Data and AI in Finance

Financial institutions rely on large volumes of transactional, behavioral, market, and alternative data to support investment analysis, credit assessment, marketing, compliance monitoring, and risk forecasting. Data is now considered a strategic asset class.

AI technologies are used for algorithmic trading, customer onboarding (eKYC), credit scoring, robo-advisory, fraud detection, anti-money laundering (AML), sentiment analysis, and chatbots. Machine learning models can uncover patterns and anomalies that traditional systems cannot.

The EU AI Act introduces a risk-based classification of AI systems, including specific rules for high-risk applications such as credit scoring, biometric identification, and trading algorithms. It mandates transparency, human oversight, accuracy, and robustness.

Financial firms must ensure data quality, integrity, lineage, and protection. Data governance frameworks address metadata management, classification, retention policies, and ethical sourcing—aligned with compliance under GDPR, PSD2, and DORA.

The General Data Protection Regulation (GDPR) governs the processing of personal data. AI systems must ensure lawfulness, purpose limitation, data minimization, and transparency—especially when profiling individuals or making automated decisions.

Financial regulators increasingly demand that AI models be explainable, auditable, and fair. Black-box models pose challenges for risk management and consumer rights. Institutions must document model assumptions, limitations, and validation processes.

AI models must be tested for bias and discrimination, especially in lending, hiring, and insurance underwriting. Ethical AI frameworks guide institutions to ensure inclusiveness, non-discrimination, and accountability in automated decision-making.

Regulatory technology (RegTech) solutions use AI to automate regulatory reporting, monitor conduct risk, detect suspicious transactions, and manage legal obligations. These tools enhance compliance efficiency and reduce operational costs.

Quantitative strategies now use alternative data (e.g., satellite images, social media feeds, web scraping) alongside traditional financial metrics. AI-driven models support real-time trading, sentiment extraction, and portfolio optimization.

AI enhances customer segmentation, identity verification, and behavioral profiling through data clustering and predictive models. This improves user experience and supports compliance with AML, CFT, and suitability rules.

Financial institutions must assess the accuracy, robustness, and stability of AI models through rigorous validation, monitoring, and backtesting. Model risk is subject to internal governance and supervisory scrutiny (e.g., ECB expectations).

Modern AI applications require scalable cloud infrastructure and data platforms for real-time processing. Institutions must evaluate vendor risks, data localization, encryption, and interoperability when using public or hybrid clouds.

AI systems must be resilient to adversarial attacks, data poisoning, and model inversion. Financial firms must implement cybersecurity safeguards and comply with DORA and NIS2 obligations for data and system integrity.

In Slovenia, financial data use and AI applications must comply with GDPR, AI Act (once enacted), and sectoral laws. The Bank of Slovenia, ATVP, and the Information Commissioner provide oversight on data ethics and technological innovation.

The convergence of AI, big data, and quantum computing will redefine financial services. Institutions must develop digital ethics strategies, talent pipelines, and governance models to stay competitive while managing reputational and compliance risks.
