The European Union (EU) and G-7 countries imposed price restrictionson Russian oil. A price cap application was started for Russian oil transported by sea. In this context, a ceiling price of 60 dollars per barrel was applied to Russian oil. The price cap decision increased tanker density in the Bosphorus, prompting tankers to form a queue off the strait.

The Turkish authorities, on the other hand, required documents from insurance companies that the ships passing through the straits were fully insured as a precaution, reports said.
