You own a small bank in a state that is now considering allowing interstate banking. You oppose interstae banking because it will be possible for the very large money center banks in New York, Chicago, and San Francisco to open branches in your bank's geographic market area. While opponents of interstae banking point to the benefits to consumes of increased competition, you worry that economies of scale might ultimately force your now profitable bank of out business. Explain how economies of scale (if significant economies of scale in fact do exist) could result in your bank being forced out of business in the long run.

Take a shot. What do you think.

Hint: economies of scale means declining average costs as the size (output) of the company grows.

Economies of scale occur when the average cost of producing a good or service decreases as production volume increases. In the case of banking, it refers to the cost advantages enjoyed by larger financial institutions due to their size and scope of operations. If significant economies of scale exist in the banking industry, they can pose a threat to smaller banks like yours in the long run.

Here is an explanation of how economies of scale could potentially force your bank out of business:

1. Cost advantages: Larger banks can spread their fixed costs, such as technology infrastructure, regulatory compliance, marketing expenses, and employee salaries, over a larger customer base. This allows them to achieve greater efficiency and lower average costs per customer compared to smaller banks. Consequently, they can offer more competitive interest rates on loans and higher interest rates on deposits, attracting customers away from smaller banks.

2. Access to capital: Money center banks often have easier access to capital due to their larger size and reputation. They can tap into larger funding sources, access capital markets, and negotiate better loan agreements. This gives them a competitive advantage in providing loans to individuals and businesses, making it more difficult for smaller banks to compete on lending terms.

3. Advanced technology and services: Larger banks can afford to invest heavily in technological advancements, such as automated banking systems, robust online and mobile banking platforms, and sophisticated risk management tools. These advancements not only enhance customer convenience but also provide cost savings and operational efficiencies. Smaller banks may struggle to keep up with such investments, making it harder to attract and retain tech-savvy customers.

4. Diversification and specialization: Larger banks can offer a wider range of products and services, including investment banking, wealth management, insurance, and international banking. This diversification allows them to cross-sell and leverage their customer relationships effectively. Smaller banks typically have limited resources and expertise to compete in all these areas, limiting their ability to generate additional revenue streams.

5. Negotiating power and market dominance: As large banks expand across state borders, they gain significant market share and become dominant players. With more branches and larger customer bases, they can exert greater influence on pricing, market trends, and regulatory policies. This dominance can potentially put smaller banks at a disadvantage, making it harder for them to compete effectively.

To summarize, if significant economies of scale exist in the banking industry and larger banks are allowed to open branches in your geographic market area through interstate banking, they may achieve cost efficiencies, access to capital, advanced technology, product diversification, and market dominance. These advantages can gradually erode the market position and profitability of smaller banks, potentially forcing them out of business in the long run.
