The Depository Trust and Clearing Corporation is on track to boost UK staff numbers to 700 by the end of 2015 after hiring around 200 staff in the past 18 months, with the lion’s share of the new arrivals joining its office in north Wales.

The firm, which acts as the clearing house for the US equity market but has a number of subsidiaries covering the European post-trade process, has been on an 18-month hiring spree centred on its operations in Wrexham, where its entity data subsidiary Avox that was acquired in 2010 is based.
