London midday: Banks shrug off downgrades, but resources stocks drag

- Banks rise in spite of Moody's downgrade- Spanish banks need up to 62bn euros, says private audit- German business confidence falls to two-year lowBanks were making gains by midday as they shrugged off a sector-wide downgrade my Moody's, but the Footsie still remained in the red with oil and mining stocks providing a drag.Credit ratings agency Moody's has downgraded 15 major banks and financial instiutions, including the major lenders on Britain's High Street. Royal Bank of Scotland (RBS), Barclays, Lloyds and HSBC all got the downgrade treatment as the agency completed its review of the global banking sector. Barclays' rating was downgraded by two notches while the ratings of the others were ratcheted down by one level. Spanish banks will need €51-62bn euros in additional capital in a worst case scenario, according to the independent consultants Oliver Wyman and Roland Berger hired by the government to perform a new round of stress tests on its financial sector. Spain is expected to make a formal request for assistance from the EU some time over the next few days.However, analysts at Barclays Capital said that the situation in Spain will remain "unsettled" for the near future. "Some reactivation of secondary market purchases, coupled with further ECB actions (a rate cut of 50 basis points on July 5th and collateral easing), along with fundamental progress at the June 28-29th meeting, is essential for the unstable equilibrium not to deteriorate further or for some long-lasting improvement in Spanish bonds, in our view," they said.

The market was expecting a reading of 105.9.FTSE 100: Banks rise on rumours of easing liquidity buffersAfter slight fall early on, banking stocks Barclays, HSBC and RBS were making gains by lunchtime despite the Moody's downgrades. Nevertheless, RBS said it disagreed with the ratings change as it is "backward-looking and does not give adequate credit for the substantial improvements the group has made to its balance sheet, funding and risk profile." Lloyds, which was downgraded in a separate report to the others, was a high riser after saying Moody's has recognised "the substantial momentum we have made in de-risking our balance sheet and delivering on our strategy."It has been reported this morning that the Bank of England's financial policy committee (FPC) will announce a reduction of between 20-30% in banks' liquidity buffers to support lending.Despite the strength in the banking sector, heavyweight oil and mining stocks were registering steep losses with Petrofac, Vedanta, Amec and Tullow Oil among the worst performers.BHP Billiton was out of favour after giving the go-ahead to a massive investment on its coal operations in New South Wales, Australia.
