IEA: Oil Supply Jumps to 105.4M Barrels a Day, Diesel Stays Pricy

There's plenty of crude sloshing around the world. The International Energy Agency pegs global oil supply at 105.4 million barrels per day in October, a surge that would normally spell cheaper fuel. Diesel didn't get the message.

The bottleneck sits in the refineries, not the oilfields. Refinery runs dropped to 81.3 million barrels per day, according to the IEA, and that constraint is blunting the pass-through from abundant crude to the diesel pump. MarketWatch flagged the gap between the two numbers as the reason prices are staying stubborn.

Europe is feeling it most. Diesel prices there remain roughly 77% above pre-war levels, even with crude supplies running hot. Refining capacity, not crude availability, is doing the damage.

Next up for traders: OPEC's production strategy and geopolitical flare-ups in the Middle East, both of which can swing global supply. The IEA's own updates on refinery output and demand forecasts are the other lever to watch, with the Energy Information Administration's supply and demand reports also on the radar.
