London midday: Stocks edge higher as BoE ups QE

- BoE increases QE, maintains Bank Rate- ECB expected to cut refi rate to 0.75 per cent- GKN jumps higher after 633m-pound Volvo Aero purchaseThe Footsie was registering moderate gains in morning trade on Thursday as investors hoped that the Bank of England would inject more stimulus into the subdued UK economy; the central bank did just that with the Monetary Policy Committee (MPC) announcing additional quantitative easing at midday. The Footsie, trading around the 5,700 mark this morning, has not closed above that level since May 3rd.As expected, the MPC maintained the Bank Rate at 0.5% and decided to ramp up its asset purchase programme by £50bn to £375bn. "Against the background of continuing tight credit conditions and fiscal consolidation, the increased drag from the heightened tensions within the euro area meant that, without additional monetary stimulus, it was more likely than not that inflation would undershoot the target in the medium term. The Committee therefore voted to increase the size of its programme of asset purchases," the MPC said.Meanwhile, the European Central Bank (ECB) is widely expected to cut the refinancing rate from the current level of 1.0% this afternoon. Gerhard Schwarz, head of Equity Strategy at Baader Bank, said: "The most likely outcome in our view is a 25 basis point cut. A bigger cut would increase pressure on the ECB to move towards 'unconventional' stimulus - something the ECB has been very reluctant to do recently. So with the refi rate standing at 0.75% the ECB could still argue to have some firepower left."
