Social Security COLA May Hit 4.2% in 2027 on Iran War Energy Spike

The Social Security cost-of-living adjustment (COLA) for 2027 is now forecast to rise as much as 4.2%, according to updated projections, as surging gasoline and energy prices—driven by the ongoing Iran conflict—push inflation higher.

The COLA is calculated based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), with energy costs playing an outsized role. The Iran war has disrupted oil supplies from the Middle East, sending crude prices sharply higher and lifting retail gasoline prices. This directly feeds into the CPI-W, boosting the COLA forecast. For energy traders, the link between geopolitical risk and inflation expectations is a key driver of crude futures and refined product spreads. Traders can monitor real-time gasoline and crude prices on NowPrice's live fuel dashboard to track these moves.

Looking ahead, the actual COLA will be announced in October 2026, based on third-quarter CPI-W data. Traders should watch weekly EIA inventory reports and any developments in Iran-related supply disruptions, as these will influence energy prices and, consequently, the final COLA figure. A sustained energy price rally could push the adjustment even higher, while a de-escalation might temper the forecast.
