IBEX 35 and Expensive Oil: Which Spanish Stocks Are Hurting the Most

Against the backdrop of escalating tensions in the Middle East and a spike in Brent, Spanish stocks first fell sharply along with the rest of Europe, then tried to rebound as oil pulled back and the market saw a chance of de-escalation. On March 9, the IBEX 35 closed down 0.76%, while Brent traded around $100 that day after a sharp intraweek jump. A few days earlier, the Spanish index had posted one of the steepest declines among Europe’s major markets.

Why Expensive Oil Matters So Much for the Spanish Market

For Spain, rising oil is not just a commodities story. It is a hit to airlines, tourism, consumer spending, and inflation expectations. As the war intensified and oil jumped, airline stocks in Europe and Asia came under heavy pressure.

This matters especially for the IBEX 35 because the Spanish market is sensitive to sectors that quickly feel the impact of higher fuel costs and weaker consumer confidence. When oil rises sharply, the market starts to fear not only higher costs, but also weaker demand across the domestic economy. Against the broader European backdrop, the financial-heavy IBEX posted its sharpest one-day drop since the tariff shock in April.

Which Spanish Stocks Are Suffering the Most

1. Airlines and the Travel Segment

This is the first and most obvious risk group. When oil rises, the market almost automatically hits airline stocks because fuel is one of their largest cost items. Ticket prices on some routes began rising sharply amid fears of a prolonged conflict and more expensive jet fuel.
This is especially sensitive for Spain because of the importance of tourism. If expensive oil persists, the market starts pricing in not only rising airline costs, but also a broader hit to the entire tourism demand chain — from carriers to consumer services.

2. Consumer Stocks

When energy becomes more expensive, investors quickly revise expectations for consumer spending. Consumer discretionary across Europe fell more sharply than the broader market because investors were pricing in both supply-chain disruption and weaker demand. For Spain, this is logical: if households are forced to spend more on fuel and basic expenses, discretionary spending is one of the first things to weaken.

3. Transport and Logistics

The second direct risk group after airlines is companies tied to transportation and the movement of goods. The problem here is not just the cost of fuel, but overall business margins. The longer oil remains high, the more the market starts to question the sustainability of profits.

4. Banks — Not Always Direct Victims, but the Market Punishes Them Too

One feature of Spain is that the IBEX 35 has a significant weighting in financials. That makes the reaction less linear. On the one hand, banks can look more resilient than some cyclical sectors. On the other hand, in a risk-off environment the market often sells financial-heavy indices as well.

Who in Spain Can Benefit From Expensive Oil

There is also an obvious beneficiary in the Spanish market: Repsol. The company raised its shareholder payout targets and increased its production target while reducing total investment spending. For the market, that is an important signal: expensive oil supports the cash flow of companies like this even when the broader index is under pressure.

In a high-oil environment, the Spanish market splits in two: transport, travel, and consumer-related segments look weaker, while oil and gas stories can appear relatively stronger.

Is It Time to Buy Spanish Stocks Now?

It makes more sense to split the question in two.

If oil quickly returns to calmer levels and the Middle East story loses urgency, part of the Spanish market may start to look oversold.

But if expensive oil becomes entrenched, the Spanish market remains vulnerable. In that case, travel, transport, and consumer-sensitive names are likely to look weakest — not every part of the index equally, but those segments in particular.
