Systemic Risk Monitoring and Financial Stability

This discussion briefly outlines key elements of a systemic risk monitor to help identify risks to financial stability. The monitor distinguishes shocks, which are varied and difficult to predict, from vulnerabilities, which can amplify shocks and lead to instability. Better data and models of amplification channels, and better communication among different authorities, are needed to be effective.     

Effective Macroprudential Policy: Cross‐Sector Substitution from Price and Quantity Measures

Macroprudential policy is increasingly being implemented worldwide, and is mostly applied to banks. A key question is whether this prompts substitution toward nonbank credit. Using two different global data sets on macroprudential measures and different methodologies, including detrended series, panel estimations, and propensity score matching, we find evidence of such substitution. Substitution toward nonbank credit appears to be stronger when policy measures are binding and are implemented in economies with well‐developed nonbank credit markets. This substitution partially offsets the fall in bank credit, thus dampening the policies’ effect on total credit.     

房地产贷款中的信息不充分及其风险

房地产市场价格波动之所以能够引起银行房地产信贷损失,甚至导致金融市场和宏观经济不稳定的后果,原因是由于房地产抵押贷款中存在的测不准风险或不确定性。本文从信息不充分的视角,提出了房地产抵押贷款中的测不准风险的定义,并分析了测不准风险的特性、形成原因和特殊后果。本文认为,减少或消除不必要的不可预见和不可描述的不确定性可能是管理房地产抵押贷款违约风险,提高贷款配置效率的最好途径,这对于分析房地产市场价格波动与金融市场、宏观经济的互动关系,防止房地产价格波动对金融业和宏观经济的冲击至关重要。     

Macroprudential Policies and Housing Prices: A New Database and Empirical Evidence for Central,Eastern, and Southeastern Europe

Several countries in Central, Eastern, and Southeastern Europe used a rich set of prudential instruments during the recent credit and housing boom and bust cycles. We construct a comprehensive database of these policy measures covering 16 countries at a quarterly frequency. We use this database to investigate whether the policy measures had an impact on housing price inflation. The measures that appeared to be effective were capital measures (minimum capital adequacy ratio, maximum ratio of lending to households to share capital) and nonstandard liquidity measures (marginal reserve requirements (MRRs) on foreign funding, MRRs linked to credit growth).     

Monetary Policy and Financial Stability: Cross‐Country Evidence

We explain the heterogeneous response of central banks to financial stability risks based on a financial stability orientation (FSO) index, which reflects statutory, regulatory, and discretionary components of central banks' monetary policy frameworks. Our baseline results from a cross‐country panel of modified Taylor rules suggest that central banks with a high FSO increase their policy rates in response to elevated financial stability risks by 0.27 percentage points more than central banks with a low orientation. Back‐of‐the‐envelope calculations suggest that this policy rate differential translates into a reduced crisis probability but also into considerably lower inflation and output growth rates.     

Can We Prove a Bank Guilty of Creating Systemic Risk? A Minority Report

Because increasing a bank's capital requirement to improve the stability of the financial system imposes costs upon the bank, a regulator should ideally be able to prove beyond a reasonable doubt that banks classified as systemically risky really do create systemic risk before subjecting them to this capital punishment. Evaluating the performance of two leading systemic risk models, we show that estimation error alone prevents the reliable identification of the most systemically risky banks. We conclude that it will be a considerable challenge to develop a riskometer that is sound and reliable enough to provide an adequate foundation for macroprudential policy.     

Real Estate Prices and Corporate Investment: Theory and Evidence of Heterogeneous Effects across Firms

In this paper, we investigate the effect of real estate prices on productive investment. We build a theoretical framework of firms' investment with credit rationing and real estate collateral. We show that real estate prices affect firms' borrowing capacities through two channels. An increase in real estate prices raises the value of the firms' pledgeable assets and mitigates the agency problem characterizing the creditor–entrepreneur relationship. It simultaneously cuts the expected profit due to the increase in the cost of inputs. We test our theoretical predictions using a large French database. We do find heterogeneous effects of real estate prices on productive investment depending on the position of the firms in the sectoral distributions of real estate holdings.     

U.S. Monetary Policy and International Bond Markets

This paper analyzes how U.S. monetary policy affects the pricing of dollar‐denominated sovereign debt. We document that yields on dollar‐denominated sovereign bonds are highly responsive to U.S. monetary policy surprises—during both the conventional and unconventional policy regimes—and that the passthrough of unconventional policy to foreign bond yields is, on balance, comparable to that of conventional policy. In addition, a conventional U.S. monetary easing (tightening) leads to a significant narrowing (widening) of credit spreads on sovereign bonds issued by countries with a speculative‐grade credit rating but has no effect on the corresponding weighted average of bilateral exchange rates for a basket of currencies from the same set of risky countries; this indicates that an unanticipated tightening of U.S. monetary policy widens credit spreads on risky sovereign debt directly through the financial channel, as opposed to indirectly through the exchange rate channel. During the unconventional policy regime, yields on both investment‐ and speculative‐grade sovereign bonds move one‐to‐one with policy‐induced fluctuations in yields on comparable U.S. Treasuries. We also examine whether the response of sovereign credit spreads to US monetary policy differs between policy easings and tightenings and find no evidence of such asymmetry.     

The Housing and Credit Bubbles in the United States and Europe: A Comparison

A house price boom occurred simultaneously in the United States and in a number of European countries from 2003 to 2007, accompanied in each case by an expansion in housing finance. This article considers the role of financial innovation along with incomplete markets in these cycles.
