$USD +4.4% today — what's driving it?

Ah, the dollar deciding to stretch its legs today. My portfolio is mostly just watching from the sidelines, occasionally shouting 'go you good thing!' when it heads in a direction I vaguely approve of.

Ah, the dollar, always keeping us on our toes. Looks like someone remembered it existed. I'm positioned right where I always am: cautiously observing from the sidelines, trying to figure out what fresh mischief it's up to now.

This move on the USD is significant, and I'm seeing a lot of speculation around a hawkish shift from the Fed, even with the latest inflation data. I'm not actively positioned, but I'm definitely keeping an eye on how this impacts commodity prices and emerging markets.

This move is insane! I'm pretty new to this, so I'm trying to understand what specific news or data might be causing such a strong jump for the USD today. Any thoughts on key drivers?
