The Dangerous Illusion Of Explainable AI In Modern Finance, Forbes. Finance has always rested on a simple moral contract. When decisions affect people’s money, homes and futures, someone must be able to explain why those decisions were made. That principle once lived in credit committees, underwriting manuals and human judgment. Today, it’s being handed to machines. To make that shift feel safe, the industry has wrapped AI in the language of transparency. Banks tell regulators that their models are explainable. Vendors sell dashboards that promise insight. Boards are assured that nothing essential is hidden. The message is that advanced AI and accountability can coexist. In practice, this promise no longer holds. The systems driving modern finance aren’t linear scorecards or rule-based engines. They’re deep neural networks, ensemble models and continuously learning systems trained on thousands of interacting variables. These machines don’t reason in steps that resemble human logic. They detect statistical patterns across vast data landscapes that have no simple causal story attached to them. What’s called explainable AI is an attempt to make this machinery appear legible. A secondary model is trained to imitate the primary one and then asked to generate feature attributions or importance scores. These outputs are turned into reports that look like reasons, but they aren’t. They’re approximations of correlations inside a system that has no concept of why. This matters because financial decisions rarely come from a single model. A mortgage, a credit limit or a fraud alert emerges from a network of engines assessing income stability, spending behavior, credit history, transaction risk and portfolio exposure. Each is trained on different data and optimized for different objectives. Their outputs combine into a final judgment that no individual can truly reconstruct, even if every piece were interpretable on its own. Yet the industry presents it as if it were. Regulators are shown model cards, fairness metrics and compliance narratives that offer a clean story of control. These artifacts aren’t fabrications, but they aren’t the truth, either. They describe how an approximation behaves, not how the system actually operates at scale. Inside large financial institutions, this gap is quietly understood. Model developers know that explainability tools are fragile. They change when models are retrained. They drift as data shifts. They give different answers depending on how the question is framed…
Companies including Palantir and Deloitte have collectively reaped more than $22bn from contracts linked to Donald Trump’s immigration crackdown. Financial Times, January 29, 2026. The “surprisingly resilient” global economy is at risk of being disrupted by a sharp reversal in the AI boom, the IMF warned on Monday, as world leaders prepared for talks in the Swiss resort of Davos. Risks to global economic expansion were “tilted to the downside”, the fund said in an update to its World Economic Outlook, arguing that growth was reliant on a narrow range of drivers, notably the US technology sector and the associated equity boom. Nonetheless, it predicted US growth would strongly outpace the rest of the G7 this year, forecasting an expansion of 2.4 per cent in 2026 and 2 per cent in 2027. Tech investment had surged to its highest share of US economic output since 2001, helping drive growth, the IMF found. “There is a risk of a correction, a market correction, if expectations about AI gains in productivity and profitability are not realised,” said Pierre-Olivier Gourinchas, IMF chief economist. “We’re not yet at the levels of market frothiness, if you want, that we saw in the dotcom period,” he added. “But nevertheless there are reasons to be somewhat concerned.”
The FCA has launched a review into the implications of advanced AI on consumers, retail financial markets and regulators. UK financial Conduct Authority, January 27, 2026. The Review will be led by Sheldon Mills and builds on the FCA’s existing work on AI. This includes its AI Discussion Paper, AI Sprint, and AI Lab including AI Live Testing and its groundbreaking Supercharged Sandbox supported by NVIDIA. AI is already embedded across financial services. Rapid advances in generative, agentic and emerging forms of AI mean the next phase of change could be profound, having the power to reshape markets, change the way firms compete and how consumers use retail financial services. Sheldon Mills said: ‘AI is already shaping financial services, but its longer-term effects may be more far-reaching. This review will consider how emerging uses of AI could influence consumers, markets and firms, looking towards 2030 and beyond. ‘By taking a forward-looking view, the review will help the FCA continue to support innovation while promoting the safe and trusted adoption of AI in retail financial services.’
The FCA is seeking views on 4 interrelated themes:
- How AI could evolve in the future, including the development of more autonomous and agentic systems.
- How these developments could affect markets and firms, including changes to competition and market structure and UK competitiveness.
- The impact on consumers, including how consumers will be influenced by AI but also influence financial markets through new expectations.
- How financial regulators may need to evolve to continue ensuring that retail financial markets work well.
While wholesale markets and broader societal impacts are out of scope, the Review recognises that developments in these areas may indirectly influence retail financial services and will be considered where relevant. The FCA is also separately doing extensive work on the impact of AI in wholesale markets, in particular through our live testing partnership. Feedback will shape a series of recommendations to be reported to the FCA Board in summer 2026, informing how the FCA can guide and respond to AI-driven transformation. This will culminate in an external publication..
- The engagement paper sets out the scope of the review and invites views from stakeholders including firms, consumer groups, tech providers and academics on 4 key themes.
- The FCA’s approach to artificial intelligence is grounded in its principles-based regulatory framework, including the Consumer Duty. This ensures outcomes-focused regulation that supports innovation while safeguarding consumers.
- The FCA launched its AI Lab in 2024 to deepen understanding of AI technologies and their implications for financial services. The Lab works with industry, academia, and other regulators to explore responsible AI adoption.
- This work forms part of the FCA’s wider commitment to leading thinking globally on the responsible adoption of advanced technologies in financial services, and to ensuring that the UK remains a trusted, competitive and resilient financial centre in the age of AI.
- The FCA does not plan to introduce AI-specific regulation. It will continue to rely on its existing, principles-based regulatory framework while considering how regulators need to evolve as AI becomes more embedded in financial services.

Why BlackRock’s Larry Fink wants the entire financial system on ‘one common blockchain‘, DL News. January 22, 2026. Tokenisation will reduce fees and democratise finance, according to BlackRock CEO Larry Fink. Updating the financial system to run on blockchain technology is “necessary,” and promises to slash fees and boost accessibility for investors. That’s the case BlackRock CEO Larry Fink made while speaking on a World Economic Forum panel in Davos, Switzerland on Wednesday alongside Citadel CEO Ken Griffin and European Central Bank President Christine Lagarde. Tokenisation is the process of converting ownership rights of assets like real estate, stocks, or bonds into digital tokens on a blockchain. Proponents argue doing so will speed up finance, reduce costs and provide more accountability. “We would be reducing fees, we would do more democratisation,” Fink said. “[If] we have one common blockchain, we could reduce corruption.” For Wall Street titans like BlackRock, tokenisation presents a huge opportunity. Much of the core underlying software the global financial system runs on is between 40 and 60 years old. Because of this, it is often clunky and slow, and depends on costly intermediaries. Updating it to a blockchain-based system could make those who pioneer the change a lot of money. BlackRock isn’t the only one who’s bullish on blockchains. “Blockchain is the future for traditional banking,” said Sergio Ermotti, CEO of UBS, at the World Economic Forum earlier this week. “You will see a convergence.” The head of the world’s largest wealth manager just said blockchain’s convergence with traditional banking is inevitable. Ripple and Boston Consulting Group predict blockchain tokenisation will swell into a $19 trillion industry by 2033, while asset manager Grayscale forecasts a thousand-fold growth of tokenised assets, pushing their combined value to $35 trillion by 2030.

PAPERS:
Speculative Growth and the AI “Bubble.” Working Paper 34722. DOI 10.3386/w34722. Issue Date. AI technology can generate speculative-growth equilibria. These are rational but fragile: elevated valuations support rapid capital accumulation, yet persist only as long as beliefs remain coordinated. Because AI capital is labor-like, it expands effective labor and dampens the normal decline in the marginal product of capital as the capital stock grows. The gains from this expansion accrue disproportionately to capitalists, whose saving rate rises with wealth, raising aggregate saving. Building on Caballero et al (2006), I show that these features generate a funding feedback—rising capitalist wealth lowers the required return—that can produce multiple equilibria. With intermediate adjustment costs, elevated valuations are the mechanism that sustains a transition toward a high-capital equilibrium; a loss of confidence can precipitate a self-fulfilling crash and reversal.
Does Generative AI Crowd Out Human Creators? Evidence from Pixiv. Sueyoul Kim, Ginger Zhe Jin, Eungik Lee. Working Paper 34733. DOI 10.3386/w34733. Issue Date January 2026. Using a comprehensive dataset of posts from a major platform for anime- and manga-style artwork, we study the impact of the launch of a prominent text-to-image generative AI. Focusing on the majority of incumbent creators who do not adopt AI as a primary tool, we show that the AI launch led to a significant decline in post uploads by illustrators, whereas comic artists were less affected, reflecting the need for tight stylistic alignment across sequential images in comics. We present empirical evidence for two underlying mechanisms. First, illustration posts experience a loss of viewer attention, measured by bookmarks, following the AI launch, which can significantly harm creators’ business models. Second, direct competition from AI-generated content plays an important role: illustrators working on intellectual properties (IPs, such as Pokémon) that are more heavily invaded by AI reduce their uploads disproportionately more. We further examine creators’ responses and show that illustrators with greater exposure to AI avoid using tags favored by AI-generated content after the AI launch and broaden the range of IPs they work on, consistent with a risk-hedging response to AI invasion.
Behavioral Economics of AI: LLM Biases and Corrections. Working Paper 34745. DOI 10.3386/w34745. Issue Date January 2026. Do generative AI models, particularly large language models (LLMs), exhibit systematic behavioral biases in economic and financial decisions? If so, how can these biases be mitigated? Drawing on the cognitive psychology and experimental economics literatures, we conduct the most comprehensive set of experiments to date—originally designed to document human biases—on prominent LLM families across model versions and scales. We document systematic patterns in LLM behavior. In preference-based tasks, responses become more human-like as models become more advanced or larger, while in belief-based tasks, advanced large-scale models frequently generate rational responses. Prompting LLMs to make rational decisions reduces biases.
