Commsec CDIA

Have you been considering opening a CommSec account to trade shares and other securities? If so you might have come across the Commonwealth Direct Investment Account, abbreviated to CDIA.

Curious as to what a CDIA is, whether you need one, and what the benefits are? Read on.

What is a CDIA?

A CDIA functions like a transaction account, but with some key differences. You can use it to fund trades on CommSec, make regular transactions, and withdraw cash at an ATM.

The main benefit of a CDIA is the cheaper brokerage fees, which come down to $10 compared to the standard $29.95 for trades up to $1000. In addition, account balances of $500,000 or more earn interest at 0.1% p.a.

Pros & cons

Pros

  • Get reduced brokerage fees, saving up to $19.95 on each trade.
  • No ongoing fees so you can keep more of your money to trade with.
  • Earn interest if you have more than $500,000 in the account.
  • Free dividend direction with CommSec means that your dividends will be automatically paid into your account.

Cons

  • Another bank account to manage can be a hassle, but you will need a cash management account to fund your trades.
  • No interest earned if you are under the $500,000 minimum requirement, which could earn interest if saved elsewhere.
