Brent crude futures climbed in early trading as reports emerged of a Ukrainian military strike on an oil terminal in St. Petersburg.
The incident, which occurred in the early hours of July 4, marks a significant escalation in the targeting of Russian energy infrastructure, reigniting concerns about potential supply disruptions in the region.
The price move reflects the market's sensitivity to physical risks in key producing areas.
While the immediate volume impact of the St. Petersburg strike remains unclear, the event reinforces the structural vulnerability of Russian export logistics.
Traders are likely to maintain a risk premium on crude benchmarks until the extent of any operational damage is assessed.
This development follows a pattern of reciprocal strikes on energy assets, including recent Russian attacks on fuel infrastructure in Ukraine's Dnipropetrovsk region.
