European bond yields edged lower on Friday after a severe sell-off earlier in the week, while rising US Treasury yields pushed American mortgage rates to 7%. The market move highlights growing concern about inflation, higher oil prices, government borrowing and political risk in France.
The modest recovery in European government bonds came after one of the sharpest market routs in years. Investors remain cautious as borrowing costs rise on both sides of the Atlantic and traditional safe-haven assets become less reliable during periods of economic uncertainty.
European bond yields retreat slightly after heavy losses
The yield on France’s 10-year government bond, known as the OAT, was trading at about 4.67% on Friday morning, compared with approximately 4.70% earlier. Germany’s 10-year Bund yield also eased, moving to around 3.59% from 3.61%.
Although the changes were small, they followed a major rise in borrowing costs during the week. The spread between French and German 10-year yields exceeded 110 basis points, reaching its widest level since the eurozone debt crisis of 2012. This spread is closely watched because it reflects the additional premium investors demand to hold French debt rather than German government bonds.
France has faced increased market pressure because of concerns about its public finances and the political outlook ahead of the 2027 presidential election. Those concerns were intensified by a downgrade from Scope Ratings. The cost of insuring French government debt against default has also risen to its highest level in almost a decade.
US Treasury yields put pressure on mortgage borrowers
The larger move took place in the United States, where Treasury yields climbed to multi-decade highs. The 30-year Treasury yield reached about 5.5%, its highest level since 2004, while the 10-year yield rose to levels last seen in 2007.
Higher energy prices have added to fears that inflation may remain persistent. At the same time, investors are assessing the effect of rising government debt and the possibility that central banks may keep interest rates higher for longer.
US households are already seeing the impact. The average 30-year mortgage rate reached 7% during the week, roughly one percentage point above its level before the Iran war began and the highest since Donald Trump returned to the White House in January 2025.
US mortgage rates are influenced by movements in longer-term Treasury yields, although lenders also take account of funding costs, credit risk and market conditions. The increase therefore matters not only to prospective homebuyers but also to the wider housing market and consumer spending.
Why bonds and shares are falling together
Government bonds traditionally attract investors when stock markets become volatile. Their reputation as a safe haven is weaker, however, when inflation and energy shocks are pushing interest rates higher.
Nick Saunders, chief executive of investment platform Webull UK, said the simultaneous weakness in bonds and equities reflected inflationary pressure. Energy costs and geopolitical tensions can raise prices while slowing economic growth, creating an environment in which investors are reluctant to move into fixed-income assets.
The pattern has similarities with the economic conditions of the early 1970s, when energy shocks and wage pressures contributed to higher bond yields and falling share prices. Today’s economies are less dependent on oil than they were then, and labour markets have more capacity to absorb inflationary pressure, but the comparison illustrates why markets are unsettled.
Investors may look to inflation-linked bonds, gold and other assets that are less closely tied to equity markets. However, abandoning government bonds altogether could carry risks if inflation pressures ease and interest rates eventually fall.
Could higher rates create fiscal pressure in Europe?
Oxford Economics has taken a more measured view of the market turmoil. Its economists Ricardo Amaro and Daniel Kral said the rise in interest rates could be temporary, reflecting a reassessment of how monetary policy may respond to higher energy prices.
Many European governments may be able to manage higher borrowing costs because their debt has a relatively long average maturity. That structure means changes in market yields do not immediately affect the entire stock of outstanding debt.
France and Italy are considered more exposed than some other eurozone countries. In a severe scenario involving sustained higher interest costs, both could require fiscal tightening of more than one percentage point of gross domestic product to offset the increase. Spain, Greece and Portugal are viewed as better positioned to absorb the pressure.
What the bond market move means for Europe
The latest market action does not by itself indicate a new eurozone debt crisis. Friday’s decline in yields suggests some stabilisation after the week’s losses, but investors remain focused on several risks:
- Whether higher oil prices keep inflation elevated.
- How long central banks may need to maintain restrictive monetary policy.
- Whether government debt levels will require tighter national budgets.
- How political uncertainty could affect France’s borrowing costs.
- Whether weaker growth and higher rates will weigh on businesses and households.
For Ireland and other eurozone economies, market borrowing costs can influence government financing, bank funding and lending conditions. The European Central Bank does not directly set mortgage rates for households, but its policy decisions and wider bond-market movements can affect the rates commercial banks offer.
What happens next?
Markets will continue to track energy prices, inflation data, central-bank signals and fiscal announcements from major European governments. A sustained decline in yields would suggest that investors see the recent interest-rate shock as temporary. Further increases, particularly in France or Italy, could renew concern about debt sustainability and budget choices.
The immediate takeaway from this episode is that bonds are not automatically providing protection when inflation and geopolitical risks are rising. European bond yields have eased modestly, but the underlying pressures affecting government borrowing and household finance remain in place.
