Coinbase CEO Brian Armstrong Challenges Banks as Stablecoin Rewards Fight Grows

Coinbase CEO Defends USDC Rewards

Coinbase CEO Brian Armstrong is pushing back against the idea that crypto platforms offering stablecoin rewards should face the same capital and liquidity rules as banks.

In a Sept. 19 interview with Money Rehab, Armstrong argued that USDC rewards largely pass through part of the economic return generated by the assets backing the stablecoin, including short-term U.S. Treasuries.

“If you want to hold a stablecoin, you could actually earn reward,” Armstrong said. “Why shouldn’t consumers be able to benefit from that?”

The distinction matters because stablecoin rewards have emerged as a major battleground in Washington, with banks warning that higher-paying digital dollars could pull deposits from the traditional financial system.

Armstrong Says Stablecoins Are Not Bank Deposits

Armstrong drew a sharp line between USDC rewards and deposit interest.

“We’re not engaging in fractional reserve lending,” he said. “That’s what you need a bank license for.”

The GENIUS Act, signed into law in July 2025, requires permitted payment stablecoin issuers to maintain at least one-to-one reserves using eligible liquid assets. The law also prohibits issuers themselves from paying interest or yield, while leaving debate around rewards provided by exchanges and other third parties.

Armstrong said Coinbase is not a stablecoin issuer—USDC is issued by Circle, a close partner of the exchange—and argued that applying bank-style rules to the company would ignore those structural differences.

His broader message was simple: bank regulation reflects risks created by lending deposits, while fully reserved stablecoins operate differently.

Banks Warn Rewards Could Pull Deposits Away

Banking groups strongly dispute the idea that the issue is merely about protecting incumbents. The American Bankers Association and other groups argued that rewards tied to stablecoin balances could function like deposit interest and encourage money to leave community banks, seeking tighter restrictions on such programs.

Armstrong described that campaign as an effort by some large banks to limit competition.

“I think mainly the reason is competition,” he said. “They just didn’t want to have to compete with stablecoins that were paying these higher rates.”

The White House Council of Economic Advisers has also weighed in. Its analysis estimated that prohibiting stablecoin yield would increase total bank lending by only about $2.1 billion, while imposing an estimated $800 million annual welfare cost. Banking groups have challenged assumptions behind that analysis.

Stablecoin Rewards Remain a Washington Flashpoint

Armstrong said revisions to the CLARITY Act had addressed Coinbase’s earlier concerns around stablecoin rewards. Yet the legislation remains unresolved. On Sept. 15, the Senate rejected cloture on the motion to proceed with the bill by 49-50, short of the 60 votes required.

That leaves the underlying dispute very much alive.

For Coinbase, rewards can make digital dollars more attractive to consumers. For banks, similar programs could turn stablecoins into direct competitors for deposits.

The debate is no longer simply about crypto regulation. It is becoming a fight over who gets to earn, distribute, and ultimately capture the economics of the digital dollar.
