European Union foreign policy chief Kaja Kallas confirmed on Saturday that member states have not yet reached an agreement on the bloc's 21st sanctions package against Russia.
The delay in finalizing the measures, which aim to add approximately 250 new listings, underscores the persistent diplomatic friction within the EU as it seeks to tighten its economic stranglehold on Moscow.
The lack of a finalized deal maintains a layer of uncertainty in European energy markets.
With the sanctions package still under negotiation, traders are left without clarity on the specific restrictions that may target Russian energy exports or related financial instruments.
This ambiguity sustains a risk premium in natural gas and oil markets, as investors price in the potential for further supply disruptions or regulatory hurdles.
EU member states have been in the final stages of negotiations for some time, with the primary objective of preventing an automatic and significant increase in Russian revenue from energy sales.
