Let's go to the last part of the Miran's paper, which is currencies (Chapter 4 & 5).

Remember that his articulation of all the ills of the US trade imbalance is about the USD as a reserve currency & also the security support the US has to do (two burdens) that has grown, dwarfing the US economy RELATIVE size.

So let's talk about it. But before we even talk about, we have to go through a bit of economics history, if that is okay with you. We'll keep it pretty brief.
Triffin was a famous guy. He famously testified before Congress in 1959 & predicted the collapse of the Bretton Wood system, which happened in 1971 when the US broke away from the gold-dollar link.

What did he say? Well, simply, that as a gold-dollar reserve currency, the US would have to expand its liabilities as fast as required for global trade. But since it's backed by gold, which grows SLOWER than global trade, then we got a problem as lower rates would cause a run on the gold stock or dollar liabilities > gold stock.

And if the US didn't accumulate fast liabilities, well, global liquidity would shrink as US rates would go to high and cause global deflation.

If you want to learn more about it, see the paper below. The author btw isn't a fan of Triffin so says he got a bunch of stuff wrong and whatever he got right, it was probably not by design but accident.

Either way, he predicted that & got very famous obvs. What else did he predict?

bis.org/publ/work684.p…Image
Btw, the key reason the BIS author said Triffin was wrong/flukey is that dude didn't account for Euro dollar or USD outside the US (note at the time it was mostly Europe that held that hence the name & also the EUR was not even conceived although Charles de Gaulle was already pissed off about the dollar privilege & coined "exorbitant privilege phrase) so his timing of the "crash" was off. Either way, he was right for something and maybe it would have been different but either way, 1971, Nixon called the dollar-gold thing off.

Anyway, Triffin and went on to modify things because now we are no longer a USD-gold FX but just well, USD fiat currency.

So he now has a current account version of Triffin (btw, there's also a fiscal Triffin too). Let's talk about his current account idea.

He basically says this, well, as reserve FX or KING DOLLAR, the USD liquidity or USD liabilities will need to grow at the rate of global growth, which would lead to persistent current account DEFICIT.

Well, voila, the US did run since 1980s current account deficits (see graph from Miran's note).

Why? Well, it strengthens the USD and makes imports cheaper than exports + other countries' mercantilitic policy that makes them devalue their FX relative to their trade position.

BIS provides a bunch of counter arguments of why Triffin was off so read that but I won't summarize because, well, the point is to read the Miran paper and not why Triffin might be right for the wrong reasons.

Btw, the whole Triffin thing is about eventually, that things would become unsustainable.

But of course, BIS paper disagrees and say, well, FX would readjust and rates would adjust.Image

Okay, the fiscal part of Triffin. Note that Triffin didn't come up w/ this but more like fans/students of his. The idea is that reserves are mostly US govies debt and so there is a huge demand for this stuff that needs to be growing, and hence the dilemma, well, well, TOO MUCH DEBT. So we gotta make sure it's sustainable.

So here they debunk that by saying that supply of US govies debt > official global reserves.

Okay, let's talk about Miran now. Btw, I don't agree w/ this chart because FOREIGN PRIVATE BUYERS own a lot of UST too so official reserves is not a complete picture.Image

As the dollar is too strong (everyone wants this piece of hotness, which is less hot these days but u know what I mean), it causes a structural problem for the US, as in trade imbalances (Triffin here), and so on the FX side, they want a FAIR VALUED DOLLAR as other FX relative to USD is UNDERVALUED.

How are we gonna get there without, well, making dollar assets less attractive for investors???

If foreign investors expect USD to depreciate, investors flee say risk-free asset, which is UST bills/notes/bonds, then that would lead to the rise of longer end UST yields & with high fiscal deficits & debt & risks of inflation.

And w/ US housing are tied to the belly & long end of the curve (US mortgage rates are long-term), then this would be CATASTROPHIC.

Now if you add elevated inflation and depreciation of USD, then inflation would rise.

Why is this bad? Well, le Fed may not cut but may have to hike rates.

hudsonbaycapital.com/documents/FG/h…Image
He is pretty much more sanguine about impact of softer USD or MORE FAIRLY VALUED USD on equities because, well, American listed firms revenue are global so a weaker USD = earnings from abroad gets elevated so net net would probably be not so bad.

Overall, what is key is that while Trump does tariffs, which is inflationary whether FX is adjusted or not, and so he has to deploy DEFLATIONARY tools like LOWER ENERGY PRICES and DERAGULATION before currencies can be even considered.

As in, logic goes, TARIFFS + SUPPLY-SIDE support must go first before you even consider currencies measures as there are PLENTY OF RISKS.Image
Okay, so how are they gonna make the dollar FAIR again? Well, more history here.

Remember the Plaza Accord in 1985? Haha, of course! I was a baby so I remember that meeting between US, France, Germany, Japan and the UK all met to nicely WEAKEN THE USD or make it FAIR VALUE AGAIN! Also there is the Louvre Accord of 1987, remember that one too.

Anyway, while the price of the USD is determined by the Fed alone, as in they determine the supply of it, the DEMAND OF USD is determined globally. So we need to get tons of people on board.

Hence multilateral approach. But why would China or Europe or Japan want to make the DOLLAR FAIR VALUE, as in strengthen their FX versus the USD?

China got deflation and WE MUST EXPORT THAT!!! Expensive reminbi is not the way to get out of deflation.

Europe got inflation but WORSENING EXPORT COMPETITIVENESS VIS A VIS CHINA so not gonna do it.

Japan, ha, more possible. They are gonna raise rates anyway (he didn't write about this, just me adding to his narrative).

So he thinks that Europe and China won't cooperate on this plan because why would them? They want to export, export export!!!
He thinks that Japan, the UK and maybe Mexico and Canada maybe much amore amenable (Japan has been a great ally to the US). But the issue here is that they are not big and so we need the EU and China onboard.

They are not gonna do it willingly. So how?

Well, voila TARIFFS!!!!, WELL FOR CHINA ANYWAY. For Europe, well, we are gonna use SECURITY AS LEVERAGE.

For China, they will just raise tariffs till it hurts & then lower it if they are willing to adjust their FX.

He even mentions that accords are named where they are negotiated so this would be called a "Mar-a-Lago Accord."

Anyway, he says it's super super hard to do this and the world today is not 1980s.

The US has tons of debt vs 1980s and US size of GDP also smaller. So this accord idea is not gonna work...Image
Anyway, must consider other approach then. This one is pretty intense. Basically, need to marry SECURITY & TRADE & FINANCING (as in buying of USTs but not just any, super super long ones).

1) Security zones are a public good & country inside must buy Treasurys
2) Security zones are a capital good & funded by century bonds & not short-term bills
3) Security zones that are well, got tariffs, because you haven't swapped your bills for bonds.

What's the point of all of this? Is for the USD to get to fair value & let other FX appreciate vs the USD to help tradeable and manufacturing sectors.Image
Anyway, he goes, well, hard to get people to agree to do this btw because why would you do that? haha.

So we need to raise leverage. What's that? Tariffs (sticks), security (carrots), and tools to mitigate risks such as swap lines. Image
Dollar reserves today are in Asia & the Middle East and not in Europe like the 1980s and they are not as friendly as Europeans so not gonna work.

Basically, he's saying that the multilateral approach to dollar adjustment is not gonna work because in the 1980s we did it with friendly allies & now, well, hard to get it right.

On top of that, we got private investors, institutional and retail. They wouldn't want to term out their treasury. And their rush out the door is a big risk.

So for Miran, it's difficult the multilateral approach.Image
What about the unilateral approach?

Well, he says they can even if the Fed doesn't cut rates. You can charge a fee on reserve assets which disincentive them from accumulating it.

He says that domestic holders of UST already pay income tax so it just levels the playing field w/ foreign investors.

But doing that would INCREASE VOLATILITY. Because u basically want people to sell USTs (it's basically like lowering rates if you make people pay some of it - I personally get less income than foreign investors on my UST bills as I pay a tax), BUT NOT TOO MUCH SELLING.

How to find the balance? Well, you have to make the fees very very small & move very slowly. Gradualism he says!!!

And he says on NEW ISSUES versus existing US debt because, well, that would be unfair! hahaha.

Also the rates DIFFER for these fees.

Allies = < than Adversaries.

Oh we also need voluntary cooperation from the Fed too for helping w/ capping long-term yield but have independence on short-term rates.Image
Third option is reserve accumulation, as in accumulate foreign FX. But this is hard, the Treasury's Exchange Stabilization Fund is limited in scope/size. ESF can leverage but, well, that adds risks to the US gov.

And the negative carry issue as foreign assets likely yield less than the US right now.

Oh can sell gold to accumulate foreign FX but that is a very politically costly thing to do. But gold has no income so income side is positive but not like a good move.

Build a reserve portfolio at Fed SOMA. But Miran is like, well, not a good use of funds because u buy foreign assets that yield less than ours and so not a productive use of it (hahah that's why people own UST duh!) and the Fed can like buy foreign debt but that exposes the US to credit risks because well, other foreign gov, is well, u know, risky too.

Basically he considers more and more but that seems like not a good idea...Image
So here we get to the end and I must go because I am getting late to my appointment.

Miran says CURRENCY policies are super RISKY and so TARIFFS are to go first.

Only when the coast is clear, then we can consider this.Image
Conclusion, buy GOLD.

Just kidding. I gotta go. Hope you enjoyed it!

No, the US is not gonna buy cryptos & unlikely to sell its gold anytime soon given political risks. Image

Okay, let's talk about Trump end game. To do that, let's read Stephen Miran's "A User's Guide to Restructuring the Global Trading System" together.

Note that there's a disclaimer that this is not a policy advocacy but catalog of tools available for them to "reshape the global trading system."
hudsonbaycapital.com/documents/FG/h…
Trump has been talking about global trade & how he thinks the US trade deficit is unfair since the 1980s (see his Oprah interviews) so this is beef he carries and he has the power to do it.

Trump 1.0 was a test case and Trump 2.0 is going to go full steroid on what he views as the current world order not working for the US. It may work for u, but not for him & his team is going to change it. Here's how Miran is laying it out.
First, the root of all US problems & its imbalances lies in the overvalued dollar. Yes, others lament its "exorbitant privilege" (a French FM said it) but here Trump team & also corroborated by many economists, including @michaelxpettis that while it is good for US FINANCIAL SECTORS, terrible for MAINSTREET. So basically Wall Street gains at the expense of the VACUUMING out of US industrial base.

Emerging Asia Braces for Trade War Impact: Losers and Winners of Trumponomics

A thread. Let's go!

research.natixis.com/Site/en/public…
Let's start with the basics. What's on & what's promised/threatened. So far, on 12th March 2025, we have:
+25% on steel & aluminum on everyone (for steel, not new for everyone & just those that got exemptions. In Asia, that's AU, SK, and Japan. Canada & Mexico got exemptions and so did EU).
+20% on China, including Hong Kong.Image
Let's talk about the 20% on China. China is clearly targeted with 20% higher tariffs as well as its commercial ships, of which higher fees of docking in the US are being considered.

China will try to cope with higher tariffs as it did the past, which is offshoring productions to more neutral countries such as Mexico, Canada, Southeast Asia and sell more to the rest of the world as well as expanding relationships with the Global South (e.g. BRICS).

But with widening unilateral tariffs as well as others erecting barriers, this time around, beefing up domestic demand will be key.

Who loses in this tariff for Asia? China for US markets, but it will try to export elsewhere so there is a fear of a flood of Chinese goods coming.

Who gains? Well, it depends but those that can limit the flood of Chinese goods as well as export more to the US & attract investment. In other words, a lot of ifs but winners are possible.

Hello, I want to point one thing out. Vietnam is not just a rerouting place for China. How do we know that? Because Vietnam's biggest exports are not even Chinese investment - it's South Korean, yes Samsung Electronics.

People don't just invest in Vietnam because China is targeted. The shift happened before Trump trade war. See Samsung Electronics.

They do it because Vietnam WANTS that investment. It wants manufacturing. It puts it as a priority above all else.

And because Vietnam's cheap. It got cheap labor. It got supportive policy, both hard and soft infra.
Example, Samsung Electronics started moving out of China into Vietnam way before Trump trade war of 2018.

Why did they move to Vietnam? Well, the Vietnamese wanted it & provided tons of incentives.

And why did the Koreans move there? China was GETTING EXPENSIVE. And the Chinese are starting to compete with them.

And then there's the geopolitical issue between China and South Korea.

So South Korea started to move to Vietnam and once that became a success, it INCREASED INVESTMENT and then other South Korean firms came.
As the Koreans came, other firms followed, not just to export but if you go to Vietnam today, there are a lot of Korean brands/companies to target Vietnam domestic demand.

Same with the Japanese. Similar story. And it's not just to EXPORT and tapping into Vietnamese cheapness (this is not just labor but also ELECTRICITY & other inputs), but also to tape into Vietnam domestic demand.

A lot of Japanese brands in Vietnam, from supermarkets to malls etc.

Trump is exempting autos from Canada and Mexico 25% and my guess is more exemption is coming (energy is an easy one I guess even with 10% it seems ill-advised).

There is a ceiling to Trump tariffs and that's economic reality of higher prices (domestic production can't suddenly increase at the same pace as tariffs). If he paces his tariffs, targeting only certain sectors/country, then he can mitigate inflation fallout and shift supply chains. If too fast and furious, it leads to demand destruction.

And so here we are. He is backtracking but w/ looming threats of auto and reciprocal for 2 April. But markets sense that something has got to give.
And so US growth slowdown in the short-term as imports blow up with front-loading (even gold is getting front-loaded), and any surge of industrial production will take time, esp with capex intensive sectors like auto.

This leads to rate cut odds & stagflation risks. And so the dollar falls.

But it's falling from great heights so definitely due Trump tariffs or not.
Meanwhile, Trump Ukraine strategy, which is a US retreat from the Euro security scene, is making Europe Great Again, well at least for now DEFENSE.

The Germans are spending an exceptional EUR500bn & changing the constitution & everyone else is using this as a source of growth.

Short welfare, long industrials, especially defense. Yields rising as growth hopes rise! The FISCAL BOMB. Yes, it's happening and shall I say I say I saw this coming (said this to clients in Milan at a seminar).

And the winner of all of this? Yes, Poland!!! EPOL is off the chart! My children are Polish (a quarter & citizen of as well as the US) so I am happy about it.

Okay, I'm going to talk about what Trump has done & what I think he will do & then I'll talk about Vietnam. It's a long-winded way to get to that answer but necessary.

To understand what he will do, we must know his end game. Some people say, "Well, dude doesn't know himself. Look at his rambling."

Let's take a look.
Trump has been President for a month and 1 week. So far, in chronological order, what he has done:

4 February, slapped an additional 10% tariffs on China. This time, this is the first time that it includes Hong Kong. So while the amount is smaller than 60% mentioned, it widens in territory. This hasn't been rescinded and is ON. This covers roughly 14% of total US imports.

26 Jan he threatened Columbia 25% tariffs, mostly because they didn't want to take his deportees (remember he wanted to deport but to do that need origin countries to accept) - that was then solved immediately.

At the same time (Feb), threatened Canada & Mexico w/ 25% tariffs, also basically want them to take deportees and hold the borders so to speak, and that is delayed until 4th March but last night he rambled something like April. Irrespective, this is not yet implemented.
So basically, by the end of Feb, we only have tariffs on China (+HK) that is higher by 10%, effective 4th Feb.

Now, he has threatened to do more on China. What has he done? Well, this time, targeting its DOMINANCE in strategic sectors like shipbuilding & steel & aluminum.

Lets first talk about steel & aluminum before we go into shipbuilding.

As you know, this is not a new tariff. In fact, this is is a continuation of Trump 1.0 in 2018.

Good morning,

Everyone wants me to have an opinion on that FT article why Vietnam is going to be targeted by Trump just because China has invested in Vietnam. First, before we talk about the article I want to talk about what I think Trump would do.

And no, he's not going just put tariffs on everyone. Why? Let's talk about the US.
1st, everyone cares about what the US does because it is the largest importer of goods or 4.1trn of it.

So what it does regarding domestic policy or trade policy (import tariffs are basically tax on importers so one can argue that it is a measure to help domestic sectors or if it doesn't help w/ domestic production then it will raise costs). Either way, the tariffs themselves just add to costs of goods imported so that should theoretically help relative costs of domestic vs foreign.
Now before you say, okay, well then. Voila, no more imports if we just erect a wall of tariffs.

But no, the US has one of the most expensive labor market. Not only that, environmental laws. Yes, if you think the news says China is green just because it makes a lot of EV, then I got something to tell you. The US, especially certain states like California, got a lot of regulations that make it very expensive to produce.

Input costs like labor, land & regulations are key.

Electricity is not that expensive in the US and cheaper than Europe but frankly the US is not a cheapo place. It's an expensive place to produce something.
