Commentary

Refinery Attacks Continue

bullish

Ukraine struck Saratov refinery in southwestern Russia, continuing the pattern of attacks on energy infrastructure. These disruptions to Russian refining capacity could affect regional product flows and crude demand patterns. The persistence of such attacks suggests ongoing volatility in regional supply chains.

Canadian Oil Sands Face Wildfire Risk

bullish

Wildfire season returns to Canada's oil sands region, potentially threatening production facilities. Historical precedent shows significant output disruptions when fires approach major extraction sites. Current dry conditions and seasonal patterns suggest elevated risk through summer months for this key heavy crude supply source.
