There will be a lot written about financial deglobalization when folks pour over the 2018 data. But it is a mistake to fit last year's financial deglobalization into a Trump trade driven narrative.

It is basically a function of the shift in U.S. tax policy.

(thread)

1/x
The fall in U.S. outward FDI is entirely a function of a fall in U.S. direct investment in the world's tax havens; there was not real change in the pattern of investment in other economies.

(under the old law profits reinvested abroad could defer paying US tax)

2/x
The fall in U.S. FDI "reinvested" abroad in low havens had a host of other effects - firms building up assets in low tax jurisdictions were buying U.S. debt, inflating gross flows in both ways.

(there is actually a good fit in the BoP data here,using flows over last 4qs)

3/x
E.g. a lot of US FDI abroad was in practice the rising "cash" of a Techco (Ireland or Bermuda) sub, and a lot of foreign demand for US debt was coming from the same Techcos (or Pharmacos) offshore subs

4/x
I think I have found this in the BoP - the fall in cumulative FDI in a set of tax havens was mirrored by a fall in the cumulative purchases of U.S. debt of a slightly different set of tax havens

(cumulative flows = proxy for the stock" of offshore claims)

5/x
The match here isn't "pure." The debt holdings line for example includes Russia (which moved its reserves out of the US). But other Europe is the breakdown in the US data alas. & I couldn't include the Caribbean's holdings of U.S. debt b/c that was picking up something else ...
but I don't think it is totally spurious. here is the same plot for the set of EA countries that includes Ireland.

Both US FDI in Ireland & Irish holdings of US debt have gone into reverse (the fall in FDI tho is just a fall in the cash held by the Irish subs of US firms)

6/x
and since so much of this involved or touched a euro area country, it has similar implications for the euro area's balance of payments. FDI into the EA fell (US firms were "reinvesting" less in tax havens) and European demand for US debt fell ...

7/7
p.s. will do a blog on this too, but likely not til after labor day ...

The Treasury International Capital Data for September is now out -- China's Treasury holdings were constant during the data that was missed during the shutdown. Japan is up. UK and France are down a bit -- with a rise in the smaller EU custodial centers

1/ Image
The runup in foreign holdings of Treasuries has all been "private" -- tho note that funds that China holds in private custodians in Europe register as private, so the split is imprecise

2/ Image
The Treasuries that China holds in US custodians is clearly on a structural decline -- so estimating China's true holdings requires making a guess about China's holdings in custodians outside the US/ funds handed over to private managers

Crazy current account numbers for Taiwan in q3 -- a 20% quarterly surplus, and q4 looks like it will be bigger. That pushed the trailing 4q surplus up to 16% of GDP -- a record.

(and yet the TWD is weak, after hefty intervention in q3 changed the BoP dynamics)

1/ Image
Taiwan's soaring surplus though hasn't translated into soaring demand for bonds in the last 4 quarters -- bond purchases picked up in q3, but no longer are on the scale needed to match the huge current account surplus

2/ Image
That's true on a cumulative basis as well

A big new report from @AidData sheds insight into one of the mysteries of global capital flows, namely how does China's large/ growing current account surplus fund the US external deficit. The answer, in part, is lending by the state banks

1/ Image
The disaggregated data shows that China isn't just funding publicly guaranteed infrastructure projects in frontier economies/ Africa. Its state banks also do a lot of lending to "private" firms, including loans that back Chinese firms going out

2/ Image
That includes funding a lot of China's strategic acquisitions -- Kuka in Germany, Nexperia in the Netherlands, Nexperia's (subsequently reversed) purchase of a chip wafer facility in the UK, etc

The Economist takes a look at Taiwan this week -- and its peculiar combination of a weak currency and a massive external surplus;

"[Taiwan has] the world’s most undervalued currency and one of its biggest trade surpluses."

1/

economist.com/briefing/2025/…
The explanation for Taiwan's exceptionally weak currency (on the big Mac index & pretty much any other indicator) is Taiwan's central bank "as Taiwan has exported its way to prosperity, the CBC has tried to avoid such a fate by suppressing the value of the local currency"

Agreed --

Data on domestic sales is clearly off -- Image
And China's net auto exports far exceed the 1.3 m cars Germany exported on net in 24 ... Image
Michael Dunne and others put China's production capacity at ~ 50m cars. EV production capacity by the end of the year should approach 25m cars, so the right answer depends on how much ICE capacity has been retired. Huge v the 25m internal market and 30+ m in current output

The old exportweltmeister has been dethroned -- and its economy is suffering at the hand of the new exportweltmeister (China).

That is the story told by both a new ECB paper and the FT in an excellent new piece

1/ Image
Put simply, Germany is the most exposed large G-7 economy to the second China shock (Japan has been buffered by an incredibly weak yen).

2/ Image
The impact of the second China shock is in all the relevant data sets -- & it reflects a clear Chinese policy choice: “As a country, the Chinese have been in the last years much better, more proactive, more consistent in going after the big technologies and conquering them”
