Iran says it is suspending commitments to interim deal with U.S. as the two exchange attacks
Iran announced the suspension of its commitments under the Islamabad Memorandum of Understanding (MoU) with the United States, signed in June 2026 to end the 2026 Iran war
Iran's deputy foreign minister stated the suspension followed alleged violations of the agreement's terms, with both sides continuing military strikes
Reported strikes caused damage to infrastructure in the wider Gulf region, including a water desalination plant and an oil facility, disrupting power generation in a neighbouring Gulf state
The renewed hostilities have raised concerns over the safety of shipping lanes and energy security in the Persian Gulf, particularly around the Strait of Hormuz
Strait of Hormuz — global oil chokepoint
The Strait of Hormuz is a narrow maritime channel between Iran and Oman connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. It is the sole sea route out of the Gulf for major oil-exporting states (Saudi Arabia, Iraq, UAE, Kuwait, Qatar, Iran), making it one of the world's most critical energy chokepoints.
Key Details
- An estimated 20 million barrels per day of crude oil and oil products transited the strait in 2025
- India is the second-largest destination of Hormuz-transited crude (around 14.7%), after China, and ahead of South Korea and Japan
- India's Ministry of Petroleum and Natural Gas has stated that roughly 70% of India's crude imports now arrive via routes outside the Strait of Hormuz, reflecting diversification to around 40 supplier countries
- Route dependency differs from source diversification — even diversified crude sourcing can still rely on tankers transiting the same narrow chokepoint
The Iran-US escalation directly threatens the security of Hormuz shipping lanes; even with India's diversified sourcing, a sustained closure or insurance-driven shipping disruption at the strait would affect global crude prices and Indian import costs.
Memorandum of Understanding vs. Treaty — instruments of international law
An MoU is typically a non-binding diplomatic instrument recording mutual intent between parties, distinguished from a treaty, which creates binding obligations under international law (governed by the Vienna Convention on the Law of Treaties, 1969). The Islamabad MoU between the US and Iran was a ceasefire-and-negotiation framework rather than a comprehensive binding settlement.
Key Details
- The Islamabad MoU was concluded in mid-June 2026, mediated primarily by Pakistan with facilitation from Qatar, Saudi Arabia, Turkey and Egypt
- It provided for an immediate halt to military operations, reopening of the Strait of Hormuz to commercial shipping, gradual easing of US restrictions on Iran, and a 60-day window to negotiate a comprehensive settlement covering sanctions, Iran's nuclear programme and regional security
- Non-binding instruments such as MoUs generally lack enforcement mechanisms, making compliance dependent on continued political will of the parties
The suspension illustrates a recurring feature of non-binding ceasefire instruments in international relations — without a binding treaty framework or third-party enforcement, an MoU can unravel quickly once either side alleges non-compliance.
India's Strategic Petroleum Reserve (SPR) and energy security architecture
India maintains emergency crude oil reserves through Indian Strategic Petroleum Reserves Limited (ISPRL), a Special Purpose Vehicle under the Ministry of Petroleum and Natural Gas, set up to cushion the economy against global supply shocks of the kind a Hormuz disruption could cause.
Key Details
- ISPRL operates underground strategic storage caverns at Visakhapatnam (1.33 MMT), Mangaluru (1.5 MMT) and Padur (2.5 MMT), totalling around 5.33 MMT (about 9.5 days of consumption)
- Combined with refiners' own crude storage (around 64.5 days), India's overall crude storage cover is estimated at roughly 74 days
- A second phase of expansion includes new caverns planned at Chandikhole (Odisha) and Bikaner (Rajasthan)
Sustained Gulf hostilities test the adequacy of India's strategic reserve buffer and its diversification strategy away from Hormuz-dependent routes, both instituted precisely to manage risks of the kind now materialising.
- Islamabad MoU signed: mid-June 2026, mediated by Pakistan (with Qatar, Saudi Arabia, Turkey, Egypt facilitating)
- MoU provided for a 60-day negotiation window on sanctions, nuclear programme and regional security issues
- Strait of Hormuz oil flow (2025): ~20 million barrels/day
- India's share of Hormuz-transited crude: ~14.7% (second-largest destination after China)
- Share of India's crude imports now routed outside the Strait of Hormuz: ~70% (Petroleum Ministry, 2026)
- India's ISPRL strategic reserve: ~5.33 MMT / ~9.5 days of consumption across Visakhapatnam, Mangaluru and Padur
