Signal India suspends the 65-year-old Indus Waters Treaty

Summary

Eurasia Group reports that the Indus Waters Treaty endured for 65 years and through three wars between India and Pakistan. In April 2025, after the Pahalgam terrorist attack, India suspended the treaty and stopped providing hydrological data to Pakistan. The suspension has continued despite a ceasefire brokered by the United States in May, and India wants to keep it as a threat. The report argues that the case shows how quickly water can be turned into a weapon once wider tensions flare. Because both countries are nuclear-armed, this raises the stakes of any future crisis.
