Bloomberg Begins Publishing Calculations Related to IBOR Fallbacks

Bloomberg and ISDA today announced that Bloomberg Index Services Limited (BISL) has begun calculating and publishing fallbacks that ISDA intends to implement for certain key interbank offered rates (IBORs).

ISDA will soon publish amendments to its standard interest rate derivatives definitions to incorporate these new fallbacks, which are adjusted versions of various risk-free rates (RFRs). RFRs, which are overnight rates without a credit component, are inherently different from IBORs, which have term structures and credit sensitive elements. Accordingly, ISDA is implementing adjusted versions of the RFRs to serve as IBOR fallbacks based on feedback received from several market consultations regarding these differences.  In July 2019, ISDA announced that Bloomberg had been selected to calculate and publish these adjusted RFRs as fallbacks following an in-depth selection process. The contractual changes to embed the fallbacks are due to take effect in ISDA’s derivatives documentation at the end of the year.

Calculations published by BISL include the adjusted RFR (compounded in arrears), the spread adjustment and the ‘all in’ IBOR fallback rates for the following IBORs across various tenors: the Australian dollar Bank Bill Swap Rate (BBSW), the Canadian Dollar Offered Rate (CDOR), Swiss franc LIBOR, EURIBOR, euro LIBOR, sterling LIBOR, HIBOR, euroyen TIBOR, yen LIBOR, TIBOR and US dollar LIBOR.

“The introduction of robust new fallbacks for derivatives contracts will significantly reduce the systemic risk posed by a permanent cessation of a key IBOR. Publishing indicative spread adjustments and all-in fallback rates now will help firms as they prepare to implement the new fallback methodology,” said Scott O’Malia, ISDA’s Chief Executive.

“We are pleased to partner with ISDA to support the markets through the calculation and distribution of IBOR fallbacks. This is an important move forward as we continue to help our clients with their IBOR transition efforts,” said Umesh Gajria, Global Head of Index Linked Products at Bloomberg. “Our role as fallback adjustment provider enables us to deliver an important service, supported by our broad distribution channels and the strength of Bloomberg’s index business as we remain focused on bringing transparency to the markets.”

Bloomberg will make the adjusted RFRs, spread adjustments and all-in fallback rates broadly available to industry participants through various distribution channels, including the Bloomberg Terminal®, where the data will be displayed on FBAK <GO>, and other Bloomberg solutions including the desktop API and Bloomberg Data License. The real time data will also become available through authorized redistributors, and is publicly available on the Bloomberg website on a delayed basis.

While the fallbacks are not separate benchmarks from the RFRs for regulatory purposes, the calculations are being performed by BISL, which is authorized by the Financial Conduct Authority as a regulated UK benchmark administrator under the European Union Benchmarks Regulation. BISL has conducted index administration since 2014, including serving as the administrator of the Bloomberg Barclays fixed income indices.

Additional information about the methodology and implementation of IBOR fallback rate calculations can be found on the ISDA website and on ISDA <GO> via the Bloomberg Terminal.

A fact sheet on the new fallbacks is available here.
