NYMEX prompt natural gas hit a two-month high after a force majeure on Columbia Gas's Mountaineer XPress pipeline cut Appalachian output by more than 2.2 Bcf per day. No return-to-service timeline was announced for the affected segment.
A lasting pipeline outage removes regional supply from the market and supports Henry Hub prices. The effect on feed costs runs through higher gas-fired power and fertilizer costs.
After 54 past bullish logistics events, Natural Gas moved a median -1.8% over 5 sessions (43% higher; middle half -5.7% to +6.2%), and +5.1% over 20.
