Oil Hits $114 as Hormuz Blockade Deepens, ECB Warns on Inflation Spillover
Brent crude reaches four-year high on supply disruption fears, with dual US-Iran blockade cutting 13 million barrels per day from global flows and pushing emerging market inflation forecasts above 5%.
Brent crude surged to $114.66 per barrel on 30 April 2026, marking a 60% rally since the US-Israeli air campaign against Iran began on 28 February and capping the largest quarterly price increase in inflation-adjusted terms since 1988.
The rally came hours after reports that US Central Command would brief President Trump on expanded military options in Iran, reigniting fears that the dual blockade of the Strait of Hormuz—in place since 13 April—will persist indefinitely. CNBC reported that Brent spiked intraday to $126 before retreating 3.2% as traders took profit on the two-month rally. WTI crude settled at $104.99, up 77% year-over-year, according to Trading Economics.
The price action reflects a market pricing in prolonged supply disruption rather than near-term resolution. Goldman Sachs estimates that exports through the strait have fallen to just 4% of normal levels, cutting 13 million barrels per day of crude, condensates, and natural gas liquids from global flows. Cumulative supply loss now exceeds 500 million barrels, with production shut-ins peaking at 9.1 million barrels per day in April, per the US Energy Information Administration.
Blockade Economics Tighten
Trump rejected Tehran’s proposal to reopen the strait in exchange for lifting the US naval blockade, which has turned away 23 vessels since 13 April. “The blockade is somewhat more effective than the bombing,” Trump told reporters on 29 April, according to CNBC. “They are choking like a stuffed pig, and it is going to be worse for them.”
Iranian Parliamentary Speaker Mohammad Bagher Ghalibaf responded in kind: “It is impossible for others to pass through the Strait of Hormuz while we cannot,” he stated on 28 April, per NPR. The bilateral impasse has left the strait—which normally carries 25% of seaborne oil trade and 20% of global liquefied natural gas—effectively closed.
Shipping costs reflect the freeze. Very Large Crude Carrier rates hit an all-time high of $423,736 per day in early March to transport 2 million barrels from the Middle East to China, according to CNBC. Rerouting around the Cape of Good Hope adds 10-14 days to transit times and increases shipping costs by 300-400%. War insurance premiums for the strait jumped from 0.125% to between 0.2% and 0.4% of vessel value per transit before the blockade, per the 2026 Strait of Hormuz Crisis timeline.
“The oil market has moved from over-optimism to the reality of the supply disruption we are seeing in the Persian Gulf. The longer this disruption persists, the less the market can rely on inventory, and the greater the need for further demand destruction.”

Inflation Spillover Intensifies
The European Central Bank warned on 30 April that “the increase in Energy prices will keep Inflation well above 2 per cent in the near term,” revising its 2026 headline inflation projection to 2.6%—up from pre-conflict baselines. The ECB noted that “as the period of high energy prices extends, the likely impact on broader inflation through indirect and second-round effects intensifies.”
Retail fuel prices are already at two-year highs. US gasoline reached $3.99 per gallon on 30 March, with diesel hitting $5.40, according to the EIA. The agency forecasts gasoline will peak at $4.30 per gallon in April, with diesel topping $5.80. Jet fuel prices have doubled since late February, forcing rationing at some airports since early April.
Emerging Markets face sharper inflation shocks. The International Monetary Fund raised its 2026 emerging market inflation forecast from 4.8% to 5.5% in its April World Economic Outlook, while cutting growth projections by 0.3 percentage points to 3.9%. The Asian Development Bank downgraded its Asia-Pacific growth forecast from 5.1% to 4.7% due to oil price impacts alone.
| Region | 2026 Inflation Forecast | 2026 Growth Forecast |
|---|---|---|
| Eurozone | 2.6% (ECB) | — |
| Emerging Markets | 5.5% (IMF) | 3.9% (IMF) |
| Asia-Pacific | — | 4.7% (ADB) |
Demand Destruction vs. Supply Risk
Goldman Sachs flagged that global oil consumption in April may be running 3.6 million barrels per day below February levels, with weakness concentrated in jet fuel and petrochemical feedstocks. The demand softness has capped Brent’s rally below the $150 level some analysts forecast if disruptions persist through Q3.
“While we keep getting these sell-offs and it keeps seeming like we’re about to finally get that football—Lucy pulls it away—and we’re back to where we started,” said Rory Johnston, founder of Commodity Context, in an interview with CNBC. “The strait still isn’t flowing, and 13 million barrels a day of production remains shut-in.”
The EIA projects Brent will peak at $115 per barrel in Q2 2026 before easing, though that forecast predates the latest blockade escalation. The Brent-WTI spread—which peaked at $25 per barrel on 31 March and averaged $11 in March, the widest in over five years—reflects logistical bottlenecks as US crude exports surged above 6 million barrels per day to fill supply gaps, per the EIA.
The Strait of Hormuz, a 21-mile-wide chokepoint between Iran and Oman, is the world’s most critical oil transit route. Before the conflict, it carried 21 million barrels per day of crude and petroleum products—roughly 21% of global consumption. Iran has threatened to close the strait during previous crises but never fully blocked it until the dual blockade began in April 2026. The current impasse marks the first time both the US and Iran have simultaneously interdicted commercial shipping in the waterway.
What to Watch
Nuclear negotiations remain deadlocked, with Trump conditioning any blockade relief on a comprehensive denuclearisation agreement Tehran has rejected. The next inflection point is the US Central Command briefing on expanded military options, which could signal either escalation or a shift toward diplomatic leverage.
On the demand side, watch for inventory draws in the EIA’s weekly petroleum status reports. The agency forecasts a global draw of 5.1 million barrels per day in Q2 2026. If realised, that would exhaust OECD commercial stocks within 90 days at current consumption rates, forcing sharper demand destruction or a return to $140+ oil.
Central Banks face a bind: raise rates to combat energy-driven inflation or hold steady to support growth. The ECB’s 30 April statement noted “heightened uncertainty” around the inflation outlook, language that typically precedes policy pivots. Emerging market currencies—already under pressure from dollar strength and capital outflows—will signal whether markets price in a sustained energy shock or a near-term resolution.
