The financing gap
Responsibility for building and maintaining infrastructure has historically rested squarely with governments. Funded through public expenditure, this approach worked well under economic conditions that supported expansive budget allocations for critical public works. But the traditional model hit stumbling blocks in recent decades. It’s unlikely that today’s governments can pay for all the necessary infrastructure construction and maintenance on their own. That’s in large part because of the debt they carry, which has tripled since the mid-1970s, and now sits at 92% of global GDP4.
The situation across developed markets requires a strategic pivot toward private capital to bridge this funding gap. Private investors are meeting the need, led by institutional investors like large pensions.
These new investors have brought fresh capital to the table, stepping in to assume roles traditionally held by governments. They have acquired and managed municipal assets worldwide, with a mandate to try and optimise returns. This model aims to reduce the financing gap but also introduces a new dimension of efficiency and innovation in infrastructure management, leveraging private sector expertise.
Today, the transformation in infrastructure financing is evident. A broad spectrum of assets, from airports to railroads to water systems, now falls under this privatized management model, opening new investment avenues and highlighting the crucial role of capital in infrastructure development.
Investors now play a significant role in maintaining the infrastructure networks vital for economic growth and societal advancement. Often these investors can partner with government entities who can offer a reliable partnership, sharing some of the risks that accompany infrastructure projects. Public-private partnerships can take a variety of forms, such as private investors taking an equity stake in an airport or an operating agreement that could mean locking in long-term contracts, securing long-term cashflows. Low- and middle-income countries are frequent users of the public-private structure.
