India's MAHASAGAR Doctrine Shifts Indian Ocean Strategy
Prime Minister Narendra Modi's three-day state visit to Seychelles from June 27 to 29, 2026, has formalized India's evolved maritime doctrine, MAHASAGAR. The visit, hosted by President Patrick Herminie for Seychelles' Golden Jubilee, produced a $175 million economic package, security asset transfers, and nine bilateral agreements. This signals a strategic shift toward integrating climate resilience, digital infrastructure, and maritime security in the Indian Ocean Region.
What does the MAHASAGAR doctrine mean for the Indian Ocean?
India's maritime policy has transitioned from the 2015 SAGAR framework, which focused primarily on regional security and growth, to the more multidimensional MAHASAGAR, standing for Mutual and Holistic Advancement for Security and Growth Across Regions. This updated doctrine acknowledges that maritime safety is deeply connected to climate action, ecological sustainability, and digital integration. For a nation like Seychelles, which boasts a landmass of just 460 square kilometres but commands an Exclusive Economic Zone (EEZ) of over 1.3 million square kilometres, this approach offers a more comprehensive security model.
Seychelles sits adjacent to critical Sea Lines of Communication that underpin global trade and energy supply chains. By treating the safety of Seychelles as an extension of its own coastal security, India is making a pragmatic calculation. The MAHASAGAR framework aims to prevent the Indian Ocean from becoming a theatre of geopolitical friction, advocating instead for a free, open, and rules-based maritime order. This aligns with broader Australian and multilateral interests in maintaining regional stability.
How does the $175 million package strengthen Seychelles?
The visit yielded a $175 million Special Economic Package structured as a hybrid financing mechanism. It combines a $125 million rupee-denominated Line of Credit with a $50 million direct grant. This calibration accounts for Seychelles' economic vulnerabilities, ensuring the grant element allows the credit to be absorbed sustainably over time, with rupee disbursements processed in India.
Alongside financial support, India transferred significant operational assets to the Seychelles People's Defence Forces. The handover included a Fast Patrol Vessel, five high-speed laser-guided boats, six medical ambulances, and ten heavy-duty utility vehicles. These assets are designed to counter contemporary asymmetric threats. While piracy dominated regional security concerns in the early 2010s, the current challenges revolve around illegal, unreported, and unregulated fishing, narcotics trafficking, and climate-induced natural disasters. India has also agreed to positively consider a new request for an Advanced Light Helicopter, further solidifying rapid-response HADR capabilities.
Climate action and the blue economy take center stage
President Herminie conferred the Guardian of the Blue Horizon presidential distinction upon Prime Minister Modi, recognizing India's advocacy for the Global South and its investments in the blue economy. This award carries weight in the context of international climate finance. While global forums frequently stall on delivering mitigation and adaptation funds to developing nations, India has opted for direct bilateral action. By actively funding and implementing climate resilience projects, India is positioning itself as a practical partner for small island states facing acute environmental vulnerabilities.
Digital infrastructure and economic integration
The partnership is moving beyond traditional donor-recipient dynamics toward a hybrid investment ecosystem. A major step is the introduction of India's Digital Public Infrastructure, modeled on the Unified Payments Interface, which will advance financial inclusivity and e-governance across the archipelago. Economically, there is potential for government-backed credit to leverage private-sector capital, opening avenues for sustainable tuna processing for global export and expanded tourism infrastructure.
The two nations also signed nine bilateral agreements, notably a landmark Extradition Treaty. As Seychelles grows as a regional financial services hub, this treaty serves as a legal safeguard, preventing the exploitation of its financial systems. Additionally, ground was broken on a Professional and Technical Training Institution, with plans for a specialized hospital, aimed at upskilling the local workforce for a service-dominated economy. The 15,000-strong Indian diaspora continues to serve as a living bridge in this evolving relationship.
What are the implications for Australia's Indo-Pacific strategy?
From an Australian perspective, India's deepened integration with Seychelles is a welcome development. A stable Indian Ocean Region is fundamental to Australia's own security and economic interests. India's deployment of Coastal Surveillance Radar Systems and maritime surveillance aircraft in Seychelles extends a technical security umbrella that complements Western and regional monitoring efforts. By weaving together security hardware, digital empowerment, and climate resilience, India is establishing a model of development partnership that reinforces the rules-based order in the Indo-Pacific.
What is the difference between SAGAR and MAHASAGAR?
SAGAR, introduced in 2015, stands for Security and Growth for All in the Region, focusing primarily on maritime security and basic regional cooperation. MAHASAGAR, or Mutual and Holistic Advancement for Security and Growth Across Regions, expands this scope to integrate climate action, ecological sustainability, economic resilience, and digital infrastructure into maritime governance.
Why is Seychelles strategically important to India?
Seychelles controls an Exclusive Economic Zone of over 1.3 million square kilometres, situated near vital Sea Lines of Communication for global trade. India views securing this area as essential to its own coastal defense, ensuring safe passage for energy supplies and countering asymmetric threats like illegal fishing and narcotics trafficking.
What security assets did India provide to Seychelles?
India provided a Fast Patrol Vessel, five high-speed laser-guided boats, six medical ambulances, and ten heavy-duty utility vehicles. These join previously supplied Dornier maritime surveillance aircraft and a Coastal Surveillance Radar System, significantly enhancing Seychelles' capacity to monitor its vast EEZ.
