Credit provisions and a record regulatory fine drove Carnegie's costs up by more than half in the third quarter as the Nordic investment bank today attempted to draw a line under the turmoil sparked by a trading scandal that erupted in May.

Expenses in the three months to September surged 59% to Skr629m (€68.4m) at Carnegie, which attributed the rise partly to a Skr50m fine levied by Swedish financial regulators in the wake of a probe into the trading scandal, and partly to Skr50m in credit provisions.
