Federal Reserve Governor Stephen Miran argued that stablecoins’ potential multi-trillion-dollar growth over the next five years will help push down interest rates.

A growing demand for US dollar-tied crypto stablecoins could help push down the interest rate, says US Federal Reserve Governor Stephen Miran.

The Donald Trump-appointed Miran told the BCVC summit in New York on Friday that the dollar-pegged crypto tokens could be “putting downward pressure” on the neutral rate, or r-star, that doesn’t stimulate or impede the economy.

If the neutral rate drops, then the central bank would also react by dropping its interest rate, he said.

The total current market cap of all stablecoins sits at $310.7 million according to CoinGecko data, and Miran suggested that Fed research found the market could grow to up to $3 trillion in value in the next five years.

“My thesis is that stablecoins are already increasing demand for US Treasury bills and other dollar-denominated liquid assets by purchasers outside the United States and that this demand will continue growing,” Miran said.

“Stablecoins may become a multitrillion-dollar elephant in the room for central bankers.”

Organizations, including the International Monetary Fund, have warned that stablecoins pose a threat to traditional financial assets and services, as they could potentially compete for customers. US banking groups have also urged Congress to tighten oversight of stablecoins with yield, arguing they could attract would-be bank users.

Regulation to pave the way 

During his speech, Miran praised the GENIUS Act for setting out clear guidelines and consumer protections, as he indicated that the regulatory framework will play a key role in spurring broader adoption of stablecoins. 

“While I tend to view new regulations skeptically, I’m greatly encouraged by the GENIUS Act. This regulatory apparatus for stablecoins establishes a level of legitimacy and accountability congruent with holding traditional dollar assets,” he said, adding: 

“For the purposes of monetary policy, the most important aspect of the GENIUS Act is that it requires U.S.-domiciled issuers to maintain reserves backed on at least a one-to-one basis in safe and liquid US dollar–denominated assets.”
