Coinbase will cease offering USDC deposit rewards to non-subscribers starting December 15. Currently, the exchange provides annual rewards of 2% to 3.5% to eligible USDC holders. After the change, only Coinbase One subscribers will receive the 3.5% rate, while non-paying users will no longer earn rewards. This decision follows the US Federal Reserve's recent 0.25% rate cut, the third reduction this year, prompting Coinbase to adjust its USDC rewards in the US and UK. The rewards program, funded by Coinbase, is designed to incentivize users to maintain USDC holdings on the platform.
