LIBOR fallbacks meaning

What does LIBOR fallbacks mean?
libor fallbacks are the contractual terms that govern what happens to interest and other calculations when LIBOR is not available, permanently ceases or is declared non-representative. They set the trigger events, the replacement benchmark (commonly a near risk-free rate such as SONIA), any spread adjustment to preserve economics, and mechanics such as observation shifts and conforming changes. The expression is descriptive rather than a defined statutory term, but operates alongside the UK and EU Benchmarks Regulation regimes and regulatory powers. In practice, fallbacks differ by product: - Derivatives typically rely on the ISDA IBOR Fallbacks (including the Index Cessation Event and fixed spread adjustments). - Loan agreements use LMA‑style “replacement of screen rate” or waterfall clauses to transition to RFRs, often with agent determination and amendment mechanics. - Bonds and securitisations use benchmark replacement provisions or consent solicitations. Across England & Wales, Scotland, Northern Ireland and Ireland, usage is broadly consistent. In the UK, the FCA has supported legacy contracts with temporary “synthetic LIBOR” under the onshored Benchmarks Regulation; in Ireland, the EU Benchmarks Regulation applies without a synthetic LIBOR solution, so outcomes depend more on the contract terms. Robust fallbacks are essential to mitigate value transfer and litigation risk.

This Checklist This Checklist presents, in a tabular format, the matters to address when preparing a loan that references a compounded risk-free rate (RFR) such as the Sterling Overnight Interbank Average Rate (SONIA), calculated in arrears. It explains the purpose of the key provisions, highlights issues to weigh up, and offers drafting pointers and practical guidance for practitioners. For further analysis, see Practice Note: Interest provisions in risk-free rate based loan agreements.

The LMA’s recommended form documentation, with accompanying user guides and commentary, is accessible to LMA members on its website. While the Checklist is prepared on the basis of LMA-style documentation, the guidance will also be relevant to bilateral transactions and agreements using other loan forms.

USD LIBOR cessation: High Court implies reasonable alternative rate for preference share dividends; CME Term SOFR + ISDA spread chosen; no redemption (Standard Chartered v Guaranty Nominees) (England and Wales)

Standard Chartered plc v Guaranty Nominees Ltd and other companies [2024] EWHC 2605 (Comm) What are the practical implications of this case? In a notable ruling for the banking and finance sector, the High Court implied a term into an offering circular for preference shares, providing that a ‘reasonable alternative rate’ would apply after the cessation of USD LIBOR. The circular had linked dividends to three‑month USD LIBOR. Although it set out fallbacks for occasions when LIBOR was not published, those provisions proved unworkable once LIBOR ceased entirely. The court then addressed what the reasonable alternative ought to be, determining that CME Term SOFR together with the International Swaps and Derivatives Association (ISDA) Spread Adjustment—i.e., the rate published as synthetic USD LIBOR prior to 1 October 2024—was the most suitable rate on the facts. While the dispute focused on calculating dividend rates for preference shares, the decision is of broader interest to the finance market...
