JP Morgan earned the most from companies looking to access the capital markets in the first half of the year, according to preliminary figures from Dealogic – some good news for the US bank, whose reputation took a knock in the Spring on the back of a multi-billion dollar trading loss.

JP Morgan currently sits at the top of both Dealogic's equity and debt capital market league tables in terms of revenue for the first half of 2012. The bank earned $509m from work in the ECM markets over the period and $777m from DCM work.
