US national average retail gasoline prices fell below $4 per gallon in the week of November 9, 2026, driven primarily by softer crude benchmarks—WTI near $85–88 per barrel and Brent around $92—as well as the seasonal switch to lower-cost winter-blend fuel and weakening autumn demand. Weekly EIA and API data showed rising gasoline and distillate inventories amid recovering refinery output post-maintenance, while lower heating oil and diesel consumption further eased pressure. These dynamics produced a roughly 20-cent weekly drop to approximately $3.90 by November 12, with RBOB wholesale prices declining faster than retail. Traders monitoring the market will watch the next EIA inventory release and any shifts in crude volatility tied to geopolitical developments or weather-driven demand forecasts.
