LONDON, July 9 (Reuters) - Sterling jumped against the dollar and euro on Thursday after the Bank of England kept its quantitative easing target unchanged, surprising markets which had expected an expansion of the scheme.

The BoE left its asset buying programme total at 125 billion pounds, which is on track to hit later this month. Markets had expected the central bank to expand the total by 25 billion pounds, which would have allowed the central bank to pump money into the economy until August when it publishes new quarterly economic forecasts.

The central bank left key interest rates unchanged at 0.5 percent, as widely expected.

Sterling jumped to a session high of $1.6272 GBP=D4 from around $1.6170 shortly before the announcement. By 1150 GMT, it was up 1.1 percent at $1.6251.
