Ok, this is my last thread of 2021 & I'll talk about something that is MOST valuable in global exports - semiconductor - or chips, that powers the modern world. This is also very topical as we use it in our daily lives & at the center of politics & geopolitics given its shortages

https://twitter.com/SenWarren/status/1476327168833581056

In case you are wondering why we should know more about this most valuable global export item (worth about USD1trn & more valuable than oil), then we must not forget that in order for me to tweet this, we need chips. If we use the body analogy, chips = brain & oil is like blood.

Let's start with definition:
a) Semiconductor or in UN classification is known as cathode values & tubes & USD949bn was traded in global exports
b) It's a manufactured good & an INTERMEDIATE
c) U don't see it in the final product but products like CARS & laptops & mobiles need it

So the most valuable item in global trade is something you DON'T SEE as it is an intermediate product. You only see the final products such as cars/laptops/etc.

Chips are one of the US top exports (airplanes, oil, chips). China is a net importer of chips. Has a deficit of chips.

Meaning, money flows from China (USD350b) to chip exporters (North Asian countries like Taiwan (TSMC), South Korea (Samsung) & the US (Intel, Global Foundry). Let's talk about chips & its supply chain & why this is the US China trade-war & key to our national security (CHIPS ACT)

Chips were invented in the US & the US has 47% market share, Korea has 20% and Japan 10%, Europe 10%, & Taiwan 7%. China 5%.Now u may ask, well, why is the US fretting over chips if it DOMINATES. Because wants to retain the lead & this 47% includes design & manufacturing is less.

Before you say, "I'm so proud to be an American" and bask in your glory (well, I am rather proud), let's look at the value added by activity or supply chain of chips. And this is where the Biden administration (Trump before it) & Senator Warren are having issues: MANUFACTURING.

Let's put it a different way: American semiconductor firms are doing the R&D intensive part of the supply chain & they have OFFSHORED most of the manufacturing to Asia in various places in various segments of the supply chain, from Taiwan to Malaysia & Vietnam. India wants in too

Note that the US still remains MOST OF THE VALUE CHAIN but increasingly LESS. Consumes 25% of global semiconductor while China 24%, so the same. Europe about 20%.

So where's the beef? The issue is that we DON'T manufacture most of it in the US so have little control over supply.

I won't go into the R&D part of the US supply chain & go straight into the heart of the matter & why I quote Senator Warren's tweet, which I think is simplistic but sets the tone of the hour.

The USA lead in R&D but LAG in manufacturing. Who leads? Taiwan! Specially, TSMC.

To understand this chart, you need to understand a bit about chips but let me, a non engineer explain what this means: Foundries are where chips are manufactured. Manu of chips are capital intensive & very high tech. Basically u want smaller & faster chips & TW dominate < 10nm.

This chart shows u by region (basically we only have a few firms here so this is where Senator Warren goes off about too much concentration but the consolidation is necessary as it's EXPENSIVE to build a foundry).

TW & SK lead or TSMC & Samsung.
US has Intel + Global Foundry.

TSMC is ahead and DOMINATES <10nm & the US lags in this point. If u read the March 2021 US National Security Commission on AI paper, then it's all about the LACK OF MANUFACTURING in ADVANCED CHIPS that's a huge liability.

TMSC manus 54% of global chips.
nscai.gov/wp-content/upl…

Btw, the former CEO of Google is a key author of this report that calls for more support of US manufacturing of chips because it is the support from other governments that has allowed them to thrive.

Anyway, key pts are: we are good at R&D & bad at manu

nscai.gov/wp-content/upl…

Okay, let me wrap this up on why it matters to you, first, u use semiconductor as it is an input into electronics (the brain). U want a faster brain that is not too heavy right to help u with ur whatever tasks. Anyway, below is where the usage of chips is as a share of total. So?

Well, u know the SUPPLY of chips demand on INVESTMENT & it's capital intensive (at least 10bn for a decent foundry) & takes about 2 years. Plus we got Covid-19 related disruptions like Southeast Asia shutting down in Q3 2021.

Demand is HIGH & even acutely higher because Covid!

Note that I'm saying the following: we got supply that is relatively INELASTIC in the short-term for chips because of capacity constraints & time lag in investment & the fact we depend on TSMC for <10nm size. Second, operations were hit (remember my ASEAN note?) 3rd, demand high

@intel

Ok, so what happens now? First, the US will try to retain its lead. The Biden Administration has the CHIPS Act that has 52bn passed by the Senate waiting for the House to pass that gives incentives. Btw, @intel is basically the last American manu at the size that can compete. So?

Given that there is so much emphasis on getting US manu up to speed, one an reckon that more support will be lobbied by American firms, and specifically 2 left that manufacture & specially Intel to get it to the competitive level or the US won't have any (if can't compete, exit).

The US isn't the only country. EU has a similar strategy but the US has more to lose & what the supply shock crisis shows that we have too much concentration risk to East Asia & in some sector Southeast Asia for manufacturing in general & that means more diversification needed.

Arizona has emerged as a place where Intel is adding additional foundry (basically connecting to its existing). But TSMC is not silly. It is smart. It knows where the game is headed & building there too. So is Samsung.

In fact, TSMC also looking into the EU given policy shift.

Note that American firms such as Intel have a global footprint. Specifically, it has investment in Vietnam and just added USD7bn to Malaysia.

India just passed 10bn bill to attract semiconductor (it wants in too on the supply chain). Diversification will include ASEAN + India.

Hope I got u excited about semiconductor & know a bit more about the product that U DON'T SEE BUT SHAPE YOUR LIFE, CPI, INTEREST RATES, DOMESTIC POLITICS, GEOPOLITICS & geeky & cool at the same time.

And yes, I think the US SHOULD support the sector, both R&D & manufacturing.🙏

I have more too add but my threads always end up so long & let me end it by giving you the sources I used for this rant:

*Book: amazon.com/Fabless-Transf…
*The BBC video on semiconductor: bbc.com/reel/embed/p09…
*Policy paper: semiconductors.org/wp-content/upl…
*nscai.gov/wp-content/upl…

HNY!

@Trinhnomics

Have a happy new year! This was my way of saying thank u for being with me on Twitter Land. No matter how good/bad life is, key in my opinion is to focus on learning & processing what we learned to understand more about our world & each other!

See u in 2022!

"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.
