Overview

This episode of The Indicator from Planet Money presents a trio of timely economic stories, each revolving around a specific "indicator of the week." The team discusses Argentina's quest for a $20 billion US bailout, Microsoft's innovative approach to cooling power-hungry data centers, and why this holiday season could be the slowest for retail hiring since the Great Recession. The conversation is lively, informative, and interspersed with playful banter.

Key Discussion Points and Insights

1. Argentina’s $20 Billion Bailout Quest

[Starts: 02:39]

• Indicator: $20 billion — the proposed size of a US "swap line" lifeline to Argentina.
• Background:
  • President Javier Milei (a Trump ally) led Argentina with promises to tame inflation and balance the budget.
  • Recent elections in Buenos Aires province saw Milei's party lose badly, precipitating a sharp peso selloff.
  • Ongoing economic crises: plummeting peso, voter backlash to austerity, and a bribery scandal involving Milei’s sister have eroded investor confidence.
  • The Argentine Central Bank has already spent over $1 billion trying to shore up the peso.
• US Involvement:
  • US Treasury Secretary Scott Besant announced negotiations for a $20 billion currency swap — the US would lend dollars to Argentina's Central Bank, which could then buy pesos to prop up its value.
  • Despite a recent US policy shift away from foreign aid (“America First”), this move is driven in part by the Trump administration’s close relationship with Milei.
• Memorable Exchange:
  • Waylon Wong: “It’s like... throwing money down a hole.” [04:09]
  • Darian Woods: "So this is kind of a break from recent news with the US... the administration has been hostile to the idea of foreign aid. America First." [04:20]
  • Adrienne Ma: “President Trump really likes Milei. On Truth Social, he called Milei a very good friend. And he said, he will never let you down.” [04:28]
  • Darian Woods: "The American taxpayer has been Rick Rolled." [04:56]

2. A New Way to Cool Data Centers: Microfluidics

[Starts: 05:03]

• Indicator: 40% — the proportion of data center electricity used for cooling (can be up to 40%).
• The Challenge:
  • AI and remote work have massively increased demand for data centers.
  • Data centers consume large amounts of electricity, much of it for cooling — chips don’t perform well when hot.
• Microsoft's Innovation:
  • Microfluidics: Instead of traditional cooling plates, tiny channels are etched into the silicon chips to deliver coolant—like "tiny braided rivers the width of a piece of hair or like the veins of a leaf." [05:53]
  • In lab tests, microfluidics removed heat up to three times better than cold plates.
  • The announcement tanked Vertiv Holdings’ stock (a data center cooling company), which dropped 5.5% post-news.
• Potential:
  • Still experimental (“just in the lab at the moment” [06:19]), but offers promise for drastically reduced energy consumption in future data centers.
• Memorable Quotes:
  • Adrienne Ma (reacting): "Ooh, I’ve never heard that term before." [05:49]
  • Darian Woods: "Imagine tiny braided rivers... That's the way coolant might be delivered to chips in the future." [05:53]
  • Adrienne Ma: "That's some very cool news, Darian. See what I did there?" [06:48]

3. A Cold Holiday Hiring Season in Retail

[Starts: 06:48]

• Indicator: 500,000 — predicted to be fewer than 500,000 seasonal retail hires, the lowest since 2009.
• What’s Changing?
  • Staffing firm Challenger, Gray & Christmas (despite the festive name, this is coincidental [07:38]) predicts the dismal seasonal hiring based on fewer public hiring plans by companies.
  • Causes: economic uncertainty (tariffs, inflation), potential reliance on automation and current permanent staff over new hires.
  • "Companies right now are planning to do more with less during the holidays." [07:50]
• Silver Linings:
  • Some exceptions: Spirit Halloween plans to hire 50,000 seasonal workers; Bath & Body Works, 30,000.
• Memorable Exchange:
  • Darian Woods: “Ominous sign for the economy I mean.” [08:19]
  • Adrienne Ma: “So that is a lot of scented candles.” [08:45]
  • Waylon Wong (teasing): “You go for, you know, their like masculine branded scents like oak and teak and whatever, mahogany, dynamite, booch.” [09:00]
  • Adrienne Ma: “Burnt steak. I just have a scented candle called Clenched Fist.” [09:10]

You're not here to make friends. You're here to talk about the news.

[C]

Friends are incidental. They could come along as well.

[A]

Would you say friends are a positive externality to talking about the news?

Friends were the positive externality we made along the way.

It is that show where we parse the most fascinating financial numbers in the news. On today's show, Argentina needs a bailout.

[C]

A new way to cool data centers and holiday retail.

[B]

Hiring is it's not looking so festive so far. That's after the break.

[B]

Waylon Wong why don't you go first?

[A]

My indicator is $20 billion. That is the size of a lifeline the US might throw to Argentina. Argentina, as you might know, is kind of a perennial economic basket. Current President Javier Milei is a close ally of President Donald Trump and so the US Has a particular interest in helping out Argentina right now.

[B]

Could you Just recap. What sort of help does Argentina need right now?

[A]

Yeah, so the Argentine peso has been plummeting in value. Earlier this month, Buenos Aires province held elections. They were pretty important, and Milei's party lost very badly. And that sparked a sell off in the peso. Now, Milei, you might remember, came into office with really big plans. He was going to tame inflation, balance the budget. But then voters were unhappy with the austerity measures he put in. And then there's been this huge corruption scandal involving his sister who's in the government. She's been accused of taking bribes. And so all of this is taking a toll on investor confidence and the Argentine peso.

[C]

So how is the US Government going to help out?

[A]

Well, as of this recording, the two countries don't have a finalized deal, but U.S. treasury Secretary Scott Besant announced on social media that they're negotiating this $20 billion swap line. This is a kind of loan where essentially gives American dollars to the Argentine Central Bank. Argentina then uses those dollars to buy pesos.

[B]

And that would have the effect of pushing up the value of the peso.

[A]

Exactly. And the Argentine Central bank has already spent more than a billion dollars of its own money trying to prop up the currency. But with the peso still falling, it's like, you know, throwing money down a hole.

[C]

And so this is kind of a break from recent news with the US the administration has been hostile to the idea of foreign aid. America First.

[A]

Yeah. I mean, we got rid of usaid. Right. But President Trump really likes Milei. On Truth Social, he called Milei a very good friend. And he said, he will never let you down.

[B]

Never let you down. I mean, tell that to the Argentine peso.

[C]

It sounds like a Rick Row.

[B]

What are you talking about? This song? Is that what we're talking about?

[C]

The American taxpayer has been Rick Rolled.

[B]

Okay. I think, Gary, you have just nominated yourself to go next.

[C]

So I want to talk about an innovation that might help with the world's energy problems. We are in the middle of this global surge in electricity demand due to all those data centers being built for artificial intelligence and video calls and so on. And a lot of that power is used for cooling.

[B]

Right. Nobody wants an overheated computer chip. Yeah.

[C]

As we all know, our phones and laptops don't work well when they're hot. As much as 40% of the electricity used in data centers can be for cooling in some cases. That's my indicator of the week. So if you could reduce that 40% of energy used for cooling in data Centers. That is a lot of power saved. And just this week, Microsoft announced a possible way to do just that. Microfluidics.

[A]

Ooh, I've never heard that term before.

[B]

Yeah, it sounds future y.

[C]

It's kind of exciting what they're doing. So rather than having a cooling plate over the entire silicon chip, they're funneling these tiny channels of coolant into the silicon itself. So imagine tiny braided rivers the width of a piece of hair or like the veins of a leaf. That's the way the coolant might be delivered to chips in the future to stop them overheating.

[A]

So how real is this right now? Is it really happening?

[C]

It's just in the lab at the moment, but the lab results are good. Microsoft's announcement said that the company's microfluidics were up to three times better than cold plates at removing heat. And investors seem to be taking that news seriously. A company called Vertiv holdings provides cooling systems for data centers. And its stock price fell about 5.5% on the day of Microsoft's announcement. Bad news for Vertiv, but good news for running data centers more cheaply.

[B]

That's some very cool news, Darian. See what I did there? Thank you. Okay, well, that, I guess, just leaves me in my indicator of the week, which has to do with the upcoming holiday shopping season. So the indicator is 500,000. Around this time each year, big retailers start hiring tons of temporary seasonal workers to help them deal with the oncoming hordes of holiday shoppers. But a staffing firm called Challenger, Gray and Christmas, they predict that for the first time since 2009, which is just after the Great recession, for the first time since then, retailers will hire fewer than 500,000 seasonal workers. And they're basing this in part on the fact that fewer companies right now are announcing their holiday hiring plans.

[C]

Then the company name has nothing to do with Christmas itself, I'm assuming.

[B]

No, but it's like a perfect name for a holiday jobs report.

[C]

Nominative determinism, where I guess their name has determined what they're doing.

[B]

That's so fun to say. Challenger Great in Christmas says this could be a sign of uncertainty among companies who are dealing with all sorts of things right now, including tariffs and inflationary pressures. And it could also be a sign that they're planning on relying more on automation and and permanent staffers to try and get through the holidays. In short, they say that it looks like companies right now are planning to do more with less during the holidays.

[C]

Ominous sign for the economy I mean.

[B]

It'S not totally bleak. On the hiring front. There are some companies that have announced their hiring plans. For example, there is Spirit Halloween, which a lot of people know they sell Halloween stuff. And they said they'd be hiring 50,000 seasonal jobs this year. And also Bath and Body Works is looking for 30,000 seasonal jobs. So that is a lot of scented candles.

[C]

We're gonna have to buy some more scented candles. Adrian.

[B]

We are the problem.

[A]

Do you guys have a favorite Bath and Body Works scent? Are you, you know, sun ripened, raspberry, cucumber, melon. Are you? You go for, you know, their like masculine branded scents like oak and teak and whatever, mahogany, dynamite, booch.

[B]

Burnt steak. I just have a scented candle called Clenched Fist. This episode was produced by Angel Carreras and engineered by Robert Rodriguez. It was fact checked by Tyler Jones. It was edited by Cake and Cannon and the indicators are production of npr.
