GS-II: India and its neighbourhood—relations; bilateral agreements involving India or affecting India’s interests.
Introduction
India decided to hold the Indus Waters Treaty in abeyance since 23 April 2025. This decision was followed by competing legal proceedings in 2026. This entire situation has transformed a long-standing water arrangement. It now serves as a critical test for **treaty durability**, **national security**, and **transboundary cooperation**. The issue now concerns how binding institutions respond when political trust collapses.
Historical Evolution
The Treaty's history is presented in chronological order. It covers events from the Partition's impact on irrigation to the current institutional breakdown.
1947 — Partition divided an integrated Indus irrigation network
The new borders placed upstream headworks in India. Several canal commands ended up in Pakistan. Temporary Inter-Dominion arrangements managed immediate water supplies. However, these arrangements did not settle the long-term water allocation.
1951–1960 — World Bank-assisted negotiations pursued a functional river division
World Bank President Eugene Black encouraged an engineering-based settlement. This happened after direct negotiations between the countries stalled. International finance supported the construction of replacement canals and other works. These were needed to make the eventual water allocation operational.
1960 — India and Pakistan signed the Treaty at Karachi
Prime Minister Jawaharlal Nehru and President Mohammad Ayub Khan signed the Treaty on 19 September 1960. The World Bank also became a signatory for specific purposes.
“The amicable and friendly resolution of this difficult issue with multilateral assistance is a striking example of the value of international cooperation and good will.” — Dwight D. Eisenhower, 19 September 1960

1965–2024 — Technical cooperation endured repeated political and military crises
The Treaty's framework continued to function. This was despite the 1965 and 1971 wars, the Kargil conflict, and various diplomatic breakdowns. Clear entitlements, specific engineering rules, and a standing commission helped. These factors protected limited cooperation from wider conflicts.
2025–2026 — Abeyance and competing proceedings produced an institutional rupture
India held the Treaty in abeyance starting 23 April 2025. This was until Pakistan credibly and irrevocably ends its support for cross-border terrorism. On 31 August 2026, a Court of Arbitration ruled that the Treaty remained in force. However, India rejected its jurisdiction. India also maintained its position that the Treaty was in abeyance.

Treaty Architecture and Institutions
The treaty's framework encompasses substantive river rights, cooperation, adjudication, and formal modification.
River Allocation and Permitted Uses
- Eastern Rivers: The Ravi, Beas, and Sutlej rivers are allocated to India.
- Western Rivers: The Indus, Jhelum, and Chenab rivers are primarily allocated to Pakistan.
- Permitted Indian uses: India is permitted to use the Western Rivers for domestic, non-consumptive, specified irrigation, and run-of-river hydropower purposes.
Cooperation and Information Exchange
- Permanent Indus Commission: The Permanent Indus Commission consists of one commissioner from each country. This commission manages data, conducts inspections, fosters cooperation, and addresses questions.
The World Bank performs limited procedural—not adjudicatory—functions
The Bank can appoint individuals to specific roles when formally requested, but it does not rule on the merits of a case. An ad hoc Court of Arbitration resolves disputes, while the Permanent Court of Arbitration offers registry and secretariat services. World Bank fact sheet
Dispute-Settlement Sequence
- Questions: Initially, the Permanent Indus Commission examines issues related to implementation or interpretation.
- Differences: Certain technical matters may be referred to a Neutral Expert for a binding decision within their defined authority.
- Disputes: Legal disputes can be referred to an ad hoc Court of Arbitration, as per Article IX and Annexure G.
Modification under Article XII
- Mutual amendment: The Treaty can be modified through a duly ratified treaty between both governments.
Pillars of Cooperation
Three key pillars demonstrate the Treaty’s long-term strength. The mechanisms and specific cases discussed are categorised under the pillar they support.
Allocation and Developmental Certainty
Territorial allocation reduces recurring bargaining over seasonal river flows
Defined water entitlements provide both states with a predictable basis for irrigation and infrastructure planning. This arrangement lessens, though it does not completely remove, disagreements over permissible uses and project designs.
Run-of-river hydropower balances Indian development with downstream safeguards
India can develop eligible projects on Western Rivers. These projects must adhere to specific design and operational constraints. In the 2013 Kishenganga arbitration, the Court allowed the project. However, it mandated a minimum downstream water flow. This demonstrated a balance between upstream development and downstream protection.
Continuous Institutional Cooperation
The Permanent Indus Commission preserves technical dialogue during political crises
Commission meetings, inspections, and routine exchanges maintained a professional channel. This continued even during several diplomatic breakdowns. This institutional lesson shows that regular technical contact can contain disputes. This is true even when it cannot resolve the broader conflict.
- Hydrological data exchange: Shared information supports planning, flood warning, and scrutiny of upstream projects.
Dispute Containment
Graduated procedures keep technical differences below the political threshold
Issues are first discussed bilaterally. Defined differences then move to specialised expert review. Legal disputes may proceed to arbitration. This structured escalation prevents every engineering disagreement from becoming a diplomatic or military crisis.
Baglihar (2007) validated specialised expert determination for design disputes
A Neutral Expert examined design questions for the Baglihar run-of-river project. The expert then issued a binding technical determination. This case highlights the value of engineering expertise. This is particularly true when jurisdiction and sequencing are clear.
Areas of Friction
These areas of friction are grouped into three categories: project and procedural issues, security and legal conflicts, and structural gaps from the climate era.
Project and Procedural Disputes
- Kishenganga and Ratle: Pakistan disputes the design features of these projects. India, however, asserts that both run-of-river projects adhere to its Treaty rights.
Parallel dispute routes risk contradictory decisions on the same technical issues
In 2016, Pakistan sought arbitration, while India requested a Neutral Expert. The World Bank initially paused these appointments. However, it resumed both in 2022 after consultations failed. This situation highlights the need for an agreed sequencing rule and a clear deadline. World Bank fact sheet
Security and Legal Conflict
India links normal Treaty cooperation to an end to cross-border terrorism
The decision to hold the Treaty in abeyance redefines water cooperation within the framework of sovereign security obligations. It also raises an unresolved question: how does treaty performance work when one party claims a fundamental breakdown of political trust?
The 2026 arbitral position and India’s jurisdictional rejection remain opposed
The Court concluded that a unilateral abeyance did not end Treaty obligations. However, India declared the body illegally constituted and without jurisdiction. For a balanced perspective, the arbitral award, India’s objection, and the practical fact of its non-participation must be stated separately.
Ratle interim measures intensified the conflict over institutional competence
The Court imposed restrictions on specific construction until 90 days after the Neutral Expert’s final decision, which is expected in July 2027. India, however, rejected that these directions had any applicability to its projects. PCA case record, 31 August 2026
Climate-era Structural Gaps
Twentieth-century allocation rules inadequately address accelerating hydrological variability
Changes in glaciers, extreme floods, droughts, and sediment variability complicate existing fixed engineering assumptions. The Treaty does not provide a comprehensive framework for climate adaptation, groundwater management, water quality, or basin ecology.
- Infrastructure constraint: Geographical limitations and insufficient storage or canal capacity restrict any immediate large-scale diversion of Western River flows.
India’s Strategic Interests
India’s strategic interests span security, sovereign rights, development, legal credibility, and regional stability.
Security and Sovereignty
- Counter-terrorism signalling: Cooperation must acknowledge sustained cross-border terrorism.
- Negotiating autonomy: India aims for procedural arrangements that avoid legitimising institutions whose jurisdiction it rejects.
Development and Water Use
- Allocated rights: India must efficiently use its rights over the Eastern Rivers and its permitted entitlements from the Western Rivers.
- Energy security: Treaty-compliant hydropower can support renewable electricity and promote development in Jammu and Kashmir.
- Disaster resilience: Reliable basin data improves flood warning, reservoir management, and emergency response.
Legal Credibility and Regional Stability
A calibrated strategy must balance coercive signalling with long-term predictability
Applying maximum pressure may lead to reputational and humanitarian costs. Conversely, unconditional technical normalcy could weaken India’s security message. Essential safety information can be insulated. However, negotiable institutional benefits must remain linked to verified security conditions.
- Responsible-riparian reputation: Precise treaty reasoning strengthens India’s position across other Himalayan river systems.
- Regional stability: Sudden water uncertainty can escalate food, migration, humanitarian, and military risks.
Way Forward
The way forward begins with reducing immediate risks. It then moves to institutional reform and building stronger domestic water capabilities.
Immediate Safety and Communication
- Protect essential data: Communicate essential flood-warning and dam-safety information. This communication should be narrowly defined and based on reciprocal humanitarian grounds.
- Controlled dialogue: Use an empowered technical backchannel for dialogue. This channel should not prejudice either side's stated legal position.
Treaty and Institutional Reform
Clarify the sequence of Neutral Expert and arbitral proceedings
A supplementary protocol should prevent simultaneous proceedings over substantially identical technical questions. Defined consultation periods and referral thresholds would reduce forum conflict.
Use Article XII to negotiate climate-era and procedural modernisation
A ratified protocol could address issues like hydrological variability, sediment, dam safety, technology, and objection timelines. This would also preserve clear water allocations. The Parliamentary Standing Committee on Water Resources submitted its 12th Report in 2021. This report recommended diplomatic renegotiation. It also suggested an institutional or legislative framework to address climate impacts and other uncovered challenges. PRS summary of the Committee report
- Joint climate science: Share data on snow, glaciers, and seasonal river flows. This should be done through transparent models and with neutral scientific support.
- Project transparency: Exchange timely designs for hydropower projects. For contested works, use independent technical review.
Domestic Capability and Water Efficiency
- Exercise rights credibly: Credibly exercise water rights. Complete viable projects for Eastern River use and Treaty-compliant hydropower. Do this without making exaggerated claims about water diversion.
- Reduce basin stress: Improve irrigation efficiency, aquifer management, and crop choices. Also, enhance urban water governance. These steps will help reduce basin stress.
- Design de-escalation: Combine verifiable security commitments with procedural reform. Also, gradually restore technical cooperation. This will help design de-escalation.
