North American oil companies delivered a striking second-quarter earnings season. Upstream producers raised output guidance while maintaining capital discipline, arguing that efficiency gains, not higher spending, are driving growth. Meanwhile, refiners benefited from some of the strongest margins since 2022, fueled by robust diesel and jet fuel demand, lower Chinese exports, refinery outages in Russia, and Middle East-related disruptions. Jeff Mower is joined by Janet McGurty and Ashok Dutta to unpack the key earnings themes shaping oil markets.

The Rhine River is one of Europe's most important trade arteries, carrying diesel, gasoil, and other refined products from the Amsterdam-Rotterdam-Antwerp hub to consumers across Germany, Switzerland, and beyond. As water levels fall toward historic lows, barges are carrying reduced loads, freight costs are surging, and supply chains are coming under increasing pressure. With Rhine water levels approaching record lows, Europe's energy industry faces mounting logistical challenges that threaten to disrupt the inland movement of fuel. In this episode, Emma Kettley, price reporting associate director, EMEA crude and fuel oil, joins Middle Distillate Price Reporters David Neef and Sophia Aung to explore how declining water levels are driving up freight costs, tightening supply chains, and adding fresh pressure to an already constrained diesel market.

Diesel prices have soared, driven by supply constraints through the Strait of Hormuz and by the ongoing war between Russia and Ukraine. Ukraine has been able to knock out a sizable percentage of Russia's refining capacity, shrinking global supplies.

Where does that leave Brazil, which has been dependent on diesel imports from Russia? How do Brazil's price subsidies impact diesel supplies? What role could India play in supplying diesel fuel? What policy options, if any, does the Trump administration have to solve the supply problem? Join Jeff Mower, S&P Global Energy's director of Americas oil news, as he dissects these topics with Aaron Tucker, managing editor of Americas middle distillates, and Renato Rostas, Brazil oil price manager.
