Merits and demerits of chain banking?

Chain banking, where multiple banks are linked through ownership or management, offers several merits, including increased stability and shared resources, which can enhance risk management and capital availability. It can also lead to greater efficiency in operations and a broader reach for services. However, demerits include the potential for systemic risk, as failures in one bank can impact the entire chain, and reduced competition, which may lead to higher fees and less innovation. Additionally, it can create complexities in regulatory oversight and accountability.
