CRCL stock is declining approximately 19%, with the direct trigger being expectations of restrictions on stablecoin yield mechanisms in the CLARITY Act. This requires examining the stablecoin business model itself.

The core profit structure of stablecoins is currently not complicated. Essentially, it involves deploying user-deposited fiat assets into low-risk assets like short-term US Treasury bonds to capture interest rate spreads.

Issuers like Circle do not distribute this revenue to users but retain it as company income, which has been the primary profit source for USDC over the long term.

A key market expectation previously was that if regulatory approval were granted, stablecoins could gradually introduce deposit-like attributes—for example, distributing interest to token holders or enabling USDC itself to generate yield through some mechanism. This would upgrade stablecoins from a payment tool into a hybrid form combining digital cash with yield-bearing assets, significantly enhancing demand stickiness and growth ceiling.

However, the CLARITY Act signals that stablecoin issuers cannot directly pay interest on balances; they can only provide rewards based on usage behaviors, such as transaction rebates or ecosystem partnership incentives.

This essentially cuts off the "hold-to-earn" pathway, positioning stablecoins closer to payment mediums rather than store-of-value assets.

This restriction creates three layers of impact.

First layer: user behavior

Without yield, users are more inclined to treat stablecoins as transit tools rather than long-term holdings. Funds flow into the stablecoin ecosystem only when transactions or transfers are needed, reducing capital sedimentation.

Second layer: competitive structure

Compared to money market funds, bank deposits, or even on-chain yield assets, stablecoins without yield become significantly less attractive in asset allocation decisions. Especially in a relatively high-rate environment, opportunity costs escalate.

Third layer: valuation logic

Much of the prior optimism on CRCL stemmed from the combination of "continuous USDC expansion + amplified interest spread income + potential interest distribution driving demand." If the last element is clearly restricted by regulation, the growth narrative compresses back to "payment and settlement infrastructure," requiring valuation repricing.

This also explains why market reaction has been so swift. Once stablecoins cannot evolve into "yield-bearing assets," their network effects and capital retention capacity become constrained, and long-term growth trajectory declines—not merely short-term profitability changes.

However, it's important to recognize this doesn't mean stablecoins lack development potential. Payment, cross-border settlement, and on-chain financial infrastructure remain massive markets, just with a pathway tilted toward "thin-margin, scale-driven businesses" rather than "high-stickiness, high-profit banking-like models."

This decline reflects not a single policy shock, but market repricing of stablecoins' ultimate form—from "potentially becoming part of a digital US dollar deposit system" back to a more conservative positioning as "efficient payment and clearing tools."
