The one-year window granted by the US is nevertheless a valuable respite for Hungarian households this winter.
Orban told pro-government reporters who travelled with him to Washington that otherwise utility bills "could have gone up by up to three times in December". Capping those bills by various means has been a central plank of his popularity in Hungary since 2013.
Under the US exemption, Hungary can also continue to buy Russian gas through the Turkstream pipeline, which traverses the Balkans, and pay for it in hard currency ($185m in August alone) using a Bulgarian loophole. Orban has agreed to buy LNG from the US worth $600 million, according to Bloomberg.
Another key part of the Washington deal is nuclear.
Hungary agreed to buy US nuclear fuel rods for its Paks 1 nuclear power station (at a cost of $114m), in parallel to those bought from Russia's Rosatom and France's Framatome.
Russian plans to finance and build the nuclear extension, called Paks 2, have been long delayed by technical and licensing issues. The US agreement to lift all nuclear sanctions on Hungary may help restart that project, but thorny problems remain.
Hungary has also agreed to buy US technology to extend the short-term storage of spent nuclear fuel at Paks for between $100m and $200m.
