美元镰刀，这样挥向全球

Core Viewpoint - The relationship between the strength of the US dollar and geopolitical conflicts is not coincidental, as the dollar's fluctuations are often influenced by the US's strategic use of its financial power in conjunction with military and political maneuvers [1][11]. Group 1: Dollar Strength and Geopolitical Events - The dollar is expected to face significant pressure in 2025 due to internal fiscal deficits and high policy uncertainty, coinciding with a series of geopolitical conflicts from East Asia to the Middle East [2][30]. - Historical patterns show that periods of dollar strength often align with heightened geopolitical tensions, suggesting a strategic use of crises to bolster the dollar's appeal [4][10]. - The dollar's strong performance during crises, such as the 9/11 attacks and the Ukraine crisis, illustrates how external conflicts can drive capital back to the US, reinforcing its status as a safe haven [8][10][25]. Group 2: Mechanisms of Dollar Support - The dollar's strength is supported by a combination of risk premium dynamics, where geopolitical crises trigger a flight to safety, leading to increased demand for dollar-denominated assets [17][19]. - The US's military alliances and geopolitical strategies create a network of financial dependencies among its allies, further solidifying the dollar's position as the preferred reserve currency [22][23]. - The concept of "petrodollars" emphasizes the necessity of maintaining the dollar's dominance in global oil trade, with military and political actions taken to protect this status [25][26]. Group 3: Future Implications and Challenges - The current geopolitical landscape suggests that the mechanisms supporting the dollar may face diminishing returns, as global markets become desensitized to frequent crises [54][56]. - The potential for a shift towards a multipolar currency system is increasing, as countries seek to diversify away from reliance on the dollar, driven by security concerns and economic independence [57][58]. - The ongoing geopolitical tensions may lead to a more complex and volatile dollar trajectory, characterized by sharp fluctuations rather than a smooth decline [55][56].
