Vietnam’s infrastructure buildout is moving on two tracks at once: record public investment plans and a revamped framework to bring in private capital. Mordor Intelligence values Vietnam’s infrastructure market at USD 19.61 billion in 2025 and estimates it will grow from USD 20.91 billion in 2026 to USD 28.81 billion by 2031, at a 6.62% CAGR. Transportation led with 47.86% of 2025 market share, while utilities are forecast to expand at an 8.58% CAGR through 2031. Yet the funding mix still leans public. In 2025, public funding captured a 72.88% share of the infrastructure market, while private investment is forecast to rise at a 9.06% CAGR between 2026 and 2031, underscoring why PPP rules and financing channels are now central to delivery.
State budgets remain the anchor. For 2026, the Prime Minister assigned nearly USD 39.8 billion in state budget-funded public investment, up 10.4% from 2025 and described as the highest level on record. But execution pace is a constraint that affects confidence across contractors and investors. In the first four months of 2026, public investment disbursement approximated 14.2% of the Prime Minister’s assigned target. Mordor Intelligence also flags delayed public disbursements and other execution risks, alongside contractor fragmentation and sand shortages that can inflate budgets and elongate project timelines. The result is clear: predictable processes and diversified funding are not just policy goals; they are practical requirements to keep projects moving from approval to construction.
PPP 2.0: Risk Sharing, Faster Approvals, and New Capital Channels
Vietnam’s PPP reforms in 2024 and 2025 are framed as a shift toward wider eligibility, streamlined procedures, and stronger risk-sharing mechanisms. Vietnam News links these changes to an effort to mobilise around USD 245 billion for major infrastructure and technology projects through 2030. The same report says the Ministry of Finance has received proposals from nearly 10 ministries and over 20 localities, identifying close to 80 potential projects related to digital infrastructure, data platforms, AI, smart cities, and co-operative innovation models. In parallel, a draft decree on public bond issuance by PPPs is under consultation by the Ministry of Finance and the State Securities Commission. According to Vietnam Investment Review, the draft could create a medium- and long-term funding channel for PPP projects and help complete the legal framework for capital mobilisation for large-scale infrastructure.
Project examples show how “sharing the load” can look in practice, including blended payments and sector-by-sector structuring. A Q2 2026 update notes a proposed complex on a 46.7-hectare site in Thu Thiem new urban area under a PPP build-transfer format, using a blended payment mechanism combining land allocation and state budget funds. In contrast, the same update cites PMU My Thuan recommending financing a large-scale railway project entirely through public investment, arguing that international experience indicates public funding can be more effective than PPP for such projects. This mix of approaches aligns with a broader theme: Vietnam PPP infrastructure investment is being designed around fit-for-purpose risk allocation, not a one-size-fits-all template.
Momentum is also visible in market structure and pipeline signals. Mordor Intelligence reports that, by investment source, public funding led Vietnam’s construction market with a 62.34% share in 2025, while private capital records the highest forecast CAGR at 8.89% to 2031. Within infrastructure, new construction accounted for 77.45% of the market size in 2025, showing how much of the agenda is still greenfield buildout. InCorp Vietnam highlights an expressway milestone: by end-2025, Vietnam had completed 3,345 km of expressways, and including interchanges and access roads, the operational network reached 3,803 km. It also points to Hanoi Capital Region Ring Road 4 with a preliminary total investment of VND 85,813 billion and a PPP/BOT component, including investor-arranged capital of VND 29,447 billion, with basic completion targeted in 2026 and operation from 2027.
