Japan and the Philippines formally agreed in June 2026 to cooperate on building a national strategic oil reserve for Manila — a partnership struck under the Partnership for Wider Energy and Resources Resilience in Asia (PWERRA) framework. The deal, announced by DOE Secretary Sharon S. Garin, brings in Japan’s Ministry of Economy, Trade and Industry alongside Philippine state entities PNOC and Maharlika Investment Corp to develop the country’s first government-owned fuel stockpile.
The agreement marks a significant step for a nation that currently relies on industry-held inventories covering roughly 15 to 30 days of supply.
Philippines and Japan Formalize Oil Stockpile Partnership
Under the PWERRA framework, Japan’s Ministry of Economy, Trade and Industry and the Philippine Department of Energy agreed to advance cooperation on two parallel tracks: building a national stockpiling system for the Philippines and developing an ASEAN-wide joint stockpiling framework. Rather than direct funding alone, Japan’s contribution will flow through technical assistance, feasibility studies, and capacity-building programs — a structure built around practical delivery.
A technical mission of Japanese government officials and private sector representatives is expected to visit the Philippines before the end of 2026, moving early-stage planning into concrete project work. DOE Secretary Garin framed the goal plainly: ensuring the Philippines has enough fuel to withstand global market disruptions and protect its economy, industries, and households from external shocks.
Energy Emergency Declaration and Supply Vulnerability Drove the Initiative
The partnership did not emerge in a vacuum. On March 24, President Ferdinand Marcos Jr. declared a one-year state of national energy emergency, citing an imminent danger of critically low energy supply — triggered by the closure of the Strait of Hormuz, one of the world’s most consequential oil transit routes.
The Philippines’ exposure to that disruption is considerable. Saudi Arabia supplied 51.4 percent of the country’s crude oil imports in 2024, out of a total 45.37 million barrels. The UAE accounted for 30.9 percent, Iraq for 13.4 percent, and Qatar for 1.1 percent. The overwhelming majority of Philippine crude originates from Gulf states whose exports depend on Hormuz passage.
Private-sector inventories currently cover approximately 15 days of mandatory stock requirements, sometimes reaching 30 days depending on market conditions. The government considers this insufficient. Officials are now studying options to establish an additional strategic reserve that would extend the country’s buffer against unforeseen disruptions.
Project Structure: PNOC and Maharlika Investment Corp to Lead Implementation
The DOE is coordinating the reserve project with two state-linked entities. The Philippine National Oil Company will provide technical and industry expertise consistent with its energy security mandate, while Maharlika Investment Corp — the country’s sovereign wealth fund — will evaluate financing structures and investment options.
Phased rollout is expected, with feasibility studies, site evaluations, financing options, and implementation models currently being developed. No single construction timeline has been announced, which reflects where planning actually stands.
Japan’s side of the cooperation will involve JOGMEC — the Japan Organization for Metals and Energy Security — along with the Japan Bank for International Cooperation, Japanese trading companies, and engineering firms with stockpiling infrastructure expertise. Both governments are also exploring opportunities for Japanese institutions and private companies to participate in engineering, procurement, construction, and financing for future project phases.
Philippines Promotes ASEAN-Wide Oil Reserve as Regional Chair
The bilateral deal with Japan fits within a broader strategic ambition. As 2026 ASEAN Chair, the Philippines is actively promoting a regional oil reserve framework among Southeast Asian member states — a collective preparedness mechanism that members could draw on during fuel supply disruptions or energy emergencies.
Manila has expressed interest in hosting future strategic stockpiling facilities if ASEAN members decide to pursue the initiative. Cooperation with the Economic Research Institute for ASEAN and East Asia is also woven into the broader framework supporting this push.
A National Energy Emergency Response
The Japan-Philippines oil stockpile agreement is a direct response to a declared national energy emergency and a supply chain concentrated heavily in the Persian Gulf. Japan’s role covers technical expertise, feasibility work, and capacity-building, with JOGMEC and JBIC among the institutions involved. PNOC and Maharlika Investment Corp are leading implementation on the Philippine side, with phased development and financing models still under study. Beyond the bilateral arrangement, Manila is using its position as 2026 ASEAN Chair to push for a regional reserve framework — one it hopes to host — that would give Southeast Asia a collective defense against future supply disruptions.
