How does your trading platform manage your cash?
It might look like you simply deposit cash into your trading platform account, and it's held there for you to trade or withdraw as you please. But some platforms are investing and managing that cash in ways you may be entirely unaware of.
We want to explain here the ways platforms can do this, and why it's important to be aware, as it may mean your cash is at greater risk and cannot be withdrawn as easily as you expect.
In recent years, many new-gen share trading platforms have introduced facilities designed to pay a return on uninvested cash. These are often described using familiar terms such as cash management, cash plus, or at-call.
At a glance, these products can appear similar to a cash account. But when you read the fine print, you may find that some of them are doing far more than simply holding cash.
Trust accounts: the usual approach
The conventional approach is to hold client cash in trust accounts at authorised banks, in line with section 981B of the Corporations Act. In simple terms, this means your money is:
held on trust for your benefit
kept separate from the platform’s own operating funds
placed in accounts with regulated Australian banks
subject to rigorous conduct, regulatory and operational requirements as set out in s981 of the Corporations Act, and Part 7.8 of the Corporations Regulations.
When using such trust accounts, the trading platform’s role is primarily to safeguard and administer client money, not invest it. Any interest earned comes from the bank itself, rather than from market investments.
Managed investments: the unusual approach
But some trading platforms don't do this. Rather, they pool your cash into a managed investment scheme. This could be offered under a 'client money investing agreement' between the client and the platform, or offered in its own right as a 'money market fund'. The latter option, while often similarly presented as 'at-call', 'low volatility' and suitable for everyday investors, are legally and structurally different from basic deposit products. They are registered managed funds and, like any other managed funds, are exposed to risk of capital loss and liquidity constraints.
In this arrangement, the trading platform's role is a 'fund manager' that manages your investment with the primary objective of seeking investment returns. Clients who opt for this arrangement are no longer holding 'cash', but 'units in a managed investment scheme'.
These details can appear deep in your trading platform's disclosure statement of retail 'cash' or 'money market funds'. It's important that trading platform users understand these features as they are not traditional cash deposits.
Take these four steps to understand how your trading platform is managing your cash.
1. Start with the PDS, not the headline rate
A useful first step is to look past the advertised return and ask a simple question: Is my money being held, or is it being invested?
In some cases, the answer is 'invested', and the product disclosure statement may permit strategies that go well beyond what many people associate with a money market fund. The conventional approach to hold client money in a bank account, on the other hand, does not require a PDS as it is already the default option under Australian law.
Below are some examples of mandates that can appear in disclosure documents and are worth paying close attention to.
Private credit exposure: yield comes with liquidity trade-offs
Some cash or income funds allow investment in private credit.
Private credit typically involves lending to businesses or consumers outside of public bond markets. These loans are often not traded on exchanges and may need to be held to maturity.
Private credit has been widely discussed in financial news in early 2026, particularly during periods where some large funds faced liquidity pressure when many investors sought to withdraw at the same time.
Does this apply to your trading platform? Check the PDS to see:
whether the fund can invest in private or illiquid credit
the maximum percentage allowed
whether withdrawals can be delayed or suspended if assets cannot be sold.
Private credit can offer higher returns, but those returns exist partly because the money may not always be accessible on demand.
2. Leverage and derivatives add greater risk
Some funds marketed as 'low-risk' or 'cash-like' include the ability to:
borrow to increase exposure (leverage)
use derivatives such as swaps, futures or options
take short positions.
These tools are commonly used in sophisticated investment strategies such as hedge funds. They can increase returns – but they can also magnify losses and introduce counterparty risk.
For a product positioned as a 'money market' or 'cash alternative', it’s reasonable for investors to ask if a cash-style product needs leverage or complex derivatives at all.
The presence of these tools does not automatically make a product unsuitable, but it does change the risk profile in ways that are not obvious from a headline interest rate.
3. Dual-class structures: who gets the upside?
Some retail funds use a dual-class unit structure. This sometimes means investors hold one class of units with a stated target return, while another class, often held by the platform or related parties, absorbs excess returns above that target.
In some structures, this second class may also act as a buffer when target returns are not met – but it may be limited in size, redeemable, or not guaranteed to remain in place.
Check your platform's PDS to see:
whether your return is capped at a target rate
who receives returns above that target
whether another unit class benefits disproportionately in strong conditions
whether any return buffer is permanent or optional.
These arrangements are legal and disclosed, but they can be easily overlooked by retail investors who assume all fund returns flow equally.
How your cash is managed matters
None of the features described above are hidden by your platform. They're usually disclosed clearly in the PDS. But that doesn't mean it will be obvious to you.
Many investors don’t expect to find hedge-fund-style tools in what they thought was a cash product.
Headline descriptions can sound simpler than the underlying mandate.
Higher yield can mask higher complexity.
When a product behaves differently under stress than a bank account or trust account, understanding those differences upfront matters.
4. Make your own informed decision
We're not suggesting all managed funds are inappropriate, or that higher-yield products are 'bad'.
Rather, we remind trading platform customers to:
read their platform's cash facility PDS carefully
check whether the fund invests in private or illiquid assets
understand whether leverage or derivatives are permitted
look for structural features that affect who benefits from excess returns
consider how withdrawals are handled in stressed markets.
Different products are built for different purposes. What matters is knowing which one you’re using.
Is your platform managing your money how you want?
If a product is described as a money market or cash alternative, it’s reasonable to expect simplicity, liquidity and stability. When the PDS reveals strategies more commonly associated with credit funds or sophisticated investment vehicles, they're less likely to have the simplicty and liquidity customers often look for.
The best protection is to know how your trading platform manages your money and to decide ifr it aligns with your expectations.
