A merchant bank is a financial institution that provides advisory, financing, and investment services to mid-sized private companies and high-net-worth individuals. Merchant banks do not take deposits from the general public and do not offer checking or savings accounts. Their business is entirely focused on helping companies grow, restructure, and access capital, not on daily retail banking transactions.
The U.S. merchant banking services market generated $15.4 billion in revenue in 2025, with the industry growing at a compound annual growth rate of 6.9% over the previous five years. There are approximately 680 merchant banking firms operating in the United States, most of them small, specialized boutiques.
Merchant banks occupy a specific position in the financial services landscape. They serve companies that are too large for traditional commercial bank products but not large enough or public enough to need the full-scale services of major investment banks. Think of them as bridging the gap between the local business banker and the Goldman Sachs deal team.
A company with $20 million in revenue looking to acquire a competitor, raise private equity capital, or structure a cross-border transaction is the archetypal merchant bank client. Public Fortune 500 companies use investment banks for these purposes. Smaller businesses use commercial banks. The middle market client belongs to the merchant bank.
Merchant banks are versatile by design. A single institution may combine several of the following service lines.

Merchant banking dates to 17th and 18th century Europe, where traders in France and Italy began financing other merchants' activities and facilitating distant currency exchange. The model spread to Britain and eventually the United States in the 19th century, with JPMorgan and Citibank tracing roots to this tradition. In the United Kingdom, the term "merchant bank" is still used interchangeably with "investment bank," which differs from the American distinction between the two categories.
