Persian Gulf: where oil enters the world through a narrow gate

This article is part of In conversation about sustainable finance & emission reduction systems, a new series by Diego Balverde. You're reading volume six of the Logbook of the BalGreen: Sailing the Seven Seas series. Here is volume five

Part of Diego Balverde's upcoming book on how wars, gas, electricity and infrastructure are redrawing the global economy.

Prologue

The BalGreen Net Zero Explorer moves toward the Persian Gulf with a feeling unlike any of the previous stages. The Adriatic showed us that restoring nature can become financial flow. The Aegean taught us that islands can stop importing vulnerability if they monetise efficiency. The Black Sea revealed that grain sails with fear, insurance and corridors. The Red Sea proved that a route under threat can make homes, factories and governments more expensive. But the Persian Gulf takes that logic to its most concentrated point: here, it is not only energy that moves. Global prices, inflation, fiscal power, national security, debt, fertilisers, electricity, transport, petrochemicals, logistics and political stability move with it.

Marco Silva works over charts where the sea looks narrow compared with the scale of what it represents. The Strait of Hormuz connects the Persian Gulf with the Gulf of Oman and the open ocean, but in economic terms it connects producers, refiners, Asian markets, central banks, shipping companies, insurers and consumers. A narrow point can move an entire economy. That is the silent violence of chokepoints. They do not need to close completely to affect prices. It is enough for risk to rise, for premiums to adjust, for a shipowner to hesitate, for an insurer to change conditions, or for a buyer to bring inventory forward for the cost to travel. In 2024, oil flows through the Strait of Hormuz averaged around 20 million barrels per day, equivalent to about 20% of global petroleum liquids consumption, and in the first quarter of 2025 those flows remained relatively stable compared with 2024.

Ahmed El-Sayed keeps the Explorer in high energy vigilance mode. The vessel carries its 720 kilograms of compressed hydrogen at 350 bar, but consumption moves between 24 and 30 kilograms per day during this stage because of intensive communications, radar, sensors, cooling, traffic monitoring, security protocols and system redundancy. The heat is denser, drier, more technical. It is felt not only on the skin. It is felt in batteries, pumps, ventilation, the laboratory and auxiliary consumption. The Persian Gulf forces us to understand a truth Ahmed repeats while watching the screens: when risk rises, everything consumes more. More energy, more capital, more insurance, more surveillance, more inventory, more patience and more money.

Helena Kovac prepares the Gulf environmental protocol. Here, the sea is crossed by hydrocarbons, high salinity, extreme heat, tanker traffic, offshore infrastructure, desalination, industrial ports and fragile ecosystems. The Gulf is not a liquid desert. It is a system of high environmental and economic pressure. As the Explorer advances, Sofía Rinaldi films the contrast between the hard blue of the water, the heat on the horizon and the movements of vessels that appear slow but carry global decisions. Jonas Müller checks the deck with a different precision. In these waters, a small failure can multiply through traffic, heat, security and response distance.

Before approaching Dubai and the Gulf port axis, Diego Balverde writes in the logbook: "Hormuz proves that the modern world does not depend only on producing energy. It depends on that energy being able to leave without fear. A trapped barrel does not light a city. Delayed LNG does not heat a factory. A nervous route does not sell oil. It sells risk."

The Persian Gulf is also a gas story. In 2024, around 20% of global LNG trade transited Hormuz, primarily from Qatar, with approximately 9.3 Bcf/d exported by Qatar and 0.7 Bcf/d by the United Arab Emirates through the strait. Around 20 mb/d, close to 25% of global seaborne oil trade, transits Hormuz, and approximately 93% of Qatar's LNG exports and 96% of the UAE's LNG exports pass through the strait, representing around 19% of global LNG trade. These figures are not isolated energy data. They are a warning: a strip of water can enter Asia's electricity bill, the price of fertiliser, European transport costs and the monetary policy of countries with no coastline in the Gulf.

Dubai, Fujairah and Hormuz – where energy becomes financial risk

The stop is articulated between Dubai, Fujairah and the Hormuz corridor. Dubai represents trade, services, finance, logistics and global narrative. Fujairah represents something more specific: the ability to operate outside the strait, store, supply, bunker, connect pipelines and reduce dependence on the bottleneck. Hormuz represents the critical point, the gate where the world remembers that oil and gas are not only commodities. They are physical flows that need routes, insurance, terminals, escorts, data and trust.

The Explorer's arrival brings together port authorities, energy operators, traders, maritime insurers, banks, terminal technicians, LNG specialists, economic media and chamber representatives. No one asks whether the vessel's hydrogen system is interesting. They ask how much a Gulf network can save if it reduces tanker waiting time, optimises bunkering, improves risk data, electrifies port operations, cuts auxiliary consumption, digitalises documents and creates evidence acceptable to banks and insurers. The chapter is no longer about energy as abundance. It is about energy as secure outlet.

In the main room, the name of the plan appears: Persian Gulf Energy Security Efficiency System, BalGreen Ports Hormuz Risk Value Architecture. Diego takes the floor with an imperative tone. "We are not here to ask for money to protect oil. We are here to show how much money the global energy system loses when energy leaves with uncertainty. Every tanker that waits, every policy that rises, every terminal that consumes more, every route that becomes tense, every cargo that is delayed and every buyer that brings inventory forward turns physical energy into financial risk. The Gulf does not need another security promise. It needs a system that measures friction, reduces exposure, organises data, issues bonds against savings and turns energy resilience into flow."

Lucas Andrade projects the financial model. The initial network works across 7 strategic nodes: Dubai, Jebel Ali, Fujairah, Abu Dhabi, Ras Laffan, Dammam and a digital Hormuz monitoring node. The logic is not to replace geopolitics or naval security. The logic is to reduce the economic cost of operating under concentrated risk. The fixed objective is to capture €118 million per year in operating, energy and financial savings. This flow consists of €34 million from reduced waiting time, unproductive anchorage and port-window coordination, €26 million from lower auxiliary consumption by tankers, terminals and bunkering operations, €18 million from energy efficiency in terminals, cold chain, pumping, lighting and equipment, €15 million from reduced documentary errors, cargo traceability and digitalisation of operating contracts, €13 million from improved risk profiles through verifiable data and audited protocols, and €12 million from inventory optimisation, buyer coordination and lower immobilised capital.

Hormuz Energy Security Bond – the system that turns a bottleneck into financeable flow

The Persian Gulf Energy Security Efficiency System begins from a simple and hard premise: the Gulf does not lose value because of a lack of energy, but because of the friction that appears when that energy must pass through a narrow gate under risk. BalGreen Ports enters to measure idle time, congestion, auxiliary consumption, terminal efficiency, emissions, tanker waiting time, port behaviour, documentary risk and coordination costs. DOIX.IO functions as the system's digital brain, recording operational data, MRV, avoided emissions, consumption, cargo traceability, risk dashboards and node performance. Incorporates the verifiable climate reduction layer derived from lower waiting time, reduced auxiliary consumption, energy efficiency and operating optimisation. Balanz Capital organises the flow as a financeable asset. Société Générale represents European structured banking and connection with sustainable bonds. Ashmore Group and CPP Investments appear as references of institutional capital capable of understanding critical infrastructure, debt, energy, risk and long-term scale. Earthshot Prize adds the reputational dimension of climate innovation, because reducing friction at the most sensitive energy point on the planet is not only efficiency. It is global stability.

The first issuance is the Hormuz Energy Security Bond, for €700 million, backed by the network's €118 million per year in operating and financial savings. The bond is not supported by abstract political confidence. It is supported by shorter waiting times, lower auxiliary consumption, energy efficiency, digital documentation, data acceptable to insurers, verified emissions reduction and operating coordination. The second phase scales to €1.4 billion issued once the network demonstrates two years of certified savings, incorporates more terminals, integrates LNG and crude operators, and consolidates DOIX.IO dashboards accepted by banks, insurers and buyers. The rule is strict: first friction is measured; then exposure is reduced; then savings are captured; later impact is verified; finally, bonds are issued against results.

The climate layer sets an initial reduction of 175,000 tonnes of CO₂ equivalent per year through lower tanker waiting time, lower auxiliary consumption, port energy efficiency, bunkering optimisation, reduced unproductive movement and partial electrification of operations. At a conservative price of €25 per tonne, this generates €4.375 million per year in verifiable climate value. When the system matures and reaches 350,000 verified tonnes, climate value scales to €8.75 million per year. Lucas explains it before operators and banks: "Carbon does not replace energy savings. It certifies them, makes them visible and turns them into an additional value layer. The base is the €118 million in efficiency. The climate credit increases liquidity and strengthens the financial narrative."

BalGreen's return is fixed with clear figures. On a network generating €118 million per year in operating savings and €4.375 million in initial climate value, BalGreen captures 6% per year for system architecture, MRV, technical coordination, financial structuring, data administration, operator relations, protocol design and operating success fees. That represents €7.34 million in recurring annual revenue in the initial phase. In the €700 million Hormuz Energy Security Bond issuance, BalGreen captures a 3.5% structuring fee, equivalent to €24.5 million at closing. In the second phase of €1.4 billion issued, the accumulated fee reaches €49 million, in addition to recurring revenues from monitoring, verification, data updates, climate asset administration, energy coordination and replication of the model across other chokepoints.

Diego intervenes again and connects the system to the real world. "A waiting barrel is not only delayed oil. It is more expensive transport, more expensive fertiliser, more expensive electricity, more expensive food and central banks watching imported inflation. LNG that does not leave on time is not only delayed gas. It is industry recalculating, contracts under pressure, shipping companies adjusting, insurers raising prices and countries searching for alternatives. The Persian Gulf does not need to prove that it has energy. It needs to prove that it can turn reliable outlet into measurable financial value."

Ahmed explains that the Explorer functions as a miniature of the system. Stored energy is not valuable simply because it is stored, but because it gives decision capacity when wind drops, the route becomes complicated or safety requires backup. Gulf energy works the same way. Reserves without reliable routes lose marginal power. Helena presents water samples and recalls that the Gulf also faces thermal stress, salinity, industrial pressure, heavy traffic and sensitive ecosystems. Sofía interviews operators who speak about tankers, bunkering, LNG, insurance, inventories and exit windows. Jonas watches the port movement and summarises: "Everyone looks at the barrel here. But the margin is in the waiting."

During dinner, the menu combines Gulf fish, spiced rice, dates, legumes, fruit, cold water, Arabic coffee and tea. Diego maintains his discipline and chooses fruit, legumes and water. The conversation with operators and technicians is not ceremonial. They ask about data, bank acceptance, whether DOIX.IO can build operational evidence, can register verifiable reductions, whether Balanz Capital can organise flows, and whether an issuance such as the Hormuz Energy Security Bond can find demand. Lucas answers with the logic of the entire saga: the market does not finance beauty; it finances measurable flows. If the system reduces loss, the bond stops being a promise and becomes an instrument.

At night, the Explorer remains moored while port activity continues. White lights, heat, tankers, tugboats, screens, radio voices and a sense of invisible tension dominate the quay. Diego writes in the logbook: "The Persian Gulf proves that energy is not sold only by existing. It is sold when it can exit, be measured, insured and financed. Hormuz is not a gate. It is a price."

Analysis – the chokepoint as a global balance sheet

The Persian Gulf reveals a truth the world often remembers too late: producing energy is not enough. Real value appears when that energy can exit with confidence, under insurable conditions, through functional routes, with acceptable data and controlled financial costs. A chokepoint does not make the world more expensive only when it closes. It makes the world more expensive when it introduces doubt. Doubt raises insurance, brings inventories forward, changes contracts, alters refineries, moves currencies, affects fertilisers, pressures transport and forces governments to rethink energy security.

The Persian Gulf Energy Security Efficiency System organises that reality. It does not promise to control geopolitics or eliminate military tension. It promises to reduce the economic part of friction that can be measured and corrected. If a tanker waits less, if a terminal consumes less, if a document is digitalised, if an insurer receives better data, if a port reduces emissions, if a cargo improves traceability, and if the system groups those results into flows, then the chokepoint stops being only a risk and begins to behave like financeable infrastructure.

The importance of the model goes beyond the Gulf. It can be applied to Hormuz, Suez, Bab el Mandeb, Panama, Malacca or any point where world trade depends on a narrow route. The methodology is the same: measure friction, reduce exposure, capture savings, verify impact and issue bonds against results. In a more unstable world, energy security cannot depend only on reserves. It must also depend on data, efficiency, redundancy and structured finance.

Conclusion – the Persian Gulf as a financeable energy security system

The Persian Gulf gives us a sixth optimistic answer, even though it comes from the most sensitive point in global energy. The Adriatic proved that restoring nature can become financial infrastructure. The Aegean proved that an island can finance itself through its own efficiency. The Black Sea proved that food security can be structured as a financeable corridor. The Red Sea proved that a route under threat can reduce the economic cost of fear. The Caspian proved that an energy region gains power when it improves its outlet. The Persian Gulf proves that even the most delicate chokepoint on the planet can transform part of its risk into financeable flow if it measures, coordinates and issues against savings.

The solutions exist and can already be organised. BalGreen Ports, DOIX.IO, Balanz Capital, Société Générale, Ashmore Group, CPP Investments and Earthshot Prize represent layers of the same architecture: port, data, verification, market, banking, institutional capital, reputation and innovation. If a Gulf network can capture €118 million in annual savings, issue €700 million in bonds backed by results and reduce 175,000 tonnes of CO₂ per year, then the world can stop treating chokepoints only as threats and start treating them as financeable resilience systems.

As the BalGreen Net Zero Explorer rests before the Gulf lights and tankers continue moving toward Hormuz, we understand that this chapter is not only about oil or gas. It is about price, trust and outlet. It is about how a narrow point can pressure homes, industries, currencies and governments. But it is also about an opportunity: turning efficiency, data and coordination into economic security. The world cannot widen Hormuz. But it can reduce the cost of depending on it.
