Estimates range from a few days to a few weeks. But is that the right question?
The Oil Mystery Question
The Wall Street Journal discusses the The Oil Mystery at the Heart of America’s Pressure Campaign on Iran
It has become a multimillion-barrel mystery at the center of the U.S.-Iran war: How long does Tehran have before it runs out of room to store the oil it can no longer export?
The answer may help determine the outcome of the conflict.
A five-week-old U.S. naval blockade has trapped much of Iran’s oil inside the Persian Gulf, forcing Tehran to pump stranded barrels into rapidly filling storage tanks and aboard a flotilla of ships nearby.
U.S. officials are betting that when Iran exhausts places to stash the oil, it will face a costly, high-risk shutdown of its oil fields, forcing Tehran to blink in negotiations over its nuclear program and the wider conflict.
The U.S. government, oil traders and private analysts, however, are divided over exactly how much time Tehran has until it reaches “tank tops,” industry parlance for running out of storage.
Estimates of Iran’s onshore capacity range widely from 57% to 90% full, meaning Tehran could hit the wall in days—or hold out for weeks. Slowly throttling wells and using idle ships as floating storage are further helping Iran stretch the clock.
Vikas Dwivedi, global energy strategist at Macquarie, estimated that Iran’s prewar oil-sales revenue contributed roughly 10% to its gross domestic product.
“So even a total loss is not a catastrophic hit to their GDP, but it is an extremely large hit to their government revenue and the budget for military spending,” said Dwivedi.
S&P Global Energy estimates onshore crude stocks are around 57% full, below the historical range for this time of year. JPMorgan puts the number at 64%, leaving the equivalent of about three weeks of exports before they are full.
On the other end of the spectrum, data provider Kpler estimates onshore tanks to be 90% full, meaning they would be exhausted by the end of the week if the blockade continues.
The wide spread in estimates reflects the opacity of Iran’s oil system. Analysts use satellite images to measure the rise and fall of floating tank roofs, estimating from the size of the shadows they cast how full they are. However, fixed-roof tanks, private storage sites and damaged infrastructure are harder to assess. Some estimates don’t include storage at domestic refineries.
Meanwhile, Tehran has been slowly throttling well production. Instead of having to cut it all at once, it is easing back output in stages, hoping to avoid the more costly step of shutting fields and later spending weeks or months bringing them back.
Iran is also actively increasing refinery production. And it is able to export a modest amount—some 200,000 barrels a day, Eurasia’s Brew estimates—overland via rail and trucks, and the Caspian Sea.
This isn’t the first time Tehran has had to mothball its energy sector to outlast Washington, raising questions about the effectiveness of the U.S. pressure campaign this time around.
For more than three years after Trump imposed sanctions on Tehran in 2019, Iranian oil exports plummeted. Production also suffered, dropping below 2 million barrels a day. However, output surged back in 2022 and reached multiyear highs earlier this year.
That track record points to limited lasting impairment from prolonged disruptions, said Kim Fustier, an oil and gas analyst at HSBC, suggesting Tehran can afford to play the long game.
The Wrong Answers
- At the end of April, Trump said that Iran had about three days before its oil pipelines risked explosion from being clogged up.
- Last week, Treasury Secretary Scott Bessent said that Iran’s oil storage had filled up and Tehran would need to shut down oil production.
The Wrong Question
While analysts debate how much time Iran has, I laugh because it’s not the right question.
“Expectations may need to be adjusted,” Fustier said. “It’s hard to imagine that a weekslong blockade is going to achieve something different than 3.5 years of little exports did.”
Give Fustier credit for the correct line of thought.
The Right Questions
- How much more inflation can Trump take?
- How much more inflation on diesel and fertilizer will farmers take before they abandon Republicans in the midterms?
- How much more graft and incompetence will the US electorate in general take?
- How much oil well damage is Iran is willing to put up just to stick it to the US?
- How much pressure from Republican Senators and Congress can Trump take?
- How much global pressure from the world can Trump take?
- What is China directly pressures trump with rare earth minerals?
Those are the right questions. No one knows the answers to them either.
Regarding point 5, the Senate bucked Trump to pass the War Powers Act limiting Trump’s ability to fight this stupid war.
The House was scheduled to do the same, but Speaker Mike Johnson cancelled the vote. The Senate and House are now on recess until early June.
That’s a symbolic vote because Trump will veto it. However, that would be a very unpopular veto because the US public is sick of this war.
Not a Matter of Iran’s Time
The key question for Iran is number four: How much oil well damage is Iran is willing to put up just to stick it to the US?
I happen to believe it’s unlimited, or nearly so.
Meanwhile, good luck with the other six questions if JPMorgan is correct in its analysis that Iran has another three weeks before it matters.
My Basic Assumption From Day One
My basic assumption at the start of this stupid war was Iran primary goal is to inflict as much pain on the US as possible.
So far, that looks like the correct analysis. Iran has not budged. If anything, Iran has added demands.
So how much more is Trump willing to put up with? Ultimately, that’s what it boils down to if my basic assumption holds.
To date, the blockade has been a miserable US failure. So when does Trump capitulate if Iran doesn’t?

Why not just give the Islamic Revolutionary Guards nuclear weapons, and they can control the Straight of Hormuz and set the oil and gas production quotas for the Gulf Arab countries. That’s what this is about, so why prolong things any longer?
I don’t know how did Viet Nam work out? Korea? Iraq? Afghanistan?
Even the Russians won WW2 but everyone else jumps on that bandwagon.
The only real question should be how long can the world last before they all collapse from lack of oil?
The US is depleting it’s reserves at a rate of 10 million barrels a day & dumping them into the market to smash down prices, that game is about to end with parabolic moves higher. Not having oil is a problem, having too much isn’t a problem at all. It is this dumb thinking that is sinking the west, first Ukraine & now Iran, both times they got their asses handed to them & the real pain haven’t even started.
You mean modern society because the world will be just fine and most likely more tribal than an African nation.
Would not be surprised if Iran has plenty of SPR like storage underground. They build missile manufacturing cities underground, so an big empty storage space should be a layup.
I drilled about 25 oil and gas wells and I cannot think of a reason why a well would be damaged if it were shut in, except in some rare cases.
I’m open to an explanation of how a well would be damaged as well. Iran has a 100 years of oil field experience. The US government 0 years evidently.
Israel has zero or that seems to be the answer to everything.
Plus 30 vessels a day seem to be steaming through the strait now that the Persian Gulf Strait Authority (PGSA) has been formally established and the application / approval / payment / IRGC-Navy escort process is sorted out.

Yes, mostly carrying Iranian oil or paying fees in Yuan.
No – Oil shutdown is a known issue. And a serious one.
And Iran’s wells are particularly susceptible to damage. They are older with older technology and not maintined well.
The thing is, it impacts the entire region, not just Iran. But Iran in the worst shape from a forced shutdown.
You should be able to find lots of articles on this.
Lots of US propaganda articles, the same articles that said Iran would collapse in 3 days. Iran has had shutdowns for 30 yrs. Iran having too much oil is a problem but the world having too little isn’t? That’s just pure stupidity, Iran can wait until the US has zero reserves & not be affected but minimally.
Mish is right. Look up “water coning”. Just because the timing has been propagandized, doesn’t mean this isn’t a real issue.
Read what I said, sure there are complexities in oil, I know this. What I’m saying is that it isn’t an issue they haven’t had many times for many years & the blockade is a lie, 99% of their oil is still moving out. I am saying this is propaganda to take away from the real issue which is oil supply & the depletion of all reserves. Put simply Iran has unlimited time & the US has a few weeks. 10 millions barrels a day is being drained from the reserves which will be at 1985 levels in a week.
The fact this is even being discussed shows desperation, if they are waiting for Iran they’ll be waiting for ever. Iran spent 47 years to get to this point, you think they can’t wait another 47 years?
It has to do with the geology. Iran’s wells are particularly susceptible to damage once they are shut in.
Nonsense, Iran will make no decisions based on oil or damage of oil wells. There oil is still flowing out, the blockade is a farce & they got ample revenues from transit fees on top. Why now after 47yrs are they talking about oil well being damaged? All propaganda, it is we that are in the shit with prices skyrocketing & oil depleting daily.
Exactly, ya right, it’s all propaganda to hide the fact they have zero options that can fulfil their wet dream of regime change. still in denial of being defeated & humiliated for the whole world to see. They want an excuse for their inaction in conceding defeat or attacking again, or the wells damage will bring Iran to the table. How sheeple fall for this nonsense is beyond me.
the people of the towel persuation will never agree to anything.
they don’t fly by the seat of their pants….they fly on magic carpets.
when they begin to land ,the shtf.💩
The Iranians are a really smart people. I seriously doubt they have not already thought this out and invented or created ways to deal with this. Obviously unlike Venezuela they are very capable of building, expanding or what have you to their oil infrastructure. I’ve read they utilize 70% of their oil production internally so most likely they can throttle down with close to zero long term effects.
Iran has another coast and railways in the direction of China.
IMHO, Iran’s economy will collapse before their storage capacity and/or thier oil wells being irreparably damaged.
Unemployment and inflation are the issues with the Iranian people. Granted the ones I know aren’t engineers and just one speck of then picture.
we will break long before the Iranian people do.
they have literal ‘skin’ in this game. were over here worried about tje price of beef.
there is no we
The US has until August to find a way out of this war as money for it will run out. If that fails by some miracle, the midterms will wreck Trump. Iran doesn’t have that long to wait

Yes, just like Cuba and Venezuela under weight of massive sanctions.
Sanctions work every time, This is why Cuba is in great shape today.

Hoping Iran will surrender?
Are you joking?
Hoping is not strategy.
Surrender = Suicide
Sorry.
But but but we have airplanes and can bomb them into the Stone Age.
Bomb them with what? Ya running out of everything, ya planes got shot down to the tune of 42, ya radars all destroyed, ya bases decimated, ya got ya ass kicked so severely ya dare not even go close to Iran. You keep smoking crack though, what a clown.
“The key question for Iran is number four: How much oil well damage is Iran is willing to put up just to stick it to the US?”
I think that is almost the right question! Not just to “stick it to the US” which implies petty motives. Capitulation represents the abandonment of sovereignty to the US/West/Israel. Iranians take great pride in their fierce independence. Which is why the US/UK coup in ’53 caused so much anti-US hatred.
That leads to the Iranian decision being one about a nearly-existential sovereignty issue versus the US decision to engage in a war of choice against an “enemy” that did not and does not threaten us. We, the US, have far greater likelihood of capitulating than they do. The outcome of this war won’t make a different to us (hurt egos/pride) but would make a huge (actual) difference to them.
The oceans’ capacities are functionally speaking unlimited
If you are Iran you dump in the sea long before voluntarily damaging your own infra
I have thought of that. Don’t think they would do it. They have not threatened that yet and Trump would probably bomb their wells if they did. but then huge spikes in oil price.
Iran has been in this situation hundreds of times, the damage thesis is all bullshit. They are just pretending they got a plan & waiting for something. The reality is the US is running out of reserves not Iranian full tanks. Iran has gone from 1 million a day to 3 million a day back to 1 million again many many times & all their oil is still getting out, there is no real blockade, it’s just a blatant lie.
So, who has a better handle on Iran’s storage issues – the Iranians or the the people who haven’t been right about anything ever?
Obviously the people who haven’t been right about anything, ever.
There luck has to change, right? Right?
Exactly! The US won the war on the 1st day. Someone needs to inform the Iranian people that they have already lost.😂
Just yesterday Trump called gas prices “peanuts” – he’s caught in his own delusion. This could go on for months. Meanwhile the world economy suffers possibly irreparable damage.
Perhaps Trump is callously trying to do something about World overpopulation.
At the least there should be a billion that are further malnourished.
This is a very real concern that doesn’t get enough attention. Lots of people will die from reduced crop yields. Trump’s pride, Hegseth’s chest-medals and Palestinian-free Palestine are apparently worth more than the undernourished of the world to our leaders.
it that a feature or a.bug to Trumps crowd?

This could be bad indeed. There is now a two-thirds chance that this year will be a strong el nino year (per NOAA) and some chance it may even be a super el nino year. This has deleterious effects on rice yields in southeast Asia and maize yields in Africa. A normal procedure to help rice and maize cope with the hot dry conditions in a strong el nino year is to apply higher amounts of fertilizer. Guess what these poor countries won’t be able to do? Apply more fertilizer. So this could be a bleak year indeed for many poor people around the world, who may either experience outright shortages or prices that they cannot afford. Trump and his administration won’t care.
Survival of the fittest!
