Oil above US$90 and a near US$40 trillion US debt pile drove 30-year yields to 2007 levels
Long-dated bonds already sitting in institutional portfolios repriced sharply this week as a global selloff carried 30-year borrowing costs to levels last seen in 2007.
The New York Times reported that the 30-year US Treasury yield reached 5.3 percent on Tuesday, with comparable bonds in Canada, Japan, Germany, and elsewhere trading at their highest yields in at least a decade.
A fast rise in yields erodes the market value of existing long-dated bonds held by banks, insurers, and pension funds, Reuters noted in an explainer on the selloff.
Institutions forced to sell before maturity can lock in losses, the outlet added, even though the securities repay face value if held to term.
Whether the markdown stays on paper or becomes realized depends on whether a portfolio can hold the position.
According to the same publication, Treasuries are the benchmark risk-free asset anchoring the pricing of mortgages, corporate bonds, emerging-market debt, private credit, and equity valuations worldwide.
Reuters also reported that a sustained rise in US yields can pull capital toward dollar assets, strengthening the dollar and tightening financial conditions abroad, making refinancing harder for lower-rated companies, indebted governments, and emerging-market borrowers.
On the corporate side, companies typically borrow at a Treasury yield plus a credit spread, Reuters reported, so rising benchmark yields lift corporate borrowing costs directly.
The pain concentrates among issuers bringing new bonds to market, refinancing, or carrying floating-rate loans while those that locked in low fixed rates years ago have more room.
Higher costs can also make capital-intensive projects such as data centres, energy infrastructure, and industrial expansion less attractive, Reuters noted, potentially curbing future investment and earnings growth.
The same publication reported that rising yields reduce the present value investors assign to future profits, a particular risk for high-growth technology names.
The outlet noted that equity damage may be limited when yields climb because the economy is strengthening and profits are improving.
The 30-year US Treasury yield eased more than 2 basis points to 5.285 percent on Tuesday after touching a 19-year high earlier in the session, CNBC reported, with the 10-year note at 4.706 percent.
The Wall Street Journal logged intraday peaks of 5.333 percent and 4.748 percent on the two maturities in European trade.
Several forces sit behind the move, Reuters reported: mounting government borrowing that markets must absorb, resilient economic growth, inflation risks from Middle East energy disruptions, and the potential for the US Federal Reserve to keep rates higher.
Questions about foreign appetite for US debt have grown, with some overseas investors showing signs of diversifying away from Treasuries, per the outlet, while heavy corporate borrowing for data centres and artificial intelligence (AI) investment has increased competition for investor capital.
“We believe the long-end has been subjected to death by a thousand cuts,” TD analyst Gennadiy Goldberg wrote in a research note quoted by Reuters, adding that low investor conviction could leave yields under sustained pressure in the near term.
Jonas Goltermann, chief markets economist at Capital Economics, told the same outlet the surge suggests investors are losing patience with fiscal profligacy, though he called it unsurprising given the fiscal outlook in several major economies.
Washington ran a budget shortfall of US$432.3bn in July, the widest single month since March 2021, CNBC reported citing Treasury data, with total government debt a hair below US$40tn.
Not every investor reads the move as a warning.
Pictet senior investment adviser Christopher Dembik told Reuters the firm is long duration and does not expect the current selloff to last, while the outlet noted that some bond investors see rising yields making the market attractive enough to support prices from here.
