Introduction

The transition from LIBOR (London Interbank Offered Rate) to SOFR (Secured Overnight Financing Rate) is a pivotal shift in the global financial landscape, particularly regarding bond basis swaps. As of 2023, the global bond market is valued at approximately $128 trillion, with a significant portion of this market relying on benchmark rates like LIBOR. According to the International Swaps and Derivatives Association (ISDA), more than $370 trillion of notional value in derivatives is expected to transition to SOFR by 2026. This report delves into the top 20 countries and entities affected by the SOFR vs. LIBOR transition, highlighting their market positions and implications for the financial sector.
