Does bank capital affect lending behavior?

This paper investigates the existence of cross-sectional differences in the response of lending to monetary policy and GDP shocks owing to differences in bank capitalization. It adds to the literature by using the excess capital-to-asset ratio, which can better control the riskiness of banks' portfolios, and by disentangling the effects of the “bank lending channel” from those of the “bank capital channel.” The results, based on a sample of Italian banks, indicate that bank capital matters in the propagation of different types of shocks to lending, owing to the existence of regulatory capital constraints and imperfections in the market for bank fund-raising.     

Does competition influence the bank lending channel in the euro area?

This paper examines how competition influences the bank lending channel in the euro area countries. Using a large panel of banks from 12 euro area countries for the period 2002–2010 we analyze the reaction of loan supply to monetary policy actions depending on the degree of bank competition. We find that the effect of monetary policy on bank lending is dependent on bank competition: the transmission of monetary policy via the bank lending channel is less pronounced for banks with extensive market power. Further investigation shows that banks with less market power were more sensitive to monetary policy only before the financial crisis. These results suggest that bank market power has a significant impact on the effectiveness of monetary policy. Therefore, wide variations in the level of bank market power may lead to asymmetric effects of the single monetary policy.

The welfare costs of expected and unexpected inflation

The monetary search model by Lagos and Wright (2005) is extended with imperfect information about nominal shocks as in Lucas (1972). An analytical solution exists with logarithmic preferences. In general, individuals hold precautionary balances. Calibrated to United States postwar data, the welfare cost of the monetary cycle is calculated to be small (below 0.0003% of GDP) compared to the welfare cost of the inflation tax (around 0.25% of GDP). The main reason for the minute welfare cost of the monetary cycle is its low amplitude in 1947-2007. But, monetary crashes, such as those experienced during the Great Depression, can generate important welfare costs.     

宏观审慎政策的角色

本文基于宏观审慎目标、理论动因和风险传播渠道,探讨了是否应该追加全局性资本金以平抑经济周期。全局性资本金追加要求可以一刀切或者区别对待,区别对待的方法有利于更好地掌控风险,但必须慎重考量区别对待的适度水平,可通过一系列定量和定性指标来调校全局性资本金追加标准;宏观审慎决策需要一定的相机抉择,但必须对其施加相应的约束以保障政策的透明度、责任性和前瞻性,建议制定完备的责任约束机制,从而形成"有约束的相机抉择"的宏观审慎机制;一国宏观审慎制度需要得到国际合作与配合才能充分地发挥效力。     

Liquidity, redistribution, and the welfare cost of inflation

The long-run welfare costs of inflation are studied in a micro-founded model with trading frictions and costly liquidity management. By modelling the liquidity management decision, the model endogenizes the responses of velocity, output, the degree of market segmentation, and the distribution of money. Compared to the traditional estimates based on a representative agent model, the welfare costs of inflation are significantly smaller due to distributional effects of inflation. The welfare cost of increasing inflation from 0% to 10% is 0.62% of consumption for the US economy. Furthermore, the welfare cost is generally non-linear in the inflation rate.     

Financial institutions’ business models and the global transmission of monetary policy

Global financial institutions play an important role in channeling funds across countries and, therefore, transmitting monetary policy from one country to another. In this paper, we study whether such international transmission depends on financial institutions’ business models. In particular, we use Dutch, Spanish, and U.S. confidential supervisory data to test whether the transmission operates differently through banks, insurance companies, and pension funds. We find marked heterogeneity in the transmission of monetary policy across the three types of institutions, across the three banking systems, and across banks within each banking system. While insurance companies and pension funds do not transmit home-country monetary policy internationally, banks do, with the direction and strength of the transmission determined by their business models and balance sheet characteristics.     

The welfare cost of bank capital requirements

Capital requirements are the cornerstone of modern bank regulation, yet little is known about their welfare cost. This paper measures this cost and finds that it is surprisingly large. I present a simple framework, which embeds the role of liquidity creating banks in an otherwise standard general equilibrium growth model. A capital requirement limits the moral hazard on the part of banks that arises due to deposit insurance. However, this capital requirement is also costly because it reduces the ability of banks to create liquidity. The key insight is that equilibrium asset returns reveal the strength of households’ preferences for liquidity and this allows for the derivation of a simple formula for the welfare cost of capital requirements that is a function of observable variables only. Using US data, the welfare cost of current capital adequacy regulation is found to be equivalent to a permanent loss in consumption of between 0.1% and 1%.

从固定资产重估看银行资本的提升

分析在国内外会计准则下,通过固定资产重估提升银行资本、缓解监管压力的可行性。根据我国会计准则的相关要求,在固定资产重估方面,目前只能通过投资性房地产重估、固定资产转换与并购重组三种路径提升银行资本,从而达到提升资本充足率的目的,但前两种方法却在一定程度上降低了杠杆率水平,且其市场实施效果也并不乐观。     

On the role of Islamic and conventional banks in the monetary policy transmission in Malaysia: Do size and liquidity matter?

This paper empirically investigates the impact of monetary policy on the credit supply of Islamic versus conventional banks of Malaysia using an unbalanced panel dataset over the period 2005-2016. While estimating the effects of three alternative measures of monetary policy on banks' credit supply, we include several bank-specific and macroeconomic variables in the specification as control variables. We provide strong evidence on the existence of the credit channel of monetary policy transmission mechanism in Malaysia. Yet, we show that Islamic banks respond considerably less to changes in monetary policy instruments as compared to their conventional counterparts. We also find that the monetary policy measures affect small-sized banks and less-liquid banks more as compared to large-sized and more-liquid banks. Our findings suggest that for an effective monetary policy, there is a vital need to consider the nature of Islamic banking while devising any monetary policy instruments to manage credit supply in the economy.     

Do negative interest rates affect bank risk-taking?

We offer early evidence on the impact of negative interest rate policy (NIRP) on banks’ risk-taking. Our primary result shows banks in NIRP-adopter countries reduce holdings of risky assets by around 10 percentage points following implementation of NIRP in comparison to banks in non-adopter countries. We augment this result by identifying NIRP’s impact on other aspects of banks’ risk-taking behaviour; NIRP is associated with reductions in banks’ loan growth and average loan price (by 3.7 percentage points and 59 basis points) and a rebalancing of asset portfolios towards safer assets. Secondly, we find the NIRP-effect is heterogeneous; post-NIRP risk-taking increases at strongly capitalised banks and at banks operating in less competitive markets that exploit market power to insulate net interest margins and profitability. Our robust empirical evidence supports the “de-leverage” hypothesis which suggests that banks acquire safer, liquid assets to bolster their capital positions rather than searching for value by acquiring riskier assets. We base our evidence on a sample of 2,584 banks from 33 OECD countries across 2012 to 2016, and from models that employ a difference-in-differences framework.
