What is alleged to have happened

The Financial Conduct Authority issued its final notice on October 30, 2018.

Mathew was convicted on June 29, 2016 of one count of conspiracy to defraud in respect of fixing USD LIBOR and sentenced on July 7, 2016 to four years' imprisonment. The FCA concluded the conviction showed a clear lack of honesty and integrity and made a prohibition order effective from the date of the notice.

The earlier insider-trading tag came from the standard guidance list of offences the FCA considers and has been removed.
