Here are some charts I put together using global Morningstar data on all worldwide open-end funds, ETFs and Money Markets.
To better illustrate the change in values I have segmented the period prior to the Global Financial Crisis, the bottom of the Global Financial Crisis and Today.
Total worldwide fund assets have grown from about 15 Trillion prior to the Global Financial Crisis to over 30 Trillion today. Meanwhile, as the chart below illustrates, despite the never ending talk of mysterious "cash on the sidelines" the percentage of global fund assets in cash today is lower than prior to the Financial Crisis.
Food for thought.
