Hungarian Prime Minister Viktor Orban warned Friday that the European Commission’s planned oil embargo against Russia is a “nuclear bomb” for Hungary’s economy.

If accepted, the embargo will abolish utility pricing controls, and fuel costs might reach 700 to 800 forints (1.94-2.22 USD) per litre, according to Orban, who spoke to local public radio MR1.

In Hungary, household energy rates were frozen at 2014 levels, while the Orban administration set a 480 forint ceiling on gasoline and diesel prices per litre last year.

Leaders of the European Union (EU) have previously agreed that only steps should be taken that take into account member states’ differing energy structures and sovereign rights to determine their energy mix, but Orban claims that the president of the EC has challenged the great difficulty of achieving European unity.

To replace Russian oil, Orban said, the Hungarian energy infrastructure would have to be transformed over many years and cost thousands of billions of forints.

The imposition of sanctions is not a suitable answer, but Hungary’s veto on the most critical topics, in our opinion, must be preserved,” he stated.

Orban stated that he was prepared to agree the first five sanctions packages, but that the energy embargo would be a no-no.

According to European Commission President Ursula von der Leyen, who unveiled the sixth package of sanctions on Russia, the EU will phase out Russian crude oil within six months and refined goods by the end of the year. 1 forint equals 0.0028 US dollars
