US Natural Gas Stocks Build Exceeds Expectations

The US Energy Information Administration (EIA) reported a significant build in natural gas stocks, exceeding expectations by 9 billion cubic feet. The storage levels now stand at 40 billion cubic feet, up from 30 billion cubic feet in the previous week.

This increase is notable because it suggests looser balances for the reporting week, which has historically had a negative impact on the front Henry Hub contract when the surprise is of this relative size. However, the direction of natural gas prices may be influenced by other factors, including weather-model revisions and LNG feedgas flows.

The EIA's storage data can be volatile, with weekly changes often being overridden by more significant trends in the running total against the five-year average and prior year. The trajectory of surplus or deficit heading into withdrawal season tends to set the winter risk premium rather than one week's miss.
