#AI ChatGPT – OpenAI: Assigning too much power to some few (human fallible) credit rating agencies, does that not introduce a systemic risk?
I asked OpenAI:
"Assigning so much power to some few (human fallible) credit rating agencies to determine how much capital a bank needs to hold against assets, could that be regarded as introducing a systemic risk?"
OpenAI answered:
"Assigning significant power to credit rating agencies in determining capital requirements for banks can introduce certain risks, including the potential for systemic risk. Here are some considerations:
1. Concentration of Power: Relying heavily on a few credit rating agencies concentrates significant power in their hands. This concentration can lead to a lack of diversity in risk assessment methodologies and potential biases in credit ratings. If these agencies make errors or fail to accurately assess risks, it can have far-reaching consequences for the banking system and broader economy.
2. Herding Behavior and Pro-Cyclicality: Reliance on credit rating agencies can contribute to herding behavior among market participants. If multiple institutions rely on the same set of ratings, it can amplify market movements and contribute to pro-cyclical dynamics. During periods of market stress, widespread downgrades or rating adjustments by credit rating agencies can exacerbate systemic risks and market volatility.
3. Overreliance on Ratings: Assigning excessive importance to credit ratings can lead to overreliance on these assessments by market participants, including banks, investors, and regulators. Overreliance can create a false sense of security and reduce incentives for independent risk assessment, potentially overlooking underlying risks and vulnerabilities in the banking system.
4. Limited Transparency and Accountability: The methodologies and criteria used by credit rating agencies are not always transparent or readily accessible. This lack of transparency can hinder market participants' ability to fully understand and assess the accuracy and reliability of the credit ratings. It also limits the agencies' accountability for their ratings and decisions.
5. Regulatory Capture and Conflicts of Interest: There is a risk of regulatory capture or conflicts of interest when credit rating agencies have close relationships with the institutions they rate. These relationships can potentially compromise the objectivity and independence of the ratings, raising concerns about the accuracy and reliability of the assessments.
To mitigate these risks, regulators and policymakers have implemented measures to enhance the oversight and regulation of credit rating agencies. This includes improving transparency, encouraging competition among rating agencies, promoting independent risk assessment within banks, and diversifying the sources of credit analysis.
Additionally, efforts are underway to explore alternative methods of risk assessment and capital requirements, such as stress testing, internal risk models, and broader consideration of risk factors beyond credit ratings alone."

PS. More than two decades ago, at the World Bank. "Nowadays, when information is just too voluminous and fast to handle, market or authorities have decided to delegate the evaluation of it into the hands of much fewer players such as the credit rating agencies. This will, almost by definition, introduce systemic risks in the market"
