How the war between Israel and Iran could reshape the global economy.

War between Israel and Iran: Global fallout, Caribbean impact, and how to prepare

As tensions rise in the Middle East, the possibility of a full-scale war between Israel and Iran is no longer unthinkable. What might begin as air strikes or cyberattacks could escalate into a broader regional war, drawing in global powers and triggering wide-reaching consequences. This article examines how such a conflict would affect the world, with a focus on the Caribbean and Trinidad and Tobago’s economy.

It also outlines critical steps individuals can take to prepare for the financial and supply disruptions that would likely follow. Understanding the economic and geopolitical stakes of a war between Israel and Iran is not just for foreign policy experts it is essential knowledge for everyone, from business owners in Port of Spain to students in Kingston.

Energy shock: Why oil prices will skyrocket

A war between Israel and Iran would immediately disrupt oil flows through the Strait of Hormuz, a narrow waterway through which roughly 20% of the world’s petroleum passes. Iran has previously threatened to close this strategic chokepoint if attacked, and in a wartime scenario, that threat becomes far more credible. Any disruption to this route would send oil prices soaring. Historically, during conflicts such as the Iran-Iraq War in the 1980s or the US invasion of Iraq in 2003, global crude prices jumped sharply.

If Brent crude moves from US$80 to over US$150 per barrel, the ripple effect would reach every economy. Trinidad and Tobago, while an energy producer, is also an importer of refined fuels. A sudden spike in prices would strain government fuel subsidies, raise transport and shipping costs, and inflate the cost of goods and services. Caribbean economies already grappling with inflation, public debt, and post-pandemic recovery would face renewed pressure.

Global markets in turmoil

Beyond oil, a war in the Middle East would likely shake financial markets. Investors tend to flee to safety during international crises. This would boost gold and US dollar holdings, but emerging markets—including those in Latin America and the Caribbean—would face outflows of capital. Trinidad and Tobago’s Heritage and Stabilisation Fund could buffer some of the shock, but the stock market and foreign investment landscape would turn volatile.

Tourism-dependent economies like The Bahamas, Jamaica, and Saint Lucia would see potential declines in arrivals, particularly from Europe, if global travellers choose to stay home amid rising fuel prices and safety concerns. Insurance premiums for regional shipping and air travel could also rise, squeezing the already narrow margins of Caribbean importers and logistics providers.

US and NATO response: A broader military escalation

If Israel launches a pre-emptive strike against Iranian nuclear sites or military infrastructure, Iran is expected to retaliate not just against Israel but also against US bases in the Gulf. The United States, which maintains military assets in Qatar, Bahrain, Kuwait, and the UAE, would likely respond with air and naval power. NATO involvement would not be far-fetched, particularly if any Western assets are attacked directly.

This escalation could quickly engulf Syria, Iraq, Lebanon, and Yemen, destabilising the entire Middle East. As the region slips into chaos, supply lines for everything from electronics to fertiliser may be disrupted. Caribbean importers, who already face container shortages and currency fluctuations, would have to navigate yet another wave of uncertainty.

Iran’s allies and the proxy network

Iran maintains a vast network of proxy groups, including Hezbollah in Lebanon, Hamas in Gaza, the Houthis in Yemen, and various Shia militias across Iraq and Syria. These groups may attack Israel’s borders or disrupt maritime trade routes, particularly the Red Sea and the Eastern Mediterranean. This would make shipping insurance more expensive and lead to rerouted trade flows.

Even though the Caribbean is geographically distant, it is economically tied to the same shipping and commodity markets. For Trinidad and Tobago, this could mean delayed imports of food, medicine, and industrial goods. With supply chains already fragile due to global inflation, another shock could drive up local prices.

Cyber warfare and global infrastructure

Both Israel and Iran possess advanced cyber warfare capabilities. In the event of war, cyberattacks could hit utilities, banks, airports, and communications infrastructure not just in the Middle East, but globally. The US, UK, and parts of Europe would likely be targeted as supporters of Israel, and retaliatory cyber operations could cause collateral damage.

For the Caribbean, where many governments and businesses have rapidly digitised operations post-COVID, this presents a real threat. Cyberattacks on international payment systems could delay wire transfers, shut down websites, and interrupt access to online services. Individuals and small businesses in Trinidad and Tobago could face temporary outages in banking or mobile payment apps, disrupting daily transactions.

Caribbean security and migration risks

Although direct military threats to the Caribbean are unlikely, secondary effects are not. Increased instability in the Middle East could push more refugees towards Europe and North Africa, but also potentially to Latin America. Regional migration flows might increase from Venezuela or Haiti if their economies are further strained by rising global food and energy prices.

More broadly, countries in the Western Hemisphere might need to reallocate development aid or humanitarian assistance budgets toward Middle Eastern crises, reducing support for Caribbean resilience programmes. Local governments might be forced to reprioritise resources away from climate adaptation or healthcare in response to surging import costs or social unrest tied to inflation.

Impact on the Trinidad and Tobago economy

The Trinidad and Tobago economy would experience a complex mix of positive and negative effects. On the positive side, higher global oil and gas prices could boost government revenues from exports of LNG, ammonia, and methanol. This would increase fiscal space in the short term.

However, the flip side includes higher costs for imported refined fuels and increased demand for US dollars, putting pressure on the already strained forex market. If the Central Bank has to intervene more aggressively to defend the exchange rate, it may reduce the availability of foreign reserves for other priorities. Inflation would rise, particularly for imported goods such as vehicles, electronics, and pharmaceuticals.

Manufacturers who depend on imported raw materials might face delays and cost overruns. Local retailers would pass on higher prices to consumers, further eroding household purchasing power. Tourism, which is a growing secondary pillar in Tobago, may also see a dip in arrivals if international travel slows down amid the crisis.

How individuals can prepare

For residents of Trinidad and Tobago and across the Caribbean, preparing for the fallout of a distant conflict might seem unnecessary. But the financial and economic consequences will be real. Here are some concrete steps individuals should consider:

First, reduce debt exposure. In a high-inflation environment triggered by war, interest rates tend to rise. Avoid taking on new high-interest loans, and prioritise paying off existing variable-rate debts.

Second, build a three-to-six-month emergency fund in a mix of TTD and USD, if possible. Diversifying savings helps hedge against currency fluctuations and unexpected job losses or business disruptions.

Third, review your food and medicine stockpiles. Supply chain issues can lead to temporary shortages. Stock up modestly on non-perishables and essential medicines. Don’t panic buy, but be sensible about potential delays.

Fourth, secure your digital life. Ensure all banking apps and business software are updated, backed up, and protected with strong passwords. Cyber disruptions are increasingly likely in any modern war.

Fifth, consider fixed-price energy contracts for businesses or households with high consumption. Locking in prices before oil spikes further can offer financial predictability. Explore energy efficiency measures where feasible, such as switching to LED lighting or better insulation.

Finally, stay informed. Rely on reputable news sources and government updates. Misinformation spreads quickly during global crises and can lead to bad financial or business decisions. Watch for advisories from the Ministry of Trade, the Central Bank, and the Ministry of Energy and Energy Industries.

A distant war with local consequences

While a war between Israel and Iran may appear far removed from Caribbean life, its effects would be felt across every sector of the global economy. From fuel prices at the pump in San Fernando to shipping delays in Bridgetown, the war’s impact would be real and immediate. For Trinidad and Tobago, the challenge will be in balancing the windfall from higher energy prices with the broader economic pressures that come with global instability.

For individuals, preparation is no longer optional it is a necessity. Whether you are an entrepreneur in Chaguanas, a nurse in Scarborough, or a student in St Augustine, taking proactive steps now could make a real difference in maintaining financial stability and peace of mind during turbulent times. The world is more interconnected than ever, and in today’s global village, even a regional war can reshape lives thousands of miles away.
