The Court Said No. The President Said 10%.
On February 20, the Supreme Court ruled 6–3 in Learning Resources, Inc. v. Trump that the International Emergency Economic Powers Act does not authorize the president to impose tariffs. Chief Justice Roberts wrote that IEEPA "does not mention tariffs, duties, taxes, or similar terms," and that the Constitution vests the taxing power in Congress alone. The ruling invalidated tariffs that had raised over $160 billion in revenue.
Hours later, President Trump signed a proclamation under Section 122 of the Trade Act of 1974, imposing a 10% "temporary import surcharge" on goods from all countries, effective February 24. Within days, he announced his intention to raise it to 15%. Section 122 caps unilateral surcharges at 150 days without congressional approval.
The stakes: whether the executive branch can sustain a global tariff regime without congressional authorization — and whether a 150-day window is enough to force trade concessions from allies and adversaries alike.
Power sits with: the White House and its willingness to test legal boundaries.
Risk falls on: importers, consumers, and the roughly 2,000 businesses already seeking refunds from the invalidated IEEPA tariffs.
Nixon's 10% Surcharge and the End of Bretton Woods (1971)
On August 15, 1971, President Richard Nixon announced a 10% import surcharge on all goods entering the United States — part of a broader package (the "Nixon Shock") that also closed the gold window, ending the dollar's convertibility to gold and effectively killing the Bretton Woods monetary system.
The surcharge was not primarily about trade. It was a weapon of coercion. The dollar was overvalued, American manufacturers were losing competitiveness, and the U.S. had just posted its first trade deficit since the 19th century. Nixon's Treasury Secretary John Connally told foreign finance ministers bluntly: the dollar is "our currency, but it's your problem."
The surcharge was designed to force America's trading partners — particularly Japan, West Germany, and France — to agree to revalue their currencies upward. It worked in the short term. The Dow posted its largest single-day gain in history. Nixon's approval ratings climbed. By December, the Smithsonian Agreement delivered the currency realignment Nixon wanted, and the surcharge was lifted after roughly four months.
But the long-term consequences were severe. The Bretton Woods system never recovered. Floating exchange rates brought volatility. Inflationary pressure from a devalued dollar, combined with the oil shock of 1973, produced the stagflation that defined the decade. The 10% surcharge was described at the time as the first general tariff increase since Smoot-Hawley. It was "temporary." It reshaped the global financial architecture permanently.
The institutional pattern: a president bypassing legislative channels, using emergency-adjacent authority to impose a blanket tariff as leverage, enjoying immediate political gains, and setting in motion second-order consequences no one fully priced in.
Where the Pattern Holds — and Where It Breaks
- Both presidents imposed a 10% blanket import surcharge using executive authority after conventional policy channels were blocked or exhausted.
- Both used the tariff as a coercive negotiating tool rather than a long-term revenue instrument — designed to force trading partners to make concessions.
- Both followed a period of rising trade deficits and domestic political pressure around manufacturing competitiveness.
- Both enjoyed immediate political support, with markets and opponents initially uncertain how to respond.
- Both operated under a ticking clock — Nixon's surcharge lasted ~4 months; Trump's Section 122 authority caps at 150 days without Congress.
- Nixon acted proactively to reshape the monetary system. Trump acted reactively, hours after the Supreme Court invalidated his preferred mechanism — making this as much a constitutional confrontation as a trade maneuver.
- In 1971, trade was ~5% of U.S. GDP. Today it is ~25%. The same percentage tariff hits a much larger share of the economy.
- Nixon had bipartisan congressional support and broad institutional cooperation. Trump faces a divided Congress, an adversarial judiciary, and multiple governance frictions simultaneously.
How Strong Is This Echo?
Incentive alignment is near-perfect. The structural constraint — a 150-day hard clock with an adversarial judiciary — has no clean 1971 parallel, and the blast radius of a tariff is five times larger today.
Incentive alignment scores maximum — both presidents used a blunt tariff instrument to extract foreign concessions while satisfying a domestic political constituency. Economic conditions rhyme: trade deficits, manufacturing anxiety, a dollar under pressure. Public psychology matches — broad initial support with latent inflation fears. Institutional similarity loses a point because Nixon had Congress behind him, while Trump faces active judicial opposition. The wildcard penalty applies because the Supreme Court ruling introduces a constitutional dimension that has no parallel in 1971.
The Blind Spots of 1971
Most observers in August 1971 treated the surcharge as a short-term negotiating tactic — which it was. What they missed was that the tactic's success would make the larger systemic damage politically invisible until it was too late to reverse.
Nixon got his currency realignment within four months. The surcharge was dropped. Victory declared. But the Bretton Woods system, which had provided monetary stability since 1944, was fatally wounded. No one in the administration had a plan for what would replace it. The floating exchange rate regime that emerged was not designed — it defaulted into existence because the old system couldn't be reassembled.
The deeper incentive failure: Nixon's team optimized for the negotiation, not the system. Connally's job was to win the immediate confrontation with foreign finance ministers. He did. But no one was tasked with modeling the second-order effects of a devalued dollar combined with expansionary fiscal policy. The result — stagflation — was the predictable consequence of incentives no one was tracking.
Conventional wisdom in 1971 held that the surcharge would discipline trading partners and restore American competitiveness. It did neither. What it actually did was transfer the costs of monetary adjustment to consumers and future administrations.
Three Paths from Here
The 150-day window works as intended leverage. Major trading partners agree to bilateral concessions within 90 days. The surcharge is reduced or lifted before expiration. Markets stabilize. The administration claims victory. Underlying trade imbalances remain unresolved, but the political cycle moves on. This is the Nixon 1971 playbook executing as designed.

Trading partners refuse to negotiate under duress. Trump pushes the surcharge to 15% and pressures Congress for statutory authority to extend beyond 150 days. Retaliatory tariffs hit U.S. agricultural exports and tech components. Consumer prices rise visibly. GDP growth dips further.
The Section 122 surcharge faces a second legal challenge. A second adverse court ruling forces an open confrontation with the judiciary over trade authority. Congress is drawn in to either codify or block executive tariff power. Markets price in sustained policy uncertainty. Capital flight from dollar-denominated assets accelerates.

The Number That Matters
Trade as a share of U.S. GDP in the Smoot-Hawley era versus today. When Nixon imposed his 10% surcharge in 1971, trade was roughly 11% of GDP — already double Smoot-Hawley's era. Today's 25% means the blast radius of a blanket tariff is structurally larger than any historical precedent. The same tariff rate now hits five times more of the economy.
