Highlighting a projected $15 trillion global infrastructure investment gap by 2040, the focus is on the inefficiency and insufficiency of current expenditure. Exploring private sector infrastructure funds, the emphasis is on the appeal to investors and the substantial unallocated capital, with a proposal to address risk management through innovative public-private partnerships to unlock essential project funding.

Public-Private Partnerships (PPPs) leverage private partners to provide public goods with reduced state capital at risk, making them attractive amid debt crises. PPPs, such as Canada's Samuel de Champlain Bridge, benefit from efficient risk management during construction, though optimal risk allocation requires careful negotiation to address complexities and viability gaps, ensuring the alignment of incentives for both parties.
