The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The central object is the nine-task question set with a weighted composite score. Tasks 1–5 (abbreviation, definition, NER, QA, and link retrieval) each count 10%; Task 6 (CFA and CPA certificate questions) counts 20%; and Tasks 7–9 (CDM, MOF licenses, and XBRL analytics) each count 10%. Answers are scored by accuracy for exact-answer tasks, F1 for NER, BERTScore for definition recognition, and FActScore for open-ended QA, producing the final score that drives the ranking.
What would settle it
A reader could take the six submitted systems and the three baselines, re-score them on a fresh, independently verified set of CFA/CPA, regulation, CDM, MOF, and XBRL questions using equal one-ninth weights for all nine tasks, and compare against a human expert answer key. If the top system changes or expert agreement with the reference labels is weak, the published ranking is an artifact of protocol choices rather than a measure of regulation expertise.
Extended reading notes
Core claim
On the paper's own terms, the central discovery is a new benchmark plus a first measurement of where LLMs stand on financial regulation. The nine tasks cover information retrieval, certificate exams, the Common Domain Model, the Model Openness Framework, and XBRL analytics, with scores combined as 10% for each of Tasks 1–5, 20% for the certificate task, and 10% for each of Tasks 7–9. FinMind-Y-Me tops the submitted teams with 0.54801 by fine-tuning Qwen 2.5-7B-Instruct with sequential and reasoning-based training, yet both GPT-4o and Mistral Large 2 finish ahead. The consistent cross-model failures on abbreviations and link retrieval, and the zero NER scores of three submitted models, are presented as evidence of specific capability gaps rather than general uselessness.
Load-bearing premise
The ranking rests on the assumption that the hand-written reference answers are correct and unambiguous, the 10%/20%/10% task weights and random question subsets do not favor one model over another, and the models never memorized the test questions during pretraining.
Editorial extensions
If this is right
- If the benchmark is accepted, LLMs are currently usable as regulatory Q&A assistants, since all systems scored above 0.6 on QA-style subtasks such as CDM and XBRL term explanation.
- Abbreviation recognition is a reliable weakness, with no system exceeding 0.38 on the abbreviation task, so financial-domain tools need explicit ticker and acronym handling.
- Link retrieval near zero for most submitted models shows that current fine-tuning alone does not teach models to locate regulatory documents, making retrieval augmentation the natural next step.
- The certificate-task results suggest that reasoning-enhanced fine-tuning, as in FinMind-Y-Me, is a promising path toward professional exam performance.
- Domain fine-tuning can trade away capabilities, since Uniandes beat its base Llama 3.1-8B on XBRL terms but fell below it on financial math and tag queries.
Reading between the lines
- Editorial inference: the 10%/20%/10% weight scheme is not defended against alternatives, and with abbreviation recognition sampled from thousands of stock tickers, a single hard subtask may drag scores down disproportionately.
- Editorial inference: the poor link-retrieval results may partly reflect an exact-match scoring rule, so a model that returns the correct document in a different URL form gets no credit and the capability gap may be smaller or larger than the table shows.
- Editorial inference: because certificate questions are private and withheld, the benchmark can be reused over time to detect pretraining contamination, since future models that improve on those questions without being trained on them would point to reasoning rather than memorization.
- Editorial inference: merging the question sets into a public leaderboard would let the community test whether the reported weaknesses persist across newer model generations.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper reports on the Regulations Challenge, a shared task at COLING 2025 FinNLP-FNP-LLMFinLegal, in which the authors created nine tasks and corresponding question sets to evaluate LLMs on financial regulation understanding. The tasks cover abbreviation and definition recognition, NER, QA, link retrieval, CFA/CPA certificate-style questions, CDM, MOF licensing, and XBRL analytics. Six teams submitted full solutions; the paper describes their methods, reports per-task scores, and gives a final ranking obtained as a weighted average with 10% weight on Tasks 1–5 and 7–9 and 20% on Task 6. The top submitted system, FinMind-Y-Me, achieves 0.54801, below the GPT-4o baseline at 0.63567 and the Mistral Large 2 baseline at 0.62489. The paper claims that these nine tasks provide a meaningful evaluation of FinLLM professional capability in financial regulations, and it identifies strong QA performance and weak abbreviation and link-retrieval performance as notable findings.
Significance. If the measurement claims are valid, the paper provides one of the first structured, multi-area evaluations of LLMs on financial regulation compliance, with a useful decomposition across information retrieval, certificate-style reasoning, machine-readable standards (CDM, XBRL), and open-model licensing. The transparent disclosure of dataset sizes, metrics, sampling decisions, and the private status of the certificate set is a strength, as is the inclusion of three baselines and the later integration of results into the Open FinLLM Leaderboard. The main contribution is organizational and empirical rather than methodological: it produces a benchmark and a leaderboard that could be reused by future shared tasks. The reliability of the leaderboard, however, rests on question-set quality and answer-key correctness, which the paper does not currently demonstrate. Because several reported rank gaps are small, the absence of uncertainty quantification and the unvalidated private certificate task are material threats to the paper's central claim.
major comments (4)
- [2.2 and Table 3] The certificate task (Task 6) is the least supported link in the evaluation chain. Section 2.2 states that the set contains 346 questions from CFA real/mock exams and CPA REG mock exams, is stored privately, and will not be released; however, it gives no description of how the authors verified the answer key against official exam keys, how ambiguous or disputed questions were resolved, or how the set was sampled. Task 6 carries 20% of the final score (Section 4.1), double the weight of each other task. Table 3 shows large cross-model spreads, e.g., REG CPA scores range from 0.2376 (finma) to 0.7129 (GPT-4o); any systematic error in the private answer key would therefore directly move the final ranking, including the margin between the top submitted system (0.54801) and the second-place system (0.43929). The authors should either provide an independent validation procedure for the answer key, report error-analysis statistics on disputed questions, or include a sensitivity analysis that re-ranks participants with Task 6 removed or reweighted.
- [4.1 and Tables 3–4] The sampling and exclusion decisions in Section 4.1 are not accompanied by uncertainty estimates. The authors randomly sampled 200 of 3,298 stock-ticker questions and 90 of 1,000 financial-math questions, and they excluded the 50 financial-ratio-formula questions entirely. No confidence intervals, bootstrap estimates, or significance tests are reported for any score in Tables 3–4. This is consequential because several ranking differences are small: Uniandes (0.43929) and GGBond (0.43798) differ by 0.00131 in final score, and FinMind-Y-Me's lead over Uniandes is about 0.109, which is comparable to the 10% weight of a single task. The authors should report standard errors or bootstrap intervals for the final scores and for the affected subtask scores, and should state whether the ranking is stable across alternative random subsets.
- [4.1] The hand-chosen weighting scheme is presented without justification or robustness analysis. Section 4.1 assigns 10% to each of Tasks 1–5, 20% to Task 6, and 10% to each of Tasks 7–9, but the paper does not explain why Task 6 deserves twice the weight of the others, nor does it test alternative weights. Given the small margins in the reported ranking, the top position among submitted teams could plausibly change under a different defensible weighting. The authors should provide a sensitivity analysis over reasonable weight vectors, or explicitly frame the ranking as contingent on this particular weighting and report the rank robustness.
- [2.3–2.5 and Table 2] For the generated question sets (CDM, MOF, XBRL), the evaluation depends on gold or reference answers via FActScore and BERTScore, but the paper does not describe any human validation, inter-annotator agreement, or correction protocol for these answers. Section 2.3 indicates that 80 CDM QA pairs were generated from documentation and 46 were collected from FAQs and experts, while Section 2.5 relies on the XBRL Agent dataset; nowhere is there a statement that an independent annotator checked the reference answers for correctness. If the reference answers were produced by an LLM and used without verification, the reported scores may measure agreement with the generator rather than factual correctness. The authors should report the curation and validation procedure, including the number of human annotators and the agreement rate, or provide a sample of verified reference answers.
minor comments (6)
- [4.3] In the discussion of certificate-task performance, the paper writes 'IntelliChain Starts'; this should be 'IntelliChain Stars' to match the team name used elsewhere.
- [References] The reference for Chantangphol et al. contains 'based on thalle', which appears to be a typo; the intended model name should be spelled out correctly.
- [Table 3 caption] The caption says 'The rankings of teams and evaluation results', but the table also lists baselines; the caption should state that baselines are included for comparison and are not ranked teams.
- [5] The conclusion states that question sets will be merged into the Open FinLLM Leaderboard, but Section 2.2 says the certificate set will not be released; the paper should clarify exactly which subsets will be released and under what license.
- [References] The reference for 'Audit-FT (Huang et al.)' lacks a year and full bibliographic details, and several workshop papers in the proceedings are cited without page numbers or publication years.
- [References] The Mistral AI reference is listed as 'Large enough' and is not informative; it should cite the model card or technical report with a version number and access date.
Circularity Check
No circularity: the reported leaderboard scores are measured outputs on constructed question sets, not quantities derived from the inputs that define them; self-citations supply data sources but are not load-bearing.
full rationale
This paper is a shared-task benchmark report rather than a derivation, so there is no target quantity being predicted from fitted inputs. The nine tasks and question sets are assembled from official regulatory sources, external exam materials (CFA, CPA REG), CDM documentation, the MOF paper, and the authors' prior XBRL Agent dataset; the reported rankings are weighted averages of measured accuracy, F1, BertScore, and FActScore on those sets. No score is defined in terms of a claim it is supposed to predict, and no parameter is fitted and then renamed as a result. Self-citations to XBRL Agent, MOF, and the Open FinLLM Leaderboard provide data or framing, but the central ranking claims rest on observable model outputs rather than on those citations being true. The privately held and unreleased certificate question set is a transparency and validation limitation, not a circular step, because the certificate scores are externally sourced exam questions measured against an answer key rather than a quantity defined by this paper. Therefore no circularity is found.

Financial large language models (FinLLMs) have been applied to various tasks in business, finance, accounting, and auditing. Complex financial regulations and standards are critical to financial services, which LLMs must comply with. However, FinLLMs' performance in understanding and interpreting financial regulations has rarely been studied. Therefore, we organize the Regulations Challenge, a shared task at COLING 2025. It encourages the academic community to explore the strengths and limitations of popular LLMs. We create 9 novel tasks and corresponding question sets. In this paper, we provide an overview of these tasks and summarize participants' approaches and results. We aim to raise awareness of FinLLMs' professional capability in financial regulations.
