Government bond markets remain under pressure as rising energy prices revive inflation concerns and increase expectations that major central banks will keep interest rates higher for longer.

The benchmark 10-year US Treasury yield briefly touched 5.011% on Monday, according to Dow Jones Market Data, before falling back below 5%. The level was the highest since October 2023.

The yield crossed the psychologically important 5% threshold as higher government borrowing, resilient economic growth and heavy corporate debt issuance linked to artificial intelligence investment compounded pressure on US bonds. Yields move inversely to bond prices.

Rising Treasury yields can feed through to mortgages, corporate loans and other forms of credit, potentially slowing economic growth. They can also make bonds more attractive relative to highly valued equities.

The latest rise followed the US Treasury’s previously announced expansion of its bond-buyback programme. Last week, it offered to purchase up to $6 billion of debt maturing in 10 to 20 years – three times the previous operation’s size.

The yield on the 30-year US Treasury bond, meanwhile, remained close to its highest level since 2007.

The sell-off has also spread across Europe. France’s 10-year government bond yield rose to 4.50% on Monday, while the equivalent Italian yield reached around 4.40%.

Germany’s benchmark 10-year Bund yield climbed as high as 3.538%, according to Dow Jones Market Data, its highest level in 15 years.

Energy prices are a major source of pressure. Brent crude rose to around $107 a barrel on Tuesday morning, while US West Texas Intermediate traded close to $103, as attacks on Saudi energy infrastructure and shipping in the Gulf intensified concerns about supplies through the Strait of Hormuz.

The European Central Bank raised its deposit rate by 25 basis points to 2.5% last week and warned that inflation could remain above its target for an extended period. Markets are pricing in at least one further ECB increase this year.

Attention now turns to three major central-bank decisions. The US Federal Reserve announces its decision on Wednesday, followed by the Bank of England on Thursday and the Bank of Japan on Friday.

A Reuters poll found that 85% of economists expected the Fed to raise rates by 25 basis points, while money markets placed the probability of an increase at around 93%.

The BoE is widely expected to leave rates unchanged. Economists surveyed by Reuters unanimously forecast no change, although some analysts have warned that a surprise increase cannot be ruled out. The BoJ is widely expected to raise borrowing costs.

Borrowing costs across some of Europe’s biggest economies have surged to their highest levels in more than 15 years, as a renewed sell-off in global bond markets gathers pace.

The global bond rout pushed Germany’s benchmark borrowing costs to a 15-year high on Tuesday, with France, Italy and the Netherlands all seeing similarly steep rises.

Germany’s 10-year Bund climbed above 3.36% on Tuesday, according to Trading Economics. Later, the yield went down a bit and traded at around 3.34%.

Bond yields move inversely to prices. When investors sell bonds, prices fall, and because a bond’s fixed interest payment becomes worth more relative to that lower price, the effective yield rises.

In short — the more bonds get sold, the more it costs governments to borrow.

Sovereign debt came under renewed pressure as rising oil prices and increasingly hawkish signals from major central banks reinforced bets that interest rates will stay higher for longer.

The yield on Germany’s 30-year Bund surged above 3.84%, also its highest level since 2011. The French 10-year OAT yield rose to its highest level since November 2008, trading slightly above 4.215% at around 10.45 CEST on Tuesday. The equivalent Italian yield was trading slightly lower at 4.188 at the same time.

At the same time, the Dutch 10-year government bond yield increased to 3.43%, its highest level since May 2011. Spain’s 10-year yield climbed above 3.80%, its highest level since November 2023.

Investors are concerned that rising energy prices will fuel inflation around the world, potentially prompting interest-rate increases by central banks in the US, Japan and the eurozone, among others.

These concerns were reinforced in the eurozone on Tuesday morning, as the latest flash inflation data from Eurostat showed that energy prices were 14.3% higher than a year earlier. This helped push eurozone inflation to 3.3% in August, up from 2.9% in July. This is significantly above the ECB’s 2% target.

The central bank is due to hold its next monetary policy meeting next week, and most investors are betting on a 25-basis-point rate hike.

Leo Barincou, senior economist at Oxford Economics, said: “With inflation still accelerating, the ECB is all but certain to hike at next week’s meeting, in line with our expectations.”

Looking at the largest European economies, analysts say Germany’s Bund has moved largely in line with global benchmarks, while France faces an additional risk premium because of its political and fiscal outlook.

French 10-year borrowing costs have exceeded Italy’s for much of the summer, as France increasingly replaces Italy as the main focus of European debt concerns.

According to the IMF, France’s gross government debt is projected to reach 118.4% of GDP this year and 120.5% in 2027. France currently has the third-highest debt-to-GDP ratio in the EU, after Greece and Italy.

The Banque de France expects the budget deficit to reach 5.2% of GDP this year. Difficult budget negotiations ahead of the 2027 presidential election have raised doubts about the government’s ability to reverse this trend.

Robert Timper, BCA’s chief fixed-income strategist, previously told Euronews Business: “We have held the view for some time that France is the country in the euro area with the most unsustainable fiscal outlook, and its borrowing cost should reflect that.”

“To get back to a sustainable fiscal path, France needs to do substantial reforms, which will be unpopular as they will curtail welfare spending,” Timper said. “A large political majority is therefore necessary for such reforms, or a bond market riot will force reforms.”

Global bond sell-off

Expectations of persistently high inflation and rising borrowing costs also pushed the yield on 10-year US Treasuries to its highest level since January 2025. The yield on the 10-year Treasury was trading at around 4.78% on Tuesday.

In the US, higher energy prices have added to already stubborn inflation, which remains well above the Federal Reserve’s 2% target. Inflation has weighed on household spending and consumer confidence, complicating the Fed’s decisions on interest rates.

According to Bloomberg, traders raised the probability of a September US rate hike to about 70%, extending a repricing that began last week when Federal Reserve Chair Kevin Warsh doubled down on a pledge to tame inflation.

The sell-off also spread to Asia, where Japan’s benchmark 10-year government bond yield reached 3.00% for the first time since 1996.

Government bonds have traditionally been seen as safe-haven assets during periods of uncertainty.

That role is being tested as investors become increasingly concerned that global conflicts and higher energy prices could produce a prolonged period of stagflation — a combination of high inflation and weak or zero economic growth.
