There are also quotes an official, interbank, exchange-traded. The official exchange rate quotation by the Central Bank. The official exchange rate used for accounting purposes and customs payments for the balance of payments.

Methods for determining the official exchange rate varies by country depending on the nature of the monetary system and exchange rate regime. In countries where the fixed exchange rate regime, the quotation is determined purely by administrative means. The Central Bank sets (regardless of supply and demand for currency) exchange rate against the currency of any one country to which the «tied» the currency of that country, or in relation to several currencies at once (on the basis of the «currency basket») or SDRs. At the same time the Central Bank may establish different exchange rates for individual operations (multiplicity of exchange). This method was used in the Russian Federation until July 1992.

Under the regime of «currency corridor» official exchange rate set under the «currency corridor», or at the level of the exchange (as, for example, in Russia from July 1995 to May 1996) or by daily quotations, the so-called «sliding fixation».

In some countries with underdeveloped exchange market, where the main circulation of currency transactions pass through the currency market, the official rate set at the level of the exchange.

In countries with a free currency market, where a regime of «floating» rate, depending on the prevailing supply and demand for foreign currency, central banks set the official exchange rate at the interbank level. In some industrialized countries maintained a tradition of setting the official exchange rate at the level of the exchange.

Since the bulk of foreign exchange operations in industrialized countries are carried out on-the-counter interbank market, the main course of the internal market in these countries is the interbank rate. Interbank quotation installs large commercial banks – the main operators of the foreign exchange market, supporting one another permanent relationship. They are called market makers (makers of the market).Other banks – market-users (users of the market) to apply for quotation of market makers. Interbank Foreign Exchange quotes are set by market makers by sequential comparison of supply and demand for each currency.

On the interbank rates are guided all the other members of the currency market, it is the basis of establishing rates for each currency. Exchange rate is mostly for reference.

In countries with rigid exchange restrictions and fixed exchange rate, all operations are conducted at the official rate. In some countries with underdeveloped exchange market, where the volume of currency transactions are in foreign currency exchange rate of the main foreign exchange market is the exchange quotation, which is formed on the exchange, based on the consistent comparison of bids for the purchase and sale of foreign currency (exchange fixing). Exchange rate is the basis of establishing rates, both in interbank transactions and for bank customers.
