The Indus Waters Treaty (IWT) is a landmark water-sharing agreement between India and Pakistan that has played a crucial role in managing one of the most sensitive resources in South Asia—the waters of the Indus River system. Signed in 1960 with the help of the World Bank, the treaty allocates control and use of the six major rivers flowing through both countries. Despite multiple conflicts and political tensions over the decades, the treaty has largely survived as a rare example of cooperation between the two neighbors. However, recent developments have put the treaty under serious strain, threatening water security and regional stability.
The Indus Waters Treaty was signed on September 19, 1960, in Karachi by the leaders of India and Pakistan. The agreement was brokered by the World Bank, also known as the International Bank for Reconstruction and Development, which played a key role in mediating terms acceptable to both parties. The treaty divides the Indus River system into two parts: the eastern rivers—Ravi, Beas, and Sutlej—were allocated to India, while the western rivers—Indus, Jhelum, and Chenab—were allocated to Pakistan. India was granted exclusive rights over the eastern rivers, while Pakistan was given control over the western rivers. Under the treaty, India retained limited, non-consumptive use of the western rivers for purposes like irrigation, transport, and hydroelectric power, but the overall control and flow were primarily to Pakistan.
This water-sharing agreement is considered one of the most successful international water treaties, surviving three wars between India and Pakistan—in 1965, 1971, and 1999—and various political crises. Millions of people, especially in Pakistan, depend on the western rivers for drinking water, agriculture, and other daily uses. The treaty established the Permanent Indus Commission, a bilateral body consisting of one commissioner from each country. The commission meets regularly to exchange information, monitor river flows, and resolve disputes. If disagreements cannot be resolved bilaterally, the treaty provides for involvement of neutral experts or arbitration through a court, offering a legal mechanism to address conflicts.
Despite its success, the Indus Waters Treaty has faced increasing challenges in recent years. India has expressed concerns that Pakistan has not cooperated fully on hydropower projects and other river management issues. After a terror attack in Kashmir’s Pahalgam in early 2025, India suspended its participation in the treaty, accusing Pakistan-based groups of supporting terrorism and using the treaty as leverage. This move marked the first time India took such a significant step to halt the long-standing water-sharing arrangement. Pakistan responded by highlighting immediate water shortages, with reports showing drastically reduced flows in the Chenab River, which is vital for Pakistan’s irrigation and farming.
India’s decision to suspend the treaty has raised fears of a worsening water crisis in Pakistan’s Punjab and Sindh provinces. Farmers and communities reliant on the river’s water face uncertainty about their future crops and water supply. Pakistani officials have accused India of violating the treaty by cutting off water supplies without warning. The Permanent Indus Commission, which usually manages such issues through dialogue, is now under unprecedented stress. The United States has offered to mediate between the two countries, hoping to bring both sides back to the negotiating table. However, India remains firm on its stance, tying the treaty’s future to broader security and political concerns.
The Indus Waters Treaty represents more than just an agreement on water. It symbolizes the fragile relationship between India and Pakistan, where cooperation is often interrupted by conflict and mistrust. While the treaty has helped prevent water-related disputes from escalating into larger conflicts for decades, recent political tensions and acts of violence threaten to undo years of progress. The World Bank, which helped broker the treaty, continues to advocate for peaceful resolution but has limited power to enforce compliance.
Experts warn that without trust and open communication, water scarcity and disputes could worsen. For millions living along the Indus River system, the treaty’s stability is directly linked to their livelihood and survival. The future of the Indus Waters Treaty will depend on whether India and Pakistan can separate water cooperation from political disagreements and rebuild the framework of trust that has allowed this agreement to endure for more than six decades.
