Project on Cyber Risk to Financial Stability
Fostering dialogue between academia, industry, and government to strengthen resilience to cyber risks within the financial sector.
Project on Cyber Risk to Financial Stability (CRFS)
The Project on Cyber Risk to Financial Stability, led jointly by the SIPA Cyber Program and the Initiative on Central Banking and Financial Policy, has worked to foster dialogue between experts in academia, industry, and government at the intersection of cybersecurity and financial stability to strengthen resilience in the financial industry. It is led by Jason Healey, director of SIPA Cyber and a senior research scholar at SIPA; and Patricia Mosser, director of the Initiative on Central Banking and Financial Policy and a senior research scholar and senior fellow at SIPA.
Since 2016, the project has hosted a series of engagements bringing together experts from financial institutions, the public sector including regulators and other policymakers, academics and practitioners with backgrounds in finance and cybersecurity. It has also published a number of publications and hosted two iterations of the annual Cyber Risk to Financial Stability: State of the Field Conference.
The Cyber Risks to Financial Stability Project team includes: Jason Healey, Director of the Cyber Program and Senior Research Scholar at SIPA; and Patricia Mosser, Director, MPA Program in Economic Policy Management; Director of the Initiative on Central Banking and Financial Policy and Senior Research Scholar and Senior Fellow at SIPA. It is supported by student researchers from Columbia SIPA.

The first virtual workshop on Cyber Risks to Financial Stability discussed the working paper Pirates without Borders: the Propagation of Cyberattacks through Firms’ Supply Chains by Matteo Crosignani, Marco Macchiavelli and André F Silva.
Abstract: We document the propagation through supply chains of the most damaging cyberattack in history and the important role of banks in mitigating its impact. Customers of directly hit firms saw reductions in revenues, profitability, and trade credit relative to similar firms. The losses were larger for customers with fewer alternative suppliers and suppliers producing high-specificity inputs. Internal liquidity buffers and increased borrowing, mainly through bank credit lines, helped affected customers maintain investment and employment. However, the shock led to persisting adjustments to the supply chain network.

The third virtual workshop on Cyber Risks to Financial Stability discussed the working paper The Anatomy of Cyber Risk by Rustam Jamilov, Hélène Rey, Ahmed Tahoun.
Abstract: This paper uses computational linguistics to introduce a novel measure of firm-level cyber-risk exposure based on quarterly earnings conference calls of listed firms. Our data span 13,000 firms from 85 countries over 2002-2021. We show cyber-risk exposure predicts cyber-attacks, affects stock returns and profits, and is priced in the equity option market. Cyber-risks spill over across firms and pass through from firm to sectoral level. The geography of cyber-risk is well approximated by a gravity model in which financial proximity is key. Back-of-the-envelope calculations suggest that the global cost of cyber-risk is over $200 billion per year.

The fourth virtual workshop on Cyber Risks to Financial Stability discussed the paper Financial Markets and Social Media: Lessons From Information Security by Claudia Biancotti and Paolo Ciocca.
Abstract: Discourse on social media increasingly affects personal financial decisions. This may improve market efficiency, yet it may also provide malicious actors with opportunities for disinformation and disruption. Financial authorities, governments, and other stakeholders must work together to counter this threat.

The fifth virtual workshop on Cyber Risks to Financial Stability discussed the paper Cyberattacks and Financial Stability: Evidence from a Natural Experiment by Antonis Kotidis and Stacey L. Schreft.
Abstract: This paper studies the effects of a unique multi-day cyberattack on a technology service provider (TSP). Using several confidential daily datasets, we identify and quantify first- and second-round effects of the event. For banks using relevant services of the TSP, the attack impaired their ability to send payments over Fedwire, even though the Federal Reserve extended the time they had to submit payments. This impairment (first-round effect) caused other banks to receive fewer payments (second-round effect), leaving them at risk of having too few reserves to send their own payments (a potential third-round effect). These innocent-bystander banks responded differently depending on their size and reserve holdings. Those with sufficient reserves drew down their reserves. Of the others, smaller banks borrowed from the discount window, while larger banks borrowed in the federal funds market. These significant adjustments to operations and funding prevented the second-round effect from spilling over into third-round effect and broader financial instability. These findings highlight the important role for bank contingency planning, liquidity buffers, and the Federal Reserve in supporting the financial system’s recovery from a cyberattack.

The sixth virtual workshop on Cyber Risks to Financial Stability discussed the paper When It Rains, It Pours: Cyber Risk and Financial Conditions by Thomas M. Eisenbach, Anna Kovner, and Michael Junho Lee
Abstract: We analyze how systemic cyber risk in the wholesale payments network relates to adverse financial conditions. We show that at the onset of the COVID-19 pandemic, payment activity increased, became more concentrated, and showed intraday liquidity stress. Cyber vulnerability was elevated in late February and early March 2020, with the potential impact of a cyberattack about 40 percent greater than in the remainder of 2020. Policy interventions to stabilize markets mitigated cyber vulnerability, particularly corresponding to large increases in aggregate reserves. We observe that cyber vulnerability and other financial shocks cannot be treated as uncorrelated risks and policy solutions for cyber security need to be calibrated for adverse financial conditions.

The seventh virtual workshop on Cyber Risks to Financial Stability discussed the book Cyber and the City: Securing London's Banks in the Computer Age by Dr. Ashley Sweetman.
Abstract: This book presents the first history of computer security in finance, from the perspective of the banks. It offers a mixture of broad overview chapters that set the scene, alongside more detailed case-study chapters. The chapters provide insights from unseen/unused archival material from various banks, and the London Metropolitan Archives

The eighth virtual workshop on Cyber Risks to Financial Stability discussed the working paper Cyber Security and Ransomware in Financial Markets by Toni Ahnert, Michael Brolley, David Cimon and Ryan Riordan
Abstract: Financial markets face the constant threat of cyber attacks. We develop a principal-agent model of cyber-attacking with fee-paying clients who delegate security decisions to financial platforms. We derive testable implications about clients’ vulnerability to cyber attacks and about the fees charged. We characterize which cyber attacks actors choose. We find that ransomware attacks are more successful than traditional attacks and that platforms underinvest in security when security is unobservable. Regulating security investment (e.g., minimum security standards) or improving transparency (e.g., security ratings) can improve welfare. Our results support regulatory efforts to increase transparency around cyber security and cyber attacks.

The ninth virtual workshop on Cyber Risks to Financial Stability discussed the working paper City Hall Has Been Hacked! The Financial Costs of Lax Cybersecurity by Filippo Curti, Ivan Ivanov, Marco Macchiavelli, and Tom Zimmermann.
Abstract: State and local governments are attractive cybercrime targets because of inadequate cybersecurity and ample access to sensitive information. We show that external data breaches translate to higher financing costs for governments including negative abnormal bond returns in the secondary market and higher offering yields and bond pricing uncertainty in the primary market. We also find that governments increase total spending around cyberattacks, suggesting higher operating costs as the likely channel behind the spike in financing costs. Exploiting state-level variation in the timing of breach notification laws, we show that they have not significantly strengthened cybersecurity.
Discussion Summary: This paper contributes to the ongoing struggle of how cybersecurity plays into understanding of financial stability, propagation of shocks, and pricing of risks.
Cybercrime costs billions of dollars to businesses and the government each year. The cyber criminals monetize cyber vulnerabilities through different vectors however, this paper focuses on data breach specifically with some mention of ransomware. Municipalities are good targets for cybersecurity since they have large amounts of data that are PIIs and inadequate cybersecurity.
The effect of data breaches on municipalities is that after the breach, it leads to 1) increase in financing costs. There are negative abnormal bond returns in the secondary market and higher offering yield at issuance for the primary market. 2) There is an increase in expenditures after breach such as significant remediation and litigation costs. This can mean that there is a room for regulations. However, since 2002, starting with California, until 2021, states have implemented data breach notification laws. Some impose penalties in case of violations. These regulations are found to be ineffective at strengthening cybersecurity posture as there is no effect on incidence of future data breaches though there is a slight increase in expenditure following the implementation of the regulation.
Some of the items discussed for future research include measure of vulnerability by states, geographical spillover effect of data breach incidents, standards on what decent cyber defenses are, impact on different bonds based on different cybersecurity incidents (data breach vs ransomware), relation between those increasing expenditure and ones with large financing cost, consideration of revenue and population for targeted municipalities and others.

The tenth virtual workshop on Cyber Risks to Financial Stability discussed the paper The Supply of Cyber Risk Insurance by Martin Eling, Anastasia V. Kartasheva, and Dingchen Ning
Abstract: Cyber risk insurance has been introduced for more than two decades in the United States, yet the insurance market for cyber risk is tiny amounting to 1% ($6.5 billion) of premiums in the U.S. property-casualty insurance market in 2021. In this paper, we analyze what constrains the insurance industry from providing larger capacity. We argue that cyber risk is special in that it is both information-intensive to underwrite and heavy-tailed. It leads to the tension between the need to raise large amounts of external capital to finance heavy-tailed risks and the high compensation demanded by capital providers due to information frictions. Hence, the suppliers are large insurance groups with a deep internal capital market, and their capacity is constrained. We start by providing empirical evidence that the cyber risk insurance market is dominated by large insurance groups and that, compared to other types of insurance, cyber insurance relies heavily on the groups' internal capital market. Then, using an exogenous shock on the tax treatment of the non-U.S. affiliated reinsurance in 2017, we establish the causal inference that insurers primarily rely on the internal capital market to supply cyber risk insurance.
Discussion Summary: Cyber risk is becoming a major concern with considerable uncertainty. There are not a lot of discussions around transferring the risk through traditional financial institutions such as insurance. The cyber insurance market is growing however, the premium is very small in the insurance market. This raises the question: what are the supply-side factors that curtail the development of the cyber insurance market? The research finds that the supply of cyber insurance depends on the internal capital market. The insurance groups with large capital markets dominate the market as there is a significant correlation between cyber insurance supply and the reliance of affiliated reinsurance. Moreover, heavy tails, information asymmetry, and risk certainty are characteristics of cyber risk that limit insurers from raising external capital to support the supply of cyber insurance. The impact of cyber lines on the profitability of other lines and entry and exit decisions in the cyber insurance market remain as next steps.
The participants engaged in lively discussions around characteristics of other insurance vs cyber insurance, incentives for attackers, calculation methods for losses and size effects of cyber insurance.
