ZURICH, June 30 (Reuters) - Credit Suisse is considering centralising the management of its bankers to the world’s wealthy, replacing a regional structure, three sources said, as part of efforts to fast-track an overhaul after a series of scandals. The Swiss bank and its board are looking to decide on a fresh strategy as soon as October after meeting in the mountain town of Bad Ragaz, two sources familiar with the thinking of senior executives said. Re-imagining the most prized part of Credit Suisse illustrates how deep this overhaul is likely to be, with executives discussing folding the private banking business and other services managing money for the world’s rich into one global division, the three sources told Reuters. Targeting the client managers who deal with its wealthiest clients, many of whom are worth tens of millions of dollars, would scrap a regionalised structure introduced in 2015. Such a change would reel local managers in Asia and internationally, who have enjoyed considerable autonomy, under tight Swiss control as well as making it easier to cut costs. Credit Suisse declined to comment. Its larger Swiss rival UBS adopted a unified global wealth management structure by combining its businesses servicing American and international clients into one global division in 2018, allowing it to trim costs. DEFENCE STRATEGY Credit Suisse executives and board members convened recently in Bad Ragaz, best known for its spas and thermal baths, for an annual strategy meeting. The executives are concerned that Switzerland’s second-largest bank, which has been hit by two scandals this year, could face break-up calls from investors, or that its shrinking stock-market value makes it a foreign takeover target. A domestic merger with UBS, something that has been discussed in the past, is viewed as a more palatable option, three sources also told Reuters last week. Managers did not formally discuss mergers at Bad Ragaz, with the possibility of a tie-up “the elephant in the room”, one source said after the meeting. Under the direction of its new chairman Antonio Horta-Osorio, Credit Suisse is looking to overhaul operations and prime its businesses to protect it from investor pressure. By combining its wealth management businesses, Credit Suisse would be able to streamline products, while also becoming more attractive to a potential merger partner, one source said. A global entity could also work better with the investment bank, which provides financial services to entrepreneurs and ultra-wealthy families, two of the sources said. A combined unit may get new leadership, the sources said, adding that Horta-Osorio was driving key decisions on the bank’s overhaul and its management. A merged wealth management unit could either combine the Asia-Pacific and International Wealth Management divisions, or further fold in the bank’s private banking business for ultra-wealthy customers in its home market, which now sits in its Swiss division, one source said. Credit Suisse lost more than $5 billion in the rush to unwind trades by family office Archegos and faces legal action for helping clients invest $10 billion in bonds issued by collapsed supply chain finance firm Greensill Capital.
