Platts to update AG-Asia freight netback calculations for refined products from Jan. 3

Platts, part of S&P Global Commodity Insights, will update its base rate calculations for clean freight netback assessments between the Arab Gulf and Asia for gasoline, naphtha, jet fuel/kerosene and gasoil with effect from Jan. 3, 2023, to reflect more closely current market conventions.

Platts first proposed these changes in a subscriber note published July 7:

Platts will first multiply the daily freight spot assessment expressed as a Worldscale rate to the corresponding flat rate, and then add any additional port charges and/or fixed differentials separately.

This differs from current calculations where the flat rates and additional port charges and/or fixed differentials are added together to form the base rate, which is then multiplied by the daily freight spot assessment to produce the final freight netback value.

An example of the change to the freight netback calculation would be based on the following Arab Gulf to Japan naphtha calculation:

A - Flat rate calculations for AG to Japan: Quoin Island to Chiba/Yokohama flat rate

B - Average of the following: Jubail/Mina Al Ahmadi to Quoin Island flat rate Mina Al Ahmadi/Ras Tanura to Quoin Island flat rate Ruwais/Mina Abdulla to Quoin Island flat rate AG to Japan = total of A and B

C - Average of fixed differentials applied at relevant ports, in this instance at Jubail and Ras Tanura, across the three routes.

Formula: Freight = (Spot WS x 55 / 52.50 x (A+B)) + C

The actual freight applied to derive the netback fluctuates daily based on changes to Platts freight assessments, as published in Platts Clean Tankerwire, applied against the respective annual basis rates. The affected freight netback assessments are published in Platts Asia-Pacific/Arab Gulf Marketscan, on Platts Global Alert page 902, Platts Refined Product Alert page 902, Platts Tanker Alert pages 2910, 2911, Platts Shipping Alert pages 352, 353 as well as in the Platts price database under the codes below:
