Sam Horowitz joined the firm from Lloyds Banking Group and will report to Marex global head of FX Chris Eagle. Horowitz left Lloyds in June after joining the bank in October 2010 from Louis Capital FX. At Lloyds, he worked as director of eFX algorithmic trading.
Previously, he was an FX spot trader at Rabobank from 2001 to 2004 and an FX trader at UBS from January 2005 before moving to Louis Capital FX in London in April 2007.
Marex – which is run by a group of former Lehman Brothers executives – is in the process of building a new global FX business.
In March, Eagle told EuromoneyFXNews that the brokerage is planning to make a series of key hires for its currencies business this year to work in its operations in London, Geneva, New York and Singapore.
