Global bond markets faced sharp turbulence at the start of the fourth quarter, driving long-term government yields higher across Japan, Australia, the Netherlands, France, and Germany, bnr.nl reported. The 10-year US Treasury yield climbed to 5.34%, marking its highest level since 2002 and recording its largest quarterly jump this century with a rise of nearly 90 basis points in the third quarter, according to MarketScreener Nederland.
The upward pressure on yields stems from multiple economic factors, including climbing mortgage rates in the United States and Europe that have forced institutional investors to adjust their portfolios. As higher borrowing costs require consumers to take longer periods to pay off mortgages, pension funds and insurance companies must hedge that increased risk by selling portions of their government bond holdings, bnr.nl reported. This selling pressure triggers a self-reinforcing upward spiral in bond yields worldwide. Meanwhile, MarketScreener Nederland noted that similar decades-high borrowing costs hit French 10-year bonds and pushed British 30-year financing costs above 6% for the first time since 1998. At 13:23 New York time, the S&P 500 gained 0.1 percent while the Nasdaq 100 stood 0.3 percent higher.
France plans savings to combat surging debt
In France, Prime Minister Sébastien Lecornu presented a 2027 recovery budget aimed at delivering 54 miljard euros in total savings while raising alarms over the surging cost of financing the national debt. The French state debt stands at approximately 3,6 biljoen euro—roughly 119 percent of gross domestic product—and is projected to climb to 121.7 percent by 2027, more than double European Union targets, bnr.nl reported.

Private Investors Step In as Yields Hit 5 Percent
With a 5% yield now available on U.S. government debt, private domestic investors have expanded their market share from 30% to 50% following the withdrawal of the Federal Reserve and other official buyers, Belegger.nl reported. Janus Henderson Investors portfolio manager James Briggs stated that higher yields can successfully attract fresh capital from cash holdings and alternative investments to absorb the expanding public debt. Deutsche Bank estimates that a positive total return remains possible over a 12-month horizon provided interest rates stay beneath 5.5%.
Wall Street Recovers Ahead of Employment Data
Strong demand for government bonds helped Wall Street indexes close higher on Thursday, easing inflationary concerns tied to rising oil prices as Brent crude held above $100 per barrel, Headliner.nl reported. The yield on the 10-year Treasury retreated seven basis points to 5.21% as the broader bond sell-off eased. Economists surveyed by Headliner.nl anticipate that September nonfarm payrolls rose by 88,000 jobs while unemployment held steady at a one-year low of 4.1 percent.
Interest payments exceed global investment in AI
Major economies now spend more on interest payments than the world invests in AI, defense, or clean energy, according to the Institute of International Finance. The American debt burden has surpassed 40 trillion dollars, while debt as a percentage of economic output stands at 100% or more in most major G7 economies, with Germany as the exception. Federal Reserve Bank of Minneapolis President Neel Kashkari noted during a Bloomberg Television interview, I don’t know the answer to that.
Brian Therien of Edward Jones noted in market commentary, A strong labor market also gives the Fed more flexibility to target inflation.
What caused US Treasury yields to rise?
