The oil price enters the week of September 14–18 with a new problem that could overwhelm almost every normal market catalyst. Saudi Arabia’s East-West pipeline — the crucial route used to move crude toward the Red Sea while avoiding the disrupted Strait of Hormuz — remains offline after drone attacks, potentially putting around 4 million barrels per day of exports at risk if the outage persists. That is roughly 4% of global oil supply, and Saudi inventories at the Red Sea port of Yanbu may provide only five to seven days of breathing room.
That countdown could make the coming trading week exceptionally volatile. Brent crude finished Friday at $104.61 a barrel after touching $107.63 the previous day, while West Texas Intermediate had also broken above $100 before retreating. Oil still gained more than 8% over the week as tanker attacks, shrinking Middle Eastern supply and fears surrounding the Strait of Hormuz forced traders to rebuild the geopolitical risk premium.
The critical question now is no longer whether oil can trade above $100. It already has.
The question is whether a prolonged Saudi pipeline outage turns $100 into a floor rather than a ceiling.
Monday’s Oil Price Open Could Be the First Major Test
The first signal arrives when crude markets reopen.

Friday’s decline in Brent from Thursday’s highs showed that traders were still willing to take profits after a sharp rally. Brent settled at $104.61 on September 11, down 2.8% on the day, while WTI slipped back after briefly moving above $100. But those prices were established before markets had an entire weekend to evaluate the growing threat to Saudi Arabia’s bypass infrastructure.
Since then, the situation has not clearly improved.
The East-West pipeline remains offline, according to Reuters reporting on Sunday. Attacks around the Strait of Hormuz have continued, Houthi advances have increased concerns surrounding the Red Sea and Bab el-Mandeb, and a planned Oman meeting involving Gulf states and Iran over navigation through Hormuz has been postponed without a new date.
That combination creates obvious upside risk when Asian trading begins.
A sharp Monday gap higher would indicate traders believe the shutdown is likely to last long enough to threaten physical exports. A muted response, by contrast, would suggest the market expects Saudi Arabia to restore the pipeline before Yanbu inventories become critically low.
That makes Monday less about a specific dollar target and more about one question: does the market begin pricing the loss of Saudi barrels that have so far continued reaching customers?
The Five-to-Seven-Day Countdown Is What Makes This Week Different
Saudi Arabia’s East-West pipeline normally allows crude produced in the kingdom’s east to move roughly 1,200 kilometers across the country toward Yanbu on the Red Sea.
That route has become dramatically more important because normal Gulf exports remain severely disrupted by the conflict around Iran and the Strait of Hormuz.
Reuters reports that around 4 million barrels per day had been moving through the pipeline. If the line stays closed, crude already stored at Yanbu could maintain exports for approximately five to seven days, after which available inventories could begin running short. Some additional barrels are stored at Egyptian facilities, but the backup capacity is limited.
That timetable overlaps almost perfectly with the upcoming trading week.
In other words, by Friday, September 18, the oil market could have much better visibility on whether this was a temporary infrastructure interruption or the beginning of a meaningful new loss of physical supply.
And the market is already starting from an unusually tight position.
The International Energy Agency said Friday that global oil supply is now expected to average just 100.7 million barrels per day in 2026, down 5.7 million barrels per day from last year. The agency cut its supply estimate by another 1.3 million barrels per day compared with its previous forecast and no longer expects a full recovery in Middle Eastern production until 2027.
That leaves remarkably little room for another multi-million-barrel disruption.
A Pipeline Restart Could Send Brent Back Below $100 Fast
The bullish oil case is powerful, but traders should not confuse geopolitical risk with a guaranteed one-way move.
The single most important bearish catalyst this week would be confirmation that Saudi Arabia has repaired or safely restarted the East-West pipeline.
If normal flows resume before Yanbu inventories become depleted, a substantial portion of the weekend risk premium could disappear almost immediately. Crude has already shown how violently it reacts to changing perceptions of Middle East supply. Brent surged 6.3% on September 10 alone, then fell nearly 3% the following session.
That volatility works both ways.
A credible restart combined with progress toward renewed Gulf-Iran maritime negotiations could push Brent back toward — or potentially below — the $100 threshold. Markets do not need the entire Middle East conflict to end for oil to fall. They merely need the probability of losing another 4 million barrels per day to decline materially.
That is the key distinction for the coming week.
The current price includes fear of what might disappear from the market. If Saudi exports keep flowing, part of that fear premium can be removed just as quickly as it arrived.
But a Prolonged Shutdown Could Put $110 Oil Back in Play
The upside scenario becomes much more dangerous if there is still no pipeline restart by the middle of the week.
Thursday’s $107.63 Brent settlement has already demonstrated that traders are prepared to push crude toward $110 when tanker attacks escalate. A confirmed deterioration in Saudi export capacity would give the market a much more concrete supply problem to price.
A move back through the recent $107–$108 zone would therefore be the first major technical and psychological test. If the market breaks convincingly above those levels while Saudi exports remain threatened, $110 would become an obvious next battleground.
Beyond that, exact forecasts become increasingly speculative because oil would be trading on military events rather than conventional inventory mathematics.
The important issue is scale.
Losing even a substantial fraction of the 4 million barrels per day currently at risk would come on top of an already enormous reduction in Gulf supply. Reuters reported this week that roughly one-third of Gulf oil exports remain missing compared with pre-war levels despite some tankers making so-called “dark crossings” through Hormuz with tracking systems switched off.
That is why the next disruption could have a disproportionately large price impact.
The easy replacement barrels have already been used.
Diesel May Be an Even Bigger Warning Signal Than Brent
Investors focused only on crude could miss the market’s most alarming development.
U.S. diesel prices have already exceeded $6 per gallon for the first time, reflecting not only Middle Eastern crude disruptions but also severe pressure on global refining and product exports.
The IEA estimates that Gulf diesel and gasoil exports averaged only about 390,000 barrels per day in August — barely more than one-quarter of their pre-war level. Russian refining disruptions have further tightened the market, leaving combined Gulf and Russian diesel exports roughly 1.6 million barrels per day below February levels.
That matters because crude oil does not hit the economy directly. Diesel, gasoline and jet fuel do.
If crude stays above $100 while diesel remains at record levels, the consequences extend rapidly into trucking, airlines, agriculture, manufacturing and consumer inflation.
And that leads directly to another major market event this week.
The Federal Reserve Could Turn the Oil Shock Into a Broader Market Story
The Federal Reserve meets on September 15–16, with its decision due Wednesday.
Markets are already pricing a high probability of a quarter-point interest-rate increase after stronger-than-expected inflation data. Reuters reported that expectations of a September hike jumped following an August core CPI increase of 0.3%, while headline inflation reached 3.4%.
The Federal Reserve’s own calendar confirms that the two-day meeting concludes September 16, followed by the policy statement and press conference.
Oil therefore arrives at a particularly dangerous moment.
If Brent moves toward $110 early in the week, the Fed will be announcing policy into an economy facing another visible inflation shock. Rising energy prices could reinforce the case for keeping monetary policy tight and make future rate cuts even harder to justify.
That would broaden the impact from commodities into bonds, technology stocks, currencies and consumer-sensitive sectors.
Oil might start the fire. Interest rates could spread it.
Oil Price Forecast: Three Scenarios for September 14–18
The most useful way to approach the week is through scenarios rather than pretending anyone can reliably predict the next military headline.
The bearish oil scenario requires a rapid Saudi pipeline restart, no major new tanker attacks and renewed progress on negotiations over Hormuz. Under those conditions, Brent could surrender a meaningful portion of its geopolitical premium and retest the area around $100.
The base case is continued uncertainty: the pipeline remains impaired for part of the week but Saudi inventories keep exports flowing while officials work on repairs. That would likely leave Brent volatile in the low-to-upper $100s, with every infrastructure and diplomatic headline capable of moving prices several dollars.
The bullish oil scenario is the dangerous one. If Saudi authorities fail to restore the pipeline before Yanbu inventories begin running low — particularly alongside further attacks around Hormuz or Bab el-Mandeb — traders may have to price an actual loss of Saudi exports rather than merely the risk of one. In that environment, a renewed break above $107–$108 could quickly put $110 and potentially higher levels back in focus.
The exact number matters less than the catalyst.
This Week Could Decide Whether $100 Oil Is Temporary or the New Normal
The upcoming week is unusual because the most important oil catalyst has an actual clock attached to it.
Saudi Arabia may have only five to seven days of readily available Yanbu inventories capable of maintaining exports while its East-West pipeline is offline. That gives traders a narrow window in which they should learn whether the infrastructure can be restored before physical supply starts disappearing.
Monday will reveal how much additional fear the market prices after the weekend. Wednesday brings the Federal Reserve decision. By Thursday and Friday, attention could shift almost completely toward Saudi export flows and the pipeline’s status.
The most important levels are straightforward: roughly $100 as the psychological support zone, the recent $107.63 Brent high as the immediate upside reference, and $110 as the next major test if the disruption worsens.
But the real signal will not be on the chart.
It will come from Yanbu.
If Saudi Arabia restores the pipeline quickly, oil could reverse sharply as one of the market’s biggest immediate fears disappears. If the week ends with the pipeline still offline and inventories running down, the market will enter the following weekend facing the possibility that millions of barrels of daily supply are no longer merely threatened — they are actually missing.
At that point, the oil price story could become much bigger than $100.
