UK Gilt Yields Near Multi-Decade Highs Pressure the FTSE 250

Britain's borrowing costs are sitting at levels not seen in decades, and that is starting to squeeze domestically focused stocks. Share Talk reports the 10-year gilt yield hit 5.527 percent in early October, its highest since July 2007, while the 20-year yield reached 6.00 percent and the 30-year touched 6.05 percent.

On 27 October the UK sold 4.5 billion pounds of five-year gilts at an average yield of 5.036 percent, the highest for that maturity at auction since 2008. Inflation is also a worry, with September CPI at 3.5 percent and the House of Commons forecasting it could rise above 4 percent in early 2027.

That matters for the FTSE 250, because LSEG research cited in the report says about 43 percent of its revenue is UK-exposed, making it more sensitive to domestic conditions than the FTSE 100. Higher yields mean pricier mortgages, loans and government debt, a combination that could keep pressure on British businesses and investors.
