United States Natural Gas Fund lost 88% over the past decade due to contango roll costs and price cycles.
UNG holds near-month futures and rolls them forward. Contango forces the fund to sell low and buy high repeatedly.

Natural gas just printed $30.72 per MMBtu on January 23, 2026, then collapsed to $3.13 by February 23. That is a nearly 90% round-trip in five weeks. United States Natural Gas Fund (NYSEARCA:UNG) captures every one of those moves, which is what makes it a closely watched instrument among traders tracking natural gas volatility.
The Macro Factor That Moves This Fund Most
Natural gas prices are driven by a tug-of-war between supply and demand that can shift within days. On the demand side, two forces are pulling simultaneously. Extreme cold snaps drain storage fast and send spot prices spiking, as January’s polar event demonstrated. The buildout of AI data centers is also creating durable new electricity demand, with gas-fired power plants filling that gap as grid operators struggle to keep pace.

On the supply side, storage levels matter most in the near term. When storage runs above the five-year average, prices face downward pressure even in cold weather. Warm February forecasts pushed the March Henry Hub contract toward $3 per MMBtu, with analysts warning that sub-$3 prices could be imminent without continued cold air from Western Canada. The EIA Weekly Natural Gas Storage Report, published every Thursday, is the single most important release to monitor. A storage deficit versus the five-year average is a bullish signal; a surplus points the other direction.
The Mechanic That Quietly Erodes Returns
Even if the direction of natural gas is called correctly, UNG can still underperform. The fund holds near-month NYMEX futures and rolls them forward before expiration. When the futures curve is in contango, meaning future-dated contracts cost more than near-term ones, that monthly roll costs money. The fund is effectively selling low and buying high, repeatedly. UNG has lost roughly 88% over the past decade, reflecting both price cycles and the persistent drag of rolling in contango markets. The fund carries a 1.24% expense ratio on top of that.
When futures flip into backwardation, where near-term contracts trade above longer-dated ones, the roll benefits holders. That condition typically emerges during supply crunches, exactly the environment January 2026 briefly created.
What to Watch Over the Next 12 Months
Analysts note that if EIA storage reports show consistent deficits through spring and the futures curve shifts into backwardation, UNG’s structural drag could reverse, allowing spot price gains to flow through more directly to fund performance. A normalized storage picture with a contango curve would likely mean roll costs continue to absorb a portion of any price recovery.

Wall Street is pouring billions into AI, but most investors are buying the wrong stocks. The analyst who first identified NVIDIA as a buy back in 2010 — before its 28,000% run — has just pinpointed 10 new AI companies he believes could deliver outsized returns from here. One dominates a $100 billion equipment market. Another is solving the single biggest bottleneck holding back AI data centers. A third is a pure-play on an optical networking market set to quadruple.
