This is exactly how negative interest rate central bank policy is designed to work.

"A negative interest rate means the central bank and perhaps private banks will charge negative interest: instead of receiving money on deposits, depositors must pay regularly to keep their money with the bank. This is intended to incentivize banks to lend money more freely and businesses and individuals to invest, lend, and spend money rather than pay a fee to keep it safe."

Too bad the capital stock isn't determined by individuals but rather the Fed; who knows what the interest rate would be in real life if there wasn't massive money printing. Sorry, "quantitative easing"

So, something like inflation along with centrally directed GDP growth targeting?

Just look at the price of gold since 1970. And turn the chart upside down. That is the halflife of dollars.

Demurrage money.
