Pyth Network Launches Six Constant Maturity Futures Indices for Energy Commodities

Traditional energy futures feeds expire on a fixed date. A September crude contract that represents a full 30-day view in late August becomes a near-expiry position by the end of the month, and any platform built on top of it must migrate to the October contract before that expiry arrives, absorbing the price discontinuity at the handover. Pyth Network PYTH$0.052-4.4% PYTH launched six constant maturity futures indices on September 15 to remove that migration cycle, according to the company.

How Constant Maturity Removes Roll Dates From WTI, Brent, and Gas Futures

A constant maturity index holds the time to expiry fixed rather than tracking a single contract toward zero. Pyth Network's implementation maintains a synthetic contract always expiring thirty days forward, achieved by continuously interpolating between the two listed contracts that bracket that point. Weighting shifts in real time as the contracts move; no discrete roll date exists. "The maturity never shrinks. There is no expiry to migrate away from," the company states.

The six indices cover West Texas Intermediate (WTI) crude, Brent crude, Henry Hub natural gas, Henry LD1 natural gas, London WTI, and Dutch TTF gas. All price in USD to five decimal places and update every 50 milliseconds during market hours.

Trading hours follow the underlying exchange calendars: approximately 23 hours daily, five days per week, with a one-hour maintenance window and a closure from Friday afternoon through Sunday evening. When underlying contracts stop trading, the indices pause with them.

Constant Maturity Futures vs Pyth's Always-On Spot Indices

These indices are distinct from the always-on commodity feeds Pyth launched earlier this year. When Pyth brought crude oil pricing on-chain with 24/7 WTI and Brent spot indices in June, that product used a constructed methodology to continue publishing prices through exchange closures. The constant maturity futures indices track the 30-day futures horizon specifically and trade when the underlying markets trade.

Both products fall within Pyth Indices, the company's commercial data product line. The enterprise tier, Pyth Pro, posted $7.49M ARR in July 2026 with 22% month-over-month growth.

What It Changes for DeFi Perpetuals and Structured Products

The constant maturity methodology has a long track record in traditional finance. The US Treasury has published constant maturity yields for decades, and the CBOE adopted a 30-day constant maturity approach for the VIX in 1993. Applying it to energy futures is new to on-chain markets.

For a protocol building on-chain perpetuals or structured products referencing energy prices, a constant maturity feed removes the need to build rollover logic, track expiry calendars, or handle the price gap that appears at each contract transition. The price series is continuous across the handover period that typically interrupts single-contract feeds.

Access to the constant maturity indices carries separate commercial terms within Pyth Indices. Organizations must apply through the Pyth Indices portal. Standard Pyth price feed subscriptions through Pyth Pro are a separate offering.
