AI-ENHANCED CREDIT SCORING USING ALTERNATIVE DATA FOR FINANCIAL INCLUSION IN PAKISTAN

Abstract

This study looks at how Artificial Intelligence can improve credit scoring for borrowers in Pakistan, especially those who struggle to get loans because they lack formal credit histories. Traditional lending still depends on collateral and old repayment records, which leaves out a large part of the population. With the rise of mobile banking and digital payments, new digital footprints such as telecom usage, mobile-wallet activity, and online transactions can now offer useful signals about a borrower’s behavior. The research tests whether AI can turn this data into fair and accurate credit decisions.

Using a dataset of 10,000 borrowers that reflects real microfinance clients in Islamabad, three models, Logistic Regression, Random Forest, and XGBoost were developed and compared. The models were trained on both traditional variables (income, loan history, debt ratio) and alternative data (telecom activity, wallet usage, digital purchase patterns). Their performance was checked through accuracy, calibration, and fairness metrics.

The results show that AI-based models clearly outperform the traditional approach. XGBoost achieved the highest accuracy (AUC 0.943), followed by Random Forest, while Logistic Regression showed the weakest performance. Adding alternative data improved prediction accuracy by nearly 18%, making it easier to identify reliable borrowers who would otherwise remain “credit invisible.” Fairness tests also showed that AI models, when properly tuned, reduced gender-based bias and produced more balanced decisions. SHAP analysis confirmed that income, credit history, telecom usage, mobile-wallet activity, and loan size were the strongest predictors of default.

The study concludes that AI-powered credit scoring can support financial inclusion in Pakistan by making lending decisions more accurate, transparent, and fair. It recommends that financial institutions adopt explainable AI tools, regulators strengthen data privacy frameworks, and pilot programs be used before full-scale deployment. While the study relies on simulated data, it provides a practical pathway for responsible AI adoption in Pakistan’s credit markets.
