Global financial markets have held steady this year, supported by strong AI investment and corporate earnings that offset Middle East conflict pressures and policy uncertainty. Yet financial stability risks remain elevated.
According to the IMF’s Global Financial Stability Report released this week, “Financial markets have remained resilient… but financial stability risks are elevated.” Weaker AI profitability, a sharp rise in sovereign yields or major cyberattacks could turn systemic if amplified by vulnerabilities.
For many African frontier economies the risks are sharper. “In emerging market economies, policy buffers have eroded in some cases, while the greater reliance of frontier economies on opaque alternative financing could weaken debt transparency and hinder future market access,” the report states.
Among weaker below-investment-grade emerging markets the median reserve adequacy ratio fell from 72% in the first quarter of 2026 to 63% in the second. Foreign-exchange interventions shifted toward Asia and Africa later in the year, but “economies that relied solely on foreign exchange interventions, including many in Asia and Africa, saw little meaningful recovery in exchange rates.”
Frontier spreads that widened about 60 basis points at the war’s onset have narrowed, yet funding costs stay elevated with U.S. Treasury yields above 4.5%. “Financing of the largest external debt buildups among frontier economies has been outside bond markets, particularly for lower-rated sovereigns,” the IMF notes.
“Continued buildup of these and other opaque transactions could increase the vulnerability of frontier economies to global shocks and hinder future market access,” it adds, calling transparent reporting “critical.”
South Africa shows low AI equity sensitivity, but energy-importing African countries face headwinds from the conflict.
Moody’s recently turned positive on sub-Saharan Africa’s outlook amid reforms and projected 4.3% growth, with Ghana and Zambia advancing restructurings. High debt-service burdens still constrain space. “Emerging and frontier market authorities should rebuild fiscal and external buffers, maintain a coherent policy mix, and strengthen disclosure of alternative financing arrangements,” the report recommends.
Global banks would stay broadly resilient under an adverse scenario, yet vulnerable institutions would emerge. For African frontier economies, compressed spreads, opaque debt and thinner buffers raise the chance that any global yield spike quickly raises funding costs and curbs market access.
