It depends on what we mean by the banks' transition to cryptocurrency. and Banks will provide services in cryptocurrency only if it is beneficial for them and there is no risk for them. They will not go to the use of cryptocurrency themselves in their banking operations. At the same time, they have already appreciated the benefits of blockchain technology and will use it to replace their outdated SWIFT method. They will also widely use their digitized national currencies, that is, stable coins of the central banks of states, and therefore it makes no sense for them to switch to cryptocurrency.
