The banking sector is performing well today after a report from the Independent Commission on Banking (ICB).The ICB stopped short of recommending that banks that have investment banking arms should demerge those operations. Instead, it has recommended that banks' retail operations should be protected by a "firewall" from the investment banking division. Barclays, RBS and Lloyds are all firmer.GKN is higher, offsetting any negative impact sourcing from a Charles Stanley downgrade to 'reduce', from 'hold'. The engineer saw sales rise by 14% in the first quarter to £1.49bn.Also lower is outsourcing giant Capita, which has conditionally agreed to acquire public sector service provider Tribal's health and government divisions for £15.8m. A broker note by Nomura has done little to help the share price of airline giant IAG. The Japanese broker said that while the airline market is likely to adjust to the high oil prices with fuel surcharges and capacity decisions, "that adjustment lags the movement in the spot oil price and so there is near-term margin pressure when fuel rises sharply."---bcFTSE 100 - RisersBarclays (BARC) 308.50p +3.82%Royal Bank of Scotland Group (RBS) 44.82p +3.20%BHP Billiton (BLT) 2,644.50p +2.28%Cairn Energy (CNE) 454.70p +2.16%GKN (GKN) 206.10p +1.83%Capital Shopping Centres Group (CSCG) 392.00p +1.50%Essar Energy (ESSR) 474.80p +1.37%Resolution Ltd.
