IBOR Transition

Preparing for the transition from IBOR to risk free rates.

Interbank Offered Rates (IBORs), such as the London Interbank Offered Rate (LIBOR), have been used to set interest rates on a global basis for a wide variety of financial products, including derivatives, loans, bonds and structured products. However, as you may be aware, a number of central banks and international financial authorities have taken the view that these interest rate benchmarks represent a potential systemic risk and therefore need to be replaced or reformed. In particular:

Regulators in a number of key jurisdictions (including the US, the EU and the UK) have a strong preference for IBORs to be replaced by rates based on overnight risk-free rates (RFRs).

Given the short timeline, the differences between IBORs and RFRs, the complexity of transitioning and the variety of products impacted, regulators around the world have been sending clear messages that market participants should prepare for the IBOR transition now.

Societe Generale is fully aware of these challenges and we are actively involved in industry efforts to manage the transition. We focus, in particular, on identifying and addressing the impacts on our clients’ transactions and on our operational capabilities.

As always, Societe Generale is committed to accompanying you throughout this transition period. We will continue to monitor industry developments and will keep you informed on the progresses and conclusions of the industry regarding the IBOR transition process.

"IBOR" stands for InterBank Offered Rates. These interest rate benchmarks reflect the average interest rate of transactions on the unsecured interbank lending market, in different currencies and tenors. They are used to set interest rates on a global basis for a wide variety of financial products, including derivatives, loans, bonds and structured products.

LIBOR (the London interbank offered rate) and EURIBOR (the Euro interbank offered rate) are both examples of commonly used IBORs.

Further to the 2007 financial crisis, in particular, there was a decline in the volume of transactions on the unsecured interbank lending market. These transactions underpin IBOR rates. Due to the disappearance of these transactions, today’s daily publication of IBOR rates relies heavily on "expert judgement" instead. The public sector is concerned that this situation represents a potentially serious source of vulnerability and a systemic risk. Therefore, such IBOR rates need to be replaced or reformed. The UK Financial Conduct Authority (FCA) announced that it would no longer persuade or compel LIBOR panel banks to continue making LIBOR submissions after 2021. Market participants should not rely on LIBOR being available after 1 January 2022.

The public sector, industry bodies and trade associations have identified risk-free rates ("RFRs") as possible replacements for IBORs. These alternative RFRs are at different stages of implementation, depending on their currency.

The table below lists the historical IBOR rates for major currencies and the corresponding alternative RFRs:

The main differences between RFRs and IBORs are the following:

  • Whereas IBORs are forward looking term rates that can apply across multiple tenors: overnight, 1 week, 1 month, 2 months, 3 months, 6 months and 12°months, RFRs are overnight rates with no term element. The only possibility to use RFRs with tenors, as of now, is on a backward looking basis, as averages over a given past period. The methodology recommended by public authorities and working groups to calculate such averages is with compounded interests. 
  • IBORs contain a premium for bank credit risk (and potentially other premiums – liquidity, term and funding) whereas, in general, RFRs contain little or no such additional premiums;
  • Whilst IBORs rely also on expert judgement, RFRs rely exclusively on transactions.

As of now, no forward-looking term rate is available in respect of any of the RFRs. The desire to develop forward-looking RFR term rates has been expressed by a number of industry working groups or private companies. However, so far:

  • GBP: The Bank of England working group is the only one that has indicated that it planned making available forward-looking term rates complementing SONIA, possibly by the end of Q3 2020;
  • USD: The ARRC (the working group with the NY Federal Reserve Bank) is working on a forward-looking SOFR term rate that could perhaps become available by late 2021;
  • JPY: The Bank of Japan’s working group is assessing the possibility to provide a forward looking TONA term rate;
  • CHF: The working group of the Swiss National Bank has made it known that there would be no forward-looking term rate for SARON;
  • EUR: The European Central Bank working group is assessing the possibility to provide a forward looking €STR term rate.
