Persistent insecurity and widespread financial exclusion in Makurdi town of Benue State have continued to exacerbate socio-economic vulnerabilities and drive criminal activities. This study therefore examines the effect of Savings and Credit Associations (SCAs) on crime reduction in Makurdi town. Employing a mixed-methods approach, data were gathered from 386 respondents using surveys and in-depth interviews across diverse wards in Makurdi. Quantitative analysis, supported by regression models, revealed that SCAs have a modest but statistically significant effect on reducing crime (R² = 0.053, p < 0.05), particularly by promoting financial stability and accountability among members. Qualitative insights illuminated the deeper social impacts of SCAs such as fostering mutual trust, reducing financial stress, and discouraging antisocial behaviors such as theft, burglary, and financial fraud. Community narratives affirmed that SCAs not only meet economic needs but also reinforce ethical standards, civic responsibility, and peaceful coexistence. The study concludes that SCAs are pillars of social resilience and informal security. It recommends that government, NGOs, and local leaders should invest in scaling and institutionalizing SCAs as viable instruments for financial inclusion and community-based crime prevention.
