Oct 2 (Reuters) -Australian shares inched lower on Wednesday as losses in banks outweighed gains in mining and energy stocks, while escalating tensions in the Middle East also curbed risk appetite globally.

The S&P/ASX 200 index .AXJO was down 0.3% to 8,185, as of 0026 GMT, extending losses to a second session. The Aussie dollar sat at $0.6882 AUD=D3, having slipped 0.5% overnight and away from a 19-month top of $0.6942.

Globally, stock markets declined as investors moved away from riskier assets, while oil futures surged due to supply concerns following Iran's missile attack on Israel.

Data released on Tuesday showed that Australian retail sales rebounded more than expected in August after a soft July.

The report could reinforce the Reserve Bank of Australia's (RBA) reluctance to cut interest rates anytime soon. Markets are implying just an 18% chance of a cut at the next RBA meeting on Nov. 5. 0#RBAWATCH
