Given every part going on the earth — Mike Waltz leaving the chat; papal elections; GTA being delayed till 2026; and so forth — you’d be forgiven for not paying a lot consideration to Asian FX.
However right here’s a humdinger of a chart displaying the Taiwanese greenback’s change fee in opposition to the US greenback:

We’ve reversed the Y axis to indicate how the Taiwanese greenback has soared in opposition to the US greenback in latest days. Bloomberg informs us that that is the largest rise since 1988. Right here’s what the Borg says:
The Taiwan greenback surged probably the most in practically 4 many years as a combo of upbeat progress knowledge, bets on easing commerce tensions and robust US tech earnings turbocharged forex beneficial properties.
It closed about 3% larger in opposition to the dollar at 31.06 on Friday, marking the forex’s largest one-day advance since 1988. The island’s benchmark inventory index additionally climbed 2.7% to outperform the area’s fairness gauges.
The Taiwan greenback, which not often makes headlines, was on the middle stage of forex market on Friday as sentiment towards the island’s property dramatically improved after China stated it’s assessing attainable commerce talks with the US. Knowledge displaying the island’s economic system increasing at a faster-than-expected tempo and hopes that US tech giants will import extra semiconductors from the area additionally helped to fan optimism.
Sadly, it’s a little too late to name all of our favorite TWD sellers, however Alphaville is fairly assured that these causes are extraordinarily tenuous. The concept that a flurry of bets that the commerce conflict will ease abruptly despatched the Taiwanese greenback to the moon is, frankly, a bit fantastical.
We’ll put out some feelers over the weekend, however to us this seems to be much more more likely to be linked to a difficulty we highlighted in the beginning of the yr: Taiwan has turn out to be a monetary superpower because of its life insurance coverage corporations amassing a $1.7tn pile of abroad property, most of that are US bonds.

Nevertheless, as Brad Setser and Joshua Youthful wrote on the time, “what may seem to be each a mirrored image and supply of monetary and financial power can simply as simply be a obtrusive weak point”.
Taiwanese life insurers have apparently not been super-diligent about hedging their swelling overseas forex exposures, opening up an enormous mismatch between their Taiwanese greenback liabilities and their US greenback property.

When the US greenback’s 2025 decline abruptly started to speed up and broaden earlier this month, it in all probability triggered chilly sweats in sure corners of Taipei. As Setser and Youthful wrote for Alphaville in January (our emphasis beneath):
Variants of this story have performed out throughout Asia. The distinction is solely one in every of scale. Taiwan’s open place is solely a lot bigger and extra precarious than that of, say, Japan’s. And for sophisticated causes (associated to Taiwan’s closed monetary account) it can’t actually be ameliorated except the life insurers are allowed to borrow a ton from the central financial institution.
Which means any massive improve within the worth of Taiwan’s greenback — a rise that’s implied by the large measurement of Taiwan’s commerce surplus and the truth that it’s nonetheless weaker in opposition to the greenback than it was 30 years in the past — may obliterate the funds of Taiwan’s large insurance coverage trade.
To place it plainly, Taiwan’s life insurance coverage trade has wager its solvency (with the help of its regulators) on the idea that Taiwan’s central financial institution will be capable to keep away from a significant appreciation of the Taiwan greenback.
Our wager is due to this fact that the Taiwanese greenback’s sudden surge is brought on by native life insurance coverage corporations belatedly scrambling to hedge their greenback exposures. It will likely be attention-grabbing to see how subsequent week goes.
However there are hints that it’s already inflicting some contagion in locations like South Korea, the place the received has additionally abruptly jumped. We collect that some insurers have used it as a proxy hedge due to the prices of hedging in {dollars}. NB we’ve as soon as once more reversed the Y axis to higher present how the received is appreciating.

Usually, abrupt forex appreciations are lots simpler for international locations to deal with than violent forex swoons. In any case, the native central financial institution can all the time create an infinite quantity of its personal forex, and easily purchase abroad property with it (viz, SNB).
Nevertheless, the Central Financial institution of the Republic of China — as Taiwan’s is formally known as — is in a little bit of a pickle.
It has all the time been cautious of being seen to be weakening the Taiwanese greenback too overtly, for concern of being labelled a forex manipulator by the US Treasury. (That is why the Taiwanese life insurers in observe doing it on Taiwan’s behalf was such a boon.)
However it will likely be exceptionally cautious of intervening to weaken its forex at a time when the Trump administration is already on the commerce conflict path. In any case, Taiwan is sort of completely depending on the US for navy safety, and the authorities will probably be loath to do something which may upset Washington at a delicate time.
Sadly, this simply one thing that would trigger bother exterior of the nation as effectively. As Youthful and Setser identified in a follow-up piece, what occurs in Taiwan doesn’t all the time keep in Taiwan.
