Answer:
The Fed cannot control the amount of money that households choose to hold as currency.
Step-by-step explanation:
Every couple of years some congressman (or woman) proposes that the $100 should be eliminated, basically for three main reasons:
- over 60% of US currency is held overseas
- the use of cash can be eliminated or reduced through banking services, e.g. debit and credit cards, checks, etc.,
- only illegal activities actually need $100 bills to move large amounts of money.
Reasons 1 and 3 make it virtually impossible (or impractical) for the Fed to control the money supply in the US. One of the main arguments in favor of reason 2, was that the Fed would increase its control over the money supply, at least the legal money.
Lately, as banks offer more services, the percentage of cash held by households has been decreasing, but as we saw this past weeks with the stock crash due to COVID-19, when something goes wrong, we all run to cash. Everyone started to withdraw all the cash they could from ATMs and banks.
