The Transition from LIBOR

The Transition from LIBOR

As many financial institutions have been finalizing their transition away from the London Interbank Offer Rate (LIBOR), others are still re-configuring models that are impacted by the change. In Part I of this blog, MVRA will touch on the impact of the change and the basic steps financial institutions need to accomplish. In Part II, we will take a more technical view of how our SitusAMC Valuation & Risk Advisory modified its MSR models for the transition.

A Summary of Historical Events

In 2014, the United States Federal Reserve and the New York Federal Reserve Bank established the Alternative Reference Rate Committee (ARRC) to lead the transition away from LIBOR. In June 2017, the ARRC identified SOFR as the recommended alternative reference rate for LIBOR.

Regulatory bodies made it clear in 2020 that entering into new contracts with LIBOR references will create safety and soundness risks. Banks were advised to stop entering into new contracts with USD LIBOR reference rates by December 31, 2021.

One-week and two-month LIBOR has since ceased publication. The ICE Benchmark Administration (IBA), the administrator of LIBOR, announced that the final publication date for other tenors will be June 30, 2023.

The Impact on the ALM Model and Other Models

Financial institutions all over the country have successfully implemented or have started to implement SOFR based pricing in place of traditional LIBOR. Over the prior decades, LIBOR based indexing has dominated the market for floating and adjustable rate instruments. A successful transition to SOFR as the benchmark pricing index is nothing short of a milestone for all financial institutions.

The adoption of SOFR for ALM models and other models is mixed. Institutions that have already adopted SOFR for discounting, new business pricing, and other analyses are ahead of the curve. Many ALM models are capable of SOFR term structure inputs and SOFR modeling, which puts them in line with the current business pricing practices, however, models that do not have SOFR specific inputs need to be challenged for effectiveness, and possibly re-designed.

There are financial institutions that seem to be of the opinion that discounting and new business pricing can be corrected for SOFR pricing by adjusting the discounting or pricing spread, rather than adopting SOFR in their modeling. While they are not wrong, the onus is on the model owner to demonstrate that the correct spread adjustment is made. Clearly, this is not a preferred practice.

For pricing new business, the model owner needs to demonstrate that the correct LIBOR to SOFR spread is used if the pricing curve is USD LIBOR / Swap. However, this is if the model is pricing based on a single tenor point. Different tenor points could have different LIBOR to SOFR spread adjustments.

If discounting is based on the USD LIBOR / Swap curve, the model owner needs to demonstrate that the correct spread adjustments are made across the entire curve, assuming that the intention is to enter SOFR rates into the USD LIBOR / Swap interface. Calculating the correct spread adjustment is complicated by the payment and day count convention between the two rates.

Further complicating this process are global input assumptions that may still bear the LIBOR / Swap naming conventions. The model owner now has the unenviable task of explaining the disconnect between the Institution’s bond and loan pricing practices versus ALM modeling, how spread adjustments are calculated, and why the model isn’t ready for today’s business practices (on the surface, at least).

Apart from ALM models, all models that were (or are) using the LIBOR / Swap curve for cashflow discounting or index forecasting need to be challenged. In a follow-up discussion, MountainView will demonstrate how this can be achieved with a current model setup that does not have a specific section for the SOFR term structure.

What Institutions Need to Do
  1. Talk to Your Model Vendor
    Institutions who haven’t already done so need to inquire into SOFR transition and implementation with their model vendors. At this point in time, there should be no second-guessing on how one can input SOFR rates into the model. Models that do not have a solution for SOFR implementation need to be challenged.
  2. SOFR Indexed Loans in Current Contractual Positions
    Institutions need to be able to observe the newly formed SOFR indexed loans in their current contractual positions. The data Extract-Transform-Load process, data mapping, and other data-related features need to be able to correctly map the SOFR index to the correct SOFR term point defined in the model.
    In addition to this, loans that have contractual features to modify the reference index, and that have been modified, need to be identified and segregated from those that have not. The chart of accounts needs to be able to recognize and identify these loans. Model setup needs to be correctly defined to accommodate SOFR indexed loans for both newly originated loans and loans that have been modified.
  3. Documentation and Change Control
    The impact of the SOFR transition has to be recorded as a matter of change control. Any material impact on interest rate risk and sensitivity, forecasting, and other metrics should be noted, reviewed, and communicated. Documenting the source of the SOFR rates and the timing of the SOFR implementation is the best practice. Creating a corporate memory of this transition is essential as a financial milestone, even if the impact is not significant.
  4. Communication and Socialization
    Communicating to the Board of Directors that the ALM reporting is correctly capturing SOFR is best practice. The ultimate responsibility of model risk rests with the Board. ALCO, internal audit, compliance, regulators, model validators, and all relevant stakeholders need to be informed that IRR reporting now incorporates SOFR indices, pricing, and discounting.
Conclusion

The head-in-the-sand approach to problem solving may not work for this one. We either move forward with the SOFR implementation or risk irrelevant and inaccurate reporting. The movement to this new platform has been slow, many have put it to the side due to lack of resources or other pressing matters. In our next blog we will take a deeper look at our Company’s implementation of SOFR.
