2136 GMT - A difficult week awaits the Reserve Bank of Australia. On Tuesday, its policy-setting board is widely expected to raise interest rates for a fifth time this year. That outcome is almost fully priced in, so markets will focus on the bank's new inflation forecasts and any guidance about additional rate increases. Economists aren't ruling out another hike in December or February. The RBA will be raising interest rates as data show house prices are falling at their fastest pace in more than 40 years. Meanwhile, there's scope for the war in the Middle East to ramp up.
