Dexia Group, the Franco-Belgian bank, is stepping up its complex derivatives and structured loans business and has installed a new system designed by SunGard, the technology firm, to support valuations of its portfolios.

Dexia will use a system developed by SunGard's Reech unit, which specialises in systems for risk management and independent portfolio valuations. It will allow the firm to manage and analyse the market risk, credit risk and liquidity risk in their portfolios.
