Natural gas futures ETF UNG underperforms as contango roll costs and weak spot prices erode returns despite rising LNG exports.
The United States Natural Gas Fund (NYSEARCA:UNG) has declined 77.14% over five years, closing at $11.60 on July 7, 2026, despite a surge in LNG demand. The fund’s structure, which rolls front-month futures, incurs contango roll decay, compounding losses alongside a 1.24% expense ratio.
LNG exports are projected to reach 27.7 Bcf/d by 2030, benefiting producers rather than futures-based ETFs. Henry Hub spot gas traded at $3.33 per MMBtu on June 29, 2026, unchanged from a year earlier, while UNG fell 22.17% over the same period. Competing ETFs holding gas producers have outperformed, returning 99% on the same demand thesis.
UNG’s assets total $447.76 million, with 42.79% allocated to natural gas futures. The fund’s underperformance highlights the structural disadvantages of futures-based commodity ETFs in sideways or declining spot markets.
