Strike introduces Bitcoin interest on cash balances
Strike launched an opt-in product for eligible U.S. customers to receive Bitcoin-denominated interest on cash, linking ordinary cash holdings to Bitcoin accumulation.
Strike announced Bitcoin Interest on Cash on October 6, 2026. The opt-in offering allowed eligible U.S. customers to earn interest in bitcoin while maintaining cash balances in the product.
The arrangement separated the asset held as principal from the asset received as a return. It offered a path to acquiring bitcoin without requiring a customer to convert the entire cash balance into BTC. That mechanism differs from lending existing bitcoin for a bitcoin return or from buying bitcoin outright.
The launch extended Strike's role beyond moving and exchanging money into the design of a cash-to-Bitcoin accumulation service. Eligibility, product terms and intermediary arrangements remained relevant to the customer's actual rights; the existence of the product did not make interest a native feature of holding bitcoin on-chain.
The October development was the launch of this specific offering, rather than a claim that Bitcoin itself had acquired an interest rate.
