West Texas Intermediate crude prices staged a sharp rally on Friday, extending the upward momentum that has gripped energy markets following the formal enforcement of a US naval blockade against Iranian vessels.

The move signals that traders are increasingly pricing in sustained supply constraints from the Strait of Hormuz, with the risk premium broadening across the complex.

The rally in benchmarks triggered a positive reaction across Latin American energy equities.

Shares of major producers, including Brazil’s Petrobras and Argentina’s YPF, climbed in tandem with the oil price surge.

The cross-asset move highlights how regional investors are recalibrating valuations in response to the geopolitical tightening of global supply routes, particularly for producers with exposure to pre-salt reserves and emerging basins like Guyana.

This development follows a volatile week for crude markets.
