AbstractThis chapter introduces the reader to unconventional monetary policy, i.e. monetary policy using instruments going beyond the steering of short-term interest rates as described in the previous chapter. We start by providing the rationale of unconventional monetary policy, i.e. essentially pursuing an effective monetary policy when conventional policies are not able to provide the necessary monetary accommodation because of the zero lower bound. We then discuss negative interest rate policies, and explain why rates slightly below zero have proven to be feasible despite the existence of banknotes. We also discuss possible unintended side-effects of negative interest rates. We continue with a discussion of non-conventional credit operations: lengthening of their duration, the use of fixed-rate full allotment, the widening of the access of counterparties to the central bank’s credit operation, targeted operations, credit in foreign currency, and widening the collateral set. Finally, we turn to the purposes and effects of securities purchase programmes. We end the chapter by revisiting the classification of central bank instruments in three categories: conventional, unconventional, and lender of last resort.
