A Spanish business can buy gas from outside the Persian Gulf and still be affected when other buyers seek replacement cargoes. That market connection is different from the quantity of Qatari gas Spain received. Confusing them turns a supply share into an unwarranted assurance of protection against prices.
The comparison with Europe introduces another problem. Enagás reports Spanish physical supplies in energy units. The 8.9% attributed to Qatar in Eurostat's news article concerns the monetary value of the EU's extra-EU LNG imports in 2025. It is not a share of physical volume, European consumption or all energy imports. Dividing it by a Spanish supply share would not yield a valid measure of relative risk.
Start with what entered the Spanish system
The Spanish Gas System Report 2025 puts total physical supplies at 372,498 GWh, covering pipeline gas and LNG. Its map attributes 6,403 GWh to Qatar as LNG supply. A GWh measures energy, not vessel numbers or spending in euros.
Using those quantities, our quotient is 6,403 ÷ 372,498 × 100 = 1.718935…%. It describes the volume attributed to Qatar as a share of total supplies in that release. It is not the share of domestic consumption, which has a different denominator, or the proportion of gas that would be lost during a disruption.
Changing just one part of the calculation shows why the question matters. Keep the same 6,403 GWh but use only the 248,084 GWh of LNG supplies reported on the same page, and the result is 2.580981…%. The quantity attributed to Qatar has not increased. The reference group has become smaller.
One numerator, two physical denominators
The difference the report does not fully explain
The Enagás diversification chart on page 25 shows 1.735% for Qatar in 2025. That does not match the 1.718935…% calculated from the map and total. The gap is approximately 0.016065 percentage points. These are percentage points, not an estimate of lost energy.
We looked for another check within the publication. Page 80 links to an official physical-operation workbook. In its “Pág. 25” sheet, cell E12, identified as Qatar and 2025, contains the fraction 0.01718890770907905. Converted to a percentage, it is 1.7188907709…%. Both that value and our quotient display as 1.719% to three decimal places, although their full values are not identical.
The discrepancy, without a confirmed cause
The workbook is close to the quotient from the physical quantities, but it does not explain why the PDF shows 1.735%. The report warns that some figures are provisional and that SL-ATR takes precedence in a discrepancy. That general warning does not establish the cause of this particular case. We found no specific reconciliation in the documents examined. We do not attribute the difference to rounding, a revision, a different basis or an error.
Requiring the quantities to fit provides a second way to expose the issue. Applying 1.735% to 372,498 GWh would imply 6,462.8403 GWh, or 59.8403 GWh more than the map. This is a hypothetical equality check, not evidence of additional cargoes, losses or a volume needing replacement. We retain all three readings with their provenance rather than selecting a definitive official figure.
The European share answers a different question
Eurostat's news article of 25 March 2026 rounds Qatar's share to 8.9%. The original annex, sheet “VISUAL 2”, gives 8.855309243451158% and explicitly identifies trade by value. The product is LNG, CN code 27111100, and the scope is imports from outside the EU during 2025.
A monetary share combines quantities and prices. It can change without physical volume moving in the same proportion. The European denominator also covers only LNG imported from third countries, while total Spanish supplies include pipeline gas. Restricting Spain's denominator to LNG addresses one product difference. It does not turn euros into GWh or, by itself, harmonise the statistics.
| Source and period | Unit and denominator | What it describes | What it does not measure |
|---|---|---|---|
| Enagás · 2025 | GWh; Spanish physical pipeline-gas and LNG supplies | Attributed supply origin | Consumption, costs, each vessel route or lost gas |
| Eurostat · 2025 | % of the value of EU extra-EU LNG imports | Qatar’s share of that import spending | GWh share, European consumption or all energy |
| Observatory calculations | Quotients of published quantities; separate units | Denominator effects and a documentary discrepancy | An official corrected share or vulnerability ranking |
Origin, passage and economic exposure
The origin attributed to a supply entry describes its statistical provenance. It does not reconstruct each vessel's loading port, dates and actual route. The IEA's Hormuz factsheet, dated February 2026, explains the corridor's importance to Qatari LNG exports. That geographical context does not make the Enagás map a record of verified voyages or assign its volumes to a particular day.
Measuring direct exposure by route would require linking origins, cargoes, destinations and periods without double-counting reloads or re-exports. Measuring an actual disruption would additionally require identifying missing deliveries, replacements and available stocks. Neither percentage does that work on its own.
The effect can reach purchases from outside the Gulf
Possible economic mechanisms; no newly quantified impacts.
If some supply became unavailable, buyers in different countries could compete for alternative cargoes. Replacement prices and availability on a particular date could also change for buyers sourcing elsewhere. The IEA factsheet describes that international transmission in LNG markets. Its effect in Spain would depend on contracts, destination flexibility, hedging, inventories and demand.
Infrastructure adds a separate condition. The ability to unload or regasify LNG does not guarantee that an uncommitted cargo exists, arrives in time or can reach the place where it is needed. Nor does a higher Qatari share automatically rank two economies by vulnerability. The duration of the disruption, alternatives and scope for adjustment also matter.
We have not assembled contracts, acquisition prices, elasticities or substitution balances with which to estimate household bills, inflation or unserved consumption. We therefore provide no numerical forecast and do not claim that Spain is a particular multiple safer than the EU.
What would make the comparison useful
The first step would be Spanish and EU series covering the same product, period and physical unit, with compatible definitions of imports and supplies. Eurostat's annex also provides shares by net mass; physical statistics are not wholly absent. They still need a comparable energy basis, documented conversions and calorific values, with entries, re-exports, storage and consumption kept distinct. An update would also require identified releases and cut-off dates.
Actual routes would then need verification, and delivery exposure would need to remain separate from price risk. The monitor archives record system decisions, not Spanish imports. The analysis of closure, passage and flows separates voyages from volumes. This third report adds another distinction: the origin of gas and the cost of securing it call for different statistics.
The practical conclusion is to ask for the denominator whenever a percentage is quoted. The documents examined allow us to describe historical quantities attributed to Qatar, investigate a discrepancy and explain economic transmission channels. They do not turn those shares into a current, comparable measure of the damage a Hormuz disruption would cause.
