Stocks Climb to Records Even as Oil, Yields and Volatility Rise Together

U.S. equities pushed to fresh record highs on Monday, shrugging off a simultaneous surge in crude oil prices, Treasury yields, and equity volatility that would have sunk risk appetite in any normal cycle.

The S&P 500 and Nasdaq Composite each gained roughly 0.2 percent, extending a rally that has confounded strategists who expected the escalating Iran conflict and its resulting oil-supply shock to finally break the two-year-old bull market. The Dow Jones Industrial Average edged higher as well, leaving all three major indices at or within striking distance of all-time peaks.

“This market continues to trade like a machine that has accepted geopolitical instability as a permanent background hum rather than an existential threat,” said Stephen Innes, a market analyst at Investing.com.

The disconnect between equities and the macro backdrop is the widest it has been since the early weeks of the Iran crisis.

West Texas Intermediate crude settled at $98.07 a barrel on May 11, up 2.78 percent from the prior session. Brent crude climbed 2.88 percent to $104.21. The Strait of Hormuz, through which roughly a fifth of the world’s seaborne oil passes, has been effectively closed for the better part of two months as U.S. and Iranian forces exchange strikes on vessels and naval assets.

Some 1 billion barrels of global supply have been lost to the disruption, according to BBC News, and most energy analysts now expect crude to remain above $100 a barrel through at least the end of the year.

Saudi Aramco chief executive Amin Nasser reinforced that outlook, warning that global spare production capacity is thin — a constraint that limits how far crude can retreat even if a diplomatic opening materializes. That opening is not near. President Donald Trump rejected an Iranian ceasefire proposal over the weekend, calling it “totally unacceptable” and signaling that Washington’s military campaign would continue.

“The narrative has changed again from de-escalatory to escalatory in a matter of a few days and oil markets respond to it,” said Florence Schmit, an energy strategist at Rabobank.

Bond Market Sends a Different Signal

While equities are pricing resilience, the bond market is telling a less sanguine story. The yield on the benchmark 10-year U.S. Treasury note has climbed to 4.41 percent, tightening financial conditions at a moment when stock valuations are already stretched by historical measures. Wall Street’s fear gauge, the Cboe Volatility Index, has ticked higher alongside it — an unusual co-movement that indicates investors are hedging tail risk even as they keep bidding up stocks.

Rate futures now price in fewer than two full quarter-point cuts from the Federal Reserve in 2026, down sharply from the four to five reductions that traders had penciled in at the start of the year. With crude above $100 and core inflation running stubbornly above the central bank’s 2 percent target, the case for easing is evaporating.

“The market is slowly being forced to confront an uncomfortable possibility that many hoped to avoid,” Innes said. “The Fed may remain pinned on hold for far longer than equity valuations currently imply.”

An Unstable Equilibrium

That narrow foundation is itself a source of risk. Gains remain concentrated in a handful of megacap technology and AI-linked names, while energy stocks — which would normally benefit from triple-digit oil — have been held back by fears that the Hormuz closure will eventually choke global demand. Small-cap and cyclical shares, the traditional bellwethers of economic optimism, have lagged.

This configuration — rising oil, climbing yields, and elevated volatility alongside record equity prices — has few historical parallels that ended well. Consider the 1990 Gulf War build-up, when a commodity spike and geopolitical shock eventually broke equities higher only after hostilities began. By contrast, the 2008 commodity surge and the early months of the 2022 Russia-Ukraine conflict both saw stock markets buckle under the combined weight of fixed-income and energy-market pressure.

Bulls counter that the U.S. economy entered this disruption from a position of genuine strength. Earnings, for their part, continue to beat Wall Street estimates. Spending has held up despite the inflation pulse from higher fuel costs. And the AI investment cycle is generating productivity gains that could offset some of the drag from pricier inputs. Put bluntly, the market’s resilience may not be denial — it could be a rational bet that the real economy can absorb the shock.

Whether that argument holds depends on variables no trading desk can control: the trajectory of the Iran conflict, the durability of the consumer as savings dwindle, and the path of core inflation over the next three months. If oil stays above $100 and the Fed remains on hold, the rate-sensitive corners of the market — housing, small caps, highly levered corporates — will face a reckoning that the megacap indexes have so far sidestepped. For now, the machine is still running. The volume on the background hum, however, keeps rising.
