In a world defined by rapid urbanization and digital innovation, the imperative to invest in infrastructure has never been clearer. From resilient highways to robust energy networks, these investments shape economies, connect communities, and drive sustainable growth. Yet, a significant funding gap threatens our collective progress.

Understanding the Investment Imperative

According to recent research, addressing infrastructure shortfalls requires a cumulative $106 trillion by 2040. Current projections fall short by $15 trillion, underscoring the challenge ahead. Annual investment must reach nearly 3.5% of global GDP – roughly $4.2 trillion each year for the next decade – to meet essential social, transport, energy, and digital infrastructure needs.

The distribution is uneven. Emerging markets account for two-thirds of the ten-year requirement, highlighting disparities between regions. Bridging this divide is essential to ensure equitable development and to foster inclusive, resilient communities around the globe.

Bridging the Funding Gap

Investor confidence is rebounding. In the first half of 2025, closed-ended funds raised $121.3 billion globally, surpassing the full-year total of 2024. This marks the first positive momentum since record volumes in 2022.

Key drivers include:

• Average fund sizes expanding to nearly $2.5 billion, the highest since 2015.
• Dominance of mega-funds, with the top ten responsible for over 80% of capital raised.
• Global mandates gaining traction, as funds with worldwide deployment strategies secured 55% of total capital.

This surge reflects a strategic shift towards diversified portfolios, combining energy transition projects with value-add hybrid assets to balance risk and return.

Regional and Sector Priorities

Investment needs vary by geography and sector. Developed economies, while established, still face substantial shortfalls:

• United States: Over $1 trillion needed over the next decade, particularly in road and energy networks.
• Europe: At least $500 billion through 2035 for core utilities and storage facilities.
• China: Approximately $1.5 trillion for non-energy infrastructure projects.
• India: Roughly $1 trillion required by 2035 for urban and rural connectivity.
• Latin America: A $150 billion annual gap, driven by trade diversification and friendshoring.

Sectoral breakdown reveals the broad scope of requirements:

Together, these sectors highlight areas ripe for innovation, partnership, and strategic deployment of resources.

Embracing Private Capital and Innovation

Private investment has transitioned from a supplemental role to the cornerstone of infrastructure finance. Assets under management in unlisted infrastructure have soared from under $25 billion in 2005 to over $1.5 trillion today.

To unlock further capital, stakeholders must:

• Align regulatory frameworks with investor expectations.
• Develop public-private partnerships that share risks and rewards.
• Leverage technological advances for faster, cost-effective delivery.

By integrating policy alignment, system design, and financial innovation, we can overcome structural barriers and accelerate project delivery across regions.

Maximizing Economic and Social Impact

Well-managed infrastructure investments generate outsized returns. For every million dollars deployed, an estimated 36,000 jobs are created, alongside a 1.5-fold GDP increase over five years. These impacts resonate through communities, fostering resilience, improving quality of life, and powering economic growth.

Beyond pure economics, infrastructure shapes societal well-being. Access to clean water, reliable electricity, efficient transportation, and digital connectivity underpins health, education, and entrepreneurship. Each project becomes a catalyst for empowerment, especially in underserved areas.

Actionable Strategies for Stakeholders

To translate potential into progress, collaboration is key. Policymakers, investors, operators, and communities must unite around shared goals. Here are practical steps:

• Prioritize projects with high social returns and environmental benefits.
• Employ robust risk mitigation tools, including blended finance and credit enhancements.
• Engage local communities early to ensure needs alignment and foster ownership.
• Adopt transparent reporting and performance metrics to build trust.
• Scale successful pilots through standardization and knowledge sharing.

Closing the infrastructure investment gap demands vision, persistence, and a willingness to innovate. By mobilizing capital effectively and aligning stakeholders around common objectives, we can transform funding shortfalls into opportunities for growth and resilience.

As we pave the way forward, every decision matters. Together, we can build infrastructure that not only withstands the challenges of tomorrow, but also enriches lives and strengthens economies today.
