避险情绪蔓延至主要外汇？

I'd lean more towards central bank divergence right now. The market is still trying to price in what the Fed, ECB, and BOJ are going to do next, and that's creating bigger swings than just general risk sentiment.

Good point on the USD strength. It's hard to separate the two entirely, but a strong dollar often correlates with a risk-off mood anyway, even if the primary driver is rate differentials.
