Crude oil prices moved sharply higher on Wednesday, with Brent crude briefly crossing the $100-a-barrel mark for the first time since July as the escalating US-Iran conflict raised fresh concerns about global oil supplies.
Brent crude futures climbed to around $100.19 a barrel before easing slightly, while US West Texas Intermediate (WTI) rose above $94 a barrel. The latest jump came as renewed attacks in the Middle East increased fears that the conflict could disrupt oil production, shipping and supplies from the region.
The oil market has been particularly sensitive to developments around the Strait of Hormuz, one of the world’s most important energy routes. The waterway has faced severe disruption since the conflict began, forcing traders and shipping companies to reassess the risks involved in moving crude through the region.
The situation worsened after Iran said it had attacked a US military base in Jordan following American strikes on Iranian vessels. Tehran also warned oil tankers operating near Kuwait and Bahrain and urged crews to leave their ships, adding another layer of uncertainty for the global energy market.
At the same time, Iran-backed Houthi forces in Yemen have intensified attacks on Saudi energy infrastructure. The attacks included the Jazan refinery, raising concerns about another important source of Middle Eastern oil supply and increasing pressure on alternative shipping routes through the Red Sea and the Bab al-Mandab chokepoint.
The developments have pushed traders to price in a larger geopolitical risk premium for crude. While oil prices had already been climbing because of the prolonged conflict, the latest attacks have increased concerns that the disruption could last longer than previously expected.
Data cited by Reuters showed that oil flows through the Strait of Hormuz had recently fallen below 2 million barrels per day, compared with roughly 8 million to 9 million barrels per day during a brief period before fighting resumed. The Strait is a crucial route for Middle Eastern energy exports, making any prolonged disruption a serious concern for oil-importing economies.
The rise in crude prices is also creating problems beyond the energy market. Higher oil prices can increase transportation, manufacturing and logistics costs, eventually feeding into consumer prices. That is raising concerns about inflation at a time when several major central banks are considering their next interest-rate moves.
Investors are now closely watching US inflation data due later this week. A sustained increase in energy prices could make it harder for the US Federal Reserve to ease monetary policy if inflation begins to accelerate again. Higher borrowing costs, in turn, could weigh on businesses, consumers and financial markets.
European markets have already felt some of the pressure, with shares coming under strain as investors assessed the potential impact of higher energy costs. The prospect of stronger inflation and higher interest rates has made investors more cautious, particularly in sectors that are sensitive to borrowing costs.
Airlines, transport companies, manufacturers and other fuel-intensive industries are likely to face higher operating costs if crude remains elevated. Consumers could also feel the impact through higher petrol, diesel and other energy-related expenses.
Oil-importing economies such as India are particularly vulnerable to a prolonged period of high crude prices. Higher import bills can put pressure on the country’s trade balance and inflation, while also increasing demand for dollars. That can put additional pressure on the Indian rupee.
The rise in crude has already been reflected in currency markets. The Indian rupee fell to ₹94.81 against the US dollar on Tuesday, its steepest decline in more than a month, with higher oil prices adding to concerns about the country’s import bill.
The wider concern is that the current oil shock may not be temporary. Analysts have warned that continued attacks on tankers or energy infrastructure could push prices significantly higher. Goldman Sachs has indicated that crude could move towards $120 a barrel if shipping disruptions intensify and exports remain constrained.
At the same time, additional production from countries such as the United States, Canada and Guyana could provide some relief to the global market. However, the International Energy Agency expects global oil supply to decline by about 4.3 million barrels per day in 2026, highlighting the difficulty of quickly replacing disrupted Middle Eastern supplies.
The oil market is therefore facing two competing forces: additional production outside the region on one side and rising geopolitical risks on the other.
Traders remain focused on developments in the Strait of Hormuz, Saudi energy infrastructure and the wider US-Iran conflict. Any sign of de-escalation could quickly ease crude prices, but further attacks on oil facilities or shipping could send them higher.
With Brent now testing the psychologically important $100 level, the next few days could be crucial for energy markets. A prolonged period above that threshold would not only increase fuel costs but could also complicate the global fight against inflation and influence decisions on interest rates, currencies and economic growth.
The immediate question for markets is no longer simply whether crude can touch $100. It is whether the geopolitical crisis will keep it there.
