UBS has successfully concluded its acquisition of Credit Suisse, resulting in a mammoth banking entity, as two global banks unite for the first time in history. UBS Chairman, Colm Kelleher, says “We are now one Swiss global firm and, together, we are stronger." Many obstacles still remain as the two banks will now focus on integrating internal operations. Both banks’ balance sheets will remain separate but UBS has created a new board of directors dedicated only to specific Credit Suisse operations. As billions of Swiss francs are said to be saved through the merger, Switzerland’s political leaders worry that the bank has grown too large for its own good.
