Technological advancements in the late 20th century had a substantial role in shaping economic development in the Americas. The rise of the internet and advancements in communication technology facilitated globalization and the spread of neoliberal ideas. In North America, particularly in the United States, the technology boom led to the development of Silicon Valley and a shift towards a knowledge-based economy. This also allowed for the expansion of financial markets and the introduction of new financial instruments. In Latin America, technology helped to modernise industries and integrate them into the global economy, although the benefits were often unevenly distributed, favouring urban over rural areas.

Inflation was a major issue for many countries in the Americas during the 1980s and 1990s. Countries employed various strategies to combat it, including tightening monetary policy by raising interest rates, which was widely used in the United States under Federal Reserve Chairman Paul Volcker. In Latin America, countries like Argentina attempted to stabilise their economies by pegging their currencies to the dollar, though this sometimes led to further issues, such as in the Argentine economic crisis. Additionally, implementing fiscal austerity measures to reduce government deficits was a common approach encouraged by the IMF.

Economic challenges such as unemployment, inflation, and poverty exacerbated by the debt crisis and structural adjustment programs led to significant migration within and from the Americas. In Latin America, rural populations facing economic hardship due to liberalisation and modernisation of agriculture moved to urban areas in search of better opportunities, leading to the rapid expansion of urban slums. Internationally, economic instability and lack of opportunities pushed many to migrate to the United States and Canada, contributing to the rise in economic migrants and undocumented workers in North America during this period.

Economic policies during this period often had detrimental effects on indigenous populations in the Americas. Neoliberal reforms led to the privatisation of land and natural resources, many times displacing indigenous communities and disrupting traditional lifestyles. For instance, in countries like Brazil and Mexico, the emphasis on export-oriented growth and industrialisation led to environmental degradation of lands that indigenous peoples depended on for their livelihoods. Additionally, the reduction in public spending on healthcare and education disproportionately affected indigenous populations, who often relied more heavily on these services due to systemic inequalities.

The economic policies of the United States had a considerable domino effect on the Americas, particularly through the promotion of the Washington Consensus, which advocated for deregulation, free trade, and privatisation. This set of policies was heavily endorsed by U.S.-based international organisations like the IMF and the World Bank, influencing Latin American countries to adopt similar neoliberal economic models. The U.S. also directly impacted its neighbours through trade agreements like NAFTA, which linked Canada, Mexico, and the U.S. in a trilateral trade bloc, significantly altering trade flows and economic practices in the involved countries.
