A 14.25% fall so far this week has left US benchmark West Texas Intermediate (WTI) trading at $87.50 a barrel at the time of writing, following a test of support near $86.00 at the 200-day Simple Moving Average (SMA). Oil is recording its steepest weekly decline in months as the Democrats' landslide victory in the US midterm elections raises hopes that the war against Iran will end.

Wednesday's sharp sell-off in crude followed the resounding midterm election defeat of US President Donald Trump. The result confirmed disapproval of Republican policies, particularly the war in Iran and the effects of the resulting energy shock.
In an interview with the Financial Times on Wednesday, Trump maintained that he did not regret intervening in Iran, while stating that the US had no immediate plans to resume hostilities. Vice President JD Vance also identified the war in Iran as the principal reason for the election results on Wednesday, fuelling hopes that the government will seek a swift exit from the conflict.
Further losses in crude are being limited by persistent concerns over supply disruptions. Iran's Islamic Republican Guard Corps (IRGC) said on Thursday that two oil tankers had caught fire while attempting to pass through the Strait of Hormuz via what they called "an unauthorised route".

Momentum has weakened markedly as WTI US Oil trades at $87.52, only slightly above its 200-day simple moving average (SMA). On the daily chart, the Relative Strength Index (RSI) has fallen to 36.5. Meanwhile, the Moving Average Convergence Divergence (MACD) line has moved below the Signal line and the histogram has become more negative. Together, these indicators suggest the recent retreat is gathering pace, even though the broader trend remains positive.
A confirmed break below the $86.00 area would be viewed as a sign of a shift in trend, increasing downward pressure towards the late August lows around $79.30, followed by the 3 August low near $73.50. Any recovery would first encounter resistance at former support around $94.50, the 2 November low, before reaching last week's highs above $103.67.

Produced in the United States and distributed through the Cushing hub, WTI oil is a crude oil grade traded internationally. WTI stands for West Texas Intermediate and is one of three major grades, alongside Brent and Dubai Crude. Its relatively low gravity and sulphur content earn it the descriptions “light” and “sweet”, respectively. Regarded as a high-quality oil, it is easy to refine. Cushing is 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 determine WTI oil prices, as they do for other assets. Stronger global growth can lift demand, while weaker growth can have the reverse effect. Supply disruptions caused by political instability, war or sanctions can also affect prices. Another important influence is the production decisions made by OPEC, a group of major oil-producing countries. Since oil is traded mainly in US dollars, the value of the US dollar also shapes WTI crude prices: a weaker dollar can make oil more affordable, while a stronger dollar can do the opposite.
WTI oil prices respond to the weekly inventory reports from the American Petroleum Institute (API) and the Energy Information Agency (EIA), as changes in stockpiles reflect shifts in supply and demand. Falling inventories can signal stronger demand and push prices higher; rising inventories can indicate greater supply and weigh on prices. The API releases its report each Tuesday, followed by the EIA the next day. The two sets of figures generally agree, coming 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 that make up OPEC (Organization of the Petroleum Exporting Countries) jointly set production quotas for member countries. These decisions frequently affect WTI oil prices. Lower quotas can restrict supply and lift prices, whereas increased production has the reverse effect. The broader OPEC+ group brings in ten additional non-OPEC members, most notably Russia.
