A new financial projection from Standard Bank predicts that liquefied natural gas (LNG) exports will generate roughly €11 billion ($13 billion) annually for Mozambique once the three major offshore developments reach full operational capacity—a transformation that could reshape Portugal's energy security and economic relationship with this lusophone nation.
Why This Matters
• €9.6 billion in annual GDP expansion and €3.5 billion in tax revenue could stabilize Mozambique's sovereign debt and strengthen fiscal relations with Portugal.
• ExxonMobil's Rovuma LNG project is expected to trigger a final investment decision in September 2026, unlocking €26 billion in capital and first exports by 2030.
• Security risks persist in Cabo Delgado province, despite TotalEnergies' January 2026 restart of its €17.5 billion Mozambique LNG facility after a five-year suspension caused by Islamic State-linked violence.
• Portugal's historical ties to the lusophone nation mean ripple effects for trade finance, diaspora remittances, and regional energy security.
The Three Giants Reshaping the Rovuma Basin
The Rovuma Basin—straddling the offshore waters of Mozambique's Cabo Delgado province—is home to an estimated 160 to 200 trillion cubic feet of recoverable gas reserves, making it one of the largest untapped natural-gas provinces on the planet. Three multinational operators are racing to convert those subsea deposits into revenue streams.
TotalEnergies formally restarted construction at its Mozambique LNG site in Afungi in January 2026, mobilizing more than 4,000 workers—over 3,000 of them Mozambican nationals—after suspending the €17.5 billion project in April 2021 due to militant attacks. The facility is designed to produce 13 million tonnes per annum (mtpa) of LNG, with first cargo now scheduled for the first half of 2029. Company chairman Patrick Pouyanné told media in March 2026 that security guarantees are in place and the project "will never stop again."
ExxonMobil's Rovuma LNG venture, located in Area 4 of the basin, lifted force majeure in November 2025 and is on track for a final investment decision in September 2026, according to ExxonMobil Mozambique managing director Arne Gibbs. The €26 billion development will have an 18 mtpa capacity and deliver first exports in 2030. A joint report by Standard Bank and consultancy Conningarth Economists forecasts the project will add €70 billion ($81 billion) to Mozambique's sovereign wealth fund by 2056 and lift GDP growth to 4.1% on an annualized basis.
Eni, through its Mozambique Rovuma Venture consortium, already operates Africa's first floating LNG facility—Coral Sul FLNG—which has been shipping roughly 3.5 mtpa since 2022 and has completed over 120 cargo loadings. The Italian major's €6.3 billion Coral Norte project is slated to double Area 4 output when production begins in 2028, generating an estimated €20 billion ($23 billion) in tax revenue over 30 years. In June 2026, Eni launched a competitive tender for a third floating unit with a nominal capacity of 6 mtpa, targeting a 2031 start-up date. If sanctioned, Eni's total offshore liquefaction capacity in Mozambique would reach approximately 13 mtpa.
What This Means for Portugal: From Energy Security to Economic Opportunities
For residents living in Portugal, Mozambique's LNG boom carries direct implications—from energy bills and supply stability to job creation and trade opportunities across the economy.
Energy security and supply contracts: The European Union's pivot away from Russian pipeline gas has made African LNG strategically attractive for household and industrial consumers. Portugal, which imports almost all its natural gas and relies on the Sines regasification terminal, could negotiate long-term offtake agreements with Mozambican suppliers, diversifying away from Algerian and Nigerian cargoes. Diversifying LNG sources can help stabilize natural gas prices for Portuguese households and reduce vulnerability to supply disruptions or price volatility from traditional suppliers. This translates to more predictable energy costs and greater energy independence for families and businesses across the country.
Financial services and project finance: Standard Bank is already positioned as the lead adviser and lender in the sector; Portugal-based Banco BPI and Caixa Geral de Depósitos may explore co-financing or trade-finance facilities as Mozambican tax revenues improve debt sustainability ratios. The World Bank and African Development Bank have both activated integrated safeguard systems for the gas projects, creating openings for Portuguese consultancies specializing in environmental and social risk management.
Diaspora remittances and GDP feedback loops: Mozambique's per-capita income could rise 21% over the next decade if the projects hit their targets, according to the Standard Bank–Conningarth report. Higher household earnings typically translate into increased remittances to Portugal's Mozambican diaspora community, which numbers in the tens of thousands and sustains cross-border retail and real-estate flows.
Construction and logistics exports: With TotalEnergies employing up to 7,000 workers during peak construction and ExxonMobil's development requiring massive fabrication and logistics support, Portuguese engineering firms and equipment suppliers can compete for tenders, particularly in marine services, catering, and prefabricated modules. These projects create employment opportunities for Portuguese workers and engineers across multiple sectors.
The Persistent Shadow of Insurgency
Despite the restart euphoria, Islamic State-affiliated militants remain active in pockets of Cabo Delgado. TotalEnergies suspended its €17.5 billion project in 2021 after an assault on the town of Palma displaced thousands and killed dozens. The five-year hiatus pushed first LNG delivery from July 2024 to 2029, wiping out early revenue forecasts.
In March 2026, United Nations human-rights experts issued a public warning against financing Eni's Coral Norte development, citing the risk of "aggravating human-rights violations" and diverting scarce public resources from post-conflict reconstruction. The experts noted that over one million people have been displaced by the insurgency since 2017, and that security forces have been accused of beatings and movement restrictions.
The Mozambique government, backed by Rwandan and Southern African Development Community (SADC) troops, has regained territorial control over key gas-field zones, but sporadic attacks continue. Investors and insurers are watching closely: any new escalation could trigger fresh force majeure declarations and further delay production timelines.
Sovereign Wealth Fund Under Scrutiny
Mozambique established its Sovereign Wealth Fund (FSM) to channel gas revenues into budget stabilization and intergenerational savings. Under the current model, 60% of gas income flows to the national budget for immediate spending, while 40% goes to the FSM. In 2026, the fund is projected to receive roughly €26 million ($30.7 million) from LNG royalties, with the remainder allocated to social and economic programs outlined in the national budget.
The Central Bank of Mozambique (Banco de Moçambique) manages the FSM's assets, which are invested in financial institutions in Canada, Japan, and France. Governance includes a Supervisory Committee, an Investment Advisory Council, quarterly investment reports, and annual audits by the Administrative Tribunal and an independent international auditor.
Yet civil-society groups—including the Centre for Public Integrity (CIP) and the Budget Monitoring Forum (FMO)—have raised red flags. Critiques focus on insufficient detail in government reports, the absence of returns on idle balances, temporal inconsistencies in revenue declarations, and the presence of government-linked figures on the Investment Advisory Council, which may compromise independence. In early 2026, the FMO objected to the approval of a new FSM investment policy without civil-society consultation, warning that opaque governance undermines public trust.
For Portuguese financial institutions and stakeholders considering Mozambican sovereign bonds or investment partnerships, these governance concerns matter: the difference between a transparent, professionally managed wealth fund and a politicized slush fund can determine whether debt sustainability improves or collapses under the weight of hidden liabilities.
Environmental and Social Backlash Gains International Traction
The Rovuma Basin overlaps with the Quirimbas Biosphere Reserve, a UNESCO-recognized zone of coral reefs, seagrass beds, and mangroves. Environmental groups warn that the combined footprint of three mega-projects poses irreversible damage to marine ecosystems, food security, and climate resilience.
Estimated CO₂ emissions from the TotalEnergies Mozambique LNG facility alone could reach 18 million tonnes per year, totaling as much as 4.5 billion tonnes over the project's lifespan. Methane leakage, chemical and acoustic pollution, ballast-water introduction of invasive species, and dredging of Palma Bay for LNG-carrier traffic compound the environmental toll. Critics argue that Environmental Impact Assessments (EIAs) submitted for regulatory approval contain significant scientific gaps regarding terrestrial and marine biodiversity and fail to quantify cumulative climate effects.
On the social side, thousands of families have been physically and economically displaced, often after inadequate consultation and without dignified compensation. Local communities—predominantly reliant on fishing, subsistence farming, and forest resources—report minimal access to permanent employment due to high illiteracy rates and limited vocational training. Allegations of beatings and movement restrictions by government security forces have been documented by human-rights monitors.
The "Say No to Gas! in Mozambique" campaign and Justiça Ambiental! (Friends of the Earth Mozambique) are pressing international financial institutions to suspend new fossil-fuel project approvals and apply the precautionary principle until ecological and climate impacts are fully understood.
For Portuguese companies and institutions participating in the supply chain, these controversies carry reputational and legal risks. The European Union's emerging due-diligence directives on corporate sustainability mean that firms involved—even indirectly—may face liability if environmental and human-rights safeguards are not demonstrably robust.
A High-Stakes Bet on Fiscal Transformation
Bernardo Aparício, Standard Bank's Mozambique chief executive, framed the gas windfall as a fiscal game-changer: "Tax revenues will play a fundamental role in reducing sovereign debt and strengthening public investment, while driving economic growth." The bank's projection of €3.5 billion in annual tax receipts would represent a seismic shift for a country that ranks as the fifth-poorest in the world by per-capita GDP and whose public finances were battered by post-election violence in late 2024, forcing suspension of an International Monetary Fund (IMF) adjustment program.
Yet the timeline is long and fragile. ExxonMobil's 2030 start-up is still four years away, and TotalEnergies' 2029 target hinges on uninterrupted construction and stable security. Eni's third floating unit remains a paper proposal awaiting competitive bids and final investment approval. Meanwhile, Mozambique's debt-sustainability indicators remain under IMF red-flag status, and any revenue shortfall could trigger a debt spiral that erodes the sovereign wealth fund's intended cushion.
Portugal's exposure to Mozambican sovereign risk is significant: Caixa Geral de Depósitos holds Mozambican government bonds, Portuguese construction firms have signed memoranda of understanding for infrastructure contracts, and bilateral trade in goods and services exceeded €500 million in 2025. If the gas projects deliver as forecast, Lisbon stands to benefit from a more creditworthy partner and expanded export markets. If insurgency flares again or environmental litigation stalls production, Portuguese lenders and contractors will share the downside.
The Global LNG Landscape and Mozambique's Rank
Once all three developments are online, Mozambique is projected to become the fourth-largest global supplier of LNG, behind the United States, Qatar, and Australia. That trajectory positions the country as a swing supplier to European and Asian spot markets, with potential leverage over pricing and contract terms.
For Portugal's energy strategy, direct LNG import agreements with Mozambique could complement existing Algerian pipeline gas and Nigerian spot cargoes, reducing concentration risk and improving bargaining power vis-à-vis traditional suppliers. The Sines LNG terminal—operated by REN Atlântico—has spare regasification capacity that could accommodate additional Mozambican volumes without infrastructure upgrades.
The €70 billion sovereign wealth fund projection through 2056 assumes stable production, disciplined fiscal management, and no major geopolitical shocks. History suggests caution: Angola's oil windfalls were undermined by corruption and Dutch disease, while Nigeria's gas ambitions have repeatedly stumbled over pipeline sabotage and contract disputes. Mozambique's success will hinge on transparent governance, genuine local-content development, and sustained security in Cabo Delgado—none of which can be taken for granted.
