US Grants 30-Day Waiver on Iranian Oil Sales as Brent Tops $112 Amid Strait of Hormuz Closure

The US Treasury issued a temporary license allowing sales of Iranian crude already loaded on vessels, aiming to flood markets with 140 million barrels and curb prices surging past $110. Brent settled at $112.19, WTI at $98.32, as Iran keeps the Strait of Hormuz shut, handling 20% of global oil flows.

US authorities granted a 30-day waiver on Friday permitting the sale of Iranian crude and petroleum products already loaded onto vessels, a direct response to crude oil prices crossing $110 per barrel for the first time since 2022.

This general license, valid until April 19, targets supply tightness from the ongoing US-Israel conflict with Iran and the effective closure of the Strait of Hormuz.

Waiver Details and Immediate Supply Impact

The Treasury Department's license allows Iranian oil imports into the US if needed to complete existing sales or deliveries, excluding regions like Cuba, North Korea, and Crimea. Treasury Secretary Scott Bessent stated on X that this could release around 140 million barrels into global markets, primarily benefiting China, Iran's largest buyer.

Energy Secretary Chris Wright noted supplies could reach Asia in three to four days, with refined products following over six weeks. This marks the third sanctions relaxation in two weeks, following similar moves on Russian oil, as prices have risen 50% since late February strikes on Iran.

Confirmed fact: Iranian vessels loaded with crude can now sell without immediate sanctions violation. Interpretation: This acts as a short-term supply buffer, but effectiveness hinges on buyer uptake and shipping logistics amid Hormuz risks.

For crude oil specifically, this injects floating storage—estimated at tens of millions of barrels—potentially capping near-term upside. Brent May futures settled Friday at $112.19, up 3.26%, while WTI April expired at $98.32, up 2.27%; the next WTI contract at $98.23.

Strait of Hormuz Closure: Core Supply Shock

Iran's effective shutdown of the Strait of Hormuz, through which 20 million barrels per day flow (20% of global oil), remains the dominant trigger. Tehran responded to US-Israel strikes with attacks on Israel and Gulf bases, hitting key energy infrastructure.

Iraq declared force majeure on foreign-operated oilfields Friday, exacerbating the squeeze. Without Hormuz, alternative routes like pipelines are insufficient; Saudi Arabia's East-West pipeline handles only 5 million bpd max.

Market relevance: This chokes Gulf exports, pushing the risk premium to levels unseen since 2022. Analysts like Kayanat Chainwala at Kotak Securities see Brent targeting $120 short-term, $150 if conflict persists a month.

Nuvama Institutional Equities projects $110-$150 over 4-8 weeks with prolonged closure. For European investors, this means immediate pressure on imported diesel and jet fuel, critical for DACH manufacturing and aviation.

European and DACH Investor Exposure

In Europe, Brent's surge directly hikes refining margins but crushes downstream costs. German refiners like Bayernoil and Miro face 30-50% input cost jumps, passing through to industrial users in chemicals and transport.

Switzerland's trading houses, handling 20% of global oil flows, navigate shadow fleet risks around Hormuz. Austrian industry, diesel-heavy, sees inflation risks; ECB watches energy pass-through closely amid stalled rate cuts.

English-speaking investors in DACH ETFs or ETCs (e.g., Brent-linked products) face volatility; a $10 Brent rise adds 5-7% to heating oil bills in winter planning. Euro weakens vs dollar on energy import bills, amplifying crude oil pain.

Why care now: Eurozone CPI energy component could spike 10-15% MoM, forcing ECB reassessment. DACH exporters lose edge as input costs soar versus US peers with WTI exposure.

US Recession Risks from Oil Shock

Analysts peg $140 sustained Brent as the US recession trigger, with $175 almost certain to tip over. Current $112 leaves room, but 70% rise since conflict start squeezes consumers; gas nears $4/gallon.

Oxford Economics cut 2026 US GDP to 2.4% from 2.8%; BMO raised recession odds to 35-40%. Businesses delay hiring, inflation rises, Fed rate cuts fade. Oil shocks historically recessioned US; this tests resilience post-pandemic.

Worst case: Three-month Hormuz closure or infrastructure hits sustain prices. Moody's warns extensive damage keeps levels high regardless of shipping.

For crude oil, this caps demand outlook; restocking post-SPR releases rebounds prices later. Iraq force majeure adds 4-5 million bpd uncertainty atop Iran.

Market Skepticism and Limited Waiver Impact

Energy analyst Brent Erickson doubts meaningful price relief without Hormuz reopening; easing sanctions on a war foe signals depleting tools. Jones Act 60-day waiver aids US domestic shipping but peripheral.

Beyond $125, oil marketers face earnings hits, LPG subsidies balloon, LNG risks mount. First $40 rise manageable via taxes; further strains systems.

Sentiment: Bullish near-term on supply fears, but waiver tempers. Positioning shows spec longs at multi-year highs; CFTC data due Monday could confirm.

Risks: Escalation deploys more US Marines to Gulf, hitting infrastructure. Iran attacks Gulf hosts amplify.

Trading Implications and Outlook

Brent-WTI spread widens on US import hopes vs global choke. European diesel cracks at multi-year highs benefit refiners short-term, crush users.

DACH angle: Higher diesel pressures trucking, chemicals; Swiss banks flag client exposure in shadow fleets. ECB energy inflation watch delays easing.

Catalysts: Weekend Hormuz updates, Monday inventories (EIA post-waiver). Upside to $120 confirmed; downside if sales flood Asia fast.

Investors: Hedge via spreads or options; monitor SPR draw pace. Conflict duration key—beyond month, $150 real.
