You missed that the “only” thing is not actually a difference, since the bank can deny access to the contents for a significant amount of time.
At this point, what y feldblum has to say about breach of contract is spot on. If the account is advertised as a demand deposit, then the money must be paid over immediately on demand or else the bank is either guilty of breach of contract, or, if the contract’s fine print allows for such delays, guilty of false advertising. The fact that a law may allow such actions is merely grounds for condemning that law. Without that kind of law, a bank cannot escape its legal obligations get away with it.
As to CD’s, it makes all the difference in the world because CD’s are not part of the core money supply. They are capable of being added on later as supplementary components, which is technically legitimate because one can indeed settle a debt by passing title on a CD to the creditor who can in turn do likewise with another creditor, but I raise an eyebrow at CDs’ inclusion because their trade like that is hardly a significant proportion of transactions even of those involving CD’s. For practical purposes, the purchase of a CD does not increase the money supply and is a real increase in credit that will help the economy along, whereas making a deposit into a fractional account does increase the money supply and the lending from that account is mere credit-expansionism that will come to no good end.
You also imply by your answer that “maturity” of a CD and time deposit correlates to the maturity of the loans to which they are applied.
I never implied any such thing. I only noted that a cashing in prior to maturity was not the same as a withdrawal.
On the technical side of the particular topic you mention, it is duration that matters more than maturity (your use of quotes suggests you know this). It is this practice you mention - called duration gap, for those who don’t know - that I had in mind when I said that the practice of FRB was not sui generis. I know very well that lending out for durations longer than as apply to one’s sources of funding is unsound (eg S&L crisis in the late 80’s and early 90’s), whether this is in reference to fractional reserve banking or not. This is one of the things that would be learned by Mr Wynand if he did what I recommended and researched what was good and bad about management of financial institutions. I didn’t mention it expressly before because I didn’t want to get into complicated mathematical concepts on a mere forum - it’s something for people to read and think about on their own time or learn in a proper educational environment.
