REUTERS/Dado Ruvic/Illustration/LONDON, Sept 26 (Reuters) - British government bond prices collapsed on Monday, pushing yields to their highest in over a decade, amid speculation that the Bank of England might need to take emergency action after sterling hit a record low against the U.S. dollar overnight.
Two-year gilt yields rose as much as 54 basis points on the day to 4.533%, their highest since September 2008, and at 0754 GMT were 44 basis points up on the day at 4.43%.
Five-year gilt yields jumped more than 44 basis points to 4.503%, their highest since October 2008, while benchmark 10-year yields hit their highest since April 2010 at 4.215%.
