In today’s hyperconnected financial landscape, identity is the new perimeter. And attackers know it. GlobalData – April 14, 2025. Artificial intelligence is accelerating identity-based cyberattacks, allowing fraudsters to exploit stolen credentials, automate phishing, and bypass traditional defenses faster than ever. For banks and credit unions, this shift marks a critical moment. To protect customer trust and financial assets, security teams must evolve just as quickly – or risk becoming prime targets. Identity is the new currency of cybercrime – Customer login credentials, privileged access tokens, biometric records, and personally identifiable information (PII) are now among the most valuable assets in a cybercriminal’s arsenal. These identity-related assets are increasingly accessible via data breaches and dark web marketplaces. AI makes them even more dangerous by enabling real-time analysis, correlation, and exploitation. In the financial sector, this means attackers can hijack active single sign-on (SSO) tokens, bypassing standard login protocols entirely. AI-powered brute force and credential spraying tools can crack weak or reused passwords in seconds. Even more troubling, AI-driven phishing and social engineering tactics can convincingly impersonate bank representatives, tricking customers into handing over sensitive information or access to their accounts. The 23andMe breach demonstrated just how far attackers will go to exploit identity data, using credential reuse and social engineering to access genetic and financial data. Financial institutions must prepare for similar tactics being used to target retail banking customers. AI is supercharging cybercrime — here’s how financial institutions can stay ahead…


Tariffs, Trump and AI Are Changing Everything. Should My Portfolio Change Too? And what about my career? Or retirement plans? Three experts weigh in on how to adjust to uncertain times [no paywall]. Bloomberg, April 13, 2025. AI can be so useful. I’m bummed that our first instinct is to use it to replace art and music and all of the things that make being a human good. I don’t think that’s a wise thing to do. That’s such a small part of GDP. There’s a meme: “I wanted my AI to do laundry and dishes so I could make art. Now AI is making art, and I have to do the laundry and wash the dishes.”…With AI, we have this tech that could totally displace people. McKinsey & Co. imagines it’ll displace about half of work activities. There are valid reasons to be afraid. I think the solution to that, again, is having some sort of ­investment—to have some sort of stability, to try and save money as you can—and to build out your skill set.


Computer Weekly, April 10, 2025. Lloyds Bank moves AI work onto Google Cloud platform. Banking group is cutting its emissions and accelerating the development of AI platforms by moving work onto Google Cloud. Lloyds Banking Group will build, deploy and scale artificial intelligence (AI) systems using a Google service, accelerating production while slashing CO2 emissions. The bank is using Google Cloud’s Vertex AI to build a machine learning (ML) and generative artificial intelligence (GenAI) development platform, which more than 300 of its data scientists will use. During the migration to the Google Cloud platform, 15 modelling systems were moved, which included hundreds of AI models, from on-premise systems. Lloyds Bank said this saved 27 tonnes of operational emissions. Ranil Boteju, chief data and analytics officer at Lloyds Banking Group, said: “Moving to Vertex AI has been transformative for us as a Group, providing us with the scalability and reliability to innovate with AI at pace. Vertex AI is enabling data scientists and AI developers across the Group to access GenAI solutions with consistent guardrails, as well as giving them the flexibility to use large language models [LLMs] from third parties and open source providers, as well as Google’s Gemini model.”

PAPERS:

Measuring and Building Human Leadership in an AI World By Brent Orrell | Raphaël Colard AEIdeas April 09, 2025: “A new working paper from the National Bureau of Economic Research, Measuring Human Leadership Skills With AI Agents, presents evidence that artificial intelligence may soon play a central role in evaluating human soft skills—long considered too complex and subjective to measure objectively. Conducted by Ben Weidmann and David Deming et al. at the Harvard Kennedy School, the study involved 249 participants who led teams of both human and AI-agent teams through collaborative problem-solving tasks. To measure leadership, the researchers used a “hidden profile task,” where critical information was distributed unevenly among teammates and must be discovered and identified by the leader. Those who succeeded—whether leading AI agents or humans—tended to ask more questions, promote turn-taking in conversation, and use plural pronouns, like “we” and “us.” The findings are striking: leadership skills demonstrated with AI teammates closely mirror leadership effectiveness with human teams, with a strong correlation of 0.81 between the two tests. As opposed to coming from formal credentials, strong leadership springs from behavioral patterns that foster collaboration—a type of socio-emotional IQ called noncognitive skills. Since the study finds these types of skills are unrelated to race, gender and other identity categories, use of AI may afford opportunities for more people of all backgrounds to discover and develop leadership abilities. Moreover, the emerging reality that AI will increasingly take over narrow technical tasks is likely to raise the premium on social-emotional skills. A world that demands more of such skills may disproportionately benefit the socially agile relative to the technically gifted.  The study’s insights would also be useful in improving leadership hiring, training, and evaluation. Organizations could move beyond static resumes and subjective interviews toward dynamic, performance-based assessments that reflect how people lead in real time. Training programs could be better targeted, focusing on developing the communication habits and social reasoning that matter most. There is already evidence that AI is adept at training humans in leadership skills, as demonstrated by research on call center workers and a new pilot program for training substance abuse counselors…”


How Good is AI at Twisting Arms? Experiments in Debt Collection. James J. Choi, Dong Huang, Zhishu Yang & Qi Zhan. NBER Working Paper 33669. DOI 10.3386/w33669. Issue Date How good is AI at persuading humans to perform costly actions? We study calls made to get delinquent consumer borrowers to repay. Regression discontinuity and a randomized experiment reveal that AI is substantially less effective than human callers. Replacing AI with humans six days into delinquency closes much of the gap. But borrowers initially contacted by AI have repaid 1% less of the initial late payment one year later and are more likely to miss subsequent payments than borrowers who were always called by humans. AI’s lesser ability to extract promises that feel binding may contribute to the performance gap.


AI as Strategist. Joshua S. Gans. NBER Working Paper 33650. DOI 10.3386/w33650. Issue Date This paper examines the role of artificial intelligence as a strategist in organizational decision-making by extending van den Steen’s formal theory of strategy. A mathematical model is developed comparing AI and human strategists across different decision contexts, focusing on how each type generates confidence, achieves agreement, and implements decisions through control versus influence. The analysis presumes that AI excels in data-rich domains but faces credibility challenges in judgment-intensive contexts, creating a counterintuitive result where AI requires less formal authority precisely where it demonstrates superior analytical capabilities. The paper identifies distinct mechanisms through which strategic value is created: direct decision quality improvement and enhanced coordination. The authors propose domain-contingent approaches to AI integration, including differentiated authority systems across decision types and progressive control models that evolve as AI demonstrates effectiveness. These findings contribute to strategy theory while providing practical guidance for organizations seeking to effectively integrate AI into strategic processes, highlighting that organizations must adapt to their strategists’ capabilities as much as strategists must match their organizations.


How Much Should We Spend to Reduce A.I.’s Existential Risk? Charles I. Jones. NBER Working Paper 33602. DOI 10.3386/w33602. Issue Date During the Covid-19 pandemic, the United States effectively “spent” about 4 percent of GDP — via reduced economic activity — to address a mortality risk of roughly 0.3 percent. Many experts believe that catastrophic risks from advanced A.I. over the next decade are at least this large, suggesting that a comparable mitigation investment could be worthwhile. Existing lives are valued by policymakers at around $10 million each in the United States. To avoid a 1% mortality risk, this value implies a willingness to pay of $100,000 per person — more than 100% of per capita GDP. If the risk is realized over the next two decades, an annual investment of 5% of GDP toward mitigating catastrophic risk could be justified, depending on the effectiveness of such investment. This back-of-the-envelope intuition is supported by the model developed here. In the model, for most of the scenarios and parameter combinations considered, spending at least 1% of GDP annually to mitigate AI risk can be justified even without placing any value on the welfare of future generations.


Chen, Binkai and Guo, Dongmei and Xia, Junjie and Zhang, Zirun, The Transformative Role of Artificial Intelligence and Big Data in Banking (April 12, 2025). Available at SSRN: https://ssrn.com/abstract=5120308 or http://dx.doi.org/10.2139/ssrn.5120308 – This study examines the impact of artificial intelligence (AI) and big data on the banking sector, leveraging a comprehensive dataset of over 4.5 million loans issued by a major commercial bank in China between 2015 and 2023. Using a policy mandate to adopt AI and big data as an exogenous shock, our analysis reveals that the integration of these technologies significantly enhances credit rating accuracy and reduces loan default rates, particularly benefiting small and medium-sized enterprises. Specifically, the rate of undetermined credit ratings decreases by 2.4 percentage points (a 40.1% reduction), and loan default rates decline by 2.7 percentage points (a 29.6% reduction). By analyzing the timeline of the bank’s adoption of different technologies, we find that integrating big data with AI models and recognition technologies has a more profound impact than traditional FinTech models. Our findings highlight the informational advantages of AI and big data and their role in enhancing operational efficiency, improving risk management capabilities, and promoting financial inclusion for small businesses in financial institutions.

Chaudhari, Saurav, Artificial Intelligence in Investment Banking Transforming Operations and Client Services (February 10, 2025). Available at SSRN: https://ssrn.com/abstract=5130872 or http://dx.doi.org/10.2139/ssrn.5130872  – Artificial Intelligence (AI) is revolutionizing investment banking by transitioning from traditional, human judgment-based methods to data-driven decision-making. The integration of AI enhances operations, risk management, and customer experience, reshaping the industry’s competitive landscape. Financial institutions like JPMorgan Chase and Morgan Stanley have successfully implemented AI for risk assessments and personalized investment advice. While AI offers numerous advantages, it also presents challenges, such as data privacy concerns, regulatory compliance, and ethical implications. As AI evolves, its role in investment banking is expected to grow, offering significant opportunities for innovation and operational efficiency, necessitating a balanced approach to governance and ethical considerations.
