Iran Warns of Possible Bab al-Mandab Blockade as Middle East Tensions Threaten Global Shipping and Energy Markets
Amid rising tensions in the Middle East, Iran has issued a stark warning that one of the world’s most strategically important maritime chokepoints, the Bab al-Mandab Strait, could face disruption if Israel intensifies its military campaign against Tehran.
The warning has renewed concerns about the stability of global trade routes and the potential impact on international energy supplies.
Ali Akbar Velayati, a senior adviser to Iran’s newly appointed Supreme Leader, Mojtaba Khamenei, suggested that forces aligned with the so-called “Axis of Resistance” possess the capability to block not only the Bab al-Mandab Strait but also the Strait of Hormuz if the regional conflict continues to escalate.
His remarks underscored Iran’s growing willingness to signal the strategic leverage it holds over some of the world’s most critical shipping corridors.
In a statement shared on social media platform X, Velayati cautioned that the current calm in the Bab al-Mandab should not be mistaken for weakness.
He argued that resistance groups operating across the region have the means to shut down both waterways if provoked further.
The message appeared to serve as both a warning and a call for restraint, urging adversaries to avoid actions that could push the region into a broader confrontation.
The warning came as Yemen’s Iran-backed Houthi movement claimed responsibility for another attack targeting Israel.
The group also announced that vessels linked to Israel would once again be considered legitimate targets in waters surrounding the Red Sea.
This declaration has heightened concerns about maritime security in the Red Sea, the Gulf of Aden, and the narrow Bab al-Mandab passage that links the two bodies of water.
The Bab al-Mandab Strait occupies a uniquely important position in global commerce.
Located at the southern entrance of the Red Sea, it serves as a crucial gateway connecting the Indian Ocean to the Suez Canal, one of the world’s busiest trade arteries.
The route enables the movement of goods between Europe, Asia, and the Middle East, making it indispensable to international shipping networks.
Geographically, the strait lies between Yemen on the Arabian Peninsula and the Horn of Africa nations of Djibouti and Eritrea.
At its narrowest point, the waterway is only around 29 kilometres wide, making it particularly vulnerable to military threats, blockades, or disruptions caused by regional conflicts.
The strategic significance of the Bab al-Mandab became evident in late 2023 when Houthi rebels began attacking commercial ships passing through the Red Sea.
The campaign was launched in response to Israel’s military operations in Gaza and quickly evolved into a major challenge for international shipping companies.
As attacks increased, many global shipping operators were forced to divert vessels away from the Red Sea and Suez Canal route, choosing instead the much longer journey around Africa’s Cape of Good Hope.
These detours significantly increased transportation costs due to higher fuel consumption, longer transit times, elevated insurance premiums, and additional expenses related to crew operations.
During the height of the campaign, the Houthis carried out more than 100 attacks against commercial and military targets. The assaults resulted in the deaths of at least nine mariners and the sinking of four vessels.
Analysts noted that several of the targeted ships had only indirect or minimal connections to Israel, highlighting the broad impact of the conflict on international maritime traffic.
The attacks severely disrupted commerce through the Red Sea, a route that had previously facilitated the movement of approximately $1 trillion worth of goods each year.
The instability affected supply chains across multiple continents, creating delays and increasing costs for businesses and consumers alike.
Egypt was among the countries hardest hit economically by the disruption. Reduced traffic through the Suez Canal significantly affected a vital source of foreign currency earnings.
In 2023 alone, the canal generated around $10 billion in revenue for Egypt, underscoring its importance to the country’s economy.
Despite repeated threats and attacks, the Bab al-Mandab Strait has remained open to navigation throughout the current conflict.
However, security concerns continue to influence shipping decisions, with many companies closely monitoring developments before determining their preferred routes.
Regional energy exporters have also sought alternatives to reduce their dependence on vulnerable maritime passages.
Saudi Arabia, for instance, has increasingly relied on its East-West Pipeline, which transports crude oil across the kingdom to ports on the Red Sea, providing an alternative to the often-sensitive Strait of Hormuz.
The economic importance of the Bab al-Mandab Strait extends far beyond regional trade. In 2024, an estimated 4.1 million barrels of petroleum and petroleum products passed through the waterway every day.
This accounted for roughly five per cent of global oil trade, illustrating the corridor’s critical role in maintaining stability in international energy markets.
Experts warn that any prolonged closure or significant disruption of the Bab al-Mandab Strait could have far-reaching consequences.
Global supply chains would face severe bottlenecks, shipping costs would likely surge, and oil prices could experience sharp volatility.
Such a scenario would not only affect countries in the Middle East but also have economic repercussions across Europe, Asia, Africa, and beyond.
As geopolitical tensions continue to simmer, the future security of the Bab al-Mandab Strait remains a matter of international concern.
With global trade and energy flows heavily dependent on this narrow maritime passage, any escalation in the region could quickly transform a local conflict into a worldwide economic challenge.
