About
HSBC is one of the world's largest and most internationally connected banks, founded in 1865 in Hong Kong and Shanghai to finance trade between Europe and Asia and now headquartered in London, United Kingdom. Built on 160 years of cross-border banking expertise, HSBC's core competitive advantage is its unmatched network spanning Asia, Europe, the Middle East, and the Americas — a reach that enables it to serve multinational corporations, institutional investors, and affluent individuals who require banking services across multiple jurisdictions from a single relationship. This international connectivity is HSBC's defining strategic asset and the foundation of its wholesale and wealth banking franchises.\n\nHSBC's business is organized around Global Banking and Markets, Commercial Banking, Wealth and Personal Banking, and its dominant Asia franchise. The bank serves 40 million customers globally, with particular strength in Hong Kong, mainland China, the United Kingdom, and Southeast Asia — markets where its local presence, regulatory relationships, and brand trust give it advantages that global competitors struggle to replicate. In 2024, HSBC completed a strategic restructuring under CEO Georges Elhedery, consolidating its business units and divesting non-core operations in Canada and a portion of its French retail business to sharpen focus on high-return markets and client segments.\n\nHSBC reported more than $66 billion in revenue for 2024, driven by interest income strength, fee-based wealth management growth, and resilient transaction banking volumes. The bank's pivot toward Asia-linked wealth management and its cross-border trade finance capabilities position it to capture the expanding wealth of the Asian middle class and the growing complexity of multinational supply chains. As geopolitical fragmentation makes international banking more operationally complex, HSBC's deep local presence in key markets and century-long relationships with global trade networks give it a structural advantage that newer digital banks and regional competitors cannot replicate.
