The Catalyst

President Trump’s tariff strategy responds to persistent U.S. trade deficits and perceived national security risks. The administration cites “hollowed-out manufacturing” and supply chain vulnerabilities as justification for these measures.

Inside Forces

The strategy combines:

  • IEEPA authority for broad 10% tariffs
  • Section 232 investigations for sector-specific taxes
  • Reciprocal tariffs targeting deficit countries

Power Dynamics

Trump leverages executive authority to bypass congressional approval, using:

  • National security justifications for Section 232
  • Economic emergency declarations under IEEPA
  • Bilateral negotiations for country-specific rates

Outside Impact

Tariffs have generated significant revenue but raised costs for businesses and consumers:

  • $108B collected in first nine months of 2025
  • 49% cost burden on U.S. consumers
  • 39% impact on domestic businesses

Future Forces

Key upcoming developments:

  • August 1: New reciprocal tariffs take effect
  • November 2025: Copper/lumber investigation conclusions
  • Ongoing negotiations with Mexico/Canada

Data Points

  • April 5: 10% baseline tariff implementation
  • April 3: 25% auto tariffs begin
  • July 7: Reciprocal tariff extension to August 1
  • August 1: 50% copper tariffs effective

This multi-layered tariff approach represents a strategic shift from broad trade wars to targeted economic interventions. While generating significant revenue, it risks escalating costs for domestic industries and consumers while testing international trade relationships.
