BII Targets £15bn Investment by 2031
British International Investment launched a five-year strategy to mobilize private capital in developing economies as UK aid budgets shrink.
Updated on Nov. 5, 2026 in Business Strategy
British International Investment launched its five-year strategy on April 22, 2026, aiming to drive £15bn into target countries by 2031. BII will provide around £8bn from its own capital, with private investors supplying the remaining £7bn.
Why it matters
The UK government cut its aid budget significantly, prompting BII to rely more heavily on private capital to fund development projects. The strategy reflects a broader shift toward using public money to de-risk investments that attract commercial investors.
BII's five-year plan commits £8bn of its own capital and targets £7bn from private investors, with a goal of crowding in almost £1 of private capital per £1 invested. Its target for the share of new capital going to Least Developed Countries is 25%, but the source does not report how this compares to the prior period's allocation.
The players
British International Investment (BII)
BII is the UK government's development finance institution that invests in private sector projects in lower-income countries.
The details
BII will deploy public capital to de-risk projects and attract commercial investors, using investment clusters, strategic investments that unlock competition, and whole asset-class development. The strategy also raises gender finance to 30% of new core investments from 25%, and climate finance to 40% from 30%.

Business Strategy Shift
BII's plan reflects a move by development finance institutions to crowd in private investment as public aid budgets contract, a pattern visible across G7 countries facing declining fiscal resources. The strategy aims to crowd in about 40% more private capital than its previous strategy period.
For readers following development finance, BII's strategy signals that more aid-linked investment in developing economies will be routed through private capital mobilization rather than direct public grants. Shifts in how these funds are allocated may affect which projects in lower-income countries receive financing.
The takeaway
Development finance is increasingly built around leveraging limited public money to attract private investors. Watching whether BII meets its 2031 targets will show how well this model delivers capital where it is most needed.
