Interest rates are tradable assets just like bonds and stocks, but are not offered by nearly as many forex brokers as other common trading assets. Instead, this is a market dominated by professionals and large financial institutions. However, there are still a few Australian ASIC-regulated brokers that do offer them to their clients in the form of contracts-for-difference (CFD).
One thing that makes interest rate CFDs more complicated than other CFDs is that they come with fixed expiry dates. Just like the underlying interest rate futures contract, a position in the interest rate CFD also needs to be either closed out or rolled over into a new contract on or before the expiry date. It is therefore important that you make sure you understand how these instruments work before you trade them.
