Oil Falls Despite Hormuz Shock; Petrobras Drops 3%
Key Facts
- The USO fund, which tracks WTI crude, closed at US$117.98 a share on Friday, slipping 0.75% as traders looked past the closure of the Strait of Hormuz towards a potential peace deal.
- Petrobras shares dropped 3.02% to US$17.96, the steepest decline among the region’s majors, hit by the global bearish tilt and the drag from a stronger U.S. dollar.
- Colombia’s Ecopetrol fell 3.56% to US$16.78, pacing the sector’s losses as the bearish macro mood outweighed record American crude production helping to plug the supply gap.
- Argentina’s YPF lost 0.91% to US$49.16, showing relative strength as the Vaca Muerta shale play distances itself from offshore geopolitical risk.
- Oil traders remained broadly bearish despite the expansion of conflict to the Red Sea, with Brent well below its wartime highs on bets of a quick ceasefire.
- The Trump administration is weighing another suspension of the Jones Act, hoping to lower domestic gasoline prices that remain above US$4 a gallon ahead of midterm elections.
Today’s Focus
Oil prices fell on Friday, August 7, 2026, driven by a stubbornly bearish trading consensus that expects a swift diplomatic resolution to the Middle Eastern conflict that has sealed off the Strait of Hormuz. The United States Oil Fund (USO), which tracks WTI crude, closed at US$117.98 a share, down 0.75% on the day. That is the fund’s share price, not a barrel price.
The decline weighed heavily on Latin America’s state-controlled producers. Brazil’s Petrobras slumped 3.02% to US$17.96, Colombia’s Ecopetrol dropped 3.56% to US$16.78, and Argentina’s YPF gave back 0.91% to close at US$49.16.
The bearish sentiment persisted even as shipping lanes in the Red Sea remained active war zones and the Jones Act waiver debate signalled political unease over sustained high pump prices. Record U.S. crude volumes have cushioned the global supply shock, but the region’s oil equities are failing to decouple from the downward macro momentum.
What matters today. The market is pricing a peace premium rather than a war premium, and Latin America’s oil stocks are following global sentiment lower despite tight physical supply.
01 The session in one read
Crude prices slipped Friday, August 7, 2026. The slide extended a week-long decline that puzzled observers.
The Middle Eastern conflict was expanding, yet traders held firm. They believe a diplomatic breakthrough is near.
The WTI-tracking USO fund closed at US$117.98 a share. That marked a 0.75% daily decline.
The drop hit Latin America’s oil producers hard. A stronger U.S. dollar and deeper risk-off mood fueled the rout.
Petrobras led with a 3.02% fall to US$17.96. Ecopetrol tumbled 3.56% to US$16.78.
YPF slipped a modest 0.91% to US$49.16.
Oil equities are trading as if the Strait of Hormuz has already reopened, a scenario that leaves them vulnerable to a violent repricing if peace talks fail. While American production records are helping refiners replace lost Middle Eastern barrels, the paper market has detached from the physical reality of disrupted supply chains. The variable to watch is whether Brent crude can hold its recent range if ceasefire negotiations stall.
02 The board
Every major Latin American oil proxy on our board finished in the red. The heaviest blows landed on Caribbean-facing drillers.
Petrobras at US$17.96 and Ecopetrol at US$16.78 each lost more than 3%. They moved in lockstep with a flattened futures curve despite the Strait of Hormuz supply crisis.
Argentina’s YPF was the session’s resilient outlier. It eased just 0.91% to US$49.16.
Foreign investors now view the Vaca Muerta-adjacent stock as a landlocked oil story. This insulates it from maritime choke points.
That distinction gives YPF defensive status in a jittery market.

03 What moved it
The overriding driver was the futures market’s stubborn bet on a peace deal. Despite the expansion of hostilities to the Red Sea and the physical closure of the Strait of Hormuz, Brent has retreated hard from its conflict-driven peak, a signal that traders see the current disruption as temporary.
On the supply side, record-breaking American crude production and surging LNG exports have absorbed much of the shock, giving Asian and European refiners a workable, if expensive, alternative to Middle Eastern barrels. In Washington, President Trump’s renewed threat to waive the Jones Act underscored the political pressure from gasoline prices above US$4 a gallon, yet the move is widely seen as symbolic because coastwise shipping accounts for a small slice of final fuel costs.
04 The Latin American read
Brazil’s pre-salt fields and Petrobras are being swept along by global macro currents rather than local fundamentals. The 3.02% slide in Petrobras shares to US$17.96 reflects a broader exit from emerging-market state oil companies as funds reassess the risk that a peace deal could erase the supply-driven price floor.
In Guyana, which does not trade on our board directly, the Exxon-led Stabroek block boom continues to attract capital even as the paper market wobbles, because its low break-even costs and proximity to the U.S. Gulf Coast make it a natural hedge against Hormuz risk. Mexico’s Pemex and Argentina’s Vaca Muerta story, meanwhile, are moving in opposite directions: Pemex’s heavy crude discount is widening again, while YPF’s tight 0.91% slip suggests the market is rewarding companies with export pipelines that bypass the Panama Canal and the Hormuz chokepoint entirely.
05 The names to watch
Petrobras remains the bellwether for the region, and its 3.02% single-session drop to US$17.96 suggests foreign portfolio money is reducing exposure ahead of any ceasefire announcement that would release Iranian and Iraqi barrels back into the market.
Ecopetrol’s 3.56% fall to US$16.78 makes it the worst performer among our tracked proxies, a move amplified by Colombia’s broader peso weakness and the market’s punishing view of companies with higher lifting costs. YPF, at US$49.16, is the only name on the board holding a constructive chart setup, having absorbed the Hormuz crisis as an accelerant for long-dated Vaca Muerta offtake deals rather than as a reason to sell.
06 The outlook
The week ahead hinges on peace-tracker headlines and the delayed physical impact of a still-shut Strait of Hormuz finally showing up in inventory data. If diplomatic progress stalls, the sudden rerating of oil equities could be violent, given how aggressively short positions have been built. For Latin American producers, the added wildcard is whether the Jones Act debate signals a broader U.S. sprint toward energy self-sufficiency that reshapes the competitive landscape for imported crude.
07 What to watch
- Peace talk headlines: Any verified progress toward a ceasefire will likely depress crude prices further, while a breakdown could trigger a short-squeeze that lifts the entire Latin American oil board.
- U.S. inventory data: The first official stockpile reports fully reflecting the Hormuz closure will reveal whether the physical market is as amply supplied as the paper market believes.
- Petrobras dividend posture: The steep 3.02% drop to US$17.96 raises the question of whether management will defend the stock with an extraordinary shareholder distribution or conserve cash for pre-salt capex.
- YPF’s Vaca Muerta offtake deals: The stock’s 0.91% retreat belies the flurry of contract negotiations with Asian buyers seeking non-Middle Eastern supply; any signed agreement could decouple YPF further from the global sell-off.

Frequently Asked Questions
Why did oil prices fall if the Strait of Hormuz is closed?
Traders have bet heavily on a quick peace deal that would restore Iranian and Iraqi crude flows. That has kept bearish pressure on WTI, tracked by USO, whose tracking fund USO slipped 0.75% to US$117.98 a share on Friday.
Why did Petrobras drop more than 3% in a single session?
Petrobras shares fell 3.02% to US$17.96 as global fund managers reduced exposure to emerging-market oil stocks ahead of a potential ceasefire, and a strong U.S. dollar added to the selling pressure.
How is Argentina’s YPF performing differently from other Latin American oil stocks?
YPF shed only 0.91% to US$49.16 because its Vaca Muerta shale assets are landlocked and insulated from Middle Eastern maritime chokepoints, making the stock a defensive play for foreign investors.
Does suspending the Jones Act actually lower U.S. gasoline prices?
Possibly, but the effect is limited. Waiving the Act allows cheaper foreign vessels to move oil between U.S. ports, yet coastwise shipping is only a small fraction of total fuel costs above US$4 a gallon.
