A bearish surprise in government storage data put a damper on the natural gas futures market on Thursday, halting a four-day streak of gains for the prompt month. The U.S. Energy Information Administration reported an 85 billion cubic feet (Bcf) build in storage, which was slightly higher than expected, leading to a shift in market sentiment.
The build came despite the fact that offshore operators in the Gulf of Mexico had shut in 1.13 billion cubic feet per day (Bcf/d) of natural gas production due to the impact of Hurricane Isaias. This shut-in volume highlighted the potential for supply disruptions in the region, which had previously been a source of bullish sentiment.
Analysts had been forecasting a smaller build, with some models shedding heating degree days (HDDs) as a factor in their calculations. However, the actual storage number exceeded these forecasts, leading to a tempering of the bullish outlook that had been driving prices higher in recent days.
The market's reaction underscored the delicate balance between supply and demand factors in the natural gas sector. While the shut-ins due to Hurricane Isaias had the potential to tighten supply, the larger-than-expected storage build provided a counterbalance, leading to a more cautious approach among traders.
