The world’s diesel market is running out of time to replenish dangerously low fuel stockpiles before hurricane season and refinery maintenance kick in — a development that could ripple through inflation, trade, and supply chains. As Bloomberg reports, storage tanks from the U.S. Gulf Coast to Rotterdam and Singapore are only just beginning to recover from historic lows, and industry experts warn that any disruption now could have outsized consequences.
Despite every effort to boost output, the pressure remains high. Diesel — often referred to as the “workhorse fuel” of the global economy — powers everything from trucks and trains to farm equipment and home heating. And as U.S. inventories hover near 20-year summer lows, concerns are mounting that the market is still vulnerable to sharp supply shocks.
“We’re bullish for the end of the year,” said Rami Ramadan, co-head of global middle distillates at BB Energy, in comments to Bloomberg. “We are going to be in for some shocks for sure because of how Europe has been disconnected from its closest sources of supply.”
That disconnection was worsened when the European Union banned direct diesel imports from Russia. The continent now depends on cargoes from much farther afield — particularly Asia and the Middle East — and this shift has significantly increased price volatility. Recent disruptions, such as the temporary halt of Israeli gas flows to Egypt after tensions with Iran, have only reinforced global energy market fragility.
Meanwhile, former U.S. President Donald Trump’s proposed tariffs on India — a key processor of Russian crude into diesel — could further strain supply chains and hit European markets particularly hard. At home, Trump’s broader trade war agenda risks raising domestic costs at a time when U.S. farmers are bracing for peak diesel demand during fall harvest.
“The fate of the fuel has wide-reaching ramifications for the global economy,” Bloomberg notes, with elevated diesel prices already trickling into consumer inflation and squeezing business margins. American drivers are now paying the highest prices at the pump in about a year.
Even with major refiners like Valero and Phillips 66 ramping up diesel production, the global picture remains tight. “Heading into hurricane season, if we have some type of supply disruption, I think you’ll see a pretty significant market reaction with inventories as low as they are,” said Gary Simmons, Valero’s Chief Operating Officer, during a recent earnings call.
In Europe, diesel is trading at a premium of more than $20 a barrel above Brent crude — a spread known as the “crack” — while in the U.S., it’s closer to $30. Pre-Ukraine war, this premium seldom exceeded $15. Goldman Sachs forecasts this structural tightness to persist through at least 2026, and energy major TotalEnergies has called strong diesel prices a “persistent feature” of the current energy landscape.
Additional pressure is coming from jet fuel demand, which has surged alongside a recovering aviation sector, and concerns that a cold winter could strain heating oil supplies — all middle distillates drawn from the same refining stream.
Still, not everyone is betting on a diesel squeeze. Recent weeks have brought some relief, with increased fuel shipments from Asia and the Middle East. Data from Kpler shows July saw the highest volume of diesel and jet fuel cargoes heading to Europe in 11 months. Supertankers carrying up to two million barrels are currently en route, according to shipping sources.
Brian Mandell, Executive Vice President at Phillips 66, acknowledged these flows and said he’s closely monitoring export dynamics from the Middle East and India. While he believes distillate margins will stay strong through the end of the year, he expects eventual relief as OPEC+ brings more heavy crude — ideal for diesel production — back online.
But that process takes time: “It takes a while to go from targets to actual production, and then for the barrels to be shipped, processed into diesel, and finally reach the fuel’s buyers,” Mandell said.
