Overview
- UK government bond yields, which jumped Tuesday to about 5.1% on the 10‑year and 5.8% on the 30‑year, are holding near multi‑decade highs.
- Oxford Economics says most of the rise since the Iran war reflects higher inflation expectations from the energy shock rather than domestic policy shifts.
- Political tension has added a premium after roughly 80 Labour MPs urged Keir Starmer to resign, and investors sold gilts and the pound.
- Higher yields raise debt‑service costs and could cut Chancellor Rachel Reeves’ fiscal headroom by about £6 billion, which may mean tighter public budgets or higher taxes.
- Bank of England policymaker Catherine Mann warned that heavy foreign ownership can amplify gilt swings, even as big buyers like Standard Life step in to pick up cheaper bonds.
