🎯 Problem Statement & Strategic Context
Business Challenge
Global Systemically Important Banks (G-SIBs) produce quarterly financial results accompanied by analyst Q&A transcripts and webcasts.
The Bank of England's Prudential Regulation Authority (PRA) supervises these institutions to uphold monetary and economic stability.
Core Problem: While quantitative metrics are readily incorporated by existing risk-assessment frameworks,
qualitative insights embedded in earnings-call discussions remain under-utilised.
Research Objective
By analysing multiple Global Systemically Important Banks and their quarterly earnings results over the period
2023-2025, identify key insights using advanced analytical techniques
that may be missed by traditional quantitative analysis methods.
Strategic Rationale & Methodology Justification
🔍
Beyond Traditional Metrics
Traditional financial analysis focuses primarily on numerical data from financial statements. Our approach incorporates
textual analysis of qualitative reports and transcripts, extracting insights from narrative
context surrounding the numbers that conventional methods often overlook.
🎯
Multi-Faceted Analysis Framework
By combining sentiment analysis, risk assessment, topic modelling, and financial metrics extraction,
we provide a holistic view of bank performance that increases the likelihood of identifying unique and valuable regulatory insights.
🦙
Domain-Specific AI Models
FinLLaMA's financial domain expertise surpasses general-purpose models in understanding
complex financial statements, regulatory language, and subtle sentiment shifts critical for G-SIB supervision.

Transcript Intelligence Mining
Earnings call transcripts contain forward-looking statements and management commentary
not found in static reports, revealing subtle strategic shifts and concerns essential for proactive regulatory oversight.
