Get Ready for SOFR and SONIA and ESTR Executive Summary The United States is not the only economy in which is scheduled to be replaced by another benchmark interest rate. As we have discussed in previous reports, LIBOR will be replaced by SOFR as early as the beginning of 2022. The United Kingdom is currently preparing to switch from sterling LIBOR to SONIA (Sterling Overnight Index Average rate), and the will replace LIBOR with €STR (Euro Short-term Rate). In this report, we provide an outlook for these three benchmark interest rates. SOFR Likely to Remain at Low Levels for Quite Some Time As we have discussed in three previous reports this year, LIBOR, which serves as a benchmark The path for interest rate for many businesses and households, is scheduled to be replaced by the Secured SOFR going Overnight Financing Rate (SOFR) as early as the beginning of 2022.1 Although there are a number forward should of technical differences between the two rates, which we discussed in more detail in the earlier generally reports, the two rates generally have a high degree of correlation with the fed funds rate (Figure 1). mirror the Accordingly, the path for SOFR going forward should generally mirror the monetary policy of the monetary policy . of the Federal Reserve.

Although we forecast the unemployment rate will recede further in coming quarters, we do not expect that labor market conditions will have “reached levels consistent with the Committee’s assessments of maximum employment” anytime soon. Furthermore, we do not expect that inflation

will moderately exceed 2% “for some time” as the FOMC is trying to engineer.2 Our expectation that the FOMC will maintain its target range for the fed funds rate at the zero lower bound for a considerable period of time is consistent with the Committee’s own projections. As shown by the “dot plot,” most FOMC members currently project that they will keep rates on hold through 2023 (Figure 2). In sum, SOFR likely will remain near its current rate of roughly 0.10% for the foreseeable future. The Outlook for U.K. Monetary Policy and SONIA Authorities in the United Kingdom have chosen the sterling overnight index average (SONIA) as the preferred LIBOR successor. SONIA, as the name suggests, is an average of interest rates paid on overnight deposits in the wholesale funding market. First published in 1997, SONIA has a relatively long history compared to other new reference rates. This longer track record should facilitate the transition away from LIBOR, as SONIA is well established as a benchmark rate in sterling markets and is already used to value around £30 trillion of assets annually, according to the (BoE). That said, the administration and calculation of the rate has changed over the past few years. The BoE took up administration of the index in 2016, before undertaking a number of reforms in order to improve the robustness of the rate and ensure its compliance with international standards for alternative reference rates. In its current form, SONIA is calculated as a trimmed, volume-weighted average rate based on unsecured overnight transactions greater than or equal to £25 million in value.3 As with SOFR and other new reference rates, SONIA was chosen to avoid some of the pitfalls of its predecessor. The index is based on transactions, rather than a survey, in a liquid market. As part of its reforms, the BoE widened the pool of eligible transactions, resulting in a pool roughly four times larger at the time the changes were being considered (Figure 3). Part of this change was to move beyond the interbank market. Indeed, banks make up a relatively small share of the transactions used in SONIA’s calculation, particularly compared to money market funds and other investment funds.4 Figure 3 Figure 4 Trading Volumes Underlying SONIA United Kingdom Reference Rates Billions of Pounds 80 80 0.8% 0.8% SONIA SONIA: Nov-05 @ 0.05% SONIA: Nov-03 @ £67.2B Reform

Therefore, based on SONIA may incorporate some degree of counter party risk. On the other hand, however, SONIA secured should not reflect fluctuations in the supply and demand of collateral. As we have seen with SOFR, transactions.

the supply and demand of the assets that are used to secure transactions, namely government bonds, can at times have meaningful effects on the behavior of secured money market rates. SONIA tracks quite closely with the BoE’s main policy rate (i.e., the Bank Rate), and SONIA has printed in a very tight range of 0.051% and 0.075% ever since the Monetary Policy Committee (MPC) of the BoE cut the Bank Rate to 0.10% on March 19 (Figure 4). Looking forward, we forecast SONIA tracks that the MPC will maintain the Bank Rate at 0.10% for the foreseeable future. Consequently, SONIA quite closely should remain well-anchored near current levels. The current output gap in the U.K. economy is with the Bank of even larger than it is in the United States, and core inflation was well under control at 1.3% in England’s main September (latest data). Making matters worse, an acceleration in COVID cases has led to policy rate. numerous new restrictions being put back in place on U.K. households and businesses. Beyond COVID, the U.K. economy is also dealing with the continued uncertainty surrounding Brexit and the nation’s future relationship with the European Union. In an effort to provide further monetary support to the economy, the MPC on November 5 increased its asset purchase program by a larger- than-expected £150 billion to a total size of £895 billion. The MPC once again eschewed a negative policy rate, and we do not anticipate the committee taking the Bank Rate into negative territory anytime soon. But, should the MPC eventually cut the Bank Rate below 0%, SONIA could fall into negative territory as well. The and €STR In the euro area, and (Euro Overnight Index Average) have been the dominant reference rates over the past few decades. As in the United States and the United Kingdom, manipulation of surveys and declining volumes in interbank funding markets pushed policymakers Unlike in the U.S in the Eurozone to reform their key benchmark rates, culminating in the EU Benchmarks and the U.K., the Regulation (BMR). Unlike the United States and the United Kingdom, however, the primary inter- primary inter- bank offered rate in the euro area is slated to continue past 2021, as changes have been made to the bank offered methodology of EURIBOR to make it BMR compliant. EONIA, on the other hand, will ultimately rate is slated to be replaced by the euro short term rate (€STR).

The shift from EONIA to €STR mimics the reform of SONIA in the United Kingdom in many ways. Namely, €STR’s methodology includes a much larger pool of transactions that covers not just the interbank market, but larger wholesale funding markets as well. As in the United Kingdom, this expansion aims to improve the robustness of the new by reflecting the actions of a much larger group of players in different funding markets. Also like SONIA, €STR is an unsecured rate in part to match its predecessor. Moreover, the repo market in the Eurozone is more segmented

than its U.S. or U.K. counterparts, due to heterogeneous collateral underpinning transactions in the euro area. €STR sticks to the pattern of a short-term interest rate that closely follows its central bank’s policy We forecast that rate (Figure 6). Unlike the Federal Reserve or the BoE, the ECB, has had a negative policy rate for the ECB will the past few years. In September 2019, the ECB cut its deposit rate from -0.40% to -0.50%, and maintain its €STR has hovered in a tight range between -0.51% to -0.57% subsequently. Like the United discount rate at Kingdom, the Eurozone is dealing with a sharp acceleration in COVID cases, which have threatened 0.50% for the the economic recovery that took hold this summer. But thus far, the ECB has refrained from taking future. interest rates deeper into negative territory, even choosing not to do so during the darkest days of March/April. Therefore, we forecast that the ECB will maintain its deposit rate at -0.50% for the future. Consequently, we look for €STR to remain within a few basis points of its current -0.55% through at least next year, and likely quite longer.
