The suspension of the IWT poses severe risks to Pakistan's water security, as the Indus River Basin supports over 200 million people in Pakistan and 100 million in northwestern India. The lack of hydrological data sharing undermines flood preparedness, as evidenced during the 2025 floods. Furthermore, India's increased hydropower development on the western rivers could potentially alter water flows, exacerbating tensions between the two nations. The situation has also heightened security concerns, with both countries engaging in escalatory rhetoric. Pakistan has warned that any attempt to divert water allocated under the treaty could be considered an act of war, further straining relations between the nuclear-armed neighbours.
