US President Trump says working very hard on Russia and Ukraine, adds the Ukraine war is the toughest war to end and is the one driving up diesel prices

The specific reference to diesel is notable; the conflict's clearest transmission channel into oil markets has run through distillates rather than crude itself, via disrupted Russian product flows, rerouted cargoes and elevated freight and insurance costs, which has kept diesel cracks structurally more sensitive to war headlines than Brent outright. Comments framing a deal as difficult read as a tempering of near-term ceasefire expectations rather than a breakthrough signal, and rhetoric of this sort has historically had limited durability in prices unless accompanied by concrete steps such as sanctions relief, enforcement changes, or a formal negotiation track. The actors' prior form matters: this administration has repeatedly floated imminent progress on the conflict without immediate follow-through, so the market has learned to discount language and wait for the operational detail. The tells worth noting are any movement on sanctions enforcement against Russian energy flows, shadow fleet measures, and scheduled contacts between the principals, since those are the levers that actually move distillate supply. As stated, this is colour on process, not a change in the supply picture.
