For Investors, the Real Risk Isn’t $100 Oil

Investors tend to fixate on round numbers. The Dow Jones Index at 50,000, the S&P 500 approaching 8,000, and for the purposes of this article, crude oil at $100 per barrel. The price of crude oil is particularly salient, as the $100 number conjures memories of past energy shocks, when rapidly rising fuel costs squeezed consumers, pushed inflation higher, and raised fears of slowing economic growth.¹

But is $100 oil really something to fear?

To break it down, let’s start with what that price point actually means. $100 today is not the same as $100 when Brent first crossed that threshold in 2008. The Consumer Price Index has increased by roughly 57% since February 2008. Adjusted for that inflation, $100 oil in 2008 would be equivalent to approximately $157 today. Viewed the other way around, $100 oil today has roughly the same purchasing-power impact as $64 oil did in early 2008.

There is another very important difference between previous decades of higher oil and today: American households are arguably better positioned to absorb higher fuel costs, even though no one likes to see higher prices at the pump.

The S&P 500 Averaged 6.06% a Year While Average Fund Investor Got 4.25%

That’s Dalbar’s count for the 20 years ending December 31, 2019, and according to the firm, most of that gap came from behavior: selling on the way down and chasing whatever just went up. Owning an index fund doesn’t fix that. You still decide what to hold and whether to sit still when oil doubles in a few weeks.

Today, gasoline spending currently represents only about 2.5% of disposable personal income, near the low end of its range over the past 65 years. Around 1980, that share was above 5%, as the nearby chart shows.

Spending on Gas and Other Energy Goods Divided by Disposable Personal Income

In the second quarter of 2026, U.S. spending on gasoline and other energy goods ran at an annualized rate of about $529 billion, compared with roughly $23.6 trillion of disposable personal income. By some estimates, gasoline prices would now need to rise above $10 per gallon for the burden on household income to resemble what consumers experienced during that period.

That brings us to what we think is the more useful way to frame the risk: not the $100 level itself, but the speed and circumstances under which oil gets there.

Earlier this year, Brent crude roughly doubled from around $60 to nearly $120 per barrel within a matter of weeks, as markets grappled with the possibility of a major and sustained disruption to global oil supplies. Stocks fell nearly 10% during that period, in response to the shock.

But those losses also proved short-lived.

As investors gained more clarity about the supply outlook, stock indexes recovered relatively quickly. More importantly, energy prices have remained elevated for much of the year since then, giving households, businesses, and financial markets time to adjust. And that’s precisely what we’ve seen—nominal U.S. GDP reached an annualized $32.5 trillion in the second quarter, up from $30.5 trillion a year earlier, while the S&P 500 remains near its all-time high and oil prices also remain elevated.

This is not to say that high oil prices are harmless. Persistently higher energy costs can still pressure household budgets, raise transportation and production expenses, and complicate the inflation outlook. Another sudden supply disruption could also change the picture quickly. But we think the experience of the past several months reinforces the idea that the economy can adapt to higher oil prices. What tends to be more disruptive is a rapid price shock combined with uncertainty about whether enough oil will be available at all.

Bottom Line for Investors

Markets love round numbers, but economies do not operate according to them. $100 oil certainly sounds expensive, particularly for investors who remember earlier energy crises. But the U.S. economy is different today; households devote a smaller share of their income to fuel, and $100 buys considerably less than it did when oil first reached that level nearly two decades ago.

We think investors should look downstream and stick to fundamental analysis when gauging the impact of higher oil prices. Are consumers pulling back? Are corporate margins deteriorating? Are inflation expectations moving materially higher? Are financial conditions tightening as a result? So far, the answer to each of those questions appears to be no.

Stop Settling for Average Market Returns

Anyone can buy an ETF and own the S&P 500. But there’s a tradeoff: a purely passive strategy can’t outperform the market, because it is the market. Zacks Advantage takes a different approach with an actively managed robo-advisor that:

• Invests exclusively in ETFs
• Builds a mix of equity and bond ETFs around your goals and risk tolerance
• Keeps fees and expenses low
