AFRA
The Average Freight Rate Assessment
AFRA is the acronym for average freight rates provided by the London Tanker Brokers Panel; these are essentially average (historical) freight rates that are assessed by the London Tanker Brokers for various tanker sizes. These rates are normally published on the of the month and are arrived at after assessing freight rates on all known fixtures in the open market and from information supplied by various oil companies.
They are used to fix freight rates for the transportation of oil cargoes, and taxation authorities use them to assess transportation costs.
