A group of economists said the unlikely acceleration of Poland adopting the euro could be the game-changer needed to break the impasse.
Economics professor Witold Orłowski said the move could bring an end to a row over judicial reform in Poland which EU officials insist is in breach of European law.
He said the move would further the integration Warsaw craved and reassure Poles who are becoming increasingly concerned about being marginalised by traditional EU powerhouses France and Germany.
Mr Orłowski said: “This appeal isn’t completely senseless. There is a chance it could have an effect.”
The professor also said Poland’s news PM Mateusz Morawiecki was “generally a rational person” who would warm to the suggestion once the benefits became clearer.
Mr Morawiecki, a former banker who was a member of the economic council advising Donald Tusk when he was the Polish prime minister, had earlier distanced himself from the euro.
He told the ultra-Catholic Radio Maryja station: “We’re certainly not racing to the eurozone.”
Poland has clashed with the European Commission in recent months over immigration and the rule of law.
Warsaw is currently facing the Commission’s “nuclear option”, Article 7, which would strip the country of its Brussels voting rights, due to a government move to strip away the independence of the judiciary.
Poland has also become embroiled in a new row over immigration has with Mr Morawiecki and his Hungarian counterpart, Viktor Orban, reaffirming their countries’ hardline stand by refusing to accept EU quotas.
But the new leader insists he wants to play a leading role within the bloc.
Mr Morawiecki said: “I believe that similarly-minded nations like ourselves together can influence Europe’s future in a very positive way.”
He said Central European countries like Poland and Hungary would begin by presenting a common front in budget negotiations.
