Scott Bessent is besties with Rob Citrone who is one of the largest purchasers of Argentine debt. He lobbied Bessent, Bessent said "Sure!"
Sometimes it really is that simple.

I want the hype to die and the bubble to pop as much as Ed and Cory and everyone else writing about it but right now it’s just them basically recycling the same bad news and posting about it. I’d love to see some writing which looks at the factors which caused previous pops and to line them up with factors today to try and determine what’s actually coming. Clearly the market is irrational as hell right now but seemingly very little is going to change that. The closest I’ve seen to what I’m looking for is the coverage over at Notes on the Crises[0] and he also seems bewildered.
Edit: I found this piece which does look at historical bubbles/market events and tries to discuss how they plan out in terms of timing [1]

They could do the China[1] / EU[2] strategy of announcing they'll do it, but never following through with it. When your opponent has the attention span of a drunken gnat, it's a surprisingly good strategy.

See perhaps "Insurance companies aren't the main villain of the U.S. health system":
* https://www.noahpinion.blog/p/insurance-companies-arent-the-main
The margins and ROE for health insurance companies aren't that big, health providers on the other hand…
Of course that doesn't necessarily mean the insurance companies are useful:

But given the realpolitik of when Obamacare was passed, the current US system was probably the only way at the time to get to universal healthcare. The ACA barely managed to get passed after all (219–212 and 60–39):

That’s interesting, because this is another clear case of total fabrication.
I will skip the $135bn figure, produced by an influence NGO and once again counting paid leave, to focus on the more serious and important alleged $500bn loss from IRS cuts.
Firstly, the statement that “the Internal Revenue Service predicted more than $500 billion in revenue loss due to DOGE-driven cuts” is fraudulent. There was no official IRS prediction of such a loss. The Washington Post reported an anonymous short-term forecast. Its exact wording was:
“Treasury Department and IRS officials are predicting a decrease of more than 10 percent in tax receipts by the April 15 deadline compared with 2024, said the people, who spoke on the condition of anonymity to share nonpublic data. That would amount to more than $500 billion in lost federal revenue.”
So, did this happen? It did not. By April 2025, collections had risen 9.5% year over year to about $850 billion, rather than falling by more than 10%. This came after a roughly 25% reduction in the IRS workforce between January and May 2025. Over the whole of fiscal year 2025, revenue increased by 6%.
Here is a follow-up Washington Post article lamenting that DOGE unfortunately failed to lower tax revenue:
https://www.washingtonpost.com/business/2025/06/12/irs-tax-filing-seas…
Wouldn’t that make the original claim dishonest, given that it was presented without any meaningful uncertainty? Apparently this distinction is unclear…

Also quoting Krugman, from today, who no longer writes for the NYT:
"Which party is out of touch, again?
Zohran Mamdani’s victory in New York, in the face of hysterical opposition from the big money, has grabbed many of the headlines, which I understand — it’s an amazing story. And I wonder what the right-wing tech bros are thinking: If Wall Street couldn’t buy New York, can they really buy America?
I’m seeing some commentators argue that Mamdani will be a problem for Democrats, allowing Republicans to paint them as extremists who are out of touch with America. But Republicans would do that anyway. For what it’s worth, Mamdani may be on the left, but all indications are that he’s a pragmatist who will get along fine with the rest of his party.
Meanwhile, you know which party is out of touch and riddled with extremists? The G.O.P.
If you look at recent Republican campaigns and positioning, it’s striking how much energy they’re putting into issues that just don’t matter much to ordinary Americans. Republicans may be obsessed with trans athletes, but most people aren’t. Polls and yesterday’s elections suggest that rants about the menace of illegal aliens have a lot less traction with the public than G.O.P. apparatchiks imagine — and that Americans don’t like the spectacle of masked ICE agents grabbing people off the street.
And if we’re talking about extremists within the party, well, Democrats have people like Mamdani, a mild-mannered guy who says he’s a socialist but…

Sure. What difference does it make if they're 1.2b or 800m? It's still huge by any metric. The current US administration is definitely clearly working in their favour. That's part of why Detusche Bank is a yuan clearing house now.

this is sort of a clickbait title.
the actual article:
https://paulkrugman.substack.com/p/elon-musk-human-ponzi-scheme
says:
We have a term for enterprises that look successful because they keep drawing in new investors and keep drawing in new investors because they look successful. They’re called Ponzi schemes. And Elon Musk is basically a human Ponzi scheme.

>But you probably recoiled in horror reading that.
Not really. I laughed at your cartoonish notion of Europe (and the idea that the US way is somehow the only or most desirable goal).
For a more balanced understanding of US vs EU relative performance and QoL, this is a helpful, recent analysis: https://paulkrugman.substack.com/p/europe-v-america-whos-really-winnin…
If the EU just continues to slowly, deliberately continue on it's path towards tighter integrated capital markets, less reliance on US security, continuing energy build out and the growing of the EUR's share of global transactions; I think that will already be more than sufficient without the need for Europeans to "come home from their 30 year post cold war vacation." - whatever that means.

IP has subtle things going against it, which you should certainly analyze more.. eg University research teams have IP too, but no clear network effect (maybe even an anti-network effect?)
To me the overall "anti-network effect" for Big Tech looks like the metatheory Krugman proposed to explain enshittification. The initial ramp up can come from proprietary code, hiring power, regulatory capture, branding, anything really, but especially a synthesis of all these

Some of the comments there call out the lack of chip fabs and express a similar suspicion that this might be a ploy to increase fossil fuel demand.

I have been enjoying Paul Krugman's writing, now that he's free from the shackles of the New York "both sides!" Times
https://paulkrugman.substack.com/p/its-beginning-to-smell-a-lot-like
He's obviously got a political angle, but doesn't let that completely color his economic analysis.

That’s because it doesn’t make sense. From Paul Krugman:
> The document simply doesn’t hang together. Part 3 makes the case for tariffs by arguing that they won’t be inflationary because they’ll lead to a stronger dollar, reducing import prices. Part 4 then calls for an all-out effort to weaken the dollar, using emergency powers if necessary.

Worse is coming and the markets seem to be in complete denial about it.
Oil has only really maintained the ~$100/barrel price because of record SPR releases worldwide. Also, that $100 price is kinda fake because it's a future price. The spot prices got much higher. Well, that runway is coming to an end. If the Strait of Hormuz re-opened today , we'd still be facing an energy shock. Plus there's famine coming.
Now the US won't run out of oil or refined petroleum products. The uS is now a net exporter. But it's a global marekt so the prices are going to go way up. And some countries and heavily dependent on oil for electricity. They are going to face blackouts.
So even though fertilizer shortages are skewed towards the Global South, food prices too are global so they're going up too.
In 1973, the energy shock took ~6 months to manifest [1].
But I think the real problem is dynamic pricing. Inflation is insidious. People start raising prices on the expectation of rising prices, thus causing prices to rise. But so many industries now are going well beyond that by essentially colluding through AI tools (eg RealPage) to further raise prices.
I honestly don't know how this ends without a deep, long recession.

If you destroy the integrity of the professional military corps through destructive and despotic behaviour that drives out those who hold to their principles, soldiers like this are the result of Hegseth’s cultification.
Nobody should be surprised.
Hegseth thinks loyalists + AI as brains can replace decades of actual real-world experience and keeping the highest ethics and morality standards with a bunch of AI-driven baboons with stars on their shoulders.
Paul Krugman wrote a good piece about exactly this.

The US is getting less safe by the day. You can also see it on tourism data and forecasts. A lot of people don’t feel safe to travel to the US any longer.
Soccer World Cup in the US and 250th anniversary of the USA would have caused a tourism boom with past administrations. But people rather go to China instead.

See also perhaps a post from today:
> Why are these terrible things happening? At a basic level they’re happening because Republicans want them to happen. Drastic cuts in food stamps and health care programs were central planks in Project 2025, which is indeed the Trump administration’s policy platform, and were written into legislation in the One Big Beautiful Bill Act that passed last summer.
[…]
> But there’s a further problem. Passing either a SNAP bill or a revised budget would require calling the House of Representatives back into session, which would in turn make it impossible for Mike Johnson, the speaker, to keep stalling the swearing-in of Adelita Grijalva, who won a special election more than 5 weeks ago.[1] And here’s the thing: Once sworn in, Grijalva would provide the decisive signature to trigger a vote in the House to release the Epstein files.[2]
