The Westpac-Melbourne Institute Consumer Sentiment Index fell unexpectedly by 2.2% in March to 99.1. A reading below 100 suggests pessimists outnumber optimists. The index had been improving of late so the latest number is seen as a bit of a setback. Sentiment in March was affected by political in-fighting and press coverage of possible changes to negative gearing, which in turn affected perceptions relating to personal finances.
