Deals Of The Day: The Latest In Wealth Management M&A – ARC Group, BNP Paribas, HSBC Private Bank

The latest mergers, acquisitions and other corporate actions in the wealth management sector.

ARC Group
ARC Group has completed the sale of its subsidiary ARC Research to S&P Dow Jones Indices, a division of S&P Global, after receiving regulatory approvals.  

The move to buy the wealth data and indices of ARC Research was first announced by this news service in July. 

The completion of the sale of ARC Research and its ARC Wealth Indices – the world's largest proprietary dataset of investment outcomes for private investor portfolios – will underpin the ARC Group’s strategy to expand its advisory division, which advises on $25 billion in assets for international families and charities. 

“There is no better home for ARC Research and the ARC Wealth Indices than S&P DJI. We look forward to hearing of the continued growth and success of the Indices,” Stephen McMahon (pictured below), CEO of ARC Group, said. “But the ARC Group will not be resting on its laurels. We are, perhaps, the largest multi-family office no one has ever heard of, but that is going to change. We have exciting plans for our private client and charity advisory business as we bring additional resources to bear following the S&P Dow Jones deal.”

“We are now solely focused on helping clients worldwide formulate and implement efficient investment strategies across all asset classes,” he added.

Operating from the UK and the Channel Islands, ARC's advisory business advises about 250 wealthy individuals, families and endowments on over $25 billion of assets invested across more than 200 banks and investment firms for clients from over 20 jurisdictions around the world.

BNP Paribas, HSBC Private Bank
BNP Paribas has finalised its acquisition of HSBC Private Bank's activities in Germany. This operation, announced on 23 September 2024, brings BNP Paribas Wealth Management combined assets under management to nearly €50 billion ($58 billion).

The acquisition marks a milestone in the development and growth journey of BNP Paribas Wealth Management in Europe. Germany is a key market for BNP Paribas, offering strong growth potential for wealth management activities, most notably with the German SMEs and the German entrepreneurs and families client segments. 

“This acquisition is a new crucial step for BNP Paribas Wealth Management as it enables us to more than double our size in Germany and to join the premier league of local German players,” Vincent Lecomte (pictured below), CEO of BNP Paribas Wealth Management, said.
