Global crude oil prices have surged sharply over the past week, reaching their highest levels in more than a year as escalating geopolitical tensions in the Middle East raise fears of major disruptions to global energy supplies.
Brent crude oil, the international benchmark, has climbed to $84 per barrel, marking its highest level since mid-2024 and extending a rapid rally that has unfolded over several trading sessions.
Strait of Hormuz concerns drive rally
The surge has been driven primarily by concerns about the security of the Strait of Hormuz, a narrow shipping route between Iran and the Gulf states through which roughly 20 percent of the world’s oil supply passes. Reports of attacks on vessels, threats to close the waterway and broader regional conflict have prompted shipping disruptions and increased insurance costs for tankers, raising the risk of supply constraints in global energy markets.
Rapid price gains reflect risk premium
Oil prices have reacted quickly to the geopolitical risk premium. In some trading sessions this week Brent crude rose 7 – 9 percent in a single day, while US benchmark West Texas Intermediate (WTI) also posted sharp gains as traders priced in the possibility that exports from the Middle East could be curtailed.
The rally builds on an already volatile market: crude prices had been climbing earlier in the year amid tensions between the United States and Iran and concerns about supply outages. Since early January a 36% oil price rise has so far been seen.
Shipping disruptions tighten supply chains
Another factor supporting prices is uncertainty around shipping and logistics. Tanker traffic through the Gulf has slowed as operators reassess safety risks, with several companies temporarily halting transit through Hormuz. Even without a formal closure of the strait, these disruptions can tighten global supply chains and amplify price movements because the route is critical for oil shipments from Saudi Arabia, Iraq, the UAE and other producers.
Prices remain below extreme levels
Despite the sharp rally, analysts note that oil has not yet approached the extreme levels seen during earlier geopolitical crises. Brent crude remains below the $100 per barrel threshold that markets often view as a key psychological level, partly because global supply has diversified in recent years with growing production from the United States, Brazil and Guyana.
Forward outlook depends on escalation
Looking ahead, the direction of oil prices will largely depend on whether tensions in the region escalate or stabilise. If shipping through the Strait of Hormuz is further disrupted or major oil infrastructure is affected, prices could climb significantly higher. Conversely, diplomatic progress or additional supply from OPEC+ producers could ease market fears and limit further gains.
Markets will monitor developments closely adjusting positions as new information emerges.
Worst-case scenarios involve sustained Hormuz closure or attacks on major production facilities. Such events could drive oil towards or above $100 per barrel.
Base-case assumptions incorporate continued reduced but functioning Hormuz traffic. This scenario supports current elevated price levels.
Inflationary implications of oil surge
For now, the rapid rise in crude prices is reverberating across global financial markets and raising concerns about renewed inflationary pressure, as higher energy costs filter through to fuel prices, transportation and broader consumer goods.
Inflation sensitivity to energy costs varies by economy. Countries importing substantial oil face greater exposure than producers.
Central banks monitor oil-driven inflation carefully. Sustained energy price increases complicate monetary policy decisions whereby interest rate expectations may shift if oil prices remain elevated.
Whereas persistent inflation reduces scope for rate cuts, so does a potential spike in inflation, driven by higher input costs such as oil. In the UK, for example, analysts no longer expect the Bank of England (BoE) to cut rates in March.
Impact on different sectors
Oil price surges create winners and losers across economic sectors. Energy companies benefit from higher revenues and improved profitability.
Integrated oil majors including Shell, BP and ExxonMobil see upstream earnings increase. Refining margins also typically improve during supply disruptions.
Airlines and transportation companies face margin pressure from higher fuel costs, though, and are particularly exposed to oil price movements.
Chemical manufacturers using petroleum feedstocks experience input cost increases and margins compress unless pricing power allows pass-through.
Historical context for current levels
Oil prices have experienced substantial volatility over recent years providing context for current levels. The pandemic saw unprecedented collapse to negative prices.
Recovery through 2021 – 2022 drove oil above $120 per barrel as the Russian invasion of Ukraine created supply concerns.
The subsequent decline through 2023 and 2024 reflected recession fears and demand concerns with prices stabilising in the $70 – 90 range.
