This study examines the effectiveness of unconventional monetary policies (UMP). It considers whether these policies have been successful and where their effects remain uncertain. We survey both the domestic financial market and macro‐economic effects of UMP in the economies where these policies were introduced and their international spillover effects. The paper considers the impact of a wide range of UMP rather than the effects of specific policy instruments. We also provide a retrospective on the important case of Japan beginning in the late1990s and ask whether the Eurozone's experience with UMP is substantively different given its structure of policymaking. Finally, we ask: if the ‘old normal’ is not in our future, should the ‘new normal’ in monetary policy routinely include what we now refer to as UMP? We conclude that UMP can prevent economic collapse but are not designed to promote stronger long‐term economic growth. Apart from new communication strategies, the use of UMP under normal circumstances does not appear to be a sound monetary policy strategy. Failure to learn this lesson might also enable future policy makers to ask or expect too much from their central banks.

The zero lower bound (ZLB) may restrict the responsiveness of exchange rates to news. A proxy for central bank communication is added as a determinant in a model of exchange rate movements. Two reserve currencies, the British pound and euro, and two currencies of small open economies, the Canadian dollar and Swedish krona, are examined. Reserve currencies are more vulnerable to the ZLB constraint, while the currencies of small open economies become more responsive to foreign central bank announcements. Certain unconventional monetary policy announcements were found to significantly impact exchange rates at the ZLB.

This paper provides both theoretical and empirical evidence that maintains that a central bank's organizational structure, culture and learning system are important for achieving best governance practices in emerging market economies. It argues that a central bank's organizational structure and culture facilitate the effective implementation of governance practices that have been enacted by law or in a strategic plan, with specific reference to central bank independence, communication, transparency, professionalization, technical excellence and reputation risk management. Qualitative interviews and a review of the bank's primary documents showed that the progress made by the Bank al‐Maghrib over the last two decades in establishing best governance practices in policies and legal statutes is, to a significant extent, being matched by reforms to its internal processes, but there remains room for improvement.

Empirical evidence on the potential impact of central bank policies on government bond yields at the effective lower bound (ELB) is presented for nine economies. We quantify the content of central bank communications and consider international policy spillovers. Yields at the medium‐to‐longer end of the yield curve remain responsive to news for a few years after the ELB is reached. Yields become more sensitive to the content central bank communication at the ELB. Our results provide further evidence that central bank communication is an important element of monetary policy making when the interest rate tool loses efficacy. (JEL E52, E58, G12, F42)
