India’s Sagarmala Finance To Launch First Blue Bond For Maritime Infrastructure

Sagarmala Finance plans to raise up to 10 billion rupees ($105.08 million) through India’s first blue bond.
Proceeds will support maritime and coastal infrastructure, including ports, shipbuilding, inland waterways, and connectivity networks.
The deal would broaden India’s sustainable finance market beyond green bonds and address long-term funding gaps in maritime development.

India Prepares First Blue Bond For Maritime Finance

India is preparing to test investor appetite for its first blue bond, as state-owned Sagarmala Finance Corporation moves to raise long-term capital for maritime and coastal infrastructure.

The lender plans to issue up to 10 billion rupees, or about $105.08 million, including a greenshoe option of 5 billion rupees. Managing Director L.V.S. Sudhakar Babu told Reuters the bond will help diversify Sagarmala’s funding base and support projects tied to India’s maritime economy.

A blue bond is a debt security designed to finance ocean and water-related projects. It targets investors with mandates for environmental, social, and governance assets, particularly those linked to marine protection, water systems, coastal resilience, and sustainable infrastructure.

India has seen growing activity in green bonds, which finance climate and transition projects. However, Sagarmala’s proposed debt would be the country’s first blue bond, putting maritime finance into a more defined ESG investment category.

Why The Bond Matters For India’s Maritime Strategy

Sagarmala was established in 2016 under India’s Ministry of Ports, Shipping and Waterways. It received a non-banking financial company licence in June 2025, giving it a formal platform to expand lending for maritime infrastructure.

The company is expected to play a central role in financing projects that strengthen India’s maritime ecosystem. These include greenfield and brownfield ports, last-mile port connectivity, shipbuilding, inland waterways, and coastal road networks.

Reuters previously reported that Sagarmala plans to raise as much as 100 billion rupees in financial year 2027. That scale reflects India’s broader policy priority to modernise logistics, reduce transport bottlenecks, and build more efficient trade corridors.

For executives and investors, the planned blue bond adds a new layer to India’s sustainable finance market. It could create a dedicated funding route for assets that sit at the intersection of trade, coastal development, and climate resilience.

Longer-Term Funding Is A Core Driver

The proposed bond also addresses a practical balance sheet problem for Sagarmala.

Babu said the company’s existing term loans have an average tenor of 3.5 years. By contrast, the average tenor of the loans it disburses is about 12 years. That creates an asset-liability mismatch, which can increase refinancing risk for a lender backing long-cycle infrastructure.

A blue bond with a longer tenor could better match Sagarmala’s lending profile. It may also attract investors looking for ESG-labelled debt with exposure to infrastructure, public policy priorities, and India’s trade growth.

The exact tenor and rate have not yet been finalised. Trust Capital, AK Capital, and Tipsons have been appointed as advisers to the bond issue. A launch date has also not been set.

“This will happen when the market is conducive and yields stabilise,” Babu said.

Market Conditions Could Shape Timing

The timing of the issuance will depend heavily on India’s bond market conditions.

India’s benchmark 10-year yield has risen around 35 basis points since the start of the U.S.-Iran war. That move has weighed on bond market activity and made issuers more cautious about pricing new debt.

For Sagarmala, yield stability will be important. A poorly timed issue could raise borrowing costs and reduce the appeal of a first-of-its-kind instrument. A successful deal, however, could give other Indian issuers a template for blue finance.

Globally, blue bonds remain a small but growing part of sustainable debt. Just over $15 billion in blue bonds had been issued by mid-2025, according to World Bank data. The Bank of China issued Asia’s first blue bond in 2020, while island nations such as Seychelles have also used the format to finance ocean-related priorities.

India’s entry into the market would carry regional significance. The country has a long coastline, large port ambitions, and rising demand for climate-aligned infrastructure capital. A successful Sagarmala issue could widen the market for labelled debt in Asia and give investors a clearer route into maritime transition assets.

For the C-suite, the message is direct: blue finance is moving from niche sovereign and multilateral activity into national infrastructure strategy. In India, that shift could shape how ports, waterways, shipbuilding, and coastal networks are financed in the next phase of growth.
