If tariff rates continue to rise beyond revenue-maximizing thresholds, then domestic consumption costs increase while external trade flows contract, reducing fiscal returns even as protectionist claims intensify.
There is a moment—often missed in real time—when a tariff stops being a shield and becomes a tax on national prosperity. In 1765, the British Stamp Act and associated trade duties were designed to replenish imperial coffers after war, but they crossed a fiscal threshold where revenue potential gave way to rebellion and loss. In 1930, the Smoot-Hawley Tariff, intended to protect American farmers, instead triggered global trade contraction and reduced U.S. tariff income by over 60% within three years [Irwin, 1998]. Now, in 2026, we see a new empire of consumption—the United States—leaning on tariffs not just for leverage, but for balance sheet relief. The Pujolas and Rossbach study provides empirical confirmation: 20% of U.S. tariffs are now on the wrong side of the Laffer Curve, yielding less revenue with each increase. This is not just an economic miscalculation; it is a symptom of a deeper cycle where fiscal desperation transforms protection into self-sabotage. The pattern is clear: when a nation starts optimizing tariffs for revenue rather than resilience, the decline has already begun.
