Oil Prices Exceed $118 Following Reports of 'Extended' Iran Blockade

Brent crude futures rose more than 6% to $118.33 per barrel on April 29, 2026, after President Donald Trump rejected Iran's latest proposal to end hostilities and told reporters the U.S. naval blockade of Iranian ports would continue until Tehran agrees to a comprehensive nuclear deal [1]. "The blockade is somewhat more effective than the bombing," Trump said. "They are choking like a stuffed pig. And it is going to be worse for them. They can't have a nuclear weapon" [2].

The price spike marks a return to levels not seen since early March, when the Strait of Hormuz first closed, and signals that two months into the worst energy supply disruption since the 1970s, markets see no resolution ahead.

The Anatomy of a Dual Blockade

The current crisis traces back to February 28, 2026, when the United States and Israel launched an air campaign against Iran, including strikes that killed Supreme Leader Ali Khamenei [3]. Iran retaliated by closing the Strait of Hormuz on March 4, deploying Revolutionary Guard forces to warn off commercial vessels, board merchant ships, and lay sea mines across the waterway [3].

Before the crisis, approximately 20 million barrels per day of crude oil, fuels, and petrochemicals transited the strait — roughly one-fifth of global seaborne oil supply [4]. That flow has been reduced to a trickle. The oil production of Kuwait, Iraq, Saudi Arabia, and the United Arab Emirates collectively dropped by 6.7 million barrels per day by March 10 and by at least 10 million barrels per day two days later, as Gulf producers lost access to export routes [5].

On April 13, after ceasefire talks collapsed, the U.S. Navy imposed a full blockade of Iranian ports, creating what analysts have termed a "dual blockade" — Iran controlling the strait, the U.S. strangling Iran's maritime access [6]. A brief ceasefire in early April brought temporary relief, with Iran opening the strait to limited traffic, but on April 18, Tehran re-closed it in response to the American naval blockade [7].

The Numbers: How Big Is the Supply Gap?

The International Energy Agency has characterized this as "the largest supply disruption in the history of the global oil market" [8]. The scale dwarfs previous crises. Crude production in the Persian Gulf region has been curtailed by at least 8 million barrels per day, with an additional 2 million bpd of condensates and natural gas liquids shut in [5]. QatarEnergy declared force majeure on all LNG exports after the strait closed [5].

The world's countermeasures have partially offset the loss but cannot close the gap. On March 11, IEA member countries unanimously agreed to release 400 million barrels from strategic petroleum reserves — the largest coordinated drawdown in the agency's 52-year history, more than double the release following Russia's invasion of Ukraine [9]. Japan alone began distributing 80 million barrels, equivalent to 15 days of domestic demand [9]. But even at maximum draw rates, SPR releases provide roughly 4.5 million bpd — less than half of what the strait normally carries [10].

Vitol CEO Russell Hardy estimated on April 21 that one billion barrels of oil production would ultimately be lost because of the war, with cumulative losses already between 600 and 700 million barrels [5].

OPEC+ Spare Capacity: Can Producers Fill the Hole?

Saudi Arabia and the UAE together held more than 4 million barrels per day of spare production capacity before the crisis [11]. But both countries' ability to export has been constrained by the same strait closure that shut in their neighbors. Even where production continues, getting crude to global markets requires alternative pipeline routes with limited capacity.

The situation grew more complicated on April 28, when the UAE announced its departure from OPEC, effective May 1 — a move driven by long-simmering disputes with Saudi Arabia over production quotas, now inflamed by the crisis [12]. The exit removes one of the cartel's few remaining "shock absorbers," as analysts at CNBC described it, leaving Riyadh with a weaker hand to discipline prices [12].

The case that markets are overreacting rests on the assumption that OPEC+ spare capacity and SPR releases could together offset the shortfall within 90 days. But the arithmetic is unfavorable: even if Saudi Arabia and Iraq maximized output and every barrel found a route to market, the combined offset from spare capacity (roughly 4 million bpd) and SPR drawdowns (roughly 4.5 million bpd) still leaves an estimated gap of 9.5 million bpd against normal strait flows [10]. Oil analysts broadly agree that "all the world's responses put together cannot fully compensate for the disruption" [10].

Historical Comparisons: 1979 and Beyond

The 2026 crisis invites comparison to previous Iranian oil shocks. During the 1979 revolution, the loss of Iranian production caused prices to rise roughly 250% over 12 months. At their peak, 1979 oil prices reached $38 per barrel nominally — equivalent to approximately $148 in today's dollars [13]. The 2008 commodity boom briefly pushed WTI to nearly $150 per barrel in nominal terms [13].

The current spike is notable for its speed. Brent rose from $74 pre-war to an intraday high of $119.50 on March 9 — a 61% increase in ten days [5]. By comparison, the 1979 crisis took months to produce a comparable percentage move. The scale of disruption is also historically unprecedented: the 1973 Arab oil embargo removed roughly 5 million bpd from the market; the current crisis has displaced more than twice that amount [8].

Foreign Policy noted that the 1970s analogies have limits: the global economy is less oil-intensive today, the U.S. is a net energy exporter, and renewable energy provides a larger share of electricity generation [14]. But those structural changes offer limited comfort when transportation fuel remains overwhelmingly petroleum-based.

Who Profits, Who Pays: Market Manipulation Concerns

Three episodes of suspicious trading activity have raised questions about whether advance knowledge of policy decisions is being used to profit from oil price swings. A Financial Times investigation found $580 million in bets on falling oil prices placed just 15 minutes before Trump's March 23 announcement postponing attacks for talks [5]. A second cluster of $950 million in bearish bets appeared on April 7, shortly before Trump announced a two-week ceasefire [5]. A third batch of 7,990 lots of Brent crude futures worth an estimated $750 million was sold 20 minutes before Iran's foreign minister announced the strait was temporarily open on April 17 [5].

Physical crude prices have diverged sharply from futures markets, with physical barrels trading near $150 — far above the futures price — as the disconnect between paper and physical markets widened [5]. This gap suggests that futures prices may understate the actual cost of securing delivered crude, and that speculative positioning is playing an outsized role in headline price movements.

Consumer Impact: From Pump Prices to Grocery Bills

The pass-through from crude oil to consumer prices has been swift. U.S. gasoline prices surged roughly 30%, with the national average reaching $4 per gallon and California prices exceeding $5 per gallon by mid-March [15]. The BLS Consumer Price Index for gasoline jumped to 328.9 in March 2026, up 18.9% year-over-year [16].

The airline industry has absorbed a severe blow. Jet fuel prices spiked 95% since the war began, and jet fuel accounts for approximately 25% of airline operating costs [17]. United Airlines warned it may cut 5% of routes over the next two quarters. American Airlines, the fifth major carrier to do so, raised checked baggage fees by $10 per item [17]. Airfares industry-wide are expected to run 5–10% above pre-crisis projections through 2026 and 2027 [17].

Shipping services including USPS, Amazon, and FedEx have imposed fuel surcharges [17]. Because diesel prices affect every product that moves by truck, the inflationary ripple extends to groceries, household goods, and online retail. As one economist told CNBC: "Anything that's put on a truck is going to cost more, from groceries to Amazon packages" [15].

Inflation and Central Bank Policy

The oil shock has put central banks in a bind. U.S. headline CPI rose from 2.4% to 3.3% year-over-year in March, driven primarily by energy costs [18]. Core PCE — the Federal Reserve's preferred inflation gauge — climbed to 3.1% in January, before the worst of the spike [18].

The Federal Reserve held rates steady at 3.65% at its March meeting and is expected to maintain that position at the April 28–29 meeting [18]. FOMC minutes revealed that "many participants pointed to the risk of inflation remaining elevated for longer than expected amid a persistent increase in oil prices" [18].

The European Central Bank also held rates unchanged in March, revising its 2026 headline inflation forecast upward to 2.6%, attributing the increase to higher energy prices from the war [19]. The ECB's baseline assumes the disruption is temporary — an assumption that looks increasingly fragile.

The IMF has cut its 2026 global growth forecast to 3.1%, down 0.2 percentage points from its previous projection, and reduced the eurozone estimate to 1.1% from 1.4% [5]. The World Bank warned that energy and fertilizer prices would drive a 16% rise in overall commodity costs during 2026 [8].

Diplomatic Deadlock and Military Options

Iran's latest proposal, relayed through Pakistani mediators during the Islamabad Talks, offered to reopen the Strait of Hormuz and end the blockade if the U.S. lifted its naval siege — but with nuclear negotiations deferred to a later stage [20]. Trump rejected the offer, insisting the blockade would remain until a nuclear agreement was "100% complete" [2].

The diplomatic impasse has left limited options. The UK and France have hosted two conferences focused on reopening the strait, producing a joint statement with 36 countries expressing "readiness to contribute to efforts to ensure safe passage" [21]. The EU explored expanding its existing naval missions — Aspides and Atalanta — or establishing a framework modeled on the Black Sea Grain Initiative. But Germany, Italy, Luxembourg, Romania, Spain, and the United Kingdom have all ruled out military involvement [21].

A Defense One analysis outlined the practical difficulties: Iran has mined the strait, positioned anti-ship missiles along its coastline, and deployed fast-attack boats — all of which would need to be neutralized before commercial shipping could safely resume [21]. Even with full military commitment, analysts estimate weeks to months before minesweeping and security operations could restore reliable transit [21].

What Comes Next

The crisis now hinges on two variables: whether Trump's calculation that economic pressure will force Iran into a comprehensive nuclear deal proves correct, and how long the global economy can absorb a 9.5 million bpd supply deficit.

If the blockade extends to 60 or 90 days, SPR stockpiles will be drawn down significantly — the 400 million barrel IEA release covers roughly 44 days at the current draw rate [9]. After that, the remaining buffers narrow further. Saudi Arabia's ability to reroute exports through the Red Sea pipeline network is constrained by capacity limits, and the UAE's OPEC exit adds uncertainty about coordinated supply responses [12].

Trump met with energy executives at the White House on April 28 to discuss "measures that could be taken to continue the blockade for months, if needed, and how to limit the effects on consumers" [2]. For consumers, airlines, and energy-importing nations, that timeline represents not a reassurance but a warning.

The market, at $118.33 per barrel, appears to agree.
