Global military spending rises for 11th year, SIPRI says
SIPRI’s April 28, 2026 report finds global military spending rose for an 11th consecutive year, highlighting open-data limits and regional drivers and policy.
The Stockholm International Peace Research Institute (SIPRI) reported on April 28, 2026 that global military spending increased for the eleventh straight year, driven by sustained procurement and rising defence budgets in multiple regions. The report, based on open-source and official data, notes that not all expenditures are captured in publicly available figures. Analysts say the trend reflects persistent geopolitical tensions and an acceleration of arms acquisition programs worldwide.
SIPRI report records eleventh straight annual increase
SIPRI’s assessment presents a clear year-on-year rise in global military spending, marking the longest consecutive growth period in recent records. The institute attributes the trend to expanded budgets, modernization efforts and, in some cases, emergency acquisitions related to active conflicts.
The report emphasizes that the increase is widespread, affecting both high-spending powers and middle-income states that have boosted forces and procurement. SIPRI frames the rise as the outcome of strategic choices by governments responding to perceived threats and opportunities in a shifting security environment.
Report relies on open-source and official data, with gaps
SIPRI’s dataset draws primarily on government reports, budget documents and other public sources, a methodology that the institute calls both rigorous and necessarily incomplete. The organisation warns that opaque defence accounting, classified programs and unilateral secrecy mean some spending is likely understated or omitted.
This reliance on open data makes the findings verifiable but also highlights limitations when comparing countries with different transparency standards. Researchers and policymakers caution that hidden expenditures, such as covert procurement or paramilitary financing, can skew the global picture.
Regional drivers: Europe, Asia and the Middle East
In Europe, prolonged insecurity and the fallout from large-scale conflicts have prompted sustained increases in defence allocations and rapid procurement cycles. Governments across the continent have accelerated modernization plans and replenishment purchases to address shortfalls identified by recent operations.
Asia remains a major driver of spending growth as states invest in naval, air and missile capabilities amid strategic competition in the Indo-Pacific. Meanwhile, Middle Eastern spending continues to be shaped by regional rivalries and ongoing security crises that prompt arms acquisitions and domestic military spending.
Procurement trends and major buyers
SIPRI’s analysis highlights a tilt toward high-technology systems, including advanced aircraft, missiles and unmanned platforms, which carry long procurement timelines and high unit costs. Defence firms report steady demand for integrated systems and sustainment services, feeding a cycle of long-term contracts and follow-on spending.
Large military purchasers influence global supply chains and pricing, prompting suppliers to prioritize production scale and logistics capacity. Observers note that procurement decisions often lock in multi-year budgets, making short-term reductions in spending politically and technically challenging.
Implications for transparency and fiscal planning
The continued rise in global military spending raises questions about budgetary priorities and long-term fiscal sustainability for some states. Ministries of finance and parliaments face difficult trade-offs between defence investment and spending on health, education and infrastructure.
SIPRI calls for improved transparency and standardised reporting to allow better public scrutiny and more accurate international comparisons. Enhanced disclosure could help policymakers assess whether procurement programs deliver value and align with stated security objectives.
SIPRI’s latest findings underscore a sustained commitment by many governments to enlarge and modernise military forces, even as the institute warns that gaps in public data conceal parts of the global picture. As states plan future programmes, debates over transparency, procurement oversight and the balance between defence and social spending are likely to intensify.
