Libor Legacy Litigation.
🔹 1. Concept of LIBOR Legacy Litigation
LIBOR (London Interbank Offered Rate) was the benchmark interest rate at which major global banks lent to each other. LIBOR Legacy Litigation refers to the lawsuits and regulatory actions arising from historical manipulation of LIBOR, which was discovered around 2012.
Key Points:
Banks manipulated LIBOR submissions to benefit trading positions or appear financially healthier.
The manipulation affected derivatives, loans, mortgages, and bonds worldwide.
Litigation can be categorized into:
Civil claims: by corporate, institutional, or retail borrowers
Regulatory enforcement actions: fines and penalties from authorities
Class actions: representing groups of affected parties
🔹 2. Background and Regulatory Framework
Financial Conduct Authority (FCA) – UK regulator overseeing LIBOR reforms
U.S. Department of Justice (DOJ) & Commodity Futures Trading Commission (CFTC) – prosecuted manipulation in the U.S.
European Commission (EC) – investigated breaches in Europe
Legacy Issues:
Many contracts referenced LIBOR for interest calculation.
Post-2012, banks faced civil suits claiming damages from artificially depressed or elevated rates.
Replacement rates (SOFR, SONIA, €STR) are now used, but legacy contracts still trigger disputes.
🔹 3. Nature of Claims in LIBOR Litigation
Fraud and Misrepresentation
Banks misreported rates to the market.
Unjust Enrichment
Profiting from trades tied to manipulated LIBOR.
Breach of Contract / Fiduciary Duty
Manipulation affected clients who relied on LIBOR in contracts.
Price Manipulation and Market Distortion
Investors claim damages for distorted interest payments.
Affected Parties:
Corporates (loan and derivative counterparties)
Hedge funds and institutional investors
Retail mortgage borrowers in some regions

Global coordination of enforcement – U.S., UK, EU authorities acted jointly on LIBOR violations.
