Editor’s note: The article points out that the current global oil supply is only short by about 20%, but what truly escalates the crisis isn’t “physical shortages”—it’s a three-part chain of behavior triggered by scarcity: hoarding, speculation, and capital logic of “waiting for the other side to collapse, then buying on the cheap.”

From a 20% supply gap, to disruptions in shipping through the Strait of Hormuz, to short-term “gap-filling” via strategic reserves, substitute pipelines, and capacity mismatches—on the surface, the system still seems to be running. But on a deeper level, hoarding, speculation, and capital behavior of “waiting for collapse” are amplifying the gap itself, turning a manageable supply-and-demand issue into a potential systemic risk.

The article further notes that the way such risks are triggered doesn’t follow the intuition of “gradual deterioration.” It’s more like a bank run—before confidence breaks, everything appears stable; once key variables are confirmed (reserves run out, the gap widens, shipping cannot be restored), the market will complete repricing in an extremely short time. From the 1973 oil crisis, to the 2008 financial crisis, to the 2022 energy shock—this path is highly consistent.

Under this framework, the current market’s “calm” is actually the most alarming signal: the real economy has already seen production cuts, traffic restrictions, and supply contraction, yet asset prices are still continuing risk appetite. This divergence is, in essence, the last consensus that the “system is still effective.”

The core judgment of this article is: the problem isn’t whether oil is already enough or not. It’s that once enough people start believing it might not be enough, the system will enter contraction and repricing early. Strategic reserves can only extend the time window, but they can’t provide the answer—and that window is closing rapidly.

In mid to late April, it will become a key turning point. At that time, what the market needs to face won’t be “whether it happens,” but “when it’s confirmed.”

The following is the original text:

The world is short about 20% of its oil. In theory, everyone just tightens their belts a bit, and the economy can keep running.

But in reality, “shortage” never works that way. When a critical resource comes up short, people don’t ration rationally—they start hoarding and speculating. And those with extra supply? They will wait for you to collapse, then buy your best assets for bargain-baseline prices.

These three behaviors will magnify an originally controllable gap into a civilizational-level problem.

Hoarding, speculation, and vulture-style waiting

First comes hoarding. Once “shortage” makes the headlines, everyone will start panic-buying—not because they truly need it, but because they’re afraid. What they’re buying isn’t oil; it’s a sense of “security.” And this panic alone is enough to double the actual shortage.

Next is speculation. The moment oil becomes scarce, traders swarm in, and prices rapidly break away from fundamentals. This isn’t theory—it’s a hard law of the commodities market. In history, every energy crisis has basically unfolded along this path.

The final layer—and the cruelest layer of all—is waiting for you to fall.

Why people with oil don’t sell

The spot trading price of Oman crude oil has already reached $150 to $200 per barrel. But shortage-hit countries may still not be able to buy, because players holding dollars have already locked in supply.

Some countries, despite having ample reserves, still refuse to sell to neighboring countries.

Why? Because what they see is a bigger game: waiting for the debt crisis to erupt, waiting for social unrest, and then acquiring the world’s best assets at extremely low prices. A company worth $50 billion in normal times could, when a country is on the verge of collapse, be taken for just $5 billion—no need for a single soldier.

Berkshire Hathaway currently holds nearly $375 billion in cash, setting a historical record. This accumulation began long before this war. Over 12 straight quarters, it has net sold assets. But the key isn’t the accumulation—it’s when it acts.

What is Buffett waiting for?

This script has existed for 3,000 years

In Genesis Chapter 47, Joseph helps Pharaoh hoard grain during seven years of abundance. Then the following seven years of severe famine arrive. The Egyptians first buy grain with money; once the money runs out, they exchange livestock; and once the livestock runs out, they hand over land.

By the time the famine ends, Pharaoh essentially owns nearly all of Egypt.

No war, no violence. Only control of scarce resources—and enough patience.

The logic behind the Strait of Hormuz blockade is the same. Conquering a country by force requires hundreds of thousands of troops; but blocking a strait and waiting patiently only requires a navy and time.

Joseph—at least—was trying to save the people. But the participants running this crisis are not.

That’s also why a 20% oil shortfall is enough to bring the whole world down. The problem isn’t that “there isn’t enough oil.” The problem is—someone is hoarding, someone is trading, and someone is waiting for you to collapse.

Collapse is never something that happens slowly

Most people think economic crises unfold gradually. But the reality is the opposite. One day before Lehman Brothers filed for bankruptcy, it was still operating normally. Within 48 hours before Silicon Valley Bank shut down, it didn’t look like anything was obviously wrong.

Systemic collapse is more like a “run.” When everyone trusts the bank, it runs nearly perfectly. Once trust develops a crack, everyone withdraws funds at the same time. A bank doesn’t die slowly—it collapses instantly within 48 hours.

The current global energy market is in the same state.

Everyone is betting that Trump will solve the problem quickly, and everyone is still “believing the system is still in place.” But once that trust is broken—say, reserves begin to run out, or the International Energy Agency confirms that the gap has widened further—selling will erupt like a bank run.

Not gradual. It happens in an instant.

Five weeks—already passed

Note: The Strait of Hormuz typically carries about 20 million barrels per day of oil transport. Therefore, the roughly 18–19 million barrels per day of shipping capacity lost due to the blockade currently exceeds the global 8–11.4 million barrels per day supply gap. This discrepancy is being partially hedged, including releases from strategic petroleum reserves (SPR), substitute pipelines (such as the Saudi East-West pipeline and the UAE bypass routes), and supply from non-Hormuz oil-producing countries. But this filling is temporary.

The scale of this shock has already exceeded the 2022 Russia-Ukraine energy crisis and has even been dubbed “the most severe energy crisis in human history.”

Our view is that this description is unlikely to be exaggerated.

Strategic reserves: More time ≠ safety

Right now, only two things are supporting the market: ongoing releases of strategic oil reserves, and Trump’s policy statements plus market expectations.

Even these figures have issues: releases from strategic petroleum reserves (SPR) have a physical limit, historically around 2 million barrels per day. In other words, the ability to truly fill the gap is far lower than the headline numbers on paper.

OPEC+ has 2.5 to 3.5 million barrels per day of spare capacity in name, but these export routes themselves have to pass through the Strait of Hormuz—so this capacity is effectively trapped.

Some countries’ publicly disclosed reserve data also includes delayed deliveries and overestimated inventory. Once the buffering period ends, the supply gap will quickly widen. Reserves can only buy time; they can’t buy a solution. The market still has a time window, but that window is closing.

The market is sleepwalking

The current market state is very surreal: Israel has just suffered its most intense round of missile attacks since the start of the war, yet the stock market has barely reacted. Chemical plants across Japan, South Korea, Singapore, and Thailand have begun reducing output or even shutting down, yet the market hasn’t priced in these developments. Australia has shifted toward working from home due to fuel shortages; South Korea has implemented nationwide traffic restrictions—but stocks are still rising.

Trump says Iran is negotiating every day; Iran denies every day—yet the stock market keeps rebounding. Semiconductors are still surging, AI concepts remain hot, and quant and algorithmic trading are amplifying this optimism. But if you look closely, you’ll find that many things have already turned red—only everyone is pretending not to notice.

This divergence between market performance and the real economy won’t last long. It has never happened in history.

Cards Iran has in hand

Many people are betting that Trump will resolve the problem quickly. But first, look at where Iran stands right now.

The Islamic Revolutionary Guard Corps (IRGC) has put it plainly: “The Strait of Hormuz will not reopen because of Trump’s absurd performance. We are not conducting any negotiations, and we will not do so in the future.”

There’s also the practical issue of communication itself. Iran’s leadership currently won’t handle operational-level matters through phone calls or encrypted software—Israel has assassinated Haniyeh in Tehran before, and it has also detonated Hezbollah’s pager network. This paranoia isn’t without reason. As a result, the real communication between Tehran and Washington can only take place via intermediaries such as Oman, Iraq, and Switzerland, and each round of back-and-forth takes days.

Iran’s calculations

Iran doesn’t need to win; it only needs to last longer. The blockade is the biggest card it has, and it has already found America’s weak spot. Russia supports it, and China provides it with “humanitarian aid”—so it won’t starve.

Just the toll revenue from passage through the strait could bring in tens of billions of dollars per year. If the U.S. pulls back, or gets stuck in a long grind, Iran can continue to control the strait. Wealth that originally flowed to the Gulf monarchies would also be redirected toward Tehran.

Trump’s dilemma

Don’t attack: the petrodollar system starts to loosen.

Attack: oil prices surge further. If the war drags on, Gulf crude can’t be exported, and the funding pipeline that supports the U.S. stock market would dry up.

The real risk is this: the dollar could experience a sharp devaluation. If the petrodollar loses its anchor, all dollar-denominated assets will be repriced. And worst of all, it seems that nobody inside the White House has a clean, decisive answer to this problem.

What to watch next

The U.S. SPR weekly report. The pace at which reserves are consumed is the most direct signal. The Brent crude spot and futures curve. If there’s deep contango, it means the market is pricing in long-term shortages. Trump’s tone. The heavier the rhetoric, the worse the situation often is.

Asian factory utilization rates. Declines in chemical, automotive, and semiconductor output will be the most leading indicators. Fertilizer prices. Compared with oil prices being distorted by verbal intervention, fertilizer prices are often more honest. The IEA monthly report. If the mid-April update confirms that the buffering has already been exhausted, market confidence could break overnight.

Timeline

Based on Dallas Fed data, if the Strait of Hormuz remains closed throughout the second quarter, the U.S. annualized GDP would contract by 2.9%. Multiple institutions have also been continuously raising recession probabilities. The probabilities below all come with the premise that the blockade persists through each stage. If the strait reopens early, the later stages no longer apply.

Now → April 15: Reserves are still being released

Strategic reserves are still being deployed, and Trump is still making calls. The impact on GDP is currently limited. But if the “ultimatum” on April 6 produces no results, the supply gap will expand rapidly. Probability of global economic disorder: 20%–30%

Late April → early May: Reserves hit the floor

Countries’ strategic reserves begin to bottom out, and the IEA confirms that the gap has doubled. The real-economy shock begins to concentrate and show up: fertilizer shortages, delayed spring planting, chemical plant shutdowns, LNG tightness, and reduced industrial output across Europe. Probability: 45%–65%. This is the key turning point.

Mid-May → end of June: Real economy deteriorates further

Oil prices break through $150 to $200 per barrel. High oil prices begin to suppress all economic activity. Countries compete for supplies from Russia and India, but with limited success. Europe and Asia will enter recession first. Probability: 65%–80%

After June: Systemic collapse

No new substitute supply routes emerge. Stagflation, unemployment, and central bank dysfunction occur at the same time. If rates are raised, America’s $400 trillion debt becomes unbearable; if rates aren’t raised, inflation will run completely out of control. Food crises and social unrest follow in quick succession, and gold will most likely set a new all-time high. Probability: 80%–90%

Escalation scenario

If the U.S. directly strikes Iran’s energy infrastructure, then the probability of each stage above increases by another 20 percentage points.

The 1973 oil crisis, the 2008 Lehman moment, the 2022 Russia-Ukraine energy shock—really, the script has never changed: before the data is truly confirmed, everyone pretends not to see it; once the data is confirmed, real selling starts.

We are currently in that “before confirmation” stage. April 15 to 25 is the key window. The ultimatum is the first catalyst.

If the strait reopens, the market will gradually return to normal. If it doesn’t reopen, or if the situation continues to escalate, the market will start trading the collapse itself ahead of the collapse.

The world doesn’t need to genuinely “run out of oil” for things to go wrong. It only needs enough people to believe: this could happen.
