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.     

Countercyclical Bank Capital Requirement and Optimized Monetary Policy Rules

Using BoC-GEM-Fin, a large-scale dynamic stochastic general equilibrium (DSGE) model with real, nominal, and financial frictions featuring a banking sector, we explore the macroeconomic implications of various types of countercyclical bank capital regulations. Results suggest that countercyclical capital requirements have a significant stabilizing effect on key macroeconomic variables, but mostly after financial shocks. Moreover, the bank capital regulatory policy and monetary policy interact, and this interaction is contingent on the type of shocks that drive the economic cycle. Finally, we analyze loss functions based on macroeconomic and financial variables to arrive at an optimal countercyclical regulatory policy in a class of simple implementable Taylor-type rules. Compared to bank capital regulatory policy, monetary policy is able to stabilize the economy more efficiently after real shocks. On the other hand, financial shocks require the regulator to be more aggressive in loosening/tightening capital requirements for banks, even as monetary policy works to counter the deviations of inflation from the target.     

Macroprudential policy transmission and interaction with fiscal and monetary policy in an emerging economy: a DSGE model for Brazil

We investigate the transmission of macroprudential (MaP) instruments in a dynamic stochastic general equilibrium model where foreign capital flows interact with financial frictions and banks are exposed to different sources of credit default risk. The model is estimated for Brazil with Bayesian techniques. We compute optimal combinations of simple MaP, fiscal and monetary policy rules that can react to the business and/or the financial cycle. We find that the gains from implementing a cyclical fiscal policy are only significant if MaP policy countercyclically reacts to the financial cycle. Optimal fiscal policy is countercyclical in the business cycle.     

Monetary policy and macroprudential policy: Rivals or teammates?

This paper sheds some light on situations in which monetary and macroprudential policies may interact (and potentially get into conflict) and contributes to the discussion about the coordination of those policies. Using data for the Czech Republic and five euro area countries we show that monetary tightening has a negative impact on the credit-to-GDP ratio and the non-risk-weighted bank capital ratio (i.e. a positive impact on bank leverage), while these effects have strengthened considerably since mid-2011. This supports the view that accommodative monetary policy contributes to a build-up of financial vulnerabilities, i.e. it boosts the credit cycle. On the other hand, the effect of the higher bank capital ratio is associated with some degree of uncertainty. For these and other reasons, coordination of the two policies is necessary to avoid an undesirable policy mix preventing effective achievement of the main objectives in the two policy areas.     

房价波动、金融稳定与最优宏观审慎政策

本文通过构建包含家庭住房抵押借款摩擦和银行贷款摩擦的动态随机一般均衡模型,重点考察了异质性冲击下房价波动对金融稳定的影响。研究发现,房价上涨会导致银行风险溢价及杠杆率显著上升,进而加剧金融体系的内在不稳定。为降低房价波动及维护金融稳定,选取两类宏观审慎政策工具进行逆周期调控实验,结果表明,在住房需求冲击下,金融管理部门应选取贷款价值比政策,且应对房贷积极调控,而对房价进行中性调控。在最终产品部门生产率冲击、房地产部门生产率冲击及跨期偏好冲击下,应选取资本充足率政策,但对房贷和房价调控力度的把握则存在差异。本研究为厘清房价波动对金融稳定的动态传导机制,以及金融管理部门如何选取宏观审慎政策工具以稳定房价并降低系统性金融风险提供了启示。

本文在两国模型的DSGE框架下引入宏观审慎政策监管机制,把金融摩擦、国际资本流动和宏观审慎政策纳入同一个一般均衡分析框架。通过国际贸易和国际资本流动机制,考察宏观审慎政策的国际影响机制。基于我国的模拟分析结果表明,第一,对于我国来说,宏观审慎政策的国际合作不仅能够有效地应对国内经济冲击,也有助于抵御外部经济冲击。第二,我国推动构建国际宏观审慎政策长效合作机制,有助于积极应对国际资本流动,促进我国资本市场进一步开放。第三,我国宏观审慎政策存在国际溢出效应,但是对其他国家的影响并不明显。     

International spillovers of monetary policy: Lessons from Chile,Korea, and Poland

In this paper, we assess evidence on international monetary policy spillovers to domestic bank lending in Chile, Korea, and Poland, using confidential bank-level data and different measures of monetary policy shocks in relevant currency areas. These three emerging market economies are small and open, their banking systems do not have significant presence overseas, and they can be considered as price takers in the world economy. Such features allow for better identification of binding financial constraints and foreign monetary policy shocks. We find that the monetary policy shocks spill over into domestic bank lending, modifying the degree to which financial frictions tighten or relax, and this evidence is consistent with international bank lending and portfolio channels.     

The nexus of macroprudential supervision,monetary policy,and financial stability

I discuss changes to bank supervision and regulation since the financial crisis. Microprudential supervision promotes the safety and soundness of individual institutions, while macroprudential supervision focuses on emerging risks to financial system stability. I highlight tools for implementing this macroprudential approach to promoting financial stability, and discuss the interactions and proper relationship between monetary policy and financial stability. While macroprudential tools should be the first line of defense against emerging financial imbalances, in cases where those tools proved to be inadequate to limit risks to financial stability, monetary policy should be considered as a possible defense.     

Credit and Banking in a DSGE Model of the Euro Area

This paper studies the role of credit supply factors in business cycle fluctuations using a dynamic stochastic general equilibrium (DSGE) model with financial frictions enriched with an imperfectly competitive banking sector. Banks issue collateralized loans to both households and firms, obtain funding via deposits, and accumulate capital out of retained earnings. Loan margins depend on the banks' capital‐to‐assets ratio and on the degree of interest rate stickiness. Balance‐sheet constraints establish a link between the business cycle, which affects bank profits and thus capital, and the supply and cost of loans. The model is estimated with Bayesian techniques using data for the euro area. The analysis delivers the following results. First, the banking sector and, in particular, sticky rates attenuate the effects of monetary policy shocks, while financial intermediation increases the propagation of supply shocks. Second, shocks originating in the banking sector explain the largest share of the contraction of economic activity in 2008, while macroeconomic shocks played a limited role. Third, an unexpected destruction of bank capital may have substantial effects on the economy.     

货币政策在银行危机管理中的效果

本文从货币政策的信贷传导渠道出发,探讨了金融危机条件下商业银行资本管理、准备金需求的变化、信贷配给对货币政策有效性的影响机制。分析表明,货币政策的有效性不仅取决于中央银行的政策意图,还受制于商业银行资本量、风险偏好以及信贷配给程度的变化。因此,强化危机时期的货币政策效果必须配合影响银行信贷行为的措施。     

Cost Channel of Monetary Policy: Financial Frictions and External Shocks

This paper deepens our understanding of the importance of the cost channel of monetary policy, where inflation adjusts with a firm's marginal cost of working capital. A model extended for a small, open economy with financial frictions is proposed and examined with data from Taiwan. The cost channel effect on inflation adjustment is substantiated by simultaneous generalized method of moments estimations and appears to be strengthened by financial frictions but mitigated by external shocks. Greater caution is hence required in the conduct of monetary policy for a bank-dependent emerging economy such as Taiwan because of the relative complexity in its supply-side interest rate pass-through.     

Jointly Optimal Regulation of Bank Capital and Liquidity

In an economy with financial frictions, banks endogenously choose excessive leverage and maturity mismatch in equilibrium, as they fail to internalize the risk of socially wasteful fire sales. Macroprudential regulators can achieve efficiency with simple linear constraints, which require less information than Pigouvian taxes. The liquidity coverage and net stable funding ratios of Basel III can implement efficiency. Additional microprudential regulation of leverage is required when bank failures are socially costly. Micro‐ and macroprudential rules are imperfect substitutes. Optimally, macroprudential policy reacts to systematic risk and credit conditions over the cycle, while microprudential policy reacts to systematic and idiosyncratic risk.     

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 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 credit growth and house price appreciation is then assessed using a dynamic panel data model. The main findings of the paper are: (1) Macroprudential policies have been used far more actively after the global financial crisis in both advanced and emerging economies. (2) These policies have primarily targeted the housing sector, especially in the advanced economies. (3) Macroprudential policies are usually changed in tandem with bank reserve requirements, capital flow restrictions, and monetary policy. (4) Our analysis suggests that macroprudential tightening is associated with lower bank credit growth, housing credit growth, and house price appreciation. (5) Targeted policies – for example, those specifically intended to limit house price appreciation – seem to be more effective, especially in economies where bank finance is important.     

Internal Capital Markets in Financial Conglomerates: Evidence from Small Bank Responses to Monetary Policy

This paper looks at internal capital markets in financial conglomerates by comparing the responses of small subsidiary and independent banks to monetary policy. I find that internal capital markets in financial conglomerates relax the credit constraints faced by smaller bank affiliates. Further analysis indicates that those markets lessen the impact of Fed policies on bank lending activity. The paper also examines the role of internal capital markets in influencing the investment allocation process of those conglomerates. My findings suggest that frictions between conglomerate headquarters and external capital markets are at the root of investment inefficiencies generated by internal capital markets.     

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.     

Towards a measure of financial fragility

The paper proposes a measure of financial fragility that is based on economic welfare in a general equilibrium model calibrated against UK data. The model comprises a household sector, three active heterogeneous banks, a central bank/regulator, incomplete markets, and endogenous default. We address the impact of monetary and regulatory policy, credit and capital shocks in the real and financial sectors and how the response of the economy to shocks relates to our measure of financial fragility. Finally we use panel VAR techniques to investigate the relationships between the factors that characterise financial fragility in our model, i.e. banks’ probabilities of default and banks’ profits – to a proxy of welfare.      

Optimal Monetary Policy and Transparency under Informational Frictions

This paper examines the optimal monetary policy and central bank transparency in an economy where firms set prices under informational frictions. The economy is subject to two types of shocks determining the efficient output level and firms' desired markups. To minimize the welfare‐reducing output gap and price dispersion between firms, the central bank controls firms' incentives and expectations by using a monetary instrument and disclosing information on the realized shocks. This paper shows that an optimal policy comprises the disclosure of a linear combination of the two shocks and the adjustment of monetary instruments contingent on the disclosed information.

The Trade Credit Channel of Monetary Policy Transmission: Evidence from Nonfinancial Manufacturing Firms in Turkey

This study investigates the trade credit channel of monetary policy transmission in Turkey by using a large panel of corporate firms and includes detailed information on balance sheets and income statements of firms that regularly reported to the Central Bank of the Republic of Turkey during the period 1996-2008. The study suggests that the composition of external finance differs considerably across firm types based on size and export performance under tight and loose financial conditions. Small and medium-size manufacturing firms and firms with a low export share are less likely to have access to bank finance, especially in tight periods. In addition, financially constrained firms with limited access to bank finance (small, low-export-share firms) tend to substitute trade credits for bank loans more aggressively in tight periods as monetary policy tightens. The large volume of trade credit on firms' balance sheets and its positive response to contractionary monetary shocks imply that the trade credit channel might subdue the traditional credit channel of monetary transmission.     

Capital controls and monetary policy autonomy in a small open economy

Is there a link between capital controls and monetary policy autonomy in a country with a floating currency? Shocks to capital flows into a small open economy lead to volatility in asset prices and credit supply. To lessen the impact of capital flows on financial instability, a central bank finds it optimal to use the domestic interest rate to “manage” the capital account. Capital account restrictions affect the behavior of optimal monetary policy following shocks to the foreign interest rate. Capital controls allow optimal monetary policy to focus less on the foreign interest rate and more on domestic variables.
