Assessing the appropriateness of zero and negative interest rate regimes: recent developments and comparative analyses

This paper explores the widely held theoretical view that zero interest rates should result in lower borrowing costs – propelling the demand for borrowing, “the theory and practice of monetary policy”, against the practical and broader acknowledgements that further negative consequences, namely bank runs - as well as the possibility of the occurrence of concerns of banks becoming more prone to the probabilities of greater unwillingness to lend, could occur. The latter negative consequence of banks’ unwillingness to lend, being considered to arise where “banks absorb the cost of negative rates themselves” such that this phenomenon “squeezes” the profit margin between their lending and deposit rates. However, as will be illustrated, different sources and authorities on the literature agree that it is still too early to draw conclusions on the impact of negative interest rates – be it in respect of i) whether it will work, ii) its wider impact and repercussions for the economy – as well as those economies where the policy has not yet been implemented (even where the policy is on the cards – namely in jurisdictions such as the United States), as well as (iii) its impact on the behavior of individuals (households) and firms. In exploring the appropriateness of its adoption – given prevailing global financial conditions and the economic environment, the paper also contributes to the extant literature from a theoretical, practical, empirical, as well as comparative jurisdictional perspective.
