Market Definitions

The Federal Reserve Bank of Philadelphia has delineated the following banking markets for the Third Federal Reserve District. These market definitions are used by the staff of the Federal Reserve Bank when analyzing the competitive effects of proposed bank and bank holding company mergers and acquisitions for the Board of Governors of the Federal Reserve System. The Federal Reserve Bank of Philadelphia will consider modifying its market definitions when an applicant for merger or acquisition presents sufficient evidence to warrant a change in the Reserve Bank's definitions.

These definitions were constructed using MSA definitions, U.S. Census journey-to-work data, External Link and geographic facts.

The Federal Reserve Bank of Philadelphia analyzes the competitive effects of applications for mergers or acquisitions by quantifying the concentration of banking deposits in a banking market using FDIC Summary of Deposits data External Link to compute the Herfindahl-Hirschman Index.

For additional information concerning these banking market definitions, market tables, or questions about competitive analysis of bank and bank holding company mergers and acquisitions, contact James DiSalvo E-mail by e-mail or phone (215) 574-3820.

General Definitions

Please Note: The following definitions are general in nature. For actual regulatory applications, contact the examiner handling the application.

  • Market: For the purposes of banking mergers, the product market is the cluster of products and services defined in U.S. v. Philadelphia National Bank (374US321).  These products and services include: personal loans, business loans, mortgages, loans secured by securities or accounts receivable, automobile loans, tuition financing, credit cards, revolving credit accounts, demand deposits, time and savings deposits, estate and trust planning and trusteeship services, lock boxes and safety-deposit boxes, account reconciliation services, bankers' acceptances and letters of credit, correspondent services, and investment advice.  A proxy for the cluster is total deposits in the market.  The geographic market is the minimum area over which supply and demand for these products and services determine prices.
  • Herfindahl-Hirschman Index (HHI): a measure of competition in a market computed by summing the square of each competitor's market share.  Amarket with an HHI below 1,000 is considered unconcentrated; one with an HHI between 1,000 and 1,800  is considered to be moderately concentrated; and a market with an HHI above 1,800 is considered to be concentrated.  Department of Justice guidelines state that a banking merger is unlikely to be challenged unless the post-merger HHI exceeds 1800 and the increase in the HHI is at least 200.  For mergers that exceed these guidelines, applicants may present mitigating factors which will be reviewed based on relevancy of the economic analysis and data.
  • CR-4: Concentration ratio comprises the sum of the four largest competitors' shares.
  • Shaded Market Share: To account for the effect of competition from thrifts, thrift deposits are shaded by an amount that reflects their influence in the market.  All the market tables shade thrift deposits at 50 percent.
