An overseas bank is currently undertaking a feasibility study looking into the possible launch of a new bank in the UK Preliminary findings suggest…

The preliminary findings describe a market where customers have significant influence. The facts that the market is saturated, customers have extensive choice, and switching costs are low are all classic determinants of high "Bargaining Power of Customers" (also known as Buyer Power) in Porter's Five Forces model. When customers can easily switch between competitors, they can exert pressure on banks to provide better services, lower fees, or higher interest rates, thereby reducing the industry's overall profitability.

A. Threat of new entrants: This force relates to barriers to entry (e.g., regulation, capital requirements), not the competitive dynamics customers create within the existing market.

C. Bargaining power of suppliers: This concerns the power of those providing inputs to the bank (e.g., technology vendors, capital providers), which is not addressed in the findings.

D. Threat of substitute products: This refers to alternative ways of meeting banking needs (e.g., fintech apps, credit unions), not the choice between similar, competing banks.

Page 82, "The Power of Buyers": Porter states, "Powerful customers... can force down prices, demand better quality or more service... all at the expense of industry profitability." He identifies low switching costs and a wide choice of vendors as key sources of buyer power. The scenario's findings directly align with this definition.

Section "Bargaining Power of Buyers": The lecture notes identify "Low switching costs" and "Product is undifferentiated" (leading to more choice) as primary factors that increase the bargaining power of buyers, which is precisely what the scenario describes.
