Australia’s securities regulator wants to extend leverage limits and other retail investor safeguards to certain trading contracts settled in crypto.

On Monday, the Australian Securities and Investments Commission (ASIC) proposed expanding the rules for contracts for difference (CFDs), which let traders bet on price movements without owning the underlying asset.

The rules generally cover contracts settled in cash or by offsetting obligations between the parties. ASIC wants to add contracts settled by transferring digital assets, including those tracking non-crypto assets, provided they meet the other criteria for a CFD.

ASIC said that certain crypto futures and options with fixed expiration dates would remain outside the CFD rules.
