Platts to launch volume-weighted average assessments for pipeline WTI Midland July 20

Platts, part of S&P Global Energy, will launch daily volume-weighted average (VWA) assessments of WTI Midland crude in Midland, Texas, July 20, 2026.

The following new assessments will complement Platts existing suite of WTI Midland assessments that follow a Market on Close assessment methodology. Platts Americas crude oil assessments can be found here.

New assessments:

Assessment Name Type Symbol
WTI Midland volume-weighted average Outright WTWAB00
WTI Midland volume-weighted average vs. cash WTI Differential WTMCA00
WTI Midland volume-weighted average vs. ICE HOU Differential WTICA00

The VWA assessments will reflect trades of WTI Midland delivered in Midland, Texas, for a minimum of 1,000 b/d, or 25,000 barrels for the prevailing spot month. Typically, these trades occur at the Enterprise Midland Terminal. Platts will reflect trades reported as flat price, a differential to cash WTI and as a differential to ICE HOU. Trades reported as a differential to these contracts may be normalized for inclusion in both the differential and outright assessments. For example, Platts may normalize trades of WTI Midland versus cash WTI back to an ICE HOU basis by using the difference between the NYMEX WTI and ICE HOU settlement values at 1:30 pm CT.

Platts understands most trading activity in this pipeline market occurs between 7 am CT and 1:30 pm CT. As such, Platts VWA assessments for WTI Midland will reflect trades executed in this time range, and market participants will need to submit trades to Platts before 2 pm CT.

For inclusion in the VWA assessments, trades submitted to Platts must clearly state the traded volume, price, trade location, and execution time. Platts may reach out to market participants to verify trade information and reserves the right to exclude any trades that do not meet Platts publishing guidelines.

While the ICE HOU contract expires three business days prior to the 25thcalendar day of each month, the spot month assessed for both differentials to cash WTI and ICE HOU will roll on the first business day after the 25thof the month, unless otherwise specified. After the expiration of the front-month ICE HOU contract, Platts may assess the ICE HOU value using information from adjacent markets. For example, from Jan. 26 through Feb. 25, the front month for US domestic pipeline barrels is March. On Feb. 26, the front month switches to April. If the 26th falls on a weekend or holiday, the next business day marks the beginning of the new trading month.

The assessments will be available on Platts Global Alert and Platts Crude Alert pages 210, 211, 214 and 215, and will be published in Crude Oil Marketwire , North America Crude and Product Scan and Oilgram Price Report.
