Jefferies has become the latest bank to expand its credit sales and trading business, recruiting a senior credit analyst from BlueBay Asset Management, as the flood of hires in the sector by bulge-bracket banks and their fast-growing rivals continues.

The US investment bank has appointed Samantha Wessels as a managing director and senior credit analyst, based in London. She will work closely with Tom Jenkins, who joined Jefferies in March as a senior credit analyst from Royal Bank of Scotland.
