Crude oil futures fell back, with Brent crude slipping below the $100 per barrel level it had breached the previous day. The introduction of new tariff measures by US President Trump, seen as a headwind for the global economy, cooled the market. Brent futures dropped as much as 4.3% to $96.40. The day before, they had risen above $100 for the first time in about two months following an attack on a tanker in the Red Sea by Yemen's Iran-backed Houthi rebels. Tamas Varga, an analyst at PVM Oil Associates, noted that the market's focus has shifted to demand, with the new US import tariffs possibly being perceived as a path to global demand destruction. Despite the day's decline, Brent futures are still up about 10% for the week.
