The 2026 G20 finance ministers’ discussions have placed the reform of the International Monetary Fund (IMF) and the World Bank at the centre of the international financial architecture agenda. The focus is not on a wholesale redesign of the system, but on implementing reforms already agreed, strengthening financial capacity and improving the institutions’ ability to respond to debt pressures and changing global economic conditions.
IMF: from agreement to implementation
A key issue for the IMF in 2026 is the implementation of the 16th General Review of Quotas, approved in December 2023. The reform envisages a 50% increase in IMF quotas, strengthening the Fund’s permanent resources and reducing its reliance on borrowed resources. Its full implementation, however, still depends on domestic approval processes across the membership. In May 2026, the IMF Executive Board extended the consent period for the quota increase to 15 November 2026.
The reform also highlights a broader governance question. The 16th quota increase is equi-proportional and therefore does not change relative voting shares. A more significant adjustment of quotas to reflect changes in the global economy has been deferred to the next review.
The Diriyah Guiding Principles for Quota and Governance Reforms, adopted in 2025 and welcomed in 2026, provide a framework for the next stage. They emphasise transparent and merit-based leadership selection, protection of the representation of the poorest members and greater voice for emerging market and developing economies. The forthcoming 17th General Review of Quotas is therefore expected to address the more complex question of how voting power and representation should evolve over time.
World Bank: increasing development finance capacity
The World Bank reform agenda has focused on making better use of existing financial resources. The G20’s work on multilateral development banks, together with the Capital Adequacy Framework recommendations, aims to increase lending capacity while maintaining appropriate levels of financial resilience.
The underlying objective is to enable multilateral development banks to finance more development, infrastructure, climate and resilience projects without requiring a proportional increase in new shareholder capital. Better use of existing balance sheets, improved risk management and portfolio optimisation could increase lending capacity over time.
At the same time, greater lending capacity needs to be accompanied by stronger frameworks in borrowing countries, particularly in areas such as debt transparency, domestic revenue mobilisation and investment conditions. The objective is therefore not simply to increase financing, but to make that financing more sustainable and effective.
Debt sustainability and coordination
Debt sustainability is one of the areas where IMF and World Bank reforms have the most immediate practical relevance.
At the September 2026 G20 finance ministers’ meeting in Asheville, the two institutions highlighted a joint three-pillar approach for countries facing high debt-service burdens while maintaining potentially sustainable debt positions. The approach combines liquidity and financing support, debt sustainability analysis and restructuring where necessary, and measures aimed at improving debt transparency, data quality and relations between borrowers and investors.
The continued strengthening of the G20 Common Framework for debt treatments remains an important part of this agenda. The broader challenge is to make debt restructuring more predictable and efficient while ensuring that responsibilities are appropriately shared among official creditors, private creditors and multilateral institutions.
Governance and representation
A further dimension of the reform process concerns the representation of emerging and developing economies within the Bretton Woods institutions.
The debate is increasingly focused not only on the size of quotas, but also on how governance and leadership should reflect changes in the global economy. The objective expressed by several groups of emerging and developing economies is greater representation in decision-making and more inclusive leadership processes.
The Diriyah Principles provide a common framework for this discussion, while the 17th General Review of Quotas will determine how far these principles are translated into concrete changes in voting power and representation.
The broader direction of reform
The 2026 G20 finance agenda points towards an incremental but significant evolution of the international financial architecture.
For the IMF, the immediate priority is to complete the 16th quota reform and establish a credible path towards the next review. For the World Bank and other multilateral development banks, the emphasis is on increasing financial capacity through more efficient use of existing capital.
Debt sustainability provides a practical area where these two strands increasingly converge. Closer coordination between the IMF and World Bank can help combine macroeconomic stabilisation, development financing and debt-management measures, particularly in countries facing limited fiscal space.
The reform process also reflects a broader need to maintain the legitimacy and effectiveness of the Bretton Woods institutions in a changing global economy. Greater representation of emerging and developing economies, transparent governance and stronger institutional capacity are becoming increasingly important elements of that legitimacy.
The central challenge for the coming years will therefore be implementation: translating agreed principles into stronger financial capacity, more effective debt solutions and governance arrangements that remain credible across a diverse international membership.
The 2026 G20 finance track has established the main elements of this agenda. The next phase will determine how quickly and effectively these reforms can be implemented and whether the IMF and World Bank can continue to provide a central framework for international monetary stability, development finance and coordinated responses to global economic pressures.
