July 29 (Reuters) - London's FTSE 100 touched an intraday

record high on Wednesday, driven by a surge in oil stocks

following renewed conflict in the Middle East, while investors

awaited interest rate decisions from the Federal Reserve and the

Bank of England.

The blue-chip FTSE 100 index closed up 0.34% at

10,908.41 points. It made a new peak of 10,951.06 points earlier

in the session.

The midcap FTSE 250 inched down 0.03% to 23,996.81

points.

* Energy stocks jumped 2.9% as oil prices

rose nearly 7% as major airstrikes resumed in the

Middle East and dashed hopes for an imminent end to the

U.S.-Israeli war with Iran.

* The Federal Reserve is seen as more likely to leave

interest rates steady at 1800 GMT on Wednesday, though a growing

number of its policymakers fret openly about inflation and the

outcome is uncertain because of the no-guidance regime adopted

by U.S. central bank chief Kevin Warsh.

* The Bank of England is due to announce its decision on

Thursday, when it is widely expected to keep interest rates

steady.

* In a busy earnings day, Standard Chartered ( SCBFF )

climbed 2.8% after the bank posted a forecast-beating first-half

profit and lifted its full-year income target.

* Glencore ( GLCNF ) climbed 2.8% after the miner reported a

15% increase in first-half copper production, while Rio Tinto

gained 1.6% after reporting a 43% jump in half-year

underlying earnings.

* Greggs ( GGGSF ) rallied 18.5% to the top of the midcap

index after Britain's biggest fast-food chain reported a 20%

rise in first-half profit.

* Aberdeen Group ( SLFPF ) fell 4.5%, making it the worst

performer in the blue-chip index, after the asset manager

reported first-half net outflows of £3 billion ($4 billion).
