Dollar Dominance: The Fed's Geopolitical Shadow

Main Question: How does Fed monetary policy shape US geopolitical power, and what does the Powell-to-Warsh transition mean for dollar dominance?
Argument: The dollar's reserve status turns every Fed decision into a geopolitical event, enabling financial sanctions while keeping BRICS alternatives marginal.
Conclusion: Warsh's hawkish instincts can reinforce dollar credibility, but ultimately, his goal is not to push US geopolitical objectives.
