Platts proposes to amend methodology of Supramax scrubber premium index Sep 1

Platts, part of S&P Global Energy, proposes to amend its methodology for assessing the scrubber premium index, PSSI for Supramax (ASCRS00), to better reflect the global scrubber premium on Supramax ships through a trade-flow weighted basis, effective Sept. 1.

Currently, the PSSI index is assessed as a simple average of the difference in time charter equivalent of scrubber-fitted and non-scrubber ships across the routes assessed by Platts for Supramax ships.

Platts proposes to change the methodology for PSSI assessment by considering the difference between the GSP 11S Index (AIDYB00, basis scrubber-fitted) and the GSP 11 Index (AIDYA00, basis bunker fuel 0.5%).

Since the indexes (GSP 11S and GSP 11) are global trade-flow weighted averages, the new scrubber premium index would better reflect the earning differential for scrubber-fitted ships. The proposed change would also align the Supramax scrubber premium index methodology with that of the Capesize and Panamax segments, which were amended on Oct. 1, 2024 .

The assessments follow a 5:30 pm Singapore timestamp and appear in Platts Dry Freight Wire and Dry Freight Wire Monthly.
