In a high-stakes keynote address delivered at IDB Invest Sustainability Week 2026 in Barbados on May 26, Caribbean Development Bank (CDB) President Daniel M. Best has issued an urgent call for a fundamental rethinking of how Caribbean nations fund development and climate adaptation, warning that inaction will lock the region into a self-reinforcing cycle of soaring debt, sluggish economic growth, and intensifying climate catastrophe.
Hosted by the Inter-American Development Bank’s investment arm, the annual sustainability gathering provided a critical platform for Best to outline the growing economic and environmental vulnerabilities facing small island Caribbean states. He pushed back against the incremental, piecemeal policy approaches that have dominated regional development efforts to date, calling for coordinated action from national governments, multilateral financial institutions, global investors, and private sector stakeholders to adopt ambitious, long-term strategies that match the scale of the region’s challenges.
According to Best’s projections, the Caribbean faces a total gross financing gap of roughly $65.2 billion over the coming 10 years. Of that, the region requires an estimated $14 billion annually to upgrade infrastructure and build systemic resistance to climate-driven disasters — yet currently, less than 10% of that required annual funding is actually secured.
A central pillar of Best’s proposal is a much larger role for the private sector in driving regional transformation. Rather than framing private actors as passive beneficiaries of development aid, he argued that private enterprise is the core engine of job creation, productivity gains, and sustained economic expansion across the Caribbean. “If we are serious about building resilient economies, then the private sector must be enabled, incentivised, and financed to lead that transformation,” Best said during his address.
Best laid bare the harsh economic realities that have held back the region for decades: crippling sovereign debt loads, constrained government budgets that leave little room for public investment, and repeated external shocks from climate disasters and global economic volatility. He added that even Caribbean nations with consistent, reliable debt repayment histories are still locked out of affordable lending, facing exorbitant borrowing costs that limit their ability to invest in long-term growth.
This dynamic, he explained, creates a vicious feedback loop: debt servicing payments crowd out critical public and private investment, constrained investment suppresses economic output, and slow growth in turn worsens fiscal vulnerability, sending countries back into deeper debt.
On the climate front, Best emphasized that climate risk is not a distant threat for the Caribbean — it is a current, existential crisis. Over the past eight years alone, the region has been hit by five Category 5 hurricanes, each causing billions in damage and setting back development gains by years. Rising sea levels and more frequent extreme weather events threaten to displace entire communities and wipe out decades of economic progress, he noted.
To break this cycle, Best highlighted innovative financing models as a critical path forward, pointing to the Multi-Guarantor Debt-for-Resilience Swap as a blueprint for action. This model brings together multiple guarantors to lower sovereign borrowing costs, reduce overall risk, and free up much-needed fiscal space for national governments. Rather than providing generic debt relief, the swap redirects funds that would have gone to debt servicing toward high-priority resilience investments, including public health infrastructure, climate adaptation projects, and disaster preparedness systems.
“At its heart, this swap is about partnership and choice,” Best explained. “This is not debt relief for its own sake. It is debt transformation — turning liabilities into opportunities, and obligations into investments in people, communities, and futures.”
Best stressed that no single actor can solve the region’s challenges on its own. Successful scaling of models like the debt-for-resilience swap requires deep collaboration between national governments, multilateral development banks, private insurers, commercial financial institutions, and global impact investors.
He also outlined the CDB’s ongoing work to expand private sector participation across the region, through blended financing structures, risk guarantees, co-investment partnerships, and targeted entrepreneurship programs that aim to improve the overall investment climate for local and international firms.
In closing, Best urged regional and international partners to move beyond endless discussion and take decisive, immediate action to address the Caribbean’s challenges. Against a backdrop of ongoing global economic volatility and uncertainty, he emphasized that regional collective action is the only path forward.
“The global environment is uncertain and volatile. And the reality is clear: no one is coming to rescue us. The responsibility rests with us — our institutions, our partners, and our people — to act collectively, to act boldly, and to act now,” Best said.
