SOFR monthly transaction activity — September 2020

October 5, 2020


Each month, our team reviews and discusses the current state of USD LIBOR and SOFR markets, exploring the performance of each index as well as the borrowing and derivatives markets around them.

Since the U.K. Financial Conduct Authority’s 2017 announcement that it would not support LIBOR beyond 2021, market participants have been progressing towards the adoption of replacement indices. This process has moved slowly to date, but with critical deadlines approaching over the next 18 months, U.S. market participants can expect for SOFR-based transactions to become more prevalent.

This update addresses the current state of USD LIBOR and SOFR markets, exploring both performance of the rates and the borrowing and hedging markets that surround them.


  • The spot spread between LIBOR and SOFR for September averaged 6.8 bps and maintained a high level of correlation showing stability between the two indexes in the current environment.
  • The relevant spread in the transition to SOFR (five-year historical median spread between LIBOR and SOFR) has increased by about 0.2 bps on 3-month tenors and stayed relatively flat through September with the divergence on 3-month tenors still attributed to credit market impacts in Q2.
  • SOFR transaction volume increased by nearly 400% quarter-over-quarter, with a disproportionate relative increase in longer-tenor transactions in Q3 2020 (a 700% increase in transactions beyond five years, as compared with a 350% increase in transactions in the 1–5-year range).
  • Longer-tenor SOFR transactions increased significantly in September relative to the total number of transactions and transaction volume, despite both totals decreasing in aggregate compared to previous months.
  • September also saw the first SOFR-based OTC hedge transactions on Agency-originated loans.

Performance of USD LIBOR and SOFR

  • USD LIBOR and SOFR compounded in arrears, the primary backward-looking calculation methodology recommended by ISDA (unless otherwise indicated, all subsequent references to SOFR will mean SOFR compounded in arrears), tend to be highly correlated and directionally aligned.
  • LIBOR and SOFR maintained a consistent relationship throughout September averaging about 7 bps in difference.

  • Transitioning a USD LIBOR-based loan or hedge to a SOFR-based instrument necessitates adjusting the loan/hedge spread to keep the parties economically indifferent.
  • The ARRC Consultation on Spread Adjustment Methodologies for Fallbacks in Cash Products Referencing USD LIBOR recommended a spread adjustment calculated as the median difference between USD LIBOR and SOFR over a five-year lookback period prior to the fallback date.
  • The 3-month tenor still arises from the divergence between 3-month LIBOR and 3-month SOFR from March and April of this year (see Chatham’s market update - May 11, 2020).

  • As of today, LIBOR continues to be the primary index hedged in the market, with SOFR orders of magnitude behind in both transaction volume and count.
  • Some expect transaction volume and count to pick up as Freddie Mac and Fannie Mae continue their transition from LIBOR to SOFR as the index underlying ARMs and SARMs. For more information about this transition, please see Chatham’s FAQ: USD LIBOR Transition to SOFR.

  • In September, Chatham executed the first Agency SOFR-based OTC hedge transaction in the market.
  • The number of transactions is likely to increase as the Agencies now only quote SOFR in their floating-rate term sheets.
  • There was a significant increase in total SOFR transactions from the previous quarter, roughly 400%.
  • Similarly, there was a disproportionate increase in longer-tenor transactions in Q3 2020 with a 350% increase in transactions in the 1–5-year range and a sevenfold increase in transactions above five years.

  • Total SOFR transactions by volume remained relatively consistent from Q2 to Q3 2020, however there was some movement in the proportional breakdown.
  • Longer-tenor transactions (over five years) increased in volume and count by about 700%.
