After the Saudi pipeline attack, Gulf exports expanded: seven super tankers loaded 14 million barrels; Brent briefly breached $100 per barrel while WTI fell over 6%.

Saudi Aramco restructured its crude export routes at a pace exceeding market expectations, rapidly eroding the supply disruption premium that had built up following the pipeline attack. This placed downward pressure on international crude futures, which accelerated their decline on Monday, with Brent briefly falling below the $100-per-barrel threshold. According to data from TankerTrackers.com, Saudi Aramco loaded approximately 14 million barrels of crude oil onto seven Very Large Crude Carriers (VLCCs) in the Gulf region on Sunday. Media reports noted satellite imagery showing these tankers anchored near the Ras Tanura port. This unusually large loading volume signaled a strong rebound in Saudi exports, directly dampening bullish sentiment in the oil market and prompting traders to price in Saudi Arabia’s swift export recovery. On Monday, September 21 (U.S. Eastern Time), Brent crude futures closed down $3.53, or 3.4%, at $100.34 per barrel—having dipped below $100 intraday for the first time since September 9. U.S. WTI crude for October delivery fell 4.51% to $95.78 per barrel, hitting an intraday low of $94.22—the steepest intraday drop of over 6%. Both contracts posted their lowest closes since September 8, with Brent and WTI each registering four consecutive days of losses—the longest such streak since June 16 and June 24, respectively—and cumulative declines of 7.73% and 9.5% over those four days. Meanwhile, rising market expectations of U.S.–Iran diplomatic progress further depressed geopolitical risk premiums. Trump indicated willingness to meet Iranian President Masoud Pezeshkian, who is scheduled to attend the United Nations General Assembly this week. Tamas Varga, analyst at PVM Oil Associates, noted investors are pinning hopes on a potential breakthrough in negotiations this week. Exceeding expectations in loading volume and rapid export route restructuring On September 13, a drone attack forced Saudi Arabia to shut down its East–West pipeline, halting all crude loading operations at the Yanbu port on the Red Sea coast. Yet within less than a week, Saudi Aramco completed a large-scale shift in export routes—a speed faster than some market participants had anticipated. According to Reuters’ citation of Vortexa data, Saudi crude loading volumes via the Gulf averaged about 3.7 million barrels per day since September 12—up from roughly 2.9 million bpd earlier in the month. Between September 1 and 11, Saudi loading volumes via the Red Sea averaged about 3.9 million bpd. In a report issued last Friday, JPMorgan analysts pointed out that satellite data showed Saudi daily crude flow through the Strait of Hormuz had risen to 2.9 million bpd over the past six days—up sharply from just 700,000 bpd in August. The Sunday loading of ~14 million barrels further confirmed Saudi Arabia’s capacity to swiftly pivot export focus toward Gulf ports—and suggested the duration of this supply disruption may be shorter than the market’s most pessimistic prior forecasts. Oil price retreat: fading geopolitical premium meets diplomatic expectations

De facto U.S.–Iran negotiations? Iranian concessions? Persistent disagreements? Saudi export restoration? Overnight oil prices oscillated amid competing bullish and bearish signals.

International oil prices experienced sharp intraday volatility on Monday, swinging wildly as conflicting bullish and bearish news hit markets in rapid succession—resulting in a true 'roller-coaster' session that ultimately narrowed gains and even turned negative at times. The resumption of Saudi Arabia’s East–West pipeline, positive signals from U.S.–Iran nuclear talks, reports that Iran agreed to suspend uranium enrichment, and immediate U.S. negotiator statements highlighting persistent disagreements—all emerged within hours, turning the crude futures market into a veritable 'headline roulette'. That day, WTI crude peaked at $96.54 per barrel, gaining nearly 4.5% intraday; Brent rose as high as $108.83 per barrel, up over 4.3%. Yet as U.S.–Iran diplomatic developments flooded in, both contracts quickly pared gains: WTI slid to $91.25—down nearly 1% intraday—while Brent dropped to $103.76, shedding over $5 from its intraday high. The core market logic centered not on whether diplomacy had already delivered tangible supply restoration, but rather on whether diplomatic progress could *materialize* into actual supply increases. Meanwhile, media reports cited informed sources indicating that Iranian officials privately expressed pessimism about reaching a deal before the U.S. midterm elections on November 5, believing the likelihood of escalating conflict *after* the election is relatively high. This stance stood in stark contrast to the brief wave of optimism seen during the session—and contributed to the inability of oil prices to sustain any one-directional move. Dense barrage of U.S.–Iran diplomatic news drives algorithm-driven intraday volatility What truly triggered the 'roller-coaster' price action was the concentrated wave of U.S.–Iran diplomatic news hitting markets during the afternoon trading session. As compiled by ZeroHedge, the sequence of headlines unfolded chronologically: CNN reported Trump was willing to ease sanctions in exchange for nuclear progress—prompting an immediate price drop; shortly after, Saudi outlet Alhadath reported Iran had agreed to suspend uranium enrichment—further pushing prices lower; then came word that Iranian officials were pessimistic about pre-election agreement—triggering a rebound; finally, a U.S. negotiator told Al Arabiya TV that 'differences are huge and obstacles significant'—reigniting selling pressure. Bloomberg analyst Frank Monkam observed a resurgence of so-called 'VaR shock' strategies over recent trading days—where headlines are deliberately timed around midday U.S. Eastern Time, when liquidity tends to thin. The logic: Brent’s $105–$110 range (and WTI’s ~$95 level) represents key psychological thresholds; verbal pressure can depress prices *and*, by amplifying volatility, force traders to significantly reduce positions. From peak to trough that day, WTI plunged from $96.54 to $91.25, and Brent fell from $108.83 to $103.76—both shedding more than $5 within hours. Saudi pipeline restart—the first concrete supply-side relief The first substantive bearish catalyst for oil prices that day came from the restoration of Saudi Arabia’s East–West pipeline. As reported by Wall Street Insights, citing The Wall Street Journal and informed sources, Saudi Aramco began loading crude at the Red Sea port of Yanbu via the East–West pipeline as of Sunday, with current throughput running at approximately 3.5 million barrels per day.
