Key points: Frequent attacks and military deterrence in the Strait of Hormuz, Red Sea, Black Sea, and Sea of Azov are disrupting normal global shipping routes. Approximately 80% of global merchandise trade by volume relies on maritime transport, and disruptions to key sea lanes can drive up prices for energy, food, and consumer goods. Shipping companies are weighing rerouting options, insurance premiums, and inventory stockpiling, while closely monitoring emerging geopolitical risks on routes like the Panama Canal.

A satellite image from April 16, 2026, shows the Russian port of Tuapse. A Ukrainian drone strike on oil storage facilities at the Tuapse refinery, operated by a Russian oil company, ignited a massive fire visible for kilometers, causing multiple explosions and billowing smoke across this Black Sea port city. The Strait of Hormuz is disrupting global trade, but this waterway is just a microcosm. Drones and missiles are now targeting economic lifelines, turning numerous critical maritime chokepoints into frontline zones of geopolitical confrontation. From the Strait of Hormuz and the Red Sea to the Black Sea, commercial vessels are being attacked, trade operations are disrupted, and shipping insurance and freight rates are rising across the board. Shipping companies are being forced to reassess routes once considered safe and stable.

The cost of geopolitical games is steep: about 80% of global freight volume is carried by sea. Even a single major shipping lane blockage can cause cargo delays, material shortages, and widespread price increases for energy, food, and daily necessities, even thousands of miles away.

Drones are reshaping naval warfare. David Roche, president and global strategist at Quantum Strategy Consultancy, noted in a July report on the situation in the Sea of Azov and the Black Sea, stating that "new maritime chokepoints are being born, and a new form of warfare has begun." Ukraine has frequently used drones to attack Russian tankers. Roche defines this conflict as the first major naval offensive conducted almost entirely by drones, supplemented by missiles. These weapons allow a less powerful military to threaten ships, ports, and other infrastructure at a low cost, and damage to facilities can cause immense economic losses. Quantum Strategy estimates that about 25% of Russia's grain exports and 25% to 30% of its Black Sea oil exports are at risk of disruption. Russia accounts for over one-fifth of global cross-border wheat trade, and instability in the region can easily move global food prices.

Yevgeniya Gaber, a senior fellow at the Atlantic Council think tank, stated that Russia's suspension of vessel passage through the Kerch Strait earlier this month directly cut off a key maritime route. "Maritime transport in the Sea of Azov was becoming an increasingly important backup route to Russia's land corridor to occupied Crimea," Gaber explained via email. "The economic impact is also significant, as the Sea of Azov handles not only sanctioned crude oil and refined products but also grain, coal, and steel exports." Gaber evaluated that Ukraine's precise strikes on Russia's maritime transport capacity and economic lifelines represent one of the most severe blows to a wartime military and commercial fleet since World War II. Ukraine claims to have degraded about one-third of the Russian Black Sea Fleet's combat capability since 2022.

The Panama Canal may become the next geopolitical flashpoint. Attacks continue along the Strait of Hormuz, and the security situation on the waterway remains volatile. Even when governments declare a channel open, shipowners decide whether to transit based on the probability of vessel attacks and crew casualties. Li Dajin, global head of research at freight consultancy Fertistream, said, "The market often treats the risks in the Strait of Hormuz, the Black Sea, and the Bab el-Mandeb as isolated events, which is not the case. Against the backdrop of a major geopolitical shift towards a new world order, these waterways are being turned into battlefields one by one." New risks are already emerging. Lars Jensen, CEO of maritime consultancy Vespucci Maritime, predicts, "If we are to forecast the next geopolitical hotspot, the focus is not on Hormuz, but on the Panama Canal." This century-old waterway, connecting the Pacific and North Atlantic, has long served as a shortcut for deep-sea shipping, but is now deeply entangled in a three-way power struggle involving the US, China, and Panama. Jensen added that a drought is highly likely to reduce the canal's transit capacity in late 2026 and early 2027, further escalating geopolitical tensions.

The impact on shipping is far greater than commonly perceived. For shipping companies, the dilemma is that old shipping lanes have not yet stabilized before new maritime chokepoints emerge. Kevin O'Marah, co-founder and chief research officer at supply chain intelligence firm Zero100, told the publication that Iran has discovered it can disrupt transport merely by threatening shipping in the Strait of Hormuz, turning this waterway into the central battleground of US-Iran confrontation. While no ships belonging to Zero100's clients have been attacked in the strait, many companies have proactively adjusted inventories and rerouted vessels to avoid risk. "Some clients in the energy, food, and electronics sectors are bearing additional freight costs and cargo delays." "Current traffic through the Strait of Hormuz is only half of normal levels. The collapse of the ceasefire has exacerbated the situation, but supply chain professionals anticipated this. Leading logistics companies like Mars and Maersk have long had mature risk management protocols in place." On April 21, 2026, Iranian Revolutionary Guard vessels intercepted commercial ships in the Strait of Hormuz. Earlier, markets feared no resolution to the Middle East crisis, driving oil prices higher; Iran restricted strait traffic, and the US imposed a blockade on Iranian ports. O'Marah outlined corporate hedging strategies: oil can be transshipped via pipelines across the Arabian Peninsula; some goods can be transported overland to Turkey; and more cargo ships are avoiding the high-risk waters of the Middle East whenever possible. Most supply chain managers believe the Middle East conflict will not escalate indefinitely, but the freedom of navigation through the Strait of Hormuz is likely to remain under pressure for the long term. "We are prepared for the long haul, accepting the normalization of shipping uncertainty, and bearing the ongoing costs of rerouting, stockpiling, and shipping surcharges."

Alain Bejjani, a Dubai-based investor, business executive, and guest on a Lebanese venture capital program, noted that the reason shipping lanes remain a focal point of conflict is fundamentally because the conflict itself relies on shipping. "The battlefield has shifted from territorial land grabs to logistics lifelines. A missile strike doesn't directly close a strait; it's when insurance companies refuse to underwrite that the route truly shuts down. This form of confrontation is cheap to maintain and hard to quantify, which is why the deadlock persists." A spokesperson for insurance broker Gallagher stated that war risk insurance, covering losses from war, terrorist attacks, and civil unrest, remains available, but few shipowners and charterers choose to transit the Strait of Hormuz. "The maritime security environment is severe, and war risk premiums are higher than usual. Premiums vary based on vessel type, cargo, and route; maritime insurance institutions continue to underwrite, ensuring sufficient risk coverage for international trade."

Companies are facing long-term changes in managing maritime geopolitical risks. Bejjani believes the structural and profound impact of maritime geopolitical conflicts is underappreciated by the public. "The Persian Gulf has two chokepoint straits, not just Hormuz. The entire Middle East is now planning logistics to maximize the use of both the Strait of Hormuz and the Bab el-Mandeb." "This is different from past crises: companies previously only did short-term hedging, but this time it is forcing the formation of a new logistics system – cross-border land corridors, bypass pipelines, and pre-positioned warehousing in core consumer markets. This entire infrastructure is enormously expensive, takes a decade to build, and its effects will last for decades. Other regions dependent on strait shipping will likely follow suit, but will not match the Middle East's level of attention and resource investment."

On July 25, 2026, vessels transited the Bab el-Mandeb Strait off southern Yemen. The Houthi group stated on July 24 that it would not block this strategic waterway; later that week, the group announced a maritime embargo on Saudi Arabia and subsequently attacked a Saudi commercial vessel in the Red Sea. Simultaneously, Iran blockaded the Strait of Hormuz, creating a risk correlation between the two major waterways, threatening the energy exports of Saudi Arabia, the world's top oil exporter. Bejjani predicts that maritime transport will retain its volume advantage, but the absolute commercial trust in shipping will be lost. "Categories with high stability requirements will greatly expand multimodal transport; the logistics system will permanently add redundant capacity, with related costs incorporated into regular pricing." "The straits will eventually reopen, but the era of free and unimpeded passage is gone forever."
