International Evidence on the Use and Effectiveness of Macroprudential Policies
In recent years, policymakers in advanced and emerging economies have employed a variety of macroprudential policy tools?targeted rules or requirements that enhance the stability of the financial system as a whole by addressing the interconnectedness of individual financial institutions and their common exposure to economic risk factors. To examine the foreign experience with these tools, we constructed a novel macroprudential policy (MAPP) index. This index allows us to quantify the effects of these policies on bank credit and house prices, two variables that are often the target of ...

Revisiting the Case for International Policy Coordination
Prompted by the U.S. financial crisis and subsequent global recession, policymakers in advanced economies slashed interest rates dramatically, hitting the zero lower bound (ZLB), and then implemented unconventional policies such as large-scale asset purchases. In emerging economies, however, the policy response was more subdued since they were less affected by the financial crisis. As a result, capital flows from advanced to emerging economies increased markedly in response to widening interest rate differentials. Some emerging economies reacted by adopting measures to slow down capital ...

Credit spreads, financial crises, and macroprudential policy
Credit spreads display occasional spikes and are more strongly countercyclical in times of financial stress. Financial crises are extreme cases of this nonlinear behavior, featuring skyrocketing credit spreads, sharp losses in bank equity, and deep recessions. We develop a macroeconomic model with a banking sector in which banks? leverage constraints are occasionally binding and equity issuance is endogenous. The model captures the nonlinearities in the data and produces quantitatively realistic crises. Precautionary equity issuance makes crises infrequent but does not prevent them ...

Exchange rate dynamics and monetary spillovers with imperfect financial markets
We use a two-country New Keynesian model with financial frictions and dollar debt in balance sheets to investigate the foreign effects of U.S. monetary policy. Financial amplification works through an endogenous deviation from uncovered interest parity (UIP) arising from limits to arbitrage in private intermediation. Combined with dollar trade invoicing, this mechanism leads to large spillovers from U.S. policy, consistent with the evidence. Foreign monetary policies that attempt to stabilize the exchange rate reduce welfare and may exacerbate exchange rate volatility. We document empirically ...

Financial Crises and the Desirability of Macroprudential Policy
The global financial crisis has put financial stability risks?and the potential role of macroprudential policies in addressing them?at the forefront of policy debates. The challenge for macroeconomists is to develop new models that are consistent with the data while being able to capture the highly nonlinear nature of crisis episodes. In this post, we evaluate the impact of a macroprudential policy that has the government tilt incentives for banks to encourage them to build up their equity positions. The government has a role since individual banks do not internalize the systemic benefit of ...

Good News, Leverage, and Sudden Stops
One of the major debates in open economy macroeconomics is the extent to which capital inflows are beneficial for growth. In principle, these flows allow countries to increase their consumption and investment spending beyond their income by enabling them to tap into foreign saving. Periods of such borrowing, however, are associated with large trade deficits, external debt accumulation, and, in some cases, overheating when these economies operate beyond their potential output level for an extended period of time. The relevant question in this context is whether the rate at which a country is ...

Modeling the Global Effects of the COVID-19 Sudden Stop in Capital Flows
The COVID-19 outbreak has triggered unusually fast outflows of dollar funding from emerging market economies (EMEs). These outflows are known as “sudden stop” episodes, and they are typically followed by economic contractions. In this post, we assess the macroeconomic effects of the COVID-induced sudden stop of capital flows to EMEs, using our open-economy DSGE model. Unlike existing frameworks, such as the Federal Reserve Board’s SIGMA model, our model features both domestic and international financial constraints, making it well-suited to capture the effects of an outflow of ...

Good news is bad news: leverage cycles and sudden stops
We show that a model with imperfectly forecastable changes in future productivity and an occasionally binding collateral constraint can match a set of stylized facts about ?sudden stop? events. ?Good? news about future productivity raises leverage during times of expansion, increasing the probability that the constraint binds, and a sudden stop occurs, in future periods. The economy exhibits a boom period in the run-up to the sudden stop, with output, consumption, and investment all above trend, consistent with the data. During the sudden stop, the nonlinear effects of the constraint induce ...

How Effective are Macroprudential Policies? An Empirical Investigation
In recent years, policymakers have generally relied on macroprudential policies to address financial stability concerns. However, our understanding of these policies and their efficacy is limited. In this paper, we construct a novel index of domestic macroprudential policies in 57 advanced and emerging economies covering the period from 2000:Q1 to 2013:Q4, with tightenings and easings recorded separately. The effectiveness of these policies in curbing bank credit growth and house price inflation is then assessed using a dynamic panel data model. The main findings of the paper are: (1) ...
