Digital transformation and bank loan pricing: New insights from an emerging market
This study demonstrates that digital transformation significantly reduces bank loan costs in Vietnam's emerging market by enhancing transparency and risk management, with the most pronounced benefits observed among large and state-owned banks due to their superior resources and infrastructure.

In the economies of many developing nations, the path to building a business or buying a home often runs through a single door: the bank. Unlike countries where companies can easily raise money by selling shares or bonds, places like Vietnam rely heavily on commercial banks to move money from savers to borrowers. In this system, the price of a loan—the interest rate a family or company pays—is more than just a number on a contract. It is a measure of how efficiently the financial system works. When banks can assess risk quickly and cheaply, they can offer lower rates, allowing more people to invest and grow. For decades, economists have wondered how the rapid rise of digital technology, from artificial intelligence to cloud computing, changes this dynamic. Does the shift toward digital banking simply make transactions faster, or does it fundamentally lower the cost of borrowing for everyone?
A team of researchers from the Banking Academy of Vietnam set out to answer this question by looking at the real-world experience of twenty-eight commercial banks over a seventeen-year period, from 2007 to 2023. They did not rely on surveys or simple yes-or-no questions about whether a bank had a website. Instead, they developed a method to measure the depth of a bank's digital transformation by counting how often words related to digital technology appeared in the banks' official annual reports. This approach allowed them to gauge the actual strategic focus and effort each bank was putting into modernizing its operations. By tracking these digital efforts alongside the interest rates the banks charged, the researchers could see if the two were connected.
The study found a clear and consistent pattern: banks that embraced digital transformation more deeply were able to offer loans at lower costs. As a bank increased its digital capabilities, the interest rates it charged to borrowers tended to drop. The researchers identified several reasons for this shift. First, digital tools allowed banks to gather and analyze more information about borrowers, reducing the uncertainty that usually leads to higher interest rates. When a bank knows more about a borrower's reliability, it does not need to charge as much to protect itself against potential losses. Second, automation streamlined the paperwork and administrative work involved in approving loans, cutting the internal costs of doing business. These savings were then passed on to the customers in the form of cheaper credit. Finally, the presence of digital competition forced traditional banks to keep their prices competitive to retain their customers.
However, the benefits of this digital shift were not shared equally across the banking sector. The researchers discovered that the size and ownership of a bank played a significant role in how much it could lower its loan prices. Large banks and those owned by the state saw the most dramatic reductions in lending costs. These institutions possessed the financial resources to build advanced technological infrastructure and the government backing to drive large-scale digital initiatives. In contrast, smaller banks and those owned by private shareholders saw much more modest improvements. These smaller institutions often faced constraints, such as limited budgets and a lack of specialized staff, which made it difficult for them to fully capitalize on the efficiencies that digital tools could offer.
The findings suggest that while digital transformation is a powerful tool for making credit cheaper and more accessible, it also has the potential to widen the gap between large, well-resourced banks and smaller ones. In Vietnam, where the banking system is the primary engine for economic growth, this distinction matters. The study indicates that the state-owned banks, which have led the way in adopting digital strategies, have been able to translate these investments into significant cost savings for borrowers. For the banking system as a whole to become more efficient and inclusive, the researchers suggest that support is needed to help smaller banks catch up. By investing in shared digital infrastructure and building the capacity of smaller institutions, policymakers can help ensure that the advantages of the digital age are distributed more evenly, allowing all borrowers to benefit from lower costs and better access to finance.
