Break-even production costs for most US producers range from $2.50-$4.00/MMBtu, so sustained prices below $2 force producers to curtail output, reduce capital spending, or declare bankruptcy. This creates short-term oversupply pressure but eventually tightens supply through well shut-ins.

Historical Context

Natural gas has traded between $1.50 and $14/MMBtu over the past 20 years. Major collapses: 2012 (shale oversupply, $1.90), 2015-2016 ($1.60), and 2024 ($1.60 amid warm winter and oversupply).
