据世界石油网站10月25日报道 由于对美国东部11月寒冷天气的预测加剧了人们对今年冬天供应将难以满足需求的担忧，天然气期货价格飙升。
11月交付的亨利中心天然气价格上涨10.7%，为近三周来最大涨幅，达到5.844美元/百万英热单位。价格正在从最近的下跌中反弹，尽管仍低于本月早些时候达到的7年高点。
虽然10月温和的天气使生产商向储存库注入了比平时更多的天然气，但中西部和东部地区11月初的天气预报提醒人们，取暖和发电燃料的供应仍低于正常水平。与此同时，预计美国将出口其所能出口库存，以帮助缓解欧洲和亚洲的天然气短缺。
Again Capital创始合伙人约翰·基尔达夫表示：“人们非常担心供应是否充足，并补充称市场对任何天气转冷的预测仍然很敏感。”
供应担忧加剧的一个迹象是：价差在3月和4月期货之间扩大至1.481美元，为10月14日以来的最高水平，基本上是押注冬季结束时库存将有多紧张。
根据BloombergNEF的数据，周一流向液化天然气终端的天然气流量为113亿立方英尺，比上周五增长逾10%，为5月份以来的最高水平。在美国最大的终端之一上周面临管道中蜡堆积的问题后，德克萨斯州弗里波特液化天然气终端的估计产量已经反弹。
EBW AnalyticsGroup在给客户的一份报告中表示，交易员在11月期权合约到期前的仓位可能放大未来几天天然气价格的波动，11月期权周二到期。
美国天然气生产商的股价也大幅上涨。截至上午11:51，EQT公司上涨5.2%，Antero资源公司上涨5.6%。

U.S. natural gas prices soar 10% as cold winter forecasts develop
Natural gas futures soared as forecasts for chilly November weather in the U.S. East heightened concern that supplies will struggle to meet demand this winter.
Henry Hub gas for November delivery gained as much as 10.7%, the biggest gain in almost three weeks, to $5.844 per million British thermal units. Prices are bouncing back from recent declines, though they’re still shy of the seven-year high reached earlier this month.
While mild October weather allowed producers to inject more gas into storage than usual, forecasts for a cooler early November in the Midwest and East are a reminder that supplies of the heating and power-generation fuel are still below normal. Meanwhile, the U.S. is expected to export every molecule it can to help ease shortages of gas in Europe and Asia.
“There is terrific concern about sufficiency of supply”, said John Kilduff, founding partner at Again Capital, adding that the market remains sensitive to any cold forecasts.
One sign of growing supply fears: The so-called widowmaker spread between March and April futures, essentially a bet align="justify"> Flows to liquefied natural gas terminals are seen at 11.3 billion cubic feet align="justify"> Traders positioning for the expiration of November options contracts could amplify volatility in gas prices in the next few days, EBW AnalyticsGroup said in a note to clients.
