LIBOR Transition and Replacement Rate solutions

ISDA Fallback rates

LSEG is an authorized distributor for ISDA IBOR Benchmark Fallback rates on its products.

ISDA Fallback rates play a pivotal role for OTC Derivatives within the LIBOR transition and wider IBORs reform

ISDA Fallback rates are relevant to derivatives trades referencing a specific IBOR and play a key role in the event of a permanent cessation of that interbank offered rate (IBOR). Specific fallback rates are set out in the 2006 ISDA Definitions. ISDA released robust Fallback rates that would apply in the event of a permanent cessation of a key interbank offered rate (IBOR).

What are ISDA Fallback rates?

More than $350 trillion worth of financial instruments reference LIBOR – the benchmark that is expected to cease at the end of 2021. Current financial contracts documentation does not include the relevant language to cover the end of a benchmark. So, as LIBOR ends, contracts will not have a new rate to fall back on or rely on. But the new available ISDA protocol and its adoption enable a fallback rate to be inserted, covering the move out from LIBOR or any other benchmark.
