The stablecoin market has shed about $16 billion in value over the past 10 weeks, reaching a six-month low and marking the first extended decline since 2022’s Terra collapse. After hitting a peak of roughly $316 billion in May 2026, the total market capitalization slipped to just under $310 billion by late July, a modest 3% drop but a notable shift after years of steady growth.

Market Numbers and Drivers

Tether (USDT), the largest stablecoin, lost around $6 billion, falling from $190 billion in May to about $184 billion. Circle’s USDC also declined, down from near $80 billion in March to roughly $74 billion by late July. Unlike the dramatic 26% wipeout during Terra’s crash, this reduction is gradual but sustained, signaling a subtle change in investor behavior.

The legislation behind this trend is the GENIUS Act, enacted in July 2025. It introduced a federal regulatory framework that classifies payment stablecoins strictly as payment tools, banning any yield generation on these tokens. Meanwhile, tokenized Treasury products surged to $16 billion in assets as investors chase on-chain US government debt yields. This development challenges stablecoins’ appeal as non-yielding places to park funds, pushing capital towards alternatives with better returns.

Market Usage and Investor Reaction

Interestingly, while stablecoin market caps contracted, transaction volumes hit record highs. June 2026 adjusted transaction volumes soared to $1.79 trillion, reflecting growing use of stablecoins for payments and transfers rather than holding. This divergence suggests stablecoins are becoming more transactional and less a vehicle for savings or capital retention.

For crypto traders, the shrinking supply in major stablecoins like USDT and USDC means less immediate liquidity on exchanges. Historically, smaller stablecoin reserves correspond with reduced buying power, potentially impacting market dynamics. Investors may need to weigh these liquidity shifts as tokenized Treasuries gain traction.
