Recent policy shifts could unravel decades of financial architecture. As one economist points out, the post-WWII system worked like this: America maintained open markets, secured trade routes, and provided military backing to key allies. In exchange, the US got something valuable—cheap access to global capital, steady foreign investment flows, and the dollar's unchallenged position as the world's reserve currency.

But here's the tension: what if that arrangement starts breaking down? If the US pulls back from its traditional role, other nations might stop funding American deficits quite so readily. They might diversify away from dollar holdings. That reshuffling could shake the very foundations of how global commerce operates. For crypto markets especially, this macro backdrop matters enormously—it directly affects fiat currency stability, cross-border capital flows, and the incentives driving institutional adoption of digital assets.
