S9 Ep6: What's next for Trump’s tariffs?

Episode Summary

Executive Summary: This episode examines Trump’s 2025 tariff campaign as a political and legal project rather than a conventional trade policy. Richard Baldwin argues “Liberation Day” marked a U.S. retreat from trade leadership and a shift toward coercive, symbolic economics, while Gene Grossman explains why the tariffs’ emergency legal basis is weak and likely to fail in court—though other tariff pathways remain available.

Main Topics: Liberation Day as a break with the global trade order (Priority: 5/5): Baldwin frames April 2, 2025 as the start of a war on trade, saying Trump’s tariff announcement shattered prior U.S. commitments to free trade and WTO leadership. Tariffs as political signaling, not economic policy (Priority: 5/5): Baldwin argues the tariffs are designed to appeal to a grievance-driven middle class and MAGA voters, with headline rates used for messaging while many imports are exempted to limit price effects. China’s retaliation as asymmetric precision pressure (Priority: 4/5): China’s export controls on rare earth magnets are presented as a more targeted and potentially more powerful response than U.S. tariff broadside, because permits can choke critical inputs without a full embargo. The legal challenge to the emergency tariff authority (Priority: 5/5): Grossman explains that the administration relied on a national-emergency declaration to seize tariff-setting power from Congress, but the claimed emergency—manufacturing decline and trade deficits—looks weak and longstanding. Supreme Court uncertainty and alternative tariff routes (Priority: 4/5): Grossman outlines that the case is now before the Supreme Court, with markets pricing in a likely loss for Trump, but notes alternative legal bases remain if this authority is struck down. The erosion of rules-based trade governance (Priority: 5/5): Both speakers stress that the larger consequence is damage to the WTO and to trust in U.S. commitments, making the institutional recovery harder than any single tariff rollback.

Key Arguments: Trump’s April 2 announcement was not just the start of a trade war but a broader assault on the postwar trade system and U.S. treaty credibility. The publicly advertised tariff rates overstate the actual impact because roughly half of U.S. imports are exempt, especially from Canada, Mexico, and parts of China trade. The policy is meant to generate political loyalty by portraying Trump as defending working Americans against global elites, rather than to optimize welfare or prices. China’s response through rare earth magnet export permits is strategically potent because it targets a critical industrial input and can be deployed without a full embargo. The emergency justification is legally fragile because manufacturing decline and trade deficits are long-running structural trends, not sudden extraordinary threats. Grossman expects the Supreme Court is likely to strike down the specific authorization used, but tariff pressure may persist via other statutes such as national security, balance-of-payments, or unfair-trade claims. Even if one legal route fails, tariffs are unlikely to disappear entirely because U.S. politics now broadly rewards blaming foreigners for economic pain. The biggest long-run casualty is the WTO-based rules system, which depends on voluntary trust and lacks enforcement power once the U.S. stops acting as steward.

Data Points: Date of Liberation Day announcement: 2 April 2025 - Trump announced reciprocal tariffs in the Rose Garden, launching the policy discussed in the episode. U.S. import exemption share: About 50% - Baldwin says roughly half of U.S. imports are exempted from the headline tariffs. China’s rare earth magnet share: 95% - China reportedly produces 95% of the world’s rare earth magnets, giving its export controls major leverage. Manufacturing employment decline window: 2000–2010 - Grossman says the major decline in manufacturing employment occurred during this decade, not recently. Trade deficit duration: 40–50 years - Grossman notes the U.S. trade deficit is longstanding and therefore not evidence of an emergency. Goods trade deficit surge claimed by administration: 40% in five years - Grossman says this figure is misleading because it is nominal and not adjusted for inflation or GDP. Inflation over the same period: 22% - Grossman says inflation explains much of the rise in the nominal goods trade deficit. Biggest trade deficit as share of GDP: 2006 - Grossman says the largest deficit relative to GDP occurred in 2006. Temporary authority window under an alternative law: 150 days - Grossman says one alternative tariff route based on balance-of-payments issues would only last 150 days. Market-implied probability of losing in court: 75% - Grossman cites betting markets that assign a 75% chance the tariffs will be struck down.

Pivotal Quotes: "April second was a historical event. I mean, people think that maybe it was the start of a trade war, but it wasn't. It was the start of a war on trade." — Richard Baldwin: Baldwin’s framing of Trump’s Liberation Day announcement and its significance for global trade. "The emergency, as it was declared, is that our manufacturing sector is in decline. We have a big trade deficit... this has all been going on for many, many years." — Gene Grossman: Grossman explains why the legal emergency basis for the tariffs is weak. "The biggest deficit as a share of GDP was back in 2006." — Gene Grossman: Grossman uses this to argue that the trade deficit is not an acute emergency.

Implications: The episode suggests tariffs may persist even if one legal basis fails, but the deeper risk is lasting damage to U.S. credibility and the WTO system. Firms, lawyers, and trading partners should expect prolonged uncertainty and policy volatility.
