We examine how climate risk influences analyst forecast accuracy proxied by forecast error and dispersion. Using country-level climate risk estimated with time trends in droughts, we find that analyst forecasts are less accurate for firms in drought-prone countries. This effect of climate risk is stronger when climate risks are denoted in earnings forecasts, and when firms’ home countries have greater reliance on hydroelectric sources in electricity generation, more important agricultural and food industries, and active stances concerning climate change. Overall, our findings suggest noteworthy implications of climate risk on the financial markets via analyst forecast accuracy.
我们研究了气候风险如何影响以预测误差和离散度为代表的分析师预测准确性。通过利用干旱的时间趋势估算国家级气候风险,我们发现分析师对干旱多发国家的公司预测准确性较低。如果在盈利预测中指出气候风险,而且公司的母国更依赖水力发电、农业和食品工业更重要、对气候变化持积极态度,那么气候风险的影响就更大。总之,我们的研究结果表明,气候风险会通过分析师预测的准确性对金融市场产生值得注意的影响。

Using a panel of 496 banks from the G20 nations, the study assesses the role of macroprudential policies in reducing systemic risk. The study further assesses the utility of these policies in conjunction with monetary policy instruments and bank and country-specific characteristics and finds the significant impact of macroprudential policies in curbing systemic risk and promoting economic stability. The study finds this relationship to hold regardless of economic conditions like inflationary pressure and financial distress. The result highlights that easing macroprudential policies during financial distress can help banks cope with systemic losses. We split the macroprudential policies into policies targeting the demand and supply of loans and find complementarity among the policies to reduce systemic risk. Our results demonstrate the heterogenous effect of macroprudential policies in limiting systemic risk, with the effect varying with bank size, leverage, liquidity, and concentration of loans. Finally, we find a moderating role of these policies in limiting the impact of uncertainties on systemic risk.
该研究利用来自 20 国集团国家的 496 家银行组成的面板,评估了宏观审慎政策在降低系统性风险方面的作用。研究进一步评估了这些政策与货币政策工具以及银行和国家具体特征相结合的效用,发现宏观审慎政策在抑制系统性风险和促进经济稳定方面具有重大影响。研究发现,无论通胀压力和金融困境等经济条件如何,这种关系都是成立的。这一结果突出表明,在金融困境期间放松宏观审慎政策可以帮助银行应对系统性损失。我们将宏观审慎政策分为针对贷款需求和供给的政策,并发现这些政策在降低系统性风险方面具有互补性。我们的研究结果表明,宏观审慎政策在限制系统性风险方面具有不同的效果,其效果因银行规模、杠杆率、流动性和贷款集中度而异。最后,我们发现这些政策在限制不确定性对系统性风险的影响方面起着调节作用。

Estimating the impact of supply chain network contagion on financial stability 估算供应链网络传染对金融稳定的影响

Realistic credit risk assessment, the estimation of losses due to a debtors failure, is central for maintaining financial stability. Credit risk models focus on the financial conditions of borrowers and only marginally consider other risks from the real economy, supply chains in particular. Recent pandemics, geopolitical instabilities, and natural disasters demonstrated that supply chain shocks can contribute to financial losses large enough to threaten financial stability. Based on a unique nation-wide micro-dataset, containing practically all supply chain relations of all Hungarian firms, together with their bank loans, we develop a multi-layer shock propagation framework to estimate how economic shocks to firms cascade in the supply chain network (SCN), leading to additional financial losses to firms, additional defaults of loans and, hence, losses to banks’ equity buffers. First, we estimate the financial systemic risk of individual firms, by quantifying the expected financial losses caused by a firm’s own- and all the secondary defaulting loans caused by supply chain network contagion. We find a small fraction of firms carrying substantial financial systemic risk, affecting up to 22% of the banking system’s overall equity (assuming a loss given default of 100%). These losses are predominantly caused by SCN-contagion. Second, we calculate for every bank the expected loss (EL), value at risk (VaR) and expected shortfall (ES), with and without SCN-contagion. We find that SCN-contagion amplifies EL, VaR, and ES by a factor of 5.2, 6.7 and 4.4, respectively. Third, we showcase how the new framework can be used to assess the risks of a large real economy shock for financial stability. We simulate the financial losses from a COVID-19 inspired shock calibrated from firm-level employment data in the beginning of 2020. Our simulations show that without any interventions, system-wide bank equity would suffer losses of 6%. The framework can be used to design and test targeted policy interventions, e.g., optimally providing firms with enough liquidity-support to avert their default. By supporting selected illiquid (yet solvent) firms with additional liquidity totalling 0.5% of overall bank equity, the losses can be reduced from 6% to 1% of overall bank equity. These findings indicate that for a more complete picture of financial stability and realistic credit risk assessment, SCN contagion needs to be considered. This now quantifiable contagion channel is of relevance for future systemic risk assessments of regulators.
现实的信用风险评估,即估算债务人倒闭造成的损失,是维护金融稳定的核心。信用风险模型侧重于借款人的财务状况,对实体经济,特别是供应链的其他风险考虑甚少。最近的大流行病、地缘政治动荡和自然灾害表明,供应链冲击可造成足以威胁金融稳定的巨大金融损失。基于一个独特的全国性微观数据集(其中包含匈牙利所有企业的几乎所有供应链关系及其银行贷款),我们开发了一个多层次冲击传播框架,以估算企业受到的经济冲击如何在供应链网络(SCN)中产生连锁反应,从而导致企业遭受额外的财务损失、更多的贷款违约,进而给银行的股本缓冲带来损失。首先,我们估算了单个企业的金融系统性风险,量化了由供应链网络传染引起的企业自身和所有次级违约贷款造成的预期金融损失。我们发现,有一小部分企业会带来巨大的金融系统性风险,影响银行系统整体权益的 22%(假设违约损失为 100%)。这些损失主要是由 SCN 感染造成的。其次,我们计算了每家银行的预期损失(EL)、风险价值(VaR)和预期亏空(ES),包括 SCN 感染和无 SCN 感染的情况。我们发现,SCN-contagion 将 EL、VaR 和 ES 分别放大了 5.2、6.7 和 4.4 倍。第三,我们展示了如何利用新框架来评估实体经济大幅冲击对金融稳定的风险。我们模拟了 2020 年初由企业级就业数据校准的 COVID-19 激发的冲击所造成的金融损失。我们的模拟结果表明,如果不采取任何干预措施,整个系统的银行股本将遭受 6% 的损失。该框架可用于设计和测试有针对性的政策干预措施,例如,以最佳方式为企业提供足够的流动性支持,以避免其违约。通过向选定的流动性不足(但有偿付能力)的企业提供总额为银行总股本 0.5%的额外流动性支持,可将损失从银行总股本的 6%降至 1%。这些研究结果表明,为了更全面地反映金融稳定性和进行现实的信贷风险评估,需要考虑 SCN 传染。这一现在可以量化的传染渠道对监管机构未来的系统性风险评估具有重要意义。

SRISK is a measure of a firms' systemic risk contribution that is computed using its listed stock market price. SRISK measurement is extended and applied to firms that do not have listed equity. A mapping from balance sheet characteristics to SRISK for listed firms is applied to SRISK for unlisted European banks. The mapping is validated by comparing SRISK measures for unlisted banks with their losses in European bank stress-testing.

In this study, we examine the trading book of a major dealer in the European unsecured money market, focusing on the impact of a dealer’s own funding liquidity risk on the pricing of his interbank trades pre- and post- the 2007/08 financial crisis. Our analysis reveals two key insights: First, utilizing a panel model, we observe that heightened funding liquidity risks for the dealer generally affect his quoted prices for interbank liquidity. Second, while in tranquil periods this effect is statistically significant but economically less pronounced, the collapse of Lehman Brothers led to a strong liquidity pricing effect: a one standard deviation increase in the funding liquidity risk of the dealer translated to a 11 basis points higher mid-price for overnight liquidity. We thus find evidence that funding liquidity risks exacerbated the overall contraction of money market liquidity during this period.
在本研究中,我们考察了欧洲无担保货币市场上一家主要交易商的交易账簿,重点研究了 2007/08 年金融危机前后交易商自身的资金流动性风险对其银行间交易定价的影响。我们的分析揭示了两个关键问题:首先,利用面板模型,我们发现交易商资金流动性风险的增加通常会影响其银行间流动性的报价。其次,在平静时期,这种影响在统计上是显著的,但在经济上并不那么明显,而雷曼兄弟的倒闭则导致了强烈的流动性定价效应:交易商的资金流动性风险每增加一个标准差,隔夜流动性的中间价格就会提高 11 个基点。因此,我们发现有证据表明,资金流动性风险加剧了这一时期货币市场流动性的整体收缩。

This paper investigates the pricing of insolvent banks in the U.S. that are sold under the purchase and assumption resolution method of the Federal Deposit Insurance Corporation (FDIC). We consider quarterly data for 444 acquisitions of insolvent U.S. banks between 2009 and 2016. We find that acquirers not only pay higher prices for insolvent banks with larger core deposits, as has been highlighted by the literature (and is consistent with the FDIC’s beliefs), but also for those banks with larger branch networks that are less dispersed geographically. When the acquirers bid (separately) for the assets of the insolvent banks, they place a positive value on the number of branches of the insolvent bank, but appear to be insensitive to geographic dispersion. Acquirers also pay more for banks with a national charter. The results additionally show that failed banks are most likely to be acquired by relatively large and highly capitalized banks whose organic growth is not affected in the years following the acquisition. Overall, our findings contribute to a better understanding of the implications of the purchase and assumption resolution method for the FDIC and for the banking industry.
本文研究了根据美国联邦存款保险公司(FDIC)的购买和承担解决方法出售的美国破产银行的定价问题。我们考虑了 2009 年至 2016 年间 444 起美国破产银行收购案的季度数据。我们发现,收购方不仅为核心存款规模较大的破产银行支付了更高的价格,这一点已为文献所强调(也与联邦存款保险公司的观点一致),而且还为那些分支网络规模较大、地理位置不太分散的银行支付了更高的价格。当收购者(单独)竞购破产银行的资产时,他们对破产银行的分支机构数量给予了积极的评价,但似乎对地域分散性并不敏感。收购者也会为拥有国家特许经营权的银行支付更高的价格。研究结果还表明,破产银行最有可能被规模相对较大、资本雄厚的银行收购,这些银行在被收购后几年内的内生增长不会受到影响。总之,我们的研究结果有助于更好地理解购买和承担的解决方法对联邦存款保险公司和银行业的影响。

Do repeated government infusions help financial stability? Evidence from an emerging market 政府反复注资是否有助于金融稳定?新兴市场的证据

While government led bank capital infusions in US and other developed markets have been usually contingent an external shock or crisis episode, India presents a unique setting where significant capital infusions happen annually to stabilize the weak balance sheets of undercapitalized government owned public sector banks. Such “repeated” capital infusions can either better engender financial stability, given the timely government interventions; or create instability arising from possible moral hazard concerns. "Do such repeated government capital infusions lower banks’ financial risks and improve financial stability?” We shed light on the question through the lens of capital infusions in the Indian market. Based on the exhaustive sample of government capital infusions into public sector banks for the period 2008–18, we find robust evidence that capital infusions are associated with economically significant higher default, capital shortfall and network risks post-infusion, signaling a moral hazard problem, where treated banks may assume more risky investments.
在美国和其他发达市场,政府主导的银行注资通常是在外部冲击或危机事件发生时进行的,而印度则是一个独特的环境,每年都会注入大量资本,以稳定政府拥有的公共部门银行薄弱的资产负债表。由于政府干预及时,这种 "重复 "的资本注入既可以更好地促进金融稳定,也可以因可能存在的道德风险问题而造成不稳定。"这种重复的政府资本注入是否会降低银行的金融风险并提高金融稳定性?我们通过印度市场的资本注入情况来揭示这个问题。基于 2008-18 年期间政府向公共部门银行注资的详尽样本,我们发现了有力的证据,表明注资与注资后违约、资本缺口和网络风险的经济显著上升相关,这表明存在道德风险问题,即接受注资的银行可能会承担更高的投资风险。

Capital controls in China: A necessity for macroeconomic stability 中国的资本管制:宏观经济稳定的必要性

This paper investigates the crucial role of capital controls in maintaining macroeconomic stability in China. We develop an open macroeconomic model integrating capital controls within a managed floating exchange rate system. Our model shows that capital controls enhance the effectiveness of foreign exchange interventions by restricting capital outflows and providing a broader array of policy options, though they may also create discrepancies between domestic and foreign asset holdings. Simulations using quarterly time-series data reveal that capital controls are essential for the success of both sterilized and non-sterilized interventions. These results indicate that the combined use of capital controls and foreign exchange interventions can reduce macroeconomic volatility in China. Moreover, our analysis of fixed versus floating exchange rate regimes suggests that an inappropriate regime choice can increase volatility in capital flows.

本文探讨了资本管制在维护中国宏观经济稳定方面的关键作用。我们建立了一个开放的宏观经济模型,将资本管制纳入有管理的浮动汇率体系。我们的模型表明,资本管制通过限制资本外流和提供更广泛的政策选择,提高了外汇干预的有效性,尽管资本管制也可能造成国内外资产持有量的差异。利用季度时间序列数据进行的模拟显示,资本管制对消毒干预和非消毒干预的成功都至关重要。这些结果表明,结合使用资本管制和外汇干预措施可以降低中国宏观经济的波动性。此外,我们对固定汇率和浮动汇率制度的分析表明,制度选择不当会增加资本流动的波动性。因此,中国应在有管理的浮动汇率制度内采用平衡的金融方法来稳定宏观经济。

This study examines the role of independent directors’ network centrality in bank risk-taking. Following the shareholder-incentive hypothesis and social-network theory, we predict and find that independent directors’ connectedness is positively associated with bank risk-taking. The results hold after a battery of robustness checks and endogeneity tests. Furthermore, consistent with the influence channel of networks, we show that connectedness empowers independent directors, whereas influential independent directors facilitate aggressive investment. We also find that the risk-taking effects are more pronounced for complex banks and banks with higher equity capital, higher income diversity, and lower cost-efficiency.

本研究探讨了独立董事的网络中心性在银行风险承担中的作用。根据股东激励假说和社会网络理论,我们预测并发现独立董事的人脉关系与银行风险承担正相关。经过一系列稳健性检验和内生性检验后,结果成立。此外,与网络的影响渠道一致,我们表明,关联性增强了独立董事的能力,而有影响力的独立董事促进了激进投资。我们还发现,风险承担效应对于复杂银行和股权资本较高、收入多元化程度较高以及成本效率较低的银行更为明显。

Bank runs and media freedom: What you don’t know won’t hurt you? 银行挤兑与媒体自由:你不知道的事不会伤害你?

This paper examines the influence of media freedom restrictions on retail depositor behavior during banking crises. Non-professional, retail depositors are particularly affected due to insufficient access to vital information about the banking industry's vulnerability and broad macroeconomic conditions amidst the crisis. Using data from 85 countries from 2004 to 2019, we found that during crises, higher media restrictions lead to an increase in the rate of household deposit withdrawals. If media restrictions hinder depositors from accurately assessing the banking sector’s exposure, there is a higher likelihood of panic-based response in uncertain times brought on by the banking crisis, potentially triggering bank runs. Furthermore, our results reveal that lower banking sector risk can mitigate the negative effect of media restrictions on retail deposit growth during a banking crisis, especially in middle-income OECD and non-OECD countries, countries with stronger institutional environments, and countries with higher financial literacy. As a policy suggestion, promoting financial literacy could help reduce information asymmetry and prevent panic withdrawals, even in environments with significant media restrictions.

本文探讨了银行危机期间媒体自由限制对零售储户行为的影响。非专业的零售储户由于无法充分获取有关危机中银行业脆弱性和宏观经济状况的重要信息,因此受到的影响尤为严重。利用 2004 年至 2019 年 85 个国家的数据,我们发现在危机期间,较高的媒体限制会导致家庭存款提取率上升。如果媒体限制阻碍了储户准确评估银行业的风险敞口,那么在银行业危机带来的不确定时期,储户就更有可能做出恐慌性反应,从而可能引发银行挤兑。此外,我们的研究结果表明,在银行业危机期间,较低的银行业风险可以减轻媒体限制对零售存款增长的负面影响,尤其是在中等收入的经合组织和非经合组织国家、制度环境较强的国家以及金融知识较高的国家。作为一项政策建议,促进金融知识普及有助于减少信息不对称,防止恐慌性撤资,即使是在有重大媒体限制的环境中也是如此。
