In recent years, the U.S.A. has been following a rather strict policy against Iran. Such behaviour is explained by Tehran's interest in the nuclear program, that actually, according to the experts, masks the weapon development. The next punitive measures concern the Iran's national currency – the rial. U.S. President Barack Obama has signed a decree on reinforcement of economic restrictions on this Islamic country the other day. The decree governs the financial institutions, which sell and buy large amounts of rials or hold deposits in this currency. The analysts are sure that this tactic will provoke the bulk sale of the rial followed by its fall. Since the beginning of the last year the currency has already lost half of its value. Moreover, the U.S.A. authorities keep under control the supply of goods and services related to the Iranian automotive engineering. Currently, this field is the major revenue provider of the country. Considering the fact that many of the engineering components may be used in arms manufacturing, such suppliers are subject to this restrictions. These sanctions do not apply to those companies and organizations that are constructing the pipeline, which is supposed to deliver the Azerbaijani gas to Europe and Turkey. The gas line crosses the Iranian territory.
