Oil prices fell sharply on Monday, retreating from their highest levels since March as diplomatic efforts involving Iran appeared to gain momentum. The move offered some relief to European markets, although continued attacks in the Gulf meant that supply risks remained significant.
Brent crude, the global benchmark, dropped by more than 6% from Friday’s close of approximately $117.40 per barrel to around $110 at the time of reporting. US West Texas Intermediate fell by about 2% to roughly $101.50 per barrel.
Why oil prices are falling
The decline followed reports that regional mediators were travelling to Tehran and that US President Donald Trump was considering a possible agreement with Iran. Qatar’s mediators reportedly visited the Iranian capital, while senior officials from Saudi Arabia, Pakistan and Türkiye were expected to take part in security discussions.
The diplomatic activity has encouraged investors to reduce some of the risk premium built into oil prices during the conflict. Oil had risen rapidly after attacks linked to Yemen’s Houthi movement targeted airports and energy infrastructure in Saudi Arabia.
However, the fall in prices does not mean the energy situation has stabilised. The Houthis said they had carried out further attacks over the weekend, while Saudi authorities reported intercepting additional missiles and drones.
Brent remains well above pre-conflict levels
Despite Monday’s decline, Brent crude remained substantially higher than before the conflict. It had traded at about $72 per barrel before the war and reached approximately $119.50 in early March.
Friday’s closing price was the highest for Brent since 19 March and only around 2% below the recent peak. The latest movement therefore represents a retreat from unusually elevated prices rather than a return to normal market conditions.
The importance of the Strait of Hormuz
Investors continue to monitor the Strait of Hormuz, a strategically important route for global energy shipments. Before the conflict, roughly one-fifth of the world’s oil passed through the waterway.
US President Donald Trump said oil flows through the strait had exceeded pre-war levels. Separate data from ship-tracking company Kpler indicated that Gulf crude exports excluding Iran had returned to pre-conflict levels in September, although a larger share was being transported through pipelines.
According to the figures cited in the report, about 40% of those exports were bypassing the strait through pipelines, compared with 17% before the conflict. That shift could reduce exposure to disruption, but it does not eliminate the wider security risks affecting producers, shipping routes and energy markets.
European markets respond cautiously
European shares moved higher as investors welcomed the possibility that diplomatic talks could reduce pressure on energy supplies. The pan-European Stoxx 600 and Euro Stoxx 50 were both more than 0.6% above Friday’s close.
Major national indices also advanced:
- Germany’s DAX led the gains among the main markets.
- France’s CAC 40, Italy’s FTSE MIB, Switzerland’s SMI and the UK’s FTSE 100 rose between 0.3% and 1%.
- Spain’s IBEX 35 and the Netherlands’ AEX were broadly unchanged.
French assets received additional support after Moody’s maintained France’s Aa3 credit rating, contrary to some expectations of a downgrade.
For European consumers and businesses, the oil market remains important because sustained energy prices can influence transport costs, inflation, household bills and industrial production. A lasting fall in crude prices could ease some pressure, but the effect on retail fuel and wider consumer prices would depend on currency movements, taxes, refining costs and how long the decline continues.
Central banks and corporate results dominate the week
Oil market developments are unfolding during a particularly busy period for investors. Several major central banks are due to announce interest-rate decisions, while large companies are reporting quarterly earnings.
The US Federal Reserve is scheduled to announce its decision on Wednesday. The European Central Bank is due to follow on Thursday, with attention focused partly on financial-market conditions in France. The Bank of Japan is expected to announce its decision on Friday.
Markets were widely expecting the Federal Reserve to keep its policy rate within the 3.75% to 4% range, while investors were also assessing the possibility of a later increase. These expectations can affect currency markets, borrowing costs and the price of commodities such as oil.
Corporate reporting is also intensifying. Around one in three S&P 500 companies was expected to report during the week, including Alphabet, Microsoft and Amazon. In Europe, BP and Shell were among the energy companies due to update investors.
What happens next?
The immediate direction of oil prices will depend on whether diplomatic contacts produce a credible reduction in hostilities and whether energy infrastructure and shipping routes remain secure.
Markets will be watching several developments closely:
- Whether talks involving Iran lead to a confirmed agreement or remain exploratory.
- Whether attacks on Saudi infrastructure and regional transport routes continue.
- Whether oil shipments through the Strait of Hormuz remain stable.
- How the European Central Bank and other central banks respond to inflation and growth risks.
- Whether company earnings provide further evidence of the effect of high energy costs.
For Europe, the main takeaway is that the fall in crude prices reflects improved expectations about diplomacy, not the disappearance of geopolitical risk. Until security conditions become more durable, energy markets are likely to remain sensitive to official statements, attacks and developments around the Strait of Hormuz.
