"ICAP is on track for a robust performance for the year despite the demanding economic environment," chief executive Michael Spencer said in a statement.
"We continue to focus on our operational efficiency. In the last three months we have seen an improvement in risk appetite in some markets. We expect to see a slow move towards more normalised markets as the year progresses," he added.
ICAP had said in February it expected profits for the year through March 2012 to be towards the upper end of an analyst forecast range of between £336m and £358m.
