A proposal for an International Panel on Inequality (IPI) is gaining significant traction among global leaders and scientists, aiming to bridge the gap between complex economic data and actionable policy. The initiative calls for an independent scientific body modeled after the Intergovernmental Panel on Climate Change (IPCC) to systematically evaluate the causes, consequences, and policy responses to global disparity.
The push follows a 2025 report submitted to G20 nations by the G20 Extraordinary Committee of Independent Experts on Global Inequality, chaired by J.E.S. and invited by South African President Cyril Ramaphosa. The committee’s primary recommendation was the establishment of the IPI. Since then, a founding committee led by South Africa, Brazil, Spain, and Norway has been developing the framework. The effort has secured the endorsement of United Nations Secretary-General António Guterres, unanimous support from the African Union, and backing from more than 600 economists and inequality specialists.
The urgency stems from stark statistics: the richest 10% of adults globally capture 53% of income, while the poorest half receives only 8%. Wealth concentration is even more severe, with the top 10% owning approximately three-quarters of global wealth and the bottom 50% holding just 2%. Nearly two-thirds of the world’s population resides in countries where inequality is currently rising.
Research increasingly links high inequality to reduced social mobility, poorer health outcomes, slower economic growth, and democratic erosion. Countries with higher inequality are seven times more likely to experience the undermining of checks and balances and the rise of authoritarian practices than their more equal counterparts.
Despite general consensus that inequality is a critical issue, policymakers face significant hurdles due to fragmented and often contradictory data. For instance, estimates of India’s Gini coefficient varied widely in 2022, ranging from 0.25 according to the World Bank to 0.64 by the World Inequality Lab. Such discrepancies arise because household surveys often underrepresent top incomes, and different methodologies yield divergent results.
The proposed IPI would address these gaps by standardizing measurement techniques, clarifying the drivers of inequality—such as tax structures, wage-setting, and inherited wealth—and synthesizing evidence on which policies succeed in different contexts. With an estimated $70 trillion in intergenerational wealth transfers expected over the next decade, the panel aims to provide the robust data foundation necessary for governments to combat disparities effectively.
I’m skeptical about the funding. $70 trillion in wealth transfers is huge, but will governments really prioritize spending on this panel?
Seven times more likely to see authoritarianism? That statistic alone should scare every democracy into action immediately.
The disparity in Gini estimates is staggering. Standardizing data is crucial before any policy can actually work effectively worldwide.
Why has it taken so long to propose this? The IPCC model worked for climate; inequality deserves the same urgency and scientific rigor.
Good idea, but without enforcement power it will just be another talk shop. I hope they can actually compel data transparency.
