MIKE DOLAN, ROI Finance & Markets Columnist: As summer drew to a close this week, cooler September air chilled sovereign bond markets, with traders bracing for rate hikes around the world this month.
The U.S. 10-year Treasury yield, which is used to price 30-year mortgages, rose to its highest level since January 2025, Japan's benchmark 10-year bond yield topped 3% for the first time since 1996, and Germany's 10-year Bund yield hit the highest point in 15 years.
A breakdown of those yields suggests the latest move is being driven, at least in part, by "real," inflation-adjusted yields — not inflation expectations or the murkier "term premium." That could make these increases sticky.
JAMIE MCGEEVER, ROI Markets Columnist: The marginal buyer in the $29 trillion Treasury market has changed — and this could make the world's biggest, most liquid market more volatile. While China and other major central banks have shed their Treasury exposure in recent years, domestic "fast money" — including hedge funds and speculators — has increasingly been taking their place. Hedge funds now own some $2.6 trillion of all Treasuries outstanding, more than 8% of the market.
This means conservative, long-term, price-insensitive investors are being replaced by yield-sensitive, nimble private-sector investors with shorter time horizons and often quite a bit of leverage.
Right now, as Treasuries and global sovereign bonds undergo their heaviest selloff in decades, it is worth asking whether changes in the ownership structure of the U.S. bond market increase the chance that an "accident" turns a correction into a crisis.
