The number: Sweden's gas storage has plummeted to a critically low level of 10.0%, sparking concerns over energy security. This is based on the Gas Infrastructure Europe's AGSI+ index, which reported a storage level of 9.96% of working volume as of June 21, 2026.
Mechanism context: The AGSI+ index is a key indicator of Europe's gas storage levels, with 9.96% being the observed level on June 21, 2026. This matters because gas storage plays a critical role in ensuring energy security, particularly during periods of high demand. A low storage level increases reliance on imports, which can lead to price volatility.
What to watch next:
- The impact of low gas storage levels on Sweden's energy prices, particularly during the upcoming winter months
- The ability of the Swedish government to secure alternative energy sources, such as imports of 10.2 billion cubic meters in 2025
- The potential for other European countries to follow suit, with storage levels at 10.5% in neighboring countries
- The response of the European Union to address the region's energy security concerns, including the development of new energy infrastructure projects
