For months, bond investors had been settling into a comfortable story. Inflation was easing, central banks were mostly done tightening, and rate cuts felt like the next chapter.
Then oil surged, the Strait of Hormuz became an economic fault line, and that calm narrative cracked. Now Europe’s bond market is relearning an old lesson. When energy goes wild, everything else gets nervous fast.
Eurozone government bonds sold off again on Monday as investors reacted to the inflation shock coming from the widening war in the Middle East. Germany’s 10-year Bund yield rose 2.3 basis points to 2.886% after earlier hitting its highest level in a year, while the more rate-sensitive two-year German yield jumped 8.6 basis points to 2.393%, its highest since September 2024.
The move reflected a market that has stopped treating sovereign bonds as a classic safe haven and started treating them as inflation casualties. With traffic through the Strait of Hormuz disrupted and crude climbing to its highest level since 2022, traders are more focused on what higher energy costs could do to inflation than on the usual safety trade.
Eurozone inflation expectations climbed to 2.25% in money markets, their highest since July 2024. That has sharpened nerves at the European Central Bank, with investors starting to consider the possibility that the next move might not be a cut at all.
But while Bunds were under pressure, gilts were taking the bigger hit. Two-year gilt yields surged as much as 37 basis points before paring the move, and were still heading for their biggest one-day jump since the Liz Truss-era chaos of September 2022. Sterling fell 0.8% to $1.331, putting it on track for its biggest one-day drop in more than a month.
Markets have now priced out Bank of England rate cuts this year and are instead attaching a meaningful chance to a quarter-point hike by December. Before the conflict, traders had been leaning the other way. The reversal has been fast and ugly.
The United Kingdom is being treated as especially vulnerable to an energy-price shock because of its dependence on imported energy and the fragility of its public finances. Lloyds estimated that a roughly 2.5 percentage-point inflation shock could wipe out the government’s fiscal headroom even before any new cost-of-living support measures.
There was at least one attempt to calm the mood. A French government source said G7 finance ministers would discuss a possible joint release of emergency oil reserves. That helped steady some nerves, but not the broader message. Oil above $100 changes the mood everywhere.

This is what happens when the market realizes inflation is not gone. It is just lurking offstage, waiting for an energy shock to drag it back into the spotlight.
The key shift here is not just that yields are rising. It is why they are rising. Normally, a war this dangerous might send investors sprinting into government debt. Instead, they are hesitating, or outright dumping bonds, because the inflation hit from higher oil and gas prices looks more immediate than the haven appeal. That is a nasty signal for central banks. Geopolitics is no longer just a growth scare. It is a policy problem.
And the UK looks like the easiest target. Britain has a market that is especially sensitive to inflation surprises, a central bank that was already walking a narrow line, and public finances that do not leave much room for generous rescue packages. So when oil spikes, gilts do not just wobble. They start having bad memories.
That is why 2022 keeps hovering over this story. Nobody is saying this is another Truss crisis. But markets have memory, and gilts tend to catch the worst of it when energy prices surge and fiscal vulnerability enters the conversation. Investors do not need a full-blown panic to demand a higher risk premium. They just need a reason to worry.
The euro zone has a slightly different problem. Bunds and other core debt are also selling off, but more in the classic higher-inflation, higher-yields way. The ECB can still argue that short-term energy spikes are temporary. The trouble is that policymakers said similar things after Russia’s invasion of Ukraine, and that episode did not end especially well. Markets are less willing to take “look through it” on trust this time.
The bond market had spent months drifting into a soft-landing daydream. Now it is being reminded that the world still knows how to throw lit matches into the macro tinderbox.
If oil pulls back and Hormuz disruption eases, yields could stabilize and central banks may get to keep their wait-and-see stance. But if energy stays elevated, inflation expectations will keep creeping higher and markets will push harder against the whole 2026 easing story.
For the UK, that would be especially painful. Gilts have already become the market’s preferred way to express anxiety about inflation, fiscal stress, and policy confusion all at once. If oil stays hot, traders may keep pressing that trade.
And if they do, the Bank of England could find itself in the familiar and deeply uncomfortable position of having to sound hawkish just as growth starts to weaken. That is the kind of setup bond markets love to punish first and analyze later.
