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, Permian Express pipelines with a limit .2% sulfur, 75 ppm mercaptans, and API between 38 and 44.

Platts American GulfCoast Select – Export Crude Commentary

  • Platts AGS outright continues to slide, assessed at $42.24/b
  • US crude exports this week averaged 3.55 mil b/d: cFlow


The outright price for Platts American GulfCoast Select continued to slide on Aug. 7, falling in line with major global crude futures, as US crude exports were estimated at 3.55 million b/d, according to Platts cFlow trade-flow software.


Platts AGS was assessed at an outright value of $42.24/b on Aug. 7, down 70 cents/b on the day, falling in line with both NYMEX light sweet and ICE Brent crude futures. The front-month NYMEX light sweet crude contract settled 73 cents/b down on the day at $41.22/b, while the front-month ICE Brent futures contract at the Houston market on close, or 1:30 pm CT, was assessed 77 cents/b down at $44.32/b.

US crude exports for the week ending on Aug. 7 were estimated at 3.55 million b/d by cFlow, with strong exports to Europe continuing. Crude exports to Europe were estimated at 1.55 million b/d, the highest since the week ended on July 10. Landings of US crude in Europe during August are expected to be strong by market participants, at over 1 million b/d. Those volumes could, however, fall in more forward months as sources have said that the arbitrage to the region was tightening. Since the week ended on July 3, US crude exports to Europe have averaged 1.38 million b/d, according to cFlow data.

While US crude exports were once again estimated by cFlow over 3 million b/d, for the eighth such week in a row, weekly export figures released by the US EIA have consistently been lower than estimates by cFlow, and other independent vessel-tracking platforms. Since the week ended on June 26, cFlow estimates have averaged 730,000 b/d higher than the weekly EIA export figure.
