London's reaction to the keenly awaited Italian bond auction bordered on indifference, but investors took heart from US business activity data. Propelled by Wall Street's tail-winds, Footsie finished on a high for the day. Italy sold €2.5bn worth of benchmark 10-year bonds at an interest rate of 6.98%, below the psychologically important 7% level, but hardly a level to prompt dancing in the streets. At a similar auction last month the interest rate was 7.56% indicating the perception of risk has lessened, although it remains extremely high.Italy also sold €2.5bn in three-year bonds at an interest rate of 5.62% compared to the 7.89% level seen in November.A final €2bn tranche of bonds due in 2018 and 2021 was also sold at floating rates.Business activity in the US has performed better than expected, with the Institute of Supply Management in Chicago revealing its business barometer index dropped 0.1 from 62.6 in November to 62.5 in December. Forecasters had been expecting a bigger drop.
