Rep. Brian Fitzpatrick (R-Pa.) plans bipartisan legislation to block U.S. purchases of Russian oil, including diesel. Energy markets reacted with heating oil futures dropping 4.33% on Friday. Refining stocks like PBF Energy (PBF), Marathon Petroleum (MPC), and Valero Energy (VLO) fell. Trump authorized Russian diesel imports for six months, raising legal and political concerns. Analysts question the impact on prices and criticize the move as a short-term solution.

President Trump announced Russia will supply 4.8M tons of diesel to global markets, including the U.S., following a call with Putin. Heating oil futures dropped 4.33% on the news. Shares of refiners like MPC, PBF, and VLO declined. The deal reverses recent U.S. sanctions on Russia, with the Treasury issuing a temporary license for trade.

Shares of Valero Energy (VLO), Marathon Petroleum (MPC), Sunoco (SUN), and Phillips 66 (PSX) rose overnight after President Trump's executive order allowed temporary highway use of dyed diesel and deferred federal fuel tax. The move aims to lower fuel costs amid rising energy prices. VLO gained 0.67%, MPC 0.35%, SUN 3%, and PSX 1%. Analysts note limited impact on diesel prices due to state regulations and global supply issues.
