The concept of one-stop banking revolves around banks providing financial services jointly, which can potentially reduce costs due to complementarities in production or increase revenues from complementarities in consumption. However, the existence and impact of these potential cost and revenue economies of scope are subject to debate. While some sources suggest that cost economies of scope between bank deposits and loans are minimal, others explore the potential benefits of revenue economies of scope. This introduces the question of whether consumers pay for one-stop banking and if so, what the implications are for their financial management and overall welfare.

What You'll Learn
Consumers don't pay for one-stop banking
Consumers do not pay extra for one-stop banking. While banks may reduce costs by jointly providing financial services, this does not result in higher revenues from consumers. This holds true for both small and large banks, regardless of their position on the revenue-efficient frontier.
The concept of one-stop banking refers to banks offering multiple financial services together, such as bank deposits and loans. The idea is that by providing these services jointly, banks can benefit from economies of scope, either on the cost side or the revenue side. Cost economies of scope occur when the joint production of services reduces costs due to complementarities in production. On the other hand, revenue economies of scope happen when joint consumption leads to increased revenues due to complementarities in consumption.
However, evidence suggests that the synergies between bank deposits and loans are minimal and concentrated in cost savings through joint production rather than increased revenues from joint consumption. In other words, while banks may save some money by offering these services together, they do not make significantly more money by doing so. This lack of complementarities between deposits and loans indicates that claims about the benefits of expanding banking powers should be viewed with skepticism.
The absence of significant revenue complementarities was examined over a 12-year period, from 1978 to 1990. During this time, there was no evidence that revenues were larger when deposits and loans were provided jointly rather than separately. As a result, consumers did not pay extra for the convenience of one-stop banking. This finding was consistent across different types of banks, including small and large institutions, and those on and off the revenue-efficient frontier.
While consumers may or may not appreciate the convenience of one-stop banking, they do not incur additional costs for this service model. The findings highlight the importance of understanding the dynamics between cost savings and revenue gains in the banking industry and provide insights into the pricing strategies employed by banks offering bundled financial services.

Cost economies of scope
One-stop banking refers to the provision of multiple financial services by a single bank. In theory, this should result in cost economies of scope for the bank, which may or may not be passed on to the consumer in the form of lower prices.
Several studies have examined the presence of cost economies of scope in the banking industry. L. Allen and Rai (1996) estimated economies of scale and scope while controlling for X-efficiency, using an equation that considered total costs, outputs, and input prices of banks. Their results suggested that cost economies of scope may exist in banking.
Berger, Hancock, and Humphrey (1993) also found evidence of cost economies of scope based on the profit function, which takes into account cost gains from joint production. They concluded that for most firms, the optimal quantity of every output is positive for all price vectors observed in the data, indicating that joint production can lead to cost savings.
However, other studies have found limited evidence of cost economies of scope in banking. Berger, Humphrey, and Pulley (1996) estimated a revenue function using data on US banks from 1978-1990 and found no evidence of revenue scope economies between loans and deposits. Similarly, a study examining one-stop banking specifically found that cost economies of scope between bank deposits and loans were small and concentrated in joint production, rather than joint consumption.
In summary, while the concept of cost economies of scope suggests that banks may reduce costs by providing multiple financial services jointly, the empirical evidence on this topic is mixed. Some studies have found evidence of cost savings, while others have not. It is important to carefully consider the specific services offered, the structure of the banking industry, and the time period examined when evaluating the presence and magnitude of cost economies of scope in one-stop banking.

Revenue economies of scope
Consumers do not pay extra for one-stop banking. That is, revenues are no larger when deposits and loans are provided jointly rather than separately. However, banks may reduce costs due to complementarities in production (cost economies of scope) or raise revenues from complementarities in consumption (revenue economies of scope).
The potential for revenue economies of scope in one-stop banking lies in the cross-selling and up-selling opportunities it presents. By understanding a customer's financial situation and needs, banks can offer tailored solutions that draw on their range of products and services. For example, a customer who opens a savings account may also be interested in a mortgage or investment product to grow their wealth. Banks can also generate revenue through referral fees and partnerships by connecting customers with relevant financial products and services provided by third parties.
However, it is important to note that the effectiveness of revenue economies of scope depends on the existence of complementarities between the financial services offered. If there is little synergy or demand for the bundled services, the strategy may fall short. For instance, studies examining the relationship between bank deposits and loans found limited evidence of significant revenue complementarities over the period from 1978 to 1990. This suggests that banks should exercise caution when assuming that expanding their range of services will automatically lead to increased revenue.
In conclusion, while one-stop banking does not directly result in higher prices for consumers, it can be a revenue-generating strategy for banks if executed effectively. Banks need to carefully consider the demand for their services and the potential for complementarities to drive revenue growth through one-stop banking offerings.

Lack of complementarities between deposits and loans
Consumers do not pay extra for one-stop banking, despite the potential benefits to banks of offering joint services. This is due to the lack of complementarities between deposits and loans, which is where benefits are most likely to occur.
Banks may reduce costs through cost economies of scope when providing financial services jointly. However, these cost savings between deposits and loans have been found to be small. Over the period 1978-1990, revenue economies of scope were found to be insignificant for small and large banks, both on and off the revenue-efficient frontier. This suggests that there is a lack of revenue complementarities between deposits and loans.
The lack of significant synergies between deposits and loans has implications for banks considering expanding their powers. Firstly, it indicates that consumers do not pay extra for one-stop banking, even if they may value the convenience. Secondly, it highlights that banks' ability to lend is not solely dependent on their deposits. While deposits can provide reserves and funding for loans, banks with limited deposits can still lend through other means, such as using their capital or raising funds from other sources.
Additionally, there is a risk of asset-liability mismatch when banks have substantial long-term assets funded by short-term liabilities, such as deposits. This mismatch can lead to liquidity problems and even financial failure if liabilities become due before assets. The impact of such mismatches has been observed in various economic crises, including the 2007 Subprime Mortgage Crisis.
In conclusion, the lack of complementarities between deposits and loans suggests that consumers do not pay extra for one-stop banking. Banks' lending capabilities are influenced by multiple factors, including capital and other funding sources, rather than solely relying on deposits.

Banking powers expansion
Consumers do not pay extra for one-stop banking, despite the potential value they may place on the convenience of this service. This is because there is little evidence of revenue complementarities between deposits and loans, which are provided jointly by one-stop banks.
The discussion surrounding the expansion of banking powers is centred around the potential benefits and risks involved. Some believe that allowing banking organizations to increase their activities and access non-traditional lines of business could provide advantages. However, it is challenging to determine the exact impact of this expansion on the banking industry and the Bank Insurance Fund's (BIF) financial difficulties.
If decisions are made to expand banking powers, it is recommended that reforms are implemented to strengthen bank regulation, supervision, and operations, rebuild the BIF, and enhance bank holding companies. These safeguards are crucial to prevent risks and maintain competitive equity as new powers are phased in.
Additionally, allowing commercial firms to acquire banking organizations is generally seen as inappropriate due to the limited information available and the potential for industry problems to be exacerbated by competitors and market forces.
While there may be potential advantages to expanding banking powers, a cautious approach is necessary to ensure the stability and equity of the financial system. The GAO (U.S. Government Accountability Office) supports modernizing the U.S. financial system but emphasizes the importance of careful implementation and oversight to manage any potential risks effectively.
