What Is a Basis Spread?
A basis spread (or basis differential) is the price difference between the same commodity at two different locations. It measures the cost of moving energy from one hub to another — reflecting transportation, pipeline capacity, and regional supply/demand.
Key Basis Spreads in Energy Markets
| Spread | What It Measures | Typical Range |
|---|---|---|
| Waha-Henry Hub | Permian Basin pipeline bottleneck severity | -$10 to +$1/MMBtu |
| Brent-WTI | Atlantic Basin crude oil arbitrage window | -$3 to +$10/bbl |
| Brent-Dubai | East-West crude flow economics | $0 to +$8/bbl |
| TTF-Henry Hub | Atlantic LNG export incentive | $2 to +$30/MMBtu |
| Brent-Oman | Physical delivery premium signal | -$2 to +$5/bbl |
The Waha Paradox: When Gas Prices Go Negative
The Waha Hub in West Texas is the primary trading point for Permian Basin natural gas. In 2026, Waha experienced 44 consecutive days of negative pricing — producers literally paid others to take their gas.
This happens because:
- Associated gas — Permian gas is a byproduct of oil drilling. Producers can't stop gas production without stopping lucrative oil production.
- Pipeline bottlenecks — Production (27.7 Bcf/d) overwhelms takeaway capacity to the Gulf Coast.
- No storage — Unlike oil, stranded gas has limited local storage options.
The Waha-Henry Hub basis spread quantifies this bottleneck. When it's deeply negative (-$7 to -$10), it signals severe infrastructure constraints. New pipelines like Matterhorn Express and Hugh Brinson are expected to normalize this by late 2026.
Brent-WTI: The Global Crude Arbitrage
The Brent-WTI spread reflects the relative value of international vs domestic U.S. crude. When Brent trades at a premium to WTI, it incentivizes U.S. crude exports. When the spread narrows or inverts, domestic supply is tight.
Why Basis Spreads Matter
For midstream companies: Basis spreads determine whether pipelines are economically full. A wide Waha-HH basis justifies new pipeline investment.
For traders: Basis differentials create arbitrage opportunities. If you can move gas from Waha to Henry Hub cheaper than the basis spread, you profit.
For producers: Basis risk is the risk that the price at your production location diverges from the benchmark. Permian producers face massive basis risk on gas.
