US EIA data shows a natural gas storage build of 103 billion cubic feet for the week ending 17 April. The forecast was 96 billion cubic feet.
The actual increase was 7 billion cubic feet higher than expected. This indicates a larger weekly stock build than the market estimate.
Near Term Market Impact
The natural gas injection of 103 billion cubic feet (Bcf) was significantly higher than the 96 Bcf forecast, signaling a well-supplied market. This bearish data point will likely put immediate downward pressure on front-month futures contracts. We should prepare for a test of lower price supports in the coming trading sessions.
This injection is substantially larger than the 5-year average for this week in April, which is closer to 60 Bcf. As of today, this puts total working gas in storage at over 2,410 Bcf, representing a surplus of nearly 35% against the historical average. This massive cushion limits the upside potential for prices heading into the summer.
Even with strong demand from LNG export facilities, robust domestic production continues to flood the market with supply. Looking back from our perspective in 2025, the market then was far more concerned with supply adequacy. This year, the persistent glut is the dominant theme we must trade against.
For derivatives traders, this reinforces a bearish outlook, making it attractive to sell call option spreads on the June and July contracts to capitalize on range-bound price action. We could also consider buying puts or initiating put spreads to profit from a further slide in prices. The data suggests that any price rallies are likely to be short-lived and met with selling pressure.
Trading And Volatility Considerations
This report will likely suppress near-term price volatility, which makes selling premium an attractive strategy for us. We need to monitor upcoming weather forecasts for any signs of early summer heat that could boost demand. However, until this supply surplus begins to shrink meaningfully, the path of least resistance for prices remains lower.
