What happened
The yield on UK 10-year government bonds, known as gilts, climbed to 5.4107%, according to market data cited in a brief report.
That level marks the highest for the benchmark yield since July 2007.
The move represented an increase of roughly 6 basis points within the day.
Why it matters
Long-term government bond yields are a key reference point for borrowing costs across an economy, so a rise to a multi-year high suggests investors are demanding more compensation to hold UK government debt.
Because the source material gives only the yield level and the daily move, the precise drivers behind the increase are not established here; the significance lies in the fact that the yield has reached a threshold not seen in nearly two decades.
