Deep Learning for Credit Risk Prediction: A Survey of Methods, Applications, and Challenges
Credit risk prediction is central to financial stability and regulatory compliance, guiding lending decisions and portfolio risk management. While traditional approaches such as logistic regression and tree-based models have long been the industry standard, recent advances in deep learning (DL) have introduced architectures capable of capturing complex nonlinearities, temporal dynamics, and relational dependencies in borrower data. This study provides a comprehensive review of DL methods applied to credit risk prediction, covering multi-layer perceptron, recurrent and convolutional neural networks, transformer, and graph neural networks. We examine benchmark and large-scale datasets, highlight peer-reviewed applications across corporate, consumer, and peer-to-peer lending, and evaluate the benefits of DL relative to classical machine learning. In addition, we critically assess key challenges and identify emerging opportunities. By synthesising methods, applications, and open challenges, this paper offers a roadmap for advancing trustworthy deep learning in credit risk modelling and bridging the gap between academic research and industry deployment.
"Across the peer-reviewed evidence, deep models tend to outperform traditional scorecard and ensemble methods when trained on sufficiently large, temporally representative datasets with rich behavioural and relational information. However, the literature also reveals gaps that constrain reliable real-world adoption."
Executive Impact & Strategic Advantage
Deep learning offers a pathway to significantly enhance credit risk prediction, moving beyond static models to capture dynamic, relational, and highly complex borrower behaviors. This translates directly into more accurate lending decisions, reduced losses, and improved regulatory compliance, driving a competitive edge in financial markets.

Our Recommendation: To fully leverage Deep Learning for credit risk, financial institutions should adopt interpretable-by-design architectures, implement robust evaluation frameworks with time-ordered validation and calibration-aware reporting, and integrate privacy-preserving collaborative learning. Prioritizing deployment-aligned governance and ethical AI principles is crucial for building trustworthy, regulation-ready models that extend beyond predictive accuracy to ensure lifecycle reliability and auditability.

Deep learning for tabular borrower data has evolved from simple multilayer perceptrons (MLPs) to specialised architectures that leverage regularisation, attention, embeddings, and hybrid ensembling. This subsection reviews representative studies that apply deep tabular models to corporate, retail, and institutional lending data, highlighting methodological contributions, empirical findings, and comparative performance relative to conventional ML models.
Sequential deep learning approaches model the evolution of borrower or portfolio behaviour over time, offering substantial advantages over static classifiers that ignore risk trajectories. These models capture temporal patterns linked to repayment behaviour, behavioural drifts, cyclical spending, macroeconomic shocks, and post-origination delinquency paths.
Transformers represent a major departure from recurrent architectures by replacing sequential recurrence with self-attention, enabling parallel computation and global dependency modelling across features, time steps, or modalities. This property is attractive in credit modelling, where behavioural variables, categorical features, and text-based signals interact in complex, non-local patterns.
Graph neural networks (GNNs) have gained significant traction for credit risk prediction due to their ability to encode relational dependencies that conventional tabular and sequential models ignore. Borrowers interact within rich financial ecosystems involving co-application, ownership links, shared directorship, supplier-customer contracts, and transaction flows, making relational learning a natural extension to deep credit scoring.

Case Study: Web-Scale GNN for Supply-Chain Credit Risk
A large-scale industrial GNN pipeline successfully processed 23.4 million nodes for supply-chain mining and 8.6 million nodes for default prediction. This model achieved an impressive AUC of 0.995 for supply-chain tie mining and 0.701 for loan-default prediction, significantly outperforming static graph-learning competitors. It demonstrated GNNs' capability to operate at web-scale for national credit infrastructure, highlighting their strength in capturing complex relational dependencies beyond what traditional models can achieve.
