A critical wildcard is the Supreme Court's pending review of Trump's broad tariff policiesDonald Trump - Wikipedia^[1]. If upheld, these tariffs could accelerate inflationary pressures and trigger retaliatory measures from trading partners, creating near-term turbulence for export-heavy industries.
