Caribbean Urged to Scale Up Investment as IDB-OECD Report Maps Path to Resilient Growth

Caribbean nations must urgently accelerate investment and adopt more coordinated economic strategies to build resilience, close critical infrastructure gaps, and unlock sustainable growth, according to a major new report by the Inter-American Development Bank (IDB) Group and the Organisation for Economic Co-operation and Development (OECD).

The findings, outlined in the Caribbean Development Dynamics Report 2026: Investing in Sustainable and Resilient Development, were a focal point at the ONE Caribbean Ministerial Dialogue held on April 21 in Port of Spain, Trinidad and Tobago. The high-level forum brought together regional leaders, economists, and international partners to translate the report's recommendations into concrete policy action.

A Region Facing Structural Pressures—and Opportunity

The report paints a dual picture of the Caribbean: a region highly exposed to climate shocks, fiscal constraints, and global economic volatility, yet rich in untapped potential across sectors such as tourism, renewable energy, and the blue economy.

However, unlocking this potential requires a step-change in investment levels and a shift toward more integrated, forward-looking development strategies.

Participants at the ministerial dialogue emphasized that without decisive action, infrastructure deficits and climate vulnerabilities could continue to constrain growth and deepen inequality. Conversely, targeted investments could position the Caribbean as a global leader in resilient and sustainable development.

Three Pillars for Transformational Change

The report identifies three priority areas that are critical to reshaping the region's economic trajectory.

1. Deepening Regional Integration to Unlock Scale

A central recommendation is to strengthen regional cooperation, enabling countries to overcome the limitations of small, fragmented markets.

Deeper integration can:

• Amplify investment flows by creating larger, more attractive markets

• Reduce costs through shared infrastructure and services

• Strengthen institutional capacity and governance

• Enable large-scale projects that would be unviable at the national level

Initiatives such as the IDB's ONE Caribbean programme are highlighted as key enablers, providing a structured platform to align national priorities, develop regional project pipelines, and mobilise both public and private investment.

2. Embedding Resilience into Investment Planning

With the Caribbean among the most climate-vulnerable regions globally, the report stresses that resilience must be embedded at the core of all infrastructure and development planning.

Priority actions include:

• Investing in climate-resilient infrastructure

• Expanding early warning systems for natural disasters

• Strengthening public-private partnerships with built-in risk management

• Protecting natural assets that underpin economic sectors

The report also highlights the importance of leveraging the region's strengths—particularly in the blue economy, renewable energy, tourism, and creative industries—to drive sustainable, long-term growth.

By integrating resilience into planning, countries can reduce long-term fiscal risks and avoid the high costs associated with disaster recovery.

3. Diversifying Financing to Meet Investment Needs

One of the most pressing challenges is the scale of financing required. Public budgets alone are insufficient, making it essential to diversify funding sources.

The report calls for a broader financing mix, including:

• Enhanced domestic resource mobilisation

• Greater private sector participation

• Increased access to international capital markets

It also highlights the growing role of innovative financial instruments, such as:

• Green, social, sustainability, and blue bonds

• Debt-for-nature swaps

• Resilient debt clauses that provide relief following climate shocks

These tools can help Caribbean countries access capital while aligning with global sustainability and climate objectives.

From Dialogue to Delivery

The ONE Caribbean Ministerial Dialogue served as a platform to move beyond analysis toward implementation. Leaders and stakeholders discussed practical steps to strengthen coordination, accelerate project development, and ensure that investments translate into tangible benefits for citizens.

There was strong consensus that regional collaboration will be key to overcoming shared vulnerabilities and achieving economies of scale.

A Blueprint for Inclusive and Resilient Growth

The 2026 report builds on earlier editions, offering a more urgent and actionable roadmap for the region's future.

Its core message is clear: investment in resilience is not optional—it is fundamental to economic stability and long-term prosperity.

By deepening integration, embedding resilience, and unlocking diverse financing pathways, Caribbean nations have an opportunity to transform structural challenges into drivers of growth—creating more inclusive, sustainable, and shock-resistant economies.
