Deutsche Bank warns oil at $150 if Hormuz stays closed through Q3
The global economy is caught between an AI-driven boom echoing 1999 and an oil shock reminiscent of 1990, with the Strait of Hormuz closure as the fulcrum determining whether the outcome is a manageable slowdown or a full-blown crisis.
Deutsche Bank's Jim Reid frames 2026 as "1999 meets 1990" — an AI investment boom pushing equities higher while a prolonged Strait of Hormuz closure threatens to push Brent crude to $150 a barrel and tip Europe into recession.
"The key variable is the Strait of Hormuz," Reid, global head of macro and thematic research at Deutsche Bank, wrote in the bank's mid-year outlook. "If it reopens by end-June, Brent falls to $86 by Q4. If it stays closed through Q3, we're looking at $150 and a very different macro picture."
Under the base case — a reopening by late June — Brent averages $109 in Q2 before sliding to $86 by year-end and $80 in 2027, Deutsche Bank projects. Global GDP growth holds at 3% this year and 3.2% next, while inflation runs at 3.8% in 2026 before easing to 3.4%. The S&P 500 target stays at 8,000, supported by $320 in per-share earnings and a 25x multiple. But the risk skew is sharply asymmetric: a closure extending into the third quarter would push Brent near $150, cut euro-area growth to 0.5% and force the European Central Bank to hike rates even as the economy stalls.
The divergence between the two scenarios is the widest Deutsche Bank has modeled in years. In the benign case, the Federal Reserve stays on hold with a residual risk of rate hikes; in the adverse case, the ECB delivers a 50-basis-point summer increase to 2.5% while the euro zone flirts with a technical recession. "The real danger is that markets are pricing the base case while inventories are already at critical lows," Reid said.
Iranian negotiators withdrew from peace talks Monday and vowed to "completely block" the waterway, according to state media, sending Brent up 7% to $97 a barrel. That remains below the March wartime peak of $118 but well above the prewar level of around $70. The average U.S. gasoline price has climbed to $4.32 a gallon from $2.98 before the conflict began in March, according to AAA.
The International Energy Agency estimates Persian Gulf producers have slashed output by more than 14 million barrels a day — roughly 14% of prewar global supply. The U.S. has been drawing about 9 million barrels a week from the Strategic Petroleum Reserve, which is on track to hit its lowest level since 1983 next week, according to Energy Information Administration data cited by the New York Times. Shipping through the Strait of Hormuz, which normally handles about 21% of the world's oil trade, stood at just 6% of normal levels in May.
The AI Counterweight
The oil shock is hitting an economy that is simultaneously receiving a powerful stimulus from artificial intelligence investment. U.S. capital spending on data centers, software and computing equipment is running at levels that Deutsche Bank compares to the late-1990s tech boom. That has helped the U.S. economy absorb the energy shock better than most: Deutsche Bank projects 2.2% GDP growth this year, with the unemployment rate holding at 4.3%.
The problem is that AI investment is currently adding to inflation, not subtracting from it. Core PCE inflation is forecast at 3% in the fourth quarter, with headline PCE peaking near 4% before falling to 3.3% by year-end. That keeps the Federal Reserve in a holding pattern — and raises the risk that if inflation proves stickier than expected, the next move could be a rate increase rather than a cut. The U.S. fiscal deficit is running at about 6.6% of GDP, with defense spending from the Iran conflict adding upside risk to 2027.
Europe Bears the Brunt
The euro area is the most exposed to a prolonged closure. Deutsche Bank cut its 2026 euro-zone GDP forecast to 0.5% from 1.1%, with the second quarter expected to contract 0.1% and the third quarter to show zero growth — a hair's breadth from technical recession. The ECB is now expected to raise its deposit rate by 50 basis points to 2.5% this summer, a stark reversal from the hold stance markets had priced before the conflict.
Germany, the region's largest economy, is forecast to grow just 0.5% this year before recovering to 1.3% in 2027 as fiscal spending kicks in. The U.K. fares slightly better at 1% growth in 2026, supported by first-quarter inventory building, but consumer price inflation is projected at 3.2% this year and the unemployment rate is seen rising to 5.4% by late summer.
Asia's Divergent Paths
China's export machine is proving resilient, with export growth forecast at 12% and imports up 25% year-to-date, driven by raw materials and upstream inputs. AI investment, green transition spending and market share gains in emerging economies are supporting the trade story. Producer prices have swung from minus 1.9% in December to plus 2.8% in March, with the full-year average seen at 3.5%.
Japan's outlook has been rewritten by oil. GDP growth is cut to 0.7% for 2026, while core-core CPI may hit 3.5% by early 2027. The Bank of Japan is accelerating its tightening cycle, with quarterly rate hikes starting in July that would bring the policy rate to 1.75% by April 2027 — a pace that would have seemed unthinkable before the conflict.
India faces a double hit from oil and a potentially weak monsoon. Deutsche Bank cut its FY27 GDP forecast to 6.7% from 7.5%, with a further downgrade to 6.3% possible if rains disappoint. The Reserve Bank of India is expected to deliver two 25-basis-point rate increases by year-end, taking the repo rate to 5.75%.
Asset Allocation Under Two Regimes
Deutsche Bank's asset allocation reflects the base case but acknowledges the tail risk. The 10-year U.S. Treasury yield target is raised to 4.7%, with the German Bund yield at 3.2%, reflecting the Fed's hold and the ECB's rate hike. The euro is seen at $1.20 by year-end, weaker than the previous $1.25 forecast, as oil prices provide near-term support for the dollar.
Equities remain the most optimistic part of the framework. The S&P 500 target of 8,000 implies 14% earnings growth and a 25x multiple, supported by strong first-quarter results from technology, energy, materials and financials. The bank recommends overweighting U.S. and European stocks while staying neutral on emerging markets and underweight Japan. Within sectors, financials, industrials and health care are preferred, while mega-cap growth and technology are cut to neutral from overweight.
Credit markets show more stress in Europe. U.S. investment-grade and high-yield spreads are expected to widen modestly to 82 and 305 basis points respectively. European equivalents are seen at 95 and 345 basis points, with the ECB's rate hike and energy costs squeezing smaller borrowers.
The last time a supply shock of this magnitude hit global oil markets was the 1990 Gulf War, when Iraq's invasion of Kuwait removed about 4.3 million barrels a day from the market and Brent doubled to $40 a barrel within three months. The current disruption — at 14 million barrels a day — is more than three times as large, though the U.S. is now a net energy exporter and strategic reserves provide a buffer that did not exist in 1990.
"The base case is manageable," Reid said. "But the gap between base and adverse is so wide that investors need to be positioned for both. If the strait doesn't reopen by September, the macro regime changes completely."
