Global FDI rebounded, but concentration changes what the headline means

What changed

Global foreign direct investment (FDI) recovered in 2025, but the strength of that recovery depends materially on the measure used. UN Trade and Development's World Investment Report 2026, released on 7 July 2026, estimates that FDI rose 6% to USD 1.6 trillion. The Organisation for Economic Co-operation and Development reports a 15% increase to USD 1.66 trillion, but its growth rate also falls to 6% after large fluctuations in selected European economies are excluded.

The two results should not be spliced into a single series. Their coverage and aggregation methods differ. They nevertheless point to the same caution for investors: Flows increased, but the underlying expansion after financial noise is removed was much less dramatic than the 15% headline suggests.

What the data actually say

UNCTAD says more than 80% of global FDI in 2025 went to the 20 largest host economies. Inflows to developed economies rose 11%, while developing economies recorded only 2% growth to USD 901 billion. Strategic sectors accounted for 44% of global greenfield project value, up from 16% in 2020. A small number of very large projects, particularly artificial-intelligence-related digital infrastructure, contributed materially to the increase.

The OECD adds another layer. In many countries, 2025 growth was driven mainly by intra-company loans and higher reinvested earnings. At the same time, both the number of announced greenfield projects and their expected capital expenditure declined. An economy can therefore record higher FDI without receiving a comparable increase in new factories, operating centres or businesses.

That is the distinction between capital recorded in the system and new productive capacity. Both can appear in FDI statistics, but their implications for employment, commercial property demand, supply chains and local business opportunity may be very different.

Who is affected

For Vietnamese business owners considering a foreign subsidiary, equity acquisition or operating site, an FDI ranking should be an initial screen only. It can show where multinational groups are allocating capital, but it does not identify the ultimate investor, the destination sector or whether the structure creates durable control and cash flow.

The distinction matters just as much for high-net-worth families. Buying a foreign fund, bond or listed share is portfolio investment, not FDI. The International Monetary Fund warns that portfolio flows to emerging markets can be more sensitive to global risk sentiment, particularly when intermediated by investment funds and other nonbanks. A rise in FDI cannot establish the liquidity or exit conditions of a listed security.

Capital, timing and obligations

Before using FDI data in a capital decision, an investor should ask four questions. First, is the flow equity, reinvested earnings or intercompany debt? ASEANstats includes all three in its definition of FDI transactions. Second, does it finance a new project, acquire an existing company or merely record a corporate reorganisation? Third, is the reporting economy the ultimate destination or a conduit? Fourth, does the family's or company's actual investment vehicle carry the same risks as the flow being measured?

Those questions also discipline the reading of the OECD's preliminary Q1 2026 figures. Aggregate global FDI reached an estimated USD 658 billion, up 44% from the previous quarter and 42% year on year. Excluding large fluctuations in selected European economies, the increases were 35% and 14%, respectively. The OECD says Czechia's increase was affected by a major corporate and financial restructuring, while Austria's was influenced by a large petrochemical merger and acquisition.

Risks and unresolved questions

Quarterly data are subject to revision. A single transaction can lift a country's ranking for one period without changing its long-term investment case. Net figures may also conceal substantial new investment and divestment occurring at the same time. Aggregate sector inflows say nothing by themselves about entry valuation, minority-shareholder rights, profit repatriation, tax, foreign-exchange controls or contract enforcement.

Developing Asia remains prominent, receiving USD 644 billion in 2025, about 40% of global FDI and more than 70% of flows to developing economies. UNCTAD says Southeast Asia overtook East Asia as the largest recipient subregion. That is a reason to examine sectors and countries more closely, not a recommendation to increase exposure across every Southeast Asian market.

The gap between UNCTAD's and the OECD's global totals is itself useful. It shows why investors should cite the institution, period, coverage and adjustment used, rather than presenting “global FDI” as if it were one uncontested number.

What to watch next

Investors should watch the OECD's revisions to see whether the Q1 increase survives fuller reporting, UNCTAD's country and industry tables, and ASEANstats breakdowns by source, destination and component. At transaction level, the next step remains an examination of ownership, revenue location, tax obligations, money-transfer routes and exit scenarios.

The useful message from the recovery is not that capital is moving everywhere. It is that aggregate flows are rising while becoming more concentrated, with a meaningful share explained by financial structures or very large transactions. For cross-border decisions, the quality and ultimate destination of capital matter more than the growth rate of the headline total.
