LONDON, June 6 (Reuters) - Britain's blue chip index ticked up 0.1 percent by midday on Friday as commodity stocks tracked oil and metal prices higher but Royal Bank of Scotland <RBS.L> led banks down as its huge rights issue closed.
By 1037 GMT, the FTSE 100 <
> was up 7.1 points at 6,002.4, well off its day's high of 6,074.5 but still holding its grip on the psychological 6,000 mark. The UK benchmark index gained 0.4 percent on Thursday."A lot of mining stocks are higher this morning...that's really the key fundamental behind higher equities generally. But I don't think this position is sustainable," said Neil Parker, market strategist at Royal Bank of Scotland.
"The equity markets are probably going to have a rough time over the next few weeks as the speculation regarding a rate hike intensifies," Parker said, referring to the European Central Bank's comment on Thursday that it may raise interest rates as early as July.
All eyes are on the U.S. non-farm payroll data for May, due at 1230 GMT. A Reuters poll showed a median forecast of a decline of 58,000 jobs last month, compared with a contraction of 20,000 in April.
Among prominent losers, Royal Bank of Scotland shed 1.8 percent, giving up earlier gains, as the deadline for its rights issue expired. Traders cited market talk of a 95 percent take-up of the issue.
"Those who have speculated that the rights issue will be a success are taking their money off the table -- you never go broke on a profit," said David Buik of Cantor Index.
Elsewhere in the banking sector, Lloyds TSB <LLOY.L>, Alliance & Leicester <ALLL.L>, HSBC <HSBA.L>, Barclays <BARC.L> and Standard Chartered <STAN.L> slipped between 0.2 and 3.7 percent.
SLICK OILS, SHINING MINERS
Oil shares, however, tracked firmer crude prices <CLc1>, which headed back up towards $130 a barrel as the dollar weakened against the euro on signals the European Central Bank may raise interest rates this year.
BP <BP.L> gained 1.6 percent, Royal Dutch Shell <RDSa.L> advanced 2 percent, Cairn Energy <CNE.L> climbed 4 percent and gas producer BG Group <BG.L> put on 2.9 percent.
Stronger metal prices also boosted miners, with BHP Billiton <BLT.L>, Rio Tinto <RIO.L>, Anglo American <AAL.L>, Xstrata <XTA.L>, Kazakhmys <KAZ.L>, Lonmin <LMI.L> and Antofagasta <ANTO.L> all up between 0.7 and 2.9 percent.
"The interesting thing about this market is that the FTSE 100 has not really wanted to give up much ground below 6,000. Also, it is not been much prepared to go above 6,000. 6,000 seems to a comfortable trading level for it," said Mike Lenhoff, chief market strategist at Brewin Dolphin.
"If the non-farm payrolls are not worse than expected, if they come in like a lot of the American data -- better than expected -- then we obviously are going to go higher."
Scottish & Southern Energy <SSE.L> rose 3.7 percent, placing it among the top gainers on the index, after Morgan Stanley upgraded the stock to "overweight" from "equal weight".
Mobile phone retailer Carphone Warehouse <CPW.L> advanced 2.3 percent after Merrill Lynch added the stock to its "most preferred telecoms list".
British Airways <BAY.L> topped the losers' list, down 5.3 percent on stronger oil prices and after rising 11 percent in the previous three sessions. Cruise operator Carnival <CCL.L> was also hurt by firmer crude prices, down 1.9 percent.
Also on the downside, Standard Life <SL.L> lost 4.2 percent after Deutsche Bank downgraded the insurer to "sell" from "hold". (Additional reporting by Michael Taylor; Editing by David Cowell)
