US, Japan and South Korea Forge Nuclear Alliance as Uranium Contracting Shortfall Widens
Global utilities contracted 116 million pounds of uranium in 2025, below the replacement rate, as a new US-Japan-South Korea nuclear pact and SMR expansion lift long-term demand projections.
Japan and South Korea formalized a trilateral nuclear partnership with the United States on September 5 (2026-09-05), coordinating fuel supply strategies and accelerating reactor deployment as Northeast Asia's two largest economies embed nuclear power more deeply into their long-term energy security frameworks.6
The alliance comes as global uranium contracting consistently runs below consumption rates. Industry data published September 3 (2026-09-03) by USA News Group shows utilities placed roughly 116 million pounds of uranium under long-term contracts in 2025, still below the rate at which they consume the fuel. Uncovered requirements are accumulating year by year.4
Washington has moved to address the supply side. The Department of Energy in January 2026 awarded roughly $2.7 billion in contracts to expand domestic enrichment capacity, coupled with restrictions on Russian uranium imports and a Section 232 review covering the entire fuel cycle, USA News Group reported. The combined effect pushes US utilities toward securing more domestically enriched product at a time when contracting is already running short.4
The IEA, in its Global Critical Minerals Outlook 2026, put current annual uranium demand at close to 70 kilotonnes of natural uranium equivalent. The agency projects strong growth as nuclear generation capacity expands globally.3
New bilateral supply deals reflect that expectation. A contract signed in 2026 between Kazatomprom and India's Department of Atomic Energy was valued at over $4 billion and received 92.9% shareholder approval, ranking among the largest uranium supply arrangements in Asia and exceeding 50% of Kazatomprom's total export volume, according to Geopolitical Monitor. For the world's largest uranium producer, that single deal absorbs a substantial share of annual output.2
China is compounding demand from both sides. Beijing's 15th Five-Year Plan for its energy system, published in June 2026, covers a domestic nuclear build-out and the active deployment of Chinese reactor technology and financing across Southeast Asia. The US is competing directly for those same contracts, making fuel supply terms a geopolitical instrument as much as a commercial one, The Diplomat reported.5
Europe is also reversing course. European Commission President Ursula von der Leyen described Europe's retreat from nuclear power as a "strategic mistake" in March 2026 and pledged €200 million for a new generation of small modular reactors.1
SMRs bring an additional demand curve. Technology companies are positioning nuclear as dedicated low-carbon baseload for data centers. The IEA estimates US data-center power demand alone will more than triple over the next decade, from 34.7 gigawatts in 2024 to 106 GW by 2035. Microsoft, Amazon and Google have all signed deals with nuclear developers, according to Forbes.1
Nuclear investment globally has grown more than 70% over the past five years. The IEA expects nuclear spending to exceed $100 billion annually under stated policies and projects more than 70 GW of new capacity online by the mid-2030s, one of the strongest pipelines in 30 years, Forbes reported. But this capacity does not arrive on a quarterly timeline.1
The URA uranium equity ETF was trading at $41.70 on September 16 (2026-09-16), broadly unchanged in the session. Spot and equity pricing has not fully absorbed the contracting shortfall data because the physical demand surge, linked to new builds and SMR fleets still in development, sits years out. Utilities covered by existing long-term agreements have near-term insulation. The gap between those contracts and future requirements is where pressure builds.4
The near-term signal is the US Section 232 review outcome. Broad import restrictions would tighten enriched product availability for American utilities faster than new domestic capacity can fill the gap. Whether the Japan-South Korea-US alliance produces coordinated purchasing that lifts 2026 contracting volumes above the 116 million pounds placed in 2025 is the number that will tell uranium market participants whether policy convergence is translating into physical demand.6,4
