Although the relationship between futures market prices and retail prices is not immediate and one-for-one, the most recent trend in futures prices suggests that gasoline and diesel retail prices will ease moderately in the coming week.

Gasoline prices have been volatile in many local markets. The upward trend began with increasing crude oil prices. Localized price hikes have been accentuated by the switch to summer grades, refinery issues, and flooding in the Midwest, which has disrupted ethanol supply and transportation. The current weakening of crude prices should slow the upward trend of gasoline prices.
