US natural gas futures rallied 7.4% on Monday, December 29, as the January Nymex contract rolled off the board at $4.687/MMBtu, a three-week high. The February contract, which became front-month, gained 2.8% to $3.986.
Colder weather in the North and West and record or near-record LNG feedgas deliveries were cited as the main drivers.
Colder heating demand and strong LNG pull tighten US gas balances, supporting prices and raising the cost of natural gas-based feed inputs such as DDGS and fuel for drying and processing.
After 221 past bullish weather events, Natural Gas moved a median +3.3% over 5 sessions (61% higher; middle half -5.2% to +14.0%), and -0.3% over 20.
