This paper investigates the multifaceted impact of trade uncertainty and geopolitical fragmentation on the stability of the South African financial system. As global trade dynamics shift due to elevated tariffs, fractured alliances, and the weaponisation of financial infrastructure, South Africa, an open, trade-dependent economy, faces heightened vulnerabilities across macroeconomic and financial channel.

Trade uncertainty manifests through exchange rate volatility, capital outflows, and deteriorating investor sentiment, which strain financial institutions, particularly those with foreign currency liabilities or exposure to export-oriented sectors. Empirical analysis using a structural VAR model confirms that even moderate shocks to trade policy uncertainty can tighten financial conditions and dampen economic activity. These effects, while modest in isolation, may compound existing vulnerabilities in a context of constrained fiscal space, high unemployment, and external financing needs.

Geopolitical fragmentation further complicates the financial stability landscape by disrupting cross-border capital flows, fragmenting payment systems, and intensifying operational risks. The proliferation of alternative financial architectures, such as China’s CIPS and Russia’s SPFS, alongside rising cyber threats and the accelerated adoption of artificial intelligence, introduces new challenges for regulatory oversight and institutional resilience. South African financial institutions must navigate increased compliance burdens, valuation risks, and cybersecurity threats in a fragmented global environment. The paper concludes that safeguarding financial stability amid these disruptions requires a multi-pronged policy response, including trade diversification, enhanced macroprudential frameworks, and improved cross-border regulatory coordination. Strengthening institutional capacity and regional cooperation will be critical to navigating this increasingly multipolar and uncertain global order.
