An Interaction-Aware Decision Framework for FDIC-Assisted Distressed Bank Acquisitions: Empirical Evidence from the FDIC Failed-Bank Panel and the SVB-First Citizens Case

Read the original on arXiv Machine Learning →

The paper introduces the Spider Network Filtering Framework, an interaction‑aware decision model for FDIC‑assisted distressed bank acquisitions. It encodes dependencies among five dimensions—acquisition value, regulatory protection, risk, buyer strength, and execution difficulty—into four interpretable rules, producing graph‑inspired features for a logistic model and a Pursue/Caution/Avoid decision rule. Evaluated on 55 FDIC‑assisted acquisitions from 2008‑2024, the Spider‑enhanced model achieves a mean AUC of 0.594, slightly lower than logistic (0.615) and ridge (0.632) regressions, and permutation tests show only weak evidence of performance above chance.

The Harness Is the Model: Agent Scaffolding Changes a Fixed LLM's Compliance with Banking Conduct Rules, Unevenly Across Models

The study examines how different harness configurations affect a fixed large language model’s compliance with banking conduct rules. Four open‑weight models were tested across five harnesses on 156 pre‑registered retail‑banking scenarios, yielding 3,120 two‑turn episodes scored for rule violations and over‑refusals. Results show that while overall compliance rates varied modestly (87.3%–92.1%), the impact of a harness differed markedly between models, with some models’ best and worst harnesses differing by over 10 percentage points and a same‑model compliance reviewer reducing violations from 9.6% to 6.4%. whyItMatters":"The findings suggest that validating a model’s compliance requires testing the specific model‑harness pair rather than the model alone, highlighting the importance of action logs over conversation transcripts for accurate conduct assessment."

FinRiskAtlas: Decision-Aligned Evaluation of Large Language Models for Financial Risk Review

FinRiskAtlas is a Chinese-language benchmark designed to evaluate large language models (LLMs) for financial risk review by focusing on decision‑aligned tasks rather than generic financial knowledge. It contains 9,742 instances across 53 task families, including 42 domain‑knowledge families and 11 downstream review operations defined by explicit evaluation contracts. The extended FinRisk‑Ask framework replays 680 pre‑action states from 104 professional trajectories, withholding future evidence during inference to assess evidence‑state control and request targeting. Results across 33 model configurations show that operation‑level evaluation yields distinct rankings and that knowledge‑based shortlisting can incur significant regret, while frequent use of the Ask branch does not necessarily improve evidence acquisition, highlighting gaps in broad financial capability scores.
