Volatility is set to return to global sharemarkets this week starting with the ASX, which is bracing for inflation data that could cement an interest rate increase from the Reserve Bank just as investors wait nervously on the next moves from other major central banks.

Futures point to a strong start on Monday for the local bourse with the S&P/ASX 200 set to open up 0.8 per cent following a solid rebound on Wall Street after economists bolstered bets that the US Federal Reserve is on track to lower interest rates by September.
