Investors are holding their breath ahead of today's torrent of economic data and events as they await firm direction following yesterday's quieter session. City sources predict the FTSE 100 will open around five points higher than yesterday's close of 6,816.37.The main release today is the monthly US non-farm payrolls report, which may have a significant impact on investors' interest rate expectations. Also on the cards are the latest ISM services sector figures, weekly jobless claims data and international trade numbers. Here in the UK, the most recent service sector purchasing managers' index is due out, which is particularly important as the sector is the largest component of UK gross domestic product (GDP). As noted by Jameel Ahmad, Chief Market Analyst at FXTM, "only last week, Bank of England Governor Carney stated that a potential interest rate hike would be economic data driven, while hinting that a UK unemployment rate below 6% might influence the decision".In addition to this raft of data, the European Central Bank (ECB) will hold its monetary policy meeting, marking another important event for markets today.CMC Markets' Michael Hewson said: "With the US off on Friday for the Independence Day holiday we have a host of event risk to navigate around today [...] Any volatility is likely to come from either the US employment report or the ECB press conference, with the rest of the data likely to be 'market noise'. "That doesn't mean that the data is unimportant, far from it, but from a policy point of view it's not likely to have a lasting effect."
