Federal Reserve Governor Lisa Cook delivered a notable warning on Thursday regarding the potential implications of generative artificial intelligence on financial markets. Speaking at the McDonough School of Business at Georgetown University, she highlighted that emerging risks associated with AI trading systems could disrupt market dynamics. This perspective adds to the growing discourse surrounding the economic impacts of AI technologies, a topic that has seen increased attention from public officials in recent months.
Cook, who chairs the Fed board’s Committee on Financial Stability, expressed concerns that AI-driven trading algorithms may lead to market disarray through potential collusion or manipulation. While she acknowledged that research indicates the likelihood of such events is small, she cited recent theoretical studies that suggest these algorithms might learn to collude without any explicit coordination or intent. This phenomenon raises alarms about the preservation of competition and market efficiency.
“Recent theoretical studies find that some AI-driven trading algorithms can indeed learn to collude without explicit coordination or intent, potentially impairing competition and market efficiency,”
Cook stated.
She elaborated that AI trading systems have the capability to influence market behaviors. For example, she referred to a study revealing that self-learning algorithms could discover and implement spoofing strategies, where large orders are placed without intention of execution, creating artificial impressions of market demand.
Looking ahead, Cook warned that future AI systems might function with greater opacity, executing increasingly complex trades while effectively concealing manipulative intentions. The inherent lack of explainability in some sophisticated algorithms complicates regulatory and auditing processes. As she noted:
“There are growing concerns that results obtained from complex AI models may be difficult to explain or rationalize by human experts — the ‘black box’ problem. The inability to fully audit trades executed by algorithms makes surveillance by trading venues and regulators more challenging.”
Despite these concerns, Cook also emphasized a silver lining. She pointed out that advancements in AI technology could bolster market integrity and liquidity. “Thanks to improving surveillance capabilities, AI technology could ultimately strengthen market integrity and enhance market liquidity,” she stated. Furthermore, trading venues are taking proactive measures to mitigate risks associated with the ‘black box’ problem inherent in AI-enabled trading algorithms.
Other Federal Reserve officials are joining this discussion. Michael Barr and Christopher Waller have also commented on AI’s economic implications, particularly regarding the labor market. Barr noted in early November that certain roles may become obsolete due to AI advancements, although he remains optimistic about the overall impact. He suggested that while some short-term disruptions may occur, historical trends indicate that new job opportunities typically arise from technological advancements.
“I think even if there are some short-term dislocations, what we’ve seen with the introduction of technologies in the past is that over the long term, new jobs are created and jobs that exist change to be more productive for the worker,”
Barr remarked. “Workers get paid more, so it could increase real wages for people.”
Waller echoed this sentiment, asserting that the long-term economic benefits of AI will outweigh any immediate disruptions in the labor market.
Cook’s remarks come shortly after the Federal Reserve released its semiannual Financial Stability Report, which cautioned that excessive market optimism could pose risks to financial stability, especially if economic conditions shift. However, she reassured that the overall U.S. financial system remains “sound and resilient.”
As AI continues to evolve, the insights from Cook and her fellow Fed governors shed light on both the challenges and opportunities that these technologies present for financial markets. The need for vigilance and proactive measures will be crucial in navigating the complexities introduced by AI in trading environments.
