Infrastructure debt’s HALO shines bright

Infrastructure debt is positioned as a durable income and diversification opportunity because infrastructure investment needs are expanding while governments and banks are becoming less able to finance them.

• The estimated share of global infrastructure investment funded by private non-bank capital is expected to rise from 2–3% in 2013 to 12–13% in 2024 and 26% in 2034, while government funding falls from 70–75% to 55%.
• Higher rates support floating-rate infrastructure debt: the US policy rate of 3.50–3.75% is about 100 basis points above its long-term average, while floating-rate coupons reduce duration exposure.
• Four secular trends—digitalisation, decarbonisation, demographics and deglobalisation—are expected to require nearly US$20 trillion of infrastructure spending over five years and more than US$60 trillion over 15 years, against an annual funding gap of US$3.7 trillion.
• AI-related private credit has grown more than fivefold in five years, from roughly US$35 billion to nearly US$200 billion, and could reach US$300–600 billion by 2030; US fibre miles are projected to increase 2.3 times between 2024 and 2029.
• Decarbonisation is expected to drive US$5.9 trillion of global grid spending from 2026 to 2035, while unsubsidised utility-scale renewables have a levelised cost of US$40/MWh versus US$102 for gas, US$77 for coal and US$259 for nuclear.

Takeaway: Investors with traditional investment-grade fixed income may use infrastructure debt as a complementary income allocation, benefiting from contracted or regulated cash flows, potential inflation linkage and lower sensitivity to credit spreads, although the thesis depends on sustained infrastructure demand and private capital replacing public and bank funding.
