Asia-Pacific: Building out and up
The Asia-Pacific region remains the engine of global infrastructure growth, accounting for over 52.4% of total investment through the forecast period. Regional infrastructure spending will rise from $2.3 trillion in 2024 to $3.6 trillion by 2050—an increase of around 54%. Annual spending on transport, which accounts for 40.8% of total investment, will grow by 86% between 2024 and 2050, led by major expansions in roads, rail, and airports. Power sector investment will increase by around 51% over the period, with especially rapid growth in transmission and distribution (197%) and utility-scale storage (300%). Meanwhile, the rapid build‑out of digital infrastructure continues. Digital investment climbs by roughly 21% from 2024 to 2050, as data centres, fibre, and 5G networks expand across the region.
Advanced economies in the region, including Australia, Japan, New Zealand, and the Republic of Korea, are increasingly focused on the renewal of ageing assets, the expansion of digital and defence infrastructure, and the resilience of core networks. The Chinese Mainland will likewise pursue upgrades to its existing infrastructure and telecommunications networks. It will also focus on building out non-fossil energy systems, as well as energy transmission and storage facilities. In contrast, emerging economies—including India (3.8% CAGR to 2050), Indonesia (3.6% CAGR), the Philippines (3.2% CAGR), and Vietnam (4.3% CAGR)—will deliver some of the strongest growth in infrastructure investment, propelled by relatively young populations, rapid urbanisation, and policy aimed at closing infrastructure coverage gaps and boosting industrial capacity. (For a more detailed explanation of mature and emerging economies in Asia-Pacific, see the methodology section.)
Americas: US dominance and Latin American gaps
The five countries from the Americas covered in this report—Brazil, Canada, Chile, Mexico, and the US—collectively account for 95% of the region’s economic output, and together they’ll lift total infrastructure investment from around $1.2 trillion in 2024 to nearly $1.9 trillion by 2050, a 57% increase. Annual spending growth over the forecast 25 years will remain dominated by the US. Power and transport will lead spending across the region, each accounting for around 21.6% of total investment. As in the Asia-Pacific region, the expansion in data centres and fibre and 5G networks will result in investments in power and digital infrastructure that will become more closely linked. In transport, Brazil, Chile, and Mexico will prioritise connectivity and logistics; the US and Canada will focus on maintenance and modernisation of legacy assets.
Infrastructure needs and the level of development vary sharply across the region. In Latin America, gaps in basic infrastructure provision are most apparent in the levels of access and efficiency: the United Nations found that, in Brazil, only about 55% of the population has access to a safely managed sanitation system; and only one-sixth of roads across Latin America are regularly passable. In contrast, the US and Canada face challenges in infrastructure renewal and upgrading. Utilities across both countries record more than 260,000 water main breaks annually, costing around $2.6 billion in repairs. Although these needs are real, most of the attention will be focused on power generation to support the growth of digital infrastructure and, in particular, data centres.
Europe is entering a renewal-led super-cycle, with annual infrastructure spending projected to grow by 42% between 2024 and 2050 (from $641 billion to $909 billion). Funding will be directed towards reinvestment in ageing transport infrastructure (bridges, tunnels, rail), which accounts for about 30% of total spending. Defence infrastructure for logistics and for housing, training, and supporting personnel are also gaining greater prominence as Europe responds to new security realities. And given that the proportion of the 65-and-older population is set to reach 27% by 2050, spending on social infrastructure will rise from $145 billion in 2024 to $205 billion in 2050, making it the second-largest sector.
Western and Northern Europe leads in infrastructure spending, with Germany, the UK, and France investing most, especially in transport, power, and digital sectors. Norway will shift oil and gas infrastructure spending towards renewables and grid upgrades. Central and Eastern Europe shows the fastest relative growth, driven by transport and logistics, while Southern Europe is mixed: Türkiye’s rapid growth will be underpinned by urbanisation and transport; Spain and Italy will prioritise social infrastructure and power.
The Middle East: Economic diversification and digital transformation
The Gulf Cooperation Council (GCC) countries of the Middle East are delivering some of the world’s most ambitious multi-decade infrastructure build-outs. The region’s infrastructure spending, slated to grow 75% between 2024 and 2050 (from $200 billion to $349 billion annually), will be led by Saudi Arabia and the UAE, which together are projected to account for around 78% of the total. Across the GCC, economies are diversifying away from a historical dependence on oil and instead are pushing investment into model cities, industrial clusters, and digital and clean energy assets.
Recent developments in the region have also sharpened the strategic rationale for investment in infrastructure. Disruption to energy exports, shipping routes, and critical industrial inputs has highlighted the importance of resilient logistics, domestic industrial capability, and energy security. As a result, the region’s infrastructure story is no longer driven solely by growth and diversification—it’s also driven by resilience.
By 2050, transport will represent about one-quarter of total regional infrastructure spending, surpassing oil and gas. Power infrastructure—particularly renewables and batteries—will accelerate from a small base, with annual investment in renewables rising fivefold by 2050. Water infrastructure (including desalination and reuse) will double as the region addresses resource constraints, including water scarcity. Digital infrastructure, such as fibre networks and data centres, will become even more vital to economic transformation, alongside targeted spending in industrial and logistics assets.
Africa: Unmatched demand driven by demographic change
Africa’s fundamental development story means it will experience the fastest annual growth in infrastructure spending of any region over the 25-year forecast period. Aggregate annual spending across Ghana, Kenya, Nigeria, and South Africa is projected to increase from $54 billion in 2024 to $96 billion in 2050, a 77% gain.
Demographic change and urbanisation are the driving forces of growth in Africa. The continent is expected to add more than 800 million urban residents by 2050, and the number of megacities will triple. Spending on transport infrastructure, the largest sector, is projected to more than double as trade corridors expand. Agriculture and resources infrastructure will be the region’s second- and third-largest sectors in terms of spending over the forecast period.
