How Costco sells such cheap gas
Costco said on its quarterly earnings call that demand for gas has surged, with some stations needing tanker trucks multiple times daily to avoid running dry. CEO Roland Vachris attributed strong traffic to low prices, which typically undercut local stations by about 30 cents/gal. Costco said gas margins are thin but membership fees drive profit; gas added ~0.1 percentage point to gross margin in 2024 when prices were under $3, but subtracted 0.2 points last quarter.
Gas pricing dynamics are pressuring Costco’s gross margin but appear to be boosting member traffic and warehouse sales.
Costco reported on its earnings call that gas demand surged, with tanker truck support and higher loyalty spending tied to gas pricing.
Near-term: sentiment likely mixed—margin headwind from low gas prices vs. loyalty/traffic tailwind from high prices.
Background
Costco’s fuel business is typically low-margin, but it can influence store traffic and basket size via its membership model.
Why it matters
The key trading takeaway is regime dependence: high gas prices increase volume and loyalty but squeeze overall margin because fuel remains a low-margin product; low gas prices do the reverse.
Market relevance
Earnings-call commentary links gas-price levels to both margin impact and member loyalty, explaining a negative stock reaction despite traffic gains.
Market effects
Highlights how retailers with membership/scale can use low-margin fuel to drive higher-margin basket sales, affecting retail-gas competitive framing.
West Coast gas prices above $6 are cited as a driver of demand and member behavior, implying regional sensitivity to fuel price swings.
Limited; story is US-centric and tied to Costco’s US station footprint and membership model.
Alternative perspectives
If gas prices fall, Costco’s gas margin headwind may be offset by sustained loyalty and continued higher warehouse spend from members who learned to shop around fuel visits.
The article doesn’t quantify how much incremental warehouse spend offsets gross-margin changes from fuel; also, line congestion could dampen future conversion if gas remains cheap.
