What is a Tariff
- They are taxes imposed on goods purchased from other countries. They are usually a percentage of the value of a product. A 10% tariff on goods from most countries would mean a $1 tax on a $10 product, bringing the total cost to $11. A 145% tariff on some Chinese goods would increase the cost of a $10 product to $24.50. Companies that bring foreign goods into the US have to pay this tax to the government. They can pass some or all of the increased cost on to customers.
Trump’s for Tariffs
- It is used to protect domestic production and increase the competitiveness of domestic producers by making imported goods more expensive. For example, a 25% tariff on imported vehicles in the US could be aimed at supporting the American automotive sector.
- It is used to generate revenue for the state budget. For example, Trump expects annual revenues of 600-700 billion USD from tariffs. They are used to reduce trade deficits. In 2024, the US imported 440 billion USD from China while exporting only 145 billion USD; tariffs aim to close this gap
- Tariffs are also used to coerce countries on political economic issues. For example, Trump used the threat of tariffs in 2019 to persuade Mexico to stop the influx of migrants. Under the slogan “America First”, Trump aims to reduce the US trade deficit and stimulate domestic production.
Tariffs
- Since Trump’s inauguration in January, there have been many announcements of tariffs and other countries have scrambled to respond.
- The first announcement came in 2024, when Trump promised to revitalize the “American dream” with tariffs. Starting on January 20, 2025, he imposed tariffs on multiple products (steel, aluminum) on many countries such as Mexico and Canada. The tariffs imposed on nearly 60 countries came into force on April 9. China was among these countries. The US is currently running a trade deficit with China. In 2024, the US imported far more goods from China ($440 billion) than China imported from America ($145 billion). These trade barriers have helped reduce the amount of goods the US buys from China from 21% of America’s total imports in 2016 to 13% in 2024.
- On April 2, 2025, which Trump called “Independence Day”, a 10% minimum tariff was imposed on 185 countries, with tariffs of 125% on China and 20% on the EU.
- Trump then announced a 90-day pause during which a “base” rate of 10% would be paid, excluding China. In response, China’s retaliation brought US-China trade to a breaking point by 2025. The trade war between the two countries has been gradually reassessed, especially after Trump’s second term
- Trump is using tariffs as a negotiating tool. For example, he has criticized China’s role in the supply of fentanyl and imposed a 125% tariff as a leverage. He also aims to strain European industry (e.g. the automotive sector in Germany) by increasing transatlantic tensions with the EU.

Development Processes of Tariffs
January-February 2025
- On January 20, 2025, Trump ordered the preparation of reports on trade policies in a sales order.
- On February 1, Canada announced tariffs against Mexico and China.
- A 10% tariff on China was announced.
March-April 2025
- On March 4, Trump raised tariffs on China from 10% to 20%
- On March 10, China imposed a 15% tariff on US imports of chicken, wheat, corn and cotton, and a 10% tariff on soybeans, pork, beef, aquatic products, fruits, vegetables and dairy products in response to Trump’s 20% tariff. It also suspended imports of timber from the US and revoked soybean import licenses of three US firms.
- On April 2, Trump imposed a base tariff of 10% worldwide and said that a high proportion of trade deficits were “reciprocal tariffs”.
- An additional 34% in tariffs were added to China, bringing the total tariffs to 54%
- On April 9, Trump suspended the rates offered by others for 90 days, but raised tariffs on China to 104%.
- In response to Trump’s 104% tariff, China raised its tariffs to 84% on April 10.
- On April 11, China raised tariffs to 125% and added trade restrictions on 18 US companies. It also increased restrictions such as soil yields. In addition, travel warnings were issued to the US and restrictions were placed on the import of American films.
- Tariffs on China were raised to 145%, but some electronic products such as smartphones and computers retained this ability. This exemption was interpreted as an effort to ease inflationary pressure in the US.
- A “de minimis” exemption will be applied to products under $800, which applies to Chinese goods.
- (“De minimis” exemption is a term meaning “little things” and refers to the exemption of imported goods below a certain value from customs duties and certain procedures in international trade. In 2016, the US Congress raised the value limit of this exemption from USD 200 to USD 800, so that goods worth up to USD 800 per person per day shipment are exempt from duties and detailed customs procedures). This exemption expires on May 2nd. These goods will be subject to a 90% duty, or $75 per item, which will rise to $150 per item after June 1.
- US Treasury Secretary (Scott Bessent) stated that he expects the escalation of the trade war to stop and that the current situation is unsustainable
- On April 17, Trump announced: “We will make a deal with China”.
- On April 22, Trump said that he would be “very gentle” in negotiations with Beijing and that tariffs would fall if there was a deal, but not to “zero”.
- On April 23, Trump said: “Tariffs on China could come in the next 2-3 weeks”. The White House then said it was considering lowering tariffs on China to reduce the trade war.
- On April 24, Donald Trump announced a meeting with China, but no meeting took place
- On April 25, China said that, unlike the US, there had been no talks on tariffs and that “the US should stop creating confusion.”
- Donald Trump responded by saying: “Another tariff delay is unlikely.

Market Impacts

- The yield on the 2-year Treasury bond fell to 3.72%. The 10-year yield fell to 4.05%.
- Trump’s return to the White House in January 2025 caused a loss of $760 billion in cryptocurrency market value

Conclusion
As one of the negative consequences, tariffs could lead to price hikes for consumers and trigger global trade wars. For example, the Yale University Budget Lab estimates that a 20% tariff could cost US households an additional USD 3,400 per year.
Tariffs aim to stimulate production in the US. A 25% tariff on the automotive sector aims to increase production in American factories. On the other hand, this situation carries the risk of causing inflation by increasing costs. The tariffs are expected to push up the prices of imported goods as companies pass on some or all of their increased costs. Affected products could include everything from clothing to coffee, alcohol to electronics. Some firms may also decide to import fewer foreign goods, making existing ones more expensive. The price of goods made in the US using imported components could also increase. For example, car parts typically cross the borders of the US, Mexico and Canada several times before a vehicle is fully assembled. Car prices were expected to increase due to previous tariffs already in place. According to analysts at the Anderson Economic Group, the cost of a car manufactured using only parts from Mexico and Canada could increase by $4,000 to $10,000, depending on the vehicle.
According to the Tax Foundation, in 2025 these tariffs would increase federal revenue by USD 171.6 billion, but reduce long-term US GDP by 0.2%. Trump is trying to use the tariffs to reduce the trade deficit, revitalize production in the US and encourage China to the negotiating table. He also sees this policy as a source of revenue to finance his regulatory tax cuts. Trade between the two countries could fall by 80%, which could lead to a serious underperformance of the global economy. Neither side is backing down. Therefore, a short-term solution is not expected. In sum, Trump aims to change the global financial architecture with tariffs and strengthen the US position in international trade.
