Meaning
Contractual clauses that allow a seller to adjust prices in response to major fluctuations in foreign exchange rates. In international supply agreements, currency pass through mechanisms protect the supplier against the erosion of profit margins when their costs are in a different currency than their revenue. These mechanisms are typically limited to major shifts beyond a predefined neutral band.
Trigger Point
Activation of the clause usually depends on a specific percentage change in the exchange rate over a set period. If the variance remains within the neutral band, currency pass through mechanisms are not engaged, and the risk remains with the seller. This ensures that minor day-to-day fluctuations do not result in constant price changes.
Adjustment Formula
Calculations are based on a transparent index, such as the closing rate from a central bank. Once the threshold is met, currency pass through mechanisms apply a mathematical formula to the unit price to reflect the new cost reality. This might include a lag period to allow the buyer to adjust their downstream pricing.
The formula often distinguishes between the portion of the cost subject to foreign exchange risk and the local overheads that remain unaffected.
Margin Protection
Maintaining a stable net income is the primary objective for firms operating across different currency zones. Without currency pass through mechanisms, a sudden devaluation of the buyer’s currency could make an existing contract unsustainable for the exporter. This protection allows for longer-term commitments in volatile economic environments.
