Oil prices fell as investors weighed the outlook for Russian diesel supplies against the Saudi-Houthi conflict, with Brent crude down 1.48% to $105.05.

Oil prices fell on Tuesday as investors weighed the possibility of more Russian energy entering global markets, while concerns about the Saudi-Houthi conflict limited losses. Brent crude futures fell 1.48% to $105.05 per barrel, and U.S. West Texas Intermediate crude futures fell 1.57% to $92.27 per barrel. Donald Trump on Monday defended his administration's decision to temporarily ease restrictions on Russian diesel supplies, despite warnings from U.S. lawmakers that the move could weaken sanctions against Russia. Goldman Sachs' analysis suggests that additional Russian diesel supplies are unlikely to significantly alleviate global fuel price pressures, expecting that an incremental 800,000 tons (approximately 6 million barrels) would only reduce wholesale diesel prices by $1 to $2 per barrel in the U.S. Gulf Coast and Europe. Goldman Sachs noted that Russian refinery outages have led to a 3 million barrels per day reduction in output compared to the same period last year, limiting its ability to increase production. Yemen's Houthi rebels attacked King Khalid International Airport in Riyadh, the capital of Saudi Arabia, on Saturday, killing 12 people and injuring more than 300, in a significant escalation of the conflict.
