PRICING NOTICE: Proposal to amend frequency of fob Australia alumina index

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

The intention is to increase the frequency of the publication of the index to daily (every weekday) from weekly at present.

Data collected over the past year shows it is possible to accurately normalise other Pacific origin data to the fob Australia base specification. Data relating to spot trades outside the base specification – namely, from Indonesia, Vietnam and India – will be normalised using in-house developed models based on regression analysis of collected data points.

The formal inclusion of these trades into the index brings additional liquidity into the calculation, supporting the increase in publication frequency without compromising the connection to the physical market.

In addition, Metal Bulletin will reduce the minimum tonnage for trades included in its 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.

Furthermore, in the absence of any trades on a given day, Metal Bulletin will roll over the last confirmed transaction for inclusion in that day’s index calculation.

The above measures will ensure that the daily alumina index is intrinsically tied to the physical market and confirmed spot transactions, even in times of low liquidity.

Finally, Metal Bulletin intends to change the deadline for data submission to 4pm London time, from 2pm at present. The index will be published between 4pm and 5pm, London time, compared with between 2pm and 3pm at present.
