Frequently asked questions

How are LMEmini and ‘parent’ metal contracts margined?
LME does not have its own clearing house and initial margins are set by LCH.Clearnet in agreement with LME. LCH.Clearnet uses London SPAN methodology for its margining. An LME member may, however, charge a different initial margin to its clients than LCH.Clearnet requires from its members.

If a member or client wishes to calculate London SPAN margins, LCH.Clearnet risk parameter files may be downloaded from LCH.Clearnet website. London SPAN can be programmed into members' systems, or alternatively PC London SPAN, a specially designed PC software program can be used to work out the calculations. More details of PC London SPAN are available on the LCH.Clearnet website: http://www.lch.com/services/technology/pcspan.asp.
