You would think that in a functioning market, a European bank could hoover up the savings market by offering 2.5% 7 days' access and placing it at ECB at 3%.
I have often thought similar. There would seem to be a real opportunity for a European bank to hoover up deposits and earn a return.
Is it because of rules on capital requirements that banks aren't able to do this, but the brokerage firms, which are not bound by the same regulations, are? Or is it just that the rise in interest rates has been so fast, and that there is uncertainty about how long the high rates will last, that causes the cautious banks (and State Savings) to not substantially increase their rates?
I appreciate that there are capital requirements but why would the capital requirements stop this? Surely, the capital requirements simply mean that x% needs to be retained as capital?
Banks (and the NTMA for State Savings) are not increasing rates because they can get away with it because few switch and they therefore increase their margins. In the US banks have experienced big outflows due to low rates, the same has not happened here.
