user: Is UBS a good bank

assistant: UBS Group AG is a multinational investment bank and financial services company founded and based in Switzerland. Co-headquartered in the cities of Zürich and Basel, it maintains a presence in all major financial centres as the largest Swiss banking institution and the largest private bank in the world. UBS client services are known for their strict bank–client confidentiality and culture of banking secrecy. Because of the bank's large positions in the Americas, EMEA, and Asia Pacific markets, the Financial Stability Board considers it a global systemically important bank.

Apart from private banking, UBS provides wealth management, asset management, and investment banking services for private, corporate, and institutional clients with international service. UBS manages the largest amount of private wealth in the world, counting approximately half of the world's billionaires among its clients. Despite its trimming of sell-side operations, UBS maintains a global investment bank and is considered a primary market maker. The bank also maintains numerous underground bank vaults, bunkers, and storage facilities for gold bars around the Swiss Alps and internationally. Partly due to its banking secrecy, it has been at the centre of numerous tax avoidance investigations undertaken by U.S., French, German, Israeli, and Belgian authorities. UBS operations in Switzerland and the United States were respectively ranked first and second on the 2018 Financial Secrecy Index.

As of May 2022, UBS is the third largest bank in Europe with a market capitalization of $63 billion. It is one of the eight global "Bulge Bracket" banks. It has over CHF 3.2 trillion in assets under management (AUM), approximately CHF 2.8 trillion of which are invested assets. In June 2017, its return on invested capital was 11.1%, followed by Goldman Sachs' 9.35%, and JPMorgan Chase's 9.456%. In late 2016, UBS established a blockchain technology research lab in London to advance its cyber security and encryption of client activities. Based on regional deal flow and political influence, UBS is considered one of the "biggest, most powerful financial institutions in the world". The company's capital strength, security protocols, and reputation for discretion have yielded a substantial market share in banking and a high level of brand loyalty. Alternatively, it receives routine criticism for facilitating tax noncompliance and off-shore financing. UBS is a primary dealer and Forex counterparty of the U.S. Federal Reserve.
