European gas reference prices continued to fall on Friday, heading for the third week in a row, following worries about a drop in supplies from Russia, Bloomberg reports.

On the Amsterdam Stock Exchange, gas futures quoted for delivery in July showed a 3% drop on Friday morning, to 87.71 euro for a Megawatt-hour, while for contracts with delivery in June, which expires on Monday, there was a decline of 3.8%, after a decline of 2.4% on Thursday.

Traders expect gas supplies from Russia to remain stable on Friday, although flows through Ukraine remain sluggish due to the war, according to Agerpres.

On April 27, Gazprom completely shut down natural gas supplies to Poland and Bulgaria in the absence of ruble payments from the two countries. Since then, fears about how EU companies can pay for Russian gas supplies without violating sanctions imposed on Russia by the EU bloc have eased. EU companies have found ways to meet Moscow’s requirements without violating sanctions.

Europe has increased imports of liquefied natural gas (LNG) to cope with declining Russian supplies. On the mainland, gas supplies from import terminals have reached their highest level in five years.
