Based in Hong Kong, El Khoury will be responsible for flow, structured and warrant derivatives trading across the region. He will report to Arnaud Bastit, head of equity trading for Asia-Pacific.
El Khoury joins Nomura from Deutsche Bank in New York where he most recently served as the co-head of equity derivatives trading for North America.
He has more than 15 years of experience in equity derivatives trading, and has previously worked as head of index derivatives flow trading at Morgan Stanley in New York and for JP Morgan in London.
Bastit said Nomura is already a top liquidity provider in key global exchanges and commands leadership in equity research.
"Jean has a great reputation in the market and his extensive experience in derivatives trading will be instrumental in serving our clients in the region," Bastit said.
