BNP Paribas, one of the French banks mooted as a suitor for scandal-rocked Société Générale, has promoted one of the chief architects of its in-house trading platform to global head of fixed income trading and quantitative research.

Guillaume Amblard has been global head of interest rate and foreign exchange trading for two years and has worked at the bank since 1990. He will become global head of its fixed income trading and head the bank's research team for complex mathematical and statistical modelling for fixed income products.
