Brent crude oil futures hovered above $67 per barrel on Wednesday, following a 3% gain in the previous session that lifted prices to an almost four-month high, driven by supply disruptions. A severe winter storm cut US crude production by up to 2 million barrels per day, about 15% of national output, and temporarily halted Gulf Coast exports, as energy infrastructure and power grids came under strain. Icy and wet conditions across parts of the South are expected to delay restarts. Traders are also keeping a close eye on the US military buildup in the Middle East and the heightened risk of potential action against Iran. Adding further support, API data showed US crude inventories fell by 0.25 million barrels last week, defying expectations for a 1.45 million-barrel build. Meanwhile, the US dollar slid to its lowest level in nearly four years, boosting the appeal of dollar-denominated commodities to buyers.
