Background of this survey
In recent years, generative AI (GenAI) has been rapidly penetrating society, and Japanese financial institutions are progressing its use with a focus on improving the efficiency of existing operations.
On the other hand, when financial institutions try to promote GenAI in their business, they need to recognize the risks specific to GenAI, such as information leakage and hallucination, and continuously review their operating rules in accordance with technological innovation and changes in risk.
With these issues in mind, the Bank of Japan conducted a survey on the use of AI, etc., targeting 153 financial institutions. This is the second survey following fiscal year 2024.
Conclusion
The findings from the survey results are listed below:
- The results of the FY2025 Survey show that the use of GenAI was expanding rapidly: About 50% of the financial institutions were already using GenAI, with this figure rising to over 70% when those currently undertaking trials was included, and to over 90% when those considering trials or use was included.
- Regarding the purpose of introducing GenAI, the number of financial institutions that aimed at "improving operational efficiency and reducing costs" and "information gathering and advanced analytics" increased significantly compared with the previous results. The number of financial institutions aiming at "improving customer service", "risk management" and "increasing revenue"-- which had a low response rate in the previous survey-- also increased.
- Regarding the evaluations after adopting GenAI, the number of financial institutions that responded "exceeded expectations" or "mostly met expectations" increased. As for new application areas, such as "creation of loan approval documents", "marketing" and "support for call center operations", the financial institutions gave reasonably positive feedback.
- Regarding the management status of GenAI, a significant increase was observed in the number of financial institutions that developed practical rules and clearly stated organizational policies. On the other hand, about 50% of respondents answered that "there is room for improvement" or "under consideration", in such areas as the monitoring of usage status, countermeasures against third-party risks and cyberattacks, and reviewing practical rules.
Based on the results of this survey and trends in the world, it is expected that financial institutions will continue to expand the use of GenAI, and that they will adopt it in areas that are expected to lead to top-line revenue, such as customer services.
On the other hand, when financial institutions use GenAI for customer service, they need to address issues such as GenAI-specific risks, third-party management, and accountability to users. In addition, it is necessary to pay attention to new risks that may arise from the use of new technologies (such as problems caused by unexpected behavior of AI agents).
