Contracts Roll, Near-Term Turns Negative — The Conflict Premium Unwinds

The week the reference contract changed. April expired. May took front month. Sum-26 replaced by Sum-27. Gas fell 6% twice — despite Trump warning he'd hit Iran "extremely hard." Weather beat geopolitics. Near-term contracts turned negative over 30 days for the first time since the conflict began. The curve is normalising fast.

The week's story

What Happened

This was the week everything shifted. Not because of a headline — because of a calendar. April expired on Tuesday. May took front month at 128p. The seasonal reference rolled from Sum-26 to Sum-27. And the new reference immediately fell: down 6.1% on Wednesday on contract rollover pressure and reports of possible US-Iran diplomatic talks, then down another 5.7% on Thursday despite Trump warning he'd hit Iran "extremely hard."

The market's message was clear: weather beats geopolitics. North West Europe saw temperatures 5°C above seasonal averages. Wind generation strengthened. Heating demand collapsed. Traders closed positions ahead of Easter. None of that cared about Trump's rhetoric.

The most significant development wasn't the daily moves — it was what happened to the 30-day picture. Near-term contracts turned negative over 30 days for the first time since the conflict began. May-26 gas down 11%. May-26 power down 13%. Jun-26 gas down 7%. The conflict premium hasn't just stopped growing — it's been given back entirely at the front of the curve.

Further out, the picture is different. Sum-27 still up 23% over 30 days. Win-27 gas up 28%. Q4-26 up 5%. The structural damage (Ras Laffan, Hormuz, storage at 28%) is still priced into the longer-dated contracts. But the near-term normalisation is happening faster than anyone expected.

Price drivers

What Moved the Market

📉
Contract rollover — April expires, May front month — the single biggest factor this week. The switch from April to May pricing, and the seasonal reference shift from Sum-26 to Sum-27, accounted for the bulk of Wednesday's 6% drop.
📉
Warm weather across NW Europe — temperatures 5°C above seasonal averages by Thursday. Slashing heating demand. The warm spell was the main reason the market ignored Trump's escalation.
📉
US-Iran diplomatic signals — reports overnight Tuesday suggested talks may begin. Unconfirmed but the market took some geopolitical premium out. First real diplomatic signal since the conflict began.
📉
Stronger wind + Easter positioning — wind output increasing across Europe. Traders closing positions ahead of the long weekend. Thin liquidity amplified the sell-off on Thursday.
📈
Trump escalated Iran rhetoric — warned he'd hit Iran "extremely hard" on Thursday. Demanded allies help secure Hormuz. The market shrugged it off — but the threat hasn't gone away.
📈
Storage refill challenge unchanged — Europe at 28%, target 80% by November. Ras Laffan 17% offline. Hormuz constrained. Norwegian maintenance ahead. The structural picture hasn't changed — just the near-term pricing of it.

When Should I Renew?

Based on where the week closed and the 30-day trend.

Summer Renewals
Contract ending Apr–Sep
🔥 Gas: WORTH WATCHING ⚡ Elec: WORTH WATCHING

Both fuels negative on the week and the sell-off accelerating. Near-term May-26 now negative over 30 days for both fuels. Sum-27 still up 23% gas and 7% power — but the direction is firmly lower. A decent window to get quotes as a benchmark. Structural risks (storage, Ras Laffan) haven't changed but the market has stopped paying a daily premium for them.

Winter Renewals
Contract ending Oct–Mar
🔥 Gas: PRICES RISING ⚡ Elec: WORTH WATCHING

Win-27 gas still up 29% in 30 days despite this week's 6.6% fall. Power is a new contract — no 30-day history. Winter is most sensitive to the storage refill challenge (28% → 80%). Gas-heavy businesses should have a benchmark quote ready. Power can watch.

If your contract doesn't end until 2027 or beyond, you have time — and the curve is working in your favour. Cal-27 gas at 97.99p is already 22% below current near-term rates (May-26 at 120p). Cal-28 at 73.17p is 39% below. The market expects prices to normalise as infrastructure is rebuilt and supply recovers — but it still has a significant conflict premium baked in (Cal-27 up 22% in 30 days). No rush to act. Follow the market and look for a clearer signal that the premium is easing further.

💡 Tip: Gas and electricity don't always move together. If your business uses mostly one fuel, focus on that signal. We're always happy to talk through your specific situation.
Looking ahead

What to Watch

Markets are closed Friday–Monday for Easter. When they reopen Tuesday, the big question is whether the sell-off resumes or the diplomatic/geopolitical picture changes the direction. Warm weather should persist into early next week (5°C above average) before turning cooler into mid-April. Wind strengthening. Norwegian maintenance ahead but minor.

The structural picture hasn't changed: storage at 28% vs the 80% target, Ras Laffan 17% offline for years, Hormuz still closed. Trump's rhetoric is escalating, not de-escalating. But the market has shown this week that near-term fundamentals (weather, wind, positioning) can override the geopolitical noise. Follow our daily market reports for the latest when trading resumes.
