British International Investment pledged nearly £5 billion of its own capital to Africa over five years, anchoring a £9 billion total mobilization drive that surpasses its current Africa portfolio by 21% in the institution’s largest-ever commitment to the continent.

British International Investment, the UK’s development finance institution with £9.87 billion in net assets and stakes in more than 1,600 businesses across 66 countries, committed nearly £5 billion ($6.7 billion) of its own capital to Africa for the period 2026 to 2031 — a sum that exceeds its entire current Africa portfolio of $5.53 billion by 21%.

That pledge anchors a broader £9 billion Africa mobilization target. The remaining £4 billion ($5.4 billion) is expected to flow from private institutions based in Africa and globally, BII said in a statement published Thursday. Combined, the two tranches would generate approximately $12.1 billion of total investment impact across the continent over the five-year period — more than double the pace of the previous strategy cycle.

“By sharpening our focus on frontier markets, investing in high-impact sectors and mobilising domestic and international private capital, we are concentrating our efforts where our capital and expertise can make the greatest difference for African economies,” Chris Chijiutomi, Managing Director and Head of Africa at BII, said in the statement. Chijiutomi has overseen BII’s Africa operations during a period when the institution accelerated its annual deployment to the region to roughly £1 billion.

The announcement arrives at an inflexion point for development finance in Africa. Aid flows from the United States have declined, and several major European donors have contracted sharply over the past two years, removing billions of dollars that governments relied upon for health, education and budget support. The World Bank has argued that only private capital and accelerated industrialisation can close the resulting financing gap in response to current shocks — yet borrowing costs on international markets remain prohibitive for most sub-Saharan economies, limiting commercial flows into the very markets BII aims to catalyse. Whether pledged capital reaches frontier economies or concentrates instead in more bankable markets will prove as consequential as the headline figure.

Frontier push

Africa already dominates BII’s global book. The continent accounts for $5.53 billion — 60% of BII’s total portfolio — against $3.25 billion in Asia and $370 million in the rest of the world, according to the institution’s most recent portfolio data. Through 12 active direct investments and 90 active fund positions, BII holds exposure to 884 African businesses, ranging from payment processors and renewable energy platforms to agricultural finance vehicles. Its direct positions concentrate in financial services, infrastructure, food and agriculture, and technology.

The new strategy marks the sharpest formal frontier commitment in BII’s history, requiring at least 25% of new investments by value to flow to countries the United Nations designates as Least Developed Countries. BII named Sierra Leone and Zambia as priority markets where it would combine capital with policy engagement, technical assistance and partnership-building to dismantle the structural barriers that deter commercial investors, the statement said. At least 40% of new commitments will qualify as climate finance — up from 30% in the previous period — as the institution deepens its support for Mission 300, the World Bank-led initiative to connect 300 million Africans with electricity by 2030.

Jenny Chapman, the UK’s Minister for Development, framed the strategy as the operational expression of a deliberate shift away from grant-based aid. “Over the past few months, I have been setting out the need for a new UK approach to development — one moving from traditional aid grants to long-term partnerships that bring investment, expertise and international finance reform together,” Chapman said in the statement. BII, which receives capital from the UK government and operates at arm’s length from the Treasury, sits at the center of that transition as London seeks to recast its development profile.

Whether BII reaches the £9 billion Africa target will depend on its capacity to attract the projected £4 billion from commercial co-investors — a mobilization ratio the institution aims to improve by 40% compared with the previous cycle. New deployments will focus on financial services, power, transport, trade, digital infrastructure and sustainable industries, its strategy document stated. The first full test of the new framework is expected in BII’s 2027 annual report, as capital begins flowing under the strategy in the current quarter.
