Bangladesh-India relations have not experienced a genuine reset since the 2024 student uprising ended Sheikh Hasina's fifteen-year government. Three distinct but interlocked disputes have hardened into a compound impasse: a criminal extradition demand that India cannot easily satisfy or refuse, a water-sharing treaty that lapses in December 2026 without a successor, and a river-management project that China is now formally positioned to build.

The bilateral diplomatic calendar has resumed. Foreign Minister Khalilur Rahman visited New Delhi on April 8, 2026, the highest-level contact since Prime Minister Tarique Rahman's BNP took office on February 17, 2026 after its landslide February 12 election victory. But the joint statement avoided every substantive dispute. India's Ministry of External Affairs did not mention extradition, the Ganga Treaty, or Teesta in its press readout. Bangladesh's Foreign Ministry said the extradition demand was "reiterated." That asymmetry captures the relationship's structural logic: Bangladesh has grievances, India has leverage.

Extradition: A Legal Claim India Is Absorbing

The International Crimes Tribunal-1 convicted Sheikh Hasina in absentia on November 17, 2025, sentencing her to death for crimes against humanity related to the July-August 2024 crackdown, in which the United Nations estimates up to 1,400 people were killed. The same tribunal sentenced former Home Minister Asaduzzaman Khan Kamal to death. Both remain in India.

Bangladesh sent its first note verbale to the Indian MEA on December 23, 2024, under the interim Yunus government, invoking the bilateral extradition treaty signed in 2013 and ratified in 2016. A second formal note followed on November 21, 2025, citing the death sentence. India confirmed receipt of both communications; it has not responded substantively.

The extradition file creates an unusual legal geometry. The 2013 treaty obliges both sides to consider requests on specified grounds, but contains dual-criminality and political-offense exceptions. India has not invoked either publicly. Its silence is a deliberate posture: any acknowledgment risks domestic political costs with Awami League-aligned constituencies inside India, while formal rejection would give Bangladesh grounds to escalate the dispute at the international level. As of May 16, 2026, 180 days have elapsed since the ICT verdict with no Indian response.

Ganga: Thirty Years, Counting Down

The 1996 Ganga Water Sharing Treaty expires December 12, 2026. Signed by Indian Prime Minister H.D. Deve Gowda and Bangladeshi Prime Minister Sheikh Hasina on December 12, 1996, the treaty established a 30-year framework for allocating dry-season flows at the Farakka Barrage on a 10-day rotation. Article XII provides that the treaty may be renewed by mutual consent; it contains no automatic rollover.

Renewal talks opened in January 2026. The structural complication is climate-driven: Himalayan glacier retreat has reduced dry-season base flows by an estimated 15-20 percent since 1996 (Down to Earth, 2026), meaning a formulaic extension of the 1996 allocation schedule would give Bangladesh less water in absolute terms than the original treaty intended. Bangladesh wants a minimum guaranteed volume, not just a percentage-of-flow formula. India's position, as communicated by its water resources ministry, is that any new agreement must incorporate updated hydrological data and upstream storage provisions.

Neither side has publicly committed to a signed successor agreement before December 12, 2026. If the treaty lapses without replacement, both governments revert to ad hoc unilateral management of Farakka, a scenario last prevailing before the 1977 Farakka Accord.

Teesta: India Cannot Deliver, China Can

The Teesta River water-sharing agreement has been "agreed in principle" since September 2011, when the Manmohan Singh government and the Hasina government reached a draft accord allocating 42.5 percent of Teesta flows to India and 37.5 percent to Bangladesh during the dry season. West Bengal Chief Minister Mamata Banerjee withdrew her consent at the last moment, citing irrigation needs for West Bengal farmers. No Indian federal government has overridden her in the fifteen years since.

China's Power Construction Corporation entered the picture with a USD 1 billion Comprehensive Management and Restoration of Teesta River Project, proposing to dredge and rehabilitate over 102 kilometers of the Bangladeshi Teesta channel. The interim Yunus government had been considering the offer since mid-2024, and Bangladesh's Foreign Ministry sent China a Tk 67 billion loan request. On the Teesta file, Prime Minister Tarique Rahman's BNP government has now formally endorsed Chinese participation, the first explicit BNP-government endorsement, according to The Wire (April 2026).

India's calculus is structurally exposed: it cannot deliver a water-sharing treaty because of West Bengal state politics, but it objects to the alternative on national security grounds. Chinese infrastructure on the Teesta would give Beijing riverine access and sensor capacity in a corridor adjacent to the Siliguri Corridor, India's narrow land link to its northeastern states. The BNP government is using Teesta-China as a pressure point while leaving the door open to an Indian solution, a posture that requires India to either unblock the domestic political constraint or accept Chinese entry.

Border Killings: A Human Rights Ledger

The BSF killed 28 Bangladeshi nationals in 2024 according to Odhikar, down from a peak of 49 in 2020 but still representing a monthly average of more than two deaths. In the first four months of 2025, 14 further Bangladeshis were killed. Most incidents occur on cattle-smuggling and undocumented crossing routes in the Rajshahi-Chapainawabganj and Dinajpur border zones.

The Hasina government consistently avoided public confrontation with India on border killings, treating it as a secondary issue relative to trade and political ties. The BNP government has explicitly framed the killings as a human rights violation requiring treaty-level commitment on Indian border force conduct, not merely operational guidelines. India's position remains that BSF acts in response to provocation; it has resisted any formal accountability mechanism.

Trade: Asymmetry Without Remedy

Bangladesh imported $9.624 billion from India and exported $1.764 billion in FY2024-25, a trade deficit of $7.86 billion (TBS/Bangladesh Bank). Bangladesh is India's fourth-largest export destination in Asia. The deficit is structural: Bangladesh's comparative advantage in apparel and processed goods faces Indian non-tariff barriers, including sanitary and phytosanitary measures that reduce market access for Bangladeshi foods and textiles.

India cancelled its transshipment facility for Bangladeshi goods in April 2025, adding freight costs and congestion to an already asymmetric relationship. Bangladesh views this cancellation as a punitive response to Dhaka's China pivot and extradition pressure. Whether trade normalization can precede resolution of the political disputes, or must follow from them, is the central sequencing question for Bangladesh's commerce ministry.

Policy Options for the BNP Government

The BNP government's leverage is real but asymmetric. On Teesta-China, it holds a credible threat: proceed with the Chinese project unless India delivers a water-sharing deal. On extradition, it can escalate diplomatically and publicly, raising costs for India's silence. On Ganga Treaty renewal, the December 2026 deadline creates a natural pressure point that benefits Bangladesh as demandeur.

The risks of the leverage strategy are also real. India controls connectivity infrastructure, transit corridors, and upstream water flows that Bangladesh depends on. A managed deterioration of relations would cost Bangladesh more than India in the short term. The BNP government's optimal path is narrow: press hard enough on each file to extract Indian concessions, without triggering a comprehensive downgrade in relations that damages Bangladesh's trade and connectivity baseline.

The three disputes are not independent. Progress on Ganga Treaty renewal creates goodwill that reduces India's resistance on border killings. Movement on extradition, even a procedural Indian acknowledgment of the treaty timeline, could unblock trade normalization. And China's Teesta offer is most credible precisely because India's political constraints on Teesta are structural, not transient.

Conclusion

Bangladesh-India relations in 2026 are neither a reset nor a rupture. They are a structured impasse in which three unresolved disputes, each with its own deadline, are forcing both governments to calculate whether the cost of concession exceeds the cost of prolonged friction. For Bangladesh, the Ganga Treaty clock is the most urgent: December 12, 2026 is fixed, and a lapse without successor agreement would set back hydraulic diplomacy by a decade. The extradition demand will persist regardless of Indian inaction, creating a reputational accumulation that limits New Delhi's international posture on rule-of-law issues. And Teesta-China, the most geopolitically charged of the three, is the file where Bangladesh's leverage is greatest and India's constraint is most structural.
