Boutique investment bank

A boutique investment bank is a non-full service investment bank that specializes in at least one aspect of investment banking, generally corporate finance, although some banks are retail in nature, such as Charles Schwab. Of those involved in corporate finance, capital raising, mergers and acquisitions and restructuring and reorganizations are their primary activities. Due to their smaller size, capital raising engagements are usually done on a best-efforts basis.

Boutique investment banks generally work on smaller deals involving middle-market companies, typically less than a billion dollars in revenues, and usually assist on the sell-side in mergers and acquisitions transactions. In addition, they sometimes specialize in certain industries such as media, health care, industrials, technology or energy. Some banks may specialize in certain types of transactions, such as capital raising or mergers and acquisitions, or restructuring and reorganization. Typically, boutique investment may have a limited number of offices and may specialize in certain geographic regions, thus the moniker, 'regional investment bank'.

During 2014, The Financial Times New York Times, and The Economist all published favorable articles regarding the growing trend of corporations to hire boutique investment banks. Reasons cited included their absence of conflicts, independence, and skill of one or a relative few individuals. The discrediting of traditionally conflicted Wall Street Investment Banking firms, especially those listed as Full-Service or Conglomerates on the List of Investment Banks, due to their role in the creation or exacerbation of the Great Financial Crisis is cited as a primary reason for the ascendancy of these boutique firms. However, advances in technology which permit the outsourcing of all non-core aspects of the firm have also been cited as a cause of this David versus Goliath phenomenon.

Working at boutique investment banks can be very different than working at larger banks, even though the majority of boutiques are founded and led by former partners at large banks.

As larger investment banks were hit hard by the Great Recession of the 2000s, many senior bankers left to join boutiques, some of which largely resemble the partnerships that ruled Wall Street in the 1970s and 1980s. Boutique investment banks took a greater share of the M&A and advising market at the same time.

There are many boutique investment banks, both in the U.S. and internationally.

Large, prestigious boutique firms include The Blackstone Group, Brown Brothers Harriman, and Piper Jaffray. While these may be national in scale, they are not international and full-service as are the so-called 'bulge bracket firms'.

Smaller boutiques are commonly not household names, but within their niche may be quite well known.
