Woofun AI reports that Federal Reserve Governor Christopher Waller integrated stablecoins into the central bank's dollar research agenda during the Fifth Conference on the International Roles of the U.S. Dollar held on June 22, 2026. This strategic pivot reframes stablecoins from mere crypto trading tools into a private layer operating atop public dollar infrastructure. Waller emphasized that distributed ledger technologies and tokenized assets are forging new channels for global dollar intermediation alongside traditional banking systems.

The Federal Reserve is now scrutinizing whether stablecoin expansion will broaden global dollar access or introduce systemic pressures via bank deposit shifts and liquidity risks. Data compiled by Woofun AI shows Tether (USDT) and USDC ranked among the five largest crypto assets by market capitalization on June 25. USDT commanded a market capitalization of nearly $186 billion, while USDC stood at nearly $73.8 billion.

Notably, Tether's 24-hour trading volume reached around $81 billion, surpassing Bitcoin's roughly $43 billion.

Circle described USDC as backed by highly liquid cash and cash-equivalent assets, with most reserves held in the Circle Reserve Fund. This fund is an SEC-registered government money market fund managed by BlackRock. A June BIS working paper revealed that dollar-backed stablecoin inflows can lower short-term Treasury bill yields, with effects intensifying during Treasury market stress. A 2026 Treasury Borrowing Advisory Committee presentation noted that major stablecoin issuers currently hold less than 1% of outstanding Treasuries.

Despite current low holdings, the committee suggested future expansion driven by offshore users could significantly increase demand for short-end Treasury issuance. On June 5, The Clearing House announced that major financial institutions are backing an on-chain commercial-bank-money initiative to facilitate tokenized deposit clearing and settlement. This effort aims to connect blockchain activity with RTP and CHIPS systems.

The Federal Reserve's current stance remains anchored in research and understanding rather than adopting a specific stablecoin model. This evolution signals a transition where stablecoin mechanics are treated as critical variables in national monetary policy rather than peripheral digital assets. The convergence of private token issuance and public debt markets marks a definitive shift in how central banks monitor dollar liquidity.
