US natgas prices gain nearly 3% on mid-July heat forecasts, more cooling demand

U.S. natural gas futures for August delivery rose 2.8% to $3.51/MMBtu on Wednesday, breaking a two-day decline, primarily driven by hotter mid-July weather forecasts anticipating increased air-conditioning demand and higher gas burn by power generators. This upward movement is further supported by LNG export terminals completing maintenance, signaling increased export capacity. While domestic gas output slightly eased, overall demand, including exports, has risen, with market participants now closely watching Thursday's EIA storage report for potential impact on winter contracts, amid ongoing uncertainties regarding summer heat and tropical storm activity.

Analysis

U.S. natural gas futures for August delivery rebounded 2.8% to $3.51 per million British thermal units, reversing two prior days of declines. The primary catalyst for this upward movement is a shift in weather forecasts, which now project hotter-than-normal temperatures for mid-July. LSEG data quantifies this with a forecast of 206 total degree days (TDDs) over the next two weeks, a significant increase from the previous day's estimate of 182 and well above the seasonal norm of 172, signaling elevated demand from gas-fired power plants. This demand-side pressure is complemented by expectations of a recovery in LNG export volumes as terminals complete maintenance, which analysts see as a source of fundamental support. On the supply side, a minor easing in Lower 48 gas output to 106.2 billion cubic feet per day (bcfd) in July provides an additional tailwind. However, current storage levels at 2,949 bcf are 6.1% above the five-year average, which may temper upside potential. The market's immediate focus is on the upcoming EIA storage report, where an injection below the consensus of +51 bcf could further tighten the outlook and push winter contracts toward the $5 level. Risks remain, particularly from hurricane season, which BofA Global Research notes could be bearish for domestic prices if LNG export infrastructure is disrupted.

Key Decisions for Investors

• Monitor Thursday's EIA storage report closely; an inventory build significantly below the +51 bcf forecast would validate the bullish sentiment driven by heat and could signal further near-term price strength.
• Investors with long domestic natural gas positions should be aware of the two-sided risk from hurricane activity, as disruptions to LNG export terminals could be bearish for Henry Hub prices even if bullish for global benchmarks.
• While near-term catalysts are bullish, weigh this against current storage levels, which are 6.1% above the five-year average and could cap the extent of a price rally without sustained, extreme heat or supply disruptions.
• Consider the tightening global supply backdrop, evidenced by a 4.4% drop in Russian LNG exports, as a long-term structural support for U.S. LNG export demand and domestic prices.
