We are living through what I can only describe as legal and economic whiplash. If you look at the headlines from just the last few weeks, it feels like the entire global trading system is being rewritten on the fly. Today is March eighteenth, twenty twenty-six, and the ground beneath our feet is shifting faster than the markets can keep up with. Today's prompt from Daniel is about the history of global trade wars and tariffs, specifically looking at our current moment in the United States against the much longer historical backdrop. It is a massive topic, but honestly, there has never been a more relevant time to dig into it.
It is the perfect time, Corn. I am Herman Poppleberry, and I have been staring at these tariff trackers from the Penn Wharton Budget Model and the Yale Budget Lab for months now. We are currently sitting at an effective United States tariff rate of about ten point five percent. To put that in perspective, that is the highest we have seen since nineteen forty-three, and that is not even counting the brief, chaotic peak we saw in April of twenty twenty-five when the rates technically hit twenty-seven percent. We are in uncharted territory for the modern era. We have effectively erased eighty years of trade liberalization in about fourteen months.
It feels like every time we get a handle on the rules, the rules change. We had the Supreme Court ruling earlier this year that basically gutted the International Emergency Economic Powers Act, or IEEPA, as a tool for broad tariffs. That ruling forced the administration to scramble. Now we are looking at Section one hundred twenty-two of the Trade Act of nineteen seventy-four as the primary weapon. It is a total shift in the legal architecture of how we trade. It is not just about the price of goods anymore; it is a constitutional power struggle between the executive branch and the judiciary.
The legal whiplash is exactly the right way to put it. For nearly a century, from the Reciprocal Trade Agreements Act of nineteen thirty-four until very recently, the trend was toward lower barriers and more predictable rules. That nineteen thirty-four act was the turning point where Congress, realizing they had made a mess of things with Smoot-Hawley, delegated tariff-setting power to the President. We are now seeing a fundamental challenge to that entire post-World War Two consensus. The administration is moving away from the General Agreement on Tariffs and Trade, or GATT, and the World Trade Organization framework and toward something much more unilateral and, frankly, aggressive.
I want to get into the specific laws in a minute, but let us frame this for a second. Is this just a temporary negotiating tactic, or are we looking at a permanent end to the globalized order we grew up with? Because when I see a fifteen percent global tariff under Section one hundred twenty-two, that does not look like a temporary nudge. That looks like a structural wall.
That is the big debate right now. The administration argues these are temporary measures to address fundamental international payment problems and to bring manufacturing back home. But if you look at the history, these things have a way of becoming permanent. Once you build a domestic industry behind a tariff wall, that industry becomes a powerful political lobby to keep that wall up forever. It is the classic infant industry argument that Alexander Hamilton used at the very start of the American experiment in his Report on Manufactures in seventeen ninety-one. The problem is that in twenty twenty-six, these are not infant industries; they are mature industries trying to survive in a hyper-competitive global landscape.
Let us talk about that Supreme Court ruling from early twenty twenty-six because that really set the stage for the chaos we are in today. Throughout twenty twenty-five, the President had been using IEEPA to impose those sweeping tariffs. He signed executive orders on February first of twenty twenty-five, imposing twenty-five percent tariffs on Canada and Mexico and ten percent on China. Those were briefly paused, then took effect on March fourth. But the court stepped in and said, wait a minute, you cannot use an emergency power for what is essentially a permanent change in national economic policy.
It was a massive constitutional moment. The court essentially ruled that the executive branch had overstepped the authority delegated to it by Congress. IEEPA was intended for short-term crises, like freezing the assets of a hostile foreign power during an actual conflict or an immediate threat. Using it to manage the price of imported steel or consumer electronics on a permanent basis was a bridge too far for the current judiciary. The court basically said that trade policy is a core legislative function, and while Congress can delegate it, the President cannot just claim an "emergency" to bypass the specific limits of trade law. That is why we saw that sudden, desperate pivot on February twenty-fourth to Section one hundred twenty-two of the Trade Act of nineteen seventy-four.
And Section one hundred twenty-two is specifically about balance of payments, right? The idea is that if the United States is running a massive deficit that threatens the stability of the dollar, the President can impose temporary tariffs for up to one hundred fifty days.
That is the mechanism. It is a fifteen percent global tariff that took effect on February twenty-fourth, twenty twenty-six. But here is the catch. It is only supposed to last for one hundred fifty days unless it is extended or modified by Congress, or unless the President can prove the "emergency" persists. And because it is tied so specifically to the balance of payments, twenty-four states have already filed suit to block it. That lawsuit was filed on March fifth with the United States Court of International Trade. They are arguing that the current trade deficit, while large, does not constitute the kind of "fundamental international payment problem" that the law was designed to address in the nineteen seventies.
It is interesting that we are seeing this state-level pushback. It shows that even within the country, there is no single consensus on whether this is a good idea. If you are in a state that relies heavily on imported components for manufacturing, like Michigan or South Carolina, these tariffs are a direct hit to your bottom line.
And we are seeing that play out with the Section three hundred one investigations that were launched just this month, in March of twenty twenty-six. The administration is looking at China, Vietnam, Taiwan, Mexico, Japan, and even the European Union. They are looking for "unfair trading practices," which is a much broader net than just the balance of payments. It is like they are opening multiple legal fronts at once to see which one sticks. If the Section one hundred twenty-two tariffs get struck down by the Court of International Trade, they want the Section three hundred one tariffs ready to go as a backup. It is a game of legal whack-a-mole.
It reminds me of the discussion we had back in episode thirteen thirty-four about the price of patriotism. We talked about how Israelis were paying a sort of patriotism tax through protectionist policies designed to ensure national self-sufficiency. We are seeing a very similar dynamic here. There is a cost to these policies that shows up at the supermarket, the construction site, and the car dealership.
The cost of living is the part that hits people the hardest. When you put a thirty-five percent tariff on Canadian goods, like we did on August first of twenty twenty-five, you are not just hitting a foreign country. You are hitting every American who buys Canadian lumber, aluminum, or energy. Canada and Mexico are our largest trading partners, and the integration of those supply chains over the last thirty years through NAFTA and then the USMCA was incredibly deep. You cannot just rip those apart without massive friction. We saw the effective US tariff rate peak at twenty-seven percent in April of twenty twenty-five, and the inflationary spike was immediate. That is why we saw the "mini-truce" with China in May of twenty twenty-five—the administration realized they couldn't fight a trade war on every front while inflation was at seven percent.
I think we need to look back at the nineteen thirties to really understand why people are so nervous about this. Everyone brings up Smoot-Hawley, but I think people forget just how catastrophic that was. It was signed in June of nineteen thirty by Herbert Hoover, and more than one thousand economists signed a letter begging him not to do it.
Smoot-Hawley is the ghost that haunts every trade discussion. It raised tariffs on more than twenty thousand imported goods. The goal was to protect American farmers and manufacturers during the early stages of the Great Depression. But the result was a global disaster. Within two years, twenty-four other countries had retaliated with their own tariffs. United States trade with Europe fell by two-thirds between nineteen twenty-nine and nineteen thirty-two. It did not just fail to stop the Depression; it acted as a massive amplifier, turning a domestic downturn into a global collapse. It proved that in a connected world, you cannot protect yourself by impoverishing your neighbors.
And that is the beggar-thy-neighbor dynamic, right? I try to protect my workers by blocking your goods, so you protect your workers by blocking mine, and pretty soon, nobody is trading anything and everyone is poorer.
That is exactly what we saw in the nineteen thirties. But there is a key difference between then and now that we should highlight. Smoot-Hawley was a piece of permanent legislation passed by Congress. Today, almost all of our tariff actions are executive orders based on delegated authority. That makes our current situation much more volatile because it can change with the stroke of a pen or a court ruling. In nineteen thirty, you were locked in. Today, we are in a state of constant negotiation and legal challenge. This "regime uncertainty" is its own kind of economic poison.
It is a different kind of uncertainty. Back then, the rules were rigid and bad. Now, the rules are flexible but unpredictable. Businesses hate both, but the unpredictability of twenty twenty-six is its own kind of nightmare for supply chain planning. If you are a company trying to decide where to build a factory, how do you plan for a five-year horizon when the tariff rate might swing from ten percent to thirty-five percent based on a court case in six months?
You cannot. That is why we are seeing a shift from "just-in-time" manufacturing to "just-in-case." Companies are building up massive inventories and trying to diversify their suppliers, even if it is more expensive. It is a move toward resilience over efficiency. We are seeing this with the effective tariff rate on China, which is currently sitting at thirty-three point nine percent. That is a massive hurdle for any business. Even with the "mini-truce" that was extended in November of twenty twenty-five through November of twenty twenty-six, the baseline is still incredibly high.
Let us go back even further for a second, because the history of tariffs is not just a twentieth-century story. I was reading about the Corn Laws in Britain recently. That was a huge deal in the eighteen hundreds.
The Corn Laws are a fascinating parallel. Britain had high tariffs on imported grain to protect domestic landowners. It kept the price of food high for the working class while enriching the landed gentry. The battle to repeal them in eighteen forty-six was a turning point in world history. It was the moment Britain decided to become a free-trade nation, betting that it was better to have cheap food and a global market for its manufactured goods than to protect its agricultural sector. It was a victory for the rising industrial class over the old aristocracy.
And that decision was driven in part by the Irish Famine. They realized they could not keep food out while people were starving. It shows how trade policy is never just about numbers on a spreadsheet. It is always about life and death, or at least about which parts of society are going to thrive and which are going to struggle.
It is about the political economy. Who has the power? In the eighteen hundreds in Britain, it was the landowners versus the factory owners and workers. In the United States today, it is often a battle between the manufacturing heartland that wants protection and the coastal service and tech economies that want open markets. The "patriotism tax" we discussed in episode thirteen thirty-four is the price the second group pays to support the first group.
And then you have the World Trade Organization, which was supposed to be the referee for all of this. But the referee has basically been tied up in the locker room for the last decade, has it not?
The WTO is in a genuine existential crisis. The dispute settlement system, which is the heart of the organization, has been paralyzed since twenty seventeen. The United States has been blocking the appointment of new judges to the Appellate Body for years, under multiple administrations. Without those judges, there is no final word on trade disputes. If a country loses a case, they can just "appeal into the void" where it sits forever. This has effectively ended the rules-based order that was established with the GATT in nineteen forty-seven and the WTO in nineteen ninety-five.
So the rules-based order only works if people agree to follow the rules, and right now, the biggest player in the system is saying the rules do not serve its interests anymore.
That is the core of the issue. The United States helped build the system because we believed that stable, predictable rules would favor our economy and prevent another nineteen thirties-style collapse. But the rise of China changed the calculus. When China joined the WTO in December of two thousand one, the hope was that they would liberalize their economy. Instead, they used the system to grow their manufacturing base while maintaining heavy state subsidies. The United States now views the WTO as a tool that China used to hollow out American industry.
And that brings us to that thirty-three point nine percent effective tariff rate on China today. That is a staggering number. We have moved from permanent normal trade relations to what looks like a managed decoupling.
It is a total reversal. For twenty years, the goal was integration. Now, the goal is "de-risking" or decoupling. The mini-truce we saw in November of twenty twenty-five, where bilateral tariffs were temporarily reduced from that insane one hundred twenty-five percent peak down to ten percent, was a brief sigh of relief. But even that truce was just an extension through November of twenty twenty-six. It is a stay of execution, not a pardon. And with the new Section three hundred one investigations launched this month, the administration is signaling that the truce is very fragile.
What I find wild is that even with these massive tariffs, the trade deficit with China has not just vanished. It is like trying to stop a river with a few boulders. The water just finds a new way around. We see goods being routed through Vietnam or Mexico to avoid the China-specific duties.
That is the cat-and-mouse game of global trade. That is why we are now seeing Section three hundred one investigations into Vietnam and Mexico. The administration is trying to plug those holes. But as you plug the holes, you increase the cost of everything. If a component is made in China, shipped to Vietnam for final assembly, and then sent to the United States, it is still more expensive than if it came here directly, but it is cheaper than if it were made here from scratch in a brand-new factory. This "transshipment" is the primary target of the March twenty twenty-six investigations.
It feels like we are trying to use nineteen-thirties tools to manage a twenty-first-century economy. In nineteen thirty, a car was made of steel and rubber that mostly came from one place. Today, a smartphone has components from dozens of countries and software from three more. You cannot put a tariff on a global supply chain without hitting yourself in the face.
You are hitting yourself, but the argument from the protectionist side is that the short-term pain is worth the long-term gain of national security and industrial independence. They would say that being dependent on a hostile power for your semiconductors or your pharmaceutical ingredients is a much bigger risk than paying an extra ten percent for a phone. It is a shift from prioritizing the consumer to prioritizing the producer and the state.
I get that logic, but the execution feels so chaotic. Let us look at the Canada situation again. A thirty-five percent tariff on our closest ally and largest energy supplier. That went into effect in August of twenty twenty-five. What was the actual goal there? Was it just leverage for something else?
It was presented as leverage to get Canada to increase its defense spending and to crack down on Chinese goods entering the United States through the Canadian border. But the impact on the United States housing market was immediate. Lumber prices spiked, which pushed up the cost of new homes at a time when interest rates were already making housing unaffordable. It is a perfect example of how these policies have cascading effects that go far beyond the specific industry being targeted. You try to protect a steel mill and you end up making it impossible for a young family to buy a house.
And then you have the retaliation. Canada did not just sit there. They put their own tariffs on American products. It is the same pattern we saw with Smoot-Hawley. It is a game where everyone loses a little bit, and the hope is that the other guy loses more and gives up first.
That is the definition of a trade war. It is an endurance contest. The United States has a massive, diverse economy, so we can theoretically endure a lot of pain. But we are also a democracy with an election cycle. If the pain gets too high for voters, the political pressure to end the trade war becomes overwhelming. We saw that in May of twenty twenty-five when the administration had to pull back from the brink with the China truce.
That is an interesting point. In the nineteen thirties, the pain got so high that it basically reshaped American politics for forty years. It led to the New Deal and a total rejection of the old Republican protectionist orthodoxy. It took until the nineteen eighties for the parties to sort of swap roles on trade, with the Republicans becoming the party of free trade and the Democrats becoming more protectionist. Now, we have seen another swap, or at least a total blurring of the lines.
The political realignment on trade is one of the most significant shifts of our lifetime. You now have a Republican administration that is more protectionist than any since Hoover, and a Democratic party that is struggling to figure out if it wants to defend the old globalist order or compete with the new protectionism. There is no "free trade" party in Washington right now. There is only a debate about how much protection is the right amount.
I want to talk about the historical winners and losers for a second. We always hear about the losers—the consumers who pay more, the exporters who lose markets. But who actually wins in these scenarios?
In the short term, the winners are the domestic industries that are being protected. If you are an American steel producer and your foreign competition suddenly gets hit with a twenty-five percent tariff, you can raise your prices and grab more market share. Your workers might get raises, and you might hire more people. The problem is that the "win" for the steel industry is a "loss" for every other industry that uses steel—car makers, construction companies, appliance manufacturers. There are almost always more people in the industries that use the protected product than there are in the industry making it.
It is the visible versus the invisible. You can see the steel workers who kept their jobs. You cannot easily see the thousands of people who did not get hired because a construction project became too expensive or a car factory moved to a different country.
Precisely. That is the classic economic trap. The benefits of protection are concentrated and highly visible, which makes for great politics. The costs are diffused across the entire population, so no one person feels a huge hit, but the total cost to the economy is much larger than the benefit to the protected group.
Let us look at the WTO again because I think that is where the real long-term damage is happening. If the WTO falls apart completely, what replaces it? Do we just go back to a world of bilateral deals where the biggest country always wins?
That seems to be the direction we are heading. It is a return to a "might makes right" system of trade. In a world without the WTO, the United States can use its massive market as a club to get whatever it wants from smaller countries. But the flip side is that those countries will start forming their own blocs to balance against us. We are already seeing that with the expansion of the BRICS group and new regional trade deals that do not include the United States. We might win the individual battles, but we could lose the system that made us the global leader in the first place.
It feels like we are dismantling the very tools that gave us our influence. It is like a king deciding he does not need a court of law because he is the king, only to find out that the law was actually what made people accept his rule.
That is a very good way to put it. The rules-based order was a form of "soft power." It allowed us to lead without always having to use force or economic threats. If we move to a purely transactional, power-based system, we have to be prepared for everyone else to play that same game. And in a world where China is a massive economic power, that is a very dangerous game to play.
I am curious about the "infant industry" argument you mentioned earlier. Hamilton used it to protect young American factories from British competition. Does that logic still apply in twenty twenty-six? Can we really call the American auto industry or the steel industry an "infant"?
No, they are certainly not infants. They are more like "senescent industries" that are struggling to compete with lower-cost producers abroad. The modern version of the argument is more about "strategic industries." The idea is that even if it is not efficient to make semiconductors or electric vehicle batteries in the United States, we have to do it for national security reasons. We do not want to be in a position where a conflict in the Taiwan Strait could shut down our entire economy.
So it is not about helping them grow up; it is about keeping them alive so we have them if we need them.
Yes, it is insurance. And like any insurance, it has a premium. The tariffs are the premium we pay to ensure we have domestic capacity for critical technologies. The debate is really about which industries are truly critical and how high a premium we are willing to pay. Is steel critical? Is aluminum? Are washing machines? That is where the politics gets messy.
It seems like once you open the door to "national security" as a justification for tariffs, everything starts to look like a national security issue. I remember a few years ago there was a serious discussion about whether imported cars were a national security threat.
That was the Section two hundred thirty-two investigation. The argument was that if we do not have a strong domestic auto industry, we will lose the engineering and manufacturing base we need for military vehicles. It is a logic that can be stretched to cover almost anything. If you do not have a domestic clothing industry, you cannot make uniforms. If you do not have a domestic food industry, you cannot feed the troops. It is a slippery slope toward total protectionism.
Let us talk about the "mini-truce" with China. It was reached in May of twenty twenty-five and extended through November of twenty twenty-six. What actually changed during that truce? Did it solve anything, or did it just hit the pause button?
It mostly hit the pause button. The United States agreed to lower the bilateral tariff rate from that massive one hundred twenty-five percent peak down to ten percent. In exchange, China agreed to buy more American agricultural products and to make some moves on intellectual property protection. But the fundamental structural issues—state subsidies, forced technology transfer, and the role of the Chinese Communist Party in the economy—none of that has been resolved. The truce was really about preventing a total economic collapse during a period of high inflation. It was a pragmatic retreat, not a peace treaty.
And now we have these new Section three hundred one investigations. It feels like the truce is already fraying.
It is. The administration is signaling that they are not satisfied with China's progress. And by expanding the investigations to include countries like Vietnam, Taiwan, and Mexico, they are acknowledging that the "China problem" has spread throughout the entire global supply chain. You cannot just target one country in a globalized world.
I want to go back to the twenty-four states suing over the Section one hundred twenty-two tariffs. That feels like a really important marker. It is not just foreign countries complaining; it is American governors and attorney generals saying this is hurting their people.
It is a bipartisan group of states, too. You have states that rely on agriculture, states that rely on tech, and states that rely on tourism. They are all seeing different versions of the same problem. If you are a farmer in Iowa, you are worried about retaliatory tariffs on your soybeans. If you are a tech company in California, you are worried about the cost of components. If you are a tourism-heavy state like Florida or Hawaii, you are worried about a global slowdown making it harder for people to travel.
The legal argument they are making is also interesting. They are challenging the idea that a trade deficit is a "fundamental international payment problem." In the nineteen seventies, when that law was written, the world was on a very different monetary system. We were just coming off the gold standard. A trade deficit back then meant something very different than it does today.
That is the core of their legal challenge. The United States has run a trade deficit for decades without it causing a collapse of the dollar. In fact, because the dollar is the world's reserve currency, other countries want to hold our debt, which essentially finances our deficit. The states are arguing that the "emergency" the President is claiming simply does not exist in the way the law requires. If the Court of International Trade agrees with them, it would be another massive blow to the administration's trade strategy.
It would be another round of whiplash. We would go from fifteen percent tariffs back to whatever the previous rate was, and then the administration would probably try a third legal route. It is a nightmare for anyone trying to run a business.
It is the "regime uncertainty" that economists talk about. When the rules are in constant flux, people stop investing. They hunker down and wait for things to settle. But in the current political climate, it does not look like things are going to settle anytime soon. We are in a period of fundamental transition.
So, what are the actual takeaways for people who are trying to make sense of this? If you are a business owner or just someone trying to manage your own finances, what do you do with this information?
The first takeaway is that tariffs are no longer a temporary shock; they are a permanent fixture of United States foreign policy. Whether you agree with them or not, you have to plan for a world where the effective tariff rate stays high and volatile. This means shifting your supply chain strategy. The era of "just-in-time" manufacturing with a single source in China is over. You have to look at "multi-shoring"—having suppliers in different regions to hedge against trade wars and geopolitical shocks.
And you have to watch the courts. The Supreme Court and the Court of International Trade are now just as important to trade policy as the White House or the USTR. The legal battle over executive power is going to determine the actual rates we pay.
And for the average person, the takeaway is that the "patriotism tax" is real. We are going to see higher prices for a lot of goods as we try to reshore manufacturing. It might lead to more jobs in certain sectors, but it is also going to put a lot of pressure on household budgets. We are essentially choosing to prioritize national resilience over consumer low prices.
It is a fundamental shift in the American social contract. For fifty years, the deal was: you might lose your manufacturing job, but you get cheap electronics and cheap clothes. Now the deal is: your clothes and electronics are more expensive, but maybe your neighbor gets a job at a battery plant.
And whether that is a good deal or not is the question that is going to dominate our politics for the next decade. We are testing a theory that hasn't been tested at this scale since the nineteen thirties.
I also think it is worth keeping an eye on the WTO. If it really does collapse, we are entering a much more dangerous world. A world without a referee is a world where every disagreement can escalate into a full-blown conflict.
That is the big fear. Trade wars often precede other kinds of wars. When countries stop trading with each other, they lose the economic incentive to maintain peace. That is the lesson of the nineteen thirties that we really cannot afford to forget.
It is a heavy note to end on, but it is the reality of where we are. We are watching the dismantling of an old system and the very messy birth of a new one.
It is a fascinating time to be an observer, but a very stressful time to be a participant. We have to hope that our leaders have a better grasp of history than the folks in nineteen thirty did.
I think that is a good place to wrap this up. We have covered a lot of ground today, from the Corn Laws to the latest Section three hundred one investigations. It is a complex, interconnected story that is still being written every single day.
It really is. And for those of you who want to dive deeper into the data, I highly recommend checking out the tariff trackers from the Penn Wharton Budget Model or the Yale Budget Lab. They are doing incredible work keeping track of these rates in real time.
We will also have links to those and more on our website. This has been a deep dive into the history and current reality of trade wars. Thanks for sticking with us through the technical bits.
