Uranium market faces structural deficit as nuclear demand outpaces supply

The global uranium market is entering a period of structural deficit as surging demand for nuclear power outstrips the development of new mining capacity. A joint report published this week by the OECD Nuclear Energy Agency and the International Atomic Energy Agency indicates that while production has risen, it is not keeping pace with the rapid expansion of reactor construction, rising electricity consumption, and the power requirements of data centres. Benchmark Mineral Intelligence forecasts that the market is already in a marginal deficit in 2026, with the shortfall expected to widen to 18% of demand by 2027. This shift marks a decisive departure from the subdued market environment that prevailed following the 2011 Fukushima disaster.

Global exploration and development spending exceeded 1.78 billion dollars in 2023 and 2024, representing a 46% increase from the previous two years. Production responded to this investment, rising by approximately 20% over the same period to more than 116,000 tonnes of uranium. Output reached 61,924 tonnes in 2024 alone, the highest annual level recorded since 2016. However, Tony Alderson, uranium research manager at Benchmark, noted that the focus on future reactor capacity risks overlooking the scale of mined uranium supply required to support this growth. He stated that demand is being strengthened by renewed interest in nuclear power, including small modular reactors and advanced technologies, as well as growing requirements from artificial intelligence hyperscalers.

The core challenge is not the availability of uranium underground, but the speed at which miners can extract it. Identified global resources recoverable for less than 260 dollars per kilogram of uranium exceed 8.1 million tonnes, a volume sufficient to meet even the highest projected demand through 2050. Nevertheless, turning a discovery into an operating mine typically takes 15 to 20 years. As of January 1, 2025, there were 418 commercial nuclear reactors operating worldwide with 378 gigawatts of net generating capacity, requiring about 64,500 tonnes of uranium annually. Global nuclear capacity is projected to expand substantially through 2050, with annual uranium requirements potentially rising to between 84,800 and 143,900 tonnes by mid-century.

China is expected to be a major driver of this expansion. Its existing nuclear capacity of roughly 68 gigawatts is set to grow rapidly, with 42 gigawatts under construction and another 26 gigawatts planned. More than 30 gigawatts are under construction or planned elsewhere in Asia, while Europe has more than 20 gigawatts in the pipeline. The buildout coincides with increased electricity demand from data centres, where artificial intelligence and cloud-computing operators require large volumes of reliable, around-the-clock power. Small modular reactors could broaden the market further by offering smaller, replicable designs, though their near-term contribution to uranium consumption remains limited, with 73 tracked units expected to require less than 2,000 tonnes annually.

The supply response is strengthening, but much of the additional uranium has come from existing operations rather than new projects. The increase in 2023 and 2024 was driven mainly by restarting idled capacity and expanding existing mines, particularly in Canada. While several new projects received regulatory approvals, none began producing during the period. Exploration activity has accelerated, but drilling aimed at project development has remained stagnant. This disconnect is significant given the long timelines involved. Sustained investment is needed to identify deposits, secure permits, and finance construction before demand arrives. Alderson warned that the wider nuclear fuel cycle is also facing constraints, from conversion and fabrication capacity, and that substantial investment is required across the cycle to keep pace with demand.

Kazakhstan, which accounts for about 39% of global mined uranium, faces production constraints due to tight sulphuric acid supplies and skilled labour shortages. These supply issues also briefly halted production at Cigar Lake in Canada in July. Namibia offers another source of growth, having become the world’s third-largest producer following substantial Chinese investment, with output expected to continue expanding through 2030. However, new uranium supply can take about a decade to reach the market. The agencies conclude that adequate and sustained uranium prices, backed by long-term contracting, will be critical to maintaining exploration and supporting final investment decisions. Without immediate investment, the industry risks a deepening structural deficit and a more volatile price environment.
