IIF: $26.3bn EM Outflows in September — Rollover Pressure Shifts to Dollar Bonds and Long-Dated Eurobonds

Foreign investors withdrew roughly $26.3 billion from emerging-market stocks and bonds in September, a reversal driven in the bundle by a hawkish US policy backdrop. The concrete change is a reduction in external demand for EM fixed income and equities that raises the refinancing premium for dollar issuance and shrinks the pool of marginal buyers for new supply.

The transmission to African credit is direct: tighter external demand lifts spread premia on dollar-denominated sovereign and corporate paper, with long-duration maturities most exposed through higher discount rates and duration losses. Countries with large upcoming external amortisation — for example Ghana and Zambia in the high-beta sovereign cohort, and corporates in commodity-linked sectors — face higher rollover risk as the effective cost of new external issuance increases and secondary liquidity thins.

A stronger US rate backdrop also elevates refinancing premia on the belly and long end of curves for marginal credits, while shorter-term local bills in better-funded borrowers (South Africa’s short curve, Morocco’s bill market) should be less affected by duration pull-to-par but still see demand repricing. Compared with regional peers, oil exporters (Angola, to a lesser extent Nigeria given its fuel-import mix) retain structural cushions through commodity receipts, so their external curves may widen less than cocoa- and copper-linked credits (Ghana, Ivory Coast, Zambia) whose FX earnings are more volatile.

The IIF flow reversal therefore concentrates vulnerability in dollar-heavy, long-dated liabilities and in high-beta commodity exporters with near-term rollovers. We watch two conditional indicators: changes in primary-market concession spreads for African Eurobond taps and near-term issuance volumes, and shifts in non-resident holdings of local-currency sovereign bills, which will signal whether the outflow has transient mark-to-market effects or is pressuring actual funding channels.
