The protection that isn't there
With only 41% protected, an exit from US assets, if it comes, shows up in the currency market before it shows up in the bond market, and the sellers would be the same institutions that buy the government IOUs that do not come due for twenty or thirty years.
Pension funds and insurers in six markets, Japan, Canada and Taiwan among them, had protected only 41% of what they hold in foreign currencies against those currencies falling, as of June 30. That is the smallest share since at least 2015, according to Bloomberg's review of their filings (Bloomberg). These are the largest owners of US government bonds and US shares outside America, and the dollar is down about 2.3% this quarter. A falling dollar with the protection off means the losses land on the very institutions that hold the most. A Japanese pension fund that owns US government bonds is holding two bets at once: the bond, and the dollar the bond is priced in. Protecting the second bet means agreeing today to sell those dollars back into yen at a future date. That costs money, roughly the gap between short-term interest rates in America and in Japan, and for most of the last decade it was money wasted. The dollar tended to rise when markets fell, which cushioned the bond losses on its own. So the protection came off. The arithmetic that made that sensible needs two things to stay true: the protection stays expensive, and the dollar stays the thing that rises in a panic. Bloomberg's point is that both are being tested at once. Money-market brokers put a 94% probability on the Bank of Japan, Japan's central bank, raising its interest rate to 1.25% on September 17–18 (Nikkei), which narrows the gap between the two countries' rates and so cuts the cost of protecting. And the European Central Bank's own data say gold overtook US government bonds as the world's largest reserve asset last year (FT), which is not what you would see if everyone still trusted the dollar to be the thing that goes up. The mechanism that matters for us: when an unprotected holder decides to protect itself, it does not sell the bond. It sells the currency. Laura Cooper of Nuveen, a large asset manager, puts it plainly: given the scale of foreign holdings, "it doesn't take a dramatic change in positioning to matter." In other words, these institutions own so much that even a small shift toward protecting themselves moves the market. The dollar index, which tracks the dollar against a basket of other currencies, is 99.2 this morning, down 0.35%. The market data does not show this yet, and we are not pretending it does. This belongs in fragility, the slow-moving pile of tinder: a large, concentrated, unprotected position that nobody had to report until the filings came due.
