Oil prices are surging on the back of the Iran war. Fears of a sustained disruption to Strait of Hormuz supply are driving the move. The parallels to the 1970s oil crises are everywhere.

But UBS economist Arend Kapteyn is pushing back on the comparison. His argument is simple: the global economy is built differently now. Oil just does not hit the way it used to.

The note, which circulated this week, makes a case that investors watching energy markets need to understand. The fear driving oil prices higher may be real. The economic damage that fear implies could be significantly overstated.

The number that changes everything

Kapteyn’s central argument is about what economists call oil intensity. That is the amount of oil a country needs to produce a given unit of economic output. And that number has fallen dramatically since the 1970s.

• The world’s biggest gas field matters just as much as oil right now
• Goldman Sachs reveals top oil stocks to buy for 2026
• U.S. economy will show resilience, despite rising oil prices

In the United States, oil spending as a share of GDP stood at roughly 4.8% in 1974. Today it sits at approximately 1.7%. That is not because the US uses dramatically less oil in volume terms.

It is because the economy has grown so much larger while oil consumption has barely moved. GDP has grown nearly twentyfold since 1974. Oil consumption in 2024 was only slightly above 1974 levels.

The practical implication is stark. Even if oil prices hit $100 per barrel, UBS estimates US oil spending would only reach around 2% of GDP. That is a manageable number. It is nowhere near the economic chokehold oil had in the 1970s.

Europe tells the same story

The United States is not alone in this shift. UBS found that Europe has followed a similar path, arguably faster. The EU’s oil spending fell from approximately 3.7% of GDP in 1974 to roughly 1.8% in 2024. Europe got there through a combination of slower GDP growth and larger gains in energy efficiency.

The direction of travel is the same across the developed world. Economies have been quietly decoupling from oil for decades. Each unit of economic output requires less and less of it. That structural shift is the core of UBS’s argument.

Why the 1970s comparison breaks down

The 1970s oil shocks were devastating because oil was deeply embedded in every part of the economy. Home heating, manufacturing, transportation, electricity generation. Oil was everywhere. When it became scarce and expensive, the pain was immediate and broad.

That is no longer the structural reality. Natural gas replaced oil in home heating across much of the developed world. Electricity generation moved away from oil. Fuel efficiency in transportation improved substantially over five decades.

The economy adapted. And those adaptations compounded over time.

Kapteyn also pointed to a striking statistic from the International Energy Agency. The IEA’s head noted that more oil supply has been lost in the current Middle East conflict than in both 1970s oil shocks combined. That is a remarkable fact. But the economic impact is unfolding very differently, precisely because the economy’s dependence on oil is so much lower today.

What this means for investors right now

The UBS note carries a direct implication for how investors should think about the current oil price surge. Several things follow from the oil intensity argument:

• Recession fears tied to oil prices may be overblown. If oil spending as a share of GDP peaks around 2% even at $100 per barrel, the drag on consumer spending and corporate margins is real but contained. The stagflation playbook from the 1970s does not apply cleanly.
• Inflation risk is more limited than the headlines suggest. A smaller GDP share means a smaller transmission into broader prices. The Fed is watching unemployment more than oil, and the data supports that approach.
• The supply disruption risk is real even if the macro damage is not. Strait of Hormuz restrictions can spike oil prices sharply in the near term. That creates volatility even without economic collapse. Traders and investors in energy-exposed assets should expect turbulence.
• Energy efficiency is a long-term structural story. The oil intensity decline did not happen overnight. It reflects decades of investment in efficiency, technology, and fuel substitution. That trend is not reversing.

The broader takeaway from UBS is not that oil prices do not matter. They do. Higher energy costs hit consumers, compress margins for transportation companies, and create real friction. But the channel from oil prices to macroeconomic catastrophe is far narrower than it was fifty years ago.

The global economy has spent decades quietly building resilience. That resilience is only visible when the pressure test arrives. That test is happening now. And so far, the structure is holding.
