Brent crude surges past $100 as US-Iran tensions rattle global markets

Brent crude jumped above $100 a barrel for the first time since late May on Thursday, surging nearly 12% this week as escalating US-Iran military strikes fueled fears of supply disruptions across the Gulf region. The benchmark was trading at $98.08 per barrel, while West Texas Intermediate crude rose to $89.63 per barrel, as geopolitical risk premiums overwhelmed what analysts describe as a fundamentally well-supplied market.

"The key question for markets is whether the recent escalation represents a temporary bout of geopolitical posturing or the start of a more prolonged conflict between the US and Iran," said Mitesh Jain, head of broking at Sanctum Wealth. "While markets are likely to look through a temporary spike in oil prices, a sustained rise above $100 per barrel would pose a meaningful risk to growth, inflation and market performance."

The oil surge triggered a broad risk-off rotation across asset classes. India's Nifty 50 fell 0.53% to 23,869.60, while the BSE Sensex shed 0.47% to 76,391.39 — both logging their fourth straight session of losses, the longest declining streak in seven weeks. Bitcoin dropped below $65,000, dragging the broader crypto market lower as traders unwound risk positions. The European Central Bank left rates unchanged on Thursday, with policymakers citing elevated energy costs as a fresh complication for the inflation outlook.

For India, the world's third-largest crude importer, the price spike reignites familiar macroeconomic vulnerabilities. A $10-per-barrel sustained increase in oil prices can widen the current account deficit by roughly 0.4% of GDP and add 30 to 40 basis points to consumer inflation, according to historical RBI estimates. The central bank's latest monthly bulletin noted that India's crude oil basket had eased to $75.6 per barrel in July from a peak of $114.5 in April, but the current trajectory threatens to reverse that progress. Domestic retail fuel prices have so far remained unchanged, with petrol at 108.7 rupees per liter and diesel at 98.1 rupees per liter.

Why $100 oil may not last — but the damage is already priced in

Market participants broadly view the current price surge as a geopolitical risk premium rather than a structural supply deficit. OPEC's spare capacity remains ample, US production is near record levels, and aggressive competition among oil-exporting nations — including discounted Russian and Iranian crude — is expected to cap further upside. The last time Brent traded above $100 for a sustained period was in 2022 following Russia's invasion of Ukraine, when prices averaged $99 per barrel for the year before retreating as central bank tightening curbed demand.

The bigger risk for policymakers is a prolonged conflict scenario. If US-Iran hostilities disrupt shipping through the Strait of Hormuz — through which about 20% of the world's oil passes — prices could spike well above $100 and remain elevated for months. Such an outcome would complicate inflation management for central banks globally, weaken emerging-market currencies including the rupee, and force import-dependent economies to burn through foreign exchange reserves at an accelerated pace.

For crypto markets, the risk-off rotation has been swift. Bitcoin's break below $65,000 — a level that had held as support since mid-June — opens the door to further downside toward the $60,000 zone, according to technical analysts. Altcoins have suffered proportionally larger losses, with the broader crypto market capitalization declining as traders reduce exposure to high-beta assets in favor of havens like gold, which has also rallied on the geopolitical uncertainty.
