The Tariff Act of 1930 (often called Smoot–Hawley) raised U.S. import duties in an effort to protect domestic producers during the early Great Depression. The law became a symbol of protectionism and helped set the political and economic backdrop for later efforts to reduce tariffs through negotiated agreements.
The House of Representatives passed H.R. 8687, the bill that became the Reciprocal Trade Agreements Act (RTAA). The measure marked a major policy shift by supporting negotiated, mutual tariff reductions rather than across-the-board tariff increases.
President Franklin D. Roosevelt signed the Reciprocal Trade Agreements Act, amending the Tariff Act of 1930 to let the executive branch negotiate bilateral tariff agreements. The RTAA allowed tariff reductions (and increases) within limits—commonly described as up to 50%—and helped move U.S. trade policy toward reciprocal bargaining instead of unilateral protectionism.
The United States and Cuba signed a reciprocal trade agreement soon after the RTAA became law. Early agreements like this one focused heavily on agricultural and commodity trade and served as practical tests of the RTAA’s new negotiating approach.
As the initial authorization period neared expiration, Roosevelt publicly asked Congress to renew the authority to negotiate reciprocal trade agreements. His statement framed renewal as a response to high global trade barriers and discriminatory trade blocs that had grown in the early 1930s.
During World War II, U.S. trade policy increasingly linked tariff liberalization to broader postwar economic planning. The push for rules-based trade and currency stability set the stage for international institutions and agreements that would follow the war.
The Bretton Woods Agreements Act authorized U.S. participation in the International Monetary Fund (IMF) and the International Bank for Reconstruction and Development (World Bank). While not a tariff law, it supported a larger goal shared with RTAA-era policy: rebuilding an international economic order that encouraged trade and reduced destructive barriers.
U.S. officials signed the Bretton Woods Fund and Bank agreements, moving the postwar economic framework from legislation toward implementation. These institutions were designed to support monetary stability and postwar reconstruction, conditions often seen as necessary for expanding international trade.
Representatives of 23 countries signed the Final Act of the General Agreement on Tariffs and Trade (GATT). GATT aimed to reduce tariffs and set basic rules for trade, building on the RTAA model but shifting the center of gravity toward multilateral (multi-country) negotiations.
The United States and other countries committed to the Protocol of Provisional Application, agreeing to apply GATT on an interim basis. This step mattered because it made the new tariff concessions and trade rules operational quickly, even before a more permanent institutional structure existed.
Under the provisional application approach, the United States began applying GATT and its tariff concessions as of January 1, 1948. This marked a practical transition from RTAA-era bilateral bargaining toward a broader system of negotiated tariff reductions under shared multilateral rules.
By the late 1940s, U.S. tariff liberalization was increasingly organized through GATT rather than primarily through RTAA-style bilateral deals. The RTAA’s core legacy from 1934–1945 was institutional: it normalized negotiated tariff cutting and helped shift trade policy leadership toward the executive branch, paving the way for postwar multilateral trade governance.
