At the time, the Moscow Interbank Currency Exchange (or "MICEX") set a daily "official" exchange rate through a series of interactive auctions based on written bids submitted by buyers and sellers. When the buy and sell prices matched, this "fixed" or "settled" the official MICEX exchange rate, which would then be published by Reuters. The MICEX rate was (and is) commonly used by banks and currency dealers worldwide as the reference exchange rate for transactions involving the Russian ruble and foreign currencies.
