Oil Wrap: WTI Proxy Steady as LatAm Supply Shifts

01 The session in one read

Crude’s main US-listed proxy finished Friday, August 21 essentially where it started. USO closed at US$134.64, a gain of just 0.07%, while the front-month WTI futures contract settled at US$87.06 per barrel, up about 0.3%.

That flatness came from two forces pulling in opposite directions. The Strait of Hormuz saw transits in single digits for the entire week amid Washington’s ‘Economic D-Day’ campaign against Iran, yet Iraq’s prime minister chose Friday to announce a target of 8 million to 10 million barrels per day within six years.

Latin American oil equities mostly took their own cues. Petrobras rose, YPF rose, and Ecopetrol fell, while the deeper news sat in Guyana, Mexico and Argentina’s shale.

02 The board

Petrobras New York shares added 0.74% to US$19.15, the strongest of the four Latin American names on this board. YPF was close behind at US$51.18, up 0.51%, as investors digested fresh Vaca Muerta spending and export plans.

Ecopetrol was the outlier, down 0.68% to US$17.53. The Colombian producer’s dip ran against the regional grain on a day when most oil-linked proxies held firm.

USO’s 0.07% drift to US$134.64 is a reminder that the fund tracks WTI futures exposure rather than a single physical barrel, so its daily move can diverge slightly from the front-month contract’s 0.48% decline.

Geopolitics did the heavy lifting but cancelled itself out. Hormuz remained nearly shut to tanker traffic all week, which would normally lift crude, yet Baghdad’s stated plan to double Iraqi output injected a supply-side counterweight.

Baghdad wants OPEC to release it from quota constraints, and dispatched its oil and finance ministers to make that case. The market heard that as a bearish signal for future barrels, even if the immediate headline was about Iranian disruption.

Friday’s Baker Hughes rig data showed US oil rigs falling by 3 to 452, with total oil and gas rigs at 588. That was a modest pullback consistent with drillers responding cautiously to a market still trying to price both blockade and expansion.

04 The Latin American read

Guyana’s shift into the profit-oil phase is now explicit: the ExxonMobil-led Stabroek venture has recovered roughly US$55 billion of investment since 2014, and Georgetown says it is entitled to 39.8% of production under the revised formula.

That number matters because the original 2016 deal had split the post-cost barrels far less generously. With seven projects sanctioned and Yellowtail ramping up, Guyana is becoming a swing supplier that can cushion Exxon against declines elsewhere.

Argentina’s YPF is converting gas ambition into paperwork: a US$51 billion integrated LNG export project with Eni and XRG is now before the RIGI incentive regime. YPF also locked in Halliburton’s Zeus electric fracturing fleet, the first deployment outside the United States, for a fourth-quarter start.

Mexico features the most speculative story: Pemex and Petrobras are reportedly combining expertise to drill far older source rocks in Mexican Gulf waters. It is a high-risk, high-reward exploration bet that fits both state companies’ need to replace reserves.

05 The names to watch

Petrobras is the immediate beneficiary of the Pemex deepwater chatter. Its New York shares at US$19.15, up 0.74%, reflect a market that sees Brazilian deepwater know-how as an exportable asset.

YPF’s 0.51% rise to US$51.18 follows a busy August: raised capex guidance to US$5.8-6.2 billion, projected about US$8 billion EBITDA, and targeted Vaca Muerta shale oil exit rates near 250,000 barrels per day by year-end.

Ecopetrol’s 0.68% decline to US$17.53 leaves it as the board’s laggard. The Colombian producer has no equivalent to Guyana’s profit-oil milestone or Argentina’s LNG pipeline, leaving it more exposed to the global crude tape.

06 The outlook

The week ahead hinges on two questions: whether OPEC gives Baghdad any quota relief, and whether Hormuz transits recover from single digits. The first would loosen the market’s supply anchor; the second would tighten it sharply.

For Latin America, the more durable signals are structural: YPF’s pipeline is about 80% complete with first oil expected by early 2027, and Guyana’s government has set aside 20% of production in a revised formula to cover ongoing costs now that capital recovery is done.

07 What to watch

• OPEC stance on Iraq: Any signal that Baghdad gets quota relief would undercut the Hormuz risk premium and pressure all Latin American oil proxies.
• Strait of Hormuz transits: A recovery to normal tanker counts would remove the week’s main bullish catalyst, while another single-digit week would lift USO.
• Vaca Muerta logistics: YPF’s Vaca Muerta Oil Sur pipeline progress and first oil timing toward early 2027 could move YPF shares more than crude itself.
• Guyana profit-oil split: Confirmation of the new 39.8% entitlement and Exxon’s forward drilling plans could reprice the basin’s economics for foreign investors.

Frequently Asked Questions

Why did oil barely move on Friday?

Hormuz disruption supported prices, but Iraq’s announcement that it wants to more than double output within six years supplied a bearish offset, leaving USO up just 0.07% at US$134.64.

Why does Guyana matter for oil markets now?

ExxonMobil has recovered about US$55 billion in Stabroek investment, moving the project into its profit-oil phase where Guyana’s entitlement rises to 39.8%.

What is YPF doing in Argentina?

YPF and partners Eni and XRG have submitted a US$51 billion ‘Argentina LNG’ project under the RIGI scheme, while the Vaca Muerta Oil Sur pipeline is about 80% complete.

Why is Ecopetrol falling while Petrobras and YPF rise?

Ecopetrol lacks the deepwater partnership catalyst Petrobras has with Pemex and the LNG story YPF has in Vaca Muerta, leaving it more exposed to the flat crude tape.
