Russian President Vladimir Putin has acknowledged for the first time that the country is facing fuel shortages, a significant admission that underscores the deepening strain on domestic energy infrastructure.

The comments emerged as Ukraine intensified its drone campaign, setting fire to a major oil refinery in southern Russia on Sunday.

Russian authorities confirmed the attack resulted in at least two fatalities, marking a further escalation in Kyiv's targeting of Moscow's energy production capabilities.

The combination of physical damage to refining capacity and the Kremlin's public admission of supply constraints has heightened risk premiums in global energy markets.

Traders are closely monitoring the potential for these domestic shortages to spill over into export flows, particularly given Russia's role as a key supplier to Asian and European markets.

The strike on the southern facility adds to a growing list of operational disruptions that threaten to tighten global supply balances.
