# Smoot-Hawley Tariff The **Smoot-Hawley Tariff Act** (formally the Tariff Act of 1930) was signed by President [[Herbert Hoover]] on **June 17, 1930** in the second year of the [[Great Depression]]. It raised duties on about 890 of the roughly 3,300 dutiable items in the tariff schedule and pushed the average duty on dutiable imports to **59.1% by 1932** (USITC), among the highest protective levels in American history. The act is one of the most thoroughly-studied policy failures in American economic history and the canonical 20th-century case study in protectionism's macroeconomic costs. The act's congressional drafters were Senator **Reed Smoot** (R-UT, chair of [[Senate Finance Committee]]) and Representative **Willis C. Hawley** (R-OR, chair of House Ways and Means). Their original 1929 legislation was a narrow agricultural-tariff bill aimed at supporting struggling farmers; through the legislative process the bill accumulated tariff increases on hundreds of additional industrial categories as logrolling among Republican congressional members exchanged tariff support for tariff support. By the time it reached Hoover's desk, Smoot-Hawley raised duties across both farm and industrial schedules. > [!note] How many goods? > The official count is narrower than the popular one. Hoover's signing statement (15 June 1930) put it at "about 890 increased, 235 decreased, and 2,170 untouched" out of "about 3,300" dutiable items — increases on 27% of items, covering about 22.5% of imports by value. The US Tariff Commission's 1931 tally gave 890 increases and 235 decreases. The widely repeated figure of "over 20,000 imported goods," traced to F. W. Taussig's 1931 *Tariff History of the United States*, does not match these official tallies of schedule items and should not be read as a count of tariff-line increases. **1,028 American economists signed a public petition opposing the act** in May 1930 — including Irving Fisher, James Harvey Rogers, Frank Taussig, and other major figures of the era — predicting that the tariff would deepen the Depression. [[Henry Ford]] visited Hoover personally to urge a veto, calling the act "an economic stupidity." Hoover signed it anyway. The political pressure from congressional Republicans was operationally decisive. ## Consequences **Global retaliation.** Within months of Smoot-Hawley's signing, U.S. trading partners enacted retaliatory tariffs on American exports. **Canada** imposed retaliatory tariffs on American goods in 1930-1931; **France**, **Britain**, **Germany**, **Italy**, and others followed. **Global trade collapsed** — between 1929 and 1933, world trade volume contracted by approximately 66%, far more than the (already severe) ~25-30% GDP contraction in the U.S. Whether Smoot-Hawley *caused* the post-1930 trade collapse vs. merely *accompanied* it has been contested in the empirical economics literature; the consensus view through the late 20th century treated Smoot-Hawley as a major contributor to the Depression's depth and breadth. **Political consequences.** The 1930 [[1930 Midterm Elections]] — held five months after Smoot-Hawley's signing — produced massive Republican losses; Democrats took the House operationally during the lame-duck period through special elections. The 1932 [[1932 Presidential Election]] produced [[Franklin D. Roosevelt]]'s landslide; FDR's 1934 **Reciprocal Trade Agreements Act** reversed Smoot-Hawley by authorizing executive-branch negotiation of bilateral tariff reductions. The post-1934 American trade-policy framework — bilateral and multilateral negotiation toward lower tariffs — held until the 2018 Trump-era tariff revival. ## Right-wing relevance Smoot-Hawley is contested terrain in right-wing political-economic argument: **1. The mainstream-conservative consensus view.** For most of the 1934-2016 period, mainstream American conservative economics treated Smoot-Hawley as a canonical example of protectionism's macroeconomic costs — invoked in free-trade arguments, opposed-to-tariff arguments, and broader cases against trade-policy interventionism. The Reagan-era Republican Party operated within this framework; the Bush 41, Bush 43, and Romney-era Republican economic-policy mainstream operated within it. **2. The post-2016 protectionist revival.** Trump-era tariff politics — the 2018 China tariffs, the 2025 [[Liberation Day Tariffs]] — operate against the post-1934 consensus and have rehabilitated tariff politics that the post-Smoot-Hawley framework had treated as historically discredited. The right-wing intellectual response to Smoot-Hawley has shifted since 2016, with various commentators arguing that the standard Smoot-Hawley-caused-the-Depression-deepening framework overstates the causal contribution. The empirical-economics literature on this is contested in detail; the post-2016 right-wing revisionist treatment is uneven in quality but operationally important. **3. The McKinley-tariff lineage and the Smoot-Hawley discontinuity.** The right-wing political-historical claim that contemporary tariff politics is in the McKinley-tariff tradition has to navigate the awkward 1930 Smoot-Hawley experience — a Republican-led tariff increase signed by a Republican president that accompanied the deepest American depression. The conventional right-wing post-1934 response was to treat Smoot-Hawley as an aberration; the post-2016 right-wing response has been more uneven. ## The act is not historical — Section 338, revived in 2026 The most important fact about the Tariff Act of 1930 in the 2020s is that **it is still on the books, and one of its dormant provisions is now a live instrument of American trade policy.** On **20 July 2026** the administration invoked **Section 338** of the act to impose 50% duties on Canadian motor vehicles, dairy, and alcoholic beverages — 554 tariff lines across three proclamations. The duties took effect **22 August 2026**. It was the **first time any president had used Section 338 to impose tariffs**; the authority had gone essentially unexercised since the 1930s and 1940s, and trade lawyers described it as a statute obscure enough that many did not know it survived. Section 338 authorizes tariffs against countries found to discriminate against US commerce. Two features made it attractive where other authorities had failed: the duties stack **on top of** all existing tariffs, and **[[USMCA]] preferential status does not exempt the goods**. Its revival followed the Supreme Court's February 2026 holding in *Learning Resources, Inc. v. Trump* that IEEPA authorizes no tariffs at all — when the broad emergency authority was closed off, the search moved to older and narrower statutes still sitting unrepealed in the code. Canada's answer arrived on the same axis as 1930: retaliation. [[Mark Carney]] announced counter-tariffs on more than 700 American products, C$27.6 billion matched dollar-for-dollar to the American action, effective **8 September 2026**. The historical rhyme is exact enough to be uncomfortable. The 1930 act's defining consequence was that Canada and the European powers retaliated and world trade collapsed by roughly two-thirds. In 2026 the *same statute* produced a Canadian retaliation package within a day of taking effect. The difference is that in 1930 the retaliation was a response to a tariff wall; in 2026 it is a response to a single provision of the same law, used for the first time, against a treaty partner. For this vault the lesson is narrower than the economics debate: **repeal is rarer than disuse.** A statute that goes ninety years without being used is not a dead letter — it is an option held in reserve, and the constraint on its use was norm rather than law. ## Connections - [[Herbert Hoover]] — Signed the act despite 1,028 economists' public opposition. - [[Great Depression]] — The macroeconomic context the act accompanied and (per the conventional view) deepened. - [[Liberation Day Tariffs]] — The April 2025 Trump-era tariff campaign that operates against the post-1934 free-trade consensus. - [[USMCA]] — where the Section 338 revival is playing out - [[Mark Carney]] — the retaliating counterpart - [[Tariffs]] · [[Protectionism]] — the concept pages - [[US Treaty and Organization Withdrawal Timeline]] — the 2026 sequence in date order --- *Filled in 2026-05-16 as part of the post-midterm-elections stub-candidate sweep.*
