Oil: From A Week-High Of $109.47 To A Friday Low Of $87.11; A $22 Swing In Seven Days That Tells The Entire Story Of How Violently The Global Energy Market Has Been Priced Around One Word: Deal
According to Reuters, CNBC and Investing.com, oil futures fell more than 1% on Friday and were on track for their steepest weekly decline since early April, following reports that the US and Iran had agreed to extend a ceasefire.
Brent crude futures for July fell 1.1%, or $1.04, to $92.67 a barrel. US oil futures fell $1.26, or 1.4%, to $87.64 a barrel. Brent plunged 10.5% this week; the steepest plunge since the week ended April 6 while WTI fell 9.2%, its biggest weekly loss since the week ended April 13.
The US and Iran reached an agreement on Thursday to extend the ceasefire and lift restrictions on shipping through the Strait of Hormuz, sources told Reuters, though US President Donald Trump had yet to approve it and Iranian state media said it had not been finalised.
That caveat is carrying weight. Remarks from Vice President JD Vance that the nations were “close” to reaching a deal but “not there yet” kept a floor under prices, preventing a more severe collapse.
The Strait of Hormuz is the entire story. Prices have been volatile in recent sessions, swinging by as much as $6 for both benchmarks on conflicting signals over a possible end to the three-month Iran war and the potential reopening of the Strait of Hormuz; a key transit route for roughly a fifth of the world’s oil and liquefied natural gas supplies.
When that transit route is open, approximately 21 million barrels of oil pass through it daily. When it is closed or threatened, the global energy system reprices in hours, not days. The $22-per-barrel swing from Monday’s high of $109.47 to Friday’s intraday low of $87.11 is what a fifth of global oil supply held hostage to geopolitical brinkmanship looks like in market terms.
The anatomy of the week. Monday opened with deal optimism already priced in after weekend diplomacy signals, pushing Brent toward $109. Fresh US strikes near the strait mid-week reversed that, triggering a sharp bounce to $99 on Tuesday as the whipsaw described in our earlier coverage played out.
By Thursday, sources confirmed an agreement outline had been reached not yet approved by Trump, not yet confirmed by Tehran, but enough to push prices sharply lower again.
Friday’s session extends that decline but with a measured tone, reflecting what IG analyst Tony Sycamore described as the market’s working assumption: “Consensus remains the conflict is over, and a deal is coming.
As long as this narrative holds, crude oil has room to extend its decline toward trendline support in the low $80s.”
The financial implications are structural, not just directional. A sustained reopening of the Strait of Hormuz does not simply return oil to pre-war prices. The three-month conflict has created supply disruptions that cannot be reversed overnight; upstream production deferrals, tanker route realignments, refinery inventory drawdowns, and the 1.2 billion barrels of disrupted supply documented by S&P Global that were referenced in earlier reporting.
US shale producers locked in capital spending increases of $490 million above pre-war guidance. Those commitments do not reverse on a press release. The market is pricing the direction of travel; lower while acknowledging that the pathway is neither linear nor guaranteed.
The equity and currency side effects are equally significant. S&P 500 futures have been tracking the ceasefire narrative in inverse lockstep with crude; rising as oil falls, as lower energy costs improve the corporate earnings outlook and reduce the inflationary pressure that had been forcing the Fed to hold rates higher than the underlying non-energy economy warranted.
The dollar has shown mild softness against the euro and sterling this week as the safe-haven premium embedded during peak conflict intensity begins to unwind. Airline stocks, petrochemical processors, and consumer discretionary names have all been the quiet beneficiaries of the oil decline, with the gains unreported because the commodity move dominates the headline.
What confirmation of the deal would mean. A Trump-approved, Iranian-confirmed ceasefire extension with Hormuz explicitly reopened would likely push Brent below $85 within 48 hours and test the mid-$70s within weeks as risk premiums fully unwind. At that level, several US shale projects operating on emergency-pace economics become marginal.
Saudi Arabia, which needs oil closer to $90 to balance its 2026 Vision programme budget, faces a very different fiscal equation. OPEC+ would be under immediate pressure to cut production to defend price levels that the political resolution of a conflict has undercut.
What failure of the deal would mean. If Trump does not approve, or if Iran’s state media confirmation that talks remain unfinished becomes the dominant signal, the market has already demonstrated it can reverse $6-$8 per barrel intraday. The $109 ceiling from Monday is not unreachable.
The structural support that kept prices elevated throughout the three-month conflict; blocked strait, disrupted tanker routes, reduced Gulf output has not been physically removed yet. Until ships are actually moving through Hormuz again, the market is trading a narrative rather than a fact.
The verdict for global consumers. If the ceasefire holds and the strait reopens, the energy inflation episode of early 2026 begins to unwind. US gasoline prices, which had been tracking toward $5 per gallon on the CNN projections cited in our earlier coverage, could fall meaningfully into the summer driving season rather than peaking into it.
For Pakistan, where the rupee has been absorbing elevated import costs across both petroleum and its downstream effects on transport and food, a sustained oil decline is a meaningful terms-of-trade improvement.
For Europe, already managing the tail end of the 2025 heat mortality crisis documented earlier this week, lower energy prices ease the fiscal pressure of energy support programmes heading into summer.
The market is pricing a deal. Trump has not yet signed it. Until he does, every session carries the risk of a violent reversal in either direction. To check out our previous coverage on the US-Iran conflict and global oil markets, read our articles here.
