Recent experience with the zero lower bound on nominal interest rates, and the use of high-denomination notes by criminals and tax evaders, have led to revived proposals to phase out cash. This column argues that abolishing cash may be neither necessary nor sufficient to overcome the zero lower bound problem, and would severely undermine privacy. Allowing the public to hold reserves at central banks could reduce the need for deposit insurance, although the transition to the new regime and the effects on credit supply must be carefully considered.

The world of credit creation has shifted over recent years. This column argues this shift is more profound than is commonly understood. It describes the private credit creation process, explains how the ‘money multiplier’ depends upon inter-bank trust, and discusses the implications for monetary policy.

Are central banks printing vast quantities of money? This column explains how money-multiplier economics (central banks create reserves that allow commercial banks to create money) no longer holds. Today, non-bank financial institutions play a pivotal role in money/liquidity creation, but hold no reserves. Their lending depends on “private reserves”, mainly highly liquid government securities. Creating more ‘public’ reserves by buying such ‘private’ reserves doesn’t trigger money creation – it just substitutes among reserve types. Open-market purchases only create money if they swap a monetary base for assets that are no longer accepted at full value as collateral in the market.
