The Trump administration is set to announce a new wave of sanctions against Iran, dubbed “economic D-Day,” which are expected to significantly impact global oil and gas prices. These sanctions follow and exacerbate existing trade tensions, particularly with Canada. Experts predict the measures will further strain international trade relations and potentially disrupt energy markets. The administration anticipates the economic pressure will force Iran to renegotiate its nuclear agreement. Concerns are rising about the potential for increased costs for American consumers at the gas pump and beyond. NBC News is reporting on the unfolding situation and its anticipated effects on the U.S. economy.
