During the first half of January 2026, the Diisopropyl Ether (DIPE) Del USGC prices started the year on a bearish tone, falling by 4.17% during the first week due to relatively weaker feedstock fundamentals and stable import flow. Isopropyl Alcohol is down by 0.39% while the production cost is trimming as the propylene prices are slipping down. Domestic production and DIPE imports from Germany and Japan poured in supply, keeping the Gulf Coast stocks replenished. End-use demand for DIPE was not pressing in the post-holiday period as solvent formulators and fuel blenders held off buying. The second week ended with prices stable, representing a divergence from the weakening 12-week short-term bearish trend, and this was the case because there had been very subdued changes on the DIPE supply/demand.
