Iran, oil, and the fragility of emerging markets

Whenever there is tension in the Middle East, oil prices tend to react before diplomats and institutions do. Markets move on fear, rather than confirmed disruption. Whenever there's a resurfacing of instability surrounding the nation of Iran, the consequences extend far beyond just their territory. The real question is not only about what happens in Iran, but it also lies on the uncertainty of emerging markets when oil becomes volatile once again.

To this day, Iran remains one of the world’s most important oil producers, located near the Strait of Hormuz - a narrow passage through which a significant share of global oil supply travels. Just the possibility of supply disruption is enough to send prices upward.

The course of history has shown that markets don’t wait for shortages to happen but immediately adapt the price to risk. One could say that oil isn’t reacting to reality but to the uncertainty around it. For emerging markets, that uncertainty can be costly. Many developing economies are heavily dependent on energy imports.

Countries such as India, Turkey, amongst many other Southeast Asian nations rely on stable oil prices to keep inflation under control and growth steadily increasing. When oil prices rise, so do import bills - probably even quicker. Governments are then forced to face difficult decisions: allow domestic fuel prices to increase (fueling inflation), or choose to subsidize energy, consequently widening fiscal deficits. Evidently, neither option is particularly attractive.

Similarly, higher oil prices tend to ripple through the entire economy: transport costs rise, food prices increase, manufacturing becomes more expensive too. Once triggered, inflation is rarely isolated to just one sector. Central banks in emerging markets often respond by tightening monetary policy in order to prevent the depreciation of their currency and capital from escaping. However, higher interest rates can slow economic growth down, creating a delicate balancing act between stability and expansion.

Furthermore, oil shocks do not affect all emerging markets equally. For some countries, volatility presents an opportunity, rather than being a threat. Some oil exporting nations such as Saudi Arabia, Nigeria, and even Brazil can benefit from rising crude prices, as export revenues increase and fiscal positions become stronger. For them, geopolitical instability might be their chance to temporarily boost national income. The difference between oil importers and exporters reveals how uneven the consequences of global shocks can be, just within the emerging world.

Going past inflation, oil volatility also influences investor sentiment. When geopolitical risk intensifies, global markets tend to shift into what is typically referred to as a “risk-off” mode. Investors choose to move capital away from the volatile emerging markets and towards what is perceived as a safe haven (which almost always goes back to US assets). The American dollar tends to get even stronger in periods like this, which puts additional pressure on emerging market currencies to perform. For countries that import oil, this creates a double burden: higher energy costs combined with weaker exchange rates.

Iran becomes more than a regional actor in a context like this - it turns into an example of the broader fragility that exists in the global economic system. Even without any direct military escalation, the mere presence of uncertainty surrounding its geopolitical position can trigger reactions in markets for commodities, currencies and equities all around the world. Modern finance has become so interconnected that no economy remains isolated from these shocks, even though some may feel the hits are stronger than others.

Still, it's important to distinguish between temporary volatility and long-term damage. Oil prices spikes, if driven purely by fear, may eventually stabilize if supply routes remain intact and diplomatic efforts ease tensions. Over the years, emerging markets have been able to build stronger foreign exchange reserves and central banks prepared precisely to withstand such external shocks. If we compare it to previous decades, many nations are now better equipped to absorb short-term turbulence.

It has to be kept in mind that resilience does not eliminate vulnerability. If instability in the Middle East is persistent, it could sustain elevated energy prices, keeping inflationary pressures alive for longer than expected. For economies that are already navigating rough fiscal conditions or still struggling through post-pandemic recovery, this would complicate growth prospects. Investors, wary of prolonged uncertainty, may demand higher risk premiums before committing capital to a nation.

What is most shocking about the current situation is how quickly global markets respond to headlines. Oil futures react within minutes. Emerging market currencies fluctuate within hours, even less. In many ways, financial markets have become early-warning systems for geopolitical tension. Whether or not any actual disruptions occur, the economic impact begins long before any barrels of oil are physically removed from circulation.

The broader issue, therefore, extends beyond just Iran alone. It reflects how dependent emerging economies remain on external stability - on shipping routes, commodity flows, and investor confidence. Growth strategies built on industrial expansion and consumer demand can be derailed by forces entirely outside of one country’s control.

So, will this wave of uncertainty translate into a lasting setback for emerging markets? The answer mostly depends on duration. If tensions ease and oil prices retreat, the shock may prove manageable. If instability lingers, inflation and tighter financial conditions could slow growth across several developing economies.

Emerging markets have demonstrated resilience in the face of global crises before. Yet episodes like this serve as a reminder: in an interconnected world, economic stability is often shaped as much by geopolitics as by domestic policy. When oil moves before diplomacy, the ripple effects are felt far beyond the Gulf - and emerging markets are usually the first to absorb the shock.
