The official exchange rates of foreign currencies against the UAE Dirham are determined by the Central Bank of the UAE on a daily basis. Since the UAE dirham is pegged to the U.S. Dollar at a fixed rate of 3.6725, the rates for other currencies are calculated through cross-currency exchange rates based on international market data. These rates are mandatory for the calculation of Value Added Tax (VAT), customs duties, and official financial reporting within the country, while serving as a reference benchmark for commercial transactions and private contracts.
