Platts launches Johan Castberg crude eWindow instruments July 15, 2025

Platts, part of S&P Global Commodity Insights, has launched eWindow instruments for its Johan Castberg crude assessment in the Platts Market on Close assessment process, July 15, 2025.

Participants in the MOC process are able to submit bids or offers for publication directly through the eWindow communication tool or do so through an editor who can then publish the bids and offers using the software.

Participants are able to submit bids or offers for publication as a differential to Platts Dated Brent, Cash BFOE, or as a flat price.

Johan Castberg eWindow instruments are on a Cost-Insurance-Freight (CIF) basis with a volume of 700,000 barrels in line with the grade's assessment.

Platts has established clearly defined timing guidelines and standards of incrementability that apply when publishing bids and offers in the MOC in order to ensure an orderly and transparent price assessment process.

TIMING: All bids and offers for eWindow must be submitted by 3:45:00 pm local time in London. Following any trade, market participants have one minute to rebid or reoffer. No price changes are allowed in the final five minutes of the MOC, which closes at 4:30:00 pm local time in London.

INCREMENTABILITY: Bids and offers may be improved by a minimum of $0.01/b every 60 seconds, or a maximum of $0.05/b every 60 seconds.

As per Platts editorial guidelines, market participants can withdraw a bid or offer from the MOC at any time, so long as no other potential trading counterparty has indicated interest to buy or sell into the bid/offer.

Platts eWindow provides direct entry and management of credit filters which should mirror those normally applied outside of the Market On Close assessment process.

Guidelines for the publication of bids and offers in the MOC are published in the Oil Timing and Increment Guide available here: www.spglobal.com/platts/en/our-methodology/methodology-specifications/oil/oil-timing-and-increment-guidelines.
