US Energy Information Administration data for the week to 18 September showed gasoline inventories fell by 1.686 million barrels. Markets had been looking for no change, with expectations at 0 million.
The report implies a larger draw than forecast over the period, marking a deviation from the consensus view of flat stock levels. The EIA figure places the weekly move at -1.686 million barrels versus a 0 million-barrel expectation.
Resilient Demand and Inventory Implications
We see the unexpected 1.686 million barrel draw in US gasoline stocks as a clear signal of resilient late-summer demand. This sharp decline, compared to the market’s expectation of flat inventories, suggests that the typical post-Labor Day demand slump is not as severe as anticipated. Derivative traders should prepare for short-term upward pressure on RBOB gasoline futures in the coming weeks as a result.
Historically, US refineries begin their seasonal maintenance in late September as they transition to cheaper winter-grade gasoline, which routinely reduces utilization rates from summer highs of over 93% down toward the high 80s. With refining capacity already tightening, this supply draw means we are entering the maintenance season with much thinner inventory cushions than usual. We recommend looking at long-call options on October gasoline contracts to capitalize on this impending supply squeeze.
Trading Strategies and Risk Management
We also suggest that traders monitor the gasoline crack spread, which measures the margin between crude oil and refined product prices. Given that gasoline is drawing down faster than crude, buying the RBOB-to-WTI crack spread could offer a high-probability trade over the next two to three weeks. This strategy allows us to capture the relative strength of gasoline without taking on full exposure to broader macroeconomic oil shocks.
To manage risks, we must closely watch the weekly EIA demand figures, which historically average around 8.5 million barrels per day during late September. If demand holds above this average, the current bullish momentum for refined products will likely carry deep into October. We should set tight stop-losses just below the recent key support levels in RBOB futures to protect our positions against any sudden drop in consumer spending.
