SIPRI Yearbook 2026: India 5th Largest Military Spender with USD 92.1 Billion; Nuclear Arsenal Grows to 190 Warheads

Detailed Summary

The Stockholm International Peace Research Institute (SIPRI) released its SIPRI Yearbook 2026 in June 2026, providing a comprehensive assessment of global armaments, disarmament, and international security trends. According to the report, India was the world's 5th largest military spender in 2025, with defence expenditure reaching USD 92.1 billion — an increase of 8.9% compared to the previous year. The top military spenders globally were: 1st — United States (USD 954 billion), 2nd — China (USD 336 billion), 3rd — Russia (USD 190 billion), 4th — Germany, and 5th — India. Global military expenditure rose for the 11th consecutive year in 2025, reaching USD 2.9 trillion — the highest level ever recorded by SIPRI.

On the nuclear front, SIPRI estimated India's nuclear arsenal at approximately 190 warheads as of January 2026, compared to 180 in 2025. Of these, 12 warheads were deployed and 178 were in reserve or storage. India's modernisation programme is increasingly focused on long-range weapons capable of reaching targets across China, while maintaining strategic deterrence against Pakistan. The report also described the India-Pakistan military confrontation of May 2025 (Operation Sindoor) as "an unusually severe military crisis" between two nuclear-armed neighbours, noting that both countries took steps to avoid nuclear escalation. Pakistan's estimated stockpile stood at 170 warheads, while China held 620.

Historical Background

SIPRI was established in 1966 in Stockholm, Sweden, as an independent international research institute dedicated to research into conflict, armaments, arms control, and disarmament. It publishes the SIPRI Yearbook annually. The institute is widely regarded as one of the most credible global sources for data on military expenditure, nuclear arsenals, arms transfers, and security trends. India has consistently been among the world's top military spenders due to its large standing army, ongoing modernisation programmes, border security requirements (with China and Pakistan), and strategic ambitions as a major global power.

Why Important for TNPSC

Defence and security-related questions, India's position in global military rankings, and reports by international organizations like SIPRI are covered in TNPSC Group 1 and Group 2 General Studies papers. The SIPRI Yearbook is one of the key international reports tested. Questions about India's nuclear doctrine, No-First-Use (NFU) policy, and nuclear warhead counts are relevant to Defence and International Relations sections of the TNPSC syllabus.
