Overview
The SIPRI Yearbook 2026 records a historic rise in military expenditure. Global spend reached $2.9 trillion in 2025 – 2.5 % of world GDP – marking the eleventh consecutive year of increase.
Global Military Spending Record
- United States: $954 billion (≈32.9 % of world total, down 7.5 % YoY)
- China: $336 billion (12 % of world total)
- Russia: $190 billion (6.6 %)
- Germany: $114 billion (3.9 %)
- India: $92.1 billion (3.2 %, up 8.9 % YoY)
India’s Defence Outlay
India’s spend of $92.1 billion in 2025 places it as the fifth‑largest spender, overtaking the United Kingdom for the first time. The rise reflects higher procurement, modernisation of platforms and increased personnel costs.
Arms Transfers and India’s Position
International arms transfers hit a post‑Cold‑War peak in 2021‑25, up 9.2 % from 2016‑20. The United States, France, Russia, Germany and China together account for 70 % of exports. India emerged as the second‑largest importer, representing 8.2 % of global imports.
Nuclear Arsenal Updates
According to SIPRI, the world possessed 12,187 nuclear warheads in January 2026. The top five holders remain Russia (5,420) and the United States (5,042). India’s stockpile stands at ≈190 warheads, a modest increase from the previous year, while Pakistan holds about 170.
Key Flashpoint – India‑Pakistan Cyber Conflict
SIPRI flagged the May 7‑10, 2025 India‑Pakistan clash as a dangerous flashpoint. Both sides launched conventional strikes on air‑ and missile bases, some with nuclear‑related roles, and for the first time employed open cyber‑attacks as part of an armed conflict. Despite the escalation, diplomatic channels prevented a nuclear exchange.
Emerging Destabilising Trends
- Nuclear‑conventional entanglement creates a “grey area” that could trigger unintended nuclear use.
- MIRV capability demonstrated by India’s advanced Agni test in May 2026.
- Growth of submarine‑based nuclear weapons among more states adds strategic uncertainty.
International Nuclear Governance
Four major frameworks regulate nuclear weapons:
- NPT: India has not signed.
- Treaty on the Prohibition of Nuclear Weapons (TPNW, 2017): India, China, Pakistan and the USA are non‑signatories.
- Comprehensive Nuclear‑Test‑Ban Treaty (CTBT, 1996): Still not in force; India has not signed.
- New START: Expired in February 2026, leaving no binding limits on the two superpowers.
Exam Relevance
- Understanding trends in global defence spending helps answer GS 3 questions on security and economy.
- Data on India’s rank and spend is directly testable in current affairs and comparative analysis.
- Knowledge of arms‑transfer dynamics and India’s import share is useful for questions on strategic autonomy.
- Insights into nuclear doctrines, MIRV tests and cyber‑warfare align with GS 2 (Polity) and GS 4 (Ethics) topics on security and technology.
- Familiarity with the status of NPT, TPNW, CTBT and New START is essential for treaty‑based questions.
Way Forward
India should continue modernising its forces while enhancing transparency in arms imports. Strengthening diplomatic engagement on nuclear risk‑reduction, especially around MIRV deployment and cyber‑escalation, will support global stability. Participation in multilateral forums can help shape future arms‑control norms.
