The Natural-Gas Glut Has Evaporated, Driving Prices Higher

Natural-gas futures ended Friday at $3.215 per million British thermal units, up 96% from a year ago and the highest price headed into summer since 2017. Futures traded even higher—and regional spot prices jumped—when triple-digit temperatures baked the Southwest earlier this month. Analysts expect prices to be even higher later in the year when it is time to fire up furnaces.

It isn’t just in the U.S. where gas is running high. Dutch gas futures, a barometer for prices in Western Europe, have more than doubled over the past year—including a sharp rise since February—to multiyear highs. In Asia, imported liquefied natural gas is fetching more than five times what it did last June, beckoning tankers full of chilled shale gas across the Pacific.

More expensive gas has stoked demand in international markets for coal, with which gas competes to fuel power plants. Futures prices for thermal coal loaded at a terminal in Newcastle, Australia, have more than doubled from a year ago. The benchmark price has added 27% over the past month and hasn’t been so high in nearly a decade.

If higher prices persist, Americans can expect bigger utility bills. The work-from-home class could feel a pinch. The pandemic shifted energy costs from employers to employees, who have heated and cooled home offices and run electronics when they would normally be away at work. 

Besides being burned to generate electricity and for hot showers and cooking, natural gas is consumed in large volumes to make plastic, fertilizer, steel and cement. Monetary-policy makers don’t consider energy prices when gauging inflation because they are so volatile. Yet climbing gas prices are adding to the costs of producing manufactured goods at a time when investors are on edge about the potential for runaway inflation.

“These are the consequences of the underinvestment we’ve seen in natural gas,” said Colin Fenton, chairman of investment banking at Houston’s Tudor, Pickering, Holt & Co. “What’s notable is these prices are happening with industrial demand, more than a quarter of the market, so early in its recovery.”

U.S. natural-gas output peaked in December 2019. March marked the 11th straight month in which production in the contiguous 48 states declined, according to the U.S. Energy Information Administration. There are only five more rigs drilling for gas now than the 92 operating at the end of March, according to oil-field service firm

Baker Hughes Co.

Appalachian energy producers, which control the country’s gas spigots, have taken a cautious approach to reopening the wells they shut last spring when the pandemic sank prices. Drillers in the Haynesville shale that straddles Texas and Louisiana have been slow to tap their reserve of wells that have been drilled but not yet fracked to start them flowing. 

Gas producers had suffered for years from low prices caused by their own market-glutting gushers. Shareholders and analysts pressured producers to focus less on growing volume and more on profitability. 

The reward has been climbing stock prices. Shares of gas producers

Range Resources Corp.

and

Antero Resources Corp.

have been some of the best performers in the rebounding energy sector, both up more than 40% over the past three months. 

A mild start to winter threatened to leave the country’s gas-storage caverns filled to capacity until February, when Texas froze over. Demand for heat shot up at the same time that many ice-choked wells stopped flowing. 

Overseas buyers are clamoring for shale gas to restock depleted inventories after canceling cargoes a year ago. Demand from Mexico has increased with the opening of a new pipeline system south of the border. Drought has reduced hydropower in the western U.S., and it is being made up for with more gas to cool homes and businesses during the heat wave that last week pushed temperatures above 100 degrees in Phoenix, Las Vegas and Los Angeles.

All the demand has meant smaller injections into U.S. stockpiles, which are built up during the spring and summer ahead of winter, when demand usually outstrips production. U.S. gas inventories, which brimmed near all-time highs in November, are now 16% below last year’s levels and 4.9% less than the five-year average for this time of year.

“In the past we’ve had these demand gains, but they were all overwhelmed by production increases,” said Kent Bayazitoglu, who tracks gas supplies for Baker & O’Brien Inc., an energy consulting firm. “We don’t have that any more.”
