Today’s Focus
Oil-linked assets rose on Tuesday 13 October. The USO fund, which holds US crude-oil futures, gained 1.36% to US$153.09.
Ecopetrol, Colombia’s state-controlled producer, rose 1.68% in New York. In São Paulo, Petrobras gained 1.52% and PRIO, a Brazilian offshore producer, 3.58%.
InfoMoney said US-Iran tension stayed in focus for markets. Oil shares rose even as Brazil’s broad index fell.
What matters today. Oil is rising for a second day, which lifts producers across Latin America and also feeds petrol prices in the United States.
01 The session in one read
The USO fund rose 1.36% to US$153.09 on Tuesday 13 October. It is up 3.30% in two sessions from Friday’s US$148.20.
Oil producers outperformed the market in São Paulo. Petrobras and PRIO rose while the Ibovespa fell 1.04%.
Oil funds and producers rose together, and the geopolitical backdrop was in focus. We could not confirm the price driver or OPEC’s forecasts.
The variable to watch is whether the USO fund holds above US$150. A close below it would erase much of the two-day gain.
02 The board
The fund and most producers rose together. YPF’s New York ADR was the exception, down 0.35%, although its Buenos Aires shares rose 3.29%.
The USO fund is a proxy for US crude futures. It is not the price of Brent or WTI itself.

03 What moved it
InfoMoney named US-Iran tension as a theme that stayed on investors’ radar. We could not confirm a single oil-price driver for the day.
OPEC’s monthly oil market report was scheduled for Tuesday 13 October, according to RT’s calendar. We could not confirm its forecasts by our deadline, so we do not quote them.
04 The Latin American read
Argentina’s Vaca Muerta, Brazil’s pre-salt fields, Colombia’s Ecopetrol and Guyana’s offshore boom all sell into the same global price. Higher oil helps their exports and tax take.
For US readers, the same rise can lift petrol prices at home. That matters well beyond the producers.
05 The names to watch
YPF is the clearest US-listed bet on Argentina’s shale. Petrobras is the largest producer in Latin America.
Ecopetrol links Colombia’s budget to the oil price. Its ADR gained 1.68%.
What Prediction Markets Say
Polymarket, a prediction market, priced crude oil setting a new all-time high by 31 December at 10.5%, with US$1,810,742 traded on that market (read at 8:50 pm ET on 13 October).
These prices are bets on a record price, not forecasts.
Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
06 The outlook
Traders will watch for fresh shipping incidents, the content of OPEC’s report and any change in OPEC+ policy. We could not confirm the settle of Brent or WTI futures for Tuesday, so we quote the USO fund only.
US inflation data on Wednesday 14 October could move the dollar and with it oil. A second strong day would extend a sharp two-session rise.
07 What to watch
- OPEC’s report: Its demand and supply forecasts will frame the next move.
- Shipping and Iran headlines: New incidents would add a risk premium.
- US consumer prices: The September reading is due on Wednesday 14 October at 12:30 UTC (8:30 am ET).
- The US$150 line on USO: A close below it would erase much of the two-day gain.
Background: Oil Fund Jumps 1.91% as YPF Rises 3.86%.
