Is Donald Trump serious about tariffs? This question has loomed over not just global markets but the whole world of economics.

The U.S. president-elect has stated that he would sign an executive order for a 25% tariff on all goods imported from Canada and Mexico. He has also vowed to levy a 10% tariff on products from China "above any additional tariffs." Trump has previously pledged a 60% tariff on certain Chinese goods and has even considered a 200% tax on specific car imports.

Tariffs are a cornerstone of Trump’s economic agenda. He sees them as a way to protect domestic producers from foreign competition and to promote job growth in the United States.

However, tariffs aren’t just about trade. Trump is wielding them as a diplomatic tool to pressure Mexico, Canada, and China to change their policies on migration and the crackdown on illegal drug trafficking.

The critical question is: will these measures backfire on the U.S. economy.

How do tariffs work? Tariffs are taxes on imports, imposed by the government on companies bringing goods into the country. Although technically paid by U.S. importers, these costs are often passed on to consumers in the form of higher retail prices. This means American households ultimately bear the burden.

Trump’s proposed tariffs could exacerbate inflation, forcing Americans to pay more for goods like shoes, toys, and food. If inflation surges, the Federal Reserve may need to raise interest rates, which could strengthen the dollar. However, higher tariffs could also weaken economic growth by increasing costs for businesses and consumers, potentially softening the dollar over time.

Tariff-related economic uncertainty doesn’t just affect prices — it ripples through global financial markets. For example, currency traders closely monitor major forex pairs such as EUR/USD and USD/JPY, as tariff policies can significantly influence exchange rates.

A stronger U.S. dollar, driven by higher interest rates or economic resilience, might pressure exporters by making American goods more expensive overseas. Conversely, a weaker dollar could offer some relief to exporters but might signal broader economic concerns.

In the long term, tariffs risk reducing the global competitiveness of U.S. companies and triggering retaliatory measures from trade partners, further straining the economy.

While Trump views tariffs as a tool to gain leverage in foreign relations and generate revenue to offset tax cuts, their broader economic impact remains uncertain. Whether they will truly protect U.S. producers or ultimately hurt American consumers is still up for debate.
