We provide a theory of the limits to monetary policy independence in open economies arising from the interaction between capital flows and domestic collateral constraints. The key feature of our theory is the existence of an 'Expansionary Lower Bound' (ELB), defined as an interest rate threshold...

The COVID-19 pandemic led many emerging market central banks to adopt, for the first time, unconventional policies in the form of asset purchase programs. In this study, we analyze the effects of these announcements on domestic financial markets using both event studies and local projections...

The COVID-19 pandemic prompted unprecedented economic stimulus worldwide. We empirically examine the impact of a withdrawal of fiscal stimulus policies on the stock markets. After constructing a database of withdrawal events, we use event study analysis and cross-country regressions to assess...

This paper investigates empirically the drivers of financial imbalances ahead of the global financial crisis. Three factors may have contributed to the build-up of financial imbalances: (i) rising global imbalances (capital flows), (ii) monetary policy that might have been too loose, (iii)...

We show that macroprudential regulation can considerably dampen the impact of globalfinancial shocks on emerging markets. More specifically, a tighter level of regulation reducesthe sensitivity of GDP growth to VIX movements and capital flow shocks. A broad set ofmacroprudential tools contribute...

Monetary policy space remains constrained by the lower bound in many countries, limitingthe policy options available to address future deflationary shocks. The existence of cashprevents central banks from cutting interest rates much below zero. In this paper, we considerthe practical feasibility...

The Global Financial Crisis has reopened discussions on the role of the monetary policy in preserving financial stability. Determining whether monetary policy affects financial variables domestically -- especially compared to the effects of macroprudential policies -- and across borders, is...

This paper analyzes the dramatic rise in U.S. inflation since 2020, which we decompose into a rise in core inflation as measured by the weighted median inflation rate and deviations of headline inflation from core. We explain the rise in core with two factors, the tightening of the labor market...
