Tariffs & Free Trade by Wade
June 2, 2025 at 2:24 pm
Tariffs and trade have dominated the media headlines since the beginning of the year, creating a volatile rollercoaster ride in the financial markets and broader economy. What were screams of fear just last month turned into cheers of optimism after a trade deal between the U.S. and the U.K. was announced earlier this month.
This agreement—combined with hopes for future trade deals and the absence of runaway inflation or economic collapse—sparked a rally in stock prices. The minimum 10% baseline tariff in the U.K. agreement has fueled optimism that a simplified framework might extend to other international trade pacts. For the month, the S&P 500 surged by +6.2%, the Dow Jones Industrial Average climbed +3.9%, and the tech-heavy NASDAQ soared by +9.6%.
However, tariffs and trade haven’t faded into the background. In fact, just this week, a federal court ruled that the president’s tariff policies were illegal, citing misuse of emergency powers under the International Emergency Economic Powers Act (IEEPA) of 1977. Subsequently, the same court has granted the Trump administration a reprieve pending appeal—potentially escalating the issue to the Supreme Court. Even if the ruling stands, the president has alternative avenues to impose tariffs through other legal mechanisms.
So, what is all this fuss over tariffs and trade really about? I’ve previously written extensively on the topic (“Tariff Sheriff”), but some fundamental economic concepts still get lost in the tariff chaos noise.
It’s true that many countries engage in unfair trade practices against the U.S.—including subsidies, currency manipulation, non-tariff barriers, dumping, quotas, complex permitting, and value-added taxes (VAT). However, the powerful benefits of free trade are often underappreciated or poorly explained by the pundits.
Tariffs and Free Trade 101: China & France Experiment
To illustrate, let’s reference an example drawn from an op-ed by Princeton economist Burton Malkiel, author of the legendary finance book A Random Walk Down Wall Street.
Every country enjoys a comparative advantage in producing certain goods. For example, China historically benefits from low labor costs, making it a global manufacturing hub. Meanwhile, the U.S. leads in technological innovation, and countries like Brazil leverage vast land resources to dominate agricultural exports—such as being the world’s top coffee exporter. Let’s consider a simplified example using two countries: China and France, each with 100 labor hours available, and only able to produce T-shirts and wine.
China’s Output (see graphic above) – China’s comparative advantage in making more T-shirts than bottles of wine results in the following:
- 50 hours = 50 T-shirts
- 50 hours = 10 bottles of wine
France’s Output (see graphic above) – France’s comparative advantage in making more bottles of wine than T-shirts results in the following:
- 50 hours = 50 bottles of wine
- 50 hours = 20 T-shirts
Combined Total (China + France): 70 T-shirts + 60 bottles of wine = 130 total units of goods.
Example #2: Production Plan #2 (Each country specializes in their comparative advantage)
China’s Output (T-shirt specialization):
France’s Output (Wine specialization):
- 100 hours = 100 bottles of wine
Combined Total: 100 T-shirts + 100 bottles of wine = 200 total units of goods.
But here’s the challenge: the Chinese still want wine, and the French still want T-shirts. That’s where free trade comes in – see next example (graphic below).
Example #3: Production Plan #2 + Free Trade
Through free trade, each country can specialize in what they do best and then trade for other goods wanted or needed. If China trades 50 T-shirts for 50 bottles of wine with France, both countries end up with:
- China: 50 T-shirts + 50 bottles of wine
- France: 50 bottles of wine + 50 T-shirts
This plan produces 54% more total goods than the original production plan (200 vs. 130 – Example #1), with no increase in labor hours. China gets 300% more wine, and France gets 150% more T-shirts—a clear win-win.
Today’s Tariff Reality
In 2024, the U.S. trade deficit stood at $918 billion. President Trump’s aggressive tariff strategy aims to reduce this gap by incentivizing domestic manufacturing, increasing exports, and reducing imports. The challenge is that tariffs also raise prices for consumers and disrupt the benefits of free trade.
If the administration succeeds in establishing fairer rules for a level trading field, increasing government revenue, and narrowing the trade deficit, then history will likely view President Trump’s tariff policy favorably. But if tariffs lead to higher prices, inflation, and a weaker economy, the tariff policy may be judged as a costly misstep. The stock market, voters, and time will ultimately serve as the principal judges.
Looking ahead, two key dates are on the calendar:
- July 9 marks the end of the 90-day reciprocal tariff pause. Without new trade agreements, tariffs will spike on imports from many countries — raising costs for consumers.
- July 4 is not only Independence Day, but also the target date for Senate Republicans to pass the “One Big Beautiful Bill”, which packages several of President Trump’s top priorities: tax cuts, welfare reform, energy expansion, and border security. While the bill could stimulate growth, critics warn of its potential to balloon the national deficit.
Most Americans support the idea of fairer global trade. The question is whether aggressive tariffs across the globe are the right tool to achieve that goal — and whether trading partners will agree to new deals. Regardless of the outcome, this crash course in Tariffs & Free Trade 101 underscores the enduring value of specialization and free trade, even amid today’s turbulent tariff battles.
