Post-Libor Transition, There Remain Refinements to Be Made and Risks to Be Aware of

In a report last November, the Alternative Reference Rates Committee declared success as it closed the book on supplanting the Libor benchmark in the U.S. with the Secured Overnight Financing Rate (SOFR). But it did not say that all work is complete.

ARRC’s website remained open though deactivated, as the committee said that its closing report highlighted “key areas that the ARRC believes firms should focus on going forward to preserve the robust system of reference rates achieved through the decade-long transition effort.”

“We must uphold the lessons from the transition to avoid ever needing to repeat it again,” said Federal Reserve Bank of New York president and CEO John C. Williams.

“I urge all market participants to take the closing report’s messages to heart to ensure robust reference rates endure,” said ARRC Chair Peter Phelan, managing director in the Office of the Chief Operating Officer at Citi.

Issues Identified

The ARRC described three areas of focus for firms to “preserve the much more robust system of reference rates that has been achieved”:

  • Maintain an appropriate balance between use of daily SOFR and term SOFR, which provides the term benefit of Libor preferred by corporate issuers. The issue surfaced in fall 2022 when regulators denounced deals attempting to securitize fixed-rate auto loans. They warned that using term SOFR beyond floating-rate business loans could reduce trading in the daily SOFR derivatives used to generate the term benchmark.

The ARRC recommended extending the use of term SOFR to basis swaps that enable swap dealers to reduce the exposure, but it otherwise held firm.

  • Incorporate fallback language to facilitate existing transactions’ transition away from Libor and avoid disruptions, and put fallback provisions in future transactions.
  • Ensure the robustness of reference rates under consideration and that they are fit for purpose. Leading up to the June 30, 2023, cessation date for Libor, the American Financial Exchange’s (AFX’s) Ameribor and the Bloomberg Short-Term Bank Yield Index (BSBY) were competing for market acceptance by incorporating credit-risk sensitivity similar to Libor’s. (SOFR, instead, is a risk-free rate generated from overnight Treasury repurchase agreements.)

In September 2019, executives of 10 large regional banks argued in a letter to banking regulators that standalone SOFR would cause banks’ funding costs to increase during stress periods while the risk-free rate falls, along with their loan revenue.

“The natural consequence of these forces will either be a reduction in the willingness of lenders to provide credit in a SOFR-only environment, particularly during periods of economic stress, and/or an increase in credit pricing through the cycle,” the letter said.

BSBY Bows Out

July 2023 statement by the International Organization of Securities Commissions (IOSCO) questioned the fitness of certain credit-sensitive rates – clearly referring to Ameribor and BSBY – because they are generated from bank-issued commercial paper (CP) and certificates of deposit (CD). Those markets “are not sufficiently deep, robust and reliable to underpin alternatives to USD Libor,” IOSCO said. “Further, gaps in data and volatility related to reliance on a very small number of transactions mean that USD Libor alternatives based on these markets are unlikely to sufficiently implement” IOSCO’s benchmark design principles.

On November 15, Bloomberg announced it would discontinue BSBY in November 2024.

AFX is pushing ahead with Ameribor. After the IOSCO statement, AFX chief executive John Shay told GARP that CP and CD were a “great source” of data to develop a term structure. He stressed that the daily Ameribor, derived from unsecured funding transactions matched over AFX, reflects actual bank funding costs.

“We have discovered hundreds of banks are using our benchmark to write conforming home mortgage loans, warehouse lines of credit, car loans, credit lines, etc.,” Shay said in a more recent interview. “We are thrilled the market has found value in our [credit-sensitive rate] offering.”

Ian Walker, head of legal innovation at Covenant Review, said he has not observed banks using Ameribor or BSBY for large institutional loans.

Lenders in the institutional market typically are collateralized loan obligations (CLOs), insurance companies, family offices, hedge funds and others using third-party capital rather than their balance sheets for funding, Walker explained. Banks, on the other hand, have credit-risk exposure through revolving credit facilities, which tend to be drawn only when the borrower faces a liquidity issue, at which time the cost of funding would equal SOFR.
