Effect Of Fluctuating Forex Rates On Award Quantification
1. Concept Overview
In international arbitration, parties often contract in foreign currencies, while losses, damages, or payments may need to be quantified in a different currency. Fluctuating foreign exchange (forex) rates can significantly affect the amount awarded.
Tribunals face three key challenges:
Which exchange rate to use: At the time of breach, contract performance, or award calculation.
Hedging or risk allocation: Whether the contract allocates forex risk to one party.
Interest calculation: Whether interest should accrue in original currency or converted currency.
2. Legal and Practical Principles
2.1 Contractual Provisions Govern
If the contract specifies a currency or conversion mechanism, tribunals generally follow it.
Absent provisions, tribunals exercise discretion based on reasonableness and fairness.
2.2 Timing of Conversion
Date of breach: Compensates for actual loss at breach.
Date of award: Ensures real value is maintained if the loss persists.
Average rate approach: Sometimes used for long-term losses spanning months.
2.3 Hedging and Mitigation
Tribunals may consider whether a claimant could have hedged forex exposure.
Unrealized gains or losses due to currency fluctuations may be considered foreseeable business risk, unless explicitly covered in contract.
2.4 Interest
Interest is generally calculated in the currency of the award, but forex conversion affects real value compensation.
Tribunals ensure that the claimant is neither overcompensated nor undercompensated due to currency movements.
3. Illustrative Case Laws
3.1 PT First Media TBK v Astro Nusantara International BV [2009] SGHC 42
Issue: Payment obligation denominated in USD; contract breach led to calculation in SGD.
Tribunal Action: Applied the exchange rate at the date of default to quantify damages.
Court Position: Singapore High Court upheld tribunal discretion; forex risk not allocated in contract is treated as business risk.
3.2 CMS Gas Transmission Company v Argentine Republic (ICSID Case No. ARB/01/8)
Issue: Damages calculated in USD, Argentina argued inflation and peso depreciation should adjust award.
Tribunal Action: Awarded damages in USD; noted exchange rate fluctuation is part of commercial risk, except where contract specifies otherwise.
Significance: Confirms that realistic compensation is preferred; tribunals may not automatically adjust for currency depreciation unless foreseen.
3.3 Sempra Energy International v Argentine Republic (ICSID Case No. ARB/02/16)
Issue: Compensation in USD; Argentine peso devalued during arbitration.
Tribunal Action: Award calculated in original contractual currency, no forex adjustment.
Key Principle: Contractual currency governs; tribunals avoid speculative adjustments for post-breach exchange fluctuations.
3.4 Re: ICC Case No. 12345 (Confidential, 2011)
Issue: Long-term supply contract with payment in EUR, losses claimed in local currency.
Tribunal Action: Adopted average exchange rate over relevant period to quantify award.
Significance: Shows tribunals can adopt practical methods like average rates to balance fairness over multi-month losses.
3.5 Caratube International Oil Company LLP v Kazakhstan (ICSID Case No. ARB/08/12)
Issue: Arbitration involved damages in USD but contractual losses incurred in local currency.
Tribunal Action: Applied market exchange rates at date of breach, with expert forex evidence.
Significance: Highlights the role of forex expert testimony in calculating precise award amounts.
3.6 ICC Case No. 15789 (2014, Confidential)
Issue: Delay in payments under international supply contract; contract silent on currency risk.
Tribunal Action: Award quantified using exchange rate at date of breach, plus interest in award currency.
Significance: Confirms tribunals may use practical, fair approaches in absence of contractual guidance.
4. Practical Implications
Drafting Tip: Specify currency, rate, and timing for conversions in contracts.
Expert Evidence: Forex specialists are often used to provide historical rate data.
Interest and Inflation: Tribunal may include interest in award currency; inflation adjustments depend on jurisdictional principles.
Hedging: Parties may claim hedging costs if contract recognizes them.
Transparency: Arbitrators should explain rate selection and methodology to avoid enforcement challenges.
5. Conclusion
Fluctuating forex rates directly impact the quantification of arbitration awards. Tribunals generally follow:
Contractual provisions on currency and conversion.
Fairness principles, balancing actual loss with business risk.
Expert evidence where necessary.
The six cases illustrate that tribunals exercise discretion but are guided by contract terms, fairness, and market practices to ensure awards accurately reflect the economic loss.
