UNITED NATIONS, Jul 23 2026 (IPS)

Prior to the latest round of hostilities between the United States and Iran, freight traffic had been increasing in the Strait of Hormuz, and negotiations were underway for a new agreement to fully restore trade through this channel.

According to UN Trade and Development (UNCTAD), energy markets were likely to bounce back to normal pre-conflict levels faster than that of food, public finance, and transport, leaving many vulnerable economies worse off. UNCTAD research shows a change from about 125 daily ship transits through the Strait of Hormuz in 2026, January 1st through February 27th, to a drop of around 10 daily transits from February 28th through June 14th during the conflict, marking a 92 percent decrease in overall transit ability.

According to UNCTAD and the Strait of Hormuz monitor, levels on June 2nd recorded around 40 ship transits, with an average of 60 through the days after signing the MOU (The Memorandum of Understanding signed by both US and Iranian delegations). This represents roughly half of pre-conflict transit levels.

Note: Daily outbound shipments represent AIS-traceable crude oil tanker departures from the Strait of Hormuz to destinations outside the Persian Gulf. Additionally, this graph is roughly similar to overall shipments of LNG, fertilizer, and Agricultural products through the same period.

Following the closure of the Strait, the daily price of crude oil jumped to USD 120 per barrel, then averaged around USD 100 per barrel throughout the conflict. The daily price of crude oil fell to USD 70 per barrel upon the signing of the MOU, roughly returning to pre-conflict levels. However, following the latest escalations and the breaking of the MOU, crude prices have risen again to approximately USD 100, indicating that agreements to cease conflicts can quickly bring prices down significantly, if agreed to once more.

On the contrary, the IGC Grains and Oilseeds Freight index (GOFI), indicates a slow decrease of the heightened costs of transporting both grains and oilseeds by sea (e.g., Wheat, Corn, Barley, Sorghum, Soybeans, Rapeseed (canola), Sunflower seed), across 68 key exporting origins in the regions of the United States, The European Union, Canada, the Black Sea region, Brazil, Australia, and Argentina.

Note: The index is normalized so that 100 represents the average grain and oilseed freight rate on January 1, 2013. During the conflict, the index rose to approximately 190, representing a 90 percent increase relative to the base value and a 30 percent increase from the beginning of the conflict on February 28, 2026.

As a result of the heightened price of grains and oilseeds, among other agriculture components, UNCTAD says, “Past input price shocks remain a risk to future food security,” laying out the cycle in which costs can amount:

1. Traffic through the strait was disrupted.
2. Limited freight traffic constricts the availability and raises the cost of oil, gas and nitrogenous fertilizer.
3. A decrease in energy exports creates higher energy prices, increasing transport and shipping costs.
4. Further fuel inflation slows down the global economy.
5. Agricultural production costs increase.
6. Food production may be affected by the increased cost of agricultural components such as fertilizer, pushing domestic food prices further up.
7. Vulnerable populations may face greater food insecurity and hunger, as a result of the heightened cost of importing food, and domestic agriculture production.

This process has exposed 61 vulnerable economies to dual impact of higher oil and cereal import prices. (e.g., wheat, rice, corn, barley, oats, sorghum, millet, rye) These countries consist of 35 least developed countries and 26 small island states, with seven of those countries being both least developed and small island developing states.

According to UNCTAD, the pressure is “sharpest for economies that rely heavily on imported fuel”, citing an example in Cabo Verde where net imports of oil and petroleum products averaged 24.6 percent of GDP within recent years. This dependence on fuel imports means that those extra costs can quickly make food prices, electricity, transport, and public finances more expensive.

Yemen was also cited to be at high risk, with analysis showing that net imports of cereal and cereal products averaged 10.8 percent of GDP. For countries like Yemen dealing with conflict, hyperinflation, debt pressure, and limited public financing, a higher import bill for grain compounds an already declining situation.

UNCTAD analysis indicates that a real increase of food cost by just 5 percent is associated with a higher risk of child wasting (a life-threatening form of acute malnutrition), especially among poor children and children living in rural landless households.

While restoring full trade through the strait is a necessary step to recovery, this will not undo the aftermath that higher import bills, delayed shipments, and higher priced food and energy have on the global economy, especially vulnerable economies.

“The policy task is therefore broader than reopening a route. Vulnerable economies need support to manage higher import bills, protect households from food and fuel shocks, and invest in systems that reduce exposure before the next disruption hits household budgets,” said UNCTAD, indicating the importance for vulnerable economies to develop supply chain resilience, sustainable systems, and have less reliance on concentrated international trade for vital goods such as food and energy, among financial support from the international system.

Every morning, as the Indian Ocean retreats from the reef off Zanzibar’s Jambiani village, Chiku Chande steps into the knee-deep lagoon carrying bundles of seaweed seedlings. Years of farming these waters have taught her about every channel and coral outcrop. But lately, the corals that once glowed in brown and gold have become chalky white.

“You don’t need anyone to tell you these changes,” Chande tells IPS. “We see it with our own eyes. The coral has lost its colour.”

Like many families in Jambiani, the 48-year-old grandmother depends on the reef. It shelters her seaweed farm from crashing Indian Ocean waves, supports fish stocks and brings tourists to the village. As the corals bleach and slowly die, she worries about the future.

Chande has watched the reef change year after year. Scientists say her observations mirror what is happening across the world’s tropical oceans.

Scientists long regarded El Niño – the natural warming of parts of the Pacific Ocean that disrupts weather patterns globally – as the main driver of mass coral bleaching

A new study led by Climate Central and published in Oceanography concludes that human-induced climate change has driven every global coral bleaching event over the past four decades. The researchers found greenhouse gas emissions have warmed the oceans so much that El Niño now acts mainly as a trigger rather than the root cause.

“Our study shows that without climate change, coral bleaching would be a rare and isolated event, and global mass coral bleaching simply would not occur,” says Andrew Pershing, Climate Central’s chief programme officer and the study’s lead author.

Corals bleach when unusually warm water forces them to expel the microscopic algae that provide most of their food and give them their vibrant colours. If temperatures quickly return to normal, corals can recover. But prolonged heat starves them and can kill entire reef ecosystems.

To determine how much of that warming came from human activity, researchers compared today’s sea surface temperatures with computer simulations of a world unaffected by greenhouse gas emissions. They then assessed whether bleaching would still have occurred under those cooler conditions.

Their analysis showed that every global bleaching event since 1998 – including those in 1998, 2010, 2014-2017 and the ongoing event that began in 2023 – required human-caused warming to push ocean temperatures beyond bleaching thresholds. Although El Niño coincided with many of those events, the study found they would not have become global bleaching episodes without decades of warming driven by fossil fuel emissions.

The findings have particular implications for Tanzania.

The country’s 1,400-kilometre coastline, which includes the reefs surrounding Zanzibar, Pemba and Mafia islands, supports fisheries, tourism and thousands of coastal livelihoods. Healthy reefs also protect beaches and coastal settlements by absorbing up to 97 percent of incoming wave energy, reducing erosion and storm damage.

As reefs deteriorate, fish populations decline, tourism suffers and coastlines become increasingly vulnerable to flooding and erosion.

Similar pressures are happening across tropical reefs worldwide. Although coral reefs cover less than one percent of the ocean floor, they support roughly a quarter of all marine species and generate an estimated US$2.7 trillion annually in ecosystem services through fisheries, tourism and coastal protection. The Global Coral Reef Monitoring Network estimates the world lost about 14 percent of its coral between 2009 and 2018 as repeated marine heatwaves left reefs too little time to recover.

Recent ocean temperature records suggest the pressure is intensifying.

According to the Copernicus Marine Service, June 2026 was the warmest June on record for global sea surface temperatures, while marine heatwaves covered about 82 percent of the world’s oceans by the end of the month. Because the oceans absorb more than 90 percent of the excess heat trapped by greenhouse gases, marine heatwaves are becoming more frequent and severe, increasing the likelihood of coral bleaching.

The Climate Central researchers project that by 2028 human-caused warming will outweigh El Niño’s influence in every coral reef region worldwide. Bleaching, they say, will increasingly reflect persistently warmer oceans rather than unusually strong natural climate cycles.

Using the same attribution methods, the researchers also assessed bleaching risk during the developing 2026-2027 El Niño. They found that while the climate pattern could still trigger bleaching in some regions, human-caused warming would account for most of the risk, particularly in the southern Caribbean, the Pacific coasts of Central and South America, and parts of East and Southeast Asia.

Globally, the monthly average sea-surface temperature for the extra-polar ocean (60°S–60°N) was the highest for June, exceeding the previous record set in June 2024 by just 0.01ºC. This partly reflected the development of strong El Niño conditions in the equatorial Pacific, according to the Copernicus Climate Change Service. Credit: ECMWF/Copernicus Climate Change Service

The study challenges the long-held assumption that bleaching is mainly a response to natural climate cycles. Researchers say bleaching can no longer be viewed as an occasional event linked to natural climate cycles; scientists say it is increasingly becoming a recurring consequence of steadily warming oceans.

“By isolating the effect of climate change, our study shows that the fate of reefs is closely tied to how much carbon pollution goes into the atmosphere. Protecting reefs from overfishing and pollution is very important. We need as many thriving reef areas as possible. Even during severe events, there are often pockets of coral that persist. These areas can be the source for recovery in the short and long term,” Pershing tells IPS

The Intergovernmental Panel on Climate Change warns that even if global warming is limited to 1.5 degrees Celsius above pre-industrial levels, up to 90 percent of the world’s coral reefs could disappear by mid-century. At 2 degrees Celsius of warming, losses could reach 99 percent.

Chande does not speak in terms of climate attribution. She only knows the reef looks different from when she began farming seaweed. Researchers say the bleaching she has witnessed reflects a much deeper shift: oceans that have steadily warmed over decades because of greenhouse gas emissions.

“When I was younger, the corals were full of colour and fish,” she said. “Now everything looks white. I worry about what is happening to the sea,” she says.
