September 26, (THEWILL) – Nigeria’s budget deficits remain exceptionally high, partly driven by heavy debt servicing obligations. Like many sectors, the blue economy is facing a severe capital shortfall. It requires about $10 billion in investment over the next ten years to fully unlock its potential. The current federal budgetary allocation of ₦10.5 billion remains grossly inadequate to drive meaningful impact. The funding gap is huge, and public finance alone is no longer enough. This lack of investment has left the sector’s opportunities underutilised for many years. The prospects span shipping, fisheries and aquaculture, marine tourism, coastal infrastructure, renewable energy, and ocean research. The sector needs urgent patient capital to support large-scale infrastructure development. The situation is further complicated by annual fish imports of $1.2 billion to address a domestic supply shortfall of about 2.2 million metric tonnes. This import dependence further drains the country’s foreign exchange earnings and undermines stability.
More than 90 percent of Africa’s trade moves by sea. With its strategic location along the Atlantic Ocean, Nigeria can become a dominant coastal transportation and maritime logistics hub in Africa. This potential for improved coastal trade provides a gateway into West and Central African markets. Nigeria can position itself to capture a larger share of the continent’s logistics value chain through projects like the regional Sealink Initiative, promoted by Nigeria’s Export–Import Bank (NEXIM). Such projects could create the corridor needed to evacuate major industrial projects while quickly easing port congestion. Moreover, domestic room for growth in aquaculture can bridge local fish supply deficits. A comprehensive policy framework was approved by the Federal Government in May 2025, providing a roadmap for harnessing Nigeria’s vast coastal and inland water resources. Yet mobilising capital for implementation remains a challenge.
Innovative financing is essential to diversify the economy without worsening public debt. Alternative financing mechanisms, including blue bonds, blended finance, and thematic instruments, can mobilise billions in new capital for infrastructure development in Nigeria. The funds could modernise ports and logistics infrastructure, expand aquaculture and cold-chain facilities for fisheries, restore mangroves and wetlands, and upgrade wastewater treatment plants and pollution-control systems.
Blue finance is a rapidly growing area of climate finance that directs investments toward projects and infrastructure that support a sustainable blue economy. It directs capital towards the sustainable use of oceans, seas, and freshwater resources. It involves specialised financial instruments such as blue bonds, blue loans, and debt-for-nature swaps. Appetite for blue finance is driven by increased interest from investors, financial institutions, and issuers globally. Blue bonds are specialised debt instruments used for marine protection, sustainable fisheries and coastal infrastructure. Seychelles issued the world’s first sovereign blue bonds in 2018 and raised $15 million for marine conservation and fisheries governance. In 2023, Gabon issued a $500 million sovereign blue bond as a debt-for-nature swap to refinance national debt and fund marine conservation. Recently, Kenya announced a blue bond program to fund aquaculture, maritime infrastructure, coastal resilience and fisheries. In 2023, the International Capital Market Association (ICMA) issued voluntary standards for initiatives to be considered eligible for blue bond issuance.

Nigeria has great potential and growing demand for blue bonds. The country possesses the financial liquidity and economic need for such bonds. However, it currently lacks a de-risked operational ecosystem to support market readiness. Experts suggest that governments should embed blue finance in national development plans, provide capacity-building for relevant stakeholders, and strengthen performance metrics and transparency standards. Development banks and multilateral institutions should consider providing tailored technical assistance and concessional capital to de-risk such capital investments. Co-created investment platforms and blended finance mechanisms should be encouraged to provide incentives and share risks. Professionals are actively advocating for the deployment of sovereign and corporate blue bonds in Nigeria. However, a structured, functional domestic blue bond market does not yet exist. After the issuance of green bonds in 2025, the regulatory environment seems to have slipped into official inertia. Nevertheless, a few commercial banks continue to pay some attention to projects that mainstream sustainability, yet many of them lack specialised marine lending frameworks.
Blue finance must become the preferred option for capital mobilisation as Nigeria seeks to diversify away from oil dependence. The extensive mangroves and coastal ecosystems in the Niger Delta offer entry points into the blue carbon market. These sustainable nature-based solutions provide revenue streams that tie direct capital flows to environmental preservation. For instance, as part of clean-up efforts at oil-polluted sites in the Niger Delta, thousands of mangrove seedlings have been replanted. Scaling up such initiatives can give coastal communities a ladder into the carbon marketplace. To incorporate sustainability into Nigeria’s ongoing reform efforts, more attention should focus on sustainable finance options, especially blue finance and blue bonds. Governments in coastal states looking to fund large-scale ocean-related projects and wastewater infrastructure can consider issuing blue bonds as a preferred approach to raise funds.
