Moody's warns stablecoins could erode bank deposits

TLDR

Moodys says stablecoins are only a limited near?term threat to banks, but could gradually pull deposits away as they grow and start paying yield.

1. Moodys flags that stablecoins and tokenized real?world assets (RWAs) could, over time, drive bank deposit outflows and shrink lending capacity, even though todays impact is limited.
2. The core concern is yield: high?interest, fully reserved stablecoins could compete with bank deposits and money market funds, especially if they become widely used in payments and savings.
3. The outcome now hinges on regulation, including the US CLARITY Act stablecoin bill, where banks, the White House, and the crypto industry are fighting over how much yield stablecoins can pay.

Deep Dive

1. What Moodys Actually Said

Moodys analyst Abhi Srivastava argues that stablecoins currently pose a limited disruption risk to US banks because adoption is still constrained and US rules block yield?bearing stablecoins from mainstream use Moodys analysis.

Stablecoin market cap is already over $300 billion, and their role in cross?border payments and onchain finance is growing, but Moodys notes that existing US payment rails are already fast and cheap, which reduces short?term threat.

However, Srivastava warns that as stablecoins and tokenized RWAs scale, banks could face more competition for funding, with potential deposit outflows that reduce their capacity to extend loans.

2. How Stablecoins Could Erode Deposits

Fully reserved, liquid, and high?yield stablecoins can look like a safer, more convenient alternative to bank deposits or money market funds, especially if they plug directly into DeFi and global payments.

Banking groups warn that yield on payment stablecoins could incentivize households and corporates to shift large balances out of banks, particularly from smaller regional institutions that depend heavily on deposits. One lobbying script cited by US bank groups explicitly pushes for an airtight prohibition on stablecoin rewards to prevent deposit flight bank lobbying coverage.

The White House Council of Economic Advisers counters that even generous stablecoin yields would likely displace only a tiny share of bank lending, estimating roughly 0.02 percent of total loans at risk, which suggests the nightmare scenarios from banks may be overstated.

3. Regulation And What To Watch

The CLARITY Act stablecoin bill has stalled partly because of this yield debate, with banks pushing for a near?total ban and the White House urging them to move on from blocking innovation in yield?bearing stablecoins White House stance.

Moodys sees regulatory choices as key for banks future funding mix. Strict caps on stablecoin rewards would protect deposits, while more permissive rules could accelerate the migration of cash into tokenized dollars and RWAs.

For crypto users, clearer rules could unlock safer, more mainstream stablecoin products but may limit headline yields if regulators prioritise bank stability.

Conclusion

Moodys is not predicting an immediate banking crisis from stablecoins. It is signaling that as dollar?pegged tokens and RWAs mature, they could quietly chip away at traditional deposits, especially if regulators permit meaningful yield. The main variables to watch are US and global stablecoin rules, how much yield they allow, and whether banks respond by integrating tokenized money rather than fighting it.
