Oil and gas prices jump after Iran and Israel attack gasfields

TrackerFF•1h ago
Some airlines are cancelling flights left and right, others are jacking up the prices. If the war keeps going on into the summer, there's going to be some very obvious consumer-facing issues. From gas prices, very expensive travel, price hikes in logistics, you name it.
derf_•1h ago
I think the timeline is much shorter than that. These oil-producing nations have not invested in a lot of storage, because they usually ship everything out immediately. Once you no longer have anywhere to put the oil, you have to start shutting down production, and it is not easy to restart. We'll be at that point in maybe another week and a half.
general1465•1h ago
Or even sooner if Iran intensifies striking of storages. The whole Gulf is starting to feel like a complete write off...
mattmaroon•1h ago
2021 all over again except now we don’t even get a new president.
solstice•1h ago
Is there anyone here with a deeper understanding of oilfield geology and engineering? Given that:

- storage facilities in the region are limited and in some cases almost full

- mature oil fields need constant water injections to pump out the remaining crude

How likely is it that stopping crude extraction (and therefore the water injections) will permanently damage the oil reservoirs?

And based on that is it possible that countries with this type of mature oil fields would consider simply dumping the excess crude that can't be stored anymore in the desert or in the Gulf of Persia?

OgsyedIE•1h ago
There is one way that production could resume, of course: a public peace that is both real and accompanied by Iranian broadcast of orders to their coastal troops to stand down.

Given the ongoing campaign to assassinate Iranian diplomats who may be willing to negotiate peace whilst leaving hardliners alive, the only question is what kind of inducements will be necessary to get them to agree?

cogman10•1h ago
I don't think anything short of the US completely cutting ties with Israel would make Iran consider backing down at this point. And even then, I expect they'll continue directly attacking Israel.
srean•39m ago
Such a change given Iran was one of the few Middle-Eastern countries to approve of the UN resolution calling for the formation of Israel.
cogman10•29m ago
Not exactly a recent change. Since the '79 revolution Iran has had a pretty hostile position against Israel and the US. A big part of that hostility was because the US and the UK overthrew their democracy to install a puppet dictator in '53.
srean•25m ago
Indeed. Having petroleum reserves is almost always a curse. Norway seems to be the only country to have escaped unmolested.
cogman10•18m ago
Having anything a rich person in the US wants is a curse. We've overthrown governments for bananas and sugar. We tried to overthrow a government for cigars.

Basically the only reason Norway escaped this curse was they were next door to the USSR and the US knew fucking around there could easily land it in the USSR potentially also taking Sweden with it.

A few critical items beyond oil are also now in short supply:

Fertilizer, which is kind of important right now since it's springtime and farmers are planting crops around the world.

Plastic, without which modern hospitals can't operate.

Aluminum.

The list goes on, this was the dumbest war in our lifetimes but it's the culmination of a lot of previous stupidity that made it all possible.

The people who started this war are authoritarians and, let's be honest, straight up criminals, who did it to entrench their grip on their own domestic politics.

cogman10•1h ago
Yes to fertilizer,

no to plastic,

IDK about aluminum.

The liquid to make plastic is a natural byproduct of oil processing. That stuff is literally cheaper than water because everyone that processes oil needs to get rid of it. Even if it triples in price, there will still be plenty of it available on the global market.

cogman10•41m ago
Right, and my point is that even if it were actually 80% of the supply offline, there's still enough production to meet global demand.

Again, the stuff is cheaper than water.

I hope we have teams in Yemen too taking advantage of the cut off of war supplies.

Argonaut998•1h ago
I’m probably missing some subtext or sarcasm here but because they don’t have ICBMs to reach the US?
srean•1h ago
Even if they could I don't think they would. It is not in their interest. Their target selection does make sense from their point of view and it has been a restrained and capability constrained tit for tat.

For now all they seem to want is to have a financially viable future as an independent country, not as anybody's vassal, not as a country for other superpowers to play games for geopolitical reasons. Essentially to control their own destiny.

That was scuttled in 1953. Their civilian aircraft was shot down without apology. Saddam Hussein was foisted against them. They pulled through 8 years of wars that saw attacks with chemical weapons to which they lost several tens of thousands lives.

If they do not like the people who have messed with them, I cannot say that their feelings are unjustified.

I am not even Iranian.

myrmidon•1h ago
To state the obvious:

1) It is not clear that the people of Iran actually want to blow up refineries in general right now, but living in an autocracy they don't have much of a choice.

2) Because there is a pretty big ocean between them and most American civilians/infrastructure (this also enabled past colonial powers to wage war very pretty cost effectively and at their convenience). I'd like to argue that the prospect of retribution on home soil is important to stem aggressive wars, but at least for medieval Europe this apparently did not work that well either.

pphysch•1h ago
The buried lede: Israel did an unprovoked attack on Pars and Iran immediately retaliated by attacking QatarEnergy, which has major LNG partnerships with US oil companies.
lokar•49m ago
And it's important to not that until that point, both the US and Israel had not been attacking any of the Iranian production and export infrastructure, only some depots (and refineries?) for domestic use.
anonymous344•1h ago

longislandguido•1h ago
Yet gas is still cheaper than it was multiple times during the Biden admin. There is a modicum of manufactured hysteria here.
lokar•45m ago
The current price for crude oil does not correctly price in either:

- things end in the next 2-3 weeks and then get back to normal

- this goes on past 6-8 weeks, and stockpiles run out

The first would argue for a modest price increase, the second a somewhat unpredictable, but very severe price increase with hard to understand second order impacts.

So, the price is some weighted version of these two, based on traders estimates of what is most likely. And of course, these estimates can change quickly as events unfold, which is why the price can move so fast, despite no immediate impact to supply "on the ground".

lolc•42m ago
Whoa hold your brush. US admin agency over wars that affect oil prices was very different in 2022 compared to 2026.
fogzen•1h ago
Good. I hope gas becomes so unaffordable the US economy collapses. Maybe they'll lose some weight and it'll improve the healthcare situation.
izzydata•42m ago
It seems highly unlikely that the US will magically have trains and more walk-able living because gas is unaffordable. Especially if it was a drastic and sudden shock of supply. Myself as much as anyone is not in favor of the reliance the US has on cars and non-renewable energy, but causing chaos is not the way to do it.
pasquinelli•36m ago
i think they're saying the situation then would be such that americans won't be able to eat so much. that might shock your sensibilities, but remember that thousands of iranian civilians have been indiscriminately murdered these last couple weeks, by america.
alexgieg•30m ago
This is an interesting point. Supposing this sudden shock happens, wouldn't American towns, counties, and the like, run to buy buses and start providing emergency bus services all around to all those suburban areas where people couldn't afford gas anymore? Or at least, this is how I imagine a sane response would be.

There'd be a shortage of buses at first, but I also suppose it'd relatively easy to adapt current North American car manufacturing plants to start manufacturing buses.

But that's just an uninformed guess. Am I too much off base in this?

throwaway2109•16m ago
So you are wishing harm on Americans? Why?
Havoc•1h ago

Hard to tell whether that’s just background noise that is just getting more airtime play thanks to Iran or whether it’s the first sign of bigger trouble.

After Israel attacked gasfields and Iran retaliated. Iran didn't start any of this.

srean•54m ago
Wish this comment could be pinned.
throwaway2109•19m ago
So in your mind, Iran is an innocent party here? History started two weeks ago?

War is terrible, and I'm not sure where the immediate call to action came from to attack Iran now, but let's not pretend they haven't been funding attacks on westerners for decades. You may think that's fine, but I do not.

srean•5m ago
Counterfactual are hard to estimate but had the US and Britain not engineered a coup in 1953 to grab their oil they might have had friendly relations with US and its allies today.

Don't discount that the US foisted Saddam Hussein and his chemical weapons on Iran's population. They lost some 20 to 30 thousand civilians to chemical weapons attacks. Yet never once counter attacked with chemical weapons.

The assassinated Khamenei even had a fatwa declaring weapons of mass destruction to be un-Islamic.

No one is innocent in this world, but I can certainly understand why Iran feels the way it does and I find it justified, in the sense had I been born there I probably would feel the same way.

Recall Iran was the only middle-eastern country that supported the UN resolution forming the state of Israel.

US interference left them with a bad taste in their mouth. No wonder they do not like the US and their partners in geopolitical resource grabs.

> After Israel attacked gasfields and Iran retaliated

That timeline is incorrect. Iran attacked nearby countries oil and gas since the 2nd day of the war. So, from the get go. (Not to mention closing the Strait of Hormuz, and attacking random oil tankers).

Israel/US started the War, Iran was the first to use oil/gas as a weapon.

https://en.wikipedia.org/wiki/Timeline_of_the_2026_Iran_war

10xDev•41m ago
It is pretty clear Iran is only going up the escalation ladder when Israel does. Even Trump blamed Israel for the escalation: https://www.bbc.com/news/articles/c8x7leknlywo
yonixw•35m ago
It is really not clear at all from the timeline. Why attack Saudi oil refinery 2 days after Israel/US attacked you?

And don't bring Trump quotes when only convenient. You yourself don't believe his already existing statements. (Me too)

srean•30m ago
The justification I have heard is that crown prince okayed and assisted with the intelligence that helped with the assassination of Khamenei.

I have no way to know how far that is true, but I won't put that beyond crown prince.

10xDev•29m ago
>Israel hit Iran's South Pars - part of the world's largest natural gas field – and Tehran retaliated by striking an energy complex in Qatar.

I believe when lying doesn't help him. It doesn't matter if it is Qatar / Saudi if it still affects the US / Israel.

igravious•57m ago
“Oil and gas prices jump after US-proxy Israel attacks Iranian gasfield infrastructure, and after Iran responds in kind after having promised to do so.”

is a headline that reflects reality and doesn't finesse the details -- I should really become a headline writer, I'm clearly better than whoever is employed by The Guardian.

At the very least it should be "Oil and gas prices jump after Israel and then Iran attack gasfields"

Putting Iran first might lead some to believe this was Iran-initiated, which of course is probably the intention.

pasquinelli•42m ago
is israel a US proxy? that's feeling a little backward right now.
pzo•54m ago
I don't get why the prices jumped so much - looks like panic and hoarding because:

- The Middle East produces roughly 30% of the world's oil

- But about 20% of total global oil consumption flows through this strait (less than 30% because of of domestic consumption and some pipelines avoiding strait)

I would understand if prices increases e.g. 50% but like more than 100% seems like a panic or manipulation

lokar•50m ago
It would make sense if there was mostly inelastic demand for 80% of current production. I'm not sure if that is the case, but it might be. There is a lot of usage with no good substitute.
tencentshill•47m ago
I had this thought as well. But oil prices are set globally on the exchanges, even oil that never leaves the US is affected.
alexgieg•37m ago
Oil demand is mostly inelastic. No matter how much or how little is produced, those who need it NEED it, so they'll compete with all others who similarly need it. The richest ones from among them get the oil first, and the poorest get nothing. The end price ends up being a function of how much oil is available versus how much the richest countries' absolutely irreducibly need for oil is versus how much wealth those countries can throw at the problem not to be left without before someone else with deeper pockets gets it.
frankharv•28m ago
I agree. Why is domestic oil linked to global oil price?

We are energy independent? Big Oil is milking US.

bethekidyouwant•23m ago
if someone wants to buy American oil for twice the price overseas then it’s not gonna go to your local gas station…
frankharv•14m ago
Surely there are some shipping expenses though? For Global Oil.

Versus the Colonial Pipeline that is prevalent on the Eastern Half of US.
