Brussels, Belgium, 29 October, (Brussels Morning Newspaper) – Oil prices decline in international trading on Thursday as renewed hopes of diplomatic negotiations between the United States and Iran ease concerns about disruptions to global energy supplies. However, continuing tensions across the Middle East and threats to critical energy infrastructure have prevented a more substantial fall in crude prices.
Brent crude futures fell by $1.22, or 1.1%, to $114.10 per barrel at 03:51 GMT, while US West Texas Intermediate (WTI) crude dropped by $1.33, or 1.3%, to $101.45 per barrel, according to Reuters.
The decline followed Wednesday’s gains, when Brent increased by 1.3% and WTI advanced by 3%, highlighting the sensitivity of energy markets to geopolitical developments.
Oil Prices Decline as US-Iran Diplomacy Gains Attention
Renewed diplomatic efforts involving Washington and Tehran have encouraged investors to reassess the risk of prolonged supply disruptions.
The Wall Street Journal reported that US Vice-President JD Vance had sought to restart negotiations through a letter addressed to Iranian security official Mohsen Rezaei.
Meanwhile, Qatari mediators presented Iranian officials with a draft proposal aimed at ending the conflict involving Iran, the United States and Israel.
Although a senior Iranian official reportedly rejected the proposal as unacceptable, Tehran’s foreign minister indicated that diplomatic engagement remained possible.
These developments have raised expectations that further negotiations could reduce regional tensions.
Middle East Conflict Continues to Threaten Oil Supplies
Despite growing diplomatic hopes, the regional security situation remains uncertain.
Reports of intensified Houthi attacks targeting Saudi Arabia have renewed concerns about the safety of energy facilities and important shipping routes.
Market participants remain particularly concerned about potential disruptions affecting the Strait of Hormuz, a strategically important passage for international oil shipments.
Yuki Takashima, an economist at Nomura Securities, told Reuters:
“Selling pressure is prevailing amid expectations that peace talks may resume.”
He added:
“However, the decline remains limited.”
His assessment reflects the competing influences of diplomatic optimism and continuing military risks.
Global Energy Markets Face Supply and Demand Pressures
The International Energy Agency’s October 2026 Oil Market Report forecast that global oil demand would decline by approximately 2.6 million barrels per day during 2026.
The agency linked weakening demand partly to restricted fuel availability, higher energy costs and deteriorating economic conditions associated with the Iran conflict.
Meanwhile, US government inventory figures showed crude stocks falling by 1.9 million barrels during the week ending 23 October.
Petrol inventories increased by 3.9 million barrels, presenting a mixed picture of American energy market conditions.
Expectations of recovering Russian refinery operations and additional crude production have also influenced international prices.
Falling Oil Prices Could Ease Pressure on European Economies
For the European Union, lower crude prices could eventually provide relief to businesses and consumers facing elevated energy costs.
Transport operators, manufacturers, airlines and logistics companies are particularly exposed to fluctuations in petroleum prices.
Belgium and other European economies could benefit from reduced import costs if international prices continue falling.
However, lower crude benchmarks do not guarantee immediate reductions in retail petrol or diesel prices.
Refining costs, taxation, distribution expenses and exchange rates also influence what consumers ultimately pay.
What Happens Next for Oil Markets?
Investors will closely monitor developments in US-Iran diplomacy, regional military activity and forthcoming energy supply figures.
No comprehensive peace agreement has been confirmed, and significant differences remain between the negotiating parties.
The direction of crude prices will therefore depend on whether diplomatic discussions produce measurable progress and whether Middle Eastern energy infrastructure remains secure.
For European policymakers, continued volatility reinforces the importance of energy security, diversified supplies and resilience against international market disruptions.
