The supply of the two largest stablecoins has declined over the past seven days, even as Congressional tailwinds and a steady drumbeat of institutional partnerships have pushed stablecoins to the forefront of policy discussions.
$USDC Circulating supply subsequently fell by 0.7% in the week, from $75.08 billion to about $74.6 billion, according to DefiLlama. tether’s $USDT It fell 0.1% over the same period, from $186.49 billion to about $186.3 billion.

floats and headings
Qualitative pipeline indicates bullishness. The House of Lords is considering the CLARITY Act, the framework for the GENIUS stablecoin is law, and the Bank of England published draft rules for systemic stablecoins this month. Mastercard has opened its card payment network to stablecoins across eight blockchains, and three of Japan’s megabanks have established a joint stablecoin council.
None of this is reflected in the net new issuance from the two assets that make up the bulk of the market. $USDC and $USDT Together, the two companies have approximately $261 billion in circulating supply, according to DefiLlama.
