NEW YORK — Global oil prices surged Friday, with Brent crude closing above $100 a barrel for the first time since August 2022 as the conflict involving Iran and the near-halt in tanker traffic through the Strait of Hormuz rattled investors, dragged stocks lower and forced traders to rethink how quickly the Federal Reserve can cut interest rates, March 13. The spike revived fears of a fresh inflation shock just days before the Fed’s next policy meeting, raising the risk that policymakers stay cautious even as growth shows signs of softening.
By late Friday, Brent had settled at $103.14 a barrel and West Texas Intermediate at $98.71, while the S&P 500 fell 0.6% and the Nasdaq dropped 0.9% as the dollar strengthened and Treasury yields stayed elevated. The move underscored how quickly energy stress can spread beyond commodities and into broader risk assets when traders start pricing in a longer geopolitical shock.
Why oil prices above $100 matter for the Fed
The immediate concern is inflation. By Friday, fed funds futures were pricing in slightly less than one quarter-point cut by December, a sharp retreat from expectations for two quarter-point cuts late last month. In other words, a market that had been leaning toward easier policy is now bracing for the possibility that higher fuel costs keep price pressures sticky for longer.
The anxiety starts with geography. About 20 million barrels a day moved through the Strait of Hormuz in 2024, equal to roughly one-fifth of global petroleum liquids consumption, and there are limited alternatives if the waterway remains heavily constrained. That makes every disruption in the strait matter far beyond the Gulf, especially for refiners, airlines, shippers and central banks already trying to navigate a fragile inflation backdrop.
Officials are trying to contain the damage, but traders are not yet convinced the response will be enough. Washington has announced a 172 million-barrel release from the Strategic Petroleum Reserve as part of a broader emergency effort with other major consuming nations. Even so, reserve barrels can buy time, not certainty, if physical flows through Hormuz remain impaired and insurers, shipowners and refiners stay cautious.
That is why some banks are treating the move as a violent shock rather than a permanent new baseline. Goldman Sachs lifted its average March Brent forecast to above $100 while still projecting that prices could ease later in the year if disruptions do not deepen. For now, though, markets are trading the immediate scarcity risk, not the eventual normalization story.
What this means for markets and consumers
For equity investors, the danger is not just higher crude prices but what they signal. More expensive energy can push up gasoline, diesel, jet fuel and freight costs, squeezing household spending and corporate margins at the same time. That combination helps explain why stocks sold off even as some investors had hoped weaker economic data would keep the door open to faster Fed easing.
If oil stays elevated, the pressure will not be limited to Wall Street. Transport-heavy sectors, manufacturers and consumer-facing businesses would all face a tougher pricing environment, while central bankers would have to decide whether an energy-driven inflation impulse is temporary noise or the start of a broader second-round problem. That is the policy bind markets are starting to price in now.
Oil prices have seen pieces of this script before
Markets have seen fragments of this story before, from the tanker attacks near the Strait of Hormuz in 2019 and the oil spike after Russia’s invasion of Ukraine sent crude back above $100 in 2022 to the Red Sea disruptions that kept a geopolitical premium in energy markets in early 2024. What feels different this time is the combination of direct supply losses, infrastructure damage and a bottleneck at one of the world’s most critical energy chokepoints.
The next move now depends on three variables: whether military escalation intensifies, whether tanker traffic through Hormuz begins to recover and whether the Fed signals it can still ease policy this year without reigniting inflation concerns. Until markets get clearer answers on all three, oil is likely to remain the main driver of global risk sentiment.
That leaves investors with a simple but uncomfortable conclusion: if crude holds near or above triple digits, the Iran conflict may stop being treated as a short-lived geopolitical scare and start being priced as a broader macroeconomic problem. And once that shift takes hold, it becomes much harder for markets to count on quick rate cuts to cushion the blow.
