Strait of Hormuz Closure Drives Brent Crude Surge to $112 Amid Iran War Supply Shock

The near-complete shutdown of the Strait of Hormuz has propelled Brent crude over 50% higher to around $112 per barrel, widening the gap between futures and physical oil prices as Middle East supply disruptions intensify.

The Strait of Hormuz, vital for 17 million barrels per day of global oil flows, faces near-complete closure due to the escalating Iran war now in its fourth week, sending Brent crude prices surging over 50% to approximately $112 a barrel.

This supply shock has decoupled physical crude prices from futures, with Oman crude exceeding $162 per barrel and UAE's Murban topping $145, far outpacing benchmark futures amid frantic Asian buying of US oil to fill the void.

Confirmed Supply Disruption Hits Core Export Route

President Trump issued a late Saturday threat against Iran, demanding the Strait of Hormuz remain open or face severe consequences, underscoring the immediate threat to this chokepoint that handles nearly 20% of global oil supply.

Goldman Sachs estimates 17 million barrels per day through the Persian Gulf are now affected, confirming the scale of the disruption as attacks target energy infrastructure across the region.

WTI crude ended the week below $100 near 98.10, down from the prior week's close above 99, yet remains volatile within a 94-99 range amid persistent war risks.

Physical markets reflect the true scarcity: Oman crude's jump above $162 signals refiners paying premiums for spot barrels, while futures lag due to high volatility curbing trading volume.

For crude oil specifically, this means immediate supply tightening from Gulf producers, with no de-escalation signs as the conflict enters week four.

Physical-Futures Spread Signals Real Tightness

The gap between futures and physical prices widens as actual fuel supply costs rise faster, with Brent futures at $112 but regional grades like Murban at $145+.

This divergence highlights refiners' scramble: Asian buyers have ramped US oil imports to three-year highs to replace lost Middle Eastern volumes, bypassing disrupted routes.

Confirmed fact: Brent has approached $120 twice in the past two weeks, levels not seen since 2022, driven purely by Hormuz risks rather than demand shifts.

Interpretation: Futures remain somewhat capped by volatility-induced thin trading, but physical premiums confirm barrels are scarcer than benchmarks suggest.

WTI holds a tighter range below 100, but analysts eye 100 as a key barometer; a break higher could accelerate toward 110-114 if resistance cracks.

US Policy Response Eases Short-Term Pressure

US Treasury Secretary Scott Bessent announced a one-month sanctions waiver on Iranian oil in transit until April 19, alongside considerations for another Strategic Petroleum Reserve release post-recent drawdowns.

These measures aim to temper price spikes, with speculation on Russian oil shipments and even futures market intervention, though denied by Bessent.

For crude oil markets, this injects near-term supply relief, potentially stabilizing Brent around current levels while physical tightness persists.

European investors note: Waiver delays full Iranian export bans, but Hormuz closure overrides this, keeping eurozone diesel and jet fuel costs elevated.

European and DACH Refiners Face Acute Margin Squeeze

In Europe, refineries like those in Rotterdam and the Rhine valley depend heavily on Middle East grades; Hormuz disruption forces costly shifts to Atlantic basin crudes, eroding cracks.

German industrial users, from chemicals to transport, see input costs soar, adding to ECB inflation pressures amid sticky energy components.

Swiss traders report physical premiums compressing margins, with forward diesel curves inverting as DACH heating oil demand peaks into spring.

Austrian refiners, tied to OMV's Gulf exposure, face highest risks; Brent at $112 already lifts eurozone CPI by 0.3-0.5 points quarterly, per estimates.

English-speaking investors tracking DACH should monitor TTF gas-oil spreads, as crude shock amplifies Europe's energy vulnerability post-Russia pivot.

Technical Setup Points to Volatility Ahead

WTI consolidates in a bull flag below 100 Fibonacci resistance, with RSI near overbought on daily charts signaling potential short-term upside to 110-114 on a decisive break.

Support at 90-94 holds downside risks, but broader Elliott Wave structure favors lower moves post any rally, targeting 75-80 long-term if war eases.

Brent's 70% rise from pre-war levels underscores risk premium embedding, yet failure to sustain above 100 in WTI tempers immediate spike fears.

Traders wager on range-bound action between 94-99 for WTI this week, but Monday opens carry combustible gap risk from weekend developments.

Geopolitical Risks Dominate Demand Backdrop

No OPEC+ adjustments reported this week; focus squarely on involuntary supply loss rather than voluntary cuts, distinguishing this from 2022 dynamics.

Demand holds steady absent recession signals, but US gasoline prices now threaten to offset tax refunds, per economists, amplifying consumer pressure.

Macro context: Strong dollar caps upside, yet ECB divergence grows as eurozone energy inflation reaccelerates, potentially delaying rate cuts.

Risk premium stays elevated without Hormuz reopening; one violent escalation could propel Brent toward 120-140, as some analysts warn.

Investor Positioning and Near-Term Catalysts

Speculators nervous but range-trading; large players struggle in non-normal conditions, emphasizing tight risk management.

Key watch: US SPR release details, Iran response to Trump threat, Asian import data confirming rerouting scale.

DACH lens: Higher crude lifts Uniper hedging costs, pressures VW/Audi logistics; monitor DAXX energy stocks for rotation cues.

Upside risks outweigh downside in sentiment; reversals from support likely over aggressive selling.

Outlook tilts toward contained volatility if policy offsets hold, but Hormuz remains the swing factor for crude oil latest prices.
