WORLD - Developing countries face an annual financing gap of around $4 trillion to achieve the Sustainable Development Goals (SDGs), according to the United Nations’ 2026 Financing for Sustainable Development Report.

Rising debt costs, declining development assistance and limited access to investment are putting further pressure on public spending, the report said.

The report warns that the financing shortfall is emerging at a time when developing economies are already under pressure from weaker economic growth, geopolitical tensions, climate-related shocks and high borrowing costs.

The gap reflects the scale of additional investment needed each year in areas including infrastructure, health, education, social protection, climate action and other development priorities. 

The UN says closing it will require substantially greater public and private financing, alongside reforms to the international financial system.

Financing Falls Short of Development Needs

The funding challenge is not necessarily a shortage of money in the global economy. Rather, the report points to difficulties in directing financing toward countries and sectors where development needs are greatest.

Developing countries received almost $1.5 trillion in new external financial inflows in 2024. However, external financing accounted for only a limited share of total investment financing, while access to international capital remains more expensive and uneven than in developed economies.

At the same time, official development assistance (ODA) has weakened. UN data show that ODA fell 6% in 2024 to $214.6 billion and declined by a further 23% in 2025, putting additional pressure on countries that rely on concessional financing and international support.

Debt is Absorbing Scarce Public Resources

Rising borrowing costs are making the financing problem more difficult.

Developing countries’ external debt reached $11.7 trillion in 2024, while debt-servicing costs rose to about $920 billion. In the same year, developing countries spent almost 10% of government revenue on interest payments to foreign creditors.

UN Trade and Development (UNCTAD) also reported that developing countries paid $384 billion in interest on external debt in 2024. Over the previous decade, government interest payments increased by 102%, while government revenues rose by only 39%.

The result is less fiscal space for governments to invest in development. UNCTAD said 54 countries, representing 3.4 billion people, were spending more on debt servicing than on health or education.

A Widening Gap in Access to Finance

The financing squeeze is particularly severe for poorer and more vulnerable economies.

Least developed countries face some of the highest borrowing constraints and have greater difficulty attracting private investment. This creates a cycle in which countries with the greatest development needs can face the highest financing costs and the fewest available sources of affordable capital.

The UN’s 2026 report calls for international institutions to scale up financing, strengthen multilateral cooperation and reform the global financial architecture.

Without additional investment and more affordable financing, the report warns that the current financing trends could reverse development gains and make the SDGs increasingly difficult to achieve by 2030.
