Episode notes
Supreme Court Reasserts Limits On Presidential Tariffs
- The Supreme Court ruling reaffirmed separation of powers by limiting presidential tariff authority under IEEPA/Section 122.
- Eswar Prasad warned this constrains the administration's ability to impose broad tariffs and injects legal and policy uncertainty for partners.
Hold Off Renegotiations Until Tariff Dust Settles
- Wait before renegotiating trade deals because the U.S. tariff landscape is unsettled and exemptions may change outcomes.
- Eswar Prasad advises countries that worsened under broad tariffs should request renegotiation or seek exemptions rather than rush back.
Tariff Uncertainty Comes From Time Limit And Global Scope
- Section 122 tariffs are temporary (150 days) and apply globally, creating two uncertainty dimensions: duration and universality.
- Torsten Slok noted markets and negotiators now face unknown timing and which countries/products are covered.
