September 6 Natural Gas Storage Report: Weather Turned Bearish Over The Weekend

by: Bluegold Research

This Thursday, we expect EIA to report 2,573 bcf of working gas in storage for the week ending August 31.

We anticipate to see an injection of 68 bcf, which is 8 bcf larger than a year ago and 3 bcf larger vs. 5-year average.

Weather forecast turned bearish over the weekend, but there were also other reasons to short natural gas.

Latest trading results are in the report (scroll down).

The Weather

Last week, the number of total degree-days (TDDs) increased by almost 16% w-o-w, as cooling demand went up – particularly, in the Northeast and Southeast parts of the country. We estimate that total energy demand was no less than 35% above last year’s level. Please note that during this time of the year, heating degree-days (HDDs) have almost no effect on natural gas consumption. Cooling degree-days (CDDs) continue to have a disproportionately stronger effect on consumption, and traders should be paying attention to changes in CDDs. Seasonal trend, however, calls for high but declining number of CDDs and for a rising but low number of HDDs.

This week, the weather conditions cooled down. We estimate that the number of CDDs will drop by 7.0% w-o-w in the week ending September 7. However, total energy demand (measured in TDDs) would still be some 20% above last year’s level. Next week, weather conditions will cool down even more. The number of CDDs is currently projected to drop by no less than 20% w-o-w for the week ending September 14 (see the chart below).

The latest numerical weather prediction models are still showing above normal CDDs and TDDs over the next 5 days (September 5 – 20), but the changes have been very bearish lately. As you can see from the tables below, the weather models first showed sharp bearish changes on Sunday, September 2. Then, more bearish changes appeared on Monday and Tuesday.

Today’s 06z weather models project an average of 9.8 CDDs per day (1.8 above the norm) over the next 15 days (September 5 - September 20), but the change from Tuesday is bearish (24h change is -0.6 in 06z run). Currently, there are no major disagreements between the models. HDDs also impact consumption - especially in residential and commercial sectors, but during September-October, the number of HDDs should remain relatively low. The latest 06z run projects an average of 0.7 HDDs per day over the next 15 days (0.7 below the norm), and the change from Tuesday is bullish, yet minor (24h change is +0.2 in 06z run).


U.S. Energy Information Administration should report a slightly smaller change in natural gas storage this week compared to the week prior. We anticipate to see an injection of 68 bcf (3 bcf larger than the comparable figure in the ICE’s latest report for the EII-U.S. EIA Financial Weekly Index, 3 bcf larger vs. 5-year average and 8 bcf larger than a year ago).

There is currently a double deficit in natural gas inventories – i.e., the amount of natural gas in the underground storage is smaller compared to previous year and also compared to 5-year average. Next two EIA reports are expected to confirm the contraction of 5-year average deficit by a total of 6 bcf and the expansion of annual deficit by a total of 2 bcf.

Further down the road, however, we see larger injections both relative to 5-year average also compared to last year.

Trading Results

Our subscribers know that we started to lean bearish on natural gas from around August 7. We have been building our short positions for several weeks, but most recently, we began reducing our short exposure and rip profits. Below is the list of the most recent 10 trades (click here to see the full list).

Returns are "unleveraged". If you trade ETNs, equivalent returns would have been 2 or 3 times greater.

We maintain our bearish bias on natural gas, but a technical rebound from 2.814-2.806 is possible - probably towards 2.831 and maybe towards 2.846 and 2.853. We might open a minor long position (simply to hedge our existing short exposure), but we are not recommending going outright long right now. Overall, we will be looking for opportunities to sell the rallies.
