Seasonal Headwinds Loom Large for Crude Oil Traders
As the year winds down, crude oil traders face seasonal headwinds that can impact prices. The Environmental Protection Agency (EPA) requires lower-volatility gasoline during the summer ozone season, which begins on May 1 for refiners and terminals, and June 1 for retailers. This transition to winter-grade gasoline, along with the end of the peak summer driving season, reduces demand for crude oil used by refiners.
Historically, this has led to lower prices during the fourth quarter. In fact, data from the U.S. Energy Information Administration (EIA) shows that Gulf Coast commercial crude inventories have declined from November to December in 13 of 14 years between 2012 and 2025, averaging a decline of about 8.9 million barrels.
However, geopolitical risk in the Middle East could produce sudden rallies, making disciplined risk management essential for traders. The region remains critical to global petroleum supplies, and unexpected military escalation or production disruption could quickly alter the supply-and-demand outlook.
