Hungarian Prime Minister Viktor Orbán is on a collision course with the European Union after threatening to torpedo a €90 billion ($103 billion) loan for Ukraine, a move officials say could trigger a post-election crackdown on Budapest.

Orbán, who had previously signed off on the funding, is now using the threat of a veto to block the package ahead of an EU summit – escalating tensions as Kyiv presses for urgent financial support.

Diplomats told Politico that the reversal has “crossed a red line,” with patience in Brussels rapidly evaporating. Several member states are now weighing punitive options, including stripping Hungary of voting rights or tightening access to EU funds – a step the EU has long hesitated to take.

“This cannot continue,” one senior diplomat said.

At the center of the dispute is the Druzhba pipeline, a key route delivering Russian oil to Hungary. Budapest has cited disruptions to the pipeline – which Kyiv says were caused by Russian strikes – as justification for blocking the funding, effectively linking Ukraine’s financial lifeline to its own energy security concerns.

Behind closed doors, the tone has already hardened. German Foreign Minister Johann Wadephul warned Hungary its obstruction “can no longer be tolerated,” according to diplomats briefed on the talks.

European Council President António Costa, who leads engagement with Viktor Orbán ahead of EU summits, signaled a tougher approach in a Feb. 23 letter.

In it, Costa warned that by withdrawing support for the loan, Orbán had violated the EU’s principle of sincere cooperation, potentially opening the door to legal consequences.

So far, however, Brussels has stopped short of direct confrontation.

That restraint is largely tied to Hungary’s upcoming election. Orbán faces a serious challenge from opposition figure Péter Magyar and is trailing in some polls.

EU officials are wary of taking aggressive action before the vote, fearing it could bolster Orbán’s narrative of foreign interference.

Still, diplomats say a reckoning is inevitable – and may come quickly after the election, regardless of the outcome.

If Orbán secures another term, EU capitals are expected to move more decisively to curb his ability to block key decisions. If Magyar prevails, leaders may initially adopt a wait-and-see approach.

For now, EU leaders face a dilemma: push ahead with the Ukraine loan and risk a public veto showdown with Orbán, or delay the package and risk delaying crucial aid to Kyiv at a critical moment.

“There is clear reluctance to give Orbán the spotlight,” one diplomat told Politico. “But if we fail on the loan, Zelensky will rightly be furious.”
