Financial Derivatives Arbitration
1. Nature of Financial Derivatives Contracts
Financial derivatives are contracts whose value depends on an underlying asset (e.g., interest rates, currencies, commodities, or indices).
Common derivatives:
Interest Rate Swaps (IRS)
Credit Default Swaps (CDS)
Currency swaps
Options and futures
Most transactions are governed by:
ISDA Master Agreement
Schedule and Credit Support Annex (CSA)
2. Common Types of Disputes
(a) Mis-selling and Suitability Claims
Investors allege they were not properly informed of risks.
(b) Valuation Disputes
Disagreement over mark-to-market valuation or close-out amounts.
(c) Termination and Close-Out Netting
Disputes after early termination events.
(d) Market Disruption Events
Whether extraordinary events justify suspension or adjustment.
(e) Collateral and Margin Calls
Failure to meet margin requirements under CSA.
(f) Illegality and Regulatory Violations
Contracts challenged due to regulatory breaches.
3. Legal Issues in Derivatives Arbitration
(i) Enforceability of ISDA Close-Out Netting
Close-out netting allows aggregation of obligations upon default.
Key issue:
Whether netting is enforceable across jurisdictions.
(ii) Misrepresentation and Risk Disclosure
Tribunals examine:
Whether banks adequately disclosed risks
Sophistication of the counterparty
(iii) Interpretation of Standard Form Contracts
ISDA agreements are highly standardized; disputes focus on:
Definitions (e.g., “Market Quotation”)
Event of Default clauses
(iv) Illegality and Ultra Vires Transactions
Some entities (e.g., municipalities) may lack authority to enter derivatives.
(v) Calculation of Damages
Includes:
Replacement costs
Lost profits
Hedging losses
