The government is due to announce plans to cut excise on fuel from midnight tonight.
Ministers will hold an emergency meeting later to sign off on plans that would see a 15 to 20 cent reduction on a litre of petrol and diesel.
However, it's feared any reduction could be cancelled out, as oil prices spiral globally due to the war in Ukraine.
The price of petrol and diesel reached 2-euro a litre in many forecourts this week.
Sinn Fein Finance Spokesperson, Pearse Doherty is calling for the government to intervene to maintain the price of fuel at 1-75 a litre for the coming months.
