COVID-19: Monetary policy in times of crisis
探讨了货币政策在新冠疫情危机中如何与财政政策互动，并分析其对主权债务可持续性的影响，强调政策制定者需考虑法律、实践和经济问题以有效应对危机。
The global pandemic has warranted swift and substantial policy responses, not least from monetary policy. This letter outlines the scope for monetary policy to react to this unprecedented crisis, in the light of the extensive fiscal policy measures introduced. We explore the interactions between monetary and fiscal policies and the consequent implications for sovereign debt sustainability. The key conclusion is that while monetary policy plays a vital role in supporting fiscal policies in the current crisis, there are important legal, practical and economic issues to consider when calibrating an effective response. This Letter argues that monetary and fiscal policies can support the economy and reinforce each other in fostering a sustainable recovery from the crisis when policymakers carefully consider and take account of these legal and economic issues.
