Fuel stocks and strategic reserves: What to track
Drained reserves, low gas stores and refill bills ahead
What this tab covers The attributes worth tracking regularly, with the latest value, the direction of travel and why each matters.In 2026 fill levels and release policy matter more than any cost metric: oil reserves were drawn hard and European gas storage entered winter unusually low.
| Category | Attribute | Latest | Trend | Why it matters |
|---|---|---|---|---|
| Security | US SPR fill level | 282.2 million barrels on 16 Oct 2026 (411 million at end 2025); lowest since 198245 | ↘ worsening | Shows how much cushion remains for a further shock and how much must be bought back. |
| Policy | IEA coordinated release policy | Collective action of 11 Mar 2026: 400 million barrels made available (411.9 million in country commitments, calculated; 72% crude); US share includes a 172 million barrel SPR release110 | ↕ volatile | Largest release in IEA history; future refill obligations and any further releases will move prices. |
| Security | EU gas storage fill level | About 75% (74.93%) on 26 Oct 2026, versus 82.9% a year earlier; GIE AGSI data as calculated by TASS, not independently checked7 | ↘ worsening | Low entry into winter raises price and shortage risk across Europe and in LNG markets India buys from. |
| Policy | EU gas storage filling rule | 90% target reachable any time 1 Oct-1 Dec, up to 10 points deviation in difficult markets; rule extended to 31 Dec 2027. Denmark used the flexibility for a 75% target in 202668 | → stable | Looser rules reduce forced summer buying but leave less buffer. |
| Security | India strategic reserve cover | About 9.5 days of net imports in SPRs (about 74 days with company stocks, June 2026); phase 2 of 6.5 Mt planned (Chandikhol 4 Mt, Padur 2.5 Mt) plus 1.75 Mt at Mangalore9 | ↗ improving | Key exposure for Indian portfolio companies and fuel prices. |
| Market | Global oil inventory draw | About 3.8 million barrels/day average since the conflict began, from 8.2 billion barrels pre-crisis2 | ↘ worsening | Commercial and strategic stocks together determine how long markets can absorb the disruption. |
| Compliance | Asset condition and major-hazard compliance | US: GAO (2026) reports a growing SPR maintenance backlog that may restrict fill and drawdown; EU: Seveso III applies from 2,500 t of petroleum products1013 | ↘ worsening | Stocks are only useful if they can be delivered at the rated drawdown. |
| Impact | Lifecycle carbon payback period | Not applicable: stores of fossil fuel do not repay their carbon3 | → stable | Track instead oil demand reduction measures that lower the needed stock size. |
