The source and scope of the estimate

McKinsey estimates global infrastructure investment needs of approximately US$106 trillion through 2040, including about US$70 trillion in Asia. The estimate appears in its September 2025 report, The infrastructure moment, and is referenced in its 2026 Global Private Markets Report: Infrastructure. It is an external estimate, not a LupoToro forecast.

The framework spans transport and logistics, energy, digital systems, social infrastructure, agriculture, water and waste, and defence. Readers should consult the original report for its definitions, estimation approach and geographical breakdown. The figure describes modelled investment needs; it does not represent committed funding or a portfolio of commercially viable projects.

LupoToro perspective: translate demand into project questions

For a sponsor or public institution, a global estimate is the beginning of an assessment. A useful next step is to identify which local constraints prevent a particular project from proceeding and who is responsible for resolving them.

For example, a proposed data centre should be assessed through its power connection, cooling design, customer commitments, equipment availability and operating responsibilities. Each dependency needs an owner, a timetable and evidence supporting the delivery assumption. This is a practical assessment framework rather than a forecast of sector returns.

Questions for the investment decision

  • Demand: Which customers or public needs support the project, and what commitments substantiate that demand?
  • Delivery: Which permissions, site conditions, utility connections and specialist resources determine the schedule?
  • Economics: How do cost escalation, delays, financing terms and lower utilisation affect the proposal?
  • Responsibility: Which risks sit with the developer, operator, financiers and public counterparties?
  • Resilience: Which external dependencies could interrupt operation, and what alternatives are feasible?

From sector interest to an executable proposal

Project preparation should produce an evidence register, a dependency map and a clear list of unresolved decisions. Private capital, public funding and other financing routes can then be considered against the actual operating model. Large expenditure forecasts do not settle questions of ownership, affordability, procurement or risk allocation.
