Key Facts

- The scale: roughly the equivalent of 10% of world output is held in tax havens, researchers estimate.

- The cost: tax havens are estimated to cost governments hundreds of billions of dollars a year in lost revenue.

- The trend: offshore wealth has grown over decades, though tax evasion has fallen with better data-sharing.

- The concentration: the share held offshore is far higher in Gulf states and some Latin American economies.

- Latin American impact: lost revenue limits what governments can spend on services and development.

Tax havens have expanded over decades, draining hundreds of billions in public revenue each year, and the offshore wealth they hold is especially concentrated in some Latin American economies.

How Big Are Tax Havens

The scale is large. Researchers led by economist Gabriel Zucman estimate that the equivalent of about 10% of world output is held in offshore tax havens. The figure has held near that level even as scrutiny has grown.

The revenue cost is steep. Studies put the loss to governments at hundreds of billions of dollars a year in unpaid taxes. Lower-income economies often bear a heavier hit relative to the size of their budgets.

One business report cited by La Republica put the offshore industry far larger still. That higher figure is harder to verify against independent estimates, which vary widely by what they count and how.

Why It Matters for Latin America

The regional angle is sharp. Zucman's work finds the share of wealth held offshore is far higher in some places, reaching around 60% in Gulf states and some Latin American economies, against a few percent in parts of Europe.

That concentration carries a cost. Money parked offshore is money that escapes local tax, narrowing what governments can spend on health, education and infrastructure. For developing economies, the gap can be large.

There is some progress. Researchers say automatic sharing of bank data has cut offshore tax evasion sharply over the past decade, though much wealth still sits beyond easy reach of tax authorities.

Frequently Asked Questions What is a tax haven?

It is a jurisdiction offering low taxes and financial secrecy that attracts wealth and corporate profits from elsewhere. Individuals and companies use them to lower or avoid tax bills.

How much money is involved?

Researchers estimate the equivalent of about 10% of world output is held offshore, with lost government revenue running into hundreds of billions of dollars a year. Estimates vary by method.

Is anything being done about it?

Automatic exchange of bank information across borders has reduced offshore tax evasion over the past decade. Loopholes remain, and a large stock of offshore wealth persists.
