A wild spike in expiring natural-gas futures contracts on Thursday afternoon was the latest bout of extraordinary volatility that has whipsawed financial markets to start the year.
Natural-gas futures for February delivery settled 46% higher, at $6.256 per million British thermal units, the largest one-day gain on record. More heavily traded futures for March delivery ended the day up 8.1% at $4.363.
Futures for more distant deliveries moved similarly to March contracts in a rise that isn’t unusual for this time of year, when traders wager on the severity of winter weather and the demand it will create for the heating and electricity-generation fuel.
Forecasts monitored by traders on Thursday were revised lower for early February, signaling greater demand beyond the storm that is expected to freeze much of the country this weekend.
At one point, late in the trading session, February futures jumped to nearly $7.35 before crashing back down and rising again to the closing price. Moves throughout the day were so sharp that trading was paused a dozen times by circuit breakers aimed at maintaining orderly trading, exchange operator CME Group Inc. said in a statement.

“This market worked as designed,” CME said.
The timing and sharpness of the February futures’ spike—and the relatively small number of trades involved—suggests speculators trapped in wrong-way bets on the direction of fuel prices raced to buy futures at the 11th hour to settle trades. Known as a short squeeze, the situation can produce sharp gains with little connection to market fundamentals.
In a note to clients, Ritterbusch & Associates said that speculators clawing out of short positions “accentuated what would normally be a modest price hike.” The oil-and-gas trading firm told clients that it believed prices would fall as winter passed without significant declines in domestic stockpiles and advised them against piling into Thursday’s rally.
The U.S. Energy Information Administration said Thursday that gas stockpiles ended last week nearly 11% lower than last year, though just 1% short of the five-year average inventories.
