Sensex, Nifty Set for Lower Open as Crude Oil Tops $90 on US-Iran Tensions

Indian equity benchmarks looked set for a weak start on Tuesday, August 18, with GIFT Nifty futures pointing to a lower open after crude oil prices climbed back above the $90-a-barrel mark overnight. The move came as fresh uncertainty over the status of the US-Iran ceasefire rattled global energy markets, adding another headwind to a domestic market already on a losing streak.

GIFT Nifty Signals Weak Start

NIFTY futures trading at GIFT City in Gandhinagar slipped around 102 points to near 24,290 in early trade, indicating that the Nifty 50 could open well below Monday's closing level. The pressure followed a broadly negative tone across Asian markets, with Japan's Nikkei down more than 1% and Hong Kong's Hang Seng and China's Shanghai Composite also trading lower as investors reacted to the overnight spike in oil prices.

Fifth Straight Losing Session for Nifty

Tuesday's expected weak open would extend a difficult run for Indian equities. On Monday, the Sensex ended 281 points lower at 77,728, while the Nifty 50 slipped 78 points to close at 24,288, marking its fifth consecutive session in the red. The sustained selling has come even as domestic fundamentals remain largely intact, underscoring how sensitive sentiment has become to global cues, particularly the trajectory of crude oil prices.

Crude Oil Jumps on Renewed Hormuz Uncertainty

Behind the latest bout of nervousness is a fresh escalation in the standoff between Washington and Tehran over the Strait of Hormuz. A memorandum of understanding aimed at easing the crisis lapsed without a resolution, and Iranian officials signalled they were not interested in extending talks on the current terms, saying negotiations had effectively stalled. That has kept traffic through the strait well below normal levels and left oil markets on edge.

International benchmark Brent crude pushed past $90 a barrel in the wake of the news, while US crude also moved firmly higher, reflecting concerns that a prolonged disruption to shipping through one of the world's most important energy corridors could tighten global supply further. For India, which imports the vast majority of its crude needs, a sustained rise in oil prices is a particularly sensitive signal, since it feeds directly into the country's import bill, the rupee, and inflation expectations.

What It Means for Indian Markets

Higher crude prices tend to weigh on Indian equities through multiple channels: they raise input costs for oil marketing companies and aviation stocks, add pressure to the current account deficit, and complicate the inflation outlook at a time when the Reserve Bank of India has been trying to balance growth support with price stability. Rate-sensitive sectors and oil-import-heavy names are likely to be in focus as trading gets under way, while investors will also be watching for any signs of a de-escalation in the Hormuz standoff that could offer relief.

With global crude benchmarks now hovering near multi-month highs and the geopolitical backdrop still fluid, market participants are likely to stay cautious in the near term. Traders will be tracking further developments out of Washington and Tehran through the day, alongside any commentary from Indian policymakers on the potential impact of sustained high oil prices on the broader economy.
