IDB Report Highlights PPPs as Key to Caribbean’s $21B Infrastructure Goal

The IDB estimates that the region will require over $21 billion in infrastructure investment by 2030 to meet development goals and close existing gaps.

 

Introduction: Unlocking the Caribbean’s Development Through Innovative Investment

In a bold call to action, the Inter-American Development Bank (IDB) has released a comprehensive new report emphasizing the urgent need for public-private partnerships (PPPs) and innovative financing mechanisms to drive infrastructure development and resilient growth across the Caribbean.

Titled “Catalyzing Capital: Public-Private Partnerships for Resilient Growth,” the report paints a detailed picture of the region’s economic challenges, infrastructure investment needs, and the critical reforms needed to unlock over $21 billion in infrastructure investment by 2030—a move that could generate more than $84 billion in additional economic output across Caribbean nations.

A Legacy of Slow Growth and High Vulnerability

According to the report, Caribbean economies have averaged less than 2% annual GDP growth since 1970—a sluggish rate attributed to a combination of structural constraints, limited fiscal space, high public debt, and heavy reliance on tourism and commodity exports. Many countries in the region remain acutely vulnerable to global economic shocks, climate-related disasters, and limited access to long-term capital.

As governments continue to face tight fiscal constraints, traditional models of infrastructure financing—predominantly through public expenditure—are no longer sufficient to meet the growing demand for modern, resilient, and inclusive infrastructure.

“Countries across the region need significantly larger volumes of private investment, expertise, and innovation to drive faster and more inclusive growth,” said Anton Edmunds, IDB General Manager for the Caribbean. “This report outlines the path forward.”

A $21 Billion Infrastructure Challenge—and Opportunity

Using IDB-developed methodologies, the report quantifies infrastructure gaps in the Caribbean across critical sectors, including:

• Transport (ports, airports, and road networks)

• Water and sanitation

• Energy infrastructure, particularly for renewable and resilient energy systems

• Digital telecommunications infrastructure, including broadband access and connectivity

The IDB estimates that the region will require over $21 billion in infrastructure investment by 2030 to meet development goals and close existing gaps. The figure excludes needs in social infrastructure such as hospitals, schools, and public housing—suggesting that true investment needs are even higher.

Why PPPs Matter: Efficiency, Innovation, and Risk Sharing

The report identifies PPPs as essential tools for bridging this massive investment gap. These partnerships allow governments to leverage private capital and expertise, improve service delivery, and accelerate project execution without overburdening public finances.

Key benefits of PPPs include:

• Efficient risk-sharing between public and private sectors

• Access to innovation and operational expertise

• Better long-term asset management

• Reduced upfront fiscal pressures on governments

• Accountability through performance-based contracts

The IDB emphasizes that, while well-structured PPPs can deliver high-quality infrastructure and services, robust institutional frameworks and policy reforms are essential to ensure transparency, protect public interest, and attract credible investors.

ONE Caribbean: A Regional Platform for Progress

Central to the IDB’s strategy is ONE Caribbean, a dedicated regional program that offers technical, financial, and project preparation support for Caribbean governments and private sector partners. The program is designed to:

• Improve regulatory environments and investment readiness

• Enhance regional cooperation and integration

• Support feasibility studies and public procurement reforms

• Mobilize blended finance and concessional capital where needed

“The IDB Group and our ONE Caribbean program can provide countries and firms with the tools needed to catalyze new investments in priority sectors,” said Edmunds.

Success Hinges on Enabling Conditions and Policy Reforms

While the potential of PPPs is clear, the report stresses that success will depend on a favorable enabling environment, including:

• Clear legal and regulatory frameworks for PPP implementation

• Stable macroeconomic and political environments

• Capacity building for government agencies in contract design and oversight

• Transparent project pipelines to attract investor interest

• Stakeholder engagement to build public trust

The IDB draws on global case studies to highlight best practices for PPP design and implementation, particularly in small island developing states (SIDS) with limited administrative capacity.

The Cost of Inaction—and the Promise of Growth

If Caribbean nations fail to scale up infrastructure investment, the region risks falling further behind in terms of competitiveness, resilience, and quality of life. Conversely, achieving the $21 billion infrastructure goal could unlock over $84 billion in economic growth, generate thousands of jobs, and make economies more robust in the face of climate and market shocks.

The report also suggests that digital and green infrastructure—especially renewable energy, smart grids, and broadband—offer the highest return on investment and the greatest potential to reduce inequality and empower underserved communities.

A New Era for Caribbean Development

The IDB’s latest report offers a compelling roadmap for how Caribbean nations can mobilize private capital, foster innovation, and build resilient economies through partnerships that go beyond traditional development financing.

As global financial conditions tighten and climate risks intensify, public-private partnerships are no longer optional—they are essential for the region’s future.

Policymakers, investors, and civil society stakeholders are now urged to come together under platforms like ONE Caribbean to take coordinated, high-impact actions that can turn the promise of resilient growth into reality.
