Oil prices surged on Monday, 9 March 2026, as market participants reacted to a sharp slowdown in shipments through the Strait of Hormuz following a week of hostilities involving the United States, Israel and Iran. The move refocused attention on energy security and supply continuity across Asia, Europe and North America. According to market data cited in broadcast reports, the early session signalled a wider risk-off shift, with energy and transport-exposed equities under pressure and volatility indicators rising across futures curves.
By early Asian trade, Brent crude was almost 24% higher at $114.74 a barrel, while US Nymex light sweet crude rose by more than 26% to $114.78. Equity indices fell: Japan’s Nikkei 225 by more than 7%, Hong Kong’s Hang Seng by over 3%, and Australia’s ASX 200 by more than 4%. South Korea’s Kospi slipped by over 8%, triggering a 20‑minute trading halt; the same circuit-breaker mechanism also activated on Wednesday after a 12% intraday fall.
Over the weekend, the United States and Israel carried out further airstrikes across Iran, including reported hits on oil depots. In Tehran, authorities announced Mojtaba Khamenei as successor to his father, Supreme Leader Ali Khamenei, indicating leadership continuity a week into the conflict, according to BBC reporting. The combination of military escalation and perceived leadership consolidation contributed to a swift repricing of supply risk.
Roughly one‑fifth of global crude exports typically transits the Strait of Hormuz. Market sources indicate that traffic through the narrow channel has largely paused since the fighting began, concentrating risk in a single maritime chokepoint for both crude oil and liquefied natural gas. The immediate operational question is whether partial transits can resume safely under current security conditions and insurance terms.
Two structural constraints now shape the policy response. First, physical rerouting options are limited. While some Gulf producers can divert volumes via pipelines to the Red Sea or the Gulf of Oman, available capacity cannot fully offset a multi‑week blockage of Hormuz. Second, financial cover is tightening as war‑risk insurance is repriced and sanctions compliance checks extend chartering timelines, creating frictions even where routes remain technically open.
The price shock is already feeding into refined products. Jet fuel benchmarks typically move with a short lag to crude, while chemical and fertiliser precursors linked to naphtha and gas-based feedstocks trend higher when crude spikes. If current levels persist through March, airlines, shippers and agricultural suppliers should expect materially higher procurement costs.
Demand patterns are also shifting. The Gulf’s physical barrels are primarily consumed in Asia, and there are early signs of Asian buyers bidding up alternative supply. Some liquefied natural gas cargoes initially destined for Europe have reportedly turned in the mid‑Atlantic toward Asia, reflecting altered regional price signals and security calculations.
Governments retain several tools should disruption endure. Under the International Energy Agency’s emergency framework, member states can coordinate stockdraws and, if necessary, temporary demand restraint. In the United States, the Energy Policy and Conservation Act permits a Strategic Petroleum Reserve drawdown at the President’s direction in the event of a severe supply interruption, with parallel mechanisms across other IEA members through mandated commercial stocks and government‑held reserves.
Domestic affordability remains politically sensitive. President Donald Trump called the immediate price rise a “small price to pay” for addressing Iran’s nuclear programme, while the US Energy Secretary told domestic broadcasters that Israel-not the United States-was targeting Iran’s energy infrastructure. The comments came amid concern about rising pump prices and airline fuel surcharges.
Volatility has been acute. Traders reported that Brent rose about 10% within a minute of the open and added another 10% within 15 minutes during early Asian hours. Circuit breakers in Seoul and a broad sell‑off elsewhere highlight how quickly risk premia are rebuilding across energy and equity markets.
Some analysts warn that prices could climb further if the strait remains shut through the end of March, with estimates for potential records above $150 a barrel cited in market commentary. Adnan Mazarei of the Peterson Institute for International Economics said the surge was expected given halted production in parts of the Gulf and the likelihood that the conflict will not end quickly, adding that official assurances on insurance and transit are becoming less realistic.
In the near term, officials and markets will watch for signals of a controlled reopening at Hormuz, formal insurer notices on war‑risk cover, guidance from Gulf producers on diversion capacity, and any coordinated IEA action. For finance directors and procurement teams, the practical steps are to stress‑test cashflows, review hedge coverage, and budget for higher freight and input costs if disruption extends beyond March.
