The persistent shortfall of financing for essential infrastructure across emerging markets and developing economies (EMDEs) remains one of the most significant hurdles to global economic stability and the successful execution of the international energy transition. While these regions possess the greatest need for modernized transport, energy, and digital networks, they are simultaneously the most constrained by international banking regulations that were originally designed to safeguard the global financial system from systemic collapse. Specifically, the Basel III framework, as currently interpreted and implemented by national regulators, has unintentionally created a regulatory environment that discourages commercial bank participation in EMDE project financing. By failing to fully recognize the efficacy of credit enhancement tools and by applying overly conservative risk-weighting to long-term infrastructure assets, these rules have driven the cost of capital to levels that stifle otherwise viable and bankable projects.
The Disconnect Between Regulatory Theory and Infrastructure Reality
Project finance is a specialized lending structure used primarily for long-term infrastructure and industrial projects. Unlike traditional corporate lending, which relies on the overall balance sheet of a company, project finance depends on the cash flows generated by the project itself for repayment. Despite its catalytic role in driving economic growth, the current regulatory landscape treats this asset class with extreme caution. Under both the Standardised Approach (SA) and the Internal Ratings-Based (IRB) approach of the Basel III framework, project finance is subject to high capital charges.
This conservatism persists despite a growing body of empirical evidence suggesting that project finance is inherently more resilient than other forms of lending. Data from the Global Infrastructure Hub and major credit rating agencies consistently show that infrastructure project defaults are relatively low, particularly after the initial construction phase is completed. Furthermore, the recovery rates for these projects—the amount of debt recovered after a default—are significantly higher than those for standard corporate loans. However, the Basel III framework does not adequately differentiate between the high-risk construction phase and the lower-risk operational phase of a project, forcing banks to maintain high capital buffers throughout the entire lifecycle of the loan. This lack of nuance makes it prohibitively expensive for global banks to hold these assets on their balance sheets, leading to a "flight to quality" toward advanced economies and leaving the Global South underserved.
The Growing Infrastructure Gap and the Energy Transition
The urgency of this issue is underscored by the current state of global climate goals. According to recent projections from the International Energy Agency (IEA), global clean energy investment is expected to reach US$2 trillion this year. However, a disproportionate amount of this capital is flowing into advanced economies and China. The infrastructure and energy transition finance gap in the Global South remains as wide as ever, threatening to leave entire regions behind in the shift toward a low-carbon economy.
The binding constraint is not a lack of global liquidity. Institutional investors and commercial banks have trillions of dollars at their disposal. Instead, the bottleneck is the structural cost of capital in EMDEs, which remains significantly higher than in advanced markets. When a bank assesses a project in a developing nation, it must account for "country risk ceilings." These ceilings often overstate the actual risk of a specific project by tethering its credit rating to the sovereign rating of the host country. Even if a project is backed by robust collateral, has a reliable revenue stream in a stable currency, and is co-financed by a Multilateral Development Bank (MDB), the regulatory "overlay" can blunt these advantages, driving up the interest rates charged to borrowers.
A Chronology of Banking Regulation and Its Impact on the Global South
To understand the current impasse, one must look at the evolution of the Basel Accords. The Basel Committee on Banking Supervision (BCBS) introduced Basel I in 1988 to establish minimum capital requirements for banks. Following the 2008 financial crisis, the committee developed Basel III to address the vulnerabilities exposed by the collapse of the subprime mortgage market. The primary goal of Basel III was to increase the quantity and quality of capital held by banks, ensuring they could weather significant economic shocks.
While these regulations successfully bolstered the stability of the Western banking system, their application to project finance in developing nations was largely a secondary consideration. Between 2010 and 2017, as the various components of Basel III were finalized, emerging market representatives frequently raised concerns that the "one-size-fits-all" approach to risk-weighting would penalize developing economies. By 2023, as the final implementation phase—often referred to as "Basel IV" due to its complexity—began to take effect, the impact on EMDE infrastructure became undeniable. The cost of borrowing for an energy project in Sub-Saharan Africa or Southeast Asia can be three to four times higher than a similar project in Europe, largely due to the regulatory capital that banks must set aside.
Technical Adjustments and the Path to Reform
The International Chamber of Commerce (ICC) and various global financial stakeholders have proposed a practical agenda for reform that seeks to balance financial stability with the need for development. This agenda is divided into two distinct phases: technical adjustments and structural reforms.
Phase One: Technical Clarifications
Small, targeted adjustments to the implementation of Basel III could unlock substantial volumes of private investment without requiring a complete rewrite of the rules. These adjustments could be issued as "Frequently Asked Questions" (FAQs) or guidance notes by the Basel Committee. Key technical priorities include:
- Enhanced Recognition of Credit Mitigation: Regulators should provide clearer guidance on how banks can use guarantees from MDBs and export credit agencies to reduce their capital requirements. Currently, the recognition of these "credit-risk-mitigation" tools is inconsistent across jurisdictions.
- Granular Risk Weighting: Instead of a flat risk weight for all project finance, the framework should allow for a reduction in capital charges once a project reaches the operational phase and demonstrates stable cash flows.
- MDB Participation Benefits: There is a strong case for formalizing the "Preferred Creditor Status" of MDBs within the Basel framework. When a commercial bank co-finances a project with an institution like the World Bank or the African Development Bank, the risk of default is statistically lower, and this should be reflected in the bank’s capital calculations.
Phase Two: Structural Reforms
Beyond technical fixes, the ICC recommends that the Basel Committee be mandated to establish new work programs focused on the long-term sustainability of EMDE finance. This would involve:
- Revisiting Country Risk Overlays: A fundamental re-evaluation of how sovereign risk affects private project ratings is necessary. If a project is ring-fenced and has offshore revenue accounts, it should not be strictly limited by the host country’s credit ceiling.
- Data-Driven Calibration: The committee should utilize the Global Emerging Markets (GEMs) Risk Database—a massive repository of default data shared by MDBs—to calibrate risk weights more accurately. This data proves that EMDE infrastructure defaults are far less common than current Basel models assume.
Stakeholder Reactions and Economic Implications
The call for reform has garnered support from a diverse coalition of international actors. Multilateral Development Banks have been vocal about the need for "regulatory breathing room" to allow private capital to flow alongside public funds. "We cannot close the infrastructure gap with public money alone," noted a senior official from a major development bank during a recent summit. "If the regulatory environment makes it unprofitable for commercial banks to join us, the energy transition in the Global South will fail."
From the perspective of commercial lenders, the current rules create a "capital trap." Banks are often eager to participate in high-impact ESG (Environmental, Social, and Governance) projects to meet their own sustainability targets, but the "output floor" mandated by Basel III—which limits the benefit banks can get from their internal risk models—forces them to use the more conservative Standardised Approach. This effectively penalizes banks for having sophisticated risk-management systems that might otherwise justify lower capital holdings for safe infrastructure assets.
Broader Impact: Stability Through Growth
It is essential to clarify that these proposed reforms are not intended to weaken prudential safeguards. On the contrary, by aligning capital requirements with real-world risk, the global financial system becomes more efficient. When capital is misallocated due to overly broad regulations, it creates its own form of systemic risk—the risk of economic stagnation and social instability in the Global South.
If the Basel Committee and national regulators adopt these clarifications, the implications for the Global South would be transformative. Lowering the cost of capital by even a few percentage points could make hundreds of pending renewable energy, water treatment, and transportation projects financially viable. This would not only accelerate the transition to a green economy but also foster regional stability through job creation and improved public services.
The challenge ahead lies in the coordination between regulators. While the Basel Committee sets the international standards, it is up to national authorities in the US, the EU, and elsewhere to implement them. A harmonized approach that recognizes the unique profile of EMDE project finance is the only way to ensure that the "catalytic role" of infrastructure in driving economic growth is not stifled by the very rules meant to protect the world’s wealth. The path forward requires a shift from a purely defensive regulatory posture to one that actively enables the sustainable development of the global economy.
