年中展望 | 美国“例外论”的终结（申万宏观·赵伟团队）

Core Viewpoint - The article discusses the shift in global macroeconomic narratives from "American exceptionalism" to "American denialism," driven by factors such as tariff impacts, fiscal constraints, and the implications of the "One Big Beautiful Bill Act" [2][8]. Group 1: Narrative Shift - The global macroeconomic narrative has transitioned from "American exceptionalism" to "American denialism" in the first half of 2025, influenced by tariff disruptions and trade conflicts [3][8]. - In early 2025, the S&P Global Manufacturing PMI remained above the neutral mark for three consecutive months, indicating resilience in industrial production, but fell below 50 in April [2][8]. - The IMF revised its global GDP growth forecast for 2025 down to 2.8%, with the U.S. forecast reduced from 2.7% to 1.8% [2][23]. Group 2: Economic Contradictions - The economic impact of tariffs has become a central theme, with the focus shifting to macro data validation rather than negotiation processes [4][53]. - The average tariff rate in the U.S. surged from 2.4% at the end of 2024 to approximately 16% by May 2025, marking a significant increase [4][54]. - The "One Big Beautiful Bill Act" primarily extends existing tax cuts, which may have limited economic stimulation effects but could increase long-term debt supply pressure [4][84]. Group 3: Paradigm Shift in Asset Safety - The current economic baseline for the U.S. is a slowdown without recession, with inflationary pressures expected to persist for 2-3 quarters [5][8]. - The article suggests that if the dollar and U.S. Treasury bonds no longer serve as "safe assets," it could challenge the high valuations of U.S. tech stocks and the sustainability of twin deficits [6][8]. - The transition from "American exceptionalism" to "American denialism" raises questions about the long-term viability of U.S. assets in the global market [6][8].
