Meaning
Discrepancy between nominal financial figures and actual purchasing power arises from fluctuations in foreign exchange rates. A currency distortion obscures the underlying performance of a business by introducing gains or losses that do not relate to operational efficiency. This effect is most pronounced for organizations that operate across multiple borders or hold debt in a denomination different from their revenue.
It complicates the comparison of year over year results.
Valuation Error
Assets held on a balance sheet may appear to grow or shrink based solely on the movements of the local currency. This currency distortion can lead to an overstatement of wealth when the local unit strengthens against the reporting currency. Such a change does not represent a real increase in the productive capacity of the asset.
It instead represents a translation effect that may reverse in the next period.
Reporting Bias
Financial statements often aggregate data from several regions into a single home currency. When one region experiences high inflation or a devalued currency (the consolidated view becomes skewed).
Hedging Requirement
Managing the risk of exchange rate volatility requires the use of financial instruments. These tools carry their own costs and complexities (which must be factored into the overall cost of doing business). A failure to hedge can lead to sudden liquidity crises if the currency moves sharply against the organization.
