The international campaign against harmful tax practices was built around an appealing principle: companies should not receive preferential tax treatment simply because their activities or customers are located abroad. But for small island economies such as Curaçao, Aruba, Sint Maarten and Barbados, applying that principle raises a more complicated economic question.
What happens when tax equality between domestic and international activities produces unequal economic consequences between countries?
That is the central issue raised by the debate over “ring-fencing,” the practice of separating a preferential tax regime from the domestic economy, typically by making favorable treatment available primarily or exclusively to internationally oriented activities.
For Curaçao, this is not an abstract discussion about international taxation. Changes to such regimes have implications for the economic model the island historically used to compensate for disadvantages that larger economies simply do not have.
The Free Zone Was More Than a Tax Regime
Curaçao’s Free Zone historically performed an economic function extending beyond taxation.
Its importance was based on activity: goods arrived, warehouses were used, transportation services were required, foreign buyers visited the island and businesses employed local workers. That activity generated foreign exchange and created direct and indirect economic benefits.
This distinction matters.
If a tax incentive merely attracts profits that exist on paper while generating little employment or investment, its economic value to the jurisdiction is questionable. If an incentive attracts physical trade, employees, logistics, warehouses, investment and foreign customers, the calculation becomes considerably different.
Curaçao nevertheless had to adjust its tax system as international standards changed.
The 2018 tax reform legislation explicitly acknowledged the need to bring preferential regimes into conformity with standards developed by the OECD and European Union and to eliminate ring-fencing elements.
The policy objective behind those international standards is understandable. Governments should not facilitate artificial profit shifting, erosion of other countries’ tax bases or structures in which companies claim tax advantages without meaningful economic activity.
But accepting that objective does not answer a second question: what was the economic cost of compliance for Curaçao?
The Missing Cost-Benefit Calculation
That may be the most important question raised by the argument.
When an international organization evaluates a preferential tax regime, attention naturally falls on effective tax rates, government revenue, profit shifting and competition between jurisdictions.
A small island economy needs a broader balance sheet.
If eliminating or fundamentally restructuring an incentive causes economic activity to disappear, policymakers should also calculate lost employment, investment, logistics activity, foreign exchange earnings and spending elsewhere in the economy.
For Curaçao, that would mean asking how many jobs were associated directly and indirectly with the former Free Zone model; how much cargo and container traffic it generated; how much business went to transport companies, warehouses, customs brokers and other service providers; how much foreign currency entered Curaçao because of the activity; and where that business went after the model changed.
Without such an assessment, it is difficult to determine the net economic effect of the reform.
That does not mean the previous regime should necessarily have been preserved. It means that determining whether reform was economically beneficial requires more than demonstrating compliance with an international tax standard.
Small Economies Do Not Compete With the Same Weapons
This is where the issue becomes particularly relevant for Curaçao and other Caribbean jurisdictions.
A large economy can offer an investor millions of consumers, extensive infrastructure, deep capital markets, large pools of skilled labor and access to enormous domestic supply chains. Governments in larger economies may additionally use grants, subsidies, tax credits, industrial policy and public procurement to influence investment decisions.
Curaçao cannot replicate those advantages.
Its domestic market is small. Goods frequently have to be imported. Economies of scale are difficult to achieve, while transportation and infrastructure costs can be proportionately high.
International tax rules may therefore be formally neutral while having very different practical consequences.
A restriction that removes one competitive instrument from Curaçao does not simultaneously remove the scale, subsidies, infrastructure or market access enjoyed by a larger competitor.
That is the strongest economic argument for examining the ring-fencing prohibition through the perspective of small economies.
Formal equality does not automatically produce competitive equality.
Barbados Shows the Broader Caribbean Problem
The same underlying challenge extends beyond Curaçao.
Caribbean international financial centers have spent years adapting their tax systems to OECD and EU standards. Barbados, for example, moved away from the traditional distinction between international business companies and domestic companies as part of major corporate tax reforms.
The objective was essentially to remove the separation between preferential international activities and the domestic tax system.
From an international tax-policy perspective, such reforms create greater consistency.
From a development perspective, however, another question emerges: what policy instruments remain available to very small countries attempting to attract internationally mobile business?
That question becomes increasingly important as global corporate taxation moves toward greater standardization.
The danger for small economies is not necessarily that they will pay more tax themselves. It is that their ability to differentiate themselves as investment locations becomes progressively narrower while the structural advantages of large economies remain untouched.
The IMF Argument Adds an Important Dimension
One particularly interesting aspect of the argument is that modern thinking about tax incentives does not necessarily support simply judging them by the revenue governments surrender.
The IMF has argued that tax incentives in developing economies should be evaluated through systematic cost-benefit analysis.
That approach considers not only foregone tax revenue but also potential benefits such as investment, employment and wider economic spillovers.
Applied to Curaçao, that produces a much more sophisticated question than whether a preferential regime met international standards.
The relevant question becomes whether the total economic benefits generated by the incentive exceeded its fiscal and economic costs.
And that requires data.
If Curaçao cannot establish how much employment, investment, trade, foreign exchange and secondary economic activity its previous model generated, it is difficult to know whether the country ultimately gained or lost from changing it.
The Real Alternative Is Not a Return to the Past
None of this necessarily provides an argument for restoring the old offshore structures of previous decades.
The international tax environment has fundamentally changed. Transparency, beneficial ownership requirements, exchange of information and demands for genuine economic substance are now embedded in the global system.
Curaçao's more useful policy question is therefore not whether it can recreate yesterday's tax regime.
It is whether a modern alternative can accomplish the economic purpose that the old system once served without recreating its weaknesses.
That could mean incentives tied directly to measurable substance in Curaçao: employees, payroll, physical investment, exports, logistics activity, intellectual property development, regional headquarters functions or foreign-exchange earnings.
Such an approach would fundamentally differ from granting a low tax rate merely because income originates abroad.
The incentive would reward economic activity rather than legal location.
Curaçao Needs to Know What It Lost — and What It Can Build
Ultimately, the debate exposes a broader weakness in economic policymaking.
Compliance with international standards is important, particularly for a jurisdiction whose financial system and international business sector depend on access to global markets.
But compliance should not substitute for economic strategy.
Whenever Curaçao gives up an economic instrument because international standards require reform, government should simultaneously determine what economic function that instrument performed and how that function will be replaced.
If the Free Zone generated employment, trade, logistics and foreign exchange, eliminating an unsustainable tax structure did not eliminate Curaçao's need for those things.
The country still needs export earnings. It still needs foreign investment. It still needs internationally oriented companies. And it still needs ways to overcome the disadvantages created by its limited scale.
That is ultimately where the discussion about ring-fencing should lead.
The choice is not between fighting tax avoidance and protecting Curaçao's economy. Both objectives should be possible.
The more difficult question is whether international tax architecture sufficiently recognizes that a rule applied equally to economies of radically different sizes can produce very unequal outcomes.
For Curaçao, Aruba, Sint Maarten and similar small jurisdictions, that question deserves more than a tax-policy answer.
It deserves an economic one.
