CommSec, the online trading platform of Commonwealth Bank of Australia, has implemented a temporary 'sell-only' restriction on several Australian crypto ETFs, according to Monochrome CEO Jeff Yew. This restriction affects ETFs with physical redemption features, including IBTC and IETH, which remain tradable through other brokers. Yew announced that he is in discussions with CommSec to clarify the operational framework and investor protection mechanisms of these ETFs, which are notable for their physical subscription and redemption capabilities—a rarity in the global crypto ETF market.
