🇺🇸 The US makes more sense if you think of it as the world’s biggest and most successful investment firm: America Capital Partners, or ACP.
Its business is managing access to the world’s most valuable business ecosystem — America. For decades, the rest of the world funded that ecosystem because America was considered the safest place to park money.
But the world is changing. These days, capital is less interested in safety and more interested in returns.
A few thoughts on what that means for ACP 👇
1️⃣ America’s trade deficit is the engine that makes the system work.
The US buys more from the world than it sells. As a result, it sends hundreds of billions of dollars overseas every year. In turn, countries that earn those dollars have historically recycled a large share of them back into the US by buying American assets.
For a long time, foreign nations behaved like lenders. They bought mostly US Treasuries, accepted modest returns and left the upside to America.
Only now are those investors starting to ask for a share of the gains.
2️⃣ ACP used to work much like Berkshire Hathaway’s insurance business. Foreign exporters parked their surplus dollars in low yielding Treasuries, accepting returns that barely kept pace with inflation in exchange for safety and liquidity.
Just as with Berkshire’s famous “insurance float”, that gave ACP an enormous pool of cheap, patient capital that could be rolled over almost indefinitely. Every maturing lender was replaced by the next country running a trade surplus.
America invested that capital into US businesses and other domestic productive assets that earned much higher returns.
The lender received a fixed return while ACP captured almost all of the upside and distributed it mostly to domestic investors.
3️⃣ As we say, past performance doesn’t say much about future returns. A system that has worked one way for decades is not necessarily bound to continue doing so in the future.
Indeed, over the past century, the world has moved from gold, to gold backed dollars under Bretton Woods, and then to a purely fiat dollar after Richard Nixon closed the gold window in 1971.
And as written by
@adam_tooze last week, the practice of central banks holding huge pools of unhedged dollar reserves is a fairly recent chapter in economic history rather than a permanent feature of the global system.
4️⃣ When most people think of the dollar, they’re thinking about the period after 2000 — what Adam calls “Bretton Woods 2.0”.
Back then, China (which had just joined the WTO) kept its currency cheap, exported manufactured goods to America, and accumulated huge amounts of US Treasuries almost automatically.
This was the era of safety seeking capital. Foreign central banks such as China’s wanted liquidity and stability rather than higher returns.
Per Adam, that era largely peaked around 2015.
5️⃣ The biggest shift today is who is supplying the capital.
China has stepped back, using capital controls to keep domestic savings at home and direct them into its own industrial base. I think of this model as “Middle Kingdom Ventures”, or MKV — a very different beast from ACP.
The money now flowing into America comes much more from Europe, Japan, South Korea and Taiwan. Most of those flows now come from private investors and sovereign wealth funds that are looking for returns.
Very different from the safety obsessed lenders of the previous era.
6️⃣ As the investors changed, so did their portfolios.
@Brad_Setser notes that the dollar still makes up about 57% of official central bank reserves. Among investors chasing returns, however, dollar assets account for roughly 65 to 70% of portfolios, and for some Taiwanese life insurers the figure approaches 95% 👇
They are buying America because they want exposure to the best performing assets, especially US tech companies. They have moved further up the risk curve in search of higher returns.
7️⃣ That shift is producing two very different flows.
Official reserve managers at the world's central banks are steadily moving into physical gold, buying more than 1,000 tonnes a year as a hedge against sanctions and financial risk.
Meanwhile, private investors are moving into American equities, especially tech, while remaining inside the dollar system.
8️⃣ Markets respond to flows before fundamentals.
Research from
@AQRCapital (Antti Ilmanen and Thomas Maloney, 2025) suggests that most of America’s stock market outperformance since the 1990s has come from investors paying increasingly higher prices for company earnings rather than from stronger earnings growth.
In our recent interview on
@CurrenPower with
@mariekeflament,
@michaelxpettis concurred with this idea: a soaring US stock market reflects the fact that enormous amounts of foreign capital, generated by America’s trade deficit, need somewhere to go.
And if more capital is chasing an ever narrower segment of the US stock market, prices have nowhere to go but up.
9️⃣ This is where the ACP model starts to come under pressure.
The old spread depended on foreigners lending cheaply while America owned the highest returning assets.
Now those lenders increasingly want to own the assets themselves, especially the best performing tech stocks.
That creates pressure from both directions:
• America still needs buyers for its growing pile of Treasuries, so borrowing costs rise as demand weakens.
• At the same time, the returns from owning the best assets are increasingly shared with foreign investors.
The gap between cheap funding and high returns is narrowing.
@adam_tooze calculated that foreign investors now own roughly $24.6 trillion more in American assets than Americans own abroad, leaving the US with a net international investment position approaching 90% of GDP.
🔟 One final difference between today’s investors and yesterday’s: safety-seeking capital is patient; return-seeking capital moves much faster.
The original ACP model depended on investors who were happy to sit quietly in Treasuries and accept modest returns.
But as inflation erodes real bond returns and confidence in the dollar becomes less automatic (euphemism), many investors have left the Treasury market and moved into equities.
They no longer want to finance America’s success from the sidelines. They want to own a larger share of it.
And once global investors begin chasing the upside, the world’s greatest investment platform starts to look less like Berkshire Hathaway and more like a hedge fund exposed to investor redemptions, where capital can leave when performance disappoints.
(This hedge fund comparison was made earlier this year by
@helene_rey.)
In other words, the lenders have become LPs, and they are no longer satisfied with a fixed return. They now expect the GPs to deliver consistent performance.
If they do not, capital can leave, especially as governments around the world rediscover capital controls and financial repression as tools for keeping domestic savings at home. That may very well be the next chapter — cc
