The former head of Royal Bank of Scotland’s principal strategies group, one of the trading units that invested the bank’s money before it was wound down this year, has resurfaced at interdealer broker Tradition about seven months after he left the UK bank.

Steven Behr, who ran a team in London that invested RBS' money in structured debt, including securities backed by infrastructure assets and emerging market mortgages, joined Tradition in March, according to the UK Financial Services Authority register.
