Designing Financial Agents: Architectures, Ethics, and Institutional Impact

Abstract

Financial agents powered by artificial intelligence are rapidly transforming markets, institutions, and decision-making processes. This article examines the design of financial agents through three interconnected dimensions: technical architecture, ethical governance, and institutional impact. First, it surveys architectural paradigms—including rule-based systems, reinforcement learning models, multi-agent frameworks, and large language model–driven agents—highlighting trade-offs in autonomy, interpretability, robustness, and scalability. Second, it analyzes ethical considerations such as transparency, fairness, accountability, systemic risk amplification, and alignment with regulatory frameworks. Special attention is given to the challenges of explainability in high-stakes financial contexts and the governance mechanisms required to mitigate bias and prevent market manipulation. Third, the article explores institutional consequences, including shifts in organizational structures, labor dynamics, compliance practices, and market stability. It argues that financial agents are not merely technical tools but socio-technical actors embedded within regulatory and economic systems. The paper concludes by proposing a design framework that integrates modular technical architectures, embedded ethical safeguards, and institutional co-design principles to ensure that financial agents enhance efficiency and innovation while preserving trust, stability, and public accountability.
