| Eia Storage Report | Weekly Natural Gas Storage Report • Energy Information Administration (EIA) • Every Thursday at 10:30 AM Eastern Time • www.eia.gov/naturalgas/storage/ • Weekly change in US natural gas storage levels • Billion cubic feet (Bcf) • Primary weekly catalyst for NG prices |
| Report Terminology | Gas added to storage (typically Apr-Oct) • Gas removed from storage (typically Nov-Mar) • Same as injection - Storage increased • Same as withdrawal - Storage decreased |
| Tax Treatment | Section 1256: 60% long-term, 40% short-term • Ordinary income (held < 1 year) • Long-term capital gains (held > 1 year) |
Reuters and Bloomberg surveys are the standard sources, typically published Tuesday or Wednesday before the Thursday report. Many financial news sites, trading platforms, and broker economic calendars also show the consensus estimate. Always know this number before the report.
No - the market already knows if it will be a draw (winter) or build (summer) based on the season. What matters is whether the actual number is different from EXPECTED. A draw that's smaller than expected is actually bearish, even though it's a draw.
The 10:30-10:45 period is extremely chaotic with algorithm-driven spikes, wide spreads, and potential whipsaws. Slippage can be severe. Professional traders wait for the settle (10:45+) to get better entries. Missing the first 15 minutes is worth the safer entry.
If the actual number is very close to expected (within 3-5 Bcf), there's typically no clear trade. The reaction may be choppy or muted. In this case, it's usually best to skip trading this particular report and wait for next Thursday.
For intraday trades, consider exiting by end of day if direction is unclear. If the move has momentum, you can hold for swing (days). Key is to have a plan: target, stop, and time-based exit. Don't hold indefinitely hoping it will work.
If storage is well below 5-year average, bullish surprises tend to produce larger moves (amplified reaction) - you might use normal size. If storage is well above average, bullish surprises may produce smaller moves (muted reaction) - consider smaller size. Adjust based on context.
Pre-positioning requires high conviction from analysis (weather, production, consensus gaps). It's binary - you can lose immediately if wrong. If you do pre-position: Use small size, know your exit price if wrong, and consider using options for defined risk. Most traders are better served trading post-report.
Before report: Check last week's weather (reported period). Storage should reflect that weather's impact. After report: If storage matches weather expectation, report confirms. If storage doesn't match (cold week but small draw), that's significant - indicates other factors at play. Also consider upcoming weather for hold duration.
Momentum trade: Clear surprise (5+ Bcf), initial move matches surprise magnitude, trade in direction of surprise. Fade: Small surprise (<5 Bcf) but disproportionately large initial move (overreaction), fade after 11:00 AM when spike exhausts. Fading is riskier and requires quicker judgment.
Instead of trading each report in isolation, you trade the cumulative storage trend. If storage is persistently below 5-year average and deficit is widening, that's a bullish theme. Use each supportive report to add to your position. Exit when the theme reverses (deficit narrows, surplus builds).
Combine: 1) Weather impact (HDDs/CDDs for reported week × historical multiplier), 2) Production data (any changes from prior week), 3) Exports (LNG volumes, Mexico pipelines), 4) Imports (Canada), 5) Known demand factors. Track your estimates vs actuals over time. Only useful if you consistently beat consensus.
Straddle (ATM call + put): When expecting big move, uncertain of direction. Strangle (OTM call + put): Cheaper but needs bigger move. Directional (calls or puts): When you have conviction. Consider IV: It rises into the event, so early-week entry may be better. Exit after move to avoid IV crush and time decay.
Front month is more reactive to weekly data than deferred months. If expecting bullish surprise, you can long front/short back (spread widens if front spikes more). Lower risk than outright but also lower reward. Spread may continue adjusting for days after report.
Yes, but challenging. You need: Real-time data feed for actual number, surprise calculation logic, wait timer (10:45+) or volatility measure, entry/exit logic with risk management. Backtesting limited (~52 reports/year). Semi-automated (algo signals, human approves) often optimal. Full automation requires robust error handling.
Monday-Tuesday: Analyze weather for reported week, check production. Wednesday: Get consensus, compare to your analysis, finalize plan, maybe pre-position. Thursday pre-10:30: Final prep, have levels ready. 10:30: Note surprise immediately. 10:45+: Execute plan. Post-report: Manage position, record results, learn for next week.
