This study investigated the effect of blockchain management strategies on organisational competitiveness of selected banks in Delta State. Specifically, the study sought to determine the effect of blockchain governance and regulatory compliance, evaluate the effect of strategic integration of blockchain systems. A survey research design was employed, and data were collected from employees of selected commercial banks. Out of 109 copies of questionnaire distributed, 100 valid responses were analyzed using descriptive statistics, correlation analysis, and multiple regressions to examine both direct and indirect effects of blockchain management strategies on organisational competitiveness. The findings revealed that all four blockchain management strategies significantly and positively influence organisational competitiveness. Specifically, blockchain governance and regulatory compliance (β = 0.326, p < 0.001), strategic integration of blockchain systems (β = 0.276, p < 0.001), each contribute to improved operational efficiency, innovation, and market positioning. Based on these findings, the study concludes that blockchain management strategies are key drivers of competitive advantage in the banking sector, and banks should strengthen governance frameworks, integrate blockchain into core operations, invest in security and risk mitigation, and develop technical expertise among staff. The study recommends that policymakers provide clear regulatory guidelines and capacity-building initiatives to support secure and effective blockchain adoption.
