Crude Hits $111 as Hormuz Blockade Enters Third Month, Forcing Fed Into Stagflation Trap
Two-month closure of Strait of Hormuz has removed 20% of global oil supply, pushing Brent crude to $111 and US gasoline to four-year highs while negotiations remain deadlocked.
Brent crude reached $111 per barrel on 28 April as the US-Iran blockade of the Strait of Hormuz entered its third month with no resolution in sight, creating what analysts now call the largest oil supply disruption in history.
The closure, which began 28 February following US-Israel strikes that killed Iranian Supreme Leader Ali Khamenei, has effectively halted 20 million barrels per day of crude flows through the strait — roughly 20% of global supply. Production shut-ins averaged 7.5 million barrels per day in March and are expected to peak at 9.1 million barrels per day in April, according to the US Energy Information Administration. Physical crude prices have spiked to $150 per barrel in some markets, far exceeding futures prices, as buyers scramble for alternative supplies.
Negotiation Stalemate Deepens Market Anxiety
US Secretary of State Marco Rubio ruled out any framework that would grant Iran control over Strait transit, telling reporters that Washington “cannot normalize a system in which the Iranians decide who gets to use an international waterway and how much you have to pay them to use it,” per CNBC. Iranian First Vice President Mohammad Reza Aref countered that “the security of the Strait of Hormuz is not free” and that Tehran will not accept restrictions on its own oil exports while providing free passage to competitors.
The impasse has left Gulf producers storage-limited and forced into shut-ins. Saudi Arabia, UAE, Iraq, and Kuwait cannot export their crude and face rapidly filling storage capacity. Analysis from Kpler suggests Iran itself could exhaust storage capacity within 12 to 22 days if the blockade persists, according to Al Jazeera, though Iranian exports averaged 1.71 million barrels per day in April despite the naval cordon — evidence that some crude is reaching buyers through alternative routes or sanction-busting channels.
Inflation Pressures Mount as Fed Options Narrow
The energy shock is cascading through the US economy at the worst possible time for monetary policy. US gasoline prices hit $4.18 per gallon on 28 April, up $1.19 from late February — a 40% increase in two months, reported Egypt Oil & Gas. March producer price index figures exceeded 4% year-over-year, and Federal Reserve Chair Jerome Powell has stated explicitly that rate cuts are off the table without clear progress on inflation.
“This is still the largest oil supply shock in the history of the oil market.”

Goldman Sachs analysts warned that “economic risks are larger than our crude base case alone suggests because of the net upside risks to oil prices, unusually high refined product prices, products shortages risks, and the unprecedented scale of the shock,” per The National. The bank now forecasts oil could approach $120 later in 2026, though its Q4 estimate remains $90 for Brent and $83 for WTI — assumptions that may prove conservative if the blockade extends beyond current forecasts.
The Fed faces a 1970s-style stagflation dilemma. Spiking energy costs are pushing inflation upward while simultaneously destroying demand, particularly in Asia, which receives 84% of Hormuz crude flows. Raising rates to combat inflation risks accelerating an economic contraction; holding steady allows inflation expectations to de-anchor. Rate cuts to support growth would undermine inflation credibility. There are no good options.
Manufacturing and Supply Chain Contagion
Beyond crude oil, the Hormuz closure has disrupted 46% of global urea trade (fertilizer), methanol flows critical to plastics production, and synthetic graphite shipments used in electric vehicle batteries, according to analysis from the World Economic Forum. Semiconductor manufacturers face rising input costs as energy-intensive production becomes more expensive. EV production timelines are slipping as battery material costs surge.
Vitol CEO Russell Hardy estimated 600 to 700 million barrels of production have been lost to date, with projections reaching 1 billion barrels if the standoff continues through May. Currency markets are reacting: the Philippine peso hit a record low of 61.3 per dollar on 28 April as the import-dependent economy absorbs higher energy costs.
Adding to market uncertainty, the UAE announced on 28 April it would exit OPEC effective 1 May, citing the need for an independent review of its production capacity — a move that further fragments the ability of major producers to coordinate supply responses, reported OilPrice.com.
Europe Faces Diesel Shortage Within Weeks
While Asia bears the immediate brunt of crude shortages, Europe faces a looming diesel crisis. Refined product prices have surged even faster than crude as refining capacity cannot keep pace with demand shifts. The International Energy Agency warned that physical crude prices reaching $150 per barrel in some markets reflect genuine supply tightness, not speculative positioning. European refiners are drawing down inventories at unsustainable rates, with shortages expected within weeks if alternative supply routes are not established.
IEA Executive Director Fatih Birol told CNBC that “the $110 trillion global economy can be taken hostage by a couple of hundred men with guns across a 50-kilometer stretch of strait — it doesn’t make sense at all.” The closure has exposed the fragility of energy infrastructure concentrated in a single choke point, with no viable short-term alternatives. Existing pipelines bypassing the strait have limited spare capacity and cannot absorb the volume of disrupted flows.
What to Watch
Storage depletion timelines are critical. If Iran exhausts capacity within the Kpler-estimated 12 to 22 days, Tehran will face a choice between production shut-ins or accepting negotiation terms. Watch for any shift in Iranian rhetoric around Strait control — a signal that economic pressure is overriding strategic posturing. On the US side, monitor Fed commentary around the April CPI print due in mid-May. If headline inflation accelerates above 4.5%, Powell may be forced to acknowledge that geopolitical shocks have overridden monetary policy transmission entirely. Semiconductor and EV manufacturers will report Q2 earnings in July; guidance on input cost pressures will reveal whether the energy shock is feeding through to durable goods prices or being absorbed in margins. Finally, European diesel inventories are the canary in the coal mine — rationing measures would signal the crisis has moved from prices to physical shortages, a threshold that could force Western governments into direct diplomatic intervention.
