PRICING NOTICE: Proposal to amend fob Brazil alumina index

Metal Bulletin proposes changes to the specification of its fob Brazil alumina index.

The intention is to reduce the minimum tonnage for trades included in the index to 5,000 tonnes, from 10,000 tonnes at present. While it is understood that 5,000 tonne cargoes are rarely traded, this reduction will reduce the impact of non-transaction data (bids, offers, deals heard and assessment) on the final index calculation.

During times of low liquidity, non-transaction data is included in the index calculation, weighted at the minimum tonnage. Confirmed trades are given their full weighting in the final calculations.

In addition, Metal Bulletin intends to change the deadline for data submission to 3pm London time, from 2pm at present. The index will be published between 3pm and 4pm, London time, compared with between 2pm and 3pm at present.

The changes outlined above are in line with those proposed for Metal Bulletin’s fob Australia alumina index.

The fob Brazil alumina index is calculated as a discount or premium to the fob Australia benchmark, and will continue to be published fortnightly on Thursdays.

In addition Metal Bulletin intends to increase the frequency of its inferred fob Brazil alumina index to daily, to match the proposed daily publication of the benchmark fob Australia alumina index.
