On the 9th, Brent crude futures fell 4.7%, and WTI also dropped 4%.

Brent crude futures fell about 4.7% to $93.71 a barrel on the 9th, while WTI dropped roughly 4% to $87.38, according to figures cited by Crypto Briefing and converted at 1,361 won per dollar. The report also said Brent lost 16% over the prior week, a steeper decline than the roughly 12% intraday estimate published six days earlier before trading closed. The two Brent declines reflect different points in the session and should not be added together as a single-day move. The selloff matters as a sharp repricing of oil benchmarks, and the next thing to watch is the final settlement price, since the quoted levels are not closing prices.
