Comparative Inventory and Natural Gas Storage Report June 8, 2020 (2020-1)

Highlights of this week’s report:

  • Natural gas surplus greatest in 2.5 years.
  • Storage levels are higher than any previous year except for 2016.
  • Henry Hub correctly priced at $1.76/mmBtu.
  • Production is lower but so is consumption.
  • Cool weather has not helped prices but that is changing.

Comparative Inventory and Storage

Many analysts and investors believe that lower associated gas production should lead to higher natural gas prices. The data does not support that view so far.

Natural gas comparative inventory (C.I.) has been increasing since March 2019 and has been higher than the 5-year average throughout 2020 (Figure 1). The negative correlation between C.I. and gas price is strong so it is not surprising that gas prices have fallen since the maximum negative C.I. more than a year ago. For more on comparative inventory, please see this and other posts on my website.

This means that gas markets are more over-supplied than they have been in 2.5 years and that the over-supply is increasing for now. That is hardly a bullish signal for gas prices.

In fact, working gas in storage is at a higher level for this date than it has been since 2016 (Figure 2). Stocks increased to 303 bcf more than the 5-year average the week ending May 29 on a slightly larger-than-normal addition of 102 bcf. That is a stunning 728 bcf more than during this week a year ago. Total storage is 2.7 tcf which represents 56% of working capacity.

Cross-plotting C.I. and Henry Hub spot price results in the red yield curve in Figure 3. The C.I. – price point for the week ending May 29 (shown in yellow) plots essentially on the yield curve meaning that gas is priced correctly at $1.77.

The yield curve suggests that gas price at the 5-year average should be about $2.20/mmBtu. Yield curves change as markets perceive different levels of supply urgency but for now, it seems unlikely that winter gas prices should be very different than during the previous winter. The future strip shows the January 2021 contract price at less than $3 which is consistent with winter C.I. levels less than the 5-year average.

Supply and Demand

U.S. gas production has fallen more than 3 bcf/d from the November 2019 peak of 96 bcf/d to 93 bcf/d in April (Figure 4). It is expected to decrease another 7.7 bcc/d by December to 85 bcf/d so some see that as support for higher gas prices later in 2020.

to 93.1 bcf/d in April and is expected to fall to 87.5 bcf/d by December 2020..

The problem with that thinking is that it ignores consumption. Gas consumption decreased in the first quarter of 2020 because of the coronavirus economic closure (Figure 5). Industrial use remains depressed while other sectors have improved but have not recovered to pre-closure levels.

Consumption is expected to decrease by about 3.3 bcf/d in 2020 compared to 2019 based on EIA forecasts (Figure 6). Forecasts are always wrong but are worth our attention because they summarize current thinking based on credible modeling assumptions.

May temperatures were cooler than last year but were slightly warmer than last year for the week ending June 5 (Figure 6). If that trend continues, it will be less negative for gas prices which fell $0.06 despite demand for more space cooling. Temperatures were substantially cooler than the 10-year norm.

June through August weather forecasts indicate warmer-than-normal summer weather for the U.S. so weather may provide some upward pressure on prices in coming weeks.

Natural gas pricing for the next 6 months should be similar to the last 6 months. The economic slow-down from Coronavirus has affected gas as well as oil consumption.

Despite lower production levels, storage is well above the 5-year average and continues to increase. Over-supply is at the highest levels in more than two years.

Futures prices rallied to $2.13 in early May but then collapsed to $1.62 by mid-month (Figure 8). This was a classic example of price discovery based on sentiment that lower associated gas might result in tighter gas supply. The answer was discovered and prices have been in the $1.70-range since then as I expect they will remain for awhile.

Managed money has been short on U.S. gas since May 2019. That is clear from falling net long positions which paralleled declining futures prices from late 2018 through January 2020 (Figure 9). During the first quarter of the year, that trend reversed but peaked in May and is now moving in the opposite direction. Traders continued to unwind their long bets through the latest commitment of traders report last week.

Momentum toward a reversal of that trend appears to have peaked in early May 2020.

I am not saying that there is no possibility of a gas-price play in late 2020 and 2021. There is always considerable uncertainty about weather and the pace of economic recovery from coronavirus shutdowns. These could surprise either to the positive or to the negative for gas supply and demand. The point is that lower production of associated gas does not logically result in a supply deficit. Markets are more complex than that.
