Escalating US-Iran Conflict Pushes Brent Above $90

Brent crude climbs above $90 as Hormuz disruptions and escalating US-Iran conflict revive fears of global supply shocks.

Oil prices surged sharply on Monday, propelled by escalating military confrontations between the United States and Iran, pushing the Brent crude benchmark above the psychologically significant $90 per barrel level for the first time since mid-June. Brent crude futures climbed $2.69, or 3.05 percent, to $90.79 in late Asian trading hours, building on last week’s impressive 15.9 percent gain — the strongest weekly performance since April. Similarly, US West Texas Intermediate (WTI) crude rose $2.19, or 2.65 percent, to $84.68, reaching its highest level since June 12 after advancing 15.5 percent over the previous week.
This renewed rally depicts the market’s acute sensitivity to developments in the Persian Gulf, where the Strait of Hormuz serves as a vital artery for global energy flows, typically handling approximately one-fifth of the world’s oil trade. The latest spike comes as hopes for a stable ceasefire have rapidly diminished amid a series of tit-for-tat actions that have expanded from targeted military sites to critical infrastructure, including ports, bridges, and energy facilities.
Over the weekend and into Monday, the United States carried out its ninth consecutive night of airstrikes against Iranian targets. US Central Command described the operations as necessary to degrade Iranian military capabilities threatening commercial vessels and civilian mariners in the Strait of Hormuz. In response, Iranian forces launched strikes on US allies, with Kuwait and Bahrain reporting attacks, including significant damage to a Kuwait Petroleum Corp. oil facility. Reports also emerged of a vessel on fire northwest of Oman’s Kumzar, further heightening maritime security concerns in the region.
Shipping data highlights the immediate operational impact. According to LSEG figures, only four vessels transited the Strait of Hormuz on Sunday, down from eight the day before. At least three oil products tankers and one Very Large Crude Carrier have entered the strait since Friday to load oil, but overall activity has been curtailed by mutual enforcement actions. The US has imposed a naval blockade on Iranian ports, while Iran has targeted vessels it accuses of violating its navigation rules, including those using what Tehran deems “unsafe routes.” These disruptions threaten the efficient “shuttle run” operations relied upon by Persian Gulf producers to move crude to export terminals.
The conflict’s escalation has caught markets with limited defensive buffers. Analysts at JPMorgan Chase & Co. and Barclays have drawn attention to historically tight global oil inventories outside China, which are at their lowest levels in recent years. Barclays analyst Amarpreet Singh cautioned in a note that “the coming days and weeks will provide a clearer picture of the sustainable level of oil exports from the region under renewed dual blockades,” warning that current pricing may underestimate the potential fallout for inventories.
Beyond the immediate supply risks, the situation carries broader economic and geopolitical ramifications. Higher energy costs could exacerbate inflationary pressures in oil-importing economies, including India, where rising crude prices directly influence retail fuel costs, the current account balance, and overall macroeconomic stability. Downstream sectors such as transportation, petrochemicals, refining, and aviation stand to face increased input costs, potentially feeding through to consumer prices and corporate margins.
Equity markets reflected measured caution amid the oil rally. US stock-index futures were little changed to modestly softer late Sunday, as participants balanced geopolitical tensions against anticipation of a pivotal earnings week. Major technology companies, including Alphabet and Tesla, are scheduled to report results, alongside other bellwethers such as General Motors, AT&T, Intel, and Verizon. The performance of these firms, particularly the so-called Magnificent Seven, will be closely watched for signals on the health of the broader bull market.
This latest chapter in US-Iran hostilities marks a reversal of the relative calm that followed earlier ceasefire understandings. Prices had moderated in recent weeks as shipping through the Strait partially recovered, but fresh strikes and declarations from both sides — including Iran’s effective withdrawal from prior agreements — have reintroduced a substantial geopolitical risk premium. The International Energy Agency has previously highlighted that prolonged disruptions in the Hormuz chokepoint could deliver a meaningful blow to global economic growth by constraining energy supplies at a time when inventories are already strained.
From here, the trajectory of oil prices will hinge on several factors: the duration and intensity of military operations, the effectiveness of any backchannel diplomatic efforts, actual volumes of oil moving through the Strait, and responses from other major producers. While some market participants continue to hope for a swift de-escalation, the current pattern of nightly strikes and retaliatory actions suggests a more protracted period of uncertainty. In the near term, the balance of risks remains tilted toward higher prices, with potential for further volatility as fresh headlines emerge from the region.
Market participants, policymakers, and industry stakeholders will be monitoring real-time shipping data, official communiqués from US Central Command and Iranian authorities, and any indications of broader involvement by regional or international actors. For India and other emerging markets heavily reliant on Gulf crude imports, the developments warrant careful assessment of strategic petroleum reserves and diversification strategies to mitigate exposure.
