Crack spread is a term used on the oil industry and futures trading for the differential between the price of crude oil and petroleum products extracted from it. The spread approximates the profit margin that an oil refinery can expect to make by "cracking" the long-chain hydrocarbons of crude oil into useful shorter-chain petroleum products.

Some observations re SpaceX
"By Friday, however, the macro narratives were entirely overshadowed by the excitement of the SpaceX IPO. It’s an IPO that will go down in history for a remarkable combination of reasons—from its sheer scale ($75 billion, almost three times the previous largest IPO) and the $1.8 trillion valuation (which places it immediately, on day one, as the seventh-most-valuable US company), to challenging the traditional playbook on investor allocation, price discovery, and fast-tracked index inclusion. It has also triggered an unprecedented wave of wealth creation, from Elon Musk’s new trillionaire status to some 4,400 millionaires minted among the firm’s current and former employees. All this for a company that generates no profits, is highly valued, and carries enormous key-person risk."

Increasing upward pressure on oil prices
Oil prices rose Friday as President Donald Trump is likely to turn his attention back to the stalemated conflict with Iran after leaving a summit in China with President Xi Jinping.International benchmark Brent crude futures for July gained more than 3% to close at $109.26 a barrel. U.S. West Texas Intermediate futures for June advanced more than 4% to settle at $105.42 per barrel.Trump told Fox News that he is losing patience with Iran. “I am not going to be much more patient. They should make a deal,” the president said in an interview that aired Thursday evening.

Details regarding the "Trump phone"
As Judd Legum of Popular Information explains, on June 16, 2025, Trump’s sons Donald Jr. and Eric announced the launch of a new, gold plated, Trump smartphone, “proudly designed and built in the United States.” It would be available in August 2025 for $499. Its website urged customers to “pre-order” the phone by depositing $100 toward it. Don Jr. said the phone would be “American hardware, built in America, without the potential of…[a] backdoor into the hardware that some of our adversaries have installed in there.”And yet a disclaimer on the website said the Trumps and the Trump Organization were involved only in the branding of the phone; they had nothing to do with the design, development, manufacture, distribution, or sales of the item. As Legum notes, the idea of a superior U.S.-made phone was always a fantasy, and within two weeks the phone’s description changed from “MADE IN THE USA” to “designed with American values in mind.”The phone never shipped, and on April 6, Trump Mobile updated its terms to say the $100 deposit was not actually a deposit for a pre-order, but rather “a conditional opportunity if Trump Mobile later elects, in its sole discretion, to offer the Device for sale.” It went on to say the deposit “does not lock in pricing, promotions, service plans, taxes, fees, shipping costs, or other commercial terms” and that “[e]stimated ship dates, launch timelines, or anticipated production schedule are non-binding estimates only.”A new phone has recently gotten clearance from the Federal Communications Commission (FCC), and Trump Mobile executives say they are waiting for approval from T-Mobile, the company whose network Trump Mobile wants to use. Legum points out that T-Mobile relies on the federal government for approval for business activities, creating an enormous conflict of interest.

Undersea data cables as wartime leverage
"In a situation of active military operations, the risk of unintentional damage increases, and the longer this conflict lasts, the higher the likelihood of unintentional damage," Kotkin said. A similar incident occurred in 2024, when a commercial vessel attacked by Iran-aligned Houthis drifted in the Red Sea and severed cables with its anchor.
"It's not as though you could just switch to satellite. That's not an alternative," Mauldin said, noting that satellites rely on connections to land-based networks and are better suited for things in motion, like airplanes and ships. Low-Earth-orbit networks such as Starlink are "a boutique solution, which is not scalable to millions of users, at this time," Kotkin added.
Iran sits on the northern shore of the Strait of Hormuz and controls long stretches of the Persian Gulf and the Gulf of Oman. These waters host all the major cable routes that link Europe, Africa, the Middle East, and Asia. This geography gives Tehran physical access to infrastructure on which the world economy depends.In fact, disrupting undersea cables is a low-cost, high-impact option that can cause global disruption without a direct missile strike. A damaged cable in the Gulf can slow internet traffic from Mumbai to Frankfurt within minutes, delay international banking settlements, and degrade cloud services used by hospitals, airlines, and power grids.Significantly, it could also cripple military communications for US CENTCOM, and regional partners would be forced to rely on backup satellites with limited bandwidth.But the situation in the Middle East is such that people are not even talking about overt operations to damage the undersea cable networks on the seabed. They are apprehensive that Iran will resort to doing so openly, which it has the capacity to do, aided by its geography. This additional maritime disruption will only add to its strategic leverage against not only the Gulf countries but also America.
A few days ago, Tasnim, the IRGC’s tame mouthpiece, published what looked like a harmless technical explainer. Maps of undersea internet cables. Locations of cloud infrastructure. Landing stations in UAE, Qatar, Bahrain, Kuwait, Saudi Arabia. A polite little observation that the southern Gulf relies on these routes far more heavily than Iran does. No podium. No death to America chant. No uniformed general doing the finger wag. Just a map. Because when you have already put drones through 3 AWS data centres and an Oracle facility, you do not need to threaten anything out loud. You publish the coordinates. You let the insurance market translate for you. You let the CEOs in Abu Dhabi and Riyadh shit their expensive trousers in private. That is how grown-ups signal escalation, and it is a mode of communication that requires a functional prefrontal cortex to receive, which is why the sunburnt Big Mac wrapper in the Oval Office has completely missed it.So let me lay out who actually holds the cards in this pissing contest, because if you have been listening to the cable news lizards you could be forgiven for thinking it is the side with the aircraft carriers.It is not.Iran’s internet runs overland. Turkey to the north, the Caucasus to the northwest. If every single submarine cable in the Persian Gulf gets severed tomorrow morning, Tehran checks its email over lunch without noticing. The southern Gulf, by contrast, is a data peninsula. UAE, Saudi, Qatar, Bahrain, Kuwait. Every banking transaction, every AI cloud workload, every ride-share app, every oil trade settlement, every fucking everything gets to the rest of the world through a handful of fibre bundles running through one of the most contested bodies of water on the planet. 99 percent of international internet traffic travels over submarine cables. The Red Sea corridor is already effectively closed because the Houthis have made it a no-go zone for repair vessels. The Gulf corridor is now being mapped by the people who just put drones into Amazon’s racks. That leaves the entire southern Gulf with precisely 0 safe options for getting their data to Europe, to India, to Africa, to anywhere.And here is the kicker. The cables do not need to be bombed. They do not need missiles. They do not need a full IRGC naval sortie. They need a fishing trawler dragging an anchor in the wrong place..."

"Demand destruction" looms
In economics, demand destruction refers to a permanent or sustained decline in the demand for a certain good in response to persistent high prices or limited supply. Because of persistent high prices, consumers may decide that it is not worth purchasing as much of that good, or seek out alternatives as substitutes.
Oxford Economics has it modelled. Oil at $150 plus for four months, global inflation back at 7.7 per cent close to the 2022 peak, world GDP growth slowing to 1.4 per cent for the year. Australian recession sharpest since the early nineties. None of this is fringe analysis. This is the orthodox economic forecasting houses now openly publishing recession scenarios with a straight face.And the equity markets are still being held up by the AI fever dream. A handful of US tech billionaires playing a hyper-financialised game of chicken on multi-trillion dollar valuations underwritten by an artificial intelligence investment bubble that still has not delivered the productivity gains it promised, and is openly built on the premise of replacing every working person on the planet. When the energy shock fully filters through into demand destruction, into corporate earnings, into job losses across logistics, transport, agriculture and manufacturing, the unwind will not be gentle. Your super fund’s overweight position in Nasdaq tech is going to find out the same way it did in 2008.The convergence is the real fucking story. Energy shock plus inflation shock plus AI bubble plus a US president actively breaking the global trade system with tariffs plus a global central banking response that has run out of room. We are looking at conditions that could make 2008 look like a kindergarten scuffle. It is not impossible to talk seriously now about Great Depression two point oh. The brokers laughing that off three months ago are now on speed dial to their compliance departments.

It may cost you more to return a rental car early
"Last summer, I flew to Geneva, Switzerland, and picked up a rental car from Budget for a two-week vacation in neighboring France. More precisely, I reserved the car for 13 days and four hours, for an estimated 866 Swiss francs, worth about $1,060 at the time. I ended up returning the vehicle not just on time but a little earlier than planned — after 13 days and 30 minutes — so imagine my surprise when the final bill came to 1,545 francs. The lion’s share of the difference was in the base rental rate, so I assume I lost my discount for returning the car early. I’ve heard of car rental companies recalculating rates for returning a weeklong rental a day early, but hours? That is ridiculous."
The car rental industry is notorious for charging customers for services they do not need or sometimes never agreed to, but collecting what amounts to a $595 fee for bringing back a car a few hours early seems beyond the pale.Even more astonishingly, perhaps, is that after examining the documentation you sent me and combing through Budget’s policies, I now believe it was not even a question of hours. You could have saved $595 by returning the car just 10 minutes later than you did...“Because the vehicle was returned earlier than the 14-day period, the rental no longer qualified for the weekly promotional pricing,” Lauren Bristow, the director of marketing communications for Avis Budget Group, wrote in response to my emailed questions. “As a result, the system recalculated the rental at the applicable shorter-term rate.”And I’ll admit that Budget’s “General Conditions of Rental” (Part 12, if you’re following along) does back her up. “Because special offers and discounts often relate to specific time slots,” it reads, “you may even end up having to pay more if you bring back the vehicle early.”

Assessing geopolitical turmoil
Most Gulf countries only have water reserves to last about a week. Analysts have said that if any of these plants are struck and capacity taken out, the impact would be quick and severe and it could wipe out water to major cities in a matter of days.Power plants need desalinated water for cooling, so electricity supply would be affected. It would particularly affect healthcare and the running of hospitals, and would likely have to cause industries and businesses to shut down for as long as there was a water shortage.Water rationing would likely have to be introduced. There are concerns that this could lead to mass panic and civil unrest.

Anomalous behavior in financial markets
When U.S. Delta Force commandos slipped into Venezuelan airspace over the weekend, they did so in secrecy. And yet, in the hours before President Donald Trump gave the final order for the strike, someone bet more than $20,000 that Nicolás Maduro would be ousted as the country’s leader by the end of January.On Polymarket, the online platform that lets people wager on almost anything, an anonymous trader somewhere in the world placed a series of suspiciously well-timed bets. Using a fresh account created last month, the individual made just a few bets in the days leading up to the raid, according to The Wall Street Journal—all on the possibility of imminent regime change in Venezuela—and appeared to come away with more than $400,000.
The online wager platform Polymarket has angered some gamblers by declaring it will not settle millions of dollars’ worth of bets on a US invasion of Venezuela, arguing that the capture of the then president, Nicolás Maduro, does not qualify.Before Donald Trump’s forces seized Maduro on Saturday morning, some traders appeared to have anticipated the shock move by placing bets on “prediction markets”.
...However, at 07:04 Eastern Time (11:04 GMT) on Monday, before US markets opened for the week, the president posted on his Truth Social platform that Washington had held "VERY GOOD AND PRODUCTIVE CONVERSATIONS" with Tehran over a "COMPLETE AND TOTAL RESOLUTION" to hostilities.Immediately, stocks bounced and the price of oil dipped to as low as $84 (£63) per barrel for the benchmark US price.Observers have since scrutinised what happened in financial markets in the minutes leading up to the president's post.At 06:49 ET, traders placed 734 bets on WTI crude oil contracts on the New York Mercantile Exchange (Nymex).One minute later, that number had jumped to 2,168. That's equivalent to about $170m.The same pattern can be seen in traders buying contracts for Brent crude, the other major oil benchmark. Between 06:48 and 06:50 ET, the volume of trades rose from 20 to more than 1,650. That's about $150m in contracts.Data for previous Mondays shows that far fewer trades are normally made at that time of day.Similar trades also happened on Monday with futures contracts for the S&P 500, Euro Stoxx 50, and other markets.This means traders placed bets on the value of the largest firms listed in the US and Europe rising minutes before Trump's announcement.

Luxury ice houses
Fishermen in the Upper Midwest are being advised that it's now time to remove their ice houses from the still-frozen lakes. Those who have not been in an ice house in decades may be gobsmacked to discover that the old-fashioned "shacks" and "shanties" have in some cases been replaced by luxury accommodations.
The houses have built-in holes in the floor that allow ice fishers to drill holes in the ice and catch a big one without ever stepping outdoors...For floor plans and features, see the Ice Castle Fish Houses website. I presume the A/C (and the shower stall seen at the back of the photo) indicate that these units are designed for dual-purpose use as mobile hunting cabins.
One model, the King Castle, has an 8-by-24-foot cabin that comes with a furnace, air conditioner, stereo, kitchen, wooden cabinets, bunk beds, bay window and eight fishing holes. Some customized models have featured retractable wheels and hydraulic lifts. Prices start at $5,900, but can top out at more than $40,000...

"Daddy, what does 'petulant' mean?"
Newsweek has contacted the White House and Transport Canada, which is responsible for Canadian certification, for comment via email. The Federal Aviation Administration (FAA) declined to comment, referring questions to the White House. It is the responsibility of the FAA to certify planes in the United States. The FAA can revoke aircraft certification if it is no longer in an airworthy condition, according to its website, but it remains unclear if it can do so for economic reasons...John Gradek, who teaches aviation management at McGill University, told Newsweek that it is unprecedented for a government to cancel the certification of an aircraft for trade reasons.He said: "Such action is typically used to ground aircraft that have been deemed unsafe to operate by the regulatory bodies. This action by President Trump is purely for commercial reasons, that Gulfstream would like to reduce competition for its Gulfstream- series general aviation aircraft by eliminating Bombardier Global Express aircraft from sales in the U.S. In his zeal to further protect the U.S. aircraft market, his stated intention to decertify all Canadian-built aircraft will have a significant impact on the domestic U.S. air travel market. There are over 1,000 Canadian-built commercial passenger aircraft in operation on any given day, a not insignificant number that would severely curtail services to/from regional airports throughout the U.S."

United Airlines claims a "window seat" does not necessarily need to have a window
"In August, United and Delta Air Lines were sued by passengers in two separate but similar suits. Both airlines were accused of unfairly charging extra for some window seats without warning that there wasn't actually a window there.
United filed a motion to dismiss the case on Monday.
"The use of the word 'window' in reference to a particular seat cannot reasonably be interpreted as a promise that the seat will have an exterior window view," the airline's lawyers wrote.
"Rather, the word 'window' identifies the position of the seat—i.e., next to the wall of the main body of the aircraft," they added.
