London pre-open: Declines expected ahead of key US data

City sources predict the FTSE 100 will open about 35 points lower than yesterday's close of 6,498.78.

A surprise decision by the Swiss National Bank to remove a currency ceiling rocked financial markets worldwide on Thursday, causing stocks to plummet initially, though equities rallied strongly into the close as hopes for further stimulus measures in the Eurozone increased.

As for Friday’s session, the focus will be on US data with consumer-price inflation due out later on, along with industrial production figures and the University of Michigan consumer-confidence index.

Inflation will be closely watched and is expected to show that the annual rate of price rises slowed dramatically to just 0.7% in December from 1.3% the month before on the back of a recent slump in oil. Core inflation, which excludes food and energy, is expected to hold steady at 1.7%.

“We expect Fed to ignore the decline in headline inflation as long as the labour market continues to improve and core inflation and inflation expectations do not start to slide substantially,” said analysts at Danske Bank.
