North American Free Trade Agreement (NAFTA)

The North American Free Trade Agreement (NAFTA) was a trade agreement between the United States, Canada and Mexico that created one of the world's largest free trade areas. Signed on 17 December 1992 by President George H. W. Bush, Prime Minister Brian Mulroney and President Carlos Salinas de Gortari, it entered into force on 1 January 1994. It phased out most tariffs among the three countries over 15 years and set rules on investment, services, intellectual property and dispute settlement.

NAFTA built on the 1989 Canada–United States Free Trade Agreement and was the first major free trade pact joining two rich economies with a developing one. It was replaced on 1 July 2020 by the United States-Mexico-Canada Agreement (USMCA). It remains a reference point in debates about free trade, jobs and globalization.

Picture three neighbouring shops that decide to stop charging each other a fee every time goods move between them. Parts can now travel back and forth cheaply, so a product might be partly built in one shop, finished in another and sold in the third. Customers get lower prices and more choice, and the shops reorganise around what each does best.

But some workers in each shop lose out when their job moves next door, while others gain new work. NAFTA was that arrangement on a continental scale, which is why it was praised by some and blamed by others for decades.

• Tariff elimination. Duties on most goods traded among the three were removed, some immediately and the rest over periods of up to 15 years, ending in 2008 for the most sensitive farm products.
• Rules of origin. Rules of origin decided which goods qualified; for cars, 62.5% regional value content was required.
• Investment (Chapter 11). Foreign investors could bring claims directly against host governments before international arbitration panels, a mechanism known as investor-state dispute settlement.
• Trade remedies (Chapter 19). Binational panels reviewed anti-dumping and countervailing duty decisions instead of national courts.
• Services, finance and intellectual property. Rules opened service markets, including banking, and protected intellectual property (IP).
• Side agreements. The North American Agreements on Labor Cooperation and Environmental Cooperation, added in 1993 under President Bill Clinton, created commissions to monitor enforcement of national labour and environmental laws.

Trade among the three grew quickly. The Office of the United States Trade Representative reported that trilateral trade rose from $289.3 billion in 1993 to $623.1 billion in 2003, and it kept rising afterwards. Supply chains became deeply integrated, especially in cars, electronics and agriculture, with parts crossing borders several times before final assembly. Foreign direct investment (FDI) into Mexico grew, and Mexican export-assembly plants known as maquiladoras expanded. Studies using the gravity model of trade and general-equilibrium models generally found large effects on trade flows but small net effects on overall US and Canadian GDP.

Soon after NAFTA began, Mexico suffered the December 1994 peso crisis, a currency crisis that led to a sharp currency devaluation and a rescue package from the United States and the International Monetary Fund (IMF). Economists still debate how far the crisis and its aftermath shaped NAFTA's early results.

NAFTA was politically contested from the start. In the 1992 US presidential campaign Ross Perot warned of a "giant sucking sound" of jobs moving to Mexico. Later estimates diverged widely. Labour-aligned researchers, such as at the Economic Policy Institute, estimated hundreds of thousands of US jobs displaced by the rising trade deficit with Mexico, while the US Congressional Budget Office and the US International Trade Commission found small overall effects on employment and GDP. Academic studies found that wage growth slowed for workers in the industries and towns most exposed to Mexican competition, even if national effects were modest.

In Mexico, supporters pointed to export growth, investment and lower consumer prices; critics pointed to the displacement of small maize farmers facing subsidised US corn, slow wage growth and uneven regional gains between the industrial north and the poorer south, a recurring theme in studies of economic inequality. Canadian debates centred on sovereignty and investor-state cases. Environmental and labour groups argued that the side agreements lacked teeth, while business groups and many economists saw NAFTA as a model of regional integration and a spur to productivity.

In 2017 the Trump administration, which had called NAFTA a bad deal for US workers, began renegotiation. The result, signed on 30 November 2018 and amended by a protocol on 10 December 2019, raised auto rules-of-origin requirements, added labour enforcement and digital trade rules, curtailed investor-state arbitration and added a review clause. It entered into force on 1 July 2020 as the USMCA (known as CUSMA in Canada and T-MEC in Mexico), ending NAFTA after 26 years. The episode showed how a trade bloc could be reopened by a member threatening withdrawal, and NAFTA remains a case study in the politics of protectionism and trade liberalisation.
