December oil production targets were left unchanged by the Organization of Petroleum Exporting Countries and its allies (OPEC+) in an agreement reached on Sunday, weighing on crude prices. Following three days of gains, West Texas Intermediate (WTI) is trading lower at around $101.20 per barrel during Monday’s Asian session.

September’s required production levels will also apply in December, according to an official OPEC+ statement. The arrangement sets Saudi Arabia’s allocation at 10.478 million barrels per day (bpd), with Russia assigned 9.949 million bpd and Iraq 4.431 million bpd.
Diplomatic efforts to resolve the Middle East conflict added to the downward pressure on crude, although investors also considered the risk of renewed US military action against Iran. With the US midterm elections approaching, Qatari and Iranian officials held discussions for a third consecutive day in pursuit of an agreement to end the war.
Repeated warnings from Iran have made clear that fresh attacks would trigger retaliatory strikes on US and Israeli targets in neighbouring countries. Responding to those warnings, US President Donald Trump said no new US attacks on Iran would take place before the elections, citing progress in negotiations with Tehran. He nevertheless left open the possibility of further military action afterwards.
Mounting strains in the physical market, alongside geopolitical tensions, are playing an increasing role in Brent’s outlook, analysts at Rabobank warn. With energy infrastructure and key transit routes more exposed to disruption, they argue that “renewed escalation threatens physical supply directly,” while also stressing that “getting the barrels to market has become extraordinarily costly and fragile”. Although the so-called “Hormuz Shuttle” may be sustaining crude flows, record tanker rates, insurance and logistics costs mean “physical oil trades well above futures,” highlighting the premium attached to real-world barrels compared with paper markets.
Traded internationally, WTI oil takes its name from West Texas Intermediate and is one of three major crude types, alongside Brent and Dubai Crude. Its relatively low gravity and sulphur content earn it the descriptions “light” and “sweet”, respectively. This high-quality oil is regarded as easy to refine. Produced in the United States, it is distributed through the Cushing hub, known as “The Pipeline Crossroads of the World”. WTI serves as an oil market benchmark, with its price regularly cited by the media.
Supply and demand underpin WTI oil prices, as they do those of all assets. Stronger global growth can therefore lift demand, while weaker growth can have the reverse effect. Supply disruptions arising from political instability, wars or sanctions can also affect prices. Another important influence is the production policy of OPEC, a grouping of major oil-producing countries. Because crude is traded predominantly in US dollars, movements in the currency also affect WTI prices: a weaker US dollar can make oil more affordable, while a stronger dollar can do the opposite.
Weekly oil inventory figures from the American Petroleum Institute (API) and the Energy Information Agency (EIA) affect WTI prices by revealing shifts in supply and demand. Falling stocks can signal stronger demand and lift oil prices, whereas rising inventories can point to greater supply and weigh on prices. The API releases its report each Tuesday, followed by the EIA the next day. The two reports generally show similar results, with their figures within 1% of one another 75% of the time. As the EIA is a government agency, its data is regarded as more reliable.
At meetings held twice a year, the 12 oil-producing nations in OPEC (Organization of the Petroleum Exporting Countries) jointly set production quotas for member countries. These decisions frequently influence WTI oil prices: lower quotas can constrain supply and raise prices, while increased production has the reverse effect. The broader OPEC+ grouping brings in ten additional non-OPEC members, most notably Russia.
