The International Monetary Fund has warned that emerging markets are increasingly reliant on portfolio flows from hedge funds and institutional investors, exposing them to sharp capital outflows during periods of stress. Recent market turbulence following the Iran war has already triggered the largest outflows since the pandemic, highlighting growing vulnerabilities.
Portfolio Flows Now Dominate EM Financing
According to the IMF’s latest Global Financial Stability Report, emerging markets now receive the majority of their external financing from portfolio investors such as hedge funds, pension funds and insurance companies.
The share of foreign debt financing coming from these investors has doubled over the past two decades to around 80%, as banks scaled back lending after the 2008 global financial crisis.
Since then, emerging markets have attracted nearly $4 trillion in cumulative inflows.
Benefits Come With Heightened Risks
The IMF acknowledged that strong portfolio inflows have helped emerging markets access cheaper and longer-term financing during periods of abundant global liquidity.
However, the Fund cautioned that these investors have become increasingly sensitive to risk and more prone to rapid withdrawals when global financial conditions deteriorate.
Countries and companies relying heavily on such flows are now “particularly vulnerable to global financial shocks,” the report said.
Risk of Sudden Stops and Currency Pressure
The IMF warned that a sudden reversal in portfolio flows could trigger:
- Increased external financing pressures
- Widening corporate and sovereign bond spreads
- Sharp currency depreciations
The risks are amplified in countries with shallow financial markets and limited policy flexibility.
Hedge funds and other investment funds were identified as especially reactive to changing risk conditions.
Rising Exposure Across Debt and Equity Markets
External portfolio debt liabilities in emerging markets now average about 15% of GDP, according to the IMF.
Portfolio equity liabilities stand at roughly 7% of GDP, but represent a significant share of market capitalization in some countries.
In certain cases, large foreign participation has driven strong currency performance, such as Hungary’s forint, which gained about 20% against the US dollar last year before reversing course.
Iran War Triggers Sharp Reversal in Flows
The outbreak of the Iran war has led to a sharp reversal in capital flows.
Data from the Institute of International Finance (IIF) showed that foreign investors pulled $70.3 billion from emerging market assets in March — the largest outflow since the Covid-19 market shock in 2020.
Equity markets bore the brunt, with $56 billion in outflows — the biggest decline in at least two decades.
Asia at the Center of the Sell-Off
Emerging Asia accounted for most of the equity outflows, reflecting the region’s vulnerability to higher oil prices and repositioning in technology stocks.
The war, which pushed oil prices above $100 per barrel, significantly weakened investor risk appetite.
Markets that had performed strongly earlier in the year quickly reversed course. For instance, South Korean equities surrendered a large portion of their earlier gains following the onset of the conflict.
Not Yet a Systemic Crisis — But Risks Rising
The IIF noted that March’s outflows do not yet represent a full-scale systemic event across all emerging markets.
Instead, the episode reflects a “concentrated risk-off” shift, with equity markets acting as the primary adjustment channel.
Debt flows, while negative at $14.2 billion, were more contained, and some regions — including China and parts of Latin America — continued to see inflows.
However, analysts warned that if the conflict persists, the pressure on emerging markets could intensify.
“Pain Could Deepen” if Conditions Worsen
Economists highlighted several factors that could prolong instability:
- Persistently high inflation
- Delayed easing of global financial conditions
- A stronger US dollar
- Limited policy flexibility in vulnerable economies
Under such conditions, stabilizing capital flows may become significantly more difficult.
New Channels: Private Credit and Crypto Flows
The IMF also pointed to the rapid growth of cross-border private credit and stablecoin flows into emerging markets.
These flows, often linked to developments in cryptocurrency markets, introduce additional layers of volatility and risk.
IMF Policy Recommendations
To mitigate vulnerabilities, the IMF urged emerging market economies to:
- Strengthen institutional frameworks
- Build foreign exchange reserve buffers
- Maintain sustainable levels of public debt
Conclusion
The IMF’s findings highlight a structural shift in how emerging markets are financed — one that brings both opportunity and increased fragility.
While portfolio inflows have supported growth, the risk of sudden reversals has become a defining challenge.
The recent wave of outflows following the Iran war underscores how quickly sentiment can shift — and how exposed emerging markets remain to global shocks.
