The Australian ETF industry swelled by 3.7% in August, adding $1.5 billion, according to BetaShares.
Two thirds of these gains were delivered by asset appreciation, particularly in US shares, while a third ($550 million) came from new net inflows.
Of the $550 million net inflows for the month, more than $180 million came from international equities - continuing the trend which has persisted since the start of the year.
In the last 12 months, ETFs have grown by 34% or $10.6 billion.
Net outflows for the month were limited but came largely from investors pulling money out of Australian shares.
Yet the three biggest ETFs by market cap are all Australian equities: the SPDR S&P/ASX 200 ($3.7 billion), iShares S&P 500 ($3 billion), Vanguard Australian shares index ETF ($2.9 billion).
These Vanguard and iShares are also the most liquid with highest trading volumes, alongside Betashares Australian High Interest Cash ETF ($9.8 million).
In August, the highest creations were in the BetaShares Australia 200 ETF, which added $106 million these creations were possibly for an unnamed institutional investor who swelled the A200'S size by four times in one allocation in August, Financial Standard reported.
The highest redemptions were from the now $3.7 billion SPDR S&P/ASX 200 which saw redemptions worth $242 million.
There were no new product launches in the month, even though new launches were announced.
