Key Points
- The U.S. has introduced new tariffs, including a 10% baseline on all imports and higher rates for specific countries.
- Investors are concerned, with the key stock market indices all down over 3%.
- Historical instances, such as the Smoot-Hawley Tariff, suggest that high tariffs can exacerbate economic downturns. 
President Donald Trump’s announcement of sweeping tariffs has sent shockwaves through global financial markets.
The introduction of a baseline 10% tariff on all imports, with higher rates for specific countries, such as a 34% tariff on Chinese goods and a 25% levy on automobile imports, has led to significant market volatility and raised concerns about long-term economic growth.
Investors are concerned about future economic growth - which is a key driver of the stock market. The new tariffs will make goods more expensive, likely reducing consumer spending. Any gains from the tariffs to U.S. manufacturing could take upwards of a decade to materialize.
More frustrating to investors is that the calculation of the tariffs seems misguided. Trade deficits themselves are not bad, and arbitrary tariffs don't necessarily serve a purpose.
Understanding The New Tariffs And Their Calculation
The administration’s tariff strategy aims to address trade imbalances by imposing taxes on imported goods.
The tariffs are calculated based on the trade deficit with each country: the U.S. goods trade deficit with a nation is divided by the total goods imports from that country, then halved.
For example, with China, a $295 billion trade deficit divided by $440 billion in imports results in approximately 67%, halved to a 34% tariff. This method targets countries with which the U.S. has significant trade deficits, aiming to reduce these imbalances by making imported goods more expensive and encouraging domestic consumption.
However, it's important to remember that trade deficits aren't necessarily bad. The United States is the largest economy in the world, and there's no scenario where it would be able to produce everything it wants and needs domestically. Furthermore, there's even less of a possibility that it produces everything it wants and needs, and still could export goods.
Purchasing items from other countries is typically viewed as a positive, even if a country can't sell back product in exchange. For example, Switzerland (which Trump is imposing a 61% tariff on goods), is a small country of only 8 million people. The United States buys products from them, including chocolate, watches, and more. However, even in the best scenario, there's not way that Switzerland could buy enough product from the United States to offset the imbalance. It's not possible.
The net result is that Americans will pay more, and likely buy less. This will hurt both countries, but America more in the long term - as Switzerland's industries can simply sell to other countries worldwide.
Historical Context: Lessons From Past Tariffs
The U.S. has previously implemented high tariffs, notably the Smoot-Hawley Tariff Act of 1930, which imposed substantial duties on imports. This act led to international retaliation, reduced global trade, and is widely believed to have worsened the Great Depression.
The current tariff measures echo these past policies, raising concerns about repeating historical economic downturns. It's important to remember that tariffs are paid by the importer, not the company who makes the product. That importer, in turn, will raise the price to offset the tariff. So, a grocery store might import beans from Mexico, and they'll have to raise their prices in the store to offset the new, higher price.
Tariffs can serve a specific purpose: they protect domestic industries from foreign competition. If you make foreign products more expensive (via tax), it can incentivize domestic industries to be competitive.
However, domestic industries cannot ramp up quickly. For example, bringing car manufacturing back to the United States would take decades. Car markers cannot simply build new factories in months - that takes years. That's also assuming they have the money to do so. If their car sales fall due to higher prices, they may be in bad financial shape and still lose the battle to foreign car makers.
Conclusion
The implementation of these tariffs represents a significant shift in U.S. trade policy, with immediate impacts on financial markets and potential long-term economic consequences. The stock market is down over 3% as a result, adding to an already rough start to the year.
