The US Dollar Index climbed to 101.80 on June 24, marking a 13-month high and its strongest level since May 2025. The culprit, or hero depending on your portfolio, is a tidal wave of global capital rushing into American AI assets.
Since late January 2026, when the DXY sat at 95.55, the dollar has gained more than 5%. That kind of move in the world’s reserve currency isn’t just a forex story. It’s a gravitational force that pulls on every asset class, and crypto is feeling it more than most.
The AI magnet effect

US private AI investment hit $109.1 billion in 2024, vastly outpacing every other country on the planet. That figure has only accelerated into 2026, with hyperscaler capital expenditures continuing to climb as companies race to build out data center capacity.
