Anna‐Leigh Stone
This paper is the first to examine the unlimited deposit insurance on noninterest-bearing transaction accounts (NIBTAs) provided by Section 343 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank). During Dodd-Frank, banks had a smaller ratio of NIBTAs compared to later periods without the unlimited insurance but have larger deposit flows in NIBTAs over the $250,000 FDIC limit. The results suggest that depositors took advantage of the unlimited insurance, but that banks were not harmed by drawdowns when the insurance expired. Furthermore, the results suggest that emergency deposit insurance might be a good complement to FDIC insurance during recessionary times.
本文首次考察了《多德-弗兰克华尔街改革与消费者保护法》(Dodd-Frank Wall Street Reform and Consumer Protection Act)第343条对无息交易账户(NIBTAs)提供的无限制存款保险。在多德-弗兰克法案实施期间,与没有无限保险的后期相比,银行的nibta比例较小,但nibta的存款流量超过了25万美元的FDIC上限。结果表明,存款人利用了无限保险,但当保险到期时,银行并没有受到提款的损害。此外,结果表明,紧急存款保险可能是一个很好的补充FDIC保险在经济衰退时期。

Indirect Maturity Transformations 间接成熟度转换
Pub Date : 2021-06-18 DOI: 10.2139/ssrn.3906275

This paper compares `direct maturity transformations' (DMTs), in which risky long-term assets are directly financed with short-term debt, with `indirect maturity transformations' (IMTs), in which such assets are financed with long-term debt that is financed with short-term debt in a second, separate step. Analyzing the properties of debt contracts I show that the default probability of short-term debt is higher in case of an IMT than in case of a direct transformation - for the same assets and the same level of short-term debt. Based on a model of financial intermediation I suggest two reasons why IMTs can be privately optimal although they entail a higher solvency risk than DMTs: first, the indirect reference of short-term debt to the underlying assets can decrease liquidity risk; second, IMTs allow for regulatory arbitrage in case of capital requirements that do not take account of the different solvency risk of IMTs and DMTs.
本文比较了“直接期限转换”(dmt)和“间接期限转换”(IMTs),前者风险长期资产直接由短期债务融资,后者此类资产由长期债务融资,并在第二个单独步骤中由短期债务融资。通过分析债务契约的性质,我发现,对于相同的资产和相同水平的短期债务,IMT情况下短期债务的违约概率高于直接转换情况。基于金融中介模型,我提出了两个原因,为什么imt可以是私人最优的,尽管它们比dmt需要更高的偿付能力风险:首先,短期债务对基础资产的间接参考可以降低流动性风险;其次,在没有考虑到imt和dmt不同偿付能力风险的资本要求的情况下,imt允许监管套利。

We study the 'interconnectedness' of stress-tested banks by exploiting how they are mentioned together in the context of financial news. We start by constructing weekly co-occurrence network matrices following Ronnqvist and Sarlin (2015) text-to-network approach. Using the COVID-19 pandemic as an external shock, we examine how bank networks behave during high stress periods. We find that banks become more interconnected during peaks of COVID-19 induced stress. We put forth a new measure of systemic risk that utilizes text-based eigenvector centrality. This measure provides a more stable ranking system than the traditional SRISK measure during both high and low stress periods.
我们研究了压力测试银行的“互联性”,利用他们如何在金融新闻的背景下一起被提及。我们首先根据Ronnqvist和Sarlin(2015)文本到网络的方法构建每周共现网络矩阵。以2019冠状病毒病大流行为外部冲击,我们研究了银行网络在高压力时期的表现。我们发现,在COVID-19引发的压力高峰期间,银行之间的联系变得更加紧密。我们提出了一种利用基于文本的特征向量中心性的系统风险度量方法。无论在高压力期还是低压力期,该方法都比传统的SRISK方法提供了一个更稳定的排名系统。

Is It Time for Nigeria To Regulate Cryptocurrency? 尼日利亚是时候监管加密货币了吗?
Pub Date : 2021-02-19 DOI: 10.2139/ssrn.3788831

The digital and tech industry of Nigeria woke up to what could be better termed 'nightmare at dawn' in the early hours of Friday 5 February 2021 following the letter from the Central Bank of Nigeria (CBN) to all deposit money banks, non-bank financial institutions and other financial institutions in which the CBN referred them to the CBN circular of 12 January 2017 wherein the CBN cautioned all deposit money banks (DMB), non-bank financial institutions (NBFIs), other financial institutions (OFIs) and members of the public on the risk associated with transactions in crypto currency.

In the letter, the CBN further to the directive on the circular, called the attention of regulated institutions that dealing in crypto currencies and facilitating payments for cryptocurrency exchanges is prohibited in Nigeria. Flowing from the above, CBN directed regulated institutions listed above to identify persons and or entities transacting in or operating crypto currency exchange within their systems and ensure that such accounts are closed immediately. News of the CBN's decision to prohibit banks from facilitating crypto-related transactions through the banking system has since gotten very harsh reactions on social media, the tech and digital market with many condemning the policy as a deliberate attempt by the government to impoverish young Nigerians who have been able to create wealth for themselves through crypto trading.

Following the outburst on social media, the CBN did a press release on 7 February 2021 therein they stated that they are not an outlier in its decision and further listed countries and prominent investors who share the same opinion on crypto currency. In the press release, the CBN announced that the major reasons backing up their decision on banning transaction on cryptocurrencies are potential risk of loss of investments, money laundering, terrorism financing, illicit fund flows and criminal activities. These reasons are only reasonable as the crypto currency market is not regulated and can be manipulated in many ways.

Some have also noted the lack of policy cooperation between financial regulators in Nigeria due to the fact that the SEC had only a few months ago proposed a new set of rules that will regulate crypto-token or Crypto-coin investments when the character of the investment qualifies as securities transactions. Flowing from this, SEC did a press release clarifying that they are not in any contradiction with CBN and are currently engaged with the CBN and agreed to work together to further analyze, and better understand the identified risks to ensure that appropriate and adequate mitigants are put in place, should such securities be allowed in the future. SEC has also by the press release stated that they have put on hold assessment of all persons (and products) seeking admittance into the SEC Regulatory Incubation Framework who are affected by the CBN letter of 05 February 2021. The entire situation has got
在尼日利亚中央银行(CBN)向所有存款银行,非银行金融机构和其他金融机构致函之后,尼日利亚的数字和技术行业在2021年2月5日星期五凌晨醒来,可以更好地称为“黎明时分的噩梦”,其中CBN将其提交给2017年1月12日的CBN通知,其中CBN警告所有存款银行(DMB),非银行金融机构(nbfi),其他金融机构(ofi)和公众对加密货币交易相关风险的认识。在这封信中,CBN进一步对该通知的指令进行了补充,呼吁受监管机构注意,尼日利亚禁止交易加密货币和促进加密货币交易所的支付。综上所述,CBN指示上述受监管机构识别在其系统内进行加密货币交易或操作加密货币交易的个人和实体,并确保立即关闭此类账户。CBN决定禁止银行通过银行系统为加密相关交易提供便利的消息在社交媒体、科技和数字市场上引起了非常严厉的反应,许多人谴责该政策是政府故意让那些能够通过加密交易为自己创造财富的尼日利亚年轻人陷入贫困。在社交媒体上爆发后,CBN于2021年2月7日发布了一份新闻稿,其中表示他们并不是其决定的例外,并进一步列出了对加密货币持相同意见的国家和知名投资者。在新闻稿中,CBN宣布,支持他们决定禁止加密货币交易的主要原因是投资损失、洗钱、恐怖主义融资、非法资金流动和犯罪活动的潜在风险。这些理由是合理的,因为加密货币市场不受监管,可以通过多种方式被操纵。一些人还指出,尼日利亚金融监管机构之间缺乏政策合作,因为美国证券交易委员会(SEC)几个月前才提出了一套新的规则,当投资的性质符合证券交易条件时,这些规则将对加密代币或加密货币投资进行监管。由此,美国证券交易委员会发布了一份新闻稿,澄清他们与CBN没有任何矛盾,目前正在与CBN合作,并同意共同努力,进一步分析并更好地了解已确定的风险,以确保在未来允许此类证券的情况下,采取适当和充分的缓解措施。SEC还在新闻稿中表示,他们已暂停评估所有寻求进入SEC监管孵化框架的人(和产品),这些人(和产品)受到2021年2月5日CBN信函的影响。整个情况引起了尼日利亚参议院的注意,参议院已授权其银行,保险和其他金融机构,信息通信技术和网络犯罪以及资本市场委员会邀请CBN行长以及SEC总干事向其介绍该国最近禁止加密货币的情况。它解释说,从两个监管机构的简报中产生的信息将帮助参议院确定加密货币对国家经济和安全的机会和威胁。加密货币交易所币安在推特上敦促其尼日利亚客户“尽早撤回您的NGN,以避免潜在的渠道问题”,同时还指出,新的CBN法律是尼日利亚采用加密货币的“一步”。剑桥词典将加密货币定义为由公共网络产生的数字货币,而不是任何政府,它使用加密技术来确保支付的发送和接收安全。QUARTZ AFRICA将尼日利亚列为全球第二大加密市场。本文旨在讨论困扰尼日利亚人的问题,因为它与CBN通告和加密货币有关,例如加密货币的交易发生在哪里(无论是多司法管辖区还是司法管辖区),加密货币是否是财产,其他国家对加密货币的看法等。

(Un)intended Consequences of Macroprudential Regulation (非)宏观审慎监管的预期后果
Pub Date : 2021-02-18 DOI: 10.2139/ssrn.3788156

The chapter examines the effects of several macroprudential tools on household choices in the mortgage market. In recent years, following the global financial crisis, central banks have imposed macroprudential policy tools on mortgage loans in order to protect the banking system from systemic risk associated with highly leveraged homeowners. Using a unique and detailed dataset on mortgage loans taken in Israel in the last decade, we empirically estimate the impact of these regulations on household choices and the housing market. In particular, we examine borrowers’ response to the following regulatory restrictions: Loan-to-Value (LTV) limits of 75% for first time buyers, 70% for home improvers, and 50% for investors; a payment-to-income (PTI) limit of 50%; a 2/3 limit on the adjustable rate component; and a 30-year maturity limit. We found that overall, the regulatory provisions tested in this project influenced the borrowers’ responses. Interestingly, two of these provisions served as an anchor to the borrowers. We obtained an increase in mortgage loans maturity following the imposed maturity limit and an increase in PTI ratio following the imposed PTI limits. We argue that these unintended consequences of the tested macroprudential regulation are a result of the anchoring and adjustment heuristic.
本章考察了几种宏观审慎工具对抵押贷款市场中家庭选择的影响。近年来,在全球金融危机之后,各国央行对抵押贷款实施了宏观审慎政策工具,以保护银行体系免受与高杠杆房主相关的系统性风险。利用过去十年中以色列抵押贷款的独特而详细的数据集,我们经验地估计了这些法规对家庭选择和住房市场的影响。我们特别研究了借款人对以下监管限制的反应:首次购房者的贷款价值比(LTV)限制为75%,房屋改善者为70%,投资者为50%;供款与入息之比的上限为50%;可调速率组件上的2/3限制;期限为30年。我们发现,总体而言,在本项目中测试的监管条款影响了借款人的反应。有趣的是,这些条款中有两项对借款人起到了锚定作用。我们在规定的期限限制之后获得了抵押贷款期限的增加,在规定的PTI限制之后获得了PTI比率的增加。我们认为,经过测试的宏观审慎监管的这些意想不到的后果是锚定和调整启发式的结果。

Deconstructing Systemic Risk: A Reverse Stress Testing Approach 解构系统风险:反向压力测试方法
Pub Date : 2021-02-10 DOI: 10.2139/ssrn.3783224
Javier Ojea Ferreiro
The financial sector faces different systemic events. The early recognition of these events is a key step to monitor and track possible financial crises. Three main questions arise related to systemic risk, and they deal with their quantification, their probability of occurrence and the role of main contributors. This paper proposes a methodology based on a reverse stress test exercise to shed light on these questions. Time series and cross-section information regarding systemic risk are obtained. Further, an assessment of how these results of systemic assessment could change depending on key parameters in a Gaussian framework is undertaken and, finally, a small empirical exercise is performed.

The Impact of External Governance and Regulatory Settings on the Profitability of Islamic Banks: Evidence from Arab Markets 外部治理和监管设置对伊斯兰银行盈利能力的影响:来自阿拉伯市场的证据
Pub Date : 2021-02-08 DOI: 10.2139/ssrn.3782745
Seyed Alireza Athari, Mahboubeh Bahreini
This study specifically investigates the effects of external governance mechanisms and regulatory settings on the profitability of Islamic banks operating in the Arab markets from 2003 to 2017. The empirical results underscore that the external governance mechanism and its dimensions in particular the political stability, regulatory quality, rule of law, and control of corruption impact Islamic banks’ profitability positively. However, the regulatory settings and its sub-indices particularly the extent of disclosure and ease of shareholder suits have the opposite effect. Likewise, the results of traditional determinants indicate that the profitability of Islamic banks is shaped by the bank-specific, industry-specific, and country and global-level determinants. Results are robust and consistent with alternative estimation procedures and also support for the negative and positive effect of voice and accountability external governance’s dimension and inflation, respectively. The findings of this study have important policy implications for regulators, policymakers, and banks’ managers.
本研究专门调查了外部治理机制和监管设置对2003年至2017年在阿拉伯市场运营的伊斯兰银行盈利能力的影响。实证结果表明,外部治理机制及其维度,特别是政治稳定、监管质量、法治和腐败控制,对伊斯兰银行的盈利能力有积极影响。然而,监管环境及其分类指数,尤其是披露程度和股东诉讼难易程度,却产生了相反的效果。同样,传统决定因素的结果表明,伊斯兰银行的盈利能力是由银行特定的、行业特定的、国家和全球层面的决定因素决定的。结果是稳健的,与可选的估计程序一致,并且还分别支持声音和问责制外部治理维度和通货膨胀的消极和积极影响。本研究结果对监管机构、政策制定者和银行管理者具有重要的政策意义。

The More the Merrier? Evidence from the Global Financial Crisis on the Value of Multiple Requirements in Bank Regulation 人越多越好?全球金融危机对银行监管多重要求价值的实证研究

This paper assesses the value of multiple requirements in bank regulation using a novel empirical rule‑based methodology. Exploiting a dataset of capital and liquidity ratios for a sample of global banks in 2005 and 2006, we apply simple threshold-based rules to assess how different regulations individually and in combination might have identified banks that subsequently failed during the global financial crisis. Our results generally support the case for a small portfolio of different regulatory metrics. Under the objective of correctly identifying a high proportion of banks which subsequently failed, we find that a portfolio of a leverage ratio, a risk-weighted capital ratio, and a net stable funding ratio yields fewer false alarms than any of these metrics individually – and at less stringent calibrations of each individual regulatory metric. We also discuss how these results apply in different robustness exercises, including out-of-sample evaluations. Finally, we consider the potential role of market-based measures of bank capitalisation, showing that they provide complementary value to their accounting-based counterparts.
本文使用一种新颖的基于经验规则的方法来评估银行监管中多重要求的价值。利用2005年和2006年全球银行样本的资本和流动性比率数据集,我们应用简单的基于阈值的规则来评估不同的监管单独和组合如何识别随后在全球金融危机期间倒闭的银行。我们的研究结果总体上支持采用不同监管指标的小型投资组合。在正确识别大量随后倒闭的银行这一目标下,我们发现杠杆率、风险加权资本比率和净稳定融资比率的组合比这些指标中的任何一个单独产生的假警报都要少——而且对每个单独的监管指标的校准也不那么严格。我们还讨论了这些结果如何应用于不同的鲁棒性练习,包括样本外评估。最后,我们考虑了基于市场的银行资本化措施的潜在作用,表明它们为基于会计的同行提供了补充价值。

Exploiting a dataset of capital and liquidity ratios for a sample of global banks in 2005 and 2006, we apply simple threshold-based rules to assess how different regulations individually and in combination might have identified banks that subsequently failed during the global financial crisis. Our results generally support the case for a small portfolio of different regulatory metrics. Under the objective of correctly identifying a high proportion of banks which subsequently failed, we find that a portfolio of a leverage ratio, a risk-weighted capital ratio, and a net stable funding ratio yields fewer false alarms than any of these metrics individually – and at less stringent calibrations of each individual regulatory metric. We also discuss how these results apply in different robustness exercises, including out-of-sample evaluations. Finally, we consider the potential role of market-based measures of bank capitalisation, showing that they provide complementary value to their accounting-based counterparts.","PeriodicalId":376194,"journal":{"name":"ERN: Regulation & Supervision (Topic)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126790445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Basel III Accord tightens capital adequacy requirements for banks by increasing the minimum Tier 1 regulatory capital threshold from 4 to 6 percent. It also emphasizes the need to improve timeliness of loan loss provisions. Using a sample of European banks, we examine the impact of this regulation on banks’ discretionary loan loss provisioning behavior. Underscoring banks’ increased incentives to report higher capital ratios, we observe a post-Basel III increase in banks’ use of discretionary loan loss provisions (DLLPs) for capital management purposes and a corresponding reduction in the use of these provisions for income smoothing purposes. Moreover, we find that the timeliness of loan loss provisions has improved following Basel III. We also find that the post-Basel III increase in capital management behavior is greater for banks that do not face conflicting incentives when using DLLPs to improve Tier 1 versus total capital ratio. In contrast, the improvement in loan loss provisioning timeliness is greater for banks that are less likely to engage in capital management due to these conflicting incentives. Our findings suggest that Basel III has significantly altered banks’ discretionary loan loss provisioning behavior.
巴塞尔协议III通过将最低一级监管资本门槛从4%提高到6%,收紧了对银行的资本充足率要求。它还强调需要提高贷款损失准备金的及时性。本文以欧洲银行为样本,考察了这一规定对银行自主贷款损失拨备行为的影响。强调银行报告更高资本比率的动机增加,我们观察到巴塞尔协议III后银行用于资本管理目的的酌情贷款损失准备金(dllp)的使用增加,以及用于收入平滑目的的这些准备金的使用相应减少。此外,我们发现,在巴塞尔协议III之后,贷款损失准备金的及时性得到了改善。我们还发现,对于那些在使用dllp提高一级资本比率与总资本比率时没有面临冲突激励的银行来说,巴塞尔协议III后资本管理行为的增加更大。相比之下,对于那些由于这些相互冲突的激励而不太可能从事资本管理的银行来说,贷款损失准备及时性的改善更大。我们的研究结果表明,巴塞尔协议III显著改变了银行的任意贷款损失拨备行为。

Systems, Instruments and Regulatory Policies of American and European Capitalism 美国和欧洲资本主义的制度、工具和监管政策

The beginning of the 21st century, the phenomenon of globalization, the IT revolution and the financialization of the economy have also changed the terms of the comparison among capitalist countries. At global level, the rapid expansion of the financial sector was also encouraged by an increase in innovative financial products. Regulators and supervisors have not been able to adequately identify and address the growing risks in the financial system. The beginning of the financial crisis has brought to light such weaknesses. And it is from this negative experience that the major world authorities have intervened, trying to set up plans and regulations to protect the financial system and consumers. The analysis of the framework that comes with the financial crisis of 2007-2013 is thus a starting point for this work to understand the new features of world capitalism. American and European capitalist systems seem to diverge above all on the policies and instruments for regulating the financial system. The aim of the work is to show the differences between the US and European financial and banking regulation. The former is geared towards reviving deregulation and financial innovation while the latter is more geared towards redesigning a more accentuated regulatory model with a governance of the economy that always sees the presence of a mixed welfare and market system.
21世纪初,全球化现象、信息技术革命和经济金融化也改变了资本主义国家之间的比较条件。在全球一级,创新金融产品的增加也鼓励了金融部门的迅速扩张。监管机构未能充分识别和应对金融体系中日益增长的风险。金融危机的开始暴露了这些弱点。正是从这种负面经验中,世界主要当局进行了干预,试图制定计划和法规来保护金融体系和消费者。因此,对2007-2013年金融危机带来的框架的分析是理解世界资本主义新特征的起点。美国和欧洲的资本主义制度似乎主要在监管金融体系的政策和工具上存在分歧。这项工作的目的是展示美国和欧洲金融和银行监管之间的差异。前者旨在恢复放松管制和金融创新,而后者更倾向于重新设计一种更加强化的监管模式,其经济治理总是看到福利和市场体系的混合存在。
