Foreign exchange rates have seen a major currency fluctuation over the past few years. For importers and exporters, any significant movement in currency fluctuation values has a big impact on profit margins, especially when buying supplies in high-value currency and selling in low value. Currency fluctuations and exchange rates have a tremendous impact on the amount that an expatriate receives in compensation. Plus, it greatly affects the amount of the cost-of-living allowance that companies pay their expatriates.
