S&P/ASX 200 Index (ASX: XJO) consumer staples and healthcare were the only two sectors in the green last week.
The traditionally defensive sectors found favour during tough trading as investors braced for an interest rate hike on Tuesday.
The benchmark index fell 0.76% over the week to close at 8,665 points, after hitting a 15-week intraday low on Friday.
Traders are pricing in a 95% chance of the Reserve Bank (RBA) raising the cash rate to 4.6% this week.
Many experts expect another rate hike in November, which would be the fifth this calendar year.
Inflation remains above the RBA's 2% to 3% target, and last week the Governor, Michele Bullock, spoke of "materialising" upside risks.
On Friday, Trading Economics analysts said:
Markets are pricing a 95% chance of a 25-bp hike to 4.60% in September and a possible peak around 5.10%.
Meanwhile, uncertainty surrounding US-Iran negotiations kept oil prices elevated, fueling inflation concerns and a renewed selloff in global bond markets, while strong US business activity has increased bets for another Fed hike, boosting the greenback.
The US Federal Reserve raised interest rates for the first time in three years this month.
