WTI crudeoil traded at $80.73 per barrel on Monday, June 15, 2026, down almost 5% fromFriday's $84.88 close, after the United States and Iran reached an interim dealto reopen the Strait of Hormuz and drain the war premium from the oil market.Brent fell more than 4% to below $84, a fresh three-month low. The deal,set to be signed June 19 in Switzerland, would restart a waterway that oncecarried about a fifth of global oil supply. Traders now weigh a slow physicalrecovery against a 60-day window of US-Iran nuclear talks that could stillcollapse. In thisarticle I am showing why oil prices are falling down today, how low can oil go,and what are the newest oil price predictions from big banks.Followme on X for real-time market analysis: @ChmielDkOil Technical Analysis:WTI Price at the 200 EMAWTI crudehas fallen straight into its 200-day exponential moving average, a level itlast touched more than four months ago. My chart shows price gapping lower atthe Monday open and slicing below $81, almost 5% under Friday's settlement. That breakejects WTI from the choppy consolidation it has held since March, a rangewithout clean edges that traded between roughly $85 to $88 on the floor and$110 to $115 on the ceiling.Theboundaries are not random. The upper zone aligns with the 2022 highs I flagged when Brenttopped $115, whenWTI briefly ran toward $125 before stalling; this cycle's war spike topped outnear $120. The lower edge near $85 to $88 matches the April and July 2024peaks. With that floor broken, the old support now flips to resistance.The 200 EMAread carries weight because it sits near $80, almost to the pip on the January2025 highs, stacked on the round number and the June 2025 highs into one densesupport shelf. In 15-plusyears as a trader and analyst, 10 of them at FinanceMagnates.com, I have rarelyseen technical levels matter less than they do in this oil market. My priorcalls are archived on my analyst page, from the $112 April peak down to today's reversal. Price isbeing written by the US, Iran and Trump, not by moving averages.For now thedaily trend is still up. The consolidation has broken, but the 200 EMA isprinting a first demand reaction. My question is simple: does a bounce reclaimthe range, or does the former floor, now resistance, cap the buyers before astronger charge?Why Oil Is Falling Today?Oil droppedafter Washington and Tehran agreed to halt a war that erupted in late February,when US and Israeli strikes on Iran's nuclear program shut the Strait of Hormuz in earlyMarch. Officialswill meet in Switzerland on June 19 to sign the text, which neither side hasreleased, according to Bloomberg reporting. President Donald Trump said thestrait would reopen once mines are cleared from the waterway.Before theblockade, the strait handled roughly a fifth of the world's oil supply in amarket of more than 100 million barrels a day. Nearly 600 vessels remain stuckin the Persian Gulf awaiting departure, data firm Kpler told Bloomberg. The unwindalready shows in the futures curve: Brent's prompt spread narrowed to less than$1 a barrel in backwardation, down from more than $12 in April.Caution iswarranted: mines still need clearing, insurers may charge elevated rates, andshut-in Gulf fields could take months to restart, per Reuters and Bloombergcoverage. Trump also warned he could resume strikes if the 60-day talks fail. Volatilityhas run hot enough that brokers rolled out tokenized WTI exposure to capture the flows.The droprests on four shifts:US-Iran interim deal signed June 19 reopens Hormuz, ending an effective blockade of about 20% of global oil flowsBrent backwardation collapsed to under $1 from above $12 in April, signaling eased scarcityRecord reserve draws and softer Chinese imports had already capped prices into the dealFed decision this week, the same inflation math that earlier rippled into Bitcoin after the Hormuz shockGoldman Sachs Cuts Its2027 Oil ForecastGoldmanSachs added a counterintuitive twist on June 12. The bank kept its Q4 2026Brent forecast at $90, holding to near-term geopolitical risk, while cuttingits 2027 average to $80, down $5, according to Reuters reporting. The messageis that the current war premium does not become a lasting price surge.Goldmanpointed to stronger supply from the US, Brazil, Guyana, Venezuela and the UAE,alongside weaker demand tied partly to China's shift to electric vehicles. Thebank assumes just over 10% of the demand lost during the shock sticks. It stopsshort of calling a collapse, because the physical market is still tight, thesame oversupply-versus-scarcity tension I covered when oil slipped after the Madurocapture.US crudeinventories underline that tightness. Stockpiles fell 7.2 million barrels to426.5 million in the latest week, nearly 5% below the five-year average, whiledistillates sat 13% below normal, per Investing data. Oil trading volumes climbed through Q1 as volatilityintensified.The 2027downgrade rests on:Non-OPEC supply growth from the US, Brazil, Guyana, Venezuela and the UAEStructural demand loss, with Goldman assuming over 10% of the shock-driven drop persistsChina EV penetration eroding gasoline and diesel demandStill-tight inventories, which keep Goldman from forecasting a deeper slideHow Low Can Oil Go? OilPrice PredictionsHow low oilcan go depends on whether the Hormuz reopening holds. Goldman's $90 Q4 2026Brent call still bakes in a war premium that is actively draining, so I read itas a ceiling rather than a base if the deal sticks. Its $80 cut for 2027matches my own bias: once Gulf barrels return, the structural surplus reassertsand rallies get sold.Theofficial forecasters agree on direction. The EIA's June outlook sees Brenteasing to $89 in Q4 2026 and averaging $79 in 2027, assuming Hormuz reopens inthe third quarter. JPMorgan is more bearish at $75 for 2027, the lowest of themajors, and that number looks reasonable to me if demand stays soft and USoutput holds near record highs.On mychart, the first WTI support is the $80 shelf, where the 200 EMA, the June 2025highs and the round number converge. Lose it, and $72 from April 2025 opens up.The bull case is a deal collapse: mines, insurance friction or a failed nucleartrack snap the premium back and drive WTI into the $110 to $120 consolidationagain.Bullcase (deal fails, premium returns):Mine-clearing or insurance friction delays Hormuz transits past June 19Iran-Oman control of the strait reignites supply fearsNuclear talks collapse inside the 60-day window, risking renewed strikesBearcase (deal holds, surplus returns):Gulf shut-ins restart, adding back more than 10 million barrels per day of disrupted outputNon-OPEC supply from the US, Brazil and Guyana keeps buildingChina EV demand and record US production cap any reboundFAQ, OIL Price AnalysisWhy is oil falling today? WTI crudefell almost 5% to $80.73 on June 15, 2026, and Brent dropped below $84 afterthe US and Iran agreed to an interim deal to reopen the Strait of Hormuz. Thewaterway carried about a fifth of global oil supply before the war, so itsreopening drains the geopolitical premium that had lifted crude since lateFebruary.How low can oil prices go?Mytechnical analysis puts the first WTI support at the $80 shelf, where the200-day EMA and June 2025 highs converge. A break below it opens $72, the April2025 level. The EIA sees Brent averaging $79 in 2027, while JPMorgan models$75, so a move into the $70s is credible if the deal holds.What is the Goldman Sachsoil price forecast for 2027? GoldmanSachs cut its 2027 average Brent forecast to $80 a barrel on June 12, 2026, a$5 reduction. The bank kept its Q4 2026 Brent call at $90 but expects strongersupply from the US, Brazil, Guyana, Venezuela and the UAE, plus weaker Chinesedemand, to weigh on prices next year.When will the Strait ofHormuz reopen? The US andIran are due to sign their interim deal on June 19, 2026, in Switzerland, afterwhich the strait is set to reopen once mines are cleared. The EIA assumesshipments resume in the third quarter of 2026, with traffic taking until early2027 to return to pre-conflict levels.Is WTI crude still in anuptrend? Yes, fornow. WTI broke its three-month consolidation on June 15, 2026, but the dailytrend remains up while the 200-day EMA near $80 holds. My read hinges onwhether a bounce reclaims the old range or the former floor at $85 to $88, nowresistance, caps the rebound.This article was written by Damian Chmiel at www.financemagnates.com.
