Coinbase CEO Says Deposit Lending Distinguishes Banks From Stablecoins
Brian Armstrong said Coinbase is not engaging in fractional-reserve lending as U.S. policymakers debate whether stablecoin rewards should face bank-style restrictions.
Coinbase CEO Brian Armstrong said Coinbase is not engaging in fractional-reserve lending, highlighting what he described as a key difference between banks and fully reserved stablecoins as U.S. policymakers debate restrictions on stablecoin rewards.
Armstrong made the comments during a Sept. 18, 2026, episode of Money Rehab with Nicole Lapin. He said banks can lend customer deposits, while reserves backing fully reserved stablecoins are not used for fractional-reserve lending.
The distinction centers on how customer funds and reserve assets are used. Banks can lend deposits, while fully reserved stablecoins are structured around assets intended to support redemption at a value matching the tokens in circulation.
The GENIUS Act became law July 18, 2025, establishing a federal framework for payment stablecoins. The law requires permitted issuers to maintain eligible reserve assets equal to at least the value of their outstanding payment stablecoins.
The law also bars payment stablecoin issuers from directly paying holders interest or yield solely for holding, using or retaining the tokens. It does not settle whether rewards offered by exchanges or other intermediaries should be treated the same way as interest paid on bank deposits.
That question is central to the policy debate over stablecoin rewards. A program offered by an intermediary could provide an economic benefit to users even when the underlying stablecoin issuer is subject to reserve and payment restrictions.
Armstrong’s comments frame the issue around the difference between lending funded by bank deposits and stablecoins backed by eligible reserve assets. The GENIUS Act’s reserve and payment provisions remain the governing framework for permitted payment stablecoin issuers.
