据油价网7月21日报道，美国标准的天然气价格7月21日早些时候出现下跌，但由于夏季气温飙升，以及最新报告周期内天然气储存增量小于预期，天然气价格将实现四周以来的首次周涨幅。

到美东时间上午9时35分，最近期的亨利枢纽中心合约交易价格下跌1.49%，至每百万英热单位2.715美元。

EIA周四发布的《每周天然气储存报告》显示，7月14日当周，储存天然气净增加410亿立方英尺。与2018至2022年五年均值的45亿立方英尺净注入数据相比，储存增量较小，也低于分析师预期的储存增量44亿立方英尺。

较小的储气增量和炎热天气预测使得天然气期货价格在当地时间7月20日上涨6%。虽然价格在7月21日早些时候有所回落，但仍将实现7%至8%左右的周涨幅，这将是自6月中旬以来的最大周涨幅。

根据大型咨询机构全球商品洞察提供的数据，上周美国总的天然气消费量较上一周增长了5.4%。特别是得益于得克萨斯州、西南部和加利福尼亚地区的高温天气，用于发电的天然气消费量周环比上涨了8.5%。得克萨斯州的用电需求在本周热浪中创下了新高。

气象预报显示，美国天然气需求至少在7月26日之前将保持较高水平。

U.S. Natural Gas Prices Set For First Weekly Gain In Four Weeks

The U.S. benchmark natural gas prices fell early on Friday but were set for the first weekly gain in four weeks as summer temperatures soar and injections into gas storage sites were smaller than expected in the latest reporting week.  

As of 9:35 a.m. EDT, the front-month Henry Hub contract traded down by 1.49% at $2.715 per million British thermal units (MMBtu).

Working gas in storage saw a net increase of 41 billion cubic feet (Bcf) in the week to July 14, the EIA’s Weekly Natural Gas Storage Report showed on Thursday. The net addition to inventories was lower compared with the five-year (2018–2022) average net injections of 45 Bcf and lower than the median estimate of analyst expectations of a 44 Bcf increase in inventories

The smaller gas stocks build and forecasts for hot weather sent natural gas futures jumping by 6% on Thursday. Prices turned lower early on Friday but they were still on course to post a weekly gain, of around 7-8%, which would be the biggest weekly gain since the middle of June.

Last week, total U.S. consumption of natural gas rose by 5.4% (3.9 Bcf/d) compared with the previous report week, according to data from S&P Global Commodity Insights cited by the EIA in its Natural Gas Weekly Update. Natural gas consumed for power generation jumped by 8.5% week over week with above-average temperatures in Texas, the Southwest, and California in particular. In Texas, power demand hit a record amid a heatwave this week.

Weather forecasts suggest that U.S. natural gas demand will be high at least through July 26.
