EURIBOR The new EURIBOR gets through a challenging 2020 In the aftermath of the financial crisis, regulators proposed a new methodology for calculating EURIBOR. Despite the volatility wrought by COVID-19, this methodology performed well in 2020, reflecting expectations for benchmark rates and perceived bank credit risk and capturing the indirect effects of the dislocation sustained in the FX swap market. José Manuel Amor Abstract: The onset of the global financial interbank lending market at different tenors. crisis in 2008 forced regulators and Despite the volatility wrought by COVID-19 supervisors to rethink the suitability of the in 2020, it is fair to say that the EURIBOR IBORs as benchmark rates of interest. In has surmounted a very challenging year, Europe, the FSB’s recommendations affect helped significantly by a new hybrid two key benchmark rates – EURIBOR and calculation methodology developed in the EONIA – and have resulted in the creation aftermath of the financial crisis. Specifically, of the euro short-term rate, or €STR, to replace the EURIBOR rates trended in a manner the EONIA following a period during which the that was consistent with expectations for two indices will co-exist. Importantly, benchmark rates and perceived bank credit EURIBOR must at all times and in differing risk and captured the indirect effects of the market conditions reflect the cost to banks’ dislocation sustained in the FX swap market of obtaining funding in the euro unsecured as a result of the surge in global demand 49 “ The loss of liquidity and trading volumes in the interbank markets made it harder to calculate IBORs based on actual transactions. ” for dollar funding in the early stages of the the decline in liquidity in the interbank COVID-19 crisis. unsecured funding markets), the G20 spearheaded the global reform of reference rates in 2013. The G20 tasked the Financial Backdrop for the reform of the Stability Board (FSB) to establish guidelines interbank offered rates (IBORs) and recommendations for creating a new set For decades now, the interbank offered rates of regulations that could address the current (“IBORs”) have constituted the benchmark system’s shortcomings and correct the issues interest rates for unsecured interbank lending implicit in prevailing reference rates. In 2014, at different maturities or tenors. Those rates the FSB recommended: (i) reinforcing the layer unsecured bank credit risk on top of the methodology used to calculate the reference risk-free rates and have historically provided indices, tying them wherever possible to a benchmark for setting the prices of a very real transactions and improving data supply broad range of financial contracts (loans, processes and controls (the basis for the so- derivatives and fixed-income securities). called “IBOR reform”); and, (ii) identifying alternative risk-free reference rates. The onset of the global financial crisis in 2008 forced regulators and supervisors to rethink The replacement of the IBORs with new the suitability of the IBORs as benchmark reference rates means most calculations of rates of interest. Their construction via IBORs will cease between December 2021 surveys and non-binding rates left them open and June 2023. [1] In Europe, the FSB’s to manipulation.

The EMMI’s current methodology – still implement a robust system of governance provisional – for determining the EURIBOR and set of control mechanisms to ensure rates is summed up as follows: Exhibit 1 How EURIBOR rates are determined using the EMMI’s hybrid methodology Does the panel bank have sufficient eligible transactions for the tenor in question?
