# US 10-year Treasury yield reaches 5.34%, the highest since 2002, as the bond sell-off raises borrowing costs for junk-rated companies

The euro fell to a 17-month low on French debt worries, and Banque de France governor Emmanuel Moulin warned that France's annual interest bill could reach €100 billion by 2028 or 2029.

US government bonds fell again on Monday. The 10-year and 30-year yields each rose at least 7 basis points (hundredths of a percentage point), to 5.34% and 5.7%. [Bloomberg reported](https://www.bloomberg.com/news/articles/2026-10-05/treasuries-slump-pushes-long-end-yields-to-fresh-24-year-highs) that both are the highest since 2002, and that the move extends a slide that has now lasted a month. [CNBC reported](https://www.cnbc.com/amp/2026/10/05/treasury-yields-bonds-fed-rates.html) that traders were weighing new economic data before Wednesday's release of the minutes of the Federal Reserve's September meeting. [Tickmill's market outlook](https://www.tickmill.com/blog/daily-market-outlook-october-5-2026) describes that meeting as the one at which the Fed raised rates. The selling was concentrated in long-maturity bonds. Two- and three-year yields edged lower.

Corporate borrowers are paying more as well. The [Financial Times reports](https://www.ft.com/content/7c7ccb82-2973-47af-ad9b-b469c6ea0048?syn-25a6b1a6=1) that the Treasury sell-off has begun to raise borrowing costs for junk-rated US companies, meaning those rated below investment grade. These firms have the least cash to absorb higher refinancing rates. The government has already tried to hold down long yields, and that effort failed. Last week, yields [rose sharply](https://www.cnn.com/2026/10/01/business/bond-market-treasury-yields) one day after Treasury Secretary Scott Bessent announced larger buybacks of long-dated debt.

Chinese financial media give a fuller list of causes than most US coverage. [Wallstreetcn](https://wallstreetcn.com/articles/3782779) and other mainland financial outlets name four drivers: high oil prices that raise inflation expectations, strong data that support expectations of further Fed hikes, worries about US fiscal sustainability, and a surge in corporate bond issuance. From the perspective of the Austrian school of economics, the last two causes matter most. Investors are demanding more compensation to hold long-term claims on a government that keeps borrowing. A central bank buying back debt does not change how much debt there is.

Europe faces the same problem. The [Financial Times morning briefing](https://www.ft.com/content/1d152b5b-decb-41c3-a197-8de1d1ca26fc?syn-25a6b1a6=1) led with Moulin's warning on rising rates. [He said](https://www.archyde.com/banque-de-france-governor-warns-france-faces-threat-of-rising-interest-rates/) that France faces a progressively tighter squeeze from higher borrowing costs if parliament does not pass a budget that cuts the deficit. The government's 2027 draft budget proposes €43 billion of spending cuts and tax increases to bring the deficit down to 5% of gross domestic product, from an expected 5.4% this year. The government has no majority in the National Assembly, [so the bill's path is uncertain](https://www.indexbox.io/blog/bank-of-france-governor-warns-france-must-act-to-avert-sovereign-debt-crisis-ahead-of-2027-election/). The euro [fell to a 17-month low](https://www.cnbc.com/2026/10/05/dollar-holds-firm-as-french-fiscal-woes-keep-euro-on-back-foot.html). The dollar index rose 0.26% to 102.19 after touching 102.53, and the dollar gained 0.15% to 158.06 yen.

[The Economist argues](https://www.economist.com/finance-and-economics/2026/10/05/the-bond-market-sell-off-is-helping-the-dollar) that the sell-off is supporting the dollar, but that the currency's strength is less reliable than in past episodes. US stocks did not respond to the bond market. [Globes reported](https://www.globes.co.il/news/article.aspx?did=1001558504#utm_source=RSS) that the Nasdaq Composite closed at a new high, led by large technology stocks, "despite bond yields continuing to climb," while Asian markets opened mixed on Tuesday.

## What this means

Several channels are at work. A higher term premium (the extra yield investors demand for holding long-dated bonds) raises refinancing costs for leveraged companies, for the private credit behind the artificial-intelligence buildout, and for indebted governments such as France. A stronger dollar tightens funding for emerging-market borrowers who owe dollars. The market has largely priced the move in Treasuries. It has not priced the move in equities, which are trading near recent highs even though risk-free long yields exceed 5%. The consensus treats the dollar as the automatic winner. The Economist's caveat fits the April 2025 episode, when Treasuries and the dollar fell together because investors were questioning US fiscal policy itself. The closest precedent is the 1994 bond rout. Fed hikes and fiscal doubts pushed long yields up sharply that year, and the damage appeared months later in Orange County's bankruptcy and Mexico's peso crisis. The likelier outcome is that within weeks, Washington and Paris add more balance-sheet measures, such as bigger buybacks or a shift toward shorter-term issuance, and that long yields keep rising anyway while oil stays near $100. That would push the strain into high-yield credit (junk bonds) and weaker sovereigns over the next few months. The read is wrong if the Fed minutes signal no further hikes and the 10-year falls back below 5% even though the deficit outlook has not improved.

## What to watch

- Whether Wednesday's Fed minutes show officials considering another hike. That would confirm that short and long rates are rising together, not just the long end.
- Whether the US Treasury enlarges its debt buybacks or cuts long-bond issuance at its next quarterly refunding announcement, its schedule for auctioning new debt. Either step would show the government turning again to balance-sheet tools.
- The French National Assembly's first votes on the 2027 budget. A failure would likely widen the gap between French and German borrowing costs and weaken the euro further.
