Forwards Down 2%, Day-Ahead Volatile: October's Real Story
October proved a critical lesson: forwards are rational, day-ahead is noise. Geopolitical shocks spiked spot prices 35% in a single day, but forwards traders ignored them. By month-end, structural forces won: LNG supply, mild weather, and Norwegian production pushed prices lower. For your renewals, what matters is forward pricing, not spot noise.
① The Month at a Glance
🎯 The Real Story
October saw forwards fall consistently (Cal-26 gas -2.03%, power -1.43%), but this masked wild day-ahead volatility. Mid-month geopolitical shocks (Gaza escalation, Russia sanctions) spiked day-ahead prices significantly mid-week, but forwards traders didn't believe it would be structural. By month-end, day-ahead crashed as supply improved and weather forecasts turned milder. Forwards stayed rational throughout—this is what your supplier uses to quote you.
📌 Critical Distinction: Your renewal quote is based on forward contracts(Cal-26, Q1-26), NOT day-ahead spot prices. When you see "spot prices crashed 35% in one day," that's noise. Your actual price is determined by the forward market, which moved only -2% for the month. This is why forwards matter more than headlines.
Monthly Forward Performance
⚠️ Key Observation: Winter power (Q1-26) went UP (+1.49%) while full-year power (Cal-26) went down. This is healthy and normal —traders are pricing seasonal demand correctly. Winter heating and lighting drive higher power prices. The fact that Q1-26 only rose 1.49% suggests no shortage fears; supply is stable enough that winter premium is modest.
② Month Trend Analysis: Where Prices Moved
The Weekly Pattern
October followed a clear pattern: early stability, mid-month volatility, late-month structural break lower. Here's what happened:
| Week | Period | Cal-26 Gas | Cal-26 Power | Story |
|---|---|---|---|---|
| Week 1 | 01-03 Oct | 80.23 → 80.01 | 76.72 → 76.64 | Stable open. Mild weather, no demand signal |
| Week 2 | 06-10 Oct | 79.77 → 80.95 | 76.92 → 77.11 | UP mid-week- heating season starting to price in |
| Week 3 | 13-17 Oct | 80.35 → 79.70 | 76.84 → 76.98 | PEAK on 13th- geopolitical risk premium, but fading |
| Week 4 | 20-24 Oct | 78.74 → 80.50 | 76.42 → 76.75 | Consolidation. Day-ahead volatile, forwards stable |
| Week 5 | 27-31 Oct | 79.80 → 78.60 | 76.07 → 75.62 | BREAK LOWER- supply improves, weather turns mild |
What Drove Each Week
📘 Week 1: Baseline (1-3 Oct)
Stable open to October. Forwards pricing in mild weather forecasts and normal autumn transition. No supply shocks. LNG steady. This was the "default" market—prices flatlined.
📙 Week 2: Demand Signal (6-10 Oct)
Forwards UP on 10th. Market starting to price heating season. Temperature forecasts showing drop from mild to normal-seasonal. This is when traders first bid winter contracts, creating the seasonal premium lift.
📕 Week 3: Geopolitical Peak (13-17 Oct)
13th Oct: Peak of the month for Cal-26 Gas (80.35). Israeli strikes and Russia sanctions announced. Day-ahead crashed, but forwards peaked this week. Geopolitical risk premium visible. However, note that forwards then fell for the rest of the week—traders quickly decided this wasn't structural.
📙 Week 4: Consolidation (20-24 Oct)
Forwards oscillated. Day-ahead had volatility, but forwards barely moved. This confirms the pattern: day-ahead noise ≠ forward repricing.
📗 Week 5: Break Lower (27-31 Oct)
Finally, forwards broke lower. Norwegian supply ramping. LNG steady. Weather turning mild again. Geopolitical premium fading. Structural downside from supply and weak demand.
③ October 2025 vs October 2024: The Shift
October 2024 was elevated due to energy crisis residue. October 2025 is a surplus market. The difference is structural, not cyclical.
Day-Ahead Spot Price Comparison
The Interpretation
- Last year (2024): Energy crisis lingering. Prices high, but day-to-day swings were smaller. Supply uncertainty created consistent premium.
- This year (2025): Supply abundant (LNG, Norwegian production), prices lower overall, but day-to-day volatility is higher. Geopolitical events move spot prices sharply. However, forwards tell the true story: -2% for the month.
- What this means: Lower average prices are good news. Higher spot volatility is manageable because you renew on forwards, not spot. Your supplier hedges the volatility—you lock in a stable forward rate.
💡 For Your November Renewals: Prices are structurally 15-20% cheaper than last year. But volatility means day-to-day spot can swing 20-30%. This is why you renew on forwards, not spot. Your supplier will quote you based on Cal-26 (78.60) + their margin. Don't get distracted by spot noise; focus on forward levels and lock in when they're fair.
④ November Outlook: What to Watch
The November Signal
Nov-25 contracts ended October at 77.77 p/th (gas), down from opening around 80.55. This shows steeper downside than Cal-26 (which fell 2.03%). The market is saying: November will be cheaper than the full-year average. Why? Autumn is milder season, and supply ramping.
Key Drivers to Monitor in November
🟢 Downside Pressure (Expect Lower Prices)
Norwegian Supply:
Maintenance wrapping up. Troll, Sleipner, Langeled ramping. Structural supply relief through November.
LNG Arrivals:
Multiple cargoes/week. Competition strong. If sustained, drives downside on storage fills.
Mild Weather Risk:
If forecasts hold 2-3°C above normal, heating suppressed. Biggest downside catalyst.
🔴 Upside Risk (Watch for Rallies)
Geopolitical Tail Risk:
Gaza, Russia, Middle East escalation could spike day-ahead quickly. October proved DA can move 35% in one day on geopolitical news. Stay alert but remember: forwards won't panic as much.
Weather Surprise:
Early cold snap (colder than forecast). Power would react faster than gas.
Supply Disruption:
Major outage at Norwegian field or LNG terminal.
November Renewal Strategy
- 0-3 months to renewal: Lock in now or within 1 week. Nov forwards suggest slight downside, but you're close to expiry. Cal-26 at 78.60 is fair and you need certainty.
- 3-6 months to renewal: Wait and watch, but set price alerts. If Nov-25 breaks below 76 p/th, move within 48 hours—that signals structural break.
- 6+ months to renewal: You're in the sweet spot. Summer 2026 (Sum-26) is genuinely cheap. Wait for summer pricing window (May-June 2026).
⑤ Renewal Guidance: Your Next Steps
🎯 Executive Summary: October proved forwards are reliable. Your supplier quotes based on Cal-26 (78.60 gas, 75.62 power) + margin + costs. Use these as your baseline. If quotes are 2-4p/th higher, that's normal margin. If they're 8-10p/th higher, ask why—either the supplier is being greedy or the market has moved since your quote request.
0-3 Months to Renewal
ACTION: Lock In Within 1 Week
You need to renew soon. Cal-26 at 78.60 is genuinely low compared to Oct 2024 (99). Lock in now and stop gambling. Even if November prices drift to 76, you're only 3% worse—acceptable cost of certainty.
Why: If geopolitical risk flares and forwards spike to 85-90, you'll regret waiting.
3-6 Months to Renewal
ACTION: Set Alerts & Wait
You have breathing room. Use October's lesson: forwards don't panic to day-ahead shocks. Set price triggers and wait.
Alerts:
• Gas Cal-26 breaks below 77 p/th
• Power Cal-26 breaks below 74 £/MWh
→ Move within 48 hours when triggered
6+ Months to Renewal
ACTION: Plan Summer Lock-In
You're in the sweet spot. Summer 2026 is seasonal cheap—lower than full-year average. If you can wait, lock summer rates May-June 2026, handle winter separately later.
Strategy: Monitor Cal-26 through November-December. If it breaks below 76 structurally, consider locking some winter volume then. Then wait for summer.
Understanding Your Quote vs Market Data
📌 Important Clarity:
When you see "Cal-26 Gas 78.60 p/th," that's the wholesale forward price. Your actual business quote will be higher because your supplier adds:
• Margin:
Typically 2-4p/th for mid-market customers
• Costs:
Imbalance charges, transmission, hedging costs
• Risk premium:
If market is volatile, supplier adds 1-2p/th
So if Cal-26 is 78.60, expect a retail quote of 82-86p/th
depending on your size and credit. This is normal. Don't compare wholesale to retail—apples and oranges.
October Proved a Critical Lesson
Day-ahead prices crashed and spiked wildly, but forwards held disciplined. The market knows what matters: supply fundamentals, demand patterns, and seasonality. Geopolitical shocks are temporary. Lock in your renewals based on fair forward pricing—not spot noise.
