Bright start predicted
The FTSE 100 is set to open 60 points higher, helped by a pullback in global bond yields.
The yield on the 30-year US Treasury slipped to around 5.56% after touching 5.62% on Tuesday, its highest level since 2002.
Asian markets were mixed as investors waited for US inflation figures later today.
Japan led the way, with the Nikkei 225 up 1.5% as chip stocks rallied and SoftBank Group jumped 6%.
Hong Kong's Hang Seng slipped 0.3% and South Korea's KOSPI fell 0.4%.
In Australia, inflation rose to 4% in August, a day after the central bank lifted interest rates to a 15-year high of 4.6%.
Brent crude steadied at around $103 a barrel after a sharp fall on Tuesday.
The main event is the August personal consumption expenditures (PCE) price index, the Federal Reserve's preferred inflation measure.
Nobody expects it to show inflation anywhere near the Fed's 2% target; the only question is how far off it will be.
