Smart Protectionism

Protectionism is back. The 21st century has brought with China’s rise, European and Russian decline, U.S. manufacturing erosion, and vulnerabilities in global supply chains. Protectionist policy, previous discarded by the Washington Consensus, is once more on the forefront of economic thought. But its effectiveness depends on execution, scheduling, and sequencing to create coherent industrial policy.

President Trump’s tariff instincts are in the right place, but lack in depth planning. It is unclear whether his administrations views tariffs as an incentive of industrial policy or a diplomatic device. The optimal strategy differs even from department to department. While the Trump administration has taken the most pro tariff policy of any president since William McKinley, the implementation of these policies lack the economic nuance that American protectionism once boasted. Hamilton’s manufacturing theories, Lincoln’s self-sufficiency policy, and even Biden’s CHIPS act make Trump’s “plans” look immature by comparison.

Hamilton’s Report on Manufactures is one hundred pages and formed the foundation for the National System of American Economics. He reasoned that industrial policy could secure America’s economic independence, raise revenue, encourage infant industry, and create economies of scale. Lincoln argued that tariff revenue could secure funding for the infrastructure projects of the 19th century. Even Biden’s administration showed finesse by combining strategic tariffs with targeted subsidies for key industries like semiconductors and rare earth minerals. As these examples show, tariffs work best when viewed as tools for long-term industrial policy, not political hammers for temporary leverage.

First, if there is going to be a strong “tariff regime,” then the implementation and time scheduling of import duties need to be managed carefully. Tariffs are long term plans for reindustrialization, not Band-Aids. When Trump launched the Liberation Day tariffs in April, tariffs were raised across the board for every country in the world all at once. The result? Negative GDP growth in 2025’s first quarter from a surge in imports and the second worst day of the S&P 500 Index. The sudden and dramatic increase in import taxes caused panic and mass ordering of foreign goods while domestic products struggled.

Time scheduling is important for stability. “Optional spending” like large-scale investment can swing wildly, in contrast to consumer spending, which is more often a topic of political discussion, but also which is less subject to variance. Investment requires careful calculations over a few months at the least and several decades at the most. In the 21st century where a modern car can have over 40,000 parts, supply chains dominate logistical thinking. Even a small delay in supply can disrupt entire industries. Instead of sudden hikes on imports, the government should roll out tariffs on an incremental schedule which would last for several months or years. This type of strategy would cool the market, allow firms to make long term plans for reindustrialization, and retain stability while achieving the same goals. In the current, notoriously unpredictable administration, economic stability would be a welcome change for America’s industrial stakeholders.

Scheduling is important for administrative reasons as well. Poor scheduling can mean the court system, biased against Trump, can become involved, leading to months of delays and general confusion. Constant policy reversals cause economic distress since businesses, often investing in huge projects over many years, are thrown into disarray as politicians shift on policy that affects firms greatly.

A true protectionist policy would identify the key sectors needed in a modern economy and work to reshore them at home to spur innovation in other industries. Biden’s CHIPS act paired tariffs with subsidies to critical industries. A Republican parallel would not target countries but certain goods. Semiconductors, cars, shipbuilding are all urgently needed at home to build strategically significant industries. Protectionism works. The Trump administration needs to implement trade policies that make it work for Americans.
