The authorization of the RTAA was granted for three years from the date of entry into force of the RTAA (June 12, 1934).

Convinced that the recovery would come from measures at home rather than abroad, he assured Congress of the passage of a series of far-reaching domestic economic reforms that would be known as the first New Deal. His doubts about the ability of foreign economic policy to contribute to the domestic recovery were reflected in his approach taken at the London Economic Conference.
In June 1933, representatives of 66 countries met in London to emerge from the depression by cooperating in areas such as reducing trade barriers and stabilizing exchange rates. Countries that remained on the gold standard, such as France, tried to convince countries that had left the gold standard, notably the United Kingdom (September 1931) and the United States (April 1933) to agree on the stabilization of the nominal values of their currencies. The chances of success were already slim when Roosevelt on July 3 dismissed such an agreement as a „purely artificial and temporary experiment,“ claiming that a „healthy internal economic situation“ was more important to a country`s prosperity than the external value of its currency. It gave the president the power to negotiate bilateral and reciprocal trade agreements with other countries and allowed Roosevelt to liberalize U.S. trade policy around the world. It is widely attributed that it use opened the era of liberal trade policy, which lasted throughout the twentieth century.  7.
