According to the report, the amount of untaxed wealth held offshore by the richest 0.1 percent now exceeds the total wealth of the poorest half of humanity, or 4.1 billion people.
A decade after the Panama Papers exposed the hidden financial networks of the global elite, a new analysis by Oxfam reveals that vast sums of wealth remain beyond the reach of taxation — and larger than previously understood.
According to the report, the amount of untaxed wealth held offshore by the richest 0.1 percent now exceeds the total wealth of the poorest half of humanity, or 4.1 billion people.
The findings, published on April 2, 2026, underscore persistent gaps in global tax systems and renew calls for coordinated international action to address inequality.
RELEVANT SUSTAINABLE GOALS
Trillions Hidden in Offshore Tax Havens
Oxfam estimates that $3.55 trillion in untaxed wealth was held offshore in 2024, stored in tax havens and unreported accounts.
The scale of this wealth is striking. According to the organization, the total exceeds the gross domestic product of France and is more than twice the combined GDP of the world’s 44 least developed countries.
Within this pool, the concentration of wealth is highly uneven.
The richest 0.1 percent holds about 80 percent of all untaxed offshore wealth, or approximately $2.84 trillion. Within that group, the ultra-wealthiest 0.01 percent controls roughly half, amounting to about $1.77 trillion.
A Decade After Panama Papers, Little Has Changed
The analysis comes ten years after the Panama Papers first exposed how the wealthy use offshore structures to conceal assets and avoid taxes.
“The Panama Papers pulled back the veil on a shadow world where the richest quietly move immense fortunes beyond the reach of taxes and scrutiny,” said Christian Hallum, Oxfam International’s Tax Lead.
“Ten years on, the super-rich are still sequestering oceans of wealth in offshore vaults.”
Hallum described the issue as one that goes beyond financial strategy, pointing to broader social consequences.
“This isn’t just about clever accounting — it’s about power and impunity,” he said, noting that when wealth escapes taxation, public services such as hospitals and schools face funding shortages, while inequality continues to widen.
Progress Made — But Gaps Persist
Oxfam acknowledged that there has been some progress in recent years, particularly through mechanisms such as the Automatic Exchange of Information (AEOI) system, which allows countries to share financial data across borders.
These efforts have helped reduce the share of untaxed offshore wealth. However, the total remains high at about 3.2 percent of global GDP. The benefits of these systems are also unevenly distributed.
Many countries in the Global South remain excluded from the AEOI, despite having urgent needs for tax revenue. This gap limits their ability to track offshore assets and collect taxes from wealthy individuals.
In response to its findings, Oxfam is urging governments to take stronger and more coordinated action.
The organization is calling for enhanced international cooperation under the United Nations Framework Convention on International Tax Cooperation, alongside regional and global initiatives aimed at closing tax loopholes.
Among its recommendations:
- Strengthening tax authorities and financial transparency systems
- Creating tools such as a global asset register to track wealth
- Increasing effective tax rates on the richest individuals, including income from both labor and capital
- Introducing taxes on extreme wealth, particularly targeting the top 1 percent
Inequality at the Center of the Debate
At the heart of the issue is a widening gap between the wealthiest individuals and the rest of the global population.
Oxfam argues that without meaningful reforms, offshore wealth will continue to erode public finances and deepen inequality.
The report frames taxation not only as an economic issue, but as a question of fairness and public interest — one that directly affects governments’ ability to fund essential services and support long-term development.
As policymakers revisit global tax rules, the findings add urgency to a debate that has been building since the Panama Papers first brought the issue into public view.
