Proposal to amend frequency of some US base metals premiums

Fastmarkets proposes to amend the frequency of the publication of several US base metal price assessments to a monthly basis, including MB-PB-0006 lead 99.97% ingot premium, ddp Midwest US; MB-SN-0036 tin 99.85% premium, in-whs Baltimore; MB-SN-0011 tin 99.85% premium, ddp Midwest US; MB-NI-0240 nickel 4x4 cathode premium, delivered Midwest US and MB-NI-0241 nickel briquette premium, delivered Midwest US.

Fastmarkets selects the frequency of publication of a market after considering the number of data points (deals, bids, offers, deals heard and assessments) that it can reasonably expect to collect on a consistent basis over the selected period to support the price assessment process. This proposal follows preliminary discussions with the market as well as internal meetings to review relevant Fastmarkets data, which suggest a lack of spot liquidity and price volatility in recent years.

The main pricing day will continue to be Tuesdays (at 3-4pm London time), but these tin, lead and nickel premiums would be assessed once a month instead of fortnightly (tin) and weekly (lead and nickel).

The proposed new specifications are listed below, with the proposed amendment of price frequency in italics:
