What kind of enterprise is the single product structure of traditional banks similar to?

It is similar to the traditional large-scale manufacturing enterprises.

Just as the products of traditional banks mainly focus on basic financial services such as deposits, loans and credit cards, and lack diversity, large manufacturing enterprises usually focus on producing one or several products, and their business scope is relatively narrow. This single product structure may lead to the risk exposure of enterprises to some extent. Traditional banks may face the risk of financial market fluctuations and interest rate changes, and manufacturing enterprises may be affected by changes in market demand and fluctuations in raw material prices.
