## Oil prices fall
West Texas Intermediate futures fell 1.2% to US$90.40 a barrel on Friday 9 October, and Brent futures fell 1.3% to US$102.91.
## Trump's statement
President Donald Trump said the United States would not attack Iran before the 3 November midterm elections.
## Market reaction
Petrobras shares rose 2.47% to US$25.30 in New York, while Ecopetrol was flat at US$16.94 and YPF gained 0.28% to US$50.04.
## Oil fund movement
The oil fund USO rose 0.42% to US$148.20, a different move from WTI because the fund holds futures and can diverge from the spot price.
## Prediction markets
Polymarket gives 66.5% to WTI touching US$95 in October and 34.5% to US$100 (US$1.56 million traded).
## Latin American impact
Lower prices help importers like Chile but trim revenue for exporters such as Brazil, Colombia and Mexico.
## Why prices fell
The price drop comes from a political promise, not a change in supply.
## Market assessment
A pause, not an end to the risk premium, Brent still trades above US$100.
## What moved it
Trump's pledge eased fears of disruption to shipping through the Strait of Hormuz.
## Petrobras reaction
Petrobras shares rose in New York even as crude prices fell, suggesting investors reacted to Brazil's market record rally.
## What to watch next
Iran talks, Gulf supply updates, and Petrobras shares could move further.
## Key takeaway

Oil prices fell 1.2% to US$90.40 per barrel after Trump said the US would not attack Iran before the November midterms.
