TTF settled €41.12/MWh on 17 June, the day Regulation (EU) 2026/261's short-term pipeline gas import ban bound, with no snap-back toward €501. TTF is the Dutch Title Transfer Facility, Europe's benchmark wholesale gas price; the ban prohibits short-term Russian pipeline imports while exempting long-term contracts. The benchmark fell on the binding date rather than spiking, extending the slide from the €43.8 first sub-EUR-46 settlement of 15 June.
Two bearish drivers pushed the same way. There was no gas-for-power bid defending the prompt while the spark spread sat negative through the binding session, removing the thermal demand that would otherwise have supported price. And the Iran risk premium that had pinned €50 as a ceiling since late May drained as the US-Iran memorandum, due for formal signing in Switzerland on 19 June, moved to reopen the strait of Hormuz2. That diplomacy belongs to another desk; what matters for the gas book is the price signal.
The ban itself left no measurable upward mark. The long-term TurkStream exemption to September 2027 and six origin waivers mean the enforceable near-term volume is small, so the market had read the regulation as procedural well before binding day. The result inverts the level that defined late May: a US-Iran headline knocked 8.1% off the benchmark on 26 May and confirmed €50 as a diplomatic-premium ceiling, and that same premium has now collapsed, with the benchmark trading roughly 50% above pre-war levels on physical balance alone3.
