US-Iran War Restarts, Oil Surges, and Markets Reel

Strait of Hormuz risk is not merely theoretical: Iran has previously mined the strait and seized tankers, and the attack on three ships this week shows Tehran is willing to use maritime warfare as leverage. The US ending its sanctions waiver on Iranian energy removes a significant source of supply that several Asian buyers — including India — had quietly resumed tapping. Washington's decision to reimpose full sanctions simultaneously tightens global supply and raises the cost of any country that continues to buy Iranian crude.

For India, the impact is acute and multi-channel. India had resumed Iranian oil imports in April and May 2026 (The Hindu reports Iran and Venezuela purchases restarted), and that supply is now at risk of sanctions exposure. Russia already supplies over 40% of India's crude imports, limiting diversification options. The rupee fell 59 paise to close at 95.55 against the dollar on Wednesday — a sharp single-session move driven by higher oil (which widens India's current-account deficit) and a stronger dollar. The Sensex/Nifty felt the pressure too, though India VIX fell 9% on Thursday as markets partially stabilised; the broader risk is that a sustained oil price above $80 stokes domestic inflation, complicates the RBI's rate-cut path, and pressures the fiscal deficit through higher fuel subsidies.

India's oil import diversification strategy has been quietly unravelling: Russia supplies over 40% of imports at a premium (The Hindu), Iran was being tapped again for discounted barrels, and now sanctions risk closes that door. The Australia uranium deal announced today (India and Australia finalised uranium export administrative arrangements) offers a long-term hedge via nuclear energy, but provides no near-term relief for the oil bill. The RBI's task is complicated: June CPI is forecast to have risen to 4.3% — above the 4% target — from 3.93% in May, meaning the central bank faces stagflationary pressure if oil stays elevated.

The IPO market is a bellwether for broader capital-market confidence. India's equity rally over the past year has been partly funded by FPI inflows attracted by strong growth and falling inflation; a sustained oil shock reverses both narratives simultaneously. Wholesale price inflation eased marginally in June, suggesting some pipeline relief, but the oil spike post-ceasefire collapse could reverse that quickly. For the Nifty, the key watch is whether FPIs turn net sellers — a sustained sell-off would widen the rupee's losses and create a feedback loop of higher import costs and tighter financial conditions.

The two-speed Chinese economy — strong exports, weak consumption — has become a fault line in global trade politics. Trading partners, including the EU and US, argue that China's export machine is flooding world markets with cheap goods subsidised by suppressed domestic demand, a dynamic that underpins ongoing trade friction and tariff threats. For commodity exporters, a China that buys raw materials but exports finished goods cheaply is a mixed blessing: it supports resource prices but undercuts manufacturing sectors elsewhere.

For India, the China inflation divergence cuts both ways. Cheap Chinese manufactured exports keep a lid on India's core goods inflation, helping the RBI. But surging Chinese PPI — if it eventually feeds into export prices — could reverse that disinflationary tailwind. More immediately, China's continued strong demand for oil and commodities (reflected in high PPI) adds to the global price pressure that is already squeezing India's import bill in the wake of the Iran escalation.

Nuclear energy is central to India's plan to meet its net-zero commitments while sustaining 7%+ GDP growth. India currently has 22 operational reactors and plans to triple nuclear capacity by 2032; securing uranium from a stable, democratic supplier like Australia reduces the geopolitical risk embedded in its energy mix. The timing — announced on the same day that Gulf oil supply routes face renewed disruption — underscores the strategic logic of diversification.

The broader supply-chain cooperation element of the deal targets critical minerals and clean-energy components, areas where Australia is a major producer and India is a major consumer. For Indian markets, the deal is a medium-term positive for the power and capital-goods sectors. It also reinforces the India-Australia Economic Cooperation and Trade Agreement (ECTA) framework, which has been expanding bilateral trade in goods and services since 2022.
