Cyber Risk Market Failures And Financial Stability

Cyber-attacks on financial institutions and financial market infrastructures are becoming more common and more sophisticated. Risk awareness has been increasing, firms actively manage cyber risk and invest in cybersecurity, and to some extent transfer and pool their risks through cyber liability insurance policies. This paper considers the properties of cyber risk, discusses why the private market can fail to provide the socially optimal level of cybersecurity, and explore how systemic cyber risk interacts with other financial stability risks. Furthermore, this study examines the current regulatory frameworks and supervisory approaches, and identifies information asymmetries and other inefficiencies that hamper the detection and management of systemic cyber risk. The paper concludes discussing policy measures that can increase the resilience of the financial system to systemic cyber risk.

The ability of attackers to undermine, disrupt and disable information and communication technology systems used by financial institutions is a threat to financial stability and one that requires additional attention.

Cyber risk has emerged as a key threat to financial stability, following recent attacks on financial institutions. This paper presents a novel documentation of cyber risk around the world for financial institutions by analyzing the different types of cyber incidents (data breaches, fraud and business disruption) and identifying patterns using a variety of datasets. The other novel contribution that is outlined is a quantitative framework to assess cyber risk for the financial sector. The framework draws on a standard VaR type framework used to assess various types of stability risk and can be easily applied at the individual country level. The framework is applied in this paper to the available cross-country data and yields illustrative aggregated losses for the financial sector in the sample across a variety of scenarios ranging from 10 to 30 percent of net income.

This paper highlights the emerging supervisory practices that contribute to effective cybersecurity risk supervision, with an emphasis on how these practices can be adopted by those agencies that are at an early stage of developing a supervisory approach to strengthen cyber resilience. Financial sector supervisory authorities the world over are working to establish and implement a framework for cyber risk supervision. Cyber risk often stems from malicious intent, and a successful cyber attack—unlike most other sources of risk—can shut down a supervised firm immediately and lead to systemwide disruptions and failures. The probability of attack has increased as financial systems have become more reliant on information and communication technologies and as threats have continued to evolve.

This paper discusses the impact of the rapid adoption of artificial intelligence (AI) and machine learning (ML) in the financial sector. It highlights the benefits these technologies bring in terms of financial deepening and efficiency, while raising concerns about its potential in widening the digital divide between advanced and developing economies. The paper advances the discussion on the impact of this technology by distilling and categorizing the unique risks that it could pose to the integrity and stability of the financial system, policy challenges, and potential regulatory approaches. The evolving nature of this technology and its application in finance means that the full extent of its strengths and weaknesses is yet to be fully understood. Given the risk of unexpected pitfalls, countries will need to strengthen prudential oversight.

"The rising number of cyber attacks in the financial sector poses a threat to financial stability and makes cyber risk a key concern for policy makers. This paper presents the results of a survey among members of the Global Cyber Resilience Group on cyber risk and its challenges for central banks. The survey reveals that central banks have notably increased their cyber security-related investments since 2020, giving technical security control and resiliency priority. Central banks see phishing and social engineering as the most common methods of attack, and the potential losses from a systemically relevant cyber attack are deemed to be large, especially if the target is a big tech providing critical cloud infrastructures. Generally, respondents judge the preparedness of the financial sector for cyber attacks to be inadequate. While central banks in most emerging market economies provide a framework for the collection of information on cyber attacks on financial institutions, less than half of those in advanced economies do. Cooperation among public authorities, especially in the international context, could improve central banks’ ability to respond to cyber attacks."--Abstract.

Financial technology (fintech) is emerging as an innovative way to achieve financial inclusion and the broader objective of inclusive growth. Thus far, fintech in the MENAP and CCA remains below potential with limited impact on financial inclusion. This paper reviews the fintech landscape in the MENAP and CCA regions, identifies the constraints to the growth of fintech and its contribution to inclusive growth and considers policy options to unlock the potential.

This Financial System Stability Assessment paper discusses that Canada has enjoyed favorable macroeconomic outcomes over the past decades, and its vibrant financial system continues to grow robustly. However, macrofinancial vulnerabilities—notably, elevated household debt and housing market imbalances—remain substantial, posing financial stability concerns. Various parts of the financial system are directly exposed to the housing market and/or linked through housing finance. The financial system would be able to manage severe macrofinancial shocks. Major deposit-taking institutions would remain resilient, but mortgage insurers would need additional capital in a severe adverse scenario. Housing finance is broadly resilient, notwithstanding some weaknesses in the small non-prime mortgage lending segment. Although banks’ overall capital buffers are adequate, additional required capital for mortgage exposures, along with measures to increase risk-based differentiation in mortgage pricing, would be desirable. This would help ensure adequate through-the cycle buffers, improve mortgage risk-pricing, and limit procyclical effects induced by housing market corrections.
