Southeast Asian nations are rethinking their energy strategies as the Middle East conflict disrupts oil supplies, pushing them to accelerate investment in renewables and nuclear power despite rising financing costs. This shift reflects both the urgency of securing energy independence and the long-term goal of building more sustainable economies.
On 1 April 2026, the Asian Development Bank (ADB) unveiled the Rapid Resource Reprogramming and Deployment Option (3RDO), a pioneering emergency financing mechanism designed to enable its developing member countries (DMCs) to respond with unprecedented speed and flexibility to crises. This announcement comes at a time of acute geopolitical and economic uncertainty, with the ongoing Middle East conflict amplifying risks across Asia and the Pacific, and a series of devastating natural disasters highlighting the region’s vulnerability. The 3RDO represents a significant evolution in the multilateral development bank toolkit, offering DMCs the ability to repurpose existing sovereign portfolio funds for immediate relief and early recovery—often within just 24 hours of a crisis declaration.
The closure of the Strait of Hormuz—one of the world’s most vital oil and gas arteries—has sent shockwaves through economies from Europe to Asia. The conflict has not only upended lives in the Middle East but also exposed a central vulnerability to our deep dependence on fossil fuels shipped through conflict-prone regions.
The Strait of Hormuz typically sees about 20% of the world’s daily oil supply and a significant share of liquefied natural gas (LNG) pass through its narrow waters. Since late February, however, shipping traffic has plummeted, with tankers anchored outside the strait and major shipping firms suspending operations. Oil prices have soared—Brent crude surged past $120 per barrel at its peak, and LNG prices have followed suit. For Southeast Asia, which relies heavily on imported energy, the impact has been immediate and severe.
The Economic Toll in Southeast Asia
Southeast Asia is home to some of the world’s fastest-growing economies, and energy demand has been rising by about 3% per year for two decades. Yet, nearly 80% of Southeast Asia’s energy still comes from fossil fuels, much of it imported.
As oil and gas prices have spiked, so too have costs for households and businesses. In the Philippines, diesel prices have jumped by as much as 80% since the conflict began, and gasoline is up by about 50%. The government’s own projections show that if oil prices were to remain at $150 per barrel for several months, inflation could soar to nearly 9%, unemployment could rise by over a percentage point, and poverty rates could climb above 12%. The poorest households, who spend more than 60% of their income on food, are feeling the pinch most acutely as higher fuel costs ripple through food prices and transport.
Bangladesh and Vietnam, both heavily reliant on imported LNG and oil, have faced similar pressures. Bangladesh, for example, is already running a significant structural gas deficit, and the loss of Qatari LNG shipments has forced the country to scramble for alternatives, often at much higher prices. Vietnam, meanwhile, has seen record coal imports and is racing to keep the lights on as hydropower output falters and LNG supplies dwindle.
Philippines
On 24 March 2026, Philippine President Ferdinand Marcos Jr. declared a state of national energy emergency, activating a whole-of-government response to safeguard energy supplies, support vulnerable sectors, and accelerate the transition to renewables.
The emergency measures are sweeping. The government has set up the Unified Package for Livelihoods, Industry, Food, and Transport (UPLIFT) Committee to coordinate fuel supply management, price controls, and social support for affected groups. Public offices have shifted to a four-day work week to conserve fuel, and there’s been a renewed push for energy efficiency across all sectors.
But the crisis has also turbocharged the Philippines’ long-term energy ambitions. The Department of Energy has launched a series of renewable energy auctions, including the country’s first offshore wind-only auction (GEA-5), which will offer 3,300 megawatts for delivery between 2028 and 2030. The government’s offshore wind roadmap, developed with the World Bank, identifies a technical potential of up to 178 gigawatts—enough to transform the country into a regional clean energy powerhouse.
At the same time, the Philippines is making serious moves toward nuclear energy. The nuclear roadmap includes plans for up to 4,800 MW of capacity by 2050, with a focus on small modular reactors (SMRs) that can be deployed in remote islands and replace aging coal plants.
The shift is not without challenges. Financing remains a major hurdle, with high capital costs and regulatory uncertainty slowing the rollout of both renewables and nuclear projects.
Vietnam
The Revised Power Development Plan 8 (PDP8), approved in April 2025, the government aims to cap coal-fired power, expand renewables to at least 47% of electricity generation by 2030, and introduce up to 6,400 MW of nuclear capacity by 2035. The Just Energy Transition Partnership (JETP), launched in 2023, has mobilised $15.5 billion in international finance to support this shift.
The results are impressive: Vietnam has rapidly deployed solar and wind power, with solar capacity jumping from just 4 MW in 2015 to over 16 GW by 2025. Rooftop solar is booming in cities, driven by manufacturers seeking to meet global sustainability standards. Offshore wind is emerging as a geopolitical asset, with European and Japanese investors co-developing projects along the coast.
Yet, the transition is far from smooth. The grid is struggling to keep up with the surge in renewables, leading to curtailments and lost revenue for investors. Transmission bottlenecks in the south and central regions have become a major headache, and the government estimates it needs about $18 billion by 2030 to upgrade the system.
Coal, meanwhile, is proving hard to quit. Despite ambitious targets, Vietnam hit a record-high in coal imports in 2025, reflecting both energy security concerns and the need to sustain rapid economic growth. The JETP, once seen as a game-changer, has faced setbacks after project cancellations and the withdrawal of some international partners.
Still, Vietnam’s pivot to renewables is reshaping the region’s energy landscape. The introduction of direct power purchase agreements (DPPAs) is allowing large companies like LEGO and Samsung to buy electricity directly from wind and solar producers, potentially doubling the renewable share in the power mix. The government is also piloting large-scale battery storage and grid modernization projects with support from the World Bank and Asian Development Bank.
Malaysia
Malaysia, traditionally an energy exporter, has found itself at a crossroads. While the country is less exposed to immediate supply shocks than its neighbours, the global price surge and supply chain disruptions have prompted a strategic rethink.
The government is now actively exploring nuclear energy as part of its long-term power mix. Deputy Prime Minister Fadillah Yusof has described the move as a strategic effort to strengthen energy security and support clean energy goals, especially amid geopolitical uncertainty and fuel price volatility. MyPOWER Corporation, under the Energy Transition and Water Transformation Ministry, is leading a comprehensive assessment covering policy, legal frameworks, project feasibility, and stakeholder engagement.
Nuclear is not intended to replace existing sources like solar, hydro, or gas, but to complement them and ensure a stable, low-carbon baseload. The government is also considering small modular reactors (SMRs), which offer flexible deployment and lower upfront costs.
At the same time, Malaysia is pushing ahead with corporate renewable energy schemes. The Corporate Renewable Energy Supply Scheme (CRESS) and new guidelines for aggregation mechanisms are enabling large electricity consumers to purchase green power directly from developers, using the national grid for wheeling. These initiatives are attracting multinational investment and supporting grid modernization.
The private sector is responding enthusiastically. Data centres, manufacturers, and logistics companies are signing up for long-term power purchase agreements (PPAs) to secure reliable, low-cost, and clean energy. The result is a growing ecosystem of rooftop solar, distributed energy, and digital solutions that is helping Malaysia stay competitive in the global green economy.
Grid Integration and Nuclear Dialogue
The crisis has shown the importance of regional cooperation. The Association of Southeast Asian Nations (ASEAN) is moving from strategic planning to operational action, with the ASEAN Power Grid (APG) at the heart of its energy integration agenda.
The APG links national power networks, enabling countries to trade electricity and integrate more renewables across borders. Projects like the Lao PDR–Thailand–Malaysia–Singapore Power Integration Project have already doubled cross-border capacity, and new submarine interconnections are in the works. By 2040, the APG aims to support a 52% renewable energy share in the region’s power mix, create 1.45 million green jobs, and avoid 60 million tonnes of fossil fuel consumption.
Nuclear energy is also gaining traction as a regional solution. ASEAN’s Civilian Nuclear Energy framework is fostering dialogue on safety, regulation, and capacity-building, with support from the IAEA and World Bank. The Philippines and Indonesia are leading the way on SMRs, while Vietnam and Malaysia are revisiting nuclear as part of their diversification strategies.
International institutions are playing a key role. The World Bank’s decision to lift its ban on nuclear financing, the IAEA’s capacity-building support, and blended finance initiatives from the Asian Development Bank are all helping to lower the cost of capital and de-risk investments.
The Financing Challenge
Despite the momentum, financing remains a stubborn barrier. Clean energy investment in Southeast Asia is still well below what’s needed to meet climate and energy targets. The International Energy Agency estimates that annual investment must rise fivefold, from $19 billion in 2025 to $95 billion by 2035, to stay on track.
The weighted average cost of capital (WACC) for solar PV in the region is 8–9%—higher than in advanced economies—and even higher for offshore wind and battery storage. Regulatory risk, transmission bottlenecks, and slow permitting processes add to investor uncertainty. The pipeline of bankable projects is limited, and many countries lack clear, consistent frameworks for procurement and pricing.
Blended finance—combining public and private capital—has been promoted as a solution, but results have been mixed. For every $1 of concessional public finance, only about $1–$2 in private finance has been mobilized, far below the $4–$7 assumed in many models. Most of the money still goes to middle-income countries, with low-income nations like Bangladesh receiving a small share.
To unlock more investment, experts say the region needs a common investment hub, guarantee mechanisms to reduce funding costs, and streamlined regulatory processes. Regional cooperation, such as the ASEAN Power Grid and cross-border project aggregation, can also help lower costs and spread risk.
Traditional emergency financing mechanisms, while essential, often require weeks or months to mobilise new funds, leaving critical gaps in the immediate aftermath of a disaster. As ADB President Masato Kanda noted at the launch of 3RDO, “Speed is crucial to protect the economy and the most vulnerable during a crisis, and this new tool gives our developing members the means to act in days, not weeks or months, when their people need support the most”.
The 3RDO is designed to address this “golden window”—the first days after a disaster or emergency—when governments must secure essential goods, maintain public services, and stabilise their economies. By enabling the rapid repurposing of undisbursed ADB sovereign portfolio funds, the mechanism allows DMCs to bridge the gap between immediate needs and the arrival of new financing.
The road ahead won’t be easy. Financing, regulation, and infrastructure remain major hurdles. But with strong leadership, regional cooperation, and the right mix of policy, technology, and investment, the region can turn crisis into opportunity—and lead the way in the global green transition.
As the UN Secretary-General put it, “energy security is no longer just about supply, but also about resilience and finding alternative power sources in an increasingly unstable world”. For Southeast Asia, the future is being written now—one solar panel, one wind turbine, one bold policy at a time.
