Coinbase has quietly rolled out a High Yield tier on its USDC lending product, offering an annual percentage yield of roughly 7.02%. This move comes just days after Robinhood launched its own 7% campaign on its Earn platform. The new Coinbase tier roughly doubles the 3.63% APY available on its standard Core tier.
Both products route user deposits through Morpho, a decentralized lending protocol that currently holds $7.11 billion in total value locked. Steakhouse Financial curates both vaults. But despite the similar headline rates, the two designs work quite differently under the hood, according to a breakdown from analyst account Pink Brains.
Robinhood’s 7% number blends several components. It includes borrower interest, a reserve yield from the stablecoin $USDG’s Treasury bill backing, zero vault fees, and a top-up campaign run through Merkl. That campaign pays the gap between the organic yield and a fixed 7% target. Pink Brains says comparable Steakhouse-curated vaults have been printing organic yield around “mid 3%.” That means roughly half of Robinhood’s advertised rate is a subsidy rather than native return.
Coinbase’s design takes a different path. Depositors’ funds are looped against Ethena’s USDe stablecoin up to the edge of perpetual futures funding rates. Then the yield gets topped up with $MORPHO token rewards instead of a fixed-target subsidy. That means Coinbase’s organic yield floats with funding markets rather than sitting under a ceiling. It also isn’t propped up to a guaranteed number. Pink Brains notes the blended rate “now drops to 4.44% including boosted reward in $MORPHO,” down from the 7% headline.
Subsidy Math and Campaign Length
The two subsidy mechanics point to different depositor experiences over time. Because Robinhood pays only the delta to its target, a depositor who joins six months in earns the same rate as one who joined on day one, Pink Brains notes. Coinbase’s incentive-plus-market-rate structure instead rewards early depositors more, since $MORPHO incentives dilute as the vault’s total value locked grows.
Campaign length also diverges. Robinhood has committed its subsidy to run for a year. The company is betting that organic yield climbs toward 7% as new borrower demand, including institutional credit and margin lending against tokenized stocks, arrives on the platform. Separately, analyst tomwanhh put Coinbase’s campaign window at running to mid-September, with an option to extend. Neither company has confirmed unofficial timeline on its own channels.
Both companies are chasing the same underlying float: stablecoin reserve income shared through distribution deals. Circle provides for Coinbase, and the Global Dollar Network provides for Robinhood’s $USDG. Whether either rate survives a full year without erosion depends on borrower demand neither company has locked in yet. Both platforms describe their advertised rates as estimates subject to change.
