📉 Interpreting the Chart: Key Market Movements

Key Patterns:


  • 📈 Mid-June Gas Spike: Prices surged following Israeli strikes on Iran’s infrastructure, raising fears over LNG disruption via the Strait of Hormuz.


  • ⚠️ Electricity Volatility: Record lows hit on 23rd & 24th June due to weak demand and strong wind, skewing the monthly average.


  • 💡 Late June Softening: Ceasefire announcements and resumed Norwegian flows eased prices lower to close the month.

📊 Price Comparison Table

Commodity June 2025 Avg May 2025 Avg Change
Gas (p/therm) 86.61 82.60 ⬆️ +4.9%
Power (£/MWh) 71.43 77.78 ⬇️ -8.15%

🌍 What Drove the Market?


🔥 Geopolitics:


  • Mid-June saw Israeli strikes on Iranian nuclear sites and a brief oil price surge as the U.S. signalled possible intervention.
  • A ceasefire was later announced, but markets remained cautious, especially around LNG flows through the Strait of Hormuz.


☀️ Weather & Renewables:


  • June was hotter than average, increasing cooling demand but failing to significantly lift prices.
  • Strong wind output (especially late June) suppressed power prices — leading to record lows on 23rd & 24th June.


🏭 Supply & Storage:



  • Norwegian maintenance disrupted gas flows early in the month but resumed by month-end.
  • EU storage continued filling steadily, sitting near seasonal norms.

Summary:


  • 🧊 Winter 24–25 Prices Dropped: Good for early fixers
  • 📈 Gas prices briefly spiked mid-June on conflict risk
  • ⚠️ Power volatility remains high — timing is critical for power fixers

💡 What This Means for Your Business

  • 📅 If your contract ends by August

    Now’s your chance. Forward prices for Autumn 2025 are down ~20% compared to June’s highs. Lock in early and avoid the next spike.

  • 📆 If you're fixed until 2026 or 2027

    It’s worth comparing prices anyway. Winter 2026 has dropped 7–9% this month — consider re-tendering early if you use significant volume.

  • 🧾 For multi-site or heavy energy users

    Electricity volatility makes comparisons harder — send us your data and we’ll map the most stable contract windows.
