There was hope that the new Matterhorn pipeline from Waha to the Katy/Houston area would be a reprieve for negative natural gas prices in West Texas.  After the pipe started flows in October 2024 it took a while, but by Mid November according to NGI, Waha prices were up to average $2.50/MMbtu through February.  

But in the first week of March, Waha gas prices were again falling like a rock to 70 c/MMbtu in the first week of the month, 30 c/MMbtu in the second week. Then in last Friday’s trading, Waha crashed to negative 84 c/MMbtu, the first negative Waha price recorded in 2025 (purple dashed oval on left graph).   Basis nosedived to negative $4.76/MMbtu (red dashed oval on right graph).    

Marketers gave several reasons for the collapse, mostly blaming pipeline maintenance on El Paso and Whistler. No doubt maintenance was part of the problem, but production looks to be growing faster than expected, now up to 20.6 Bcf/d, putting more downward pressure on Waha sooner.
