Maritime Piracy Sees Resurgence in Key Global Shipping Lanes

Maritime piracy, once on the decline, is witnessing a notable resurgence in 2025. Recent incidents across critical shipping corridors—including the Gulf of Guinea, Singapore Strait, and waters off Somalia—highlight evolving threats that challenge global maritime security. This uptick underscores the need for continued vigilance and adaptive strategies to safeguard international trade routes.

Gulf of Guinea: A Return of Threats

After a period of relative calm, the Gulf of Guinea has experienced renewed pirate activity. In April 2025, a Marshall Islands-flagged chemical tanker was boarded approximately 100 nautical miles southwest of Brass, Nigeria. Four individuals approached the vessel in a skiff, boarded it, and stole cash before fleeing. This marked the first such incident in Nigerian waters since 2021, signaling a potential resurgence in the region.

Security firms report that this incident is among five boardings in the Gulf of Guinea in 2025, indicating a 30% increase in activity compared to the same period in 2024. ​


Singapore Strait: Escalating Incidents

The Singapore Strait has emerged as a hotspot for maritime piracy in early 2025. The International Maritime Bureau (IMB) recorded 27 incidents in the first quarter, a significant rise from seven incidents during the same period in 2024. ​

In one notable case, a Marshall Islands-flagged bulk carrier was boarded by four individuals while transiting eastbound through the Philip Channel. The intruders, armed with knives, boarded the vessel, which continued on its original route after the incident. ​


Somalia and the Horn of Africa: Persistent Challenges

Piracy off the coast of Somalia, which had seen a decline in recent years, is showing signs of resurgence. In February 2025, suspected Somali pirates seized a Yemeni fishing boat near the town of Eyl. The attackers stole personal items and two skiffs before abandoning the vessel upon the arrival of European naval forces. ​

This incident is part of a broader pattern, with seven reported piracy incidents off Somalia's coast in 2024. Factors contributing to this uptick include regional instability and the diversion of naval resources due to other global conflicts. ​


Southeast Asia: Heightened Precautions

While the threat level in the Sulu-Celebes Sea has been downgraded to "low" as of January 2025, maritime operators remain cautious. In March, the cruise ship Queen Anne implemented heightened security measures while transiting the area, including dimming lights and advising passengers to draw curtains, as a precaution against potential piracy threats. ​


Global Overview: Rising Concerns

The IMB reported a total of 45 cases of piracy and armed robbery against ships in the first three months of 2025, representing an almost 35% increase compared to the same period in 2024. This rise is primarily driven by the spike in incidents in the Singapore Strait.

Evolution of Maritime Piracy Tactics (2020–2025)
Tactic 2020–2022 2023–2025 Shift
Attack Zones Focused on Gulf of Guinea and East Africa Rising cases in Singapore Strait and reemergence in Somalia
Boarding Techniques Multiple armed attackers, often with RPGs Smaller groups using stealth and knives for low-level theft
Vessel Targets Large tankers and cargo ships Bulk carriers, fishing vessels, and supply ships
Hostage Scenarios Extended crew kidnappings for ransom Fewer hostage situations; quick robbery and escape
Operational Range Up to 200 NM offshore using motherships Closer to shore, in high-density traffic corridors
Note: Tactical trends based on data from IMB, ReCAAP, and industry security bulletins (2020–2025).

The resurgence of maritime piracy in 2025 reflects a shifting security landscape in global shipping. From the Gulf of Guinea to Southeast Asia, these events are prompting shipping companies, coastal states, and international security coalitions to reevaluate their protective strategies and preparedness measures.

Key conclusions from the latest piracy developments:

  • Gulf of Guinea incidents may signal a trend reversal
    • The robbery of a chemical tanker off Nigeria marks the first such event in four years, breaking a promising streak of regional calm.
    • The incident suggests pirates may be testing the waters in light of reduced foreign naval presence.
  • Singapore Strait has become the global hotspot
    • A 285% increase in Q1 2025 incidents vs. Q1 2024 has made this one of the most dangerous transit corridors.
    • Most boardings are low-level robberies, but the frequency poses cumulative risks to crew safety and cargo insurance ratings.
  • Piracy off Somalia is no longer dormant
    • Hijackings and armed boardings involving dhows and fishing boats have reappeared.
    • Political instability and gaps in regional coordination are giving pirate groups renewed opportunity.
  • Southeast Asia remains cautious despite downgrade
    • While some areas like the Sulu-Celebes Sea have improved, operators are still enforcing elevated security protocols on passenger vessels and tankers.
    • Proactive deterrence (like route lighting adjustments and secure communication protocols) is being normalized.
  • Global reporting and early warning systems are vital
    • The IMB’s alerts, ReCAAP data, and regional coordination centers have become frontline tools in piracy prevention.
    • Real-time reporting allows nearby ships to adjust course or increase watch readiness.
  • Stakeholders must not become complacent
    • The lull in piracy in recent years has led to scaled-down naval patrols and slower investments in anti-piracy tech.
    • A renewed commitment to training, surveillance, and collaboration will be key to preventing another 2008-style escalation.

As shipping lanes remain vulnerable to opportunistic attacks, maintaining strong multinational cooperation, investing in surveillance tools, and revisiting onboard safety protocols will be critical in ensuring maritime routes stay secure, resilient, and open for global trade.
