* FTSE 100 index gains 0.3 percent
* High oil prices help energy stocks
* Shire boosted by ongoing bid speculation
* United Utilities, Severn Trent trade ex-div
By Tricia Wright
LONDON, June 18 Britain's top equity index
advanced on Wednesday, with oil companies lifting the market due
to high crude prices in the wake of heavy fighting in Iraq,
OPEC's second-largest producer.
Oil firms such as Royal Dutch Shell and BG Group
rose 1.6 percent and 0.8 percent respectively, helping
the UK oil and gas index gain 1.2 percent, the top
sectoral performer in the FTSE 100 by some margin.
"The market is very closely watching the escalating violence
in Iraq, a major oil producer. In the short term, higher oil
prices may benefit some oil companies, but in the longer term,
if it continues, it will result in an oil shock," said Henk
Potts, equity strategist at Barclays.
"Clearly that would be an overall negative for the economy
as higher oil prices have the potential to hurt global growth
and raise input cost of companies."
Brent crude oil rose towards $114 a barrel as Sunni
militants pushed forwards in northern Iraq, hitting the
country's biggest refinery and stoking concerns about oil
exports as some firms pulled foreign workers out.
The FTSE 100 was up 21.75 points, or 0.3 percent, at
6,788.52 points by 1313 GMT. The index is up only 0.6 percent so
far this year, but trades just 2.4 percent below its record high
in late 1999.
Shire topped the blue-chip leader board, up 2.8
percent, as bid speculation continued to swirl around the
healthcare group. It had seen solid gains on Tuesday after
sources told Reuters it had hired investment bank Citi as
an adviser, expecting to receive takeover approaches.
In the broader market, investors avoided heavy bets ahead of
the Federal Reserve's two-day policy meeting. The U.S. central
bank is widely expected to cut another $10 billion from its
monthly bond purchases, while investors will be watching for any
comments on when the Fed would begin to raise interest rates and
its outlook for the economy.
Data released on Tuesday showed a surprisingly high reading
for U.S. inflation, which sparked speculation of a hawkish tilt
to the Fed's policy outlook.
Gains were also capped by a 2.8 percent and 2.4 percent fall
respectively in shares of United Utilities and Severn
Trent as the two companies traded without the attraction
of their latest dividend payouts.
