The closure of the Strait of Hormuz has removed an estimated 4.5 percent of the world’s energy supply from circulation, and the damage may still be growing. A key Saudi pipeline that routes oil to the Red Sea has reportedly been damaged, Qatari LNG exports through the strait have halted entirely, and roughly 12 percent of global oil supply is now trapped inside the Persian Gulf.

Standard economic models treat energy as a small budget line in GDP, suggesting a disruption of this scale would barely register. The real-world correlation between energy use and economic output tells a very different story, one that matters enormously for metals investors watching inflation risk, safe-haven demand, and the durability of the current financial regime.

The gap between what economists predict and what energy disruptions actually do to output is the central argument in a recent analysis by Kurt Cobb on Oilprice.com. His framing deserves attention from anyone holding gold, silver, or mining shares, because the mechanism he describes feeds directly into the kind of stagflationary shock that drives capital toward hard assets.

The Economist’s Blind Spot

Cobb’s argument starts with a number that looks reassuringly small. About 5.7 percent of U.S. GDP goes toward procuring and distributing energy, according to a University of Michigan factsheet he cites. A conventional economist, faced with a 10 percent decline in energy availability, would multiply 5.7 percent by 10 percent and arrive at a 0.57 percent reduction in economic activity. Barely a rounding error.

That arithmetic feels clean. It is also, Cobb argues, dangerously wrong.

The problem is that energy is not just another input like office furniture or marketing spend. It is the enabling substrate for nearly every other form of economic activity. Factories do not run without power. Trucks do not move without diesel. Hospitals do not function without electricity. When energy supply contracts, the effects cascade through the entire system in ways that a simple cost-share calculation cannot capture.

Cobb points to Australian economist Steve Keen, who he says offers a clear explanation of why mainstream models understate energy’s role. The key figure Cobb relies on comes from a separate source: the correlation between economic activity and energy use is 0.9. That is nearly perfect. It means a 10 percent reduction in energy availability is far more likely to produce something close to a 10 percent decline in output than the half-percent that the textbook approach would suggest.

For metals investors, this distinction is not academic. It determines whether the current disruption is a manageable headwind or a potential recessionary force with serious implications for inflation, interest-rate policy, and the dollar.

Counting the Losses

The math Cobb walks through is worth following. Close to 20 percent of the world’s oil supply was passing through the Strait of Hormuz daily before the closure. Some estimates now say 12 percent of global oil is prevented from leaving the Persian Gulf. Oil provides about 31.5 percent of total world energy, so losing 12 percent of oil translates to roughly 3.8 percent of the world’s energy supply gone.

Then there is natural gas. In 2024, Qatar provided 3 percent of the world’s natural gas, according to U.S. Energy Information Administration data that Cobb cites. Since natural gas supplies about 23.5 percent of global energy, losing Qatar’s LNG contribution strips out another 0.7 percent of total energy. Combined with the oil losses, the world has lost an estimated 4.5 percent of its energy supply.

As we detailed when the Strait of Hormuz closure first stripped 11 million barrels a day from global supply, the physical reality of this chokepoint is hard to overstate. There is no quick substitute for the volume that flows through it.

Some relief exists at the margins. Cobb notes that some oil cargoes from Iran have left the Persian Gulf, and Iraq may soon send cargoes as well. But these are partial offsets, not solutions. And the reported damage to a key Saudi pipeline that routes crude to the Red Sea could add to the total outage if it is not repaired quickly.

What a 0.9 Correlation Means in Practice

Apply the 0.9 correlation to a 4.5 percent energy loss and you get roughly 4 percent of global economic activity potentially subtracted for every day the strait remains closed. Cobb frames this as a figure that could rival or exceed the Great Recession, during which real U.S. GDP fell 4.3 percent over a period stretching from December 2007 through June 2009, according to Federal Reserve historical data he references.

The comparison is imperfect. The Great Recession unfolded over 18 months through a credit-system collapse. An energy shock operates through a different channel: supply destruction rather than demand implosion. But the scale is instructive. A sustained loss of 4 percent of economic activity would be severe by any measure.

The question metals investors should be asking is not whether the exact number is right. It is whether the conventional framework, the one that says this disruption barely matters, is the one policymakers and markets are using to price risk.

If it is, then the market is underpricing the shock. And if the market is underpricing the shock, gold and silver have room to reprice higher as the real economic damage becomes visible.

The Helium Problem and Taiwan’s Vulnerability

Cobb raises two downstream effects that rarely make headlines but carry real weight. About one-third of the world’s helium supply is now unavailable, he writes. Helium is not a luxury gas. It is essential for MRI machines in hospitals, semiconductor manufacturing, and certain types of welding and scientific research. A sustained shortage would create bottlenecks in industries that have no easy workaround.

Taiwan’s exposure is even more striking. Cobb cites data showing that 42 percent of Taiwan’s electricity is generated using LNG imported primarily from the Persian Gulf. Taiwan is the world’s most important node for advanced semiconductor production. A sustained energy shortfall on the island would ripple through global supply chains for chips, consumer electronics, and defense systems.

When oil surged 11 percent on Iran escalation fears, the initial market reaction focused on crude prices. The deeper risk is that an energy shock of this magnitude does not stay contained in the oil market. It migrates into manufacturing, technology, and critical infrastructure in ways that standard models do not anticipate.

Why This Matters for Gold and Silver

Energy shocks create a specific kind of macro environment that has historically been favorable for precious metals. Prices rise, output falls, and central banks face an impossible choice: tighten into a supply shock and crush the economy, or accommodate inflation and let purchasing power erode.

The Federal Reserve’s own officials have begun to acknowledge this bind. As we reported, Fed Governor Goolsbee has warned that Iran-linked inflation could push rate cuts out to 2027. That timeline, if it holds, means real rates stay elevated in nominal terms while inflation eats into purchasing power from the commodity side. It is precisely the kind of environment where gold functions not as a speculation but as a store of value.

Silver carries additional exposure through its industrial demand profile. If Taiwan’s semiconductor output is constrained by energy shortfalls, the knock-on effects on silver demand from electronics manufacturing could cut both ways: reduced industrial consumption in the short term, but intensified supply-chain anxiety that drives safe-haven buying.

The bond market is already under stress from other directions. The historic 68-month drawdown in U.S. bonds has left fixed-income portfolios bruised and investors skeptical of duration risk. An energy-driven inflation shock on top of that drawdown makes the case for hard-asset allocation harder to ignore.

The Model vs. the World

Cobb’s core point is not really about the Strait of Hormuz. It is about the way economists think about energy, and by extension, the way policymakers and markets price physical-world risk. If you treat energy as a 5.7 percent budget item, you conclude that even a large disruption is manageable. If you treat energy as the foundation on which 90 percent of economic activity depends, you reach a very different conclusion.

The difference between those two frameworks is enormous. It is the difference between a market that shrugs off the closure and one that begins to price in recession, stagflation, or worse.

  • Conventional model: 4.5% energy loss = ~0.26% GDP impact (negligible)
  • Correlation-based model: 4.5% energy loss = ~4% GDP impact (recessionary)
  • Great Recession benchmark: 4.3% real GDP decline over 18 months

The gap between those estimates is not a technical quibble. It represents a massive potential mispricing of risk across equity, bond, and commodity markets.

Wall Street’s initial instinct, as we noted in our coverage of how traders bet on a tech rebound as Iran truce hopes eased the oil shock, has been to look past the disruption toward resolution. That may prove correct if the strait reopens quickly. But every day it stays closed, the cumulative damage grows in ways that the conventional framework is not designed to measure.

What to Watch

The open questions are significant. How long does the closure persist? Can the damaged Saudi pipeline be restored? Will Iranian and Iraqi workarounds provide meaningful relief? And will policymakers in Washington and at the Fed recognize the scale of the shock before markets force them to?

For investors holding gold, silver, or mining equities, the practical takeaway is straightforward. Energy shocks of this magnitude do not resolve cleanly. They create inflationary pressure, supply-chain disruption, and policy uncertainty that can persist well beyond the headlines. Physical metals and quality miners tend to perform well in exactly this kind of environment: one where the official models say everything is fine, but the real economy says otherwise.

When the models disagree with the physical world, bet on the physical world. That is what gold is for.
