Bond markets could force Rachel Reeves ‘to do a secondary budget’, City investor warns

David Zahn of Franklin Templeton said bond yields could rise in response to chancellor's fiscal plans and government would have to react

The bond markets could force Rachel Reeves to deliver a second budget if investors are disappointed by the chancellor's fiscal plans next week, a City investor has warned.

David Zahn, the head of European fixed income at Franklin Templeton, said the biggest risk from the budget on 26 November was that Reeves disappoints", leading to a sharp rise in bond yields - the interest rate on UK government debt.
