By Michael Taylor
LONDON, Aug 15 (Reuters) - Britain's benchmark index edged up by midday on Friday as falling U.S. crude eased inflationary fears, while mining stocks weighed as metal prices headed south.
At 1003 GMT the FTSE 100 <
> advanced 21.2 points, or 0.4 percent at 5,518.6 to extend a 0.9 percent rise in the previous session.As U.S. crude <CLc1> prices slipped toward $112 a barrel, investors saw hope for a future interest rate cut from the Bank of England (BoE). The BoE raised hopes on Wednesday of an interest rate cut before year-end as it forecast the current record-breaking spike in inflation would reverse sharply as the economy grinds to a halt.
Banks led the upside, with Royal Bank of Scotland <RBS.L>, Barclays <BARC.L> and Lloyds TSB <LLOY.L> all trading positive as the sector accounted for over 9 positive index points.
Bradford & Bingley <BB.L> was up 0.9 percent after the close its 400 million pounds rights issue.
Retailers also rose as the inflationary threat weakened, with Next <NXT.L>, Kingfisher <KGF.L> and Carphone Warehouse <CPW.L> up 2.8-3.5 percent.
Heavyweight oil companies were mixed, with BP <BP.L> and Royal Dutch Shell <RDSa.L> up 0.3 and 0.7 percent respectively, while Tullow Oil <TLW.L> shed 0.6 percent.
"The equity market has taken heart from recent sharp falls in commodity prices," said Charles Stanley analysts in a note. "Nevertheless, the catalyst for these falls is the global economic slowdown and investors still need to take this on board in terms of the outlook for corporate earnings."
Sterling struck a 22-month low against the dollar, and the euro hit a six-month low against the U.S. currency.
Separately, in a note to clients, UBS analysts cut their FTSE 100 target for this year from 6,500 to 6,100, and set a target of 6,500 for 2009.
"The move is based on a top-down earnings growth forecast of 3.6 percent this year and a fall of 4.1 percent in 2009," the UBS analysts said.
The falling energy prices helped buoy British Airways <BAY.L>, FirstGroup <FGP.L> and Carnival <CCL.L>, traders said, with the travel companies rising 1.7-4.1 percent.
RSA Insurance Group <RSA.L> extended large gains from the previous session to rise 1.8 percent on vague press reports of a possible bid for the company. RSA declined to comment.
MINERS DOWN
On the downside, mining companies tracked falling metal prices <MCU3> <MZN3> with Antofagasta <ANTO.L>, Kazakhmys <KAZ.L>, Xstrata <XTA.L> and Anglo American <AAL.L> down 3.5-4.8 percent.
Vodafone <VOD.L> slipped 0.1 percent. The Financial Times said it was in talks with TDC <TDC.CO>, Denmark's leading telecommunications company, about buying part of its stake in Polkomtel, Poland's second-biggest mobile phone operator.
Among midcaps, British recruitment company Michael Page International <MPI.L> dipped 5.3 percent after it rejected an approach worth 1.3 billion pounds ($2.43 billion) from Swiss rival Adecco, saying it materially undervalued the company. [
]"As far as oil goes ... we've moved into a very new world and I don't think it's right to take a view that the oil price can be sustainable at below $100," said Howard Wheeldon, senior strategist at BGC Partners.
"We may be lower for a bit but you should still expect oil hovering closer -- and hopefully remaining -- to $120 and perhaps we can begin to live with that," he added.
Many European markets are closed or are suffering weaker trading volumes due to Assumption Day.
Traders hoped U.S. industrial production and capacity utilisation data for July and the Reuters/University of Michigan August preliminary consumer sentiment, due from 1315 GMT, would offer market direction as the session progresses. (Additional reporting by Dominic Lau; Editing by David Cowell)
