Flint Hills Resources announced this week that they have increased posted prices, effective Monday, June 25. Their 100 grade increased by 5 cents per gallon, the 70 grade increased by 9 cents per gallon, and the 75, 230 and 600 grades by 10 cents per gallon. No other moves have been announced at this time, and the market was otherwise largely unchanged since last week.

Some buyers are reporting that certain Group I grades, primarily the heavier grades, are tightly balanced, while some length continues in the lighter Group II grades. This situation may further explain some of the interest in the recent arbitrage development, at the same time that some Group II producers have expressed interest in providing supply to Europe and elsewhere, where there is relatively little current Group II production. In view of the fact that some domestic Group I producers report adequate supply, the imbalances may be regional in nature rather than affecting the market everywhere equally.
