And it’ll take energy markets even longer.

The United States and Iran have agreed on a process that could result in the end of their armed conflict and the reopening of the Strait of Hormuz. Both countries have signed the agreement, U.S. officials told reporters, though the text itself has yet to be released.
The markets, at least, are taking the deal and the promises that the strait will reopen at face value. Benchmark oil prices are now at around $83 per barrel, down slightly from $87 Friday, when traders expected that the U.S. and Iran would soon reach a deal.
“I hereby fully authorize the toll free opening of the Strait of Hormuz, and, simultaneously herewith, authorize the immediate removal of the United States Naval blockade. Ships of the World, start your engines. Let the oil flow!” Trump posted Sunday afternoon on Truth Social.
But that will not happen immediately. No matter what the United States and Iran say, it’s shippers and insurers who will make the final determination of whether the strait is truly open.
For that they will need assurances that Iran means it when it says that vessels are free to sail through, and that it won’t try to impose tolls or force ships through specific routes. “Are the Iranians going to try and control passage?” Robin Mills, chief executive officer of Qamar Energy and non-resident fellow at the Columbia University Center on Global Energy Policy, a consulting and advisory firm in the United Arab Emirates, asked me rhetorically.
This need for evidence of good faith on both sides was a theme of my conversations about the peace deal on Monday.
“The key problem isn’t whether or not the Iranians or the U.S. says the strait is open,” oil analyst Rory Johnston told me. “It is whether shippers — ships that are trapped in the Gulf, as well as ships that are waiting to move into the Gulf — have made the determination that the strait is safe for transit.”
Though some countries were able to divert substantial flows through pipeline networks to avoid the strait, that represented a relatively small amount of Gulf oil production. Johnston has estimated that of the 20 million barrels per day of oil and products that flowed through the Strait before the war, some 13 million to 15 million barrels per day worth of production have been “shut in,” meaning that they were never extracted from the ground.
Even with a peace process underway, the Gulf oil complex won’t be fully operational until ships can first get out of the Strait of Hormuz unencumbered, then get back in to pick up oil shipments, which Johnston estimates won’t happen until the beginning of next month. Some of this is just a judgement call, one that some shippers had already made before the weekend’s announcement.
“There’s been a fairly steady stream of ships that have been exiting the strait by going dark and traveling at night,” Johnston said, “so there is already an understanding for some shipping companies and some regional states that you can transit the waterway safely.”
The number of ships chancing a transit roughly correlates with the temperature of the rhetoric between the U.S. and Iran over the past few weeks. “A total of 29 verified vessel crossings were recorded through the Strait of Hormuz between 10 and 14 June,” according to the maritime analytics service Kpler said Monday. “The data aligns with reports of progress in U.S.-Iran discussions and supports the assessment that the Strait remains operational, although traffic volumes, route transparency and directional balance have yet to return to a clearly normalised pattern.”
The volumes getting through are still far off their pre-war totals, however. In the first two weeks of June, J.P. Morgan analysts estimated Hormuz flows at just over 5 million barrels per day, although about a sixth of that was likely Iranian shipments at risk of being interceded by the U.S. blockade. While that an improvement from around 3 million barrels per day in April and March, it was still well short of the 15 million to 20 million barrels per day of crude oil and petroleum products flowing through the strait before the war began in February.
The ships that have sailed the strait have largely hugged the Omani coast, according to Eurasia Group energy analyst Greg Brew, or else going through close to the Iran side, which is directly controlled by the country’s military. Three months’ worth of shooting (and mining), however, have made the central artery a no go. “There’s no certainty as to whether there are mines, how many there are, and where they are, and that matters in terms of restoring security of transit through the main waterway,” Brew told me.
The portions of the channel that offer safe passage “are not good routes for the largest ships, especially for big container ships and the largest tankers,” Brew added. Clearing the strait will likely involve navies from outside the region, including European fleets and “potentially” China, he said, many of which have ships in the area “specifically equipped for clearing mines.”
That process is likely to be iterative, Johnston told me. “It’s not like there are mines or there are not mines across the entire area,” he said. Instead, he told me, certain widths of the strait will be judged to be mine-free, allowing for safe passage, and that width will expand over time. Brew estimated that it will take two to three weeks to complete that process.
Getting the tankers back in should give oil producers the confidence to restart operations, Johnston said. “But then the challenge becomes how much upstream infrastructure was damaged,” he said. Even if the extraction infrastructure is functional, so-called “downstream” refining infrastructure could still be down, meaning that crude oil production could recover before refined products like gasoline or petroleum liquids begin returning to their previous levels.
As for how long it will take to get back up to full production, Brew told me that will vary country by country. In the short run, Gulf oil producers can pull from existing inventories of oil, with Saudi Arabia and the United Arab Emirates, which never fully shut down production, getting back to full flows in a few weeks. Iraq and Kuwait, which had to more severely curtail production, may take a few months.
Governments and companies will eventually have to rebuild their oil and natural gas stockpiles after drawing on them extensively to keep fuel prices from spiking. Among rich nations, inventories have sunk to levels not seen since depths of the post-9/11 conflict in 2003, according to the U.S. Energy Information Administration. The United States’ Strategic Petroleum Reserve had around 415 million barrels of oil before the war began, and has since fallen to around 350 million barrels, the lowest level since 1983.
All told, Johnston told me, “well over” a billion barrels of global fuel reserves have been used up since the war began.
Refilling these inventories — or, for countries newly interested in energy security, establishing them — will be a long-run addition to demand for oil, which could keep prices from falling as sharply as they might have otherwise. “We’re probably going to have two, three years of structurally higher demand as people try to restock,” Johnston said.
But the course of the war has defied risks of prices spiking higher. “This war was the biggest supply disruption in history, and oil had a hard time staying above $100 a barrel,” Brew said. “That implies that the structural factors inside the market are more keeping prices low than pulling prices high.”

Talking with National Grid’s Matthew Satterwhite about his new report with S&P Global.
This week’s conversation is with Matthew Satterwhite, head of U.S. policy for National Grid. This week National Grid released a report in collaboration with S&P Global I found noteworthy amidst the data center backlash, asserting that building new transmission lines can potentially reduce consumer costs. I reached out asking if we could chat about how this argument leans into the fight over hyperscale infrastructure. I found our conversation illuminating and educational.
The following Q&A was lightly edited for clarity.
Why did you make this report?
It’s all focused on our customers. We’re always looking to find ways to make sure we can provide our service in the most affordable way possible, the most efficient way possible, and we always think of transmission, but it’s fallen out of favor recently. There’s so much demand with large loads, data centers, advanced manufacturing, reshoring. There’s such a need, and a lot of the debate has been focused on what we need on the generation side. We think transmission is an answer, as well.
We focused on what we have control over — since we’re in deregulated states, the only generation we’re doing is to help states reach their renewable goals. It’s a real page-turner. We really get to the core of everything.
Can we lower customer bills with transmission? This report actually showed us that’s a good investment and helps with the resource adequacy and the constraint problems we have in the Northeast. You can bring cheaper electricity in.
With respect to concerns for everyday consumers, how much do you feel like new transmission might alleviate ordinary Americans’ concerns about rising energy prices?
When you look at the demand that’s coming, the projection is that by 2035, we’ll have to add 45 gigawatts, currently. We’re on that path right now. Transmission alone isn’t going to meet that, but the question is, how do we temper that down? What do we do as National Grid to help alleviate the need for all that demand? Can we get that somewhere else rather than in the region by building generation? It's a different version of all of the above. It’s not a generation single answer or a transmission single answer. We think transmission is a big part of that.
This also allows you to bring in cleaner energy from other places. The more robust the network is, you can have energy in different places and bring that in. It replaces the need for some of the generation to be built and pays for itself by creating a cheaper return for customers adding this.
How much of the data center backlash is affecting your transmission project planning calculus? How is it changing what lines are built in the country?
We’re focused on how we can provide the cheapest service for our customers and physics. It’s science and long-term planning. We don’t have the luxury — we can’t follow, this month we’re thinking something, someone got mad, and so we’re thinking something else. We study a lot of science and physics to figure out how to build the grid.
Do you feel like the average Joe Schmoe American sees transmission as making their life less expensive and making their electricity more reliable?
I think there’s frustration and a lack of understanding about the industry overall. There’s fear of the unknown. Are data centers really driving everything that’s happening? That’s where I think, with reports like this, the benefit of it will be that people will read this and see there’s other things we can do to address the load that we need, something different than building a bunch of generation plants.
How do the question marks around whether data centers get built affect transmission planning? How much harder is the backlash making your job?
It’s a science question. Do we do a bunch of work and then nothing happens? That’s why states put their policies out. There’s multiple studies you go through with a region and with a utility. I think that’s one reason why you see states slowing down, to make sure the policy is in check so people don’t do work they don’t need to do. It’s about having the policy to make sure, if you’re studying something, you’re doing it with a purpose.
Plus more of the week’s biggest development fights.
1. Clark County, Nevada – The first data center approved on federal lands has hit a legal brick wall.
2. Jackson County, Missouri – We have yet another high-profile case of a city councilor losing their job over voting for a data center, and this one’s a doozy.
3. Utah – What’s it take for the Bureau of Land Management to approve a big transmission line for zero-emission energy generation these days? Geothermal, baby.
4. Huntsville, Alabama – You can’t even build a tiny battery storage facility in the middle of Alabama anymore.
Where temporary moratoria could happen next.
Brace yourself for more statewide data center moratoria.
So far there are only two full state-wide blocks on data center permits, in New York and Texas. At least fifteen states have moratorium legislation in the pipeline, but few if any of those bills stand a chance of becoming law in the short term. Here are five states, however, where a broad development pause may gain momentum in the next year or two — and all of them are crucial to watch this November.
If you blinked you may have missed it: New Hampshire Governor Kelly Ayotte, a Republican, said she wants to enact a statewide data center moratorium.
Ayotte first came out in support of a pause last month at a Rotary Club meeting, declaring, “It does not make any sense at all to site a data center in New Hampshire.” She also reportedly plans to include a moratorium proposal in her upcoming 2027 fiscal budget. New Hampshire’s legislative sessions occur in the first half of the year, so we won’t see action on a moratorium bill this fall. But Ayotte’s statements suggest the Granite State — which is controlled by the GOP — could pivot to a pause very soon.
New Hampshire has very few data centers. Like, almost none. Only two project fights exist in the Heatmap Pro database, both in Portsmouth, and each has been canceled amidst opposition. Ayotte’s remarks were prompted by the fight against a hyperscale project being studied in the small town of Bow at a former coal plant that closed in late 2025.
None of this should surprise anyone familiar with New England NIMBYs. A New Hampshire moratorium also makes sense given the state’s proximity to Maine, which almost had one of its own. Ayotte, who is up for re-election this year, is likely looking at the political fortunes of Governor Janet Mills and trying to avoid potholes ahead of a likely blue wave hitting her state.
This week, Arizona Attorney General Kris Mayes, a Democrat, came out in support of a statewide data center moratorium.
Mayes told Arizonans in a public statement on Monday that she wants to avoid undue strain on the electric grid and adding to the burden of water cuts led by the Trump administration. Phoenix, where opposition grows by the day, seems to be the primary reason. This shouldn’t in any way be a surprise given the backlash to these projects, which in Arizona’s case is rooted in legitimate water security concerns.
One of the first high-profile data center conflicts I ever learned about was in Arizona: Project Blue, which had to move on from the city of Tucson after officials voted it down last summer. That led Amazon to bail from the facility, though it’s still under development elsewhere on county land. Locals are deeply concerned about the water impacts.
Ordinarily an attorney general wouldn’t have any sway on legislative or executive policy, but the state is already quite receptive to restricting data center development. Governor Katie Hobbs has enacted a three-year pause on tax abatements for data centers, and in response to requests for comment on Mayes’ statement, has told media she’s working on more policies targeting the sector. Hobbs has said she will do more in the following legislative session, but it’s not clear what.
The real decisive action here is probably going to be legislation, and that will depend on the reception any moratorium finds with Republicans in the state legislature, which is typically split in this purple state. The Arizona GOP is quite pro-industry, and Mayes’ opponent in her race for re-election opposes restricting data center construction.
You really should get to know the name Cindy Holscher for the next two months.
Holscher, a state senator, won a surprise upset victory in the Democratic gubernatorial primary this year, and currently sits within a one-point margin of her Republican opponent. How’d she get the nom? By calling for a statewide data center moratorium. “It reminds me of when the automobile manufacturers had to put seatbelts into their cars,“ Holscher told MSNOW after she won the primary. “We as a people and as a state just need to make sure there are guardrails in place.”
Kansas politics are weird. The state is best known as a conservative ideological bastion that’s pro-business. Full Republican control of the Kansas government during the Obama era led to significant social services cuts most closely associated with former Governor Sam Brownback. But after that, Kansans seemed to like moderate Democratic governors, electing Laura Kelly in 2022. Kelly is now term limited out of office.
Kansas already has a colorful patchwork of local data center and renewable energy restrictions. Land use is a big deal in this agricultural behemoth. Should Holscher win in a blue wave year, she would have a mandate to enact a statewide moratorium. Still, Republicans control the legislature, and that’s unlikely to change. My major questions are, should Holscher win, would the GOP in state government listen to Holscher’s request? Or can she do this through the executive branch?
Politics nerds are obsessing over Ohio right now. There, Trump acolyte Vivek Ramaswamy is neck-and-neck in the polls for governor with a Democratic candidate who backs a “conditional” data center moratorium: Amy Acton.
What’s a conditional moratorium? It’s in the eye of the beholder, really. Technically speaking, Governor Josh Shapiro instituted a conditional moratorium in Pennsylvania, where data center projects cannot get permits unless they meet very specific standards set by the governor himself. Shapiro did it through executive action, but in this case, it’s unclear whether the moratorium will be codified through that process or through law.
Should Acton win — or if former Senator Sherrod Brown defeats sitting Senator Jon Husted in the U.S. Senate race — I anticipate major legislative action on data centers in Ohio. Republicans there have essentially permanent control of the state legislature, and they’ve historically been pro-data center. But the freakout over opposition to artificial intelligence and hyperscalers in the senate race specifically has spooked national Republicans, who think it provided the opening Brown needed to potentially win back his seat. Acton and Brown’s political fortunes appear to be wedded to one another, linked to a general angst in the American public.
Every top 5 list needs a wild card, and mine is Oklahoma.
Currently, there’s minimal risk of a data center moratorium. I might’ve had this state higher on my list had Gentner Drummond won the runoff for the GOP gubernatorial primary, given his proclivity to side with anti-renewables activists who also oppose data centers. Instead, likely future governor Mike Mazzei is running on a more moderate, Trump-friendly approach to data centers centered on maintaining industry growth while protecting ratepayers from new infrastructure costs. His opponent, Cyndi Munson, supports a one-year moratorium.
I consider Oklahoma’s odds of having a data center moratorium about equal to the chance of a statewide wind energy ban. Momentum for anti-wind legislation began in the state legislature, and I expect the same to happen with data centers. But unlike the wind industry, which has enormous power in the state, data centers are still a nascent industry. This is a place that may take about two or three years to manifest full cultural upheaval over these projects.
