Banks are once again leading the FTSE 100 gains in early trading, after a number of stocks soared upwards of 10% yesterday on the relaxing of Basel III rules.
In early trading, London's leading index of shares was up 14.95 points, or 0.28%, to 5,380.62 points.
RBS leads the charge early, up 2.78% to 51.75p - while Barclays and Lloyds are 2.12% and 1.2% higher respectively.
Banks are extending gains from Tuesday, when they were boosted by strong earnings from UBS and the new Basel III capital rules proving less stringent than feared. They had also gained on Monday after the vast majority of banks passed stress tests.
Britain's top share index hit a 10-week closing high yesterday, as a buoyant banking sector countered weak US consumer confidence data.
In the US, strong earnings from DuPont helped drive the Dow Jones Industrial Average higher, but the Standard & Poor's 500 fell as a consumer confidence reading hit its lowest level since February.
The Dow Jones Industrial Average ended just 0.1% higher to 10537.69. DuPont was the DJIA's best performer, up 3.6%.
However, the DJIA's gain was limited by its consumer-related components, which fell following data showing US consumer confidence declined again in July, in a painful reminder of the divergence between strong earnings and weak economic data.
Leading Japanese shares climbed sharply overnight on strong corporate results and a weaker yen.
The main Nikkei index closed up 256.42 points, or 2.7%, at 9,753.27.
