What to know:
- Coinbase One users earn 6.5% APY for one month on up to $500k USDC after adding $1k, atop base 4.1% / 4.5% for One members.
- Adds 7% via Base Morpho lending (up to 10.8% observed), up to 15% more staking rewards.
- With USDC supply over $73.6B, exchanges are bundling yields to compete with DeFi, raising questions.

Coinbase is pushing its subscription product further, giving Coinbase One members only a limited 6.5% APY on USDC balances up to $500,000 for a month, provided they add a minimum of $1,000 in new USDC.
Yield from promotion plus basic rewards
This is an added promotion, apart from the default rewards of 4.1% APY from regular USDC balances, which get increased to 4.5% for Coinbase One members, from a part of Coinbase’s marketing budget as a member-only loyalty programme.
They don’t mention it in onchain lending. Based on the website (Help Center), the promotion is individual and limited to time, so that short-term holders can take advantage of high earning potential even if they hold onto their deposits.

Deeper Yield Opportunities
Yield is going deeper as the platform introduces more options. Members who are interested can now lend their USDC through Base-integrated Morpho vaults that are curated by Steakhouse Financial and they are quoted around 7% APY at the moment and even reaching as high as 10.8% in the month of September 2025.
