A day that was a long time coming -- TSMC's dominance of chip manufacturing led Taiwan to post a $70b quarterly current account surplus in q4. That is $280b annualized, or a surplus of ~ 33% of GDP

Never though that would be possible for a non-tax haven without oil

1/ Image And there is of course a capital flows story -- as the TWD depreciated in q4 in the face of this massive surplus (2x its level in 24), and Taiwan technically sold reserves too!

I actually don't think Mark and I are that far apart

(tho I wouldn't start by arguing that a BoP deficit is meaningless, as I certainly find value in some cuts of the balance of payments + get annoyed when the IMF ignores the components of the BoP)

1/ The most policy relevant question is whether the courts will strike down the 122 balance of payments tariffs & I think the answer to that is likely to be no, for the reasons that Peter Harrell (an actual lawyer) laid out today

This is a thread that only Adam Tooze, a few international economist and a couple of very well paid trade lawyers are likely to enjoy …

The basic question is what did Congress mean back in 1975 when they wrote about payments problems and balance of payments deficits

1/ Image It is clear from the Senate report on the legislation that the authors were concerned about trade and payments surplus countries (Germany and Japan at the time) & the equitable sharing of balance of payments adjustment responsibilities across surplus and deficit countries

The mandarins at the PBOC are in a difficult spot -- a faster pace of CNY appreciation against the dollar has convinced Chinese exporters to bring funds back home, and driven the need to buy $100b a month (give or take) to control the pace of appreciation ...

1/ Image What's more, the slightly faster pace of appreciation v the dollar only drives an appreciation in the inflation adjusted CNY if the dollar itself isn't depreciating v other currencies, and if the pace of appreciation is bigger than the inflation differential

Great story in the New York Times highlighting the difficulties that the US government has faced in getting the world's most profitable companies to take supply chain security seriously, and reduce their exposure to a crisis in the Taiwan straights

1/ Image Seems like the median outcome for the US is that the efforts of Biden (CHIPS act) and Trump ("deals" negotiated with the threat of semiconductor tariffs) will just keep the US share of global chip production stable.

Me, in the Financial Times --

On the surge in China's intervention, and the impossibility of diversifying away from dollar assets/ Treasuries when the state banks are buying $100b a month in FX

1/ Image A statement from the heart --

The narrative around Treasury diversification that took hold after the Bloomberg story was a red herring. The real story was that Chinese intervention has surged and reached unprecedented levels

Striking how much of a drag net exports have been to German growth since the pandemic ...

1/ Image Obviously, this is because Germany's once substantial exports of autos, aircraft and machinery to China have plummeted. Those sectors used to generate a substantial surplus for Germany -- but not any more

So does the US have a balance of payments deficit for purposes of section 122 of the trade law (and thus the basis for imposing a 15% tariff).

It is an interesting question

1/ many Image One meaning of a balance of payments deficit is a current account deficit in excess of financial inflows, and thus a draw on reserves -- something that happens in emerging economies, but not generally in advanced economies with floating exchange rates.

The Trump administration is sure to use other authorities (122 maybe, 232, 301) to raise tariffs now that the court has struck down the IEEPA tariffs.

But striking down IEEPA still matters, particularly for China/other countries that aren't heavily hit by existing 232s

1/
Consider the structure of Korea's trade with the US v that of China. Korea export a ton of autos, which are still subject to the 232 auto tariff. Its steel is still subject to the 232 tariff there. & its chip exports could potentially be targeted by the semiconductor 232. 2/

Just how undervalued is the Chinese yuan --

the IMF (via the Economist) just revised its estimate up to 19% (plus or minus 4%)

1/many Image The IMF's 16% estimate in the Article IV was based on China's current account surplus though q3. The q4 data showed a bigger than expected surplus -- it pulled the full year surplus from 3.3% of GDP to 3.7% of GDP, changing the IMF's math ...

I think the best way to look at the underlying trend in the US trade data is strip out pharmaceuticals and gold (both were heavily influenced by the threat of tariffs, even though none were imposed on either category)

1/ Image I should note that this adjustment matters less for December than for previous months -- but cleaning up the data for the rest of the year helps isolate the trend

December goods deficit (ex oil) was back where it was in the fall of 2024, which seems like a fair read -- the October dip as a one off tied to reversing pharma front running a feared tariff and a reversal in gold flows

1/ Image the tariff front running is obvious in the import data for q1 2025 (heavily pharma and gold, which weren't tariffed in the end). there was some payback later in the year ... I think the December uptick in imports tho is a real signal

The latest IMF analysis of China (The staff report/ Article IV) highlights that China's export driven growth has come at the expense of its trading partners.

That is welcome, and very necessary message

1/many Image James Mayger and Jorgelina Do Rosario of Bloomberg reminded me that the 2024 staff report didn't mention external imbalances at all -- so there has been an important evolution in the IMF's thinking in the last couple of years

Goldman got a bit of attention by forecasting that China's 2026 current account surplus will top 4% of GDP.

I need a better publicist! The GS forecast is still too low

1/ Image Goldman's forecast -- which is almost certainly better than the IMF's forthcoming forecast -- isn't that bold. The customs surplus net of tourism (travel) is already 5% of GDP, and that should be a reasonable estimate of the surplus of a country with a positive NIIP!

My periodic reminder that the US TIC data doesn't measure China's holdings of US Treasuries. It only measures China's holdings of Treasuries in US custodians. The real question is how many Treasuries Chinese entities hold in non US custodians Image The total offshore assets of SAFE, the CIC, the SCBs (over $1.5 trillion now) and the policy banks likely approaches $7 trillion. SAFE's securities holdings top $3 trillion & other investors hold ~ $700b in foreign securities ...

There is an important debate as to whether China's exports have gone from contributing to China's growth to driving China's growth. Getting a third of reported growth from net exports is a lot, and domestic demand growth is debated

1/ Rhodium for example thinks total growth in 2025 was around 3% -- which would imply that the 1.6 pp contribution from net exports "drove" China's growth

Bloomberg reports that China's regulators have warned China's state banks about the risk of holding too many Treasuries --

The Chinese regulators must know something that the Treasury doesn't, as the Treasury data doesn't suggest that China has been buying any Treasuries

1/ Image The official US data on foreign holdings doesn't show any basis for Chinese concern -- China's Treasuries in US custodianship (in theory state accounts as well as state bank accounts) are heading down not up

The Treasury has indicated that it will look at the activities of China's state banks in its next assessment of China's currency policies--

It is hard to see how this doesn't become a bit of an issue ... unless of course summitry gets in the way of analysis 1/ Image It is quite clear that state bank purchases (and in 23/ early 24 sales) of fx have replaced PBOC purchases and sales and the core technique China uses to manage the band around the daily fx -- i.e. settlement looks like an intervention variable

A new blog on China's hidden fx intervention, which reached staggering scale in December 2025

Obviously overshadowed by the news about a Fed nomination, but the Treasury released its delated October 2025 FX report today and it is worth reading -- not the least b/c of a clear warning to SAFE.

1/ Image This seems clear

"An economy that fails to publish intervention data or whose data are incomplete will not be given any benefit of the doubt in Treasury’s assessment of intervention practices."

Can a country artificially weaken its currency by changing how it regulates its life insurance industry?

I think the answer is yes.

A new blog, one certain to increase my popularity with the Central Bank of China (Taipei)

1/

cfr.org/articles/taiwa… A bit of background. Taiwan's lifers hold $700 billion in foreign currency assets abroad (more counting their holdings of local ETFs that invest heavily in foreign bonds) v ~ $200 billion in domestic fx policies -- so fx gap (pre hedging) of $500 billion
