2018 Benchmarks Supplement is jurisdiction agnostic and so may also be of interest to those looking to improve the robustness of their benchmark-referencing derivatives, for example, in response to IOSCO’s Statement on Matters to Consider in Use of Financial Benchmarks.

On October 11, 2019, the European Commission launched a public consultation on the EU Benchmarks Regulation Review, which included (among other things) questions regarding critical benchmarks, like the IBORs, and third country benchmarks. ISDA submitted a response to the BMR Review on December 31, 2019.
