Why did UK mid-cap stocks hit a nearly one-month low on Wednesday?

UK mid-cap stocks hit a nearly one-month low on Wednesday due to surging UK gilt yields—reaching their highest since June 2008—driven by renewed inflation fears following fresh U.S.-Iran strikes in the Middle East, which triggered a global bond sell-off and pressured risk assets like midcaps.

What impact do rising gilt yields have on UK fiscal policy, according to market strategist Matthew Ryan?

According to Matthew Ryan, head of market strategy at Ebury, the rise in gilt yields 'will eat directly into the government's fiscal headroom', raising the risk of tax hikes in the autumn—even before accounting for any additional spending increases that Labour leader Burnham seems likely to pursue.
