Episode description

Across developed markets, bond markets are staging a slow-motion car wreck. As Opinion columnist and senior markets editor John Authers puts it, the phenomenon is truly global. Authers and Robin J. Brooks, a senior fellow at the Brookings Institution and former chief economist at the Institute of International Finance, join host Stephanie Flanders to explain why investors have turned sharply against government bonds across the world’s major developed economies — and how the fallout could affect us all.

I'm definitely Flannder's the head of governments and economics at Bloomberg. And this is Trumponomics, the podcast that looks at the economic world of Donald Trump, how he's shaking the global

economy and what on earth is going to happen next. Well, this week, I'm sorry, but we need to talk about bonds, government bonds, because investors have turned against them in a big way in the major developed economies in the past week, in what's been called a slow motion car wreck that could affect us all, especially anyone looking to take a

loan out or refinance their house. Now, remember that a sovereign bond is an IOU that a government sells to investors when it hasn't raised enough money in taxes to pay for all their spending, which these days is all the time. There's a lot that affects the price of that debt, but broadly, when investors are keen, the value of the iou goes up and the yield the interest

rate the government has to pay, goes down. That happened for many years after the global financial crisis, governments found borrowing cheaper and cheaper, but yields have been rising off and on since COVID, and last week years went up everywhere all at once in a way that made even

the more gray haired Bloomberg types pay attention. We're recording this on Tuesday morning, US time, and the yield, the interest rate on the very long term thirty year US treasury has just risen to its highest level since the eve of the global financial crisis in two thousand and seven. And it's not just the US. In Japan and the UK, for example, the thirty year yield is the highest it's been this century. Now this matters, obviously for government's funding costs.

Taken together, the past week could mean tens of billions in interest payments by governments that could otherwise have been spent on other things. But it also matters for markets as a whole, because of what it might tell us about the impact of the war in a rack on the global economy, the future rate of inflation, and also what it might tell us about the basic standing of

the so called advanced economies. Because you can't help noticing many emerging market governments have not seen investors running for the hills in the past week. In fact, many of their currencies have been going up. Well, there's so much to discuss, and my two guests have already written some excellent commentary on it that I thought was worth sharing

on the show. Robin Brooks, a senior Fellow now at the Brookings Institution, was formerly chief Economist at the Institute for International Finance and chief FX strategist at Goldman Sachs. He writes a lot of good stuff on his substack, but one piece this week, entitled Liz Trust Bond market blow Ups particularly caught my eye. Robin, thanks very much waking up early on the West Coast for us.

Speaker 3

Thanks for having me on.

Speaker 2

And John Author's a senior editor for Markets and Bloomberg Opinion columnist, long time Financial Times journalist, Welcome back to the show.

Speaker 1

John, Thanks for having me.

Speaker 2

I did steal in my quote earlier. I stole the title of your column today, the Great Bond car Wreck in slow Motion, without going into everything all at once, briefly, are we right to be taking the last week pretty seriously what's going on in bond market?

Speaker 4

Yes, you should always take what's going on in the treasury market very seriously, indeed, because it ultimately is the closest approach.

Speaker 5

We have to a risk free rate.

Speaker 4

Yes, there's no such thing as a risk pre rate, but for any number of different financial calculations, the closest approach to it, for one, that is assumed to be the risk pre rates of the.

Speaker 5

Ten year treasury yields.

Speaker 2

So it's a base for everything.

Speaker 4

It's a base that finds its way into an awful lot of financial calculations that you would not connect in any way intuitively to the treasury market. So it's a very big deal, obviously primarily for US mortgages, for the US companies trying to raise finance, or Uncle Sam trying to finance itself. I think the other point to make is that there is perhaps a greater, more important meaning

when global bond markets move together. So there are very specific local factors in Japan with Sanatakaichi, with France with the great difficulties there that Macron is having, with the legislature there, with the UK and all the ructions at the top of the labour parts, and there are certainly clear, different idiosyncratic things going on in all of those countries. But it's still has to be pointed out that it's difficult if you look at a chart to tell the difference between their bond markets.

Speaker 5

They have all started surging.

Speaker 4

Bond yields have started surging upwards at the same time, and that is ultimately because of uniform concerns.

Speaker 5

About fiscal space and about inflation.

Speaker 6

Robin.

Speaker 2

I did see a nice kind of quote in one of the many Bloomberg pieces about this was that the developed world has too much debt, little fiscal discipline, and no political appetite for fixing either. Do you think that's been driving the last week and why has it happened so quickly in such a short time.

Speaker 3

Well, I think that's the key question, Stephanie, And let me just add to what John said the three points. The first is that COVID saw fiscal stimulus globally of a magnitude and a global coordination that we've never really seen before. I remember talking to a policy maker at the time and they said, you know, we don't know what the long term consequences of this are going to be.

So many countries issuing so much debt simultaneously, and I think part of what we're seeing in recent months, including this week, is the bill is coming due for that. The second thing is that the decade before COVID, we were all convinced that inflation would be low forever, that interest rates would be low forever. We were all telling ourselves that we were in a new paradigm and output gaps were big, and so that meant you could issue lots of debt without interest rates going up very much.

And that caused governments to run deficits that even after COVID, even with COVID long gone, are way wider than they were before. So if you look at the US government, the deficits running around six percent of GDP, other governments are running deficits, they're way wider before COVID. So not only did we do a huge debt issuance binge during COVID,

but we continue to run really loose fiscal policy. And then the third thing is that inflation, which we thought was always going to be low, has turned out to not.

Speaker 5

Always be low.

Speaker 3

We had the post COVID inflation surge and now we have a run on oil prices and what that means for inflation. So I think, Stephanie, to come back to your question, all of what's going on in debt markets

has been brewing for many years. Long term interest rates, which in particular capture risk premium and expectations among investors for what governments might do, and of course the big bugbearers that governments will be tempted to inflate away debt, right to print money, to lean on central banks to make debt go away. I think all these fears have been coming to a head over the past year, and it's not a surprise that in connection with that we've

seen the debasement trades. So precious metals go through the right.

Speaker 2

To expect the debasement trade for those who might get panicked even more by.

Speaker 3

Hearing that people buying any kind of safe haven asset that will protect them from governments inflating away debt. So that is gold, silver, platinum, palladium, you name it. But it's also currencies and debt of countries with very low debt levels. So for example, Switzerland is kind of the Sinoquannon, but Sweden all the Scandies are part of that too.

Speaker 2

You make the point, John, I was struggling with last week actually because in the UK, obviously there was a lot of noise coming out of Westminster, and in Britain we like nothing better than to say that we're in the worst possible state relative Doughty body else, and everyone wanted to look at the bonds and say, the reason why yields have gone up so much is because this

government is terrible and this government is a mess. And I found myself in a rether difficult position saying, well, this is that is true, but actually there's a lot going on, And in fact, the biggest factor that's increased the cost of government was these other things going on. And as you say, you can't necessarily tell the difference between their political crisis and the things going on in

the US. But we've just been talking about long term things, structural things affecting the way that investors would look at bond yields. So you still might say, okay, but why has it all happened in the last week. I mean, is it sort of people suddenly realizing that the straight of horror moos is going to be shut for a long time because they can't be suddenly realizing that governments don't want to cut borrowing.

Speaker 4

There is I mean, Malcolm Gladwell got rich with this infuriating concept of the tipping point without ever explaining exactly when or why a tipping point will happen. There are such things as tipping points. Plainly, this happens in markets when some kind of a weird psychological chourn or some point in mass psychology is reached and things start to move very fast. It would be ridiculous to say this is all about the straight of Horne Moos.

Speaker 5

However, plainly that's the trigger at the moment. If you want to.

Speaker 4

Talk in the short term about why particularly this was a trigger, my best guess is that there was some hope out of Beijing last week that there would be some pressure from China on Iran to reopen the strait, and it didn't happen, evidently, And if you look at prices for Brent prices for December, they continue to reach a new high for the crisis. We're now above ninety dollars for Brent at the end of the year. That

is followed by people in bond markets. They are being told by the oil market that yes, this isn't a transitory thing, this is going to last for a while, and therefore the risks for creating an inflationary impulse have risen. Ultimately, again, it's an irritating glad well, it's happened to happen last week. If you wanted a specific moment last week that helped things run, maybe let's try to make ourselves feel important as Brits. Maybe the guilt's market helped. But the main

thing is oil. If we're really expecting crew to be above ninety dollars by the end of this year, which we weren't even a few weeks ago, there does come a point of view just have to act on that.

Speaker 2

We tend to say as economists, well, if you have these long term structural changes, and inact our economists, you think that there's a kind of long term increase in interest rates in the sort of neutral real interest rate globally from lots of big tectonic forces. But you tend to say that's manageable. If it happens over time, slowly, a big increase like we've seen in the last week, and certainly the big increase in borrowing costs we've had since the start of the Iran crisis, then you start

to worry. US treasuries are the kind of central common denominator for the whole global financial system, and there have been worries at various times in recent past about the short term liquidity in those enormous markets that you would have thought would never happen. Are you nervous about unexploded sort of grenades that could go off just from this move having happened so fast.

Speaker 4

Yeah, if you remember that to long term capital management, or particularly to two thousand and seven two thousand and eight, you always have to be concerned about that. I think this Robins piece covered some of our own analytics at Bloomberg.

Speaker 5

That I mean Japan and the UK.

Speaker 4

You can see some signs of stress, but still nothing like the very serious financial accent that happened with Liz Truss. There's no really clear sign of stressed trading here in particularly here in the US.

Speaker 5

Obviously there was that.

Speaker 4

Would be a reason for very great concern. This looks more even if we've reached some kind of a tipping point, more like a healthy as far as it goes, a healthy.

Speaker 5

Adjustment, a healthy realization.

Speaker 4

Then the concern obviously has to come into other markets. Are they really going to deal with what the bond market is telling them?

Speaker 5

Which soap? Are they? In many cases are not.

Speaker 4

The other thing is, if you've lived through two thousand and seventy two, you can get it.

Speaker 5

You can get into this thing as that. So it's fine.

Speaker 2

It's true we have we have too many terrible things to compare it to.

Speaker 1

It's true.

Speaker 4

Yes it's not in that territory at all, but but it is it ought to be healthy. There is no clear sign of really dangerous instability or liquidity to this state.

Speaker 2

Well, John, you're not a central banker, but I suspect you know we could in a few weeks time, depending on what happens, we can come back to you with healthy the way people came back to came back to j Powell with transitory.

Speaker 6

Robin.

Speaker 2

I quoted your substack about the Liz Trusts bond market blow ups, and I think when people hear that phrase, they will think, oh, he's talking about great drama and crazy politicians doing things. But actually you made a specific point that actually relates to this healthiness thing. Because what we might call in a developed economy, a healthy adjustment in bond markets wouldn't usually come with a fall in

the currency. So that was the thing that you'd highlighted, and I just wanted to dig into that.

Speaker 3

A bit in the g So, in advanced economies, typically higher yields mean a stronger currency, right, it increases the yield that you get a holding that currency, So it is very unusual to see yield spike and the currency fall.

That is kind of what happens in emerging markets, and it is a symptom usually of policy credibility being relatively low, so that when you have a shock, people aren't confident that the policy framework is stable, and so they are worried about central bank credibility being undermined, the central bank being pushed into printing money, and therefore a loss of value across the board, and so they bail on the country, They sell all assets, and so the currency falls in

addition to government bond prices falling and yields going up. The biggest example of this that we've had in the G ten, or I should say the most volatile and kind of the loudest, was the UK in the LDI blow up in twenty twenty two in September and October. But the thing is we're seeing more and more of these instances across the G ten, and I think that's symptomatic of US converging in the G ten down to EM, and of course that also means EM converging up to

the G ten. And another example of a similar blow up is the US in April twenty twenty five when Trump rolled out reciprocal tariffs and everyone was wondering what was going on. The dollar fell as yield spiked. That was a very scary episode. And as you know, the US treasury market has major vulnerabilities because of the basis trade and the swap spread trade. Those are high pockets of leverage which wobbled at the time. And then the thing that I highlight in my substack piece is Japan.

Japan is the mother of all of this has been in a Liz Trust style sell off for two years. It's crazy and it doesn't really get the attention that it should. But yields, especially at the long end, have been rising continuously in any G ten currency setting. You would think that that would boost the yen, but the yen has been falling and it is really really worrying.

And it basically to me says, if I think about what should the yield for Japan be, then with gross debt of two hundred and forty percent of GDP, basically markets are saying, well, I would like a yield that's much higher. I want to be compensated for all the risks that come with such a high debt level, what we're getting is a far lower yield, and so I'm

going to sell the currency. And so all the shenanigans that Japan currently is trying, and I'm referring specifically to official effects intervention, you know that.

Speaker 1

Stuff, it just doesn't work.

Speaker 3

It's basically just signaling a government in denial.

Speaker 1

Robin.

Speaker 2

The way you sort of particularly cross my radar when I was sort of first involved in this world was as chief economists the Institut International Finance. That's the institution that sort of has particularly gathers a lot of good information on what's going on with investment flows across the world.

And I just wonder, as someone who sat for a long time looking at both emerging market economies and the big G ten economies, are we getting to the point that or at least the trends that you're talking about, does that mean that you're going to start not being able to tell the difference? You know, if you're not given the name of a country and you look at their bond market, they're currency done, and it's that you're going to start not being able to tell the difference

between them. Are we already at that point.

Speaker 3

We're already well on the way to that. If you think of Eastern European economies, some of which are now in the EU, you know, back in the nineties they were considered emerging markets. I think they on most metrics these days surpass some of the older members of the EU in terms of their fundamentals and debt levels. But let me give you a concrete example of an emerging

market that really stood out positively after COVID. G ten central banks were trapped in kind of this pre pandemic think bubble, which was inflation will always be low, and so they dismissed the inflation surge that happened after COVID. And then you look at a central bank in Brazil which basically said, yeah, no, we're going to hike, and they hiked early and much quicker than G ten central banks.

So we are seeing a shift, of course, has been a long time coming, as you say, and I think emerging markets if you look at their currencies against the dollar. One of the things that I've been highlighting is that emerging work currencies are on a big trend appreciation against the US dollar, and that's really about convergence of em Central Bank and other policy making decision making and credibility to the G ten.

Speaker 2

It does make me think, John, we tend to talk about the US having an exorbitant privilege because of its the dollar status, and obviously that's still the case in many ways. But in a way, these G ten economies have been trading on a kind of exorbitant privilege that somehow they felt they could get away with having these very high debt levels and they could do everything that

emerging market economies do. But somehow, because they were developed and advanced and they've been around for a long time, they could get away with it. And people would specifically point to Japan as the example of that. Well, they still don't have to pay very much to borrow despite having these extraordinarily high debt rates. I mean, is that just now very rapidly going into the past.

Speaker 4

Yes, it is, but there are still some very important

market effects of that dawning realization. The one way to measure this that I think is fascinating is that is the carry trade, which for the uninitiated is a very popular way of playing the foreign exchange markets, where you borrow from a currency that has a low rate such as most obviously the yen and parket in a currency with a much higher where you can get much higher rates, such as at the moment, the Mexican peso, and you pocket the difference between those two interest rates, known as

the carry and providing there isn't a sudden turn in the interest rate in the exchange rate against you, you make money. The Japanese yen Mexican peso carry trade has made a higher total return in this decade than the

S and P five hundred. All it is is just leveraging the fact that Mexico knows it's got a problem with inflation and will hYP rate as soon as it sees there's a risk of inflation rising because it's an emerging market that's been hit several times in living memory by terrible financial crises because of this, while Japan is a country where you need to be about sixty years old to remember there being any problem with inflation at all, and behave differently, and you can simply make that kind

of that kind of money you can do better than buying the US stock market, just by leveraging that difference.

Speaker 5

Now that that cannot go on much longer, it seems to me.

Speaker 2

So you've mentioned the equity market, and I did want to ask you maybe this is sort of the last bit of our conversation, but you know, anyone listening to this would think, wow, the world's quite scary place. I mean, not only have we got the obvious Iran war, but actually the market's telling us that inflation is going to stay higher, that the governments credibility across the advanced economies, the economies that still play an enormous role in the

global economy, their credibility is shot. They're not able to convince investors that they're really going to do the difficult things to reduce their deficits. And we know that the voters in those countries don't want to do anything, don't want to face up to that reality. Particularly. But despite all of those long term fears that are supposedly represented embodied in this big increase in the cost of borrowing for governments, the equity markets don't seem to have really noticed or cared.

Speaker 1

How does that work?

Speaker 4

To be fair to equity markets, As many of my readers kindly point out, that they have a strong tendency to be incorrectly bearish.

Speaker 5

About stock bucket, so to be fair to stop markets.

Speaker 4

There is something genuinely exciting happening in the earnings that are being generated by companies building out for AI, and the earnings that are being generated by semiconductors in particular recently have certainly been that would always give you a reason in an impulse to buy stocks. That's what you buy when you buy a stock at the future, a cash flow from the from their future earnings.

Speaker 5

That's that said.

Speaker 7

Yeah, I agree, it seems to me they ought to care a well. I mean, the classic Alan Greenspan rule of thumb is to compare the earnings yields the inverse of the pe your earnings per share as a proportion of the share price with the ten year treasury yield. But the general idea being that when you can get a better yield from bonds where the only risk you're taking is that Uncle Sam doesn't repay you than on stocks,

that probably means stocks are a bad deal. At the moment, the gap in favor of bonds is its widest since two thousand and two, and it's not having any effect thus far on enthusiasm for stocks.

Speaker 5

Like I said, there are good reasons. There are two at least two huge shocks.

Speaker 4

Going on at the moment with oil and with their ai in the semiconductor trade, But all other things equal, you would think a move like this in the bond market would be.

Speaker 5

A serious problem.

Speaker 1

You stop.

Speaker 3

I just want to add something, which is that you know, equity markets can be forgiven for thinking that governments will put central banks under pressure to intervene if things get really bad. Think back to COVID in March twenty twenty.

I think the FED in the space of two months bought one and a half trillion dollars worth of treasuries when the treasury market was going crazy and yields were spiking during the pandemic in the summer of twenty twenty two, the ECB intervened to cab Italian and Spanish yields.

Speaker 1

And introduced new tools to keep.

Speaker 3

Those yields down. So there's a lot of intervention in government bond markets. What we see is kind of a parallel universe.

Speaker 2

But if you're trying to sort of balance the optimism in the equity markets, some of which is based on a lot of which is based on potentially quite sort of real positive developments in the real economy from AI, but also this loss of credibility potential challenges for governments

and governments financing. I mean, you'd have to at least conclude that we're going to have more inflation than we have, because that's even the kind of intervention you're talking about, Robin, eventually means a bit more inflation because you've effectively got some government central banks kind of buying up debt, which

is pretty close to monetary finance. John, It does seem like a bit more inflation than we might have expected if we add up all the things that Donald Trump is doing, all of the things we've been talking about on this program. That seems a fairly safe bet, doesn't it.

Speaker 4

Yes, And we came into the year expecting several FED funds rate cuts. That has an effect because it's highly difficult to see how we're going to get them any longer. Any shift like that in expectations for talking in the short term. In the longer term, there's always any number of demographic reasons to think that inflation will return this effective life. But in the short term, yes, there has been a clear turn, and people who were expecting rate cuts and not to go to get them, that will effect.

Speaker 2

All right, Well, we will see how it plays out in a sort of trumponomic world and more generally. But I'm glad I started with a bit of explainer at the beginning because this has been a bit more technical on the market front than we usually are. But I think everyone will have stayed with us. Thanks to you, to Robin and John.

Speaker 1

Thank you very much, Thank you, thanks for having us, Thanks for.
