BNY Mellon fires senior currency trader

• The firing is the first from either BNY Mellon (BK -0.3%) or any of the custodial banks sine the global probe into currency trading began last year - a sign the investigation has spread past the group of dealer banks which earlier this month agreed to pay $4.3B in fines over the matter.
• Jon Smailes was a senior trader on the London spot desk at BK, and was fired months ago based on the findings of an internal review which found his e-mails broke bank compliance rules - his exit wasn't disclosed before now. The bank informed the U.K.'s FCA of its findings and Smailes' firing, but isn't currently under investigation in the U.K.
