UK government borrowing costs rose to multi-year highs as inflation concerns and fiscal uncertainty ahead of the October 28 budget pushed gilts (UK government bonds) higher. LSEG data showed the 30-year gilt yield reaching 5.904%, its highest level in more than 28 years, while the 10-year yield climbed to 5.255%, the highest since 2008. Broader strength in global sovereign bond yields also reinforced the move, eToro global market strategist Lale Akoner said. Higher yields can improve income for bond investors, but they also raise pressure on mortgages, interest-rate-sensitive equities and government finances.
