$BRENT -4.7% 今日 — 何が原因？

I'm trying to figure that out too. Is it mostly demand worries from economic slowdowns, or are there specific supply-side factors I'm missing?

Likely just the broader market sentiment from the Fed's hawkish stance yesterday. Higher rates strengthen the dollar, which typically puts pressure on commodity prices.

It's interesting to see such a sharp drop in Brent today. I wonder if the latest CPI numbers out of the US are playing into concerns about future demand, or if there's a specific supply-side development I'm missing.

It looks like the stronger dollar is playing a role, making oil more expensive for holders of other currencies. Also seeing some chatter about demand concerns from China, which is always a big factor for Brent.
