And as always, great to speak every month with Wharton Emeritus Professor of Finance, uh Jeremy Siegel, who is also a
00:00:07
uh senior analyst at WisdomTree. Jeremy, great to have you back with us this month. Thank you, sir.
00:00:13
Happy to be with you, Dan. Obviously, a lot going on when you're talking about the impact of the war in
00:00:19
Iran, but also uh we had a Fed meeting uh last before we talked to you last, and I
00:00:25
guess let's start there with the decision of no rate cuts. Give us your thoughts.
00:00:31
Yeah. The I actually let me start with Iran because 2 hours ago is Yeah. I mean, uh
00:00:38
I know that takes a couple days lag here, but uh 2 hours ago we did have a announcement of a you know, a 5-day
00:00:44
postponement that rallied the markets dramatically by Trump. Uh now, Iran has denied that
00:00:51
there was such contact, but uh the markets like the fact this is the first de-escalation.
00:00:59
Uh you know, of the war on one part. Um it is a lot of confusion and and a lot of hope. So, this was going to be Monday
00:01:09
an extremely tense day, very tense, and um uh we'll see how it unfolds. Um uh
00:01:19
you know, Iran is by far the most important um uh determinant of of all market directions,
00:01:29
uh not just oil, but equities, bonds, Fed action, and all the rest. Um let's
00:01:35
go to Fed action. Um uh Uh it was no one's surprise um uh that uh uh there was no change. Um I I'll tell you
00:01:48
what somewhat surprised me, and this has uh somewhat longer-term consequences, but
00:01:54
um that uh Fed Chair Jay Powell was very adamant that he will not leave the Fed until he's cleared of all
00:02:03
uh charges of impropriety uh that have been leveled by the Trump administration. Now, let me explain that
00:02:10
that doesn't mean he he will stay as chair. Um um uh it it might be that the the
00:02:18
Senate will still confirm Warsh as chair, but as we know, uh Powell has 2 more years left, and there's no way
00:02:28
that Trump can remove him. Um uh you know, uh so basically, uh he's saying, you know, if you want me out, um
00:02:39
>> [laughter] >> end the end this thing. Yeah yeah that that So, that's
00:02:43
significant. Now, I'll tell you why it's significant, because if if Powell stays on, even if Warsh
00:02:49
becomes chair, I mean, you know, he uh Powell have an influential voice as ex-chair.
00:02:56
Right. Can sway a number of people, and um I I expect there to be some very close votes uh coming up in June when
00:03:05
Warsh takes uh the reins about whether to cut rates or not. Now, everything depends on what happens in Iran, if oil
00:03:11
goes back or not, and etc. etc. and so on. So, you know, I mean, uh you know, there's there's many months to go, but
00:03:19
um it's a very interesting position. Um let me also say something that I uh is I
00:03:26
thought was very significant, the long-term real growth rate in the US, um which is predicted by the Fed
00:03:33
officials, the 19 FOMC members, was raised by the most in its history by two um 20 basis points, 2/10 of a percent, from
00:03:44
1.8 to 2 percentage points. In other words, what they think the long-term real GDP growth is. That has never
00:03:52
happened before. It's the biggest increase in a 3-month period. Why does that matter? It
00:03:58
I think that confirms their belief that AI is in fact productive and will raise the growth
00:04:07
rate in the United States. Um there's very there's you know, very little else that happened
00:04:15
in the last 3 months that could explain for that big an increase. And by the way, um I won't we won't go into it
00:04:23
unless you want to, but an AI increase in real GDP growth is extremely uh um important for the long-term fiscal
00:04:33
viability of the deficit and and government spending. But uh So, this is >> me change.
00:04:39
Let me play Let me play off of that, because we've also in recent months seen
00:04:44
more and more companies making job cuts, seemingly linked to their path around AI, and it brings up the question I
00:04:51
think a lot of people would ask, and I've talked to a lot of labor economists
00:04:54
about it, and I'll ask you from from your side of it, uh you're seeing good
00:05:00
the expectation of this growth is there, but you also have this concern about the
00:05:04
labor force as well. So, how do those two kind of balance out as we move forward? Well, it's kind of interesting,
00:05:10
because you know, we've gotten some layoff what what you know, when you look at the
00:05:16
actual data, we don't see unemployment claims go up. Uh they're very uh we
00:05:22
don't see uh the the weekly ADP numbers that talk about the payroll. Yes, the
00:05:27
payroll was very weak um um in February, but it really offset unusual strength in January, and and
00:05:36
um uh really the equilibrium demand is zero, but the equilibrium supply is is zero. So, that's why the unemployment
00:05:44
rate is remaining the same. Uh Challenger layoffs, I think we're actually down.
00:05:49
Um job openings actually, I think edged up. Um yeah, we get Block, you know, laying
00:05:56
off 20,000. Uh they attribute I don't know if they attribute AI or not. Many
00:06:00
people who studied Block said they had hired way too many people anyways, and then it really wasn't related to to that
00:06:07
at all. So, you know, you hear a lot of anecdotal stories, but you don't you don't get any hard
00:06:14
evidence on the macro level that it's costing jobs. And and one has to understand, and I've written about
00:06:21
this, AI increases in you know, will increase wages and income, um and um it it ultimately will produce a lot of
00:06:33
demand from the extra income and productivity that it brings that will bring a lot of white even white-collar
00:06:40
workers demand will remain stable. So, I I think they the whole story of the AI labor apocalypse is wrong. Yeah. Um and
00:06:54
um uh the so Citrini report, which uh sparked the panic on Wall Street a month ago, um was cleverly written, but from a
00:07:03
macro standpoint, in my opinion, um completely unfounded. Okay. Uh let me finish up going back to kind of a
00:07:12
byproduct of the war, because we've seen the markets pull back a little bit,
00:07:16
obviously with what has been going on. Uh I think the expectation is if there's
00:07:21
some sort of agreement reached, we will see the markets move higher. Generally, what is your thought about where the
00:07:27
markets are right now, and how should investors be thinking about what we're
00:07:31
kind of seeing play out now, and I think the expectation has to be that at some point, we're going to see some sort of
00:07:37
balance come out from what we're seeing with Iran, and that the markets will get
00:07:41
back on the path we saw before this uh this war started. Yeah, that I agree. Uh absolutely. I mean, again, I don't know.
00:07:51
I mean, uh but let me say that the Iran situation is if if it isn't solved, if the Hormuz stays
00:08:00
uh closed, um and uh the the the the productive talks that Trump talked about are were not so,
00:08:11
um that's going to lead to further downside. Um there it there's just a global impact here. We are impacted much
00:08:18
less, but Asia is very impacted, and that impacts Now, I've I've been talking
00:08:22
to firms that for instance, they're using uh remote workers in Philippines. They're having blackouts in the
00:08:29
Philippines. They're the energy situation there is so bad that there's rationing, and then they can't get their
00:08:34
work out there. It it it it will be a serious effect. On the other hand, if we get that that oil moving again,
00:08:43
um there's no reason that the bull market will not continue. Let me finish up actually with one other thing,
00:08:50
because we've talked so much about oil through the Strait of Hormuz. The other
00:08:54
component that's very interesting is fertilizer, and how that can potentially
00:08:58
have an impact on the farming sector in so many different locations. Yeah, I heard that urea, which is one of the
00:09:04
main elements of that, that almost 50% goes through Hormuz, or I heard you know, that was one report, and
00:09:11
absolutely, yes, the fallout effects of not only uh um oil itself, oil derivatives,
00:09:18
fertilizer, um I mean, it is it is incredible that a little strait could hold the world
00:09:26
hostage. Um you know, Iran does not own that strait. Oh, some people say, "Oh, we're
00:09:32
going through Iran." No, it isn't. International law, they own 3 miles out.
00:09:37
There's still 20 miles of passage that's international waters. Um and um you know,
00:09:44
uh them blocking it or charging a toll as they suggested, etc. etc. really violates international law, and will not
00:09:52
be tolerated. So, again, let's hope some sort of deal is there. We all want that.
00:09:59
Um >> But uh I I do think what we saw is uh uh uh the first verbal on either side
00:10:09
de-escalation. I mean, which I think is hopeful and um uh uh let's um let's hope that that is in fact uh going
00:10:20
to prevail. Jeremy, I appreciate your time today. All the best. Thank you, sir. Thank you, Dan.
00:10:26
You got it. Jeremy Siegel, uh Wharton Emeritus Professor of Finance, as we mentioned, also with WisdomTree.
