The Red Sea has become a place where commercial timetables depend on military protection. Reuters reported on September 17 that Italy was preparing a naval mission to protect its merchant shipping around Bab al-Mandeb. The European Union's Operation ASPIDES was already escorting ships through the same waters. The immediate story is therefore about naval activity. The larger one is about how a trade route that once depended mainly on geography has come to depend increasingly on security.

The Red Sea connects the Suez Canal to Bab al-Mandeb and the Gulf of Aden. Ships moving between Europe and Asia can save thousands of nautical miles by using the corridor instead of sailing around the Cape of Good Hope. That advantage explains why attacks on vessels near Yemen can affect insurance, freight rates and delivery schedules far beyond the region.

The crisis that began in 2023

The current security architecture dates from late 2023, when Houthi forces in Yemen began attacking commercial shipping in the Red Sea. The attacks were linked by the Houthis to the war in Gaza, while shipping companies and governments focused on the immediate threat to crews and navigation. In December 2023 the United States announced Operation Prosperity Guardian, a multinational initiative under the Combined Maritime Forces intended to protect freedom of navigation.

The European Union chose a separate model. In February 2024 it launched Operation ASPIDES. The EU describes the mission as purely defensive. Its mandate is to protect vessels, accompany ships and improve maritime situational awareness. It does not conduct strikes on land. That difference is important because public discussion often treats every Western naval vessel in the Red Sea as part of one operation. They are not.

ASPIDES reported early in 2024 that its ships had shot down drones that posed a direct threat to navigation. By August 2026 the mission said it had supported more than 2,390 merchant vessels and provided close protection to more than 720 ships since its launch. Its September notices continued to describe commercial vessels reaching their destinations under EU protection.

Shipping changed before the politics did

The commercial response was immediate. Some shipowners stopped using Bab al-Mandeb and the Suez Canal and rerouted around southern Africa. The U.S. Energy Information Administration estimated that oil flows through Bab al-Mandeb fell from 9.3m barrels a day in 2023 to 4.1m in 2024. In the first half of 2025 they remained at roughly 4.2m barrels a day.

At the same time, oil flows around the Cape of Good Hope increased sharply. EIA data show that flows around the Cape rose from about 6.2m barrels a day in 2023 to 9.3m in 2024. Liquefied natural gas traffic through Bab al-Mandeb fell close to zero in 2024 and the first half of 2025.

Those figures reveal a basic economic fact. Ships can avoid a chokepoint, but avoidance is not free. A longer route consumes more fuel, occupies a vessel for more days and complicates schedules. The cost can spread through supply chains even when cargo arrives safely.

Several naval missions, several mandates

The arrival of an Italian mission adds another layer to an already crowded security picture. Italy is also a participant in wider European and multinational maritime-security arrangements. The point is not simply the number of warships. It is the multiplication of authorities under which those warships operate.

Operation Prosperity Guardian sits under the Combined Maritime Forces and is associated with a U.S.-led multinational response. ASPIDES is an EU mission with a defensive mandate. Operation Atalanta, another EU mission, focuses principally on counter-piracy and maritime security in the western Indian Ocean and Gulf of Aden. National navies can also protect their own shipping. The same merchant vessel may therefore move through a sea protected by overlapping missions that answer to different political institutions.

The region had already accumulated one layer of maritime security before the Houthi crisis. The EU launched Operation Atalanta in 2008 to protect humanitarian shipping and deter piracy off Somalia. By 2026 it remained active alongside ASPIDES. The two missions illustrate how the Red Sea-Gulf of Aden system has acquired institutions in response to successive problems rather than through one master plan. Piracy produced one architecture; missile and drone attacks produced another.

That overlap can be useful. More surveillance, more escorts and more information-sharing can reduce vulnerability. It can also create a need for careful coordination. A shipmaster wants to know who is providing protection, under what rules and in which area.

Piracy returns to the picture

The resurgence of piracy in the Gulf of Aden adds another complication. In August 2026 the International Maritime Organization said a sixth vessel was being held by pirates and armed robbers and that more than 90 seafarers were captive. Piracy and Houthi attacks are different threats. One is principally a criminal ransom economy; the other is connected to regional conflict and military strategy. Yet they can affect the same shipping lanes.

That distinction matters operationally. A naval force optimized for missile and drone defence is not automatically configured for hostage rescue, boarding operations or tracking pirate motherships. The presence of warships therefore does not mean every maritime threat is covered equally.

For Puntland and the Horn of Africa, this overlap is especially important because vessels leaving Bab al-Mandeb enter the Gulf of Aden, where piracy, local fishing economies, commercial ports and naval patrols already coexist.

Why the Horn should care about rerouting

The economic consequences of Red Sea disruption are usually discussed in terms of Europe-Asia trade. The Horn sits inside the same system. Djibouti depends heavily on port activity and regional logistics. Puntland's Bosaso port serves the Gulf of Aden. Eritrea's Red Sea coastline places it along the wider maritime corridor. Changes in traffic patterns, risk premiums or naval deployments can therefore alter the operating environment for several Horn economies even when the ships involved are not calling at their ports.

There is also a strategic effect. More naval activity increases the attention of outside powers to a region that already hosts foreign bases and competing security partnerships. Djibouti's location has long made this visible. The current Red Sea crisis extends that strategic geography southward and eastward toward the Gulf of Aden.

What Italy's move means

Italy's reported decision should be read as evidence that governments no longer expect commercial shipping to manage the Red Sea risk on its own. The response has shifted from advisories and rerouting toward more formal protection. That does not guarantee a return to pre-2023 traffic patterns. Shipping companies will make decisions based on insurance, threat assessments, cost and reliability, not on political declarations alone.

The strongest indicator will therefore be behaviour. If more ships return to Bab al-Mandeb and Suez, the corridor's economic advantage may again outweigh the perceived security risk. If traffic remains diverted despite more escorts, the market will be signalling that naval protection has not yet restored sufficient confidence.

The Red Sea story is often told through explosions and warships. Its more durable measure may be quieter: which route captains and shipping companies choose. Naval missions can reduce risk. They cannot command confidence. That has to be earned voyage by voyage.
