Emerging-market portfolio capital grew, but exit risk became more concentrated

What changed

The International Monetary Fund's April 2026 Global Financial Stability Report says cumulative nonresident portfolio flows into emerging markets approached USD 4 trillion in 2025. The important change is not only the amount. The nonbank financial institution share of these economies' portfolio debt liabilities doubled over two decades to about 80%.

Banks have not disappeared. BIS data show global cross-border bank credit grew 11% during 2025 to USD 38.1 trillion, while credit to emerging and developing economies increased 7%. But the holders of securities, providers of private loans and sources of marginal liquidity are increasingly varied. A market can no longer be assessed adequately through its aggregate inflow figure.

What the data actually says

The IMF estimates that portfolio debt liabilities average roughly 15% of GDP across emerging markets and exceed 20% in one-fifth of them. Portfolio equity liabilities average about 7% of GDP. Those figures measure exposure to market-based foreign capital; they do not predict that a crisis will occur.

Risk lies partly in owner behaviour. IMF analysis finds that hedge funds and investment funds respond more strongly to global risk shocks. Within the fund sector, passive mutual funds and exchange-traded funds show the greatest sensitivity. When portfolios track the same index, use similar volatility signals or face redemptions at the same time, selling can become synchronised even before a country's long-term fundamentals change.

Who is affected

HNW investors holding bonds, ETFs, emerging-market funds or private assets in recipient countries are directly exposed. Companies borrowing in foreign currencies are also affected because a change in investor demand can widen spreads and complicate refinancing. Investors in property or private businesses face indirect transmission through the exchange rate, cost of capital and domestic bank liquidity.

One category should not be folded into the same conclusion: Foreign direct investment. FDI generally involves control, operating assets and a longer holding period. Portfolio capital can trade more quickly, while private credit may lock capital contractually but leave recovery dependent on covenants and collateral. Each requires a different exit model.

Capital, timing and obligations

Before allocating, an investor can build an ownership map around five questions. First, how much of the asset is held by passive funds, leveraged funds and banks? Second, in what currency is it priced and settled? Third, does the asset maturity match the fund's redemption terms? Fourth, how concentrated is market-making capacity? Fifth, can domestic investors absorb foreign selling?

Currency needs a separate test. The BIS says the share of cross-border bank credit to emerging and developing economies denominated in currencies other than the major international currencies rose from 21% in 2019 to 29% in 2025. Currency diversification can reduce one dependency while adding new basis costs, hedging-liquidity constraints and legal exposures. A high local-currency yield can be erased by depreciation at exit.

Risks and unresolved questions

Private credit is a fast-growing segment with less complete data. The IMF reports that emerging-market private-credit transactions rose from about USD 14 billion in 2024 to more than USD 22 billion in 2025, with estimated assets under management of roughly USD 50–100 billion. The structure can supply capital where public markets are unsuitable, but infrequent marks do not mean that economic volatility has vanished.

On the policy side, foreign-exchange reserves, local-market depth, market-making arrangements and liquidity rules can soften a shock. BIS research stresses the need for resilient and adaptive frameworks. Global aggregates still cannot replace a country balance sheet, and the emerging-market label hides substantial differences among issuers.

What to watch next

Investors should monitor four measures together: Ownership by fund type; foreign-currency debt and refinancing needs; local-market trading depth; and redemptions or net selling during volatile periods. Return should be stress-tested by combining asset-price loss, market slippage and currency depreciation rather than changing only one variable.

One additional measure is the gap between advertised liquidity and executable liquidity. Average turnover in calm conditions does not show where a large position can exit when funds sell together. For a material allocation, investors should request order-book depth, issue size, ownership concentration and maturity schedules, then predefine a position-reduction threshold if those conditions deteriorate. This turns a general warning about flows into a portfolio rule that can be monitored before a stressed market removes the choice.

The near-USD 4 trillion stock reflects the appeal of emerging markets. But capital preservation during a difficult period is determined by more than how much money arrived. It depends on who owns the assets, how stable their funding is and whether enough buyers remain when many holders want to leave at once.
