The impact of macroprudential policies in Latin America: An empirical analysis using credit registry data

This paper summarises the results of a joint research project by five central banks in Latin America countries (Argentina, Brazil, Colombia, Mexico and Peru) to evaluate the effectiveness of macroprudential tools and their interaction with monetary policy. Using meta-analysis techniques, we summarise the results of a common empirical framework based on confidential bank-loan data. The main conclusions are that (i) macroprudential policies have been quite effective in stabilising credit cycles. The propagation of the effects to credit growth is more rapid for policies aimed at curbing the cycle than for policies aimed at fostering resilience; and (ii) macroprudential tools have a greater effect on credit growth when reinforced by the use of monetary policy.     

Optimal Macroprudential Policies and House Prices in Korea

This article investigates the impacts of the macroprudential policy of limitation on credit growth in housing market on Korean economy to find empirical and theoretical implications. Empirical results based on VAR models show that macroprudential policies like LTV and DTI in Korea have significant and persistent effect on real household credit and real house price. This article further addresses implications of optimal macroprudential and monetary policy in Korea by employing a standard DSGE model. The results suggest that the time-varying macroprudential policy responding to the borrower’s debt to income ratio is most effective in stabilizing household debt among the macroprudential policy rules considered, but produces a moderate downturn of the economy.     

Political Stability and the Effectiveness of Currency Based Macro Prudential Measures

The use of multiple currency based macroprudential tools by Reserve Bank of India, India’s central bank, has helped create resilience in the economy, especially during financial turmoil. However, in a democratic set-up like India, the analysis of capital based macroprudential reforms needs to incorporate the political stability, as there is increasing evidence that macroprudential policy effectiveness is closely linked to political conditions. This study incorporates the role of political stability is understanding the effectiveness of currency based macroprudential policies, by using the years of election as a proxy for political uncertainty. I develop an index of capital based macroprudential policies (CMPP) using the notifications on capital flows and risk management guidelines on foreign exchange exposures from Reserve Bank of India. Using a GARCH model, the impact of CMPP on the net capital inflows is analyzed for the period from January, 1997 to March, 2018. I find that while the presence of CMPP leads to a fall in capital flow volatility, such policies in the years of election are ineffective in curbing capital flow volatility. The paper adds to the increasing evidence coming in recent years of the link between political cycles, interest groups and macroprudential policies.

     

对货币政策和宏观审慎政策双支柱调控框架内在逻辑的思考

本轮国际金融危机以来,金融稳定在中央银行政策目标中的重要性再次得到强化。随着具有顺周期波动特征的金融市场和金融资产规模显著增大,金融管理政策需要更加关注金融稳定和系统性风险问题,货币稳定和金融稳定“双目标”的重要性凸显出来。政策目标的变化相应要求优化和完善政策工具箱,需要健全宏观审慎政策框架作为应对系统性风险的工具,并与货币政策相互配合,形成由货币政策和宏观审慎政策“双支柱”支撑起“双目标”的基本框架,共同维护好货币稳定和金融稳定。在此框架中,货币政策和宏观审慎政策都不可或缺,须相互补充,形成合力,产生“一加一大于二”的政策效应增进效果。健全货币政策和宏观审慎政策双支柱调控框架,有利于把经济周期和金融周期更好地结合起来,把维护经济稳定与促进金融稳定更好地结合起来。下一阶段应进一步健全宏观审慎政策框架,并完善货币政策和宏观审慎政策协调配合的体制机制。     

Evaluating the impact of macroprudential policies on credit growth in Colombia

The purpose of this paper is to evaluate the effectiveness of two macroprudential policies in Colombia: marginal reserve requirements and dynamic provisions. The first measure was implemented to control excessive credit growth, while the latter was designed to increase systemic resilience by establishing a countercyclical buffer through loan loss provision requirements. To perform this analysis, a rich dataset based on loan-by-loan information for Colombian banks during the 2006–2009 period is used. Our identification strategy closely follows Khwaja & Mian (2008), so that only those observations with multiple banking relations are considered. Estimations are performed applying firm and firm-time fixed effects to control for demand factors, thus appropriately isolating loan demand from credit supply. Results from the econometric model suggest that dynamic provisions, the countercyclical reserve requirement and an aggregate measure of the macroprudential policy stance had a negative effect on credit growth, which varies according to bank and debtor-specific characteristics. Particularly, effects are intensified for riskier debtors, suggesting that the aggregate macroprudential policy stance in Colombia has worked effectively to stabilize credit cycles and reduce risk-taking.     

Credit cycle coherence in the eurozone: Was there a euro effect?

This paper examines effects of the euro introduction on credit cycle coherence in the eurozone through six channels. We construct and describe credit cycles for total bank credit, household mortgages and non-financial business loans for 16 EMU economies over 1990–2015. Credit cycle coherence is measured by synchronicity of cycle movements and similarity of their amplitudes. We find that the effect of euro introduction runs through elimination of currency risk and higher capital flows, which decrease coherence of total credit and mortgage credit cycles, but increase coherence of business credit cycles. Falling interest rates contribute to the convergence of total and mortgage credit cycles. Financial deregulation and legal harmonization are associated with lower coherence of all credit cycles, while trade openness has the opposite impact. The findings impinge on monetary policy effectiveness in the eurozone, with implications for macroprudential policy.     

The use and effectiveness of macroprudential policies: New evidence

Using a recent IMF survey and expanding on previous studies, we document the use of macroprudential policies for 119 countries over the 2000–2013 period, covering many instruments. Emerging economies use macroprudential policies most frequently; especially foreign exchange related ones while advanced countries use borrower-based policies more. Usage is generally associated with lower growth in credit, notably in household credit. Effects are less in financially more developed and open economies, however, and usage comes with greater cross-border borrowing, suggesting some avoidance. And while macroprudential policies can help manage financial cycles, they work less well in busts.     

中国金融周期与横向关联:时空双维度相结合视角

宏观审慎政策关注各金融子市场在时间维度上的金融周期和空间维度上的横向关联。本文结合时间维度与空间维度视角,使用股票市场、货币市场、房地产市场以及信贷市场的数据,测算2001—2019年中国金融周期和横向关联的波动特征、作用关系与频域叠加机理。研究结果表明:时间维度金融周期与空间维度横向关联的波动趋势具有一致性。我国金融周期长度约为10.33年,横向关联波动周期的长度约为10.58年。从作用关系上看,首先,我国房地产周期达到波峰后,会对股票市场和信贷市场产生较强的溢出效应。随后,股市周期达到波峰后,会向房地产市场和信贷市场产生较强的溢出效应。最后,我国信贷市场接受股票市场和房地产市场溢出后,信贷周期会逐渐达到波峰。从频域叠加机理的角度看,我国金融子市场间横向关联的波动主要由中低频波段驱动,中低频波段横向关联的持续期在2个月以上。     

货币政策与宏观审慎政策的协调

本文在梳理学术文献和国际经验基础上,讨论了货币政策与宏观审慎政策之间的潜在冲突和协调机制。国际文献的初步结论是,为了同时实现价格稳定和金融稳定目标,大部分情况下需要货币政策与宏观审慎政策反向操作(由于政策的替代性),但有时也需要两者同向操作(由于政策的互补性),最优政策组合取决于宏观冲击的类别和风险的来源。本文认为,选择最优组合是一个复杂的理论和实证问题,除了冲击类别和风险来源外,不同的金融体制和经济周期阶段也会影响选择结果。因此,货币政策当局与宏观审慎当局之间需要建立有效的协调机制,并加强对货币政策和宏观审慎政策“溢出效应”的分析能力。基于上述理论,针对我国“双支柱”决策的现状和问题提出如下改革建议:一是从法律上明确中央银行的金融稳定职责。二是建立在同一框架内分析货币政策与宏观审慎政策的方法和工具。三是将金融监管部门的主要宏观审慎政策决策权集中至中央银行。四是建立货币政策与宏观审慎政策的协调流程与机制。     

Optimal macroprudential policy and rational bubbles

We provide a microfounded framework for the welfare analysis of macroprudential policy within a model of rational bubbles. For this, we posit an overlapping generation model where productivity and credit supply are subject to random shocks. We find that when real interest rates are lower than the rate of growth, credit financed bubbles may be welfare improving because of their role as a buffer in channeling excessive credit supply and inefficient investment at the firms’ level, but their sudden price decrease may cause a systemic crisis. Therefore, a well designed macroprudential policy plays a key role in improving efficiency while preserving financial stability. Our theoretical framework allows us to compare the efficiency of alternative macroprudential policies. Contrarily to conventional wisdom, we show that macroprudential policy (i) may be efficient even in the absence of systemic risk, (ii) has to be contingent on productivity shocks and (iii) must be contingent upon the level of real interest rates.     

Managing price and financial stability objectives in inflation targeting economies in Asia and the Pacific

Many central banks have adopted explicit objectives for financial stability, raising the possibility of trade-offs between price and financial stability objectives. Based on structural vector autoregressions that incorporate both monetary and macroprudential policy shocks for four inflation targeting economies in Asia and the Pacific, we analyse the role of each policy shock in explaining deviations from the other policy’s objective, by applying historical decompositions. The macroprudential measures used in the study affect credit extended to the private sector. We find that there are periods when macroprudential policy shocks have contributed to pushing inflation away from the central bank’s inflation target and when monetary policy shocks have contributed to buoyant credit, suggesting that there have been short-term trade-offs between price and financial stability objectives. However, we also find periods when macroprudential policy shocks helped stabilise inflation and monetary policy shocks contributed to financial stability.     

Rapid Credit Growth in Emerging Markets: Boon or Boom-Bust?

Episodes of rapid credit growth, especially credit booms, tend to end abruptly, typically in the form of financial crises. This paper presents the findings of a comprehensive event study focusing on sixty credit booms across emerging markets. The build-up of credit booms across emerging markets seems to be characterized by loose monetary policy stances, with domestic policy rates below trend during the prepeak phase of credit booms. While credit booms are associated with episodes of large capital inflows, international interest rates (a proxy for global liquidity) are virtually flat during these periods. Therefore, although external factors such as global liquidity conditions matter, and possibly increasingly so over time, domestic factors (especially monetary policy) also appear to be tightly associated with real credit growth across emerging markets.     

Macroprudential policy in the EU: A political economy perspective

In response to the lessons of the global financial crisis, macroprudential policy is now firmly established as a financial policy area to prevent excessive risk taking in the financial sector and mitigate its effects on the real economy. However, macroprudential policy is facing several challenges relating to its political sensitivity and institutional context. These include political and interest group resistance, weaknesses in the governance framework, and limited institutional memory among policy makers. This article seeks to contribute to the contextual understanding of macroprudential policy by exploring how factors relating to these challenges influence policy in the EU. More specifically, it develops and empirically tests a number of hypotheses on how wider institutional and structural factors influence the actual use of macroprudential measures across Europe. The findings yield considerable support for theoretical predictions that institutions and contexts matter - Political pressure and interest group resistance tend to influence the intensity of macroprudential policy stances. Weaker policy stances characterise countries where banking systems depend on domestic banks, whereas the opposite holds for financial systems with significant market shares of other financial intermediaries. Results on institutional arrangements show that governance arrangements on relating to transparency influence policy stances. The results also indicate that policy makers' inertia is best counteracted by appointing a single macroprudential authority. The results differ somewhat depending on whether countries are based in the Euro zone or not. This suggests that policy frameworks that are multi-layered and complex pose tricky conundrums on how to ensure sufficient institutional autonomy, policy capacity and discretion among macroprudential authorities. This also has implications on other policy areas macroprudential policy, such as microprudential policy, crisis management and fiscal policy.     

宏观审慎政策工具的有效性检验——基于对114家商业银行的实证分析

本文基于国际货币基金组织调查数据库构建中国宏观审慎政策工具综合指标,同时选取存款准备金率和贷款价值比上限代表宏观审慎政策工具,检验宏观审慎政策工具的有效性.通过对2008—2018年间我国114家商业银行的实证检验发现,无论是单一宏观审慎政策工具,还是宏观审慎工具综合指标,均能抑制信贷规模以及房价的快速增长,减少系统性风险的积累;且针对特定目标设立的宏观审慎政策工具的政策效果更为显著.进一步研究发现,宏观审慎政策工具在微观层面也能有效抑制银行风险.就具体的政策效果而言,相较于国有银行和股份制银行,规模较小的城商行和农商行对宏观审慎政策工具的反应更为敏感.     

The countercyclical capital buffer and the composition of bank lending

Do targeted macroprudential measures impact non-targeted sectors too? We investigate the compositional changes in the supply of credit by Swiss banks, exploiting their differential exposure to the activation in 2013 of the countercyclical capital buffer (CCyB) which targeted banks’ exposure to residential mortgages. We find that the additional capital requirements resulting from the activation of the CCyB are associated with higher growth in banks’ commercial lending. While banks are lending more to all types of businesses, the new macroprudential policy benefits smaller and riskier businesses the most. However, the interest rates and other costs of obtaining credit for these firms rise as well.     

Heterogeneous effects of macroprudential policies on firm leverage and value

We empirically investigate the effect of financial institution-targeted macroprudential policies on firms using a comprehensive macroprudential policy dataset and corporate panel data across 35 countries. We find that tightening of macroprudential measures persistently curbs the leverage of firms, while loosening is related to the increase in leverage. We also find that this effect on leverage is heterogeneous across firms, as net macroprudential policy actions reduce the procyclicality of leverage more significantly for small firms and firms with high leverage. Also, we estimate the effect of macroprudential policies on firm value to evaluate potential policy trade-offs as the policies restrict the firms' access to credit during economic booms while protecting them from future financial crises. The effect of macroprudential policies on firm value is generally positive despite the policies' restrictive nature. Further, the effect on firm value is heterogeneous depending on firm characteristics: the positive effect becomes stronger as firms are less leveraged, but this positive effect is weaker for firms that grow faster, suggesting potential costs of macroprudential policies for these firms.     

亚洲新兴经济体国际资本流动驱动因素研究——基于GMM模型的实证分析

理解资本流入的驱动因素,对于设计一个有效的资本流动管理政策框架至关重要。本文研究了1998年至2018年间45个新兴经济体面临的各类资本流动的驱动因素,重点分析了资本流向亚洲地区的驱动因素与其他地区的共性和异质性。使用广义矩估计方法(GMM)对面板数据集的实证结果表明,对新兴经济体而言,制度质量和国内因素对吸引资本流入具有重要影响;对亚洲地区来说,人均收入增长和贸易开放是吸引资本流入的重要驱动因素,国内外利差水平和实际有效汇率变动对吸引组合投资和其他投资具有显著影响,VIX指数和影子利率对亚洲新兴经济体资本流动规模的影响也具有重要影响。这表明,在设计管理资本流入的政策框架时,全球经济金融合作和政策协调应被考虑在内。     

Macroprudential measures and developments in bank funding costs

In this paper, we study how the use of macroprudential policy instruments is associated with bank funding costs. To accomplish this, we develop several macroprudential indices based on policy objectives and include different macroeconomic and bank-level variables, while we also separately analyse the cost of debt and overall cost of funding. Our analysis relies on bank-level data in 43 European countries for the period between 2000 and 2017, and a macroprudential policy dataset based on an IMF survey. The results show the activation of macroprudential policies is chiefly related with lower bank funding costs, with this association being stronger for developed countries than emerging ones. The results also reveal positive links with certain macroprudential measures to bank cost of funding, offering further insight into the repercussions of calibrating and selecting macroprudential tools.     

Effects of Monetary and Macroprudential Policies—Evidence from Four Inflation Targeting Economies

We examine the effects of monetary and macroprudential policies in the Asia‐Pacific region, where many inflation targeting economies have adopted macroprudential policies in order to safeguard financial stability. Using structural panel vector autoregressions that identify both monetary and macroprudential policy actions, we show that tighter macroprudential policies used to contain credit growth also have a significant negative impact on macroeconomic aggregates such as real GDP and the price level. The similar effects of monetary and macroprudential policies may suggest a complementary use of the two policies at normal times. However, they could also create challenges for policymakers, especially during times when low inflation coincides with buoyant credit growth.     

Macroprudential policy and imbalances in the euro area

Since its creation the euro area suffered from imbalances between its core and peripheral members. This paper checks whether macroprudential policy applied to the peripheral countries could contribute to providing more macroeconomic stability in this region. To this end we build a two-economy macrofinancial model and simulate the effects of macroprudential policy (regulating the loan-to-value ratio) when the core and the periphery are exposed to asymmetric shocks. We find that macroprudential policy is able to substantially lower the amplitude of credit and output fluctuations in the periphery. However, for the policy to be effective, it should be decentralized. Very similar conclusions hold when welfare is considered as the optimality criterion.
