Strait of Hormuz Crisis Pushes Brent Past $100 as Stagflation Risk Forces Central Bank Rethink
Physical crude in Europe hit record $146/barrel before futures recovered to $102, creating a policy nightmare where central banks must choose between fighting inflation and preventing recession.
Brent crude futures settled at $101.82 per barrel on 13 April 2026, up nearly 7% in a single session, as the Strait of Hormuz crisis entered its sixth week with no clear resolution despite a fragile ceasefire.
The strait — which controls roughly 20% of global petroleum flow — remains effectively closed to normal commercial traffic following the 28 February US-Israeli strikes on Iran and subsequent regional escalation. Physical crude prices in Europe tell a more extreme story than futures markets suggest. North Sea Forties crude reached an all-time high of $146.43 per barrel on 9 April, according to CNBC Africa, reflecting genuine scarcity in European markets even as futures traders bet on eventual normalisation.
The divergence between physical and futures pricing — dated Brent trades roughly $27 above June futures — signals market scepticism about near-term supply restoration. Gulf countries have collectively shut in 9.1 million barrels per day in April, per the U.S. Energy Information Administration, representing approximately 9% of global oil production. Saudi Arabia alone lost 600,000 barrels per day of production capacity and 700,000 barrels per day of East-West Pipeline throughput in the initial attacks.
The Blockade Paradox
On 13 April, the United States announced a naval blockade of all Iranian ports, despite a nominal two-week ceasefire negotiated in early April having theoretically opened a path to de-escalation. The CENTCOM statement declared enforcement would apply “impartially against vessels of all nations entering or departing Iranian ports,” according to CNN.
The blockade compounds an already dire supply picture. Karen Young, senior scholar at Columbia University’s Center on Global Energy Policy, noted the self-defeating arithmetic: “If we have a blockade, we still have the problem of a shortage in the market of about 7 million barrels of crude, 4 million barrels of product not getting out. And we just added to that by making the Iranian barrels off the market.”
“We’re probably had about a five to six week buffer. But that time period is now coming to an end, and we’re really going to feel things from here.”

Strait traffic has collapsed from approximately 150 vessels per day pre-conflict to just 4-5 ships daily, with Iran selectively approving passage. The Baltic Dirty Tanker Index — which tracks crude shipping costs — peaked at 3,737 on 27 March before falling to around 2,000 after ceasefire announcements, but remains double pre-conflict levels, data from Euronews shows.
The Stagflation Trap
The energy shock has forced a wholesale revision of central bank policy trajectories. As recently as December 2025, consensus expected the Federal Reserve to continue rate cuts through 2026. The Atlanta Fed’s market probability tracker now assigns roughly 20% odds to a rate hike in 2026 — a scenario considered inconceivable three months ago, per Centura Wealth Advisory.
The policy bind is acute: energy-driven inflation is tracking toward 3.5-4.0% in the United States, with the OECD raising its US inflation outlook to 4.2%. Retail gasoline prices are forecast to peak near $4.30 per gallon in April, while diesel exceeds $5.80 per gallon. Yet the same energy costs that fuel inflation also act as a tax on consumption, raising recession risks if policymakers tighten into a supply shock.
Commonwealth Bank forecasts the Fed will pivot to rate hikes from late 2026, with approximately 75 basis points of tightening, and expects zero rate cuts this year. The bank’s analysis, detailed in an April outlook, concludes that persistent energy inflation will override growth concerns in the Fed’s reaction function.
Market Repricing Accelerates
Equity markets have bifurcated sharply. Energy sector rotation has driven outperformance in oil majors and services firms, while consumer discretionary and industrials face margin compression from input costs. The dollar has strengthened on risk-off flows, compounding pressure on emerging market debtors facing both higher energy import bills and stronger dollar obligations.
Brent crude front-month futures finished Q1 2026 at $118 per barrel, marking the largest inflation-adjusted quarterly increase since 1988, according to EIA data. The 1970s oil shocks — when OPEC supply cuts drove stagflation across developed economies — remain the closest historical parallel, though current disruption stems from geopolitical conflict rather than cartel coordination.
Treasury markets have repriced inflation expectations aggressively. The 10-year breakeven inflation rate — derived from the spread between nominal and inflation-protected securities — has pushed above 3%, reflecting expectations that energy costs will feed through to broader price indices even if crude moderates from current levels.
The EIA’s April Short-Term Energy Outlook forecasts Brent will peak at $115 per barrel in Q2 2026 before easing below $90 by year-end, but these projections assume conflict resolution and gradual strait reopening by late April — assumptions now in doubt given the fresh US blockade and Iranian parliamentary warnings about potential toll charges on resumed traffic.
Gulf States Caught Between Powers
Saudi Arabia, the UAE, and other Gulf producers face an uncomfortable strategic position. Hesham Alghannam, a scholar at the Malcolm H Kerr Carnegie Middle East Center, wrote in Al Jazeera that “there is a quiet but palpable concern that President Trump, eager for a quick political victory, could tolerate some Iranian leverage over the strait in exchange for a fragile truce.”
Gulf energy infrastructure has absorbed significant damage that will take months to repair even under optimistic scenarios. The East-West Pipeline — critical for Saudi exports that bypass Hormuz entirely — operates at 700,000 barrels per day below capacity. Insurance costs for tankers willing to navigate Gulf waters remain elevated, creating a structural premium in shipping economics that persists regardless of formal ceasefire agreements.
- Physical-futures spread signals market expects prolonged scarcity despite official optimism about ceasefire durability
- Central Banks face impossible trade-off: tighten into recession risk or ease into persistent inflation
- Energy majors outperform as sector rotation accelerates; consumer discretionary faces margin compression
- Dollar strength via risk-off flows compounds emerging market stress from higher energy import costs
What to Watch
The gap between physical and futures pricing will narrow only when tanker traffic through Hormuz returns to pre-conflict volumes — a development requiring not just ceasefire maintenance but also Iranian willingness to facilitate passage without punitive tolls or selective approvals. Current traffic of 4-5 vessels daily represents roughly 3% of normal flow.
Central bank communications in coming weeks will reveal whether policymakers view energy inflation as transitory supply shock or persistent structural shift requiring monetary response. The Fed’s May meeting will provide the first formal policy statement since the 13 April blockade announcement.
Refinery utilisation rates in Europe and Asia will indicate whether the physical premium reflects genuine scarcity or precautionary inventory building. If run rates decline despite high margins, it would confirm supply constraints are binding rather than psychological.
Any Iranian move to formalise toll charges on strait passage — as parliamentary speakers have hinted — would establish a new baseline cost structure for Gulf crude exports, permanently elevating the floor price even after conflict resolution. The current standoff between US blockade enforcement and Iranian transit control creates a game-theoretic impasse with no obvious resolution path that doesn’t involve one side backing down entirely.
