**[Bitunix Analyst: U.S.-Iran Negotiations Signal Energy Easing, But Diesel Crisis Makes Inflation Risks Harder to Resolve]** BlockBeats News, September 25 — Representatives from the U.S. and Iran engaged in discussions during the UN General Assembly regarding a phased ceasefire, proposing a plan to reopen the Strait of Hormuz within seven days in exchange for the U.S. easing economic sanctions. This marks the first time the market has seen diplomatic potential for restoring energy supplies. Following the news, international oil prices fell nearly 2% intraday, reflecting traders pricing in expectations of supply recovery after the strait's reopening. However, core disagreements remain over the strait's jurisdiction and the extent of sanctions relief, meaning diplomatic signals alone are insufficient to equate to actual supply recovery. More concerning is that energy risks have expanded from a single shipping route issue to the entire supply chain. Houthi forces launched six ballistic missiles at Saudi energy facilities in Yanbu and other locations, threatening the Red Sea export capacity originally intended to bypass the Strait of Hormuz. This implies that even if U.S.-Iran negotiations improve navigation expectations for Hormuz, the market will still demand higher risk premiums for Saudi alternative export capacity, Red Sea shipping, and the security of energy infrastructure. As a result, oil prices are simultaneously factoring in "diplomatic optimism" and "supply security risks." The U.S. diesel market reveals another layer of more challenging policy contradictions. Retail diesel prices have surged to a historic high of $6.51 per gallon, prompting the White House to consider restricting exports. However, U.S. maritime diesel exports in August already reached approximately 1.6 million barrels per day. If overseas demand is directly curtailed, Gulf Coast refineries may reduce operating rates due to inventory buildup and deteriorating profit margins, ultimately weakening the overall production of gasoline, diesel, and jet fuel. In other words, administrative restrictions can alter the flow of fuel but cannot directly create additional supply. Therefore, the key observation for the market on September 25 is not the short-term decline in oil prices but whether energy supplies can gradually recover from "multiple bottlenecks." If U.S.-Iran negotiations progress, Hormuz reopens, and risks to Red Sea and Saudi energy facilities decrease, supply shocks may genuinely ease. Conversely, if there is a time lag between diplomatic progress and actual supply recovery, costs for diesel, transportation, and agriculture may continue to exert inflationary pressure through secondary effects. This transforms energy policy from a simple issue of price management into a critical variable influencing global inflation and monetary policy space.
