The persistent shortfall of finance for essential infrastructure in emerging markets and developing economies (EMDEs) remains one of the most significant hurdles to global economic stability and the achievement of international climate goals. Despite the International Energy Agency (IEA) projecting a record US$2 trillion in global clean energy investment for the current year, the distribution of this capital remains starkly uneven, with the Global South facing a widening gap in funding for both traditional infrastructure and the energy transition. The core issue is not a global scarcity of liquidity, but a systemic misalignment between perceived risk and regulatory requirements, primarily driven by the current interpretation and implementation of the Basel III framework. While these regulations were designed to bolster the resilience of the global banking system following the 2008 financial crisis, their unintended consequences are now stifling the flow of private capital into the regions that need it most.
The Structural Reality of the EMDE Finance Gap
The infrastructure gap in EMDEs is estimated to reach trillions of dollars over the next decade. According to data from the Global Infrastructure Hub, the world faces a $15 trillion gap in infrastructure investment by 2040, with a disproportionate share of that deficit located in developing nations. In these regions, infrastructure serves as a primary catalyst for economic growth, providing the necessary foundation for industrialization, trade, and social mobility. However, the cost of capital in EMDEs remains structurally higher than in advanced economies, often by several hundred basis points. This premium is frequently detached from the actual performance of the projects themselves, instead reflecting broader sovereign risk perceptions and the regulatory burdens placed on lending institutions.
Project finance, which is the primary vehicle for large-scale infrastructure development, is treated with high levels of conservatism under the Basel III rules. This conservatism manifests in both the Standardised Approach and the Internal Ratings-Based (IRB) approach used by banks to calculate capital requirements. Under these frameworks, banks must hold significantly more capital against EMDE exposure than against similar projects in developed markets. This "capital charge" is passed on to borrowers in the form of higher interest rates, often rendering high-impact projects financially unviable despite their potential for strong long-term returns.
Chronology of Regulatory Evolution and the Basel III Endgame
The journey to the current regulatory environment began in the late 1980s with the original Basel Accord, which established minimum capital requirements for banks. Following the 2008 financial crisis, the Basel Committee on Banking Supervision (BCBS) introduced Basel III to address the vulnerabilities exposed by the market collapse. These rules increased the quantity and quality of capital banks were required to hold and introduced new liquidity and leverage ratios.
In recent years, the focus has shifted to the "Basel III Endgame"—the final set of reforms intended to reduce the variability in risk-weighted assets (RWA) across global banks. However, as these final rules are implemented across different jurisdictions, industry experts and international bodies like the International Chamber of Commerce (ICC) have noted that the framework does not sufficiently account for the unique risk profiles of project finance in emerging markets. The timeline of implementation has seen various delays, yet the underlying conservative bias against EMDEs has remained a constant feature of the regulatory landscape.
The Disconnect: Risk Performance vs. Regulatory Perception
The most compelling argument for reform lies in the data regarding project finance performance. Historical data from the Global Emerging Markets Risk Database (GEMS), which compiles the credit performance of multilateral development banks (MDBs) and development finance institutions (DFIs), consistently shows that project finance in EMDEs often exhibits lower default rates and higher recovery rates than comparable corporate lending.
For instance, Moody’s Investors Service has historically reported that project finance loans globally have a cumulative default rate that stabilizes over time, often behaving like investment-grade debt after the initial construction phase. Despite this evidence, Basel III rules often ignore the "de-risking" that occurs once a project becomes operational. Furthermore, the framework limits the recognition of credit enhancement tools—such as guarantees from MDBs or private insurance—which are specifically designed to mitigate the risks that the regulations seek to guard against.
Technical Adjustments: A Path to Immediate Relief
The International Chamber of Commerce has proposed a practical agenda for reform, beginning with a series of technical adjustments. These are designed to be "low-hanging fruit"—clarifications that can be issued by the Basel Committee without rewriting the core treaties. These adjustments focus on the following areas:

- Recognition of Credit Risk Mitigation (CRM): Clarifying that first-loss guarantees and other sophisticated credit enhancement tools should be fully recognized in capital calculations. Currently, the inconsistent application of CRM rules means that even when a project is backed by a highly rated multilateral institution, the lending bank may not receive the full capital relief that the guarantee should provide.
- Granular Risk Weighting: Moving away from broad-brush country risk overlays. At present, a high-quality project with stable cash flows can be penalized simply because of its geographic location. Technical guidance could allow for a "look-through" approach where the strength of the project’s collateral and contractual structure takes precedence over the sovereign ceiling.
- Treatment of Operational Phase Debt: Recognizing that the risk profile of an infrastructure project drops significantly once construction is completed and the asset begins generating revenue. Basel III could be adjusted to allow for lower risk weights during the operational phase of EMDE projects, mirroring the reality of their performance data.
Structural Reforms for Long-Term Sustainability
Beyond immediate technical fixes, a second stage of reform involves more fundamental structural changes. The ICC recommends that the Basel Committee be mandated to establish new work programs to align capital requirements with the global priority of the energy transition and sustainable development.
One such reform involves the "Credit Conversion Factors" for undrawn commitments in project finance. In many EMDE projects, funds are disbursed over several years. High capital charges on undrawn portions of these loans discourage banks from committing to long-term infrastructure developments. Adjusting these factors to reflect the controlled nature of project disbursements could unlock significant liquidity.
Another critical area is the promotion of "Synthetic Securitization." By allowing banks to transfer the risk of EMDE infrastructure portfolios to institutional investors through securitization, banks can free up their balance sheets to originate new loans. Current Basel rules make this process capital-intensive and complex, limiting its effectiveness as a tool for recycling capital into new EMDE projects.
The Role of Multilateral Development Banks and Private Sector Reaction
The reaction from the private sector has been one of cautious optimism tempered by urgency. Banking associations have long argued that without regulatory reform, the private sector cannot meet the financing demands of the UN Sustainable Development Goals (SDGs). "We are essentially fighting with one hand tied behind our backs," noted a senior executive at a global infrastructure bank during a recent industry forum. "The liquidity is there, and the projects are bankable, but the regulatory cost of holding those loans makes them too expensive for the end-user."
Multilateral Development Banks (MDBs) are also central to this dialogue. The G20 has recently called for MDBs to evolve their business models to better mobilize private capital. However, MDB officials point out that their efforts are often blunted by Basel III. When an MDB provides a partial credit guarantee to a private bank, the goal is to encourage that bank to lend more. If the bank’s regulator does not recognize that guarantee as a significant risk mitigant due to Basel constraints, the MDB’s intervention loses its catalytic power.
Broader Implications and the Path Forward
The implications of maintaining the status quo are profound. If EMDEs cannot access affordable finance for infrastructure, the global energy transition will likely fail. Developing nations will be forced to rely on cheaper, more carbon-intensive energy sources to meet their growth needs, undermining international climate agreements like the Paris Accord. Furthermore, the lack of essential infrastructure—roads, bridges, water treatment, and digital connectivity—will continue to trap millions in poverty, leading to increased economic migration and regional instability.
The proposed reforms to the Basel framework are not intended to weaken the safety and soundness of the global banking system. On the contrary, by aligning capital requirements with real-world data and the actual risk profiles of project finance, regulators can create a more stable and efficient financial ecosystem. Ensuring that capital is allocated where it is most effective, rather than where it is most "regulatory-efficient," is a prerequisite for a resilient global economy.
In conclusion, the bridge between global liquidity and EMDE infrastructure needs is currently blocked by a regulatory bottleneck. Targeted clarifications and structural reforms to Basel III represent a vital opportunity to clear this path. By recognizing the unique strengths of project finance and the efficacy of modern credit-risk-mitigation tools, the international community can unlock the private investment necessary to build a sustainable and equitable future for the Global South. The task now lies with the Basel Committee and national regulators to move beyond well-intentioned conservatism and embrace a data-driven approach to global infrastructure finance.
