The world consumes roughly 100 million barrels of oil every day. For the past several months, a significant portion of that supply has simply not been produced. The gap is not closing. And one of the most senior executives in global energy just said so on the record.

Shell CEO Wael Sawan used the company’s Q1 2026 earnings call on May 7 to deliver one of the clearest assessments yet of where the global oil market actually stands.

What Shell CEO said about oil shortage

“The hard facts are we have dug ourselves a hole of close to a billion barrels of crude shortage at the moment, either because of locked in barrels or unproduced barrels,” Sawan said during Shell’s Q1 earnings call. “And of course, that hole is deepening every single day, so the journey back will be a long one.”

He also addressed the scale of the underlying disruption directly. “What you are seeing, in essence, is just the hard realities of taking 12% of the world’s crude off the market, and you have to be able to counter that,” Sawan told CNBC on May 7.

Those comments build on what Sawan told Bloomberg on April 28. “We are talking about roughly 900 million barrels that have not been produced in the last couple of months, and that has been replaced essentially by stock drawdown,” he said. Supply balances, he warned, are set to be “tight for the coming months, if not the next year-plus.”

The context behind the global oil market

The supply disruption stems from the Iran war that began on Feb. 28, which effectively blockaded the Strait of Hormuz, the sea lane through which approximately 20% of global oil and gas flows passed before the conflict.

The IEA called it the biggest supply disruption in history.

Goldman Sachs estimated the world has been drawing down stockpiles at 11 to 12 million barrels per day to cover the gap, according to The Motley Fool. Halliburton CEO Jeffrey Miller made similar remarks on his April 21 earnings call, estimating lost production is also trending toward a billion barrels. Brent crude rose 2.8% to $111.19 a barrel following Sawan’s remarks, Yahoo Finance reported.

Even if a peace deal were struck today, Persian Gulf supply would not return to normal overnight. It could take up to seven months to restart most shut-in wells, as they require gas or water injections to repressurize.

What the barrel shortfall means for the oil market

For oil markets, the implications of a near-billion-barrel supply shortfall are significant and compounding. When inventories fall well below historical norms, the market loses its shock absorber. Any new disruption — a production outage, a weather event, a geopolitical flare-up — hits prices harder and faster than it would in a well-supplied environment.

Sawan was specific about the early signs of demand response already emerging. Jet fuel consumption has been curtailed by around 5% in the airline industry, he said. That kind of demand destruction is the market’s mechanism for rebalancing, but it also signals that prices are already high enough to change behavior, according to CNBC.

Refining margins have also come under pressure in certain segments. Crude input costs remain supported while refined product markets adjust differently, compressing margins for refiners even in a tight supply environment. For integrated companies like Shell, however, upstream and gas operations are expected to offset some of that refining pressure, helping stabilize overall cash generation.

Shell CFO Sinead Gorman confirmed on the earnings call that excess cash will be directed to share buybacks, consistent with the company’s commitment to distribute 40% to 50% of cash flow from operations through dividends and repurchases.

Shell’s CEO delivered his most direct public warning yet about the state of global oil supply and what comes next.

What oil pressures mean for the broader economy

The economic implications of a sustained oil supply shortfall extend well beyond energy markets. Oil remains a foundational input in transportation, logistics, manufacturing, and aviation. When prices remain elevated or volatile, those costs filter through the economy in stages.

The most immediate channel is inflation. Spot oil prices surged from $71 per barrel in February to $103 in March, according to Goldman Sachs’ March 2026 U.S. Inflation playbook. Goldman warned that risks remain skewed to the upside, even as its base case sees Brent easing toward $80 per barrel by Q4 2026.

The second channel is monetary policy. Central banks typically look through short-term commodity moves, but sustained energy-driven inflation can slow the disinflation process and push back the timeline for interest rate cuts. That keeps financial conditions tighter for longer, which affects borrowing costs for businesses and consumers alike.

The third channel is consumer spending. Higher fuel and transport costs reduce disposable income, particularly for lower and middle-income households that spend a larger share of their budgets on energy-related expenses. This can gradually weigh on discretionary spending and overall demand growth. The 5% curtailment in jet fuel consumption Sawan cited is an early visible example of that adjustment beginning to play out.

Key figures from Shell’s Q1 2026 earnings and Sawan’s supply assessment:

  • Estimated crude supply shortfall: Close to 1 billion barrels, described as “deepening every single day,” according to CNBC
  • Share of global oil supply removed by Hormuz blockade: Approximately 12%, CNBC confirmed
  • Stockpile drawdown pace: 11 to 12 million barrels per day, according to Goldman Sachs estimates cited by The Motley Fool
  • Jet fuel demand curtailment: Approximately 5% in the airline industry, Shell confirmed
  • Brent crude price as of May 7: $111.19 per barrel, up 2.8%, according to Yahoo Finance
  • IEA assessment: Biggest oil supply disruption in history, according to CNBC
  • Restart timeline for shut-in Persian Gulf wells: Up to seven months after Strait reopens, according to S&P Global
  • Shell shareholder return commitment: 40% to 50% of cash flow from operations via dividends and buybacks, according to Yahoo Finance

Shell’s strategic response to the oil shortage

Shell’s actions alongside Sawan’s words tell their own story. The company confirmed a $13.6 billion acquisition of Canadian shale producer ARC Resources during the same period.

That is Shell’s largest acquisition in more than a decade. Sawan said the deal was evaluated for two years before the war began, making it a pre-planned strategic move that the current supply environment has made look well-timed. The deal is expected to generate double-digit returns and boost free cash flow per share from 2027.

The message from Shell as a whole is consistent. The company believes elevated oil prices and tight supply conditions are not a temporary disruption. They are a structural environment likely to persist well into 2027.

That view is embedded in the acquisition, the buyback commitment, and the directness of Sawan’s public commentary. For investors and policymakers tracking the oil market, that consistency is the most important signal of all.
