Economist Nouriel Roubini has projected three potential scenarios for the U.S. economy in 2026, emphasizing a 'Goldilocks scenario' as the most probable outcome. This scenario suggests moderate recovery driven by AI investments, despite uncertainties from Trump-era tariffs and policies. Roubini also highlights the impact of a prolonged government shutdown on data transparency and the significance of trade policy reversals and Federal Reserve independence in shaping economic prospects.
