Mark Johnson, the former global head of foreign exchange at HSBC Holdings Plc, failed to get the U.S. Supreme Court to hear an appeal of his 2017 conviction for front-running a $3.5 billion client order.

The high court rejected Johnson’s petition without comment. Justice Sonia Sotomayor did not participate in the decision. A federal appeals court in Manhattan previously rejectedBloomberg Terminal Johnson’s arguments that he didn’t know he was breaking U.S. law because no one previously had been prosecuted for wire fraud and conspiracy for similar conduct.
