Brent crude oil prices climbed above $110 per barrel on Wednesday, October 21, approaching five-month highs as escalating tensions in the Middle East, attacks on shipping routes and uncertainty surrounding U.S.-Iran diplomatic efforts raised concerns about global energy supplies.
Brent futures rose $2.06, or 1.9%, to $110.85 per barrel by 10:48 GMT, while U.S. West Texas Intermediate (WTI) crude gained $2.13, or 2.2%, to $99.95, according to Reuters. The increase followed a volatile trading session on Tuesday, when Brent reached $111.99 before retreating amid reports of possible diplomatic mediation involving Iran and Pakistan.
The latest gains extend a broader rally that has brought Brent above its September highs and renewed concerns about the impact of elevated energy prices on inflation, transportation costs and economic growth.
Market analysts are closely watching whether Brent can maintain its upward momentum, with technical indicators pointing to the possibility of further increases despite signs that prices may be approaching overbought levels.
Iran Conflict and Shipping Disruptions Push Prices Higher
Geopolitical developments remain a major factor driving oil prices, particularly the continuing conflict involving Iran and the United States and renewed threats to shipping in the Strait of Hormuz, one of the world’s most important routes for oil transportation.
Concerns intensified following reports of attacks on commercial vessels near the strait and in the Gulf of Oman. Iran’s Revolutionary Guards said Tuesday that a supertanker had caught fire after striking a sea mine south of the Strait of Hormuz, while shipping data indicated at least 18 attacks on vessels over a two-week period.
Iran-aligned Houthi forces in Yemen have also claimed attacks against Saudi energy and transportation infrastructure, including facilities near Yanbu, raising additional concerns about oil exports through alternative shipping routes.
Diplomatic uncertainty has further supported prices. Iranian Foreign Minister Abbas Araqchi said Tehran was prepared to defend itself, while President Masoud Pezeshkian indicated that negotiations with Washington could not proceed under continued military and economic pressure.
The statements followed discussions in Tehran involving Pakistan’s military leadership, which had briefly raised expectations of renewed mediation efforts and contributed to a temporary decline in oil prices.
The conflict between Russia and Ukraine has added another source of uncertainty. Ukrainian drone attacks targeting Russian oil facilities have raised concerns about possible disruptions to Russian crude and refined-product supplies. Meanwhile, Washington’s decisions concerning sanctions on Russian energy exports have introduced further uncertainty over how much oil could reach international markets.
Despite these risks, Middle Eastern producers have managed to restore significant export volumes by using alternative transportation routes. According to data reported by the Financial Times, Gulf oil exports excluding Iran reached an average of 24.6 million barrels per day in the week ending October 18, exceeding levels recorded before the outbreak of the conflict earlier this year.
Brent Could Approach $117 as Markets Assess Supply and Demand
Brent’s recent advance has brought several important price levels into focus, with analysts examining whether the international benchmark can sustain its gains.
In a weekly technical outlook published on October 18, market analyst Razan Hilal identified $108 per barrel as a significant resistance level corresponding to Brent’s September highs. A sustained move above that threshold could bring the next resistance area near $117 into focus.
With Brent already trading above $110 on Wednesday, attention has shifted toward whether the latest increase can continue or whether profit-taking and easing geopolitical tensions could trigger a correction.
On the downside, the analysis identifies $104 and $100 as important support levels, with a more substantial decline potentially bringing prices toward $94.
The outlook for WTI is similarly sensitive to developments in the Middle East. A sustained move above $100, followed by $105, could open the way for another test of this year’s higher price levels.
Supply data have also contributed to upward pressure. U.S. commercial crude inventories fell by 8.6 million barrels in the week ending October 9, leaving stocks approximately 3% below their five-year average. Preliminary industry figures subsequently indicated another decline of 4.9 million barrels in the week ending October 16.
At the same time, the International Energy Agency has lowered its forecast for oil demand growth in 2026, citing high energy prices, supply restrictions and deteriorating economic conditions. Emergency stock releases have also been used to ease pressure on the market.
Political developments could contribute to further volatility, particularly ahead of Israel’s national elections on October 27 and the U.S. midterm elections on November 3. Rising fuel prices have become a concern for the Trump administration as Republicans prepare for the congressional vote.
For oil-importing economies, including Greece and other European countries, sustained Brent prices above $100 could increase pressure on fuel costs, transportation expenses and consumer prices, depending on exchange rates, refining margins and domestic taxation.
The immediate direction of Brent will depend heavily on developments in U.S.-Iran diplomacy, maritime security in the Persian Gulf and the extent to which major producers can maintain exports despite continuing regional instability.
