The interest rates have nothing to with banks troubles in 2020. Would higher interest rates help. Sure. What has been the problem is all the provisions they have had to take because of the economy and the stuff going on with covid. Longer-term this won't be a problem for the banks because these losses will eventually go away and there balance sheets as a whole are strong. But look at most banks income statements, if provisions were normal earnings in most cases would be up y/y, and this is with record low interest rates. All is just my opinion, and I could always be wrong though.
