Banks can freeze your account if is flagged for suspicious activity, and you won’t be able to withdraw in some cases until the situation is clarified. The flagging is normally not going to be manual, but likely Machine Learning based nowadays, and will take into account multiple aspects from the data it has on you, and other people from the entity. That means that one person may get flagged, but not another using the same bank, despite both having made TXs to/from Exchanges. On top of that, there’s the general bank policy and procedures, the country’s Central Bank directives, the country’s stand, the global or local regulations, and so on. Overall, the experience from country to country is likely rather different, with some countries being more laxed than others.
Unfortunately, from a user’s perspective, it is seemingly random on the surface, although the above are likely under the hood. We tried to list pairs of
results on my local board (Spanish), but we don’t really have enough volume, and the cases seemed to vary from one experience to another, even using the same pair . Many seem to resort to proactively talking to their bank, in order to try to ensure that the TXs will go through without any hassle, which has its pros and cons, and is not going to achieve absolute certainty for all operations there on. Others wait for the problem to arise, if at all, and talk to their bank reactively, generally clearing the air after some stressful sessions.
