What is the Argus North Sea Index® price assessment?
ANSI is a monthly index based on the last five days of the previous month Argus large cargo cif ARA assessments for propane and butane, less a freight element which is set on an annual basis. The freight element is based on average time charter rates for mid-size cargoes on North Sea routes. Prices are also converted to euro/t using the previous calendar month’s average European Central Bank exchange rate
How is this assessment used?
The ANSI price assessment is widely used in spot and term contracts throughout northwest Europe and reflects the huge, liquid market for large cargoes of LPG in Europe.
It is also used extensively in central and eastern Europe by refiners and wholesalers, and by other participants in internationally traded LPG markets.
