The energy crisis is rapidly spilling over from commodity markets into the broader economy, with the aviation sector emerging as the first major casualty. On Wednesday, Europe's largest low-cost carrier, Ryanair, announced it is cutting its winter capacity. The airline warned that if jet fuel prices remain elevated, European airlines will face significantly higher cost pressures, potentially leading to "substantial fare increases" on short-haul routes next year.

Ryanair stated it has already hedged approximately 80% of its fuel requirements, making it one of the industry's most hedged airlines. However, it still faces exposure to jet fuel prices equivalent to $140 per barrel. In response to the high oil price environment, the company has chosen to proactively reduce its winter flight schedule to lower fuel expenses, a move expected to save between €70 million and €100 million (approximately $81 million to $116 million).

This decision sends a telling signal: when an airline that has already locked in most of its fuel costs still needs to cut capacity to protect profitability, the energy price shock is no longer just a trading theme in commodity markets—it is now materially influencing corporate operational decisions.

Moreover, the pressure on the aviation industry is not confined to rising crude oil prices. Ongoing tensions around the Strait of Hormuz are simultaneously pushing up prices for gasoline, diesel, jet fuel, and European natural gas. This makes it difficult for companies to ease cost pressures through a simple pullback in crude prices. Brent crude remains near $95 per barrel, with a year-to-date gain of over 55%.

Where the pressure originates

Ryanair's capacity cut vividly illustrates how energy prices are transmitting into airline profit margins. The company has hedged roughly 80% of its jet fuel needs, but the remaining portion is still exposed to the high-price environment. Rather than operating its full schedule amid soaring fuel costs, Ryanair has opted to scale back capacity to protect its cost structure and margins.

Jeff Currie, a senior advisor at Carlyle Group and a well-known commodities analyst, has previously warned that markets may be underestimating the strain in the refined products sector. In an interview on August 18, he said the market's focus should extend beyond crude oil, noting that consumers ultimately use gasoline, diesel, and jet fuel—and the supply-demand dynamics in these refined product markets look "far uglier."

This implies that even if crude prices were to retreat later, the cost burden on airlines may not ease in tandem.

Renewed Hormuz tensions: shockwaves spreading from crude to refined fuels

The situation in the Strait of Hormuz remains the core variable driving the current energy price surge. Negotiations over transit issues have repeatedly broken down, continuously denting market expectations for a swift de-escalation.

Rich Privorotsky, head of One Delta trading at Goldman Sachs, noted in a daily client briefing on Tuesday that previous oil price spikes were typically followed by intervention, diplomatic efforts, or other forms of cooling measures. However, recent developments mark a shift: the U.S. struck Iranian targets after oil prices had already risen and during trading hours, further intensifying market anxiety.

More notably, the impact is no longer limited to crude. Privorotsky said that even if Washington subsequently takes steps to de-escalate, crude is only part of the problem, as distillates, gasoil, diesel, and European natural gas prices have all broken through key levels.

For airlines, this means the real threat to watch is not just Brent crude, but the sustained pressure on refining and refined product markets that could further push up jet fuel prices.

Limited policy cushion: low U.S. strategic reserves

The relentless rise in oil prices is also putting mounting pressure on the U.S. government. U.S. Energy Secretary Chris Wright said Tuesday that around 17 million barrels of crude were still transiting the Strait of Hormuz daily, a figure not markedly lower than the pre-crisis average of roughly 20 million barrels per day. However, Privorotsky believes this data remains highly contested.

Treasury Secretary Bessent, meanwhile, suggested that as onshore pipeline routes gradually bypass the Strait of Hormuz, the waterway could become "worthless" within two years.

In the near term, however, the U.S. policy buffer is limited. Strategic Petroleum Reserve inventories have fallen to about 286 million barrels, well below the maximum capacity of roughly 730 million barrels and nearing the operational safety range of 250-300 million barrels estimated by market analysts.
