Whatever happened to the thriving offshore sector of the Netherlands Antilles (Curacao)?

In a recent article in this column, I more or less compared the double assault on the Citizenship By Investment programs of some Eastern Caribbean countries by the EU and US to the demise of the buoyant offshore financial sector in the now defunct Netherlands Antilles. I promised to elaborate on the latter, so here goes.

The decline of the offshore financial sector in the former Netherlands Antilles—centered primarily in Curaçao—was not an overnight collapse, but a gradual unraveling that began in the mid-1980s and culminated in the early 2000s.

At its peak in the 1970s and early 1980s, Curaçao was one of the premier offshore financial hubs in the world. International corporations used Antillean financial subsidiaries to issue Eurobonds and funnel dividends with minimal withholding tax under favorable tax treaties.

When Did the Decline Begin?

It can be argued that the offshore financial sector in The Netherlands Antilles (Curacao) died a slow and painful death. The initial shock occurred between 1984  and 1987 when  the United States introduced fundamental changes to its tax code and the bilateral tax treaty with the Netherlands Antilles via The Kingdom of the Netherlands.

This was followed by a period of systemic phase-out which went from 1998 to 2002. During this period, international pressure from the OECD and the European Union forced the Netherlands Antilles to dismantle its so-called “ring-fenced” tax regime which offered super low tax rates exclusively to non-residents.

The whole process was formally concluded in 2019, almost a decade after the dissolution of the Netherlands Antilles. This was when the “grandfathering” provisions for legacy offshore companies officially expired, thereby ending the classic offshore era in Curacao.

Note that St. Maarten did not benefit substantially from this era, even though it formed part of The Netherlands Antilles until this became defunct in 2010.

Why and How Did It Happen?

The decline was driven by three main waves of geopolitical, legal, and regulatory changes.

The first wave was marked by changes to US tax laws and the termination of the bilateral tax treaty with the Netherlands Antilles.

During the 1970s, U.S. corporations routinely established finance subsidiaries in Curaçao to issue international bonds (Eurobonds). Under the 1955 U.S.–Netherlands Antilles Tax Treaty, these bonds avoided the standard 30% U.S. withholding tax on interest paid to foreign investors.

In 1984 the U.S. Congress repealed the 30% withholding tax on portfolio interest paid to foreign investors directly from the U.S. Overnight, American corporations no longer needed Curaçao subsidiaries as middleman conduits.

Then in 1987, citing widespread tax avoidance by non-U.S. residents using the "Antilles Loophole," the U.S. Treasury unilaterally terminated most provisions of the bilateral tax treaty. This effectively ended Curaçao’s lucrative role as a conduit for U.S. capital flows.

It would be naive to believe that the U.S. Treasury went ahead to unilaterally end most provisions of the bilateral tax treaty without the knowledge and acquiescence of the Kingdom of the Netherlands. After all, international treaties constitute a Kingdom affair, which means that the Dutch government is the only legal sovereign authority that can enter into international treaties on behalf of the territories under its jurisdiction.

Interestingly, the decade spanning the 1980s to the mid-1990s was the heyday of the offshore financial system in Europe. The Netherlands was raking in a windfall serving as the premier European "conduit" nation. Through its extensive network of bilateral tax treaties and tax exemptions (like the participation exemption), multinational corporations routed global profits through Dutch holdings to wipe out withholding taxes.

However, by the mid-1990s, the larger European economies (particularly France and Germany) faced severe budget deficits and high domestic tax burdens. They argued that smaller EU states and offshore dependencies were engaging in "harmful tax competition"—effectively poaching their tax bases. In response, the European Union launched an aggressive internal campaign parallel to the OECD's global crackdown, leading to the harmonization of tax regimes.

This was when the second wave started that eventually crushed the booming offshore sector in Curacao. The Organization for Economic Cooperation and Development (OECD) published its seminal report on Harmful Tax Competition in 1998.

The OECD and EU identified the Netherlands Antilles' practice of charging non-residents an ultra-low corporate tax rate (typically 2.4% to 3%) while taxing domestic companies at much higher rates (30–45%) as harmful tax competition.

Under serious threats of being blacklisted by international financial institutions, the Netherlands Antilles was forced to bring its tax laws into compliance with international (EU) standards.

The third and final wave put the nail in the coffin of the Netherlands Antilles offshore tax regime. This was a legislative measure, taken under pressure, that finally dismantled the offshore sector as we knew it.

To meet international demands, the Netherlands Antilles legislature overhauled its tax system by enacting the New Tax Regime (Nieuw Belastingstelsel or NBS) in 2001–2002:

The distinct separation between "offshore" (foreign) and "onshore" (local) companies was abolished.

A single, unified corporate tax rate was introduced across the board. While transitional rules allowed existing offshore entities to keep their low tax rates until 2019, no new offshore licenses were granted under the old rules.

Impact on Curaçao

The decline of the offshore sector had profound economic consequences for Curaçao and the central government of the Netherlands Antilles:

Fiscal Loss: In the early 1980s, offshore profit tax accounted for 30% to 40% of the total tax revenues for the island territory of Curaçao. By the late 1990s, this revenue stream had dwindled dramatically, plunging the island into persistent budget deficits and severe economic adjustments.

Adaptation & Evolution

Rather than disappearing entirely, Curaçao’s financial services sector transitioned away from mass tax avoidance toward higher-value, fully compliant services: It pivoted toward trust services, international private wealth management, and fund administration compliant with FATF (Financial Action Task Force) standards.

Economic Diversification: The island increasingly turned its economic focus toward tourism, maritime services, logistics, and renewable energy to fill the structural void left by the former offshore banking boom.

I believe the  Eastern Caribbean countries under pressure from both the US and the EU to fold up their Citizenship By Investment programs can learn a lesson or two from Curacao’s experience with its offshore financial sector. In my opinion, the CBI program is doomed to die, strangulated by the unyielding pressure from the US and the EU. It would be wise for the Caribbean countries to start seeking alternatives to replace it.
