Bond market rout deepens as inflation fears keep rising
Good morning, and welcome to our rolling coverage of business, the financial markets and the world economy.
The bond market is doing its traditional job of intimidating governments – and investors – as fears of an inflation shock from the Iran war grow.
The bond sell-off which gripped the markets last week is continuing this morning, driving up governments’ cost of borrowing from Tokyo to Washington DC.
With the strait of Hormuz still largely closed, the prospect of a lengthy period of shortages of oil and gas, which would push up costs of energy, transport and food, is growing.
Last Friday, global government borrowing costs soared – with the yield (or interest rate) on Japan’s 30-year bond hitting 4% for the first time.
US and eurozone debt also suffered, as traders bet that central banks will fored to raise interest rates, or abandon hopes of rate cuts, to stem the inflationary waves hitting the global economy.
As analysts at ING put it:
First, even if the war were to end tomorrow, energy prices may not fall as far as many expect. Significant drawdowns in oil inventories are likely to keep upward pressure on prices for some time yet.
Second, natural gas prices currently look too low. There is meaningful upside risk if disruptions persist into the third quarter, particularly as competition intensifies between Asian and European buyers for LNG.
It’s a reminder that, for all the political noise, its energy prices will remain the dominant force for central banks. It’s why we’re expecting rate hikes from the Bank of England and European Central Bank in June, and why we no longer expect a Federal Reserve rate cut until December.
This morning… US and Japanese government bonds have extended their losses, pushing up yields (which rises when bond prices fall.)
Benchmark 10-year U.S. Treasury yields jumped to their highest since February 2025 this morning at 4.6310%.
Yields on the 30-year Japanese government bond hit the highest level on record at 4.200%, while while the 10-year yield reached its highest since October 1996 at 2.800%.

Key events
Fears of ‘stagflationary shock’ hitting bonds
The jump in the oil price today has “exacerbated fears about a stagflationary shock” and pushed global bond yields even higher this morning, says Jim Reid of Deutsche Bank.
He told clients:
Admittedly, if you look over the entire conflict, bond yields have moved in lockstep with oil, and Friday doesn’t look too anomalous. However, if you zoom in a bit, then yields have shifted from being broadly in line with the current price of oil to looking a bit high relative to it. That suggests some evidence of a small decoupling on Friday.
With these end-of-week moves, 30yr US yields hit their highest level since 2007, 30yr Japanese yields their highest since their introduction in 1999, 30yr gilts reached levels last seen in 1997, and 30yr German yields returned to 2011 levels.
China heading for slowdown after April’s economic data disappoints
Weak economic data from China is also worrying investors this morning.
Chinese factory output growth slowed to 4.1%, year-on-year, in April, down from 5.7% in March, data from the National Bureau of Statistics (NBS) showed today. That was despite a jump in exports as customers tried to stockpile goods to avoid supply disruption from the Iran war.
Retail sales growth slowed to just 0.2% in April – the weakest reading since December 2022 – down from 1.7% in March.
China’s fixed asset investment declined – to a fall of 1.6% year-on-year in January-April, down from a 1.7% rise in January-March.
Lynn Song, ING’s chief economist for Greater China, says:
It suggests a steep drop-off of investment in April as geopolitical uncertainty may have weighed on investment decisions.
This disappointing April economic activity suggests growth will decelerate in the second quarter, after the first quarter comfortably beat expectations, Song adds.
Oil at near-two-week high
The oil price has risen this morning, which will put more pressure on government bond prices.
Brent crude is up 1.77% at $111.16 a barrel, its highest level in nearly two weeks.
Anxiety over the Iran war rose today after a nuclear power plant in the United Arab Emirates was attacked over the weekend.
Tony Sycamore, analyst at IG, says:
These attacks serve as a pointed warning: any renewed US or Israeli strikes on Iran could quickly trigger more proxy assaults on Gulf energy and critical infrastructure.
French finance minister Roland Lescure has revealed that G7 finance ministers will discuss the situation in the bond markets when they meet in Paris today.
Lescure argued that global bond markets are undergoing a correction rather than a collapse, adding:
“We are no longer in a period where public debt is not a subject.”
Burnham: I support the fiscal rules
The global bond market sell-off means this is a bad time for UK politics to be gripped by a leadership crisis.
British government debt got hammered on Friday, as Keir Starmer’s premiership circled the plughole and likely challenger Andy Burnham limbered up to return to parliament by contesting a by-election in Makerfield, in the North West of England.
The yields on 30-year UK debt hit their highest since 1998 last week, with 10-year gilt yields the highest since 2008.
Those losses came amid warnings that if Starmer is replaced, the Labour government might shift towards higher spending and borrowing, cutting loose from the fiscal rules designed to reassure the bond markets.
However, Burnham tried to calm concerns that he might drive up spending. Over the weekend he told ITV:
“I support the fiscal rules, there needs to be a plan to get debt down.”
That pledge might provide some support for UK bonds today….
