Mont Belvieu — the wholesale benchmark
Mont Belvieu, Texas hosts the largest US propane storage and trading hub. The Mont Belvieu propane spot price is the underlying wholesale benchmark for the US market — quoted in cents per gallon, it trades continuously on commodity markets. The EIA publishes daily Mont Belvieu prices.
From wholesale to retail
Three layers sit between Mont Belvieu and your tank:
- Midstream transport and storage — rail, pipelines, regional terminals
- Local dealer operations — terminal-to-depot trucking, on-site storage, customer service
- Bobtail delivery — truck delivery to your tank
Each layer adds cost. The total retail markup over wholesale typically sits at \$1.50–\$2.00 per gallon for residential customers. So a $1.00/gal wholesale price typically implies $2.50–$3.00/gal retail.
Wholesale price volatility
Mont Belvieu spot is correlated with crude oil but not identical to it. NGL fundamentals (natural-gas processing economics), export demand, and US shale production rates all move propane independent of crude. Wholesale prices can swing 30–50% within a year while retail prices smooth somewhat due to dealer hedging and contract terms.
Why retail is stickier than wholesale
Retail prices don't move daily with wholesale because dealers hedge — they hold inventory at known costs, offer pre-buy contracts that lock rates, and smooth pricing to customers across delivery cycles. A wholesale spike of $0.50/gal might translate to a $0.20/gal retail increase over several weeks, not immediately.
FAQ
Where is Mont Belvieu?
Mont Belvieu is a small town in Chambers County, Texas, about 35 miles east of Houston. It sits atop one of the largest natural underground salt-dome storage formations in the US, used for storing propane, ethane, butane and other NGLs.
Is propane price tied to oil?
Loosely. Propane is a byproduct of both crude refining and natural-gas processing. Crude oil prices set the general direction, but NGL fundamentals (gas-processing economics, export demand) drive propane-specific movements that diverge from crude.
