The yield on the UK’s 10-year gilt climbed to about 5.08% — its highest level since 2008. That rise pushed government borrowing costs higher and forced investors to reassess rate expectations ahead of the Bank of England’s policy meeting this week, after a sell-off tied to Middle East conflict and disruptions around the Strait of Hormuz lifted energy prices and inflation fears.

Sell-off driven by Middle East tensions

Investors pushed yields higher as the US-Iran conflict intensified and shipping through the Strait of Hormuz became effectively restricted. Higher crude prices fed into expectations of a renewed inflation shock, making government bonds less attractive. Brent crude trading above $110 a barrel put upward pressure on UK import prices and inflation expectations.

Market commentary linked recent price action to diplomatic developments in Washington; some traders said moves by the US administration failed to calm markets, prompting widespread government bond selling and a drop in bond prices that pushed long-dated yields higher.

How yields moved

Trading snapshots showed the 10-year gilt yield near the 5% mark, around 5.081% on one reading — the highest level since 2008. The move reflected a combination of higher inflation expectations and stronger odds of further central-bank tightening, which lifted the expected path for policy and put upward pressure on gilt yields.

Voices from the market and the city

"Markets feel more panicky this week, and Friday’s price action suggests that investors are losing faith in Donald Trump’s ability to end this war and reach a deal with the Iranians," said Kathleen Brooks, research director for the UK at XTB. Her comment captured the mood: political moves in Washington can shift global risk sentiment and the pricing of UK debt.

City traders worry the Bank of England could be forced into a tougher stance than some peers to keep inflation expectations anchored, a concern reinforced by the recent jump in energy prices and memories of the 2022 inflation spike.

Domestic politics and fiscal pressure

Higher yields raise interest costs on new issuance and refinancing, adding a direct burden to public finances. Economists warn rising yields will complicate fiscal choices for the chancellor, Rachel Reeves, amid pressure to support households facing cost-of-living strains.

Political distractions — including a critical parliamentary vote tied to a diplomatic appointment — add domestic uncertainty while markets reassess UK fiscal plans. These risks, combined with the global sell-off, increase the premium investors demand to hold UK government debt.

Policy dilemma for the Bank of England

The Bank of England meets this week with policymakers weighing elevated inflation pressures from energy markets against signs of slowdown in the jobs market and overall growth. Policymakers must weigh higher energy-driven inflation risks against weakening labour-market and growth signals when setting policy.
