The regulations of 7 September 1946 were the first devaluation decisions of the Turkish Economy, which had important effects on the following periods. Although the internal factors were influential, the political and economic winds of change that dominated the world economy after the Second World War with the leadership of the U.S.A. was the main motivator of this operation. The reasons for these decisions were stated as increasing the production, obtaining a healthy structure of foreign trade and being the member of he International Monetary Fund (I.M.F.). But due to not reaching the desired goals during its application, especially in the production and foreign trade fields, the decisions were harshly and comprehensively criticized. As a result, the devaluation of 7 September 1946 brought a mentality of rapid liberalization of the country’s foreign trade, but due to not making sufficient political and economic analysis, the 1946 decisions can be evaluated as a policy that were not successful in its basic subjects.
