IBOR Transition Digest - August 18, 2023


A new era has begun! Although the key LIBORs now have transitioned to risk-free replacement rates, global transition activity continues with respect to other interbank offered, and similar, rates, and we will continue to update you on these developments.

Invesco Indexing LLC and SOFR Academy, Inc., 31 July 2023
Acknowledging that while neither the USD Across-the-Curve Credit Spread Indexes (AXI) or the USD Financial Conditions Credit Spread Indexes (FXI) were included in the scope of IOSCO’s review, the administrators of AXI and FXI recognize the recommendations made to relevant administrators and intend to continue to provide transparency into how AXI and FXI are constructed, and to develop and maintain all indexes “in compliance with the highest international standards and requirements.”

ARRC July 31 Meeting Readout
Alternative Reference Rates Committee, 31 July 2023
ARRC members characterized the passage of the 30 June 2023 LIBOR transition milestone as smooth and uneventful. The implementation of fallbacks and LIBOR replacements under the LIBOR Act occurred without issue. The LSTA noted the significant uptick in loan fallback amendments in June and highlighted that most leveraged loans and collateralized loan obligations have transitioned to SOFR going forward but will continue to pay LIBOR until their next rate reset date, which generally will be one or three months after LIBOR cessation.

Financial Stability Oversight Council Meeting
U.S. Department of the Treasury, 28 July 2023
The principals reported on the transition away from LIBOR: (a) the transition generally was successful; (b) SOFR is a resilient and sound key benchmark; (c) the recent IOSCO review and related statement was consistent with the ARRC’s conclusion that CD and commercial paper markets are too thin to create a robust interest rate, especially in times of stress; (d) Term SOFR use should remain limited; and (e) all new contracts should include robust fallbacks and follow the ARRC recommendations to avoid repeating LIBOR mistakes. SEC Chair Gensler again called out BSBY specifically as suffering “infirmities that will not stand the test of time,” and stated, with respect to the 15-year LIBOR transition, “we don’t want to do this thing again.” The discussion of LIBOR starts at 28:46.

BSBY Bulletin -- Underlying Volumes, Resiliency in Periods of Stress and Current Landscape
Bloomberg Professional Services, 11 July 2023
Outlines BSBY’s 18-month performance, including during the March 2023 bank failures, and explains volume thresholds—specifically CD and commercial paper volumes, which are a focus of CSR criticism—and the 6-step waterfall if liquidity is challenged, which has not happened to date. BSBY is described as “well positioned to complement the primary and predominant benchmark, SOFR.”

AFX IOSCO Holding Statement
American Financial Exchange, 10 July 2023
Providing “important context and perspective” regarding IOSCO’s 3 July statement criticizing Ameribor’s compliance with IOSCO principles. AFX states that independent risk and accounting firms have found Ameribor compliant with IOSCO principles but it will address specifically the three areas of concern noted by IOSCO in its statement.

With LIBOR’s Long-Awaited Sunset, the Future of Interest Rate Benchmarking Must Be Defined by Choice
American Financial Exchange, 30 June 2023
Arguing, “many US financial institutions are not active in the repo market and do not have large positions in government securities – they can borrow only on an unsecured basis and therefore need a rate that better reflects this segment of the market and funding risk. That means that the industry’s use of SOFR – which is used to determine the interest rates and borrowing costs for approximately 95% of U.S. loans, according to Reuters – does not fully reflect the borrowing costs of the entirety of US capital market participants.”

ARRC June 22 Meeting Readout
Alternative Reference Rates Committee, 22 June 2023
Noting the continued progress in the transition from LIBOR to SOFR, as shown in attached charts. Data from cash and derivatives markets show continued momentum, with SOFR predominant across both cash and derivatives markets. LSTA advised, among other things, that while the majority of LIBOR-linked Collateralized Loan Obligations (CLOs) have not yet reached the 50 percent threshold of underlying loans transitioning away from LIBOR, where the CLO itself would then also become eligible to transition away from LIBOR, most CLO notes have been prepared to transition on or around June 30, according to a major trustee. Additionally, the ARRC recommended that all determining persons, agents, and other parties responsible for disseminating information use the DTCC LIBOR Replacement Index Communication Tool for communicating replacement rates and conforming changes.

LIBOR Countdown!
Loan Syndications & Trading Association, 21 June 2023
Estimating that roughly 65% of outstanding loans have transitioned away from LIBOR, even if a number will continue to pay interest based on LIBOR until the end of the current interest period.

Canadian Alternative Reference Rate Working Group, 27 July 2023
Providing an example of the definitions and provisions that can be included in credit agreements that reference the Canadian Overnight Repo Rate Average (CORRA). Related loan mechanics necessary for a CORRA-based loan to operate are included. Of note is the “Rate Flip” concept, which would allow a borrower to elect to change the CORRA rate option (Term CORRA and Daily Compounded CORRA) during the life of the loan without reopening the credit agreement. The Rate Flip was created in response to an emerging US trend of certain borrowers amending their credit agreement to replace Term SOFR with Daily SOFR as a result of lower hedging costs for Daily SOFR.

CARR releases its recommendations for legacy securities tied to CDOR
Canadian Alternative Reference Rate Working Group, 30 June 2023
CARR’s analysis has found that the exposure and number of tough legacy securities is comparatively small and, given this small size, that the “legislative solutions” seen in other jurisdictions are not necessary for the Canadian market. CARR, however, does recommend adherence to the ISDA protocol for legacy contracts written under ISDA documentation.

The US dollar LIBOR panel has now ceased
Financial Conduct Authority, 3 July 2023
The overnight and 12-month US dollar LIBOR settings have now permanently ceased, and the 1-, 3- and 6-month US dollar LIBOR settings have been designated as Article 23A benchmarks and are being published by LIBOR’s administrator, ICE Benchmark Administration, using a synthetic methodology based on the relevant CME Term SOFR Reference Rate plus the respective ISDA fixed spread adjustment. As with other synthetic LIBOR rates, these settings are now permanently unrepresentative of the underlying markets they previously sought to measure and are intended to cease at end-September 2024, in line with FCA’s April 2023 statement. All new use of synthetic US dollar LIBOR is now prohibited under the Benchmarks Regulation.

Final Transition Approach for SIBOR Loans to SORA
Steering Committee for the SOR & SIBOR Transition to SORA, 30 June 2023
The Steering Committee for SOR & SIBOR Transition to SORA published its response to the March 2023 consultation on SIBOR to SORA loan adjustment spreads, which will allow the industry to complete its transition from SIBOR, ahead of SIBOR’s discontinuation after 31 December 2024.

Adjustment Spreads for the Conversion of SIBOR Loans to SORA - Response to Consultation Feedback and Final Recommendations
Steering Committee for the SOR & SIBOR Transition to SORA, 30 June 2023
Outlining the transition approach for corporate and retail loans. For corporate loans, adjustment spreads based on the 5-year historical median spreads between SIBOR and compounded SORA are recommended. Transition should occur during the time period between 1 September 2023 and 30 June 2024. For retail loans, a two-phase approach is recommended: (a) an active transition phase from 1 September 2023 to 30 April 2023, during which retail SIBOR loans will convert to 3-month compounded-in-advance SORA plus an adjustment spread calculated as the average difference between SIBOR and compounded-in advance SORA over the preceding three-month period (plus the existing margin) and (b) an automatic conversion phase between 1 June 2024 and 30 June 2024, when any retail SIBOR loans not previously converted to SORA will convert to 3-month compounded-in-advance SORA plus an adjustment spread based on the 5-year historical median spreads between SIBOR and compounded SORA.
