Hormuz Crisis Deepens: Oil Production Shocks Ripple Through Asian Markets

The war in Iran has upended the global oil market in ways that will reverberate through Asian economies for months. The closure of the Strait of Hormuz—the narrow waterway through which roughly a third of the world's seaborne oil passes—has forced producers to shut down wells they cannot operate or export from. The result is staggering: 15 million barrels of oil per day have gone offline, according to analysis from Wood Mackenzie. That gap is so large it has prompted speculation that crude could touch $200 a barrel, a price not seen in the modern era.

For countries like India, South Korea, Japan, and others across Asia that depend heavily on Gulf crude, the shock is immediate and severe. Prices are rising. Export restrictions are tightening. The downstream infrastructure that turns raw oil into fuel, plastics, and chemicals is straining under the weight of disruption. Indian oil majors—Indian Oil, Bharat Petroleum, and Hindustan Petroleum—are already under pressure from global rating agencies, which have flagged concerns about their margins and credit risk as imported energy costs climb and domestic fuel prices remain constrained by government policy.

The crisis extends beyond the energy sector itself. India's cement industry, which relies on oil and gas for production, faces fuel costs that have jumped 39 percent. Elara Capital predicts a significant hit to profits in the second quarter of the next fiscal year and suggests a 1.8 percent price hike to offset the damage—though past attempts at raising prices have largely failed. Companies with access to renewable energy or plants near coal mines may have a temporary advantage, but the broader industry is bracing for a squeeze.

The financial markets are reacting with visible anxiety. India's stock indices have fallen sharply, with the Sensex dropping 1,100 points and the Nifty plunging as investors weigh the geopolitical risk and the prospect of sustained high oil prices. Overnight index swap rates have spiked, with the one-year OIS rising 24 basis points to 5.72 percent and the five-year OIS jumping 28 basis points to 6.27 percent. The rupee, which had weakened to record lows, has recovered slightly to 91.80 against the dollar, but dealers expect continued pressure and forecast it will trade between 92 and 92.5 by month's end.

The Indian government has moved to cushion the blow. It has proposed a 1 lakh crore Economic Stabilisation Fund to absorb sudden economic shocks, with additional allocations of 23,641 crore for food subsidies and 19,230 crore for fertiliser support. The Directorate General of Shipping has also advised companies to avoid predatory pricing in the shipping sector, where costs have spiked due to the conflict, and has called for clear communication of charges to exporters and importers. The government is exploring insurance support and other schemes to help exporters navigate the higher costs.

What makes the crisis particularly difficult to manage is the timeline for recovery. Even if the conflict ended today, the damage would not reverse quickly. Shipping routes would need weeks to stabilize. Oil production would take months to return to normal levels. Wells that have been shut down cannot simply be switched back on; they require careful restart procedures. The infrastructure that moves oil from the wellhead to refineries and then to markets operates on long lead times. Until those systems normalize, Asian economies will absorb the cost of scarcity and the uncertainty of not knowing when relief will arrive.
