What is Platts American GulfCoast Select?

CONTACT US TO LEARN MORE >

Platts AGS reflects the value of light sweet crude oil loading 15-45 days forward on an FOB basis from locations along the US Gulf Coast including Houston, Corpus Christi, Beaumont, Nederland, Texas City, and Port Arthur, with the most competitive location on a cargo-size normalized basis setting the price assessment.

This crude oil assessment reflects a typical cargo size of 700,000 barrels, with bids, offers and trades between 550,000 and 800,000 barrels eligible for use in the assessment but normalized to reflect the freight economics of the typical cargo size. The assessment reflects the Platts WTI Midland grade supplied directly from the Permian Basin on the BridgeTex, Longhorn, Midland-to-Echo I/II, Cactus I/II, EPIC, Gray Oak, and Permian Express pipelines with API between 40 and 44 and .2% sulfur limit, among other specifications.

Platts American GulfCoast Select – Export Crude Commentary

  • Platts AGS assessed at $62.87/b as the differential to forward Dated Brent strip fell
  • US crude exports over week ending Feb. 26 estimated at 2.531 mil b/d: Kpler


Platts American GulfCoast Select was assessed at $62.87/b on Feb. 26, as differentials for the grade moved in different ways, depending on the basis.


Against the 15 to 45 day forward NYMEX WTI strip, Platts AGS was assessed 7 cents/b stronger on the day at a $1.60/b premium, while against the forward Dated Brent strip, the grade was assessed $1.17/b cents/b weaker at a $2.10/b cents/b discount.

The sharp fall for Platts AGS' differential against the forward Dated Brent strip, while the differential was little changed against the forward NYMEX WTI strip, can be attributed to Dated Brent falling fall less sharply on Feb. 26 than the NYMEX light sweet crude contract. While Dated Brent was assessed just under 89 cents/b lower on Feb. 26 at $65.92/b, while the front-month NYMEX light sweet crude contract settled $2.03/b lower on the day at $61.50/b.

US crude exports over the week ending Feb. 26 were estimated at 2.531 million b/d, according to Kpler, a data intelligence company, with flows rebounding from the week prior that saw severe winter weather, power outages and fog suppress exports. The estimate was up 665,000 b/d from Kpler's estimate for the week ended Feb. 19, while up just 217,000 b/d from the EIA's reported weekly export average for the week ended Feb. 19.
