I have been going through this process in order to clarify for myself the logic of the current discussion of so-called negative interest rates — an oxymoron if ever there was one. This is part five of the series; part one, part two, part three and part four can be found here. I hope it also will have some use to readers.
Part Five: The dollar and the increasing possibility of 21st Century Currency Warfare
Can monetary policy be rescued from oblivion? Probably not. There are just too many difficulties with the idea of negative interest rates on currency.
As I explained in part four of this series, Haldane proposes that the way around the zero lower bound on monetary policy may be to impose a negative interest rate on the holders of state issued currency. If a way could be found to force the holders of currency to pay interest on the currency in their bank accounts, wallets, pockets — and even in their mattresses — the distinction between credit money and currency could be forcibly imposed on society by the state despite a zero interest rate environment.
Once stripped of its deceptive wrapping as mere monetary policy, what Haldane is proposing is the outright expropriation of your savings account, your checking account and even the currency in your wallet and cookie jar. This goes well beyond monetary policy and begins to encroach on the limits of national economic policy itself. Under the most charitable interpretation, his proposal is well into the sphere of fiscal, even currency, policy despite the attempt to conceal it behind protective coloration as a negative interest rate on currency.
For the moment, however, let’s ignore this potential objection to his proposal. Instead, let’s treat it as a proposal for a measure similar to what FDR did in 1933: pure and simple devaluation of the currency.
What are the difficulties to be considered?
