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).

Distinguish quotes:
– The lines are used in most countries (including Russia). When direct quotation cost per unit of foreign currency expressed in national currency unit (for example, U.S. $ 1 = 29.64 RUR):
– Indirect, the unit adopted a national currency, the rate of which is expressed in a certain amount of foreign currency. Indirect quotation is used in the UK, since 1987, and in the U.S. (for example, 1 RUR = 0.034 U.S. dollar).
Between direct and indirect quotations of the inverse relationship exists:
The display of exchange rates of a large bank of any country is induced by the dollar against other currencies that is, represented by direct quotation.
For the British pound has historically maintained an indirect quotation, so the string GBP in this table is read as follows:
1 pound = 1.62 U.S. dollar
– Cross-rate is the ratio between the two currencies in relation to third currencies.
For example, on April 10, 2012 Bank of Russia[38] set for accounting purposes and customs payments the following rates:
1 U.S. dollar = 29.64 RUR.
