Everything you need, all in one place
You’ll find everything you need here to help prepare you for the upcoming transitions. We’ll continue to provide updates, along with best practices and guidance from our experience with market participants, the central bank and clearinghouses.
Our deep regulatory experience
The guidance we provide our clients on how to navigate regulatory reform and RFR transitions is drawn from our extensive experience of supporting transitions across the globe – including Dodd-Frank, MiFID II, Libor, F-TIIE, SHIR, SONIA, ESTR, SOFR, TONA, and beyond.
What are Risk-Free Reference Rates?
Risk-Free Reference Rates (RFRs) are interest rate benchmarks that are designed to replace older interbank offered rates (like LIBOR) and provide a more accurate and reliable reflection of the actual cost of borrowing money in financial markets. Unlike their predecessors, which were based on estimates submitted by banks, RFRs are calculated from actual transactions, making them more transparent and less susceptible to manipulation.
Each major currency has its own RFR, typically introduced to ensure the financial system's stability, accuracy and transparency. Other examples include €STR (Euro Short-Term Rate) for the Eurozone, SARON (Swiss Average Rate Overnight) for Switzerland, and TONAR (Tokyo Overnight Average Rate) for Japan. These rates are now widely used in pricing loans, bonds, derivatives, and other financial products to better reflect market conditions.
