Barbados and the Vatican City are two States whose sovereignty is fundamentally atypical. Barbados is a small Caribbean Island nation that formally severed its last institutional ties with the British Empire in 2021, but is structurally dependent on tourism, global financial markets, and climate decisions made by major powers.

The Vatican is the only theocratic state in the world with a population of about 800 people and a territory of 44 hectares, whose physical dependence on Italy has no precedent in international relations, while its "soft power" covers 1.3 billion Catholics. Both States embody the gap between legal independence and real opportunities, but the nature of this gap is diametrically different.

Barbados: postcolonial sovereignty in the face of climate and financial vulnerability

On November 30, 2021, Barbados declared a republic, removing Elizabeth II from the constitutional formula of statehood. It was a politically significant step, the first such act in the region in decades. However, it did not change the structure of the country's economic dependence. Barbados remained a member of the Commonwealth of Nations, retained British common law as the basis of the legal system, and continued to use the Barbados dollar, pegged to the US dollar at a fixed rate of 2:1 since 1975.

The symbolic break with the monarchy exposed the central paradox of postcolonial sovereignty: formal independence from the metropolis does not mean real autonomy in a world where financial flows, tourist markets and climate threats are controlled by mechanisms beyond the control of a small state.

The tourist trap: an economy without diversification

Barbados is one of the most expensive and attractive tourist destinations in the Caribbean. Tourism generates about 40-45% of the country's GDP and provides employment for a significant part of the active population. In 2020, the COVID-19 pandemic ruined the tourism sector by more than 75%, leading to an immediate crisis in public finances: debt rose to 157% of GDP at its peak. The country was forced to resort to an IMF program of about $290 million.

This episode clearly demonstrated that the sovereignty of a state whose economy depends on one sector for 40% and almost entirely on the decisions made by tourists in the UK, USA and Canada is conditional. Barbados cannot influence where British pensioners or American newlyweds go, but it is their choice that determines the island's state budget.

Attempts at diversification, the development of financial services (offshore sector), the digital economy, the Welcome Stamp program for "digital nomads," are yielding results, but they do not change the structural vulnerability. The offshore financial sector, in turn, depends on international tax standards, which Barbados does not form: the OECD and the G20 have repeatedly included the country in the "gray lists" of jurisdictions with insufficient tax control.

Climate sovereignty: a threat that cannot be stopped alone

Barbados is a low-lying island with a maximum height of about 340 meters. Rising sea levels, increased hurricanes, and changes in precipitation patterns are not abstract threats, but already documented phenomena affecting the coastline, agriculture, and tourism infrastructure.

The Prime Minister of Barbados, Mia Mottley, has become one of the most prominent international voices on the climate agenda: the Bridgetown Initiative, launched in 2022-2023, called for reform of the global financial architecture—primarily the IMF and the World Bank— to ensure climate finance for small island States. The program has received wide international attention, but its implementation remains limited.

Here, the paradox of sovereignty reaches its maximum severity: a state that contributes less than 0.01% of global co₂ emissions bears disproportionately high consequences of climate decisions made by the world's largest economies. Mottley has the right to vote on the COP, but not the right to veto in the national parliaments of China, the United States or India.

Regional integration: CARICOM as a limited sovereign instrument

Barbados is an active member of the CARICOM (Caribbean Community) and is part of the Caribbean Single Market and Economy (CSME). However, CARICOM remains a weak integration structure: the free movement of goods has only partially been implemented, and a unified foreign policy is still more a declaration than a practice. Barbados cannot compensate through regional integration for the leverage that small European states have through the EU.

Vatican City: Sovereignty as a spiritual extraterritoriality

On February 11, 1929, Mussolini and Cardinal Gasparri signed the Lateran Agreements, which created the Vatican City State. It was an act of mutual recognition: Italy was legitimized by the Holy See, and the Vatican received 44 hectares of sovereign territory in the center of Rome. This is the minimum sovereignty necessary for the Pope to act as an independent international authority, and not as a subject of the Italian state.

The physical parameters of this sovereignty border on the absurd: 44 hectares, about 800 inhabitants with citizenship (mostly members of the Swiss Guard and senior clerics), no natural resources, no agriculture, no industry, no access to the sea. The Vatican is the only state in the world that is physically impossible to leave without entering the territory of another state. The entire infrastructure, electricity, water, sewerage, telephone networks, Internet, is tied to Italian systems.

Dependence on Italy: infrastructure as sovereignty

The Vatican's relations with Italy are governed by a number of agreements, of which the revised Concordat of 1984 is the most important. De facto, the cooperation is much deeper: the Italian Carabinieri provides security in St. Peter's Square (legally Italian territory). Italian fire services are responding to incidents in the Vatican. The Italian judicial apparatus, not the Vatican one, conducts a number of cases involving citizens who have committed crimes on Vatican territory.

In 2012-2013, the Italian authorities suspended the operation of ATMs in the Vatican after the Bank of Italy revoked the license of the intermediary bank through which the Vatican terminals operated. The state was left without cash payments, literally as a result of the administrative decision of the Italian regulator. This event clearly showed that the Vatican's financial infrastructure is built into the Italian system, rather than being autonomous. Financial model: IOR, donations and Peter's Pence

The Vatican is funded from several sources. Peter’s Pence, the annual donations of Catholics from all over the world, generates an important but unstable income stream: about 50-80 million euros per year, which is significantly less than is often assumed.

The Vatican museums generate about 100 million euros per year (with an influx of 6-7 million visitors before the pandemic). The Institute of Religious Affairs (IOR, the “Vatican Bank”) manages assets in the interests of religious organizations — its real balance sheet has long been opaque, which has given rise to scandals: the Calvi banker case (1982), the MONEYVAL investigations, and the reforms under Francis.

The Vatican does not pay Italian taxes on real estate in Rome, this has long been questioned by the European Commission as a hidden state aid. It is estimated that the Catholic Church owns hundreds of billions of euros worth of real estate in Italy, much of which is tax-exempt through various structures. This is not Vatican sovereignty in its purest form, it demonstrates that the line between the state and the institution of the Church is fundamentally blurred.

Soft power as the only real resource

The Vatican maintains diplomatic relations with 183 states, more than many major countries. Its permanent observer status at the United Nations allows the Holy See to participate in international negotiations on a wide range of issues, from bioethics to climate, from peace in the Middle East to refugee rights.

The role of Pope John Paul II in the collapse of the Soviet bloc (supporting Solidarity in Poland), the Vatican’s mediation in normalizing Cuban-American relations under President Obama in 2014, and Pope Francis’ meetings with the leaders of Russia and Ukraine are all examples of influence that is fundamentally not measured by territory or GDP. This is the "sovereignty of legitimacy": an authority based not on coercion, but on moral recognition.

The cultural sovereignty of the Vatican (91.7) is the highest among all states in the research series. This reflects the unique nature of the Holy See: its cultural influence is incomparable with the physical parameters of the state and surpasses most major powers in scale.

The military sovereignty of the Vatican (12.8) is one of the lowest indicators. The Swiss Guard (about 135 people) is a symbolic and ceremonial corps, not a real military force. The Vatican's security is provided by Italian structures.

The economic sovereignty of Barbados (52.1) reflects tourism and offshore dependence, limited diversification and vulnerability to external shocks (pandemics, climate disasters, international tax standards).

The political sovereignty of Barbados (68.4) is relatively high for a small island nation, which is explained by a stable parliamentary system, an independent judicial branch and an active international position (the Bridgetown Initiative).

A common paradox: the two poles of intangible sovereignty

Barbados and the Vatican City demonstrate two extreme cases of what can be called intangible sovereignty, independence based not on traditional resources (territory, army, industry), but on symbolic, institutional or regulatory grounds.

Barbados builds its sovereignty on diplomatic activity: a country that makes a negligible contribution to global emissions, claims to be a moral authority in climate negotiations. This is sovereignty through normative leadership, a strategy that works as long as major players are willing to provide small states with a voice, but not a veto.

The Vatican builds sovereignty on transcendent legitimacy: a state that cannot be left without entering another country influences the politics of dozens of states through the conscience of their citizens. This is sovereignty through identity, a unique model that has no analogues in the system of international relations.

Both States confirm the thesis that in the 21st century sovereignty is less and less measured in square kilometers and more and more in the ability to shape the agenda regardless of its own physical scale.
