'Stablecoin' Google searches down 54% as supply growth stalls after 2025 boom

Google search volume for "stablecoins" fell to 31 in June so far, down from 98 in May and its highest-ever reading of 100 in August 2025.

And while June is not yet over and the current reading reflects only a partial month, annualizing it to a full month yields a figure near 45, implying a 54% month-over-month decline.

The August 2025 search peak coincided with discussions of the passage of the GENIUS Act and a wave of issuer announcements from Stripe, Visa, Mastercard and several U.S. retail banks.

The decline in search volumes this month coincides with aggregate stablecoin supply having reversed its ten-month expansion.

At the beginning of June 2026, total aggregate stablecoin supply peaked at just under $300 billion, and in the three weeks since, it has declined slightly by $5 billion.

Total stablecoin supply is now up just a meager 0.23% year to date. In comparison, total stablecoin supply grew by 56% in 2024 and 46% in 2025.

Speaking of these periods, in 2024 and early 2025, search interest led stablecoin supply growth, as Google queries for "stablecoins" surged in August 2025 when supply was in its steepest issuance phase, and the search peak coincided with the strongest single-month supply addition of the cycle: $16 billion in August 2025.

The June 2026 print breaks that pattern because search is collapsing while supply is contracting, which is consistent with a fully-marginal retail audience that has already onboarded onto stablecoins. The "stablecoin moment" likely already happened in 2025, with the passage of the GENIUS Act, the Circle IPO, and a wave of bank-issued stablecoin announcements, fully discounted into supply, meaning there is no new retail cohort left to acquire at the same incremental cost. 

It will be worth watching the fourth quarter of 2026, when the GENIUS Act regulatory clock starts and the first window in which U.S. bank-issued stablecoins can compete for the same float that USDT and USDC currently dominate.
