Oil Wrap: USO Hits US$129.17, Petrobras Rises, Ecopetrol Falls
Key Facts
- WTI’s tracking fund USO closed at US$129.17, up 1.33% extending a rally driven by tighter supply expectations and persistent geopolitical risk in shipping lanes.
- Stronger crack spreads supported the move reflecting higher US Gulf Coast refinery margins that bolster integrated producers’ cash generation.
- Petrobras shares rose 1.46% to US$19.40 as firmer crude highlighted the appeal of Brazil’s low-cost, long-lived pre-salt barrels.
- Argentina’s YPF advanced 0.75% to US$52.54 tracking the oil price and an improved local backdrop, signalling cautious optimism for Vaca Muerta drilling.
- Colombia’s Ecopetrol dropped 1.58% to US$16.77 bucking the regional trend as investors weighed policy debates on new exploration and taxation.
- Guyana’s offshore boom remained a focal point with higher WTI levels enhancing the economics of future floating production units in the Stabroek block.
Today’s Focus
Crude’s summer advance continued on Friday, with the US Oil Fund, the exchange-traded vehicle tracking WTI, settling at US$129.17 for a 1.33% daily gain. The move reflected a market pricing tighter physical supply, steady global demand, and lingering threats to shipping lanes.
Brazil’s state-controlled giant Petrobras rode the wave, its New York shares climbing 1.46% to US$19.40. Investors treated the stock as a liquid way to bet on high oil prices via the company’s prolific and comparatively cheap pre-salt deepwater fields.
Argentina’s YPF also participated, closing 0.75% higher at US$52.54, as the rally in crude strengthened the investment case for the Vaca Muerta shale formation despite the country’s chronic capital controls. Bucking the trend, Colombia’s Ecopetrol slid 1.58% to US$16.77, punished by domestic political debates that have clouded its exploration future.
What matters today. Strong crude prices are a rising tide, but they cannot lift boats anchored by country-specific political and policy risks, as Ecopetrol’s drop made clear.

01 The session in one read
Latin America’s energy complex mostly climbed alongside global crude benchmarks on Friday, with the US Oil Fund closing at US$129.17 for a 1.33% advance. The rally stemmed from a market narrative focused on tightening supply and steady demand, amplified by geopolitical friction that threatens tanker routes.
Brazil’s Petrobras rose 1.46% to US$19.40 and Argentina’s YPF added 0.75% to US$52.54, directly benefiting from the stronger tape. The clear exception was Colombia’s Ecopetrol, which fell 1.58% to US$16.77 as homegrown policy debates overshadowed the commodity’s upward march.
The session painted a clear picture: higher WTI, as tracked by USO’s rise to US$129.17, acts as a powerful tailwind for well-managed, low-cost Latin American producers. Petrobras and YPF moved in lockstep with crude, while Guyana’s break-even economics look ever more attractive. The outlier, Ecopetrol’s 1.58% decline to US$16.77, proves that political and regulatory uncertainty in Colombia is currently outweighing the benefit of a US$129 oil price. The key variable to watch is any formal change to Colombia’s exploration licensing policy, which could deepen Ecopetrol’s disconnect from the crude tape.
02 The board
The US Oil Fund’s settlement at US$129.17, a gain of 1.33%, set the tone, acting as the session’s primary bullish signal for global investors. This filtered through directly to Brazil, where Petrobras shares hit US$19.40, up 1.46%.
Argentina’s YPF tracked the move with a 0.75% rise to US$52.54, while Colombia’s Ecopetrol diverged sharply, dropping 1.58% to US$16.77. The mixed board underscored how national stories are now heavily mediating what is otherwise a straightforward rally in the crude proxy.

03 What moved it
Stronger US Gulf Coast refinery margins and improved crack spreads—the profit difference between buying crude and selling refined fuel—provided fundamental support, boosting integrated producers. These margins signal healthy demand and efficient processing, which flowed directly into the US Oil Fund’s up-day.
Persistent geopolitical risk in key shipping lanes added a supply-security premium, while broader market expectations of constrained output kept a floor under prices. This combination of physical market tightness and logistical fear pushed the WTI proxy past US$129.
04 The Latin American read
Brazil’s pre-salt remains the region’s most direct beneficiary of a price surge. Foreign investors viewed Petrobras, with its vast, low-lifting-cost offshore fields, as a reliable ‘liquid beta’ to the WTI proxy, pushing its shares up 1.46% to US$19.40.
In Argentina, YPF’s 0.75% rise to US$52.54 reflected cautious optimism that sustained high oil prices can underwrite the huge drilling requirements of the Vaca Muerta shale, with an improved local macro backdrop providing a secondary lift. Guyana’s offshore sector, led by ExxonMobil, saw its long-term economics brighten, with USO’s rally supporting the case for new multi-billion-dollar floating production units.
05 The names to watch
Colombia’s Ecopetrol was the session’s stark warning, its shares sinking 1.58% to US$16.77. This was a clear instance of country risk overriding commodity momentum, as investors priced in the uncertainty from official debates on banning new exploration and adjusting taxation.
Mexico’s Pemex remains a credit story, where higher oil revenues from the rally improve short-term budget relief but fail to solve structural problems of ballooning debt and refining losses. In Venezuela, a potential policy shift is monitored as the sole catalyst that could reconnect its massive heavy-oil resources with global capital.
06 The outlook
The path for Latin America’s oil names will be a tug-of-war between a robust global pricing environment and homegrown political risks. The US Oil Fund’s US$129.17 print is a powerful accumulator of value for Petrobras and YPF, but for Ecopetrol and Pemex, it merely buys time against fiscal and regulatory headwinds.
07 What to watch
- Crack spreads and refinery margins: Watch to see if the strong product demand that lifted USO to US$129.17 holds, confirming cash generation for integrated producers like Petrobras.
- Colombia’s exploration policy: Any formal government announcement on new licensing could rapidly move Ecopetrol further, having already sent it down 1.58% to US$16.77.
- Vaca Muerta infrastructure: YPF’s modest 0.75% rise to US$52.54 could accelerate if new midstream capacity eases export bottlenecks, unlocking higher wellhead netbacks.
- Guyana FPSO sanctioning: With WTI elevated, a green light for the next ExxonMobil-led floating production unit would cement the country’s status as a non-OPEC supply powerhouse.
Frequently Asked Questions
Why did Petrobras shares rise?
Petrobras closed 1.46% higher at US$19.40, directly lifted by the US Oil Fund’s 1.33% gain to US$129.17, as its low-cost pre-salt barrels become more profitable in high-price environments.
Why did Ecopetrol fall against a strong oil tape?
Ecopetrol dropped 1.58% to US$16.77 because policy risk in Colombia, including debates over halting new exploration, is overriding the benefit of higher crude prices for the state-run company.
What is the WTI crude proxy?
The US Oil Fund, which closed at US$129.17 up 1.33%, is an exchange-traded fund that tracks the price of West Texas Intermediate crude, giving equity investors a direct read on the oil market.
Is the Vaca Muerta boom still on track?
Yes, YPF’s 0.75% gain to US$52.54 signals cautious confidence that sustained high oil prices will continue to fund drilling in the Argentine shale formation, despite ongoing capital controls.
