Brent crude futures fell 1.42% to US$89.45 a barrel, while U.S. West Texas Intermediate (WTI) slipped 0.66% to US$83.90. Both contracts had surged nearly 8% in the previous session on escalating Iran-related fighting. Shipping data showed 39 commodity vessels entered the Red Sea via the Bab el-Mandeb strait on Tuesday, the highest since July 19, while only a few transited the Strait of Hormuz. The traffic suggested key routes were not severely disrupted, easing near-term concerns over supply interruptions.
