Bank of England's Mann warns a new shock could make foreign investors dump gilts

LONDON, May 13 (Reuters) - The ​growing ⁠role of price-sensitive international ​investors in buying British government debt in place of ​domestic ‌pension funds risks leading to greater volatility ⁠in borrowing costs, Bank of ⁠England policymaker Catherine ​Mann said on Wednesday.

On Tuesday, amid intense pressure on Prime Minister Keir Starmer, British 30-year ​bond ‌yields hit their highest since 1998 and 10-year borrowing costs rose to their highest since 2008.

"Although price-elastic investors ​can be an advantage in terms of the ‌level of interest rates, they are also more responsive to ‌changes in interest rates on account of domestic or global shocks," Mann said in ​the text of a speech to be given at ‌the London School of Economics.

"Hypothetically, if a new shock were to occur and ⁠weigh ⁠on investor confidence, these more ‌price-elastic international investors could respond by reducing their gilt ​holdings. ​The resulting volatility in yields could ‌be reflected in a persistent risk premium on gilts," she added.
