Lead-in: The Strait of Hormuz is not just a regular shipping lane—it is one of the most critical chokepoints in the global energy system. It handles approximately 20% of global oil supply and around 20% of liquefied natural gas (LNG) transportation daily. A prolonged disruption would not merely trigger oil price volatility; it would ripple through shipping, insurance markets, industrial production, food prices, and ultimately global economic growth.

The core insight here is that the strait does not need to be fully "closed" for supply disruptions to occur. If risk perception rises, insurers withdraw coverage, and shipowners refuse to navigate through, a de facto "closure" becomes functionally equivalent to a total blockade. While military forces may escort a few vessels, they cannot instantly restore market confidence, insurance underwriting capacity, or commercial decision-making chains.

If hostilities escalate further and extend to the region’s energy infrastructure, the world could face an energy shock more severe than the 1970s oil crisis. The real question is no longer whether the strait can reopen—but whether the global energy market can still trust it as safe.

Below is the original text:

The current White House administration seeks to convey that the Strait of Hormuz could be reopened via a single "simple military operation," or that it will "self-recover" at some unspecified future date. However, as of now, the strait remains largely closed.

If this status persists—especially if conflict expands further, with Iran destroying additional energy infrastructure across the region, and the U.S. and Israel retaliating against targets inside Iran—we may be heading toward an energy crisis unseen since the 1970s, possibly even worse.

The key point is that the Strait of Hormuz does not need to be physically sealed to halt global supply chains. Modern energy systems are not just pipelines and tankers—they are complex chains of commercial decisions: shipping schedules, insurance underwriting, port access, and inventory capacity.

When enough links in this chain fail, a "functionally closed" state produces effects identical to a complete closure.

The Strait transports roughly 20 million barrels per day of crude oil, while global daily demand stands at about 100 million barrels—meaning the strait carries approximately 20% of global oil supply. It also handles around 20% of global LNG shipments. Yet today, very few vessels are able to pass through smoothly.

It is indeed the most critical maritime chokepoint in the global energy sector, but its impact extends far beyond energy. A vast volume of petrochemicals, aluminum, and fertilizers also transit through this corridor, directly affecting industrial output, agricultural production, and food prices. Even focusing only on oil and gas, there is no more important chokepoint globally.

Since the 1970s, the Gulf region has remained the epicenter of the global energy market. Iraq, Saudi Arabia, the UAE, and Iran are all major oil producers. Most of this crude travels by tanker through this narrow passage into global markets. The Strait of Hormuz is a narrow corridor winding along Iran’s coastline.

Given this geography, disrupting shipping requires minimal cost. A few drones or a small explosive-laden boat ramming a tanker can generate significant risk. You don’t need a large-scale, protracted military campaign. Prior to the current conflict, around 100 tankers passed through the strait daily. Just one or two credible attacks could prompt insurers to pull coverage and shipping operators to deem the risk unacceptable.

Naturally, alternative routes exist. Saudi Arabia can transport limited volumes of oil via pipeline. Ironical as it may sound, Iranian oil continues to circulate. Strategic petroleum reserves have already been tapped. Sanctions on Russia and Iran have been eased—though the wisdom of such moves remains highly debated.

Yet even factoring in all these mitigating elements, analysts estimate that around 10 million barrels per day of oil supply remain disrupted—possibly even more. That represents over 10% of global supply.

For comparison, the 1973 Arab oil embargo triggered long lines at gas stations, fuel rationing, and severe inflation—impacting about 6% to 7% of global supply at the time. In both absolute terms and as a share of global demand, the disruption caused by a closed Strait of Hormuz dwarfs any shock modern economies have experienced.

Or put differently: Why can’t the navy simply issue an order to “open” the strait?

Generating risk perception requires little action—but in global shipping, risk perception determines everything.

You don’t need to completely block the Strait or stop every vessel. Merely striking a tanker every few days—or even just creating a credible threat—can cause insurers and shipping companies to conclude the risk is no longer acceptable.

With so many vessels transiting the strait, full protection is impossible. Given modern drone technology and fast, agile speedboats, instilling the impression that “any vessel could be attacked at any moment” is not particularly difficult. Once that perception takes hold, the entire route begins to seem unsafe.

You might protect a few warships, or escort a handful of merchant vessels under tight naval cover. But protecting dozens of tankers and sustaining the daily flow of global energy transport is entirely different.

And once insurance underwriting is withdrawn, the market effectively shuts down on its own.

Tankers carry extremely high-value cargo. Operators won’t send them into high-risk zones without insurance, and insurers won’t underwrite open-ended geopolitical escalation. At that stage, the decision isn’t political or military—it’s purely commercial.

Thus, even if naval escorts allow some ships to pass, they cannot resolve the core bottleneck. The Strait of Hormuz isn’t closed due to a dramatic blockade. It’s closed because insurers pull coverage, operators refuse risk, and global commerce grinds to a halt.

In short, this is not just a military issue—it’s an insurance issue, a risk management issue, and ultimately a business issue. And these systems react far faster than fleet deployments.

The reason the situation currently appears strangely calm lies partly in how the disturbance manifests: not through dramatic scenes, but through absence. Tankers don’t burn on camera—they simply stop moving. Production declines in advance, and inventories buffer the first wave of shock.

Crucially, much of the region’s energy infrastructure remains physically intact. This matters. If the strait reopens quickly and infrastructure is undamaged, energy flows could normalize within weeks or months. But as risk perception solidifies and damage accumulates, that window is rapidly closing.

A closed Strait of Hormuz represents the worst-case scenario for the global energy market. If you tell people that 20 million barrels per day—the vast majority of supply passing through the strait—will be disrupted, many expect oil prices to surge to $150 or even $200 per barrel.

Yet what’s notable now is that prices remain only slightly above $100. Historically, this is already high—but not extreme.

Analysts identify several reasons for this.

One is that the market broadly expects the crisis to end with leaders stepping back, declaring mission accomplished, and finding an exit. In other words, the market anticipates that political systems won’t tolerate a prolonged, costly conflict.

But if the situation persists, energy prices may still be far from their peak.

What we see in newspapers today—the current oil price—is essentially a daily pricing mechanism set by traders based on expectations of future developments. But at some point, physical reality will dominate.

We’re already seeing early signs of this disconnect. For example, jet fuel and heating oil prices have already risen significantly above levels typically seen when benchmark crude hovers around $100 per barrel.

This signals that physical constraints are beginning to matter.

Another reason the market seems calm is temporal lag. Actual supply disruptions in certain markets take time to materialize.

If a tanker loads crude in Iraq or Saudi Arabia, it may take two weeks to reach destination. We’re still consuming oil loaded before the crisis began.

So right now, the market is drawing down inventories and relying on oil already en route. But over time, physical shortages will become more visible—and more acute.

At that point, the gap between market expectations and physical reality will close, and prices could spike rapidly.

As physical supply disruptions catch up with market expectations, prices must rise to a level capable of genuinely breaking demand. And that’s not easy. It demands massive behavioral shifts.

If the Strait of Hormuz remains closed in the coming weeks, global oil supply effectively shrinks by about 10 million barrels per day. Prices have no choice but to rise to a level sufficient to reduce global consumption by a similar amount. It’s hard to pinpoint exactly which price level would achieve this—but it will certainly be far higher than today’s levels.

Disrupting demand is not theoretical. It means consumers and businesses are forced to seek alternatives and stop buying gasoline or burning fuel.

Consumers drive less. Trips are postponed or canceled. Airlines begin adjusting flight schedules, grounding low-margin routes that are no longer financially viable at high fuel prices.

Industries follow the same logic. Factories cut shifts, or shut down entirely. Energy-intensive facilities suspend operations because fuel costs have rendered production unprofitable.

In regions less able to absorb high oil prices, we’ve already seen early signs of such responses. Several Southeast Asian nations—including Thailand, Indonesia, and Malaysia—have announced emergency measures like mandatory remote work days, school closures, and other policies explicitly designed to reduce fuel consumption.

So the central question becomes: How high must oil prices rise before the global economy consumes about 10 million fewer barrels per day?

The last time the world faced a shock of comparable scale was the 1973 Arab oil embargo. Back then, there were more readily achievable adjustments, more quick wins in efficiency gains, and more viable alternatives. But over the past decades, many of those adjustments have already been made.

Today, oil is used in sectors where short-term alternatives are limited. Long-term, alternatives certainly exist—electric vehicles, electrified industrial processes, urban redesign. But in the short term, systemic flexibility is scarce. The only remaining tool is blunt: compress economic activity.

People switch to public transit where possible. Businesses scale back operations. Some economic output vanishes outright.

As economist James Hamilton has shown, nearly every major oil shock in the 20th century was followed by economic recession. Whether this will happen again depends on how high prices ultimately climb. But if prices must rise to eliminate roughly 10 million barrels of daily global demand, then yes—this would be a shock powerful enough to push the global economy into recession.

The global policy toolbox contains no instrument capable of offsetting a daily loss of 10 to 15 million barrels of oil supply.

If the Strait of Hormuz remains closed, no amount of reserve releases, exemptions, or temporary fixes can prevent a sharp price increase. There is no combination of policy tools that can compensate for such a massive supply disruption.

Policymakers have already deployed some of their strongest measures. The International Energy Agency announced the largest coordinated release of strategic petroleum reserves in history—around 400 million barrels.

Notably, on the day the release was announced, oil prices rose—not fell. This wasn’t because the reserves were meaningless, but because the market understood the scale mismatch. Relative to the magnitude of the disruption, these reserves remain insufficient.

In such crises, what matters isn’t the total volume in reserves—but how many barrels can actually be delivered to the market each day. Under a daily supply loss of 10 to 15 million barrels, strategic reserves might replace at most 2 to 3 million barrels per day, and only for a limited duration.

Beyond that, familiar ideas resurface—those recurring in recent energy crises. For example, suspending the Jones Act to ease fuel transport between U.S. ports; relaxing environmental or fuel standards; making incremental adjustments to refining regulations.

These measures might marginally lower pump prices by a few cents. But none can stabilize prices at the scale of this disruption.

Therefore, if the Strait of Hormuz remains closed—especially if conflict escalates into sustained physical destruction of regional energy infrastructure—the outcome is not ambiguous. You’re facing not a temporary shock or a market fluctuation.

You’re facing a full-blown energy crisis. And no policy shortcut can make it disappear.

The crucial point is that energy markets don’t just react to the start or end of war. They respond to risk perception and physical damage—both of which can persist for months, even years, after hostilities cease.

One possible outcome is that risk perception never fully dissipates. Even if the U.S. declares the operation over, Iran and Israel still hold influence. Shipping will only resume when insurers, operators, and governments collectively believe passage is truly safe.

This means that even without further attacks, persistent uncertainty could keep the Strait functionally closed. Tankers won’t return simply because of a speech or a ceasefire declaration. They’ll only come back when risk premiums vanish—and that requires confidence, not announcements.

But greater danger lies in physical damage.

If major export hubs or processing facilities are hit, retaliatory strikes on other key energy assets are likely. At that point, timelines shift from weeks to years.

We’ve seen this before. In 2019, Houthi forces attacked Saudi Arabia’s Abqaiq oil processing facility, temporarily halting 5.7 million barrels per day of capacity and triggering record-speed price spikes. Though physical damage was limited and Saudi Arabia restored output remarkably quickly, the event demonstrated just how fragile the system is—and how much worse the consequences could have been.

If attacks escalate further in the current conflict, it’s not hard to imagine millions of additional barrels of supply going offline—supplies that are currently still intact.

While partial bypass routes exist around the Strait of Hormuz, they are limited in capacity and equally vulnerable. Before the crisis, Saudi Arabia exported about 7 million barrels per day. Now, using pipelines that circumvent the strait and route to Red Sea ports—especially Yanbu—it manages to export roughly 4 to 5 million barrels per day.

But these routes aren’t immune. Over recent years, the Houthis have proven they can effectively disrupt Red Sea shipping. While sustained attacks haven’t yet occurred in this round of conflict, given their ties to Iran, the risk is clearly rising.

Then there’s Qatar. After a recent attack on one of its LNG facilities, Qatari authorities stated that repairing just 20% of the damage could take three to five years—perhaps closer to two to three years. Regardless, the timeline is measured in years, not weeks or months.

This is the critical difference.

If warfare ends cleanly, with most infrastructure intact, energy flows could recover relatively quickly. But if key facilities across the region are damaged in escalating retaliatory strikes, high prices and constrained supply will persist long after the guns fall silent.

Believing that a ceasefire alone will swiftly restore energy markets is a comforting illusion—and a dangerous one. Unfortunately, this appears to be the underlying illusion behind current strategy.
