Platts to change Medanito crude FOB typical cargo size effective May 1

Following industry feedback, Platts, part of S&P Global Commodity Insights, will revise its Medanito FOB assessment typical cargo size from 450,000 barrels to 600,000 barrels, effective May 1.

Platts also will include a 450,000-barrel minimum and a 750,000-barrel maximum for cargoes that would be included in these assessments.

Platts understands that cargoes loading on an FOB basis from the Puerto Rosales terminal in Buenos Aires, Argentina with adequate draft availability are consistently loading to about 600,000 barrels. Industry feedback indicates this cargo size has become the market standard in FOB trading in the region.

The assessments are published under the following Platts symbols:

Platts will reflect a typical cargo size within the minimum and maximum range of 450,000 to 750,000 barrels. For other cargo sizes within the above range, Platts may normalize these to a 600,000-barrel standard by considering freight cost and market feedback.
