What drives US tariffs?

Tariffs

Tariffs are taxes that a government charges on goods imported from other countries. When tariffs rise, imported products cost more. When they fall, imports get cheaper. From late 2024 through early 2026, US tariffs became one of the most powerful forces shaping the global economy, at times reaching 145% on Chinese goods.

Main drivers

What pushes tariffs up

  • Election outcomes — A change in political leadership can shift trade policy overnight, raising expectations of new or higher import taxes.
  • Retaliatory tariffs from trading partners — When one country raises tariffs, the targeted country often hits back with its own tariffs, prompting yet another round of increases in a self-reinforcing spiral.
  • Export restrictions on critical materials — When a country restricts exports of essential resources like rare earth minerals, the other side may respond by raising tariffs further.
  • Geopolitical pressure — A country may impose tariffs to punish a trading partner for actions unrelated to trade, such as buying oil from a rival nation.

What pushes tariffs down

  • Trade deal negotiations — Bilateral agreements and temporary truces are the primary way tariffs come back down, as both sides agree to suspend or reduce duties.

Historical examples

When tariffs increased

  • Election outcomes

    • November 2024 US presidential election — Early signs of a Trump victory on November 6, 2024 immediately raised expectations of higher tariffs. Copper futures dropped more than 2% as markets priced in escalating US-China tensions.

  • Retaliatory tariffs from trading partners

    • China's 34% retaliation (April 2025) — After the US unveiled a 34% tariff on Chinese imports (pushing total levies to 54%), China announced a matching 34% tariff on all US imports. This tit-for-tat cycle continued until US tariffs on China reached 145% and Chinese tariffs on US goods hit 125%.
    • Canada's 25% counter-tariffs (March 2025) — The US imposed 25% tariffs on Canadian goods, with a 10% rate on energy. Canada immediately reciprocated with 25% tariffs on US goods, deepening North American trade conflict.
    • European countermeasure signals (September 2025) — The US urged the EU to impose 100% tariffs on Chinese and Indian goods, signaling it would mirror such measures, creating another feedback loop pushing tariffs higher.

  • Export restrictions on critical materials

    • China's rare earth export curbs (October 2025) — China restricted exports of rare earth minerals and permanent magnets in response to US tariffs. The US president warned of a "massive increase" in tariffs, and copper plunged more than 4%. Days later, the US announced a 100% tariff on all Chinese goods.
    • China's broader export and investment controls (March 2025) — Beijing placed 25 US firms under export and investment restrictions and raised import taxes on American agricultural products. US tariffs on Chinese goods had already risen to 20%, prompting this retaliation, which fed back into further escalation.

  • Geopolitical pressure

    • US tariffs on India over Russian oil (August 2025) — The US doubled tariffs on Indian goods to 50% through an executive order, directly in response to India's continued imports of Russian oil. The new duties took effect on August 27.

When tariffs decreased

  • Trade deal negotiations
    • US-China 90-day truce (May 2025) — Both countries agreed to suspend most tariffs for 90 days. US tariffs on Chinese goods dropped from 145% to 30%. China lowered its tariffs on US imports from 125% to 10%.
    • US-China trade deal (June 2025) — Reports indicated the US and China agreed to a broader deal to avoid aggressive tariffs, consistent with softer language from US policymakers.
    • US-India deal (February 2026) — The US and Indian leaders agreed to cut tariffs on Indian goods to 18% from 50%, while also removing an extra 25% duty imposed earlier.

Who benefits

When tariffs rise

  • Domestic producers competing with imports — Higher prices on foreign goods make locally produced alternatives more attractive, at least temporarily.
  • Countries not targeted by tariffs — Regions outside the trade conflict can gain export share as buyers look for cheaper sources.

When tariffs fall

  • Consumers in the tariff-imposing country — Lower import taxes mean lower prices on everyday goods like furniture, toys, cars, and clothing.
  • Export-heavy economies and their currencies — When the US cut tariffs on India to 18% from 50%, the Indian rupee strengthened from record lows as the outlook for Indian textile, machinery, and raw material exports improved.
  • Manufacturers reliant on imported inputs — Lower tariffs reduce costs for materials and components, easing margin pressure and supply chain bottlenecks.
  • Global commodity markets — Oil prices fell more than 10% during peak tariff anxiety in August 2025. Lower tariffs reduce fears of global slowdown and support commodity demand.

When tariffs rise — who loses

  • Consumers facing higher prices — US inflation accelerated to 2.7% in mid-2025 as businesses passed higher import costs on to shoppers, hitting categories like furniture, toys, and automobiles.
  • The manufacturing sector — US manufacturing contracted for six straight months through August 2025 as tariffs drove up input costs, disrupted supply chains, and caused shipping delays at ports.
  • Homebuilders and construction — US building permits fell 4.7% in April 2025 to an 11-month low. Tariffs on lumber and building materials pushed up housing costs, and new duties of 10-50% on softwood lumber hit Canadian suppliers hardest.
  • Consumer confidence — By September 2025, US consumer sentiment fell to a 4-month low of 55.4. Roughly 60% of respondents cited tariffs as a key concern, and inflation expectations stayed elevated at 4.8% for the year ahead.
  • Overall economic growth in the US — The US economy shrank at a 0.3% annual rate in the first quarter of 2025, the first contraction since 2022. Businesses and consumers rushed to stockpile imports before tariffs hit, causing a 41.3% surge in imports that distorted the numbers downward.
  • Trading partner economies — The UK economy contracted 0.3% in April 2025 partly due to tariff-related global uncertainty. Canada's economy shrank at a 1.6% annual rate in the second quarter. Japan's growth slowed to just 0.1% by the fourth quarter of 2025. This synchronized slowdown amplified the damage as weaker demand in each economy reduced export opportunities for the others.
  • Central bank flexibility — Tariffs created a painful trap: prices rose while growth slowed. The US central bank could not aggressively cut interest rates to support the economy without risking more inflation from tariff-driven price increases. Canada's central bank cut its benchmark rate to 2.25% in October 2025 as tariff damage weighed on output and jobs.
  • US exporters — Retaliatory tariffs from trading partners reduced demand for American goods. New export orders fell steeply throughout the spring and summer of 2025.
