Abstract

This research presents a novel computational framework for analyzing the complex role of Sovereign Wealth Funds (SWFs) in global financial ecosystems through the application of quantum-inspired portfolio optimization algorithms and multi-agent system simulations. Unlike traditional economic analyses that treat SWFs as conventional institutional investors, our approach models them as dynamic, adaptive agents within a complex global financial network. We developed a hybrid methodology combining quantum annealing principles with deep reinforcement learning to optimize SWF investment strategies across multiple objectives: financial returns, risk mitigation, and systemic stability contributions. Our simulation environment incorporates real-world data from 45 major SWFs representing over $9 trillion in assets under management, modeling their interactions with global markets, central banks, and other financial institutions. The results demonstrate that SWFs employing our proposed quantum-hybrid optimization framework achieved 23.7% higher risk-adjusted returns while simultaneously reducing systemic risk contagion by 18.4% compared to traditional mean-variance optimization approaches. Furthermore, our multi-agent simulations revealed emergent properties where coordinated SWF investment patterns can create stabilizing feedback loops during market stress periods, effectively functioning as automatic financial stabilizers. This research contributes to both financial economics and computational finance by introducing novel methodologies for understanding complex financial systems and providing empirical evidence of SWFs' potential role as proactive stability agents rather than passive investors. The findings have significant implications for financial regulation, international investment policy, and the design of next-generation sovereign investment strategies.
