The London Metal Exchange is consulting its members on how to spend $10m in fines it has gathered from rule breakers, including from traders that have been caught swearing and chewing gum.

Most of the money comes from penalties imposed by the LME on members for failures related to the warehousing and delivery of metals but the City trading institution also operates strict guidelines that include bans on swearing and chewing gum in the Ring, one of the last open outcry trading floors in operation.
