The G20 Is a Failure, But Can It Do Better to Correct Past Mistakes?
World leaders heading to the G20 summit should use this rare multilateral space to advance a more equitable and sustainable global economy. Will they?
Nov 15, 2025
Multilateralism is in tatters. Instead of rules-based, consensus agreements, global economic relations have largely devolved into one-on-one arm-twisting and name-calling, alternating with fawning sycophancy and lavish personal gifts. In recent negotiations with Asian leaders, President Trump scored a gold golf ball, a gold crown, and a gold-flecked dessert.
In a world already divided by extreme inequalities, the collapse of multilateralism makes it even more likely that the most powerful players — the largest economies and the wealthiest corporations and individuals — will score the best deals. Small countries and ordinary people, from Iowa soybean farmers and Mexican factory workers to digital service consumers in Cambodia, are even more likely to get the shaft.
The G20 is a space that was intended to catalyze multilateral action. In fact, it touts itself as the “the premier forum for international economic cooperation,” and it is the one place where leaders of the world’s largest economies sit down together at least once a year for face-to-face dialogue.
South Africa will host this year’s G20 summit from November 22 to 23, and the United States will host the next one in December 2026. Do we have any reason to think this forum holds potential for not only restoring multilateralism but also advancing a more equitable global economy?
This is a question I’ve grappled with over the past several months as part of a team of analysts from the UK, Brazil, South Africa, and other countries. In our new joint report, The G20 at a Crossroads, we document a few examples of decisive actions this body has taken during its nearly two decades of existence.
In the midst of the financial crisis that erupted in 2008, for instance, labor unions and others successfully lobbied G20 leaders to adopt coordinated stimulus measures that helped avoid a depression-level global collapse.
In response to the Covid-19 pandemic, the G20 approved of at least some debt relief for low-income countries and authorized $650 billion in financial aid in the form of “special drawing rights,” the largest-ever allocation of this IMF-created international reserve asset.
These actions were far from perfect. Governments prematurely aborted the stimulus programs they adopted after the 2008 crash in favor of austerity budgets that deepened and prolonged economic crises.
Pandemic support programs were woefully insufficient for the poorest countries and failed to prevent many of them from sinking even further into debt. Between 2019 and 2023, Sub-Saharan Africa’s total external debts increased from $747 billion to $864 billion while the number of global billionaires grew from 2,153 to 2,640. Overall, 3.4 billion of the world’s people live in countries that spent more money in the years 2021-2023 servicing their foreign debts than on public education or health.
What can we learn from these examples? G20 leaders obviously have the power to mobilize vast resources, but the few times they’ve used this power, the focus has largely been on containing market crises to protect the interests of the wealthiest creditors and investors rather than improving the lives of the most vulnerable.
And so while we need to push for renewed multilateralism, we cannot be satisfied with a return to old models. We need new approaches that go beyond crisis management to build a more resilient, sustainable, and just global economy for the long term.
To achieve this, the G20 must tackle what we describe in our report as the “lived crises of our time” — the daily realities of extreme droughts, food insecurity, unaffordable housing, precarious work, debt traps, and forced displacement.
Decades of neglecting these threats to global stability has undercut the welfare of people in both the Global North and South. High levels of poverty and unemployment in the developing world, for example, weaken the bargaining power of U.S. workers who are competing in a global labor pool.
Climate change, obviously, knows no boundaries. And skyrocketing inequality is fueling political polarization, authoritarianism, and xenophobia around the world, as elites deflect blame onto migrants and other convenient scapegoats instead of confronting structural failures.
Last year, the Brazilian presidency took important steps towards broadening the G20 agenda. Through diplomacy, sustained civil society engagement, and collaboration with innovative academics, they elevated critical proposals for clean energy financing, taxing extreme wealth, and valuing care work. And while they did not secure G20-wide cooperation on these fronts, their efforts gave a boost to campaigns in numerous countries for increasing taxes on billionaires and ensuring decent pay for caregivers and affordable care for those who need it.
“Wherever we live, we all want the same things — a secure place to live, a healthy environment, the ability to care for our loved ones, and the chance to plan for our future,” notes our lead report author, Fernanda Balata, of the New Economics Foundation.
With political will and a commitment to cooperation, G20 leaders have the power to deliver these basic elements of a dignified life to billions of people.

500+ Experts Worldwide Call for Global Panel to Address ‘Inequality Emergency’
"Clear and proven steps can be taken to reduce it and build more equal societies and economies," wrote economists and other experts, "which are the fundamental foundation stone of a successful future for us all."
Nov 14, 2025
Emphasizing that economic inequality is "a policy choice," more than 500 economists and other experts on the global wealth gap are endorsing a call made earlier this month in the first-ever G20 report on inequality: The "inequality emergency" must be confronted by new international body inspired by the United Nations' panel on climate change.
The creation of an International Panel on Inequality (IPI) was a central recommendation of the landmark report set to be presented next week at the G20 Leaders Summit in Johannesburg, and renowned economists including 2024 Nobel economics laureate Daron Acemoglum, Thomas Piketty, Isabella Weber, Ha-Joon Chang, and Jason Hickel were among those who signed a letter Thursday urging the creation of the committee.
The inclusion of economists, climate scientists, epidemiologists, historians, and experts from a range of other disciplines "reflects a key fact," said the signatories. "High levels of economic inequality have a negative impact on every aspect of human life and progress, including our economies, our democracies, and the very survival of the planet."
"Just as the Intergovernmental Panel on Climate Change (IPCC) has played a vital role in providing neutral, science-based, and objective assessments of climate change, a new International Panel on Inequality would do the same for the inequality emergency," reads the letter, which was also signed by global economic leaders including former US Treasury Secretary and Federal Reserve Chair Janet Yellen and former World Bank top economists and leaders.
Since its inception nearly four decades ago, the IPCC has provided governments with the most up-to-date scientific information about planetary heating and its impacts. Its assessments have informed the creation of the United Nations Framework Convention on Climate Change; the 1997 Kyoto Protocol, which subjected wealthy countries to emissions targets for the first time; and the 2015 Paris Agreement, which has required countries to develop and implement plans to draw down planet-heating emissions.
An IPI, said the experts on Thursday, "would provide policymakers the best, most objective assessments on the scale of inequality, its causes and consequences, and consider potential solutions."
"We believe this is in the interests of policymakers from across the political spectrum, who see the importance of this issue and the need to base responses to it on data and evidence and sound analysis," reads the letter. "We know that scholars and experts across the world would readily contribute their time voluntarily—as thousands do for the IPCC—in support of such a necessary and vital international initiative. We are ready to assist in this process."
The letter followed the release of the G20 Extraordinary Committee of Independent Experts on Inequality's landmark report, which was presented to South African President Cyril Ramaphosa earlier this month ahead of the G20 Leaders Summit.
The Extraordinary Committee, which is led by Nobel Prize-winning economist Joseph Stiglitz and also includes inequality experts such as Winnie Byanyima of Uganda and Jayati Ghosh of India, warned that in the last quarter-century, the wealthiest 1% of people around the globe have captured more than 40% of all new wealth—$1.3 million on average—while the bottom 50% has seen its wealth grow by just 1%, or about $585, in constant US dollars.
One in four people around the globe—roughly 2.3 billion people—face moderate or severe food insecurity, meaning they regularly skip meals. The report found that the problem is getting significantly worse, with the number of food-insecure people rising by 335 million since 2019.
The report found that 80% of all countries—accounting for roughly 90% of the global population—have high levels of income inequality, making them seven times more likely than more equal countries to experience democratic decline.
“We are at a dangerous moment in human history," said Piketty, co-director of the World Inequality Lab and World Inequality Database. "Rampant inequality is dividing nations and communities, threatening our social fabric, human rights, and the very essence of democracy. A global effort to tackle inequality is needed—and rigorous analysis of its causes, drivers, and solutions is the first step."
"Governments need to live up to the G20 Summit’s promise of ‘solidarity, equality, sustainability’ and urgently establish an International Panel on Inequality," he added.
Countries with low levels of inequality included Norway, Sweden, Denmark, and Finland—places that also consistently rank high on global reports on happiness and that were found to have low levels of "health, social, and environmental problems," according to the report.
The countries with low levels of inequality have "generous universal transfers and social insurance, supplemented by targeted assistance," the report says.
“High inequality is the result of decades of a failed economics that has primarily benefited the richest in our societies," said Chang, research professor at the School of Oriental and African Studies at University of London. "Not only is there a lot of evidence showing that higher inequality produces more negative economic and social outcomes, there are quite a few examples of more egalitarian societies growing much faster than comparable but more unequal societies.”
The signatories of the letter emphasized that inequality "is not inevitable."
"Clear and proven steps can be taken to reduce it and build more equal societies and economies," they wrote, "which are the fundamental foundation stone of a successful future for us all."

$70 Trillion in Inherited Wealth Shows Global 'Inequality Emergency' Spiraling Out of Control
"Inequality is a crisis in need of concerted action," said Nobel Prize-winning economist Joseph Stiglitz.
Nov 04, 2025
A panel of experts convened by South Africa's president warned Tuesday that the world is facing an "inequality emergency" as the richest people on the planet capture a disproportionate share of new wealth and prepare to pass it down to their heirs—perpetuating the chasm between economic elites and everyone else.
The panel, led by Nobel Prize-winning economist Joseph Stiglitz, notes in a new report that over $70 trillion in wealth will be passed down to heirs over the next decade. In the next 30 years, the panel estimates, 1,000 billionaires will transfer more than $5.2 trillion to their heirs mostly untaxed.
"Inequality is one of the most urgent concerns in the world today, generating many other problems in economies, societies, polities and the environment," states the report, published ahead of the G20 meetings in Johannesburg at the end of the month.
Joining Stiglitz on the panel, formally called the Extraordinary Committee of Independent Experts on Global Inequality, were Adriana Abdenur of Brazil, Winnie Byanyima of Uganda, Jayati Ghosh of India, and Imraan Valodia and Wanga Zembe-Mkabile of South Africa.
"Inequality is not a given; combating it is necessary and possible," the experts wrote. "Inequality results from policy choices that reflect ethical attitudes and morals, as well as economic trade-offs. It is not just a matter of concern for individual countries, but a global concern that should be on the international agenda—and therefore the G20's."
Since 2000, the global 1% has captured more than 40% of all new wealth while the bottom half of humanity saw its wealth grow by just 1%, according to the new report. More than 80% of countries—accounting for roughly 90% of the global population—have high levels of income inequality, which undermines social cohesion, economic functioning, and democratic institutions nationally and worldwide.
The panel recommends a broad scope of policy changes to tackle runaway income and wealth inequality, from ensuring the fair taxation of multinational corporations and ultra-rich individuals, to antitrust policies that reduce corporate concentration, to major investments in public services.
The experts also called for the creation of an International Panel on Inequality—inspired by the Intergovernmental Panel on Climate Change (IPCC)—"to support governments and multilateral agencies with authoritative assessments and analyses of inequality" that would "empower policymaking."
"The committee's work showed us that inequality is a crisis in need of concerted action," Stiglitz said Tuesday. "The necessary step to taking this action is for policymakers, political leaders, the private sector, journalists and academia to have accurate and timely information and analysis of the inequality crisis. This is why our recommendation above all is for a new International Panel on Inequality."
"It would learn from the remarkable job the IPCC has done for climate change, bringing together technical expertise worldwide to track inequality and assess what is driving it," he added.
