International oil prices persist on Thursday, exceeding 87 dollars a barrel.

The average price of lead-free in Greece is 1.956 euros per liter, with the highest prices recorded in the Cyclades where they exceed 2.2 euros per liter.

Meanwhile, potential strike action at three major liquefied natural gas facilities in Australia could disrupt about 10% of world exports of fuel and cause another shock to energy prices across Asia and Europe.

Natural gas in Europe jumped as much as 40% on Wednesday. Benchmark futures also briefly topped €40 per megawatt hour for the first time since June, although they are still down more than 80% from unprecedented levels reached in August last year.

The strikes could lead the prices to 50 euros for the rest of the northern hemisphere summer and up to 97 euros in winter, according to Goldman Sachs.
