Oil Hits $100 and the World Is Already Reeling

$100 Wasn’t Supposed to Happen This Way

Brent crude touched $99 per barrel Tuesday after what amounted to a pincer movement against the world’s most critical energy chokepoints. Saudi Arabia reported explosions at its energy infrastructure, blamed on Houthi fighters, injuring 73 civilians. Hours later, Iranian state media announced strikes on Kharg Island — Iran’s primary oil export terminal — following a U.S. attack on Iranian tankers there.

Two infrastructure nodes. One side of the Persian Gulf. Both under fire. And the market was pricing in something worse than either strike individually: the realization that the Strait of Hormuz, the artery through which more than 20 percent of global energy once flowed daily, is effectively constricted to a trickle.

Four ships transited Saturday. Six on Sunday. Before the war, that number was multiples higher.

The Anatomy of a Squeeze

The attacks came in sequence, each one raising the stakes. The U.S. struck three Iranian oil tankers on Sunday, sinking one, after Iran launched ballistic missiles toward U.S. Navy ships. On Monday, the Houthis hit Saudi energy infrastructure. By Tuesday afternoon, reports of explosions at Kharg Island sent oil spiking for a second time in 24 hours.

This is not a contained conflict anymore. It is a conflict that knows exactly where the pain points are and is hitting them deliberately. Saudi Arabia’s state media called the attackers “terrorists.” The kingdom also condemned Houthi attacks on commercial vessels in the Red Sea, flagging the threat to “freedom of international maritime navigation” — language that signals Riyadh understands the attack on its own infrastructure is part of a broader campaign against the region’s logistics.

The Bab el Mandeb strait, the Red Sea’s southern gateway between the Arabian Peninsula and Africa, saw vessel transits fall 16 percent week over week but still handled more than 260 ships last week — dwarfing the near-stagnant Hormuz traffic. That gap between the two chokepoints matters. Hormuz handles crude. Bab el Mandeb handles a mix of container traffic and some oil. When both are squeezed, the cost multiplier is exponential, not additive.

Who Gets Hit First

At the pump, the damage is already visible but incomplete. The national average gasoline price sits at $4.15 per gallon — up 14 cents in a month, up 6 cents from last week. Diesel has already set a record at $5.90 per gallon. Those numbers look modest compared to what is coming. Brent has risen 36 percent since the war began on Feb. 28, when it traded around $70. Gas prices have risen 40 percent over the same period. The lag between crude and consumer fuel is compressing; when supplies tighten, refiners pass costs through faster.

The bond market moved first, which is how these things usually work. Two-year Treasury yields — the most inflation-sensitive benchmark — hit their highest level since November 2024. The 10-year yield climbed to 4.812 percent, just short of its November 2023 high. Higher oil prices raise borrowing costs for governments and consumers simultaneously. The S&P 500 dipped 0.58 percent and the Nasdaq fell about 0.3 percent — a muted reaction that suggests equities are bracing rather than panicking. Bonds are the canary. Stocks are the bird that hasn’t yet noticed the gas.

What the Banks Are Saying

Goldman Sachs commodities analysts laid out the upside risk plainly: if Persian Gulf oil flows remain at current depleted levels, Brent could exceed $120. Their framing is telling — they call it a “lower-output, higher-price scenario” driven by intensified shipping attacks in both Hormuz and the Red Sea.

HSBC agreed, warning that if diplomacy fails and Hormuz stays this constrained, inventories could draw toward operational lows and Brent could rise to around $120. Their base case is more measured — Brent hovering near $95 through year-end — but they simultaneously revised their longer-term forecasts downward: $85 for 2027 and $75 for 2028 and beyond. In other words, they see a brutal near-term squeeze followed by a structural decline that may never recover those peaks.

Bank of America’s Francisco Blanch offered the starkest range: $95 to $120 if skirmishes curb flows through year-end, and as high as $150 if a broader conflict inflicts major damage on energy infrastructure. That $150 figure is not theoretical armchair forecasting. It is the price of a second Kuwait-style infrastructure war happening inside the Gulf itself.

The Political Geometry

President Donald Trump posted Monday that oil prices will drop precipitously when the U.S. wins the war with Iran, predicting gas could fall to as low as two dollars a gallon. The timing — midterm elections approaching — makes the framing strategic as much as economic. But the inverse logic is equally clear: if prices keep climbing, the political cost falls on the administration regardless of who is blamed for the conflict’s origins.

Iran’s calculus is different. Targeting Kharg Island and striking Saudi infrastructure demonstrates that Tehran and its proxies have the reach to hurt the kingdom’s export capacity and the willingness to use it. The U.S. sinking of an Iranian tanker was a proportional response to ballistic missile fire, but it also signaled that American forces are now willing to attack Iranian economic infrastructure directly — a escalation that makes de-escalation harder for Tehran’s leadership.

What Comes Next

The 400 million barrels of oil released by governments worldwide in early March to ease soaring prices have already been drawn down through spring and summer. Strategic reserves are thinner. The cushion that existed between available supply and demand has shrunk considerably. Every day that Hormuz remains near-empty, that buffer erodes further.

Three scenarios are now on the table, and none of them are comfortable:

A managed de-escalation that restores partial Hormuz traffic would likely hold Brent in the $90-to-$100 range through year-end, consistent with HSBC’s base case. Gas prices would stabilize but not retreat meaningfully.

A protracted low-intensity conflict with intermittent strikes on infrastructure keeps Brent in the $95-to-$120 band, Blanch’s mid-range forecast. Inflation expectationsembed themselves into wage negotiations and central bank pricing models. The 10-year Treasury yield stays elevated. Consumer spending contracts.

A full infrastructure War — major terminal damage, sustained blockage of both Hormuz and Bab el Mandeb — pushes toward $150. That is the domain where recessions stop being predictions and start being consensuses.

The market has priced in the first scenario and is nervously watching for signs of the second. The $100 barrier is psychological as much as it is mathematical. Cross it decisively and the conversation shifts from “how bad is this” to “how long can this last.” Stay below it with volatility and the question becomes whether the damage is already baked into the next quarter’s inflation readings.

Either way, the war started on Feb. 28 with Brent at $70. It is $99 now. The arithmetic of escalation is simple. The politics of stopping it are not.
