U.S. natural gas prices spiked by a record 70% on Thursday, driven by low-volume trading in the expiring February contract. Most traders had already moved to other contract months, leaving thin liquidity in the final session.
The move was largely a technical expiry effect rather than a physical supply shift, so it signals volatility in Henry Hub pricing for buyers hedging feed-energy costs. Prompt-month price discovery was distorted, which can raise hedging costs for feed mills.
