The double Ds - demographic & debt - & how that leads to the triple Ds - DEFLATION.

Ready?

#demographics World population growth rates are expected to slow, w/ contraction in many places (think Europe, East Asia - Japan, China, South Korea, etc).

We will grow at the slowest pace than anytime since 1950. Growth rate peaked in 1965-1970 👈🏻

#demographics Breaking this down into regions - very clear that Asian population peaking & will fall.

Look at Sub-Saharan Africa. Note that this is a projection & we shouldn't take anything beyond 2050 too seriously. The UN revises this very often but still useful for trends.

#demographics Let's look at contribution to population growth by country. Ready?

#1 India 🇮🇳
#2 Nigeria 🇳🇬
#3 Pakistan 🇵🇰
#4 Congo 🇨🇬
#5 Ethiopia 🇪🇹
#6 Tanzania 🇹🇿
#7 Indonesia 🇮🇩
#8 Egypt 🇪🇬
#10 USA 🇺🇸

#demographics Most populous country by rankings from 1999 to 2050 (2100 is a bit far away here). By 2050:

#1 India 🇮🇳
#2 China 🇨🇳
#3 Nigeria 🇳🇬
#4 USA 🇺🇸

China population expected to decline while US still increases. Indonesia drops out of fourth place 😱

#demographics Countries where population will DECLINE by at least 1% b/n 2019 & 2050. Ready?

>-20% decline is full of European countries
>-15% is Japan 🇯🇵 - Japanese people becoming rare
>-5% Russia, Taiwan, Thailand - also becoming rarer
>-2% China 🇨🇳 👈🏻

USA not there !

#demographics This is the mother of all charts b/c economists care about working age population to see if the change of labor will be helpful or a drag to growth. In East Asia, that will FALL SHARPLY.

In South Asia, that will RISE. A complete juxtaposition.

#demographics Once upon a time in 1990, the world was very youthful. Not too many >65-year old around (life expectancy lower). Only the UK & Nordic countries had >15% of population >65.

Today, everyone has aged & made fewer babies & so silvering. By 2050, on Africa is young 👇🏻🌍

#demographics We are not replacing ourselves fast enough in Asia (not South Asia however) & Europe. Why? Not having enough babies. Speaking of which, I was obsessed about Archie the royal baby last night - only 1 though, need 1 more to replace both parents.

Birth below 2 👇🏻👇🏻👇🏻

#demographics We are living longer (80s👵🏻🥳) & expected to live longer - so treat your body well as u have to see it for a while. Anyway, not good news if u work for a pension fund or social security office. Haha.

Oh wells. Long silvering stocks?🤷🏻‍♀️

#demographics People voting with their feet? Net international migration during 2010 to 2020.

Look at the USA 🇺🇸 - off the chart!!! A lot of net + migration (I moved to HK in 2011 so -1). Germany big too.

Who sees net outflows? India & China. Also Venezuela. Biggest is Syria!

#demographics This chart is just so heart-breaking for Russia & Italy & good for the USA & the Americas in general & Australia too!

Okay, so if u got net +inflows of people & net +natural increase (births>deaths) = HOT PINK (e.g., 🇺🇸🦘🇦🇺)

If deaths>births and net outflow = BLUE

@BIS_org

All about #demographics 👇🏻👇🏻👇🏻 - they got statistics too on urbanization etc. Free to download. Have fun!

population.un.org/wpp/Publicatio…

Okay, #debt - the fun stuff! This is the @BIS_org turf. The quarterly bulletin! @HyunSongShin - my fav economist 🤓

bis.org/publ/qtrpdf/r_…

@BIS_org

@BIS_org @HyunSongShin #debt We know that debt is not the issue b/c that is asset on the other side of the balance sheet.

But debt can be debilitating if income can't grow faster than the debt. Economists look at debt as a percentage share of income. At the macro level, % of GDP

Private debt % GDP👇🏻

@BIS_org

@BIS_org @HyunSongShin Let's step back & think about this for a second for those not in finance. Say your annual income = 100. But u don't want to stay at 100, u want to grow to say 200 in 10yrs & so u borrow $ & hopefully invest to upskill & not consume &that ur new skills gets u to say 200 salary. OK

@BIS_org

@BIS_org @HyunSongShin When u take on debt, u make 2 assumptions: a) the investment will payoff in making you more productive (rise in income); b) interest expense + payment sustainable.

So u have a problem if: a) income declines; b) interest expenses rise; c) debt too high & principal payment rise👈🏻

@BIS_org

@BIS_org @HyunSongShin Let's look at the situation & assume that all these economies make 100 per year. In the Euro area, private debt is ~160; Off the chart in Sweden at 240.

In EM Asia, China private sector debt is 210 for 100 income, Korea ~150, Malaysia >120, Thailand ~120

India & Indonesia low

@BIS_org

@BIS_org @HyunSongShin This is what we call the STOCK of private sector debt. When you have a lot of debt & the debt is greater than your current income, 2 other elements are important:

Time horizon to repay the debt & interest expense on the debt (how fast it compounds relative to ur income) 👈🏻👈🏻👈🏻

@BIS_org

@BIS_org @HyunSongShin If the term of debt is SHORT-TERM, u're in a pretty hurry to pay it back, which is basically a lot of China's private sector debt. So u're constantly needing to roll over this debt as it EXCEEDS income.

When this happens, if ur income growth is weakening, u'd want RATES TO FALL

@BIS_org

@BIS_org @HyunSongShin Ur risk appetite to take on debt's contingent upon expectation of higher return or paying this back won't destroy ur future well being (economists call this smoothing consumption as u're rational). If profits fall, rates sticky, expectations of future worse, have a flow issue too

@BIS_org

@BIS_org @HyunSongShin This goes back to @michaelxpettis tweet yesterday on it is not a supply but a demand issue in China. I think it is both. When a system is too leveraged, it only make sense to increase risk if the reward of that risk is big enough as debt payment burden high already.

Debt 👇🏻

@BIS_org

@BIS_org @HyunSongShin @michaelxpettis What's going on with growth? Globally, in places where demographic challenges are massive (Europe, Japan, Korea, China) & debt is high (same group), there is a growth problem. This is esp an issue if a country like the US is less willing than before to be consumer of last resort.

@BIS_org

@BIS_org @HyunSongShin @michaelxpettis So demographic (adverse transition) + debt (debt as a share of GDP>2 times) = Weaker growth.

But do not underestimate central banks' resolve to fight this pull. How? Lowering interest rates. Japan. Europe. Korea. and China too when it has space to do so once it sorts out protein

@BIS_org

@BIS_org @HyunSongShin @michaelxpettis In all scenarios of the World Bank's long-term projection, China growth will decelerate below 6% 👇🏻👇🏻👇🏻

@BIS_org

@BIS_org @HyunSongShin @michaelxpettis Today, the Bank of Korea raised its concern regarding the STOCK of debt Korea has & the deterioration of earnings (exports in double digits contraction) on the repayment ability, although says still OK so far. That said, Korean households debt/disposable income is 159%.

"The new approach is rooted in a core belief in Beijing: that Trump is fundamentally transactional, not ideological. Policymakers believe they can use Trump’s zest for a deal to neutralize the China hawks in his administration."

But Trump is a trade hawk. He has had the same view since the 1980s no matter what the "experts" have said. He is ideological in this point of view. He sees manufacturing as key to economic strength, the same as Xi actually.

https://x.com/Trinhnomics/status/1981537465157538079

Interesting to look at Xi and Trump meeting to compare Stalin and Franklin Roosevelt meeting at Yalta. Stalin had UK spies telling him all about the "red lines" for the UK and the US. So he came to the meeting totally prepared. Stalin was willing to give the US the "red lines" but in return, he took everything else, including territories in Japan, a foothold into Asia via China, and finally Eastern Europe, including Poland, where Churchill was busy drinking and talking too much to achieve much. This paved ways for Mao and the Communists to emerge in China. And the rest is history.

So does Trump have "red lines" that Xi know? If so, to get that, what would Xi ask in return? Interesting to see this playing out. Irrespective, we are entering strategic decoupling at great speed deal or no deal.

Another interesting fact to compare Franklin vs Stalin meeting was to look at Xi vs Trump's background. Trump came from wealth and has pretty had a pretty cushy life vs Xi whose father was part of the founding members of the communist party but was purged from the CCP and sent to work in factory. Xi essentially suffered as a child and teenager and grew up in China's tough decades.

Meanwhile, Trump grew up when the US dominated the world & still does but going through a tough transition. And so they both see the past and future in a different lenses.

Still, I think to think that Trump is only transactional and not ideological is not entirely true. He fundamentally believe in manufacturing and strategic autonomy and sees the US globalist agenda as a threat to national security, especially dependency on China for US defense supply chain. Lighthizer in the latest FT lunch interview also commented the same.

Good question. Let me just answer this with below tables.

First, whatever China lost in market share in exports to the US, Vietnam has gained. The best example is in mobile phones.

Now, is it REROUTING? As in just Chinese phones that are then trans-shipped to the US?

https://twitter.com/stevehou0/status/1978379197115519049

First, we have to realize that Vietnam went through two stages of FDI.

The first stage is driven by NORTH ASIANS that are basically fed up with geopolitical tensions and too much competition from China (think Japan in 2010 w/ rare earth and South Korea with THAAD but even before) and so what do they do?

They MOVE their production base slowly out of China into where? Well, for South Korea, it was Vietnam.

Samsung Electronics moved into Vietnam in the early 2000s to the point now more than 50% of their stuff is exported out of Vietnam. But not only. Many other Korean stuff.

Also Japanese etc. So what you see in the telecom here is not CHINESE PHONES but KOREAN PHONES.

The second wave of course is Chinese outward FDI themselves and also increasingly EUROPEANS.

Anyway, let's talk about phones.

For phones, the key thing I want to show here is that while Vietnam exports have grown a lot, over time, the IMPORTS of that have DECLINED.

And they have declined everywhere. People that look at China all day long think Vietnam only trades with China.

No, Vietnam is a relatively big trader for its small economic size so it TRADES WITH MANY ECONOMIES, the US and also South Korea etc.

Long story short here is that Vietnam is importing less of inputs while exporting more and that tells you that overtime supply chains are DEEPENING THERE FOR THAT ITEM. And it's not transhipment.

But what's RISING in imports FROM EVERYONE? WELL, capital intensive stuff. Vietnam is importing a lot of machinery etc from EVERYWHERE.

Note that it imports a lot from South Korea and Japan, Taiwan etc as well as China.

Did you know that Vietnam's Q3 GDP grew 8.2%YoY and Q2 was 8%? It is one of the few countries in Asia where manufacturing share of GDP is rising even as Chinese imports flood the market. Why?

“In contrast to other countries that are stuck in political paralysis, Vietnam has moved very swiftly to secure lower tariffs and reform its economy to increase productivity and competitiveness,” @Trinhnomics , a senior economist at Natixis SA, said. “This has allowed Vietnam to emerge as a winner under Trump 2.0 despite high tariffs because it’s favored as a foreign direct investment destination for those wanting to diversify away from worsening US-China tensions.”

bloomberg.com/news/articles/…

Look at manufacturing across Asia and what do you see? Its down for India, Malaysia, the Philippines, Thailand, Indonesia.

But not Vietnam. It's up. The fact of the matter is Vietnam faces a widening trade deficit with China but at the same time it has turned that into an overall trade surplus, which means that Vietnam value add has risen over time.

And you can see it clearly in its manufacturing share of GDP or global market share. Has been slowly steady climb.

This year, in 2025 manufacturing output surged 9.92% in the first nine months of 2025 from a year earlier, with around 77% of companies surveyed by the National Statistics Office saying export orders were higher or at the same level, a sign that US buyers are shrugging off the tariff hit for now.

What is Vietnam doing right? Well, first, the most important thing is that it wants manufacturing above all else. Vietnamese people need formal jobs and by prioritizing that, Vietnam is now focusing on the next leg of development, which is how to ADD MORE VALUE.

Blink and you will miss the biggest reform story of Asia. Vietnam literally redrew its map & made one of the biggest structural reforms in decades.

Rare earth is in the news again. Of course it is not rare, just that you gotta dig deep and then obvs process it. That entire process is polluting, costly and the output itself doesn't yield a lot.

That's how China has captured the market. It's willing to do polluting working and basically sells more not a lot. But having cornered that market, it also sees it as leverage, which it has used since 2010 (with Japan). The weaponization of supply chain is what we call it.

The free market economics of it makes sense for people to just leave it to China to do rare earth & then focus on the more market profitable business. Until, well, dun, dun dun.

So how should a firm or government view rare earth? Should you go and pay HIGHER price than what the Chinese rare earths are going for to then secure resilience of supply chain?

Most say, well, "Nah." That is a costly move because well, others will outcompete you with cheaper Chinese inputs while you go dig and refine your rare-earth magnets. Not an economically worthwhile endeavor.

But not everyone has taken that decision. Here is a story of a company that didn't: General Motors.

Here I summarize the great reporting of the WSJ Jon Emont and Christopher Otts.

As you know, we have known this issue for a long time & Japan knew about it since 2010. So the Japanese usually have about 1 year of this stockpile, just in case. Not the Americans.

The car industry is pretty dependent on rare-earth magnets. GM decided that Covid shocks, which left it with semiconductor shortage, that it should secure non-Chinese rare earth magnets.

This sort of decision takes years to bear fruit so it is one with risks. Why? Well, your competitors can buy cheaper Chinese rare earth while you are trying to get more expensive non-Chinese.

Here we go, as I'll go on TV soon with @JoumannaTV to discuss data, let's take a look at China September trade data that just came out.

September exports rose 8.3%YoY in USD and imports increased 7.4%YoY.

Year-to-date, exports grew 6.1% while imports declined -1.1%YoY.

By destination, China exports to the US fell -16.9% but to Asia rising rapidly.

Exports to India rose 12.9% and India deficit with China is accelerating, with imports not just intermediates for production but also final consumer goods.

Shipment to ASEAN rose 14.7% with fastest growth to Thailand and Vietnam (+22.5% and 22.3%, respectively). The sharp increase of shipment reflect supply chain diversification but also rising imports for domestic demand in ASEAN that also poses challenges to domestic industries.

Exports to the EU rose 8.2% with shipment to Germany increasing +10.5%.

Interestingly, China exports to Russia has fallen this year by -11.3% as Russia puts up curbs to some Chinese exports.

China trade surplus in September:
#1 EU 22.9
#2 USA 22.8bn
#3 ASEAN 17.2bn
#4 India 10.3bn

Should the US drop quarterly earnings? Well, the UK doesn't require it and neither does the EU.

Is it a controversial idea? Many people think it's a good idea to ditch it, including BlacRock CEO Larry Fink.

Fact: Hillary Clinton is also not a fan of quarterly earnings requirement.

It's one of the reforms people think will reduce shorterm-ism that is rather bipartisan.
ft.com/content/d5d463…

Here is Hilary Clinton going off against quarterly earnings.

Interesting that they got only quotes in that article of people thinking it is a terrible idea to get rid of it.

A lot of people think getting rid of it is a good idea.

Btw, companies can still report quarterly earnings. The SEC is saying you don't have to if you don't want to in proposing it.

European companies report quarterly earnings. Some don't. It's the optionality that's key.

theguardian.com/business/us-mo…

You can watch Hillary's actual speech. She's against quarterly earnings.

Many people are. Quarterlyism capitalism.
