A dash means the release did not state a figure we could extract, not that the figure is zero. Penalty and disgorgement are stored separately so aggregates across the library do not double-count the same dollars. This regulator states penalties in GBP. The figure is recorded as published and is not converted, so it does not appear in the USD totals or medians used elsewhere on this site.

This library tags the matter as benchmark submission rigging, price manipulation and wash trading, based on the conduct the regulator describes. Each tag links to a page explaining how that technique works, what statute it engages, and what penalties comparable actions have attracted. The tagging is ours, not the regulator's: agencies charge statutory provisions, not technique names.

For the regulator's own account of the facts, read the primary document linked above. This page deliberately summarises the structured record rather than reproducing the release.
