SIPRI Annual Report 2025: Trends, Challenges, and Policy Implications

The SIPRI Annual Report 2025 highlights the dual tension between global strategic stability and the steady expansion of nuclear capabilities by states. This creates a paradox: while arms control frameworks aim to curb proliferation, modernisation programmes intensify. This issue anchors debates under GS-III (Internal Security and Defence), particularly under "Science and Technology developments and their application in Defence" and "Challenges to Internal Security through external threats."

Arguments Supporting SIPRI Findings

The SIPRI Report 2025 presents concrete evidence of an ongoing arms race in multiple regions. The report underlines the failure of nuclear disarmament frameworks and highlights the significant uptick in military expenditure, even amidst global economic challenges. This points to states pursuing hard power over cooperative security arrangements.

• Nuclear Expansion: The report reveals a rise in total nuclear warheads to 12,241. China added 100 warheads annually since 2023 and aims for 1,000 warheads by 2032, indicating deliberate escalation (Source: SIPRI 2025).
• Disarmament Stagnation: Major powers such as the U.S. and Russia, who hold 90% of global nuclear stockpiles, continue extensive modernisation rather than disarmament. Post-New START expiry in 2026, deployed warheads could rise.
• Technological Modernisation: Across all nine nuclear states, breakthroughs like Multiple Independently Targetable Re-entry Vehicles (MIRVs) and AI-driven command systems are scaling capabilities.
• India’s Role: India continues to develop delivery systems like Agni prime and submarine-launched ballistic missile technologies while slightly expanding its nuclear stockpile to 180 warheads.
• Rising Military Budgets: Global military expenditure grew by 9.4% to $2.7 trillion in 2024, with the U.S. at $997 billion and China at $314 billion.

Counterarguments and Criticisms

While the report effectively captures the quantitative trends in armament and nuclear build-ups, several critiques emerge. Structural failings in global governance, asymmetric risks of regional conflicts, and some methodological gaps in SIPRI’s data assessments are highlighted by commentators.

• Arms Control Crisis: No major nuclear powers are firmly committed to multilateral disarmament. For instance, the Non-Proliferation Treaty (NPT) lacks enforcement mechanisms for nuclear-armed signatories.
• Asymmetric Impact on Regional Security: India's modest modernisation contrasts with the rapid increases in China's arsenal (+600 warheads since 2023), potentially destabilising the South Asian deterrence dynamic. (Source: SIPRI 2025)
• Looming Proliferation: Rising discussions on nuclear acquisition in East Asia and the Middle East underline the absence of strong non-proliferation diplomacy.
• Data Transparency Issues: SIPRI relies on open-source intelligence, which faces criticism for underestimating clandestine programmes, especially in classified systems like North Korea’s arsenal.

Latest Evidence and Outlook

The 2025 report reflects stagnation in arms control efforts with looming expiration of key treaties. The post-New START world poses significant risks, as no clear successor frameworks exist to cap stockpiles. Concurrently, heightened tensions in Asia and the Middle East underscore how proliferation debates are surfacing in non-nuclear weapons states like Japan and Saudi Arabia. Regionally, the imbalance between India and China is a growing concern, especially as China's arsenal scales exponentially.

In parallel, India has selectively invested in focused deterrence technologies, such as enhancing the survivability of second-strike platforms, particularly SLBMs. This reflects a strategy of assured deterrence rather than overtly expansionist postures.

Structured Assessment

• Policy Design: Global arms control mechanisms lack enforceability, undercutting gains made post-Cold War disarmament treaties. India’s focus on defensive modernisation aligns with its no-first-use (NFU) nuclear doctrine but doesn’t offset regional strategic imbalances.
• Governance Capacity: Multilateral organisations, including the UN and IAEA, face limitations due to geopolitical rivalries. Domestically, India's nuclear command-and-control systems prioritise strategic stability.
• Behavioural/Structural Factors: Heightened mistrust undermines cooperative security frameworks, particularly in multipolar regions like South Asia. The absence of robust public pressure for disarmament globally dims prospects for change.
