Macro-Prudential Policies to Mitigate Financial System Vulnerabilities
Macro-prudential policies aimed at mitigating systemic financial risks have become part of the policy toolkit in many emerging markets and some advanced countries. Their effectiveness and efficacy are not well-known, however. Using panel data regressions, we analyze how changes in balance sheets of some 2,800 banks in 48 countries over 2000–2010 respond to specific macro-prudential policies. Controlling for endogeneity, we find that measures aimed at borrowers––caps on debt-to-income and loan-to-value ratios––and at financial institutions––limits on credit growth and foreign currency lending––are effective in reducing asset growth. Countercyclical buffers are little effective through the cycle, and some measures are even counterproductive during downswings, serving to aggravate declines, consistent with the ex-ante nature of macro-prudential tools.
Monetary Policy and Balance Sheets
This paper evaluates the strength of the balance sheet channel in the U.S. monetary policy transmission mechanism over the past three decades. Using a Factor-Augmented Vector Autoregression model on an expanded data set, including sectoral balance sheet variables, we show that the balance sheets of various economic agents act as important links in the monetary policy transmission mechanism. Balance sheets of financial intermediaries, such as commercial banks, asset-backed-security issuers and, to a lesser extent, security brokers and dealers, shrink in response to monetary tightening, while money market fund assets grow. The balance sheet effects are comparable in magnitude to the traditional interest rate channel. However, their economic significance in the run-up to the recent financial crisis was small. Large increases in interest rates would have been needed to avert a rapid rise of house prices and an unsustainable expansion of mortgage credit, suggesting an important role for macroprudential policies.
Fiscal Consolidation and the Cost of Credit
We examine how the cost of corporate credit varies around fiscal consolidations aimed at reducing government debt. Using a new dataset on fiscal consolidations and syndicated corporate loan data, we find that loan spreads increase with fiscal consolidations, especially for small firms, domestic firms, and for firms with limited alternative financing sources. These adverse effects are mitigated substantially if consolidations are large, and can be avoided if consolidations are also accompanied with more adaptable macroeconomic policies and implemented by a stable government. These findings suggest that lenders price the short-term recessionary effects in loans but large consolidations can reduce or undo the increase in spreads, especially under favorable country conditions, by signaling credibility and creating expansionary expectations.
Policies for Macrofinancial Stability
This note explores the costs and benefits of different policy options to reduce the risks associated with credit booms, drawing upon several country experiences and the findings from econometric analysis.
Effects of Macroprudential Policy: Evidence from Over 6,000 Estimates
This paper builds a novel database on the effects of macroprudential policy drawing from 58 empirical studies, comprising over 6,000 results on a wide range of instruments and outcome variables. It encompasses information on statistical significance, standardized magnitudes, and other characteristics of the estimates. Using meta-analysis techniques, the paper estimates average effects to find i) statistically significant effects on credit, but with considerable heterogeneity across instruments; ii) weaker and more imprecise effects on house prices; iii) quantitatively stronger effects in emerging markets and among studies using micro-level data; and iii) statistically significant evidence of leakages and spillovers. Other findings include relatively stronger impacts for tightening than loosening actions and negative effects on economic activity in the near term.
The Regulatory Responses to the Global Financial Crisis
We identify current challenges for creating stable, yet efficient financial systems using lessons from recent and past crises. Reforms need to start from three tenets: adopting a system-wide perspective explicitly aimed at addressing market failures; understanding and incorporating into regulations agents’ incentives so as to align them better with societies’ goals; and acknowledging that risks of crises will always remain, in part due to (unknown) unknowns – be they tipping points, fault lines, or spillovers. Corresponding to these three tenets, specific areas for further reforms are identified. Policy makers need to resist, however, fine-tuning regulations: a “do not harm” approach is often preferable. And as risks will remain, crisis management needs to be made an integral part of system design, not relegated to improvisation after the fact.
Macroprudential Policies in Southeastern Europe
This paper presents a detailed account of the rich set of macroprudential measures taken in four Southeastern European countries—Bulgaria, Croatia, Romania, and Serbia—during their synchronized boom and bust cycles in 2003–12, and assesses their effectiveness. We find that only strong measures helped contain domestic credit growth, the share of foreigncurrency- denominated loans provided by the domestic banking sector, or the domestic banking sector’s reliance on foreign borrowing during the boom years. We also find that circumvention via direct external borrowing often fully offset the effectiveness of these strict measures, and thatmeasures taken during the bust had no discernible impact. We conclude that (i) proper calibration of macroprudential measures is of the essence; (ii) only strong, broad-based macroprudential measures can contain credit booms; (iii) econometric studies of macroprudential policy effectiveness should focus on measures rather than on instruments (i.e. classes of measures) and in so doing allow for possible non-linear and state-contingent effects.
World Economic Outlook, October 2021
The global recovery continues but the momentum has weakened, hobbled by the pandemic. Fueled by the highly transmissible Delta variant, the recorded global COVID-19 death toll has risen close to 5 million and health risks abound, holding back a full return to normalcy. Pandemic outbreaks in critical links of global supply chains have resulted in longer-than-expected supply disruptions, further feeding inflation in many countries. Overall, risks to economic prospects have increased, and policy trade-offs have become more complex.
Macroprudential Policies, Economic Growth, and Banking Crises
Using a sample that covers more than 100 countries over the 2000-2017 period, we assess the impact of macroprudential policies on financial stability. In particular, we examine whether the activation of macroprudential policies is conducive to a lower incidence of systemic banking crises. Our empirical setup is designed to account for the potential direct and indirect effects that macroprudential policies can have on banking crises. We find that while macro-prudential policies exert a direct stabilizing effect, they also have an indirect destabilizing effect, which works through the depressing of economic growth. A Generalized Impulse Response Function analysis of a dynamic system composed of the probability of a banking crisis and economic growth reveals, however, that macroprudential policies have a positive net effect on financial stability (lower likelihood of systemic banking crises).
