The Cboe Volatility Index ( VIX ) is a real-time index that represents the market's expectations for the relative strength of near-term price changes of the S&P 500 index (SPX) .

The yield on the 10-year Treasury edged down 0. 05 percentage points to 1.44 per cent after the labour department reported that headline consumer price inflation accelerated 5 per cent in the 12 months to May — the largest year-on-year leap since 2008 and above the 4.7 per cent pace expected by economists.
