It means that the banks too unnecessary risks for profit. Banks are supposed to be conservative institutions, financially, where they don’t take much money out incase they have a bank run or something.
Instead of whatever historical ratio was considered a safe ratio between having money in the bank or loaned out or invested, the banks decided to have less money in the bank that the historical average. This puts them at risk for if too many people try to take money out.
I’m sure there is other reasons, but I’m only concerened with the one, because it directly affects if you can get your money back or not.
I still have no idea what you’re talking about. Can you give me an example of an “unnecessary risk” in the banking industry? Up to this point I have see no evidence of systemic bank problems related to what would traditionally be considered high-risk investments.
