Stablecoins shrank by $10 billion — what that number actually tells a beginner

The total value of all stablecoins has fallen by roughly $10 billion since its May peak, including a $7.7 billion drop in June alone — the largest monthly dollar decline since the Terra-Luna collapse in 2022. In percentage terms, though, that is only about a 3% fall, small next to the 26% contraction of the last bear market.

Start with what a stablecoin is. It is a token designed to hold a fixed value, usually one US dollar, and it is the currency most crypto trades are priced in, as well as a growing tool for payments and settlement. Because so much activity is denominated in them, the total supply of stablecoins is watched as a rough gauge of how much cash is sitting on-chain, ready to buy.

This decline came mainly from the two giants. Tether's USDT slipped to about $184 billion from $190 billion in May, and Circle's USDC fell to around $73 billion from a March peak just under $80 billion. Paul Howard, a senior director at trading firm Wincent, called it a small pullback in what he sees as a long-term growth market, adding that short-term swings in liquidity are normal.

Context helps a beginner avoid panic. In 2022 the combined value of major stablecoins fell 26%; USDC dropped below $24 billion as its banking partner Silicon Valley Bank collapsed, and the implosion of the algorithmic stablecoin TerraUSD wiped out $18 billion on its own. This time is nothing like that.

There is also a shift underneath the headline. After the US GENIUS Act, newer regulated issuers have appeared: Global Dollar (USDG), issued by Paxos and backed by a group including Robinhood, has passed $3.2 billion, and Anchorage's USDGO, run with Hong Kong's OSL, has neared $900 million, even as USDT and USDC slip. The takeaway for a beginner is that “stablecoin” is not one single thing. Issuer, backing and regulation differ, and so does safety — TerraUSD was called stable too, and it wasn't.
