The US military gamble, encouraged by Israel’s longstanding campaign against Iran and sold with promises of decisive victory, has unleashed an economic shock whose costs are being transferred to households, businesses and developing economies.

The Center for Research on Energy and Clean Air (CREA) estimates that consumers worldwide have paid an additional $468 billion for gasoline and diesel since the US and Israeli war on Iran began on February 28.

Of that staggering sum, the United States accounts for $160 billion, approximately one-third of the global increase, despite being the world's largest oil producer.

Americans have incurred an additional $471 per person, nearly eight times the estimated global average of $60, while Chinese consumers have absorbed another $54 billion nationally and Canadians $17 billion.

The figures, covering 169 countries, expose the extraordinary economic repercussions of an unprovoked military aggression whose consequences have travelled far beyond Iran's borders.

The figures represent additional expenditure on everyday transportation fuels, before accounting for the wider economic consequences transmitted through electricity, freight, aviation, manufacturing, agriculture and international trade.

CREA's October 26 assessment provides a revealing starting point for understanding how Washington's decision to wage war has generated an economic shock extending across continents.

The central contradiction is that the country possessing the world's largest oil-producing industry has become the biggest national payer of an energy shock associated with its own military intervention.

Domestic oil production has offered American households little protection against internationally determined prices, while businesses and consumers throughout Europe, Asia and developing economies have confronted comparable pressures.

The economic catastrophe cannot be separated from Washington's imperial ambitions and belligerent calculations, which propelled the United States headfirst into an unnecessary confrontation with Iran.

For years, Israeli prime minister Benjamin Netanyahu has relentlessly pursued military confrontation, portraying Iran as an existential threat through repeated nuclear fabrications.

Netanyahu exploited Trump's appetite for historic victories, invoking the attack on Iran as a mission to save Jews from an existential threat, thus lulling the mercurial US president into a messianic vision of conquest, historic glory and American domination.

The promise of enormous economic and geopolitical dividends from conquering a country possessing some of the world's largest combined oil and gas reserves struck a chord with a president whose recent success in invading Venezuela reinforced his appetite for easy victories, resource control and the spoils of regime change.

Those promises, however, gave way to a destructive war whose economic consequences are being borne by American taxpayers, European households and economies across the developing world.

The Strait of Hormuz became the principal transmission mechanism through which the war destabilized international markets, demonstrating the extraordinary vulnerability of global commerce to disruptions involving strategically important maritime corridors.

Approximately one-fifth of internationally consumed petroleum normally passes through this narrow waterway, alongside substantial liquefied natural gas shipments and internationally traded fertilizers.

The energy shock has extended beyond crude petroleum because US attacks against regional infrastructure and restrictions on maritime transportation have simultaneously affected refining capacity, natural-gas supplies and petroleum-product availability.

According to CREA's October assessment, diesel prices have increased in 149 countries, while gasoline prices have risen in 148, demonstrating the extraordinary geographical reach of the disruption.

Refinery damage and interrupted exports have compounded the initial crude-price shock, leaving transportation companies, agricultural producers, manufacturers and ordinary consumers confronting substantially higher operating expenses.

A separate CREA assessment published in August estimated that fossil-fuel importers had incurred approximately $330 billion in additional expenditure on seaborne crude oil, petroleum products and liquefied natural gas during the preceding six months.

These import costs measure a different economic category from the $468 billion gasoline and diesel expenditure estimate, and must not be added together.

Nevertheless, both assessments demonstrate how the war has generated financial consequences extending well beyond the direct costs of military operations.

The economic consequences are increasingly visible through demonstrations and strikes across America and Europe, where households confront higher living expenses alongside expanding military appropriations.

Europe has been rocked by massive protests, marked by violent clashes between demonstrators and police, as mounting living costs, soaring energy prices and opposition to military spending fuel growing public anger over the economic consequences of the war.

The financial consequences become considerably more revealing when direct expenditure is considered alongside the broader destruction of economic output projected by independent researchers.

CREA's estimated $468 billion additional global gasoline and diesel expenditure, combined with the Pentagon's $47.1 billion military expenditure estimate through October 16, already represents approximately $515.1 billion.

This calculation excludes numerous additional costs, including disrupted production, infrastructure destruction, lost trade, insurance increases and deteriorating international investment conditions.

There is, however, a much stronger figure for the conclusion. The Institute for Economics and Peace, through its Global Peace Index 2026 analysis, estimates that the war could cost the world $1.3 trillion in lost GDP during 2026 under its extended-war scenario.

If the war resumes and the Strait remains closed for six months or longer, its estimate rises to approximately $3.5 trillion.

These projections reveal the extraordinary scale of the economic destruction potentially unleashed by a military aggression whose consequences extend across international production, trade, investment and consumption.

Washington's repeated presentation of the war through occasional announcements of $40 billion or $50 billion in military expenditure consequently obscures the much larger international economic burden.

The promised quick victory and extraordinary dividends have instead produced hundreds of billions in additional expenditure and a projected trillion-dollar reduction in global economic output.

The fundamental injustice of this economic transmission is that the people paying the highest social and financial costs are overwhelmingly those who neither authorized the intervention nor possessed any influence over its strategic objectives.

American taxpayers finance military aggressions, European households absorb energy shocks, developing countries confront deteriorating import bills, and farmers worldwide face increasing uncertainty over agricultural production.

The $468 billion figure, more than an alarming measurement of rising fuel expenditure, is an indictment of the economic assumptions underlying military intervention as an instrument of geopolitical power.

The ultimate cost will not be measured exclusively in dollars spent on fuel, missiles and military operations, but also in livelihoods lost, investment postponed, public services constrained and economic opportunities sacrificed across generations.
