In their operations, banks are subject to oversight and regulation from central banks. If central banks established a clear framework regarding Bitcoin, it is highly likely that most banks would be more open to adopting or at least facilitating Bitcoin-related services, whether in the form of custody or ETFs. However, current banking regulations on Bitcoin remain limited, as banks are not yet allowed to directly invest in Bitcoin as part of their reserves. At most, they are only permitted to facilitate Bitcoin-related services, and even then, only in certain countries, while the majority still prohibit banks from engaging with Bitcoin. But if allowed, we might see some banks would likely start small allocations to Bitcoin.
