why does the suez canal keep getting blocked and what is the …!

The Suez Canal is one of the most critical waterways for global trade, handling nearly 12% of the world’s shipping traffic. However, in recent years, it has experienced multiple blockages, causing major disruptions to international supply chains. From the infamous Ever Given incident in 2021 to security threats in 2023-24, various factors contribute to these disruptions.
But why does the Suez Canal keep getting blocked, and what are the consequences of these obstructions? This article explores the root causes, the global impact, and potential solutions to prevent future incidents.
Causes of Suez Canal Blockages

Navigational Challenges and Ship Size
The primary reason for canal blockages is the increasing size of modern cargo vessels. The Suez Canal was initially designed for smaller ships, but today’s megaships—such as the Ever Given—have difficulty navigating its narrow passages. Several factors contribute to these incidents:
- The Bank Effect: As ships pass through narrow waters, hydrodynamic forces cause their stern to be drawn toward the canal’s banks, increasing the risk of grounding.
- Strong Winds and Weather Conditions: High winds and sandstorms make navigation even more difficult, often leading to ship instability.
- Human Error: Mistakes in manoeuvring massive vessels can easily result in a ship running aground, as seen in the Ever Given case.
Geopolitical Conflicts and Security Threats
Since late 2023, geopolitical instability has added another layer of risk. The Houthi militant attacks in the Red Sea, targeting cargo ships, have forced many vessels to avoid the Suez Canal entirely. Key concerns include:
- Drone and Missile Attacks: Several ships have been targeted, causing many shipping companies to take alternative routes.
- Increased Piracy Risks: Security threats in the region make it dangerous for vessels to pass through, further slowing down traffic.
- Egypt’s Economic Losses: The Egyptian government has reported losing around $7 billion in revenue due to reduced traffic.
Accidents and Mechanical Failures
Apart from large-scale incidents like the Ever Given, smaller accidents frequently occur. Some ships experience engine failures or rudder malfunctions, leading to temporary obstructions that slow down the flow of maritime traffic.
Implications of Suez Canal Blockages

Disruptions to Global Supply Chains
The Suez Canal is a major trade artery, and any blockage has ripple effects across the world. When a blockage occurs:
- Delays in Goods Delivery: Essential products such as oil, gas, food, and electronics get delayed, leading to shortages in many countries.
- Higher Shipping Costs: Freight rates skyrocket as companies are forced to reroute via the Cape of Good Hope, adding two weeks to transit times.
- Impact on Manufacturing: Industries relying on just-in-time inventory systems, like automotive and tech, suffer production delays.
Economic Consequences
The financial impact of a blocked canal is massive:
- Lost Trade Value: The Ever Given blockage alone held up nearly $60 billion worth of goods over six days.
- Increased Insurance Costs: With heightened risks, insurers charge higher premiums for ships passing through the canal.
- Egypt’s Revenue Decline: The Suez Canal generates billions in toll fees annually, but blockages and rerouted ships lead to significant financial losses.
Environmental and Energy Market Impact
Rerouting ships around Africa increases fuel consumption and carbon emissions. Additionally, a blocked canal can affect global oil and gas supplies, causing fuel prices to spike worldwide.
Preventive Measures and Solutions

Expanding and Upgrading the Canal
To accommodate larger vessels, the Suez Canal Authority (SCA) has launched projects to:
- Widen and deepen sections of the canal.
- Add additional passing lanes to reduce congestion.
- Improve waterway management with advanced navigation systems.
Enhancing Ship Safety and Navigation Rules
Authorities are working to improve pilotage regulations by:
- Mandating the use of multiple tugboats for megaships.
- Providing better real-time monitoring systems for incoming vessels.
- Conducting more rigorous simulated training for canal pilots.
Addressing Geopolitical Risks
To mitigate security threats:
- A stronger naval presence is needed to protect commercial ships in the Red Sea.
- Diplomatic efforts should focus on stabilizing the region to reduce attacks on vessels.
- More companies may start using alternative routes such as the Arctic passage if security risks persist.

FAQs
How often does the Suez Canal get blocked?
While major incidents like the Ever Given are rare, minor delays due to weather, mechanical failures, or accidents happen several times a year.
Why do ships like Ever Given get stuck?
Large ships struggle with the canal’s narrow width, and factors like strong winds, human error, and hydrodynamic effects increase the risk of grounding.
What happened to the Ever Given ship?
In March 2021, the Ever Given ran aground and blocked the Suez Canal for six days, causing billions in trade losses before being refloated.
What alternatives exist if the Suez Canal is blocked?
Ships can reroute around Africa’s Cape of Good Hope, but this adds up to 14 days of travel time and increases costs.
How does a blocked Suez Canal affect oil prices?
Delays in oil shipments lead to supply shortages, often causing spikes in global crude oil prices.
Conclusion
The Suez Canal plays a vital role in global trade, yet it remains vulnerable to navigational difficulties, geopolitical threats, and mechanical failures. Each blockage causes economic turmoil, supply chain disruptions, and environmental consequences. However, with ongoing expansion projects, improved navigation rules, and increased security measures, the future of the canal could be more resilient.
