The Macroprudential Framework; Policy Responsiveness and Institutional Arrangements

This paper gauges if, and how, institutional arrangements are correlated with the use of macroprudential policy instruments. Using data from 39 countries, the paper evaluates policy response time in various types of institutional arrangements for macroprudential policy and finds that the macroprudential framework that gives the central bank an important role is associated with more timely use of macroprudential policy instruments. Policymakers may also tend to use macroprudential instruments more quickly if the ability to conduct monetary policy is somehow constrained. This finding points to the importance of coordination between macroprudential and monetary policy.

Evaluating the Net Benefits of Macroprudential Policy; A Cookbook

The paper proposes a simple, new, analytical framework for assessing the cost and benefits of macroprudential policies. It proposes a measure of net benefits in terms of parameters that can be estimated: the probability of crisis, the loss in output given crisis, policy effectiveness in bringing down both the probability and damage during crisis, and the output-cost of a policy decision. It discusses three types of policy leakages and identifies instruments that could best minimize the leakages. Some rules of thumb for policymakers are provided.

With Great Power Comes Great Responsibility: Macroprudential Tools at Work in Canada

The goal of this paper is to assess the effectiveness of the policy measures taken by Canadian authorities to address the housing boom. We find that the the last three rounds of macroprudential policies implemented since 2010 were associated with lower mortgage credit growth and house price growth. The international experience suggests that - in addition to tighter loan-to-value limits and shorter amortization periods - lower caps on the debt-to-income ratio and higher risk weights could be effective if the housing boom were to reignite. Over the medium term, the authorities could consider structural measures to further improve the soundness of housing finance.

Financial and Business Cycles in Brazil

This paper explores the nexus between the financial cycle and business cycle in Brazil. Cycles are estimated using a variety of commonly-used statistical methods and with a small, semistructural model of the Brazilian economy. An advantage of using the model-based approach is that financial and business cycles can be jointly estimated, allowing information from all key economic relationships to be used in a consistent way. The results show that Brazil is now in the downturn phase of the financial cycle. Moreover, the results underscore the importance of macro-financial linkages and highlight risks to the recovery going forward.

Investment in Brazil: From Crisis to Recovery

While Brazil’s deep recession has been broad based, it has been marked by a particularly large fall in investment. Real investment fell by around 30 percent between the beginning of 2014 and the beginning of 2017. This paper finds that a variety of factors contributed to the investment decline, including a deterioration in Brazil’s medium-term growth prospects, rising real interest rates, falling terms of trade, rising uncertainty related to economic policy, rising levels of corporate leverage and lower cash flow. Some of the factors that have weighed on investment over recent years have begun to normalize providing some impetus for a recovery. However, still-high levels of corporate leverage and the prospect of continued uncertainty related to economic policy settings suggest a turnaround in investment is likely to be subdued.

Towards Macroprudential Stress Testing : Incorporating Macro-Feedback Effects

Macro-feedback effects have been identified as a key missing element for more effective macro-prudential stress testing. To fill this gap, this paper develops a framework that facilitates the analysis of both the direct effects of macroeconomic shocks on the solvency of individual banks and feedback effects that allow for the amplification and propagation of shocks that can result from bank deleveraging and credit crunches. The framework ensures consistency in the key relationships between macroeconomic and financial variables, and banks’ balance sheets. This is accomplished by embedding a standard stress-testing framework based on individual banks’ data in a semi-structural macroeconomic model. The framework has numerous applications that can strengthen stress testing and macro financial analysis. Moreover, it provides an avenue for many extensions that address the challenges of incorporating other second-round effects important for comprehensive systemic risk analysis, such as interactions between solvency, liquidity and contagion risks. To this end, the paper presents some preliminary simulations of feedback effects arising from the link between the liquidity and solvency risk.
