Deutsche Bank: Negative Rates Confirm The Failure Of Globalization
Misconceptions about negative rates
Understanding how negative rates may or may not help economic growth is much more complex than most central bankers and investors probably appreciate. Ultimately the confusion resides around differences in view on the theory of money. In a classical world, money supply multiplied by a constant velocity of circulation equates to nominal growth. In a Keynesian world, velocity is not necessarily constant – specifically for Keynes, there is a money demand function (liquidity preference) and therefore a theory of interest that allows for a liquidity trap whereby increasing money supply does not lead to higher nominal growth as the increase in money is hoarded. The interest rate (or inverse of the price of bonds) becomes sticky because at low rates, for infinitesimal expectations of any further rise in bond prices and a further fall in interest rates, demand for money tends to infinity. In Gesell’s world money supply itself becomes inversely correlated with velocity of circulation due to money characteristics being superior to goods (or commodities). There are costs to storage that money does not have and so interest on money capital sets a bar to interest on real capital that produces goods. This is similar to Keynes’ concept of the marginal efficiency of capital schedule being separate from the interest rate.
