$100 oil isn’t as scary as it used to be

By: Kriti Gupta and Nick Roberts

Oil at $100 per barrel has historically been met with stock market sell-offs, a spike in bond yields and uncertainty around the economy. But unlike prior episodes where triple-digit oil prices triggered worries around growth, inflation and the reaction in financial markets, Brent crude’s most recent foray above the $100 mark has wreaked less havoc than usual.

The S&P 500 sits within range of an all-time high, which stands in stark contrast to the initial shock around escalating Middle East tensions earlier this year and triggered a sharp repricing across financial markets. This time around, investors are not reacting to the headline price of oil, but rather the economic signal embedded within it. Today, that signal is far less alarming than $100 oil would traditionally suggest.

Not your grandma’s household budget

Oil prices have largely fluctuated between $80 and $100 per barrel over the last few months, but the largest pressure point remains in crude products. Even with growing refining margins and gasoline prices averaging above $4 per gallon since the conflict in Iran began, consumers have been able to weather the higher prices.

As a percentage of disposable income, gasoline expenditure only sits at about 2.5% – one of the lowest levels in the past 65 years. After several rounds of fiscal stimulus, tariff refunds and tax cuts, households have largely deleveraged to multi-decade lows, creating a larger buffer against higher prices. That better positions them relative to the oil shocks of the 1970s, the commodity boom of the mid-2000s or even the 2022 inflation spike after the war in Ukraine began. The same gasoline price increase that would have meaningfully squeezed household budgets two decades ago or even four years ago now represents a materially smaller drag on spending power.

That doesn’t mean higher energy costs are irrelevant. Consumers at lower-income brackets remain most vulnerable, and prolonged increases in fuel prices can eventually weigh on discretionary spending. But today's energy prices are proving to be less restrictive.

The margin matters

As households are proving more resilient, financial markets are sending a similar message. Financial markets respond to the change in energy prices, not necessarily the level. In March and April, energy markets were forced to price a highly uncertain geopolitical event: the conflict in Iran. The effective closure of the Strait of Hormuz raised the possibility of a meaningful and sustained disruption to global oil supply. Brent surged from roughly $60 per barrel to nearly $120 within a matter of weeks.

At the time, investors were facing a scenario with very little visibility and the significant risk that supply losses could become structural rather than temporary. That uncertainty and doubling of energy prices sent stocks down nearly 10%, only to recover in 11 trading days with oil prices retracing part of their move shortly after.

Even as oil prices have moved higher, investors are no longer pricing a worst-case disruption scenario that would inhibit the economy, and by extension, the stock market. A world where oil is expensive but supply remains available is fundamentally different from one where investors are trying to assess whether a substantial share of global production could disappear overnight.

To be clear, escalation remains a risk. Direct disruption to critical energy infrastructure would likely push oil materially higher and generate a much stronger headwind for risk assets. But for now, investors are viewing oil’s rise as a function of supply constraints rather than a full-fledged energy crisis.

That message is reinforced by the bond market, which isn’t behaving like a major inflation shock is unfolding. Yes, long-term yields show a building correlation with the squeeze in refined products, but are still inching higher, not jumping higher. That does not signal a sharp repricing in interest rates that could jolt the stock market.

Triple-digit oil prices still matter. They can push inflation higher, influence central bank policy and weigh on consumer sentiment. But today’s energy shock looks fundamentally different from past episodes. Consumers are spending a smaller share of their income on fuel, bond markets are not signaling a renewed inflation spiral, and investors are no longer pricing a prolonged supply disruption.

The key variable is no longer the level of oil prices but whether higher energy costs begin to spill over into broader inflation expectations and consumer spending. So far, there is little evidence of that happening, which is why $100 oil – while uncomfortable – is simply not as scary as it once was.
