2026年美国经济展望：乐观预期背后的三个风险

Group 1: Core Viewpoint - The 2026 economic outlook for the U.S. is optimistic, with expectations of growth exceeding 2%, driven by AI investments, tax reforms, and continued interest rate cuts by the Federal Reserve [1][6][7] Group 2: Optimistic Factors - AI investment is expected to continue expanding, contributing to GDP growth, although the growth rate may significantly decline compared to previous years [1][6] - The "Big and Beautiful" tax reform has already been implemented in 2025, with limited incremental policies in 2026, leading to a potential decrease in fiscal stimulus effects [1][6] - The Federal Reserve plans to cut interest rates only twice in 2026, maintaining a neutral policy rate around 3%, which may provide some economic relief but not strong stimulus [1][6] Group 3: Risks - The negative impact of tariffs is expected to persist, with the effective tariff rate reaching its highest since 1943, potentially reducing long-term economic growth by 0.7 percentage points and contributing to inflationary pressures [2][7] - The labor market is projected to remain weak, with high unemployment rates and low job growth, which may constrain consumer spending and income growth [2][7] - Stock market returns may decline due to uncertainties related to AI narratives, monetary policy, and midterm elections, leading to a weakened wealth effect that could suppress consumption and investment [2][8]
