The Risk Premium Fallacy: Why Developing Economies Remain Undervalued
By Vera Songwe and Mahmoud Mohieldin
June 17, 2026
For decades, the narrative surrounding investment in the Global South has been stifled by a persistent, albeit flawed, mantra: the scarcity of "bankable" projects. Investors, development finance institutions, and credit rating agencies frequently point to a lack of viable opportunities in developing economies as the primary hurdle to scaling private capital. However, a growing body of evidence suggests that the real obstacle is not the quality of the projects themselves, but the prohibitive cost of capital driven by systemic biases in risk assessment.
When investors characterize a project as "unbankable," they are often masking a subjective—and frequently inaccurate—perception of risk. These inflated risk premia serve as a barrier to entry, effectively pricing developing nations out of global capital markets. As we navigate a global landscape defined by the urgent need for climate finance and infrastructure development, the persistence of these misaligned perceptions is not merely a technical error; it is a profound failure of the international financial architecture that continues to undermine global development.
The Evidence Gap: Challenging Market Assumptions
The disconnect between perceived risk and actual performance in emerging markets is no longer a matter of speculation. The recent release of the Global Emerging Markets (GEMs) Risk Database provides empirical weight to the argument that market actors are systematically overestimating the likelihood of default in developing economies.
For years, institutional investors have relied on conventional wisdom that equates emerging market assets with inherent instability. Yet, the data tells a different story. Default rates in these regions are frequently lower than the risk premia charged would imply, and recovery rates—the amount an investor recovers after a default—often exceed expectations. By ignoring these realities, the market creates a self-fulfilling prophecy: by charging excessive interest rates, investors make debt service unsustainable, thereby increasing the risk of the very defaults they fear.
A Chronology of Systemic Miscalculation
To understand how we arrived at this state of affairs, one must examine the evolution of risk assessment models and their failure to adapt to a changing global economic landscape.
- 1990s–2008: The Era of Homogenization: During the pre-financial crisis era, risk assessment was largely dominated by Western-centric models that treated developing economies as a monolithic block. Differences in governance, resource endowment, and macroeconomic management were often glossed over in favor of broad, country-tier risk ratings.
- 2008–2015: The Post-Crisis Retreat: Following the Global Financial Crisis, risk aversion among international banks skyrocketed. Capital flow to the developing world became increasingly selective, and the "flight to quality" phenomenon saw investors retreat to traditional, low-yield assets, starving the Global South of long-term investment.
- 2015–2020: The SDG Push: The adoption of the Sustainable Development Goals (SDGs) brought a renewed focus on private capital mobilization. However, the mechanism—blended finance—often failed to address the core issue of risk mispricing, instead relying on subsidies to offset the high cost of capital rather than addressing the risk models themselves.
- 2020–2024: The Pandemic and Inflationary Shock: The COVID-19 pandemic and subsequent inflationary pressures exacerbated the cost-of-capital gap. Developing nations were hit by a "double whammy": increased social spending requirements and a spike in borrowing costs due to central bank interest rate hikes in the Global North.
- 2025–2026: The Data Reckoning: We are currently in a phase where the transparency provided by initiatives like the GEMs Risk Database is forcing a confrontation with the facts. The data is increasingly difficult for credit rating agencies and institutional investors to ignore, setting the stage for a potential overhaul of how "emerging market risk" is calculated.
Supporting Data: Debunking the Myth of Volatility
The GEMs Risk Database offers a granular look at the performance of loans in developing economies. The data reveals several critical insights:
- Lower-than-Expected Default Rates: When comparing the actual default rates of infrastructure projects in developing economies against those in developed markets, the delta is often negligible. Yet, the risk premium attached to the former is frequently double or triple that of the latter.
- Higher Recovery Rates: Historically, the market has assumed that recovery in the event of default is arduous and unlikely in developing nations. Current data contradicts this, showing that legal frameworks and project structures in many emerging economies are more robust than commonly perceived.
- The Persistence of the "Country Risk" Bias: Investors continue to use sovereign credit ratings as a blunt instrument to price individual projects. This "sovereign ceiling" ignores the fact that many infrastructure projects are structured as ring-fenced, cash-flow-generating entities that are partially insulated from the broader macroeconomic environment of the host country.
Official Responses and the Institutional Stasis
Despite the overwhelming evidence, the response from the international financial community has been characterized by inertia. Credit rating agencies argue that their methodologies must account for "tail risks"—extreme, low-probability events—that could lead to sudden capital flight or currency collapse. While legitimate in theory, the consistent application of these fears across all sectors, including essential infrastructure, creates a bias that penalizes development.
Multilateral Development Banks (MDBs) have begun to acknowledge the need for reform. Discussions around the "Capital Adequacy Framework" (CAF) have centered on how MDBs can use their balance sheets more efficiently to crowd in private capital. However, without a fundamental change in how risk is priced by the private sector, these measures will only scratch the surface.
Government officials in the Global South have become increasingly vocal, arguing that the current system is not just inefficient, but discriminatory. The call for a new "Global Financial Compact" is gaining momentum, with leaders from Africa, Latin America, and Asia demanding more equitable representation in the institutions that define the global rules of the game.
Implications: The High Cost of Inaction
The implications of failing to correct these mispriced risks are profound and multifaceted.
1. The Climate Crisis Acceleration
The transition to a net-zero economy requires massive capital investment in the Global South. If projects remain "unbankable" due to inflated risk premiums, the energy transition will be delayed. This does not just affect the developing world; climate change is a global systemic risk, and a failure to decarbonize in one region impacts the entire planet.
2. Widening Inequality
The current capital allocation model ensures that the wealthy parts of the world enjoy access to low-cost capital, while the most vulnerable face the highest interest rates. This is a reversal of the logic of development finance, which should theoretically be the opposite. This disparity creates a "financing gap" that stunts growth, limits education, and prevents the development of robust healthcare systems.
3. The Debt Trap Cycle
When developing nations are forced to borrow at high rates to fund essential infrastructure, their debt-to-GDP ratios climb rapidly. This triggers a cycle where debt servicing consumes a larger portion of the national budget, leaving less for social investment, which in turn lowers credit ratings, increases the cost of borrowing further, and eventually leads to debt distress.
Conclusion: A Path Toward Reform
The "bankability" narrative is a facade that hides the structural flaws in our global financial system. To move forward, we must undertake a fundamental recalibration of how risk is perceived and priced. This requires:
- Transparency: Greater access to project-level data, such as that provided by the GEMs Risk Database, is essential. Information asymmetry is the investor’s enemy and the market’s poison.
- Methodological Innovation: Credit rating agencies and risk analysts must move away from blunt sovereign-level assessments toward project-specific risk modeling that accounts for local legal protections and cash-flow structures.
- Political Will: The international community must move beyond rhetorical support for development and address the regulatory frameworks—such as Basel III and Solvency II—that often inadvertently discourage institutional investors from holding assets in emerging markets.
Until these systemic biases are dismantled, the promise of global development will remain unfulfilled. It is time to treat the "risk premium" not as a law of nature, but as a market failure that requires urgent, data-driven correction. The evidence is on the table; the question is whether the global financial community has the courage to act upon it.
