Key Discussion Points & Insights

1. Geopolitical Crisis: Iran War and Global Markets

• Tension at the Strait of Hormuz:
  • President Trump has threatened military action against Iran unless it reopens a critical oil chokepoint ([00:18]).
  • Last-minute diplomatic offers were exchanged—U.S. proposed a 45-day pause for reopening; Iran demanded a permanent ceasefire, sanction relief, compensation, and new governance arrangements for the strait ([00:43]).
  • Market implications: US stock futures idle and oil remains at $110/barrel in anticipation of possible military escalation ([00:43]).

2. The Central Bank Dilemma in Crisis

• How Should Central Banks React?
  • The war has already led to rising energy prices and inflation showing up in official statistics ([05:24]-[05:34]).
  • Central bankers face a dilemma:
    • Do nothing: Risk inflation “baked into” an already vulnerable economy.
    • Raise rates: Risk stifling economic recovery after the pandemic ([05:34]).
• Pierre Wunsch’s Perspective:
  • The Iran war is taking up “95%” of his professional attention ([06:11]).
    • Quote: "95%. No, I mean, I’m also running an institution. But beyond that, when talking about monetary policy, it is of course, the major source of uncertainty." – Pierre Wunsch [06:11]
  • The main uncertainty is the crisis’s duration and severity, overshadowing even the central bank’s reaction ([06:29]).
  • Comparing this crisis to 2022 (Ukraine war and COVID aftermath):
    • Fewer supply chain bottlenecks.
    • Less initial shock to the European energy system.
    • Lower inflation, but fiscal capacity now much more limited ([07:14]).
  • Risks: If political leaders try to repeat large-scale fiscal bailouts, it could trigger fiscal downgrades for countries like Belgium ([07:14]).
  • Interest rate policy:
    • If the crisis drags beyond June, likely rate hikes are needed.
    • If it turns into a financial system crisis, the situation becomes “much more difficult to manage” ([07:14], [08:55]).
    • Quote: "If we are not at the end of it by June, we’re probably going to have to hike rates. But if it would morph in some form of financial crisis or tension in financial systems, then it truly becomes much more difficult to manage." – Pierre Wunsch [07:14]
• Balancing Act:
  • 25 basis point hikes may not shift inflation but are significant signals ([08:55]).
  • The goal is to manage inflation expectations and avoid subsidizing demand for gas/oil, which undermines the correction ([08:55]).
  • Quote: "We need some demand destruction...just giving subsidies for people to be able to keep buying gas and oil...would not be the right policy." – Pierre Wunsch [08:55]

3. Europe’s Longer-Term Challenges and Unity

• Delayed Recovery in Europe:
  • The hoped-for economic rebound may once again be postponed due to external shocks ([10:10]).
• Opportunity for Policy Refocus:
  • The crisis (like Ukraine) may prompt Europe to revisit energy strategy and the need for strategic autonomy ([10:10]).
  • Balance is needed between climate goals (green agenda) and energy security ([10:10]).
  • The shock serves as a rallying point: "Europe is to be united confronted with these shocks." – Pierre Wunsch [10:10]
• ECB Governing Board Mood:
  • Resilience and resolve have been built through recent crises ([11:18]).
  • Quote: “The spirit is one of, we’ve been confronted already with so many crises over the last few years. Broadly speaking, we’ve done what we should do. We were back at our target of 2%. So we’ll have to do it again.” – Pierre Wunsch [11:18]

Markets hold their breath ahead of President Trump's looming deadline to take out Iran unless it reopens the Strait of Hormuz. Plus, how should central bankers respond to the ripple effects of the war?

[Pierre Wunsch]

We'll ask one if we are not at the end of it by June, we're probably going to have to hike rates. But if it would morph in some form of financial crisis or tension in financial systems, then it really becomes much more difficult to manage.

[Luke Vargas]

And Bill Ackman makes a play for the world's largest music company. It's Tuesday, April 7th. I'm Luke Vargas for the Wall Street Journal, and here is the AM edition of what's news, the top headlines and business stories moving your world Today, Iran and the US Are rejecting each other's diplomatic offers just hours ahead of President Trump's deadline to start bombing Iran's bridges and power plants unless it opens the Strait of Hormuz. We report that Iran has rejected a proposal from Washington that would have seen a 45 day pause in fighting in exchange for reopening the strait, saying that it wanted a permanent ceasefire, the lifting of sanctions, cut compensation for war damages and a new arrangement for governing the strait going forward. In response, President Trump said that Iran's proposal was not good enough, but it's a significant step. US Stock futures are flat and oil prices are hovering around $110 a barrel ahead of this evening's deadline. US health insurance stocks are rallying off hours after the Trump administration said it would boost 2027 Medicare Advantage payments by almost 2 and a. That dramatic increase, which represents about $13 billion in additional payments to insurers, comes after an earlier proposal to hold payments flat drew fierce criticism from the industry and torpedoed shares back in January. While the move signals strong federal support for the private insurer program, officials are proposing to eliminate a lucrative billing practice by requiring that diagnoses be linked to specific medical services, a new rule that's meant to prevent insurers from receiving payments for medical char reviews that lack an associated doctor visit. Samsung is forecasting a more than Eightfold jump in its Q1 operating profit as demand for its AI chip soars. Journal tech reporter Ji Young Sohn says it's a major reversal of fortune for Samsung, who just over a year ago had simultaneously yet to make a splash with its specialized HBM memory chips used in data centers and was seeing its more conventional chips pile up on shelves.

[Instagram Representative]

A year ago, these conventional memory chips were in a demand slump, but today they're in a massive shortage, mostly because demand has bounced back for data servers that are now needed to support all the AI models that are being used today. So AI has basically put Samsung in a very good position. They're continuing to see strong demand for hbm, while prices of conventional memory chips are surging exponentially. As a result, Samsung shares are performing very well. They're up more than 60% since the start of the year, and that's even even as markets have remained volatile due to the Middle east conflict.

[Luke Vargas]

Meanwhile, fellow South Korean consumer electronics giant LG is forecasting a Q1 earnings rebound, with profitability slated to improve as it beefs up production in the US to avoid tariffs.

the mug in the gray Bill Ackman's Pershing Square Capital is offering to buy Universal Music Group, whose roster includes the likes of Taylor Swift heard there, Kendrick Lamar and Billie Eilish. Pershing Square said the transaction, which would involve a new entity listing on the New York Stock Exchange, is expected to close by year's end. Universal didn't immediately respond to a request for comment. The deal would value the company at around $60 billion and its stock is soaring on news of the offer and Amazon and the US Postal Service have made a deal after threatening a 2/3 pullback in the OF packages that it ships through the usps. We exclusively report that a tentative agreement will lead to just a 20% reduction in volume. If approved, the deal would avoid a major revenue drop for the struggling post office and avoid delivery headaches for Amazon, especially in rural areas.

or disrupted shipping still months off, we are already seeing higher inflation cropping up in official statistics. So how should a central banker react? Do nothing well, you risk higher prices being baked into an economy still scarred by the pandemic or raise rates and risk sapping economies of their growth potential. One central banker facing just such a decision later this month when he'll vote on the European Central Bank's next rate move is Pierre Wunsch, the government of the national bank of Belgium. Governor, thank you so much for being with us on what's news.

[Pierre Wunsch]

Pleasure.

[Interviewer]

How much is the war in Iran dominating your attention these days?

[Pierre Wunsch]

95%. No, I mean, I'm also running an institution. But beyond that, when talking about monetary policy, it is of course, the major source of uncertainty. And I would say our reaction function is probably of second order in terms of uncertainty compared to the uncertainty in just the length and the depth of the crisis, of which.

[Interviewer]

Are you more certain now than you were, say, a week ago?

[Pierre Wunsch]

Not really. I mean, we listen to the communications coming from the US and also the reactions from Iran. It's not easy to read. And like the markets, we get signals, I would say, every day in one or the other direction and of course, the length of the crisis. You were of course referring to the fact that typically for a central banker, a supply shock, an energy shock is one of the most difficult to deal with. And of course, last time we were a little bit late, you know, team transitory before acting. So this is something probably we have to draw the lessons from just very

[Interviewer]

top level, the differences between 26 and 2022. Inflation's not as high. What else do you see as the major differentiators between these two situations?

[Pierre Wunsch]

Well, you don't have the same level of bottlenecks that were all over the place and took us some time to understand that this was really a very specific crisis. The exit from COVID and then the energy crisis on top of that, where we had lost 40% of our gas supply from Russia. So we're a little bit less exposed now on front. But at the same time, after a long period of low inflation, economic agents, firms and workers were a little bit taken by surprise. So it took some time before people would react to the shock and you started having the second round effects. So I guess now the question is, okay, the shock might be a little bit less important from a European perspective than it was back then. But at the same time, it might be that firms say, okay, we don't want to be the last one to raise our prices. They might react more quickly. And then one of the big differences is that especially in Belgium and France, we don't have the fiscal capacity to absorb the shock as we did for Covid, or as we did for the Ukraine crisis, one of the concerns is that, and we see that in Belgium, if political parties want to do it as they did before and basically try to absorb the shock by increasing public expenditure, this might morph into potentially some tensions on the fiscal front. You might see some downgrades from rating agencies down the line. So far, I think we can deal with this crisis. I would say if we are not at the end of it by June, we're probably going to have to hike rates. But if it would morph in some form of financial crisis or tension in financial systems, then it truly becomes much more difficult to manage.

[Interviewer]

You said if we don't see resolution by June, we might have to hike rates. There is a rate decision coming this month. You will be voting on that. Should a rate increase be on the table in a few weeks or is that premature?

[Pierre Wunsch]

You know, in a way, hiking 25 basis points wouldn't change much. Inflation is already at 2.5%. We're not going to be able to control the direct effects of the crisis. We need to move at some point to control the indirect. So the issue is more of an issue of communication. What would you signal by hiking in April or in June? The way I feel comfortable putting it is if this is not done by June, I think we're going to have to hike. But I don't want to exclude a hike in April. Now, if this lasts, we are going to have also to work on demand. We need some demand destruction. So just giving subsidies for people to be able to keep buying gas and oil without feeling too much of an impact would not be the right policy because we need some demand destruction. And we've been able to reduce, for instance, natural gas consumption during the gas crisis after the war in Ukraine by 20%. But that was on the basis also of administrative measures like reducing the temperatures in buildings. So we need collectively to reduce our demand because there is just less gas and oil.

[Interviewer]

Earlier you mentioned 95% of your attention was being taken up by the Iran war. Are you worried that with this crisis commanding the headlines day in and it's distracting Europe from its other challenges?

[Pierre Wunsch]

Well, yes and no. I mean, the long expected hoped for recovery in Europe will be probably delayed again. At the same time, I think it will allow maybe to refocus, for instance on our energy policies where we had in a way bubble on climate ambition, that we were extremely ambitious and we thought people would back that. And then there was a backlash. We might refocus now also on the strategic autonomy aspect of it. We know we are dependent on the rest of the world, us, China, but also for energy, the Middle east on many fronts. And hopefully this is going to again confirm that we need to find a good balance between all these considerations and that we should not throw away the green agenda. I think the green agenda we need to be disciplined. It's difficult for the tradable sector in the energy intensive industry because we don't have cheap ways to decarbonize. But on the household front, electric vehicles, renewables, this is more or less a no brainer from this perspective. I think the current shock could help. It is also basically reinforcing again the feeling that Europe is to be united confronted with these shocks.

[Interviewer]

And do you feel that among your governing board peers heading into the end of the month?

[Pierre Wunsch]

Yeah, I think that the spirit is one of we've been confronted already with so many crises over the last few years. Broadly speaking, we've done what we should do. We were back at actually our target of 2%. So we'll have to do it again.

[Interviewer]

Pierre Wunsch is the governor of the national bank of Belgium. Governor, thank you so much for being with us on what's News.

[Pierre Wunsch]

Pleasure.

And finally, what's AI slop and what's not to try and stand out from the crowd, Journal marketing and advertising reporter Patrick Coffey says that some brands are now adding no AI disclaimers to their ads, hoping to be spared from a growing backlash against content made with we're

[Patrick Coffey]

already reaching the point where people are so distrustful that they're starting to assume, if they don't see otherwise, that things are AI generated. A recent survey from Gartner, a market research Firm, found that 68% of consumers regularly question whether the material they see online is real. Another report from a software Firm found that 63% of consumers think brands have a duty to disclose when they use AI in their marketing. But the rules at the moment are essentially that there are no rules. Every platform has made some apparent attempt to automatically identify and label AI generated materials, but they've already thrown up their hands and said this is just too big of a problem for us to handle.

[Luke Vargas]

While social media platforms may be sitting out this fight, some regulators aren't. New York last year became the first state to pass a law requiring that businesses disclose the use of AI generated humans in their marketing content, with the law scheduled to take effect in June. And that's it for what's news for this Tuesday morning. Today's 100% authentic show was produced by Hattie Moyer. Our supervising producer was Daniel Bach. And I'm Luke Vargas for the Wall Street Journal. We will be back tonight with a new show. And until then, thanks for listening.
