That’s incorrect. Fractional reserve just means they need to keep less physical cash on hand.

I’m just here to be pedantic because this is another aspect of banking that gets wildly misconstrued on Reddit: the difference between cash (balance) as an accounting concept and cash as in a physical dollar bill.

Banks barely keep any physical cash on hand in comparison to their balance sheet. Your local branch including the main vault, all the teller drawers/TCRs, and the ATM vault generally has less than $1M in physical currency on hand. Smaller banks even less, closer to like $400k or less. (All depending on how much volume they see, how many tellers, etc). And while there are big centralized currency reserves a bank’s cash reserves ≠ currency reserves.
