World stocks kept a firmer tone on Thursday after the Bank of England surprised the market by launching a fresh round of monetary easing this month, before cutting gains as the European Central Bank left interest rates on hold.
The euro hit the day's low and German government bonds rose after the ECB held interest rates at 1.5 percent, disappointing some who had expected a cut in borrowing costs this month.
Such expectations grew after the Bank of England pledged to buy a bigger-than-expected 75 billion pounds in assets to bolster the UK economy -- a move that pushed sterling to a 14-month low against the dollar.
Investors are now focusing on ECB President Jean-Claude Trichet's news conference at 1230 GMT -- his last, and at which he is expected to announce a set of fresh liquidity measures to help banks.
Growing hopes that policymakers would take coordinated steps to support European banks, under threat from the impact of a possible Greek debt default, kept the underlying tone positive for risky assets.
European Commission President Jose Manuel Barroso proposed a coordinated recapitalization of banks to restore confidence, while the European Banking Authority said it was examining the resilience of lenders' capital positions.
Optimism over near-term policy measures -- both from politicians and central banks -- are helping investors to take a break from a sell-off triggered by growing concerns about the damage to the banks from any Greek sovereign default.
It's a good injection of capital. We now just need to see a coordinated effort from the rest of Europe to sort out the recapitalization of European banks and it should form a decent base to move forward, said IG Index sales trader Yusuf Heusen.
It takes away quite lot of risk. This is positive for the market.
