Macquarie Group has been ranked the world’s largest infrastructure manager by Willis Towers Watson, with assets under management of just over US$95 billion.
Direct infrastructure manager Macquarie Group has been ranked as the largest alternatives manager in Willis Towers Watson's 2016 Global Alternatives Survey, with US$95.04 billion in AUM.
US manager Blackstone's private equity business was second in the ranking, with US$94.3 billion in AUM, while Blackstone's direct real estate business was rated third, with US$93.9 billion.
The next highest Australian alternatives manager was IFM Investors' direct infrastructure funds (at US$22.39 billion) followed by AMP Capital's direct real estate division (US$17.86 billion).
Overall, total assets managed by the top 100 alternative investment managers as determined by Willis Towers Watson reached US$3.6 trillion, up 3 per cent on the previous year.
Total global alternative AUM now stands at US$6.2 trillion, according to the survey.
Real estate managers took the largest share of assets (34 per cent), followed by hedge funds (21 per cent) and private equity fund managers (18 per cent).
Willis Towers Watson senior investment consultant Nick Kelly said institutional investors continue to focus on diversity, but not at "all costs".
"While inflows into alternative assets continue apace, investors have become more mindful of alignment of interests and getting value for money," Mr Kelly said.
"This has contributed to a further blurring between individual ‘asset classes’, as investors increase their focus on underlying return drivers with the ultimate objective of achieving true diversity and making their portfolios more robust in the face of the increasingly volatile and uncertain macroeconomic environment," he said.
