Refineries must choose which markets to serve when capacity is fixed.
Across Europe, refineries are making a consequential choice — redirecting capacity away from diesel and lubricants toward jet fuel, as the post-pandemic aviation rebound strains global kerosene supplies. Spain's Repsol is leading this pivot, expanding crude sourcing by 11 percent through agreements with Venezuela, Libya, and the United States. The shift speaks to a deeper truth about energy markets: in moments of scarcity, priorities must be declared, and those declarations carry costs for those left further down the list.
- Global aviation's sharp recovery from pandemic lows has outpaced jet fuel supply, creating a structural shortage that refineries can no longer defer addressing.
- Repsol and other European refiners face an impossible arithmetic — total processing capacity cannot expand quickly, so choosing jet fuel means choosing against diesel and lubricants.
- To feed the pivot, Repsol is drawing crude from three continents simultaneously — Venezuela, Libya, and the US — a geopolitical diversification as much as a logistical one.
- Tightening diesel supplies threaten to squeeze European trucking and logistics at a moment when supply chains are already under strain, with Mediterranean tourism caught in the crossfire.
- Repsol's public confidence that fuel demand will not decline signals this is a long-term structural bet, not a short-term emergency measure.
Across Europe's refineries, a quiet but consequential rebalancing is underway. Facilities long devoted to diesel and lubricants are recalibrating toward jet fuel, responding to a tightening global aviation supply that has left airlines competing fiercely for kerosene at premium prices. The choice is a hard one: refineries cannot easily expand total capacity in the short term, so they must decide which markets to serve.
Repsol, Spain's largest energy company, is leading the charge. The firm plans to increase crude oil production by 11 percent, drawing on new supply agreements across three continents — Venezuela, Libya, and the United States. Each source carries its own complexity: Venezuela remains significant despite years of sanctions and economic crisis; Libya has stabilized enough to resume meaningful exports; and the US, increasingly a net energy exporter, offers shale production and strategic reserves. Together, they give Repsol the raw material to boost refining throughput without dependence on any single supplier.
The consequences extend beyond aviation. Redirecting capacity away from diesel risks tightening supplies for European trucking and logistics — sectors already navigating fragile supply chains. Tourism-dependent economies like Spain face a particular tension: more abundant jet fuel benefits airlines, but scarcer diesel strains the ground transport that moves goods and people.
Repsol's stated confidence that fuel demand will not decline suggests the company views the jet fuel shortage as structural rather than temporary. It is a bet that airlines will continue to pay premium prices for kerosene, justifying the reallocation. For European refiners broadly, the episode signals a redrawing of crude supply geography — with Venezuela, Libya, and the US filling roles once held by North Sea and Middle Eastern sources — and raises the open question of whether this rebalancing will prove sufficient to keep both skies and roads adequately fueled.
Across Europe's refineries, a quiet but significant shift is underway. Facilities that once devoted their processing capacity to diesel and lubricants are now recalibrating their operations toward jet fuel, a response to the tightening global supply of aviation fuel. The move reflects a hard choice: as airlines struggle to secure kerosene at reasonable prices, refineries are being forced to choose which markets to serve.
Repsol, Spain's largest energy company, is leading this pivot. The firm has announced plans to increase its crude oil production by 11 percent, a substantial jump that will be fueled by new supply agreements spanning three continents. The company is now receiving crude shipments from Venezuela, securing additional barrels from Libya, and drawing on reserves from the United States. This diversification of sources is meant to give Repsol the raw material it needs to boost overall output and meet the surging demand for jet fuel without sacrificing other products entirely.
The timing is not accidental. Global aviation has rebounded sharply from pandemic lows, and the supply of jet fuel has not kept pace. Refineries worldwide are facing a bottleneck: they cannot easily expand their total processing capacity in the short term, so they must choose where to allocate what they have. Jet fuel, essential to the airline industry and commanding premium prices, has become the priority. Diesel and lubricants, by contrast, face softer demand or can be sourced from alternative suppliers.
For Repsol, the strategy hinges on securing crude from multiple geographies. Venezuela, despite years of economic crisis and international sanctions, remains a significant oil producer. Libya, after years of civil conflict, has stabilized enough to resume meaningful exports. And the United States, with its shale production and strategic reserves, offers another reliable source. By tapping all three, Repsol aims to have enough raw material to increase refining throughput without depending on any single supplier.
The consequences ripple outward. A reallocation of refinery capacity away from diesel production could tighten supplies of that fuel in Europe, affecting trucking, logistics, and ground transportation at a moment when supply chains are already fragile. Tourism, particularly in Spain and other Mediterranean destinations, depends on both aviation fuel and ground transport. If jet fuel becomes more abundant while diesel becomes scarcer, the balance shifts in favor of airlines and against the broader economy that moves goods and people by truck.
Repsol's confidence in this strategy suggests the company believes the jet fuel shortage is structural, not temporary. The company has publicly stated it does not expect a decline in fuel demand, signaling that it sees sustained pressure on aviation fuel supplies for the foreseeable future. This is a bet that airlines will continue to compete fiercely for kerosene, and that the premium prices they are willing to pay justify the reallocation of refinery resources.
The broader picture is one of energy markets adjusting to new realities. Global supply chains for crude oil are being redrawn, with European refineries now looking beyond traditional North Sea and Middle Eastern sources. Venezuela and Libya, countries that had fallen out of favor in recent years, are being brought back into the supply equation. And the United States, increasingly a net energy exporter, is playing a larger role in European energy security. For Repsol and other European refiners, the question is whether this rebalancing will be enough to keep both aviation and ground transport adequately fueled.

La Conversación del Hearth Otra perspectiva de la historia
Why would a refinery choose to make less diesel if diesel is still needed across Europe?
Because jet fuel commands higher prices right now. When you can only process so much crude, you chase the margin. Airlines are desperate for kerosene, and they'll pay for it. Diesel demand is softer by comparison.
So this is purely about profit, not about some physical constraint?
It's both. Yes, refineries want to maximize returns. But there's also a real supply crisis in jet fuel. The aviation industry rebounded faster than refinery capacity could expand. You can't build a new refinery in a year. You work with what you have.
What happens to Spain's tourism if diesel becomes scarce?
That's the tension nobody wants to talk about. You need trucks to move goods to hotels, restaurants, airports. If diesel gets tight, those costs rise. It's not a direct hit to tourism, but it's a squeeze on the whole system that supports it.
Why is Repsol suddenly able to get crude from Venezuela and Libya?
Venezuela never stopped producing oil, but sanctions and politics kept it isolated. Libya stabilized enough to resume exports. And the US has shale. Repsol is essentially saying: we'll source from anywhere we can to get the volume we need. It's a pragmatic response to a tight market.
Does this mean the jet fuel crisis is permanent?
Repsol's betting it will last long enough to justify restructuring their whole operation. They're not hedging. They're committing to the idea that airlines will keep paying premium prices for kerosene for years. That's a significant statement about where they think energy markets are headed.
