WSJ: Britain’s Cost of Borrowing Rises

"Investors are demanding more these days in return for lending to the U.K. government. That’s bad news for Britain, which has a lot of borrowing to do — in the form of selling bonds". "Some worry that government bond yields could rise sharply next year, or even spike, hiking up Britain’s borrowing costs. Here’s why: For months now, the U.K.’s central bank has been buying mostly government bonds in a bid to pump up the economy. That is keeping bond prices artificially high and yields relatively low. The fear is that once Bank officials withdraw their hand from the market — which could possibly happen next year — yields may jump up".
