Managing Economic Risks in Project and Financial Management: Interaction of National Security and Sustainable Development in a Globalized World

This study examines how project- and financial-level risk management influences national security and sustainable development during a global polycrisis. Integrating empirical data from the Allianz Risk Barometer, WEF Global Risks Report, ACFE Report to the Nations, and Ecological Threat Report, the research evaluates links between project failures, occupational fraud, and macroeconomic stability via systematic literature review and quantitative analysis. Findings show traditional models fail against systemic vulnerabilities, illustrated by a steel-copper price correlation surge from 0.22 to 0.55. Furthermore, occupational fraud consumes 5% of gross revenues, stressing the need for economic unshadowing and transparent procurement. Organizations must adopt nexus-based governance incorporating digital forensics, adaptive budgeting, and alignment with UN Sustainable Development Goals. Ultimately, mitigating micro-level economic risks is a vital prerequisite for national resilience.
