The Permanent Scar: How a Wider War With Iran Could Inflict Lasting Damage on the Global Economy

The head of the International Monetary Fund doesn’t typically traffic in alarm. Kristalina Georgieva’s job requires a kind of institutional calm — measured language, diplomatic hedging, careful optimism about growth forecasts even when the numbers look grim. So when she warns that a military conflict involving Iran could “permanently scar” the global economy, it’s the kind of statement that cuts through the noise.

Her remarks, delivered during a press conference ahead of the IMF’s spring meetings, landed with particular force given the current geopolitical climate. As The Guardian reported, Georgieva made clear that the consequences of a wider Middle Eastern conflict would extend far beyond the region itself, rippling through energy markets, trade corridors, and financial systems in ways that could prove irreversible. Not a temporary shock. A permanent one.

That distinction matters enormously.

Economists draw a sharp line between cyclical downturns — recessions that economies eventually recover from — and structural damage that reshapes productive capacity for years or decades. Georgieva was explicitly invoking the latter. The IMF’s own research has shown that wars in economically significant regions tend to destroy not just physical capital but institutional trust, trade relationships, and investment pipelines that took generations to build. Iran sits at the crossroads of several such networks, and its role as a major oil producer makes any conflict involving it a direct threat to the commodity markets that underpin global growth.

The timing of Georgieva’s warning is no accident. Tensions between the United States and Iran have been escalating for months, with Washington tightening sanctions enforcement and Tehran accelerating its nuclear enrichment program. Military posturing in the Persian Gulf has intensified. And while diplomatic channels remain technically open, the space for negotiation has been shrinking steadily since the collapse of the 2015 nuclear deal.

Oil markets have already priced in some of this risk. Brent crude has been trading above $90 a barrel for weeks, and options markets show elevated demand for upside protection — traders betting on the possibility of a spike well above $100. But Georgieva’s comments suggest the IMF believes markets may still be underestimating the tail risk. A full-scale conflict could take a significant share of global oil supply offline almost overnight, given Iran’s production of roughly 3.2 million barrels per day and the vulnerability of shipping through the Strait of Hormuz, through which approximately 20% of the world’s oil passes daily.

That’s the immediate shock. The scarring Georgieva described is something different and far more insidious.

Consider what happened after Russia’s invasion of Ukraine in 2022. Energy markets spiked, yes, but the deeper damage came from the fracturing of trade relationships, the weaponization of financial infrastructure, and the acceleration of economic decoupling between major powers. Europe spent hundreds of billions of euros building new energy infrastructure to replace Russian gas — money that could have gone to productive investment elsewhere. Supply chains were rerouted at enormous cost. Trust between trading partners eroded in ways that haven’t been rebuilt. A conflict involving Iran would trigger a similar but potentially larger set of disruptions, given the centrality of the Persian Gulf to global energy and shipping infrastructure.

The IMF’s World Economic Outlook, which is set to be released in the coming days, is expected to downgrade growth forecasts for several regions already dealing with the aftereffects of trade tensions and tighter monetary policy. Adding a major military conflict to that picture would, in Georgieva’s framing, push the global economy into territory from which full recovery becomes genuinely uncertain. She pointed specifically to developing economies that are heavily dependent on energy imports — countries in Sub-Saharan Africa, South Asia, and parts of Latin America that are already struggling with debt burdens and food insecurity. For these nations, a sustained oil price shock wouldn’t just slow growth. It could reverse years of development progress.

There’s a financial dimension too. Iran’s connections to the global banking system are limited by sanctions, but a wider conflict would almost certainly draw in other regional actors — Saudi Arabia, the UAE, Iraq, possibly Israel — whose financial systems are deeply integrated with Western markets. Insurance costs for shipping in the Persian Gulf would skyrocket. Letters of credit for trade in the region would become harder to obtain. And the broader risk-off sentiment in financial markets could trigger capital flight from emerging economies at precisely the moment they can least afford it.

Central banks would face an impossible dilemma. An oil shock is stagflationary by nature — it pushes prices up while dragging output down. The Federal Reserve, the European Central Bank, and their counterparts in developing countries would have to choose between fighting inflation and supporting growth, with no good option available. The Fed’s experience in 2022 and 2023, when it raised rates aggressively to combat inflation partly driven by energy costs, offers a preview of how painful that trade-off can be. But a conflict-driven spike would be even harder to manage because it wouldn’t respond to monetary tightening the way demand-driven inflation does.

Georgieva’s use of the word “permanently” was deliberate and, by IMF standards, extraordinary. The Fund has historically been cautious about declaring any economic damage irreversible, preferring to frame even severe crises as challenges that can be overcome with the right policy mix. That she chose to break from that convention signals a genuine level of institutional concern about the trajectory of events in the Middle East.

And she’s not alone in sounding the alarm. The World Bank has separately flagged the risks of a broader Middle Eastern conflict to global food security, given the region’s role in fertilizer production and grain shipping routes. The Bank for International Settlements has warned about the potential for financial contagion if conflict disrupts the dollar-denominated oil trade. Even private sector analysts at firms like Goldman Sachs and JPMorgan have been revising their risk scenarios upward, with some models suggesting Brent could hit $150 a barrel in a worst-case scenario involving a prolonged closure of the Strait of Hormuz.

The political calculus is no less fraught. Washington’s approach to Iran has been shaped by competing priorities — nonproliferation concerns, energy security, alliance management in the Gulf, and domestic political pressures that make any appearance of weakness toward Tehran politically toxic. The Biden administration’s successor has taken a harder line, and the appetite for diplomacy in Congress is minimal. On the Iranian side, domestic politics have also hardened, with reformist voices marginalized and the Islamic Revolutionary Guard Corps exercising increasing influence over foreign policy decisions.

None of this makes war inevitable. But it makes the conditions for miscalculation dangerously ripe.

Georgieva urged world leaders to “step back from the brink” and pursue diplomatic solutions, according to The Guardian’s reporting. She emphasized that the IMF stands ready to provide financial support to countries affected by any escalation, but acknowledged that the Fund’s resources would be stretched thin in a scenario involving a major regional war on top of existing global economic challenges. The IMF’s lending capacity, while substantial, was already under pressure from commitments to Ukraine, Pakistan, Argentina, and dozens of other countries that have sought assistance in recent years.

What makes this moment particularly precarious is the absence of the kind of global coordination that helped manage previous crises. During the 2008 financial crisis, the G20 came together with remarkable speed to coordinate fiscal stimulus and financial regulation. During the COVID-19 pandemic, central banks acted in concert to prevent a total collapse of financial markets. But the geopolitical fragmentation of recent years — the U.S.-China rivalry, the fallout from the Ukraine war, growing skepticism toward multilateral institutions — has eroded the capacity for that kind of collective action. If a conflict with Iran does erupt, the global economy would face it without the institutional shock absorbers that softened previous blows.

So what would permanent scarring actually look like in practice? The IMF’s own research offers some clues. A 2023 working paper found that countries affected by major conflicts experienced GDP losses of 10% to 30% over a decade, with the damage concentrated in trade openness, foreign direct investment, and human capital. For the global economy, the scarring would likely manifest as a sustained increase in energy costs, a further acceleration of trade fragmentation as countries scramble to secure supply chains, and a lasting increase in risk premiums across financial markets. Growth potential — the speed at which economies can expand without generating inflation — would be permanently reduced.

That’s the world Georgieva is warning about. Not a recession that ends in a few quarters. A structural downshift in what the global economy is capable of producing.

For policymakers, the implications are stark. Every dollar spent on military escalation is a dollar not spent on the energy transition, infrastructure, education, or the kinds of investments that raise long-term growth potential. Every trade route disrupted is a relationship that may never fully recover. Every month of elevated uncertainty is a month in which businesses defer investment decisions, compounding the damage over time.

The markets, for now, are watching and waiting. Volatility indices have ticked up but haven’t spiked to crisis levels. Credit spreads in emerging markets have widened modestly. Gold has been climbing steadily, a classic hedge against geopolitical risk. But the relative calm in financial markets shouldn’t be mistaken for complacency — or for an accurate assessment of the risks. Markets are notoriously bad at pricing low-probability, high-impact events until they actually happen. By then, it’s too late.

Georgieva’s warning was, at its core, an attempt to change that calculus. To make the costs of conflict vivid enough that the people with the power to prevent it might actually do so. Whether anyone is listening is another question entirely.
