Stablecoins Poised for $2 Trillion Domination by 2028—US Treasury Drops Bombshell Report

The US Treasury just handed crypto bulls a golden ticket—stablecoins could eat a $2 trillion slice of global finance within four years. That’s more than some sovereign wealth funds. Let that sink in.

Behind the numbers: Tether’s shadow banking empire, Circle’s Washington charm offensive, and a whole lot of institutional money pretending they ‘never doubted’ crypto’s utility. Wink, wink.

Bonus jab: Wall Street’s still calling it a ‘fad’ while quietly building backdoors into every stablecoin project that survives the coming regulatory bloodbath. Classic.

But the report cautioned that yield-bearing stablecoins could rival traditional bank deposits. 

Stablecoin growth — Impact on BTC, crypto

Overall, the stablecoin sector, led by Tether’s USDT and Circle’s USDC, is the hottest crypto segment, drawing interest even from banks amid the U.S push for regulatory clarity. 

The sector’s market size is currently at $239 billion, per CoinMarketCap data. In April, stablecoin transaction volumes hit a record high of $1.82 trillion.

According to venture capital firm a16z, stablecoins are a ‘WhatsApp moment’ for money, citing growing use cases beyond crypto speculation like international transactions.  

“And organic, non-speculative uses appear to be growing, even as crypto trading volume fluctuates.”

Tracy Jin, COO of crypto exchange MEXC, shared a similar but slightly different outlook. Jin told AMBCrypto that the expected stablecoin growth could boost Bitcoin [BTC] prices. She said,

“Fiat inflows converted into Tether (USDT) and Circle (USDC) are steadily flowing into Bitcoin, remaining the primary driver behind its price growth this year. Right now, every additional billion in stablecoins tends to push the BTC price up by 8-10%.”

This could be true from a long-term perspective, since growth in the stablecoin market has been positively correlated with BTC price.

However, the USDT market grew from $137B to $148B ($11B) between January and April 2025. Over the same period, USDC surged from $43B to $62B (+$20B in growth). 

Over the same YTD (year-to-date) basis, BTC was only up 1.7% despite the massive growth in top stablecoins. 

Overall, stablecoin growth has the potential to impact BTC and the crypto market positively. However, the massive sector’s expansion could be due to other uses besides speculative trading, like cross-border payments.
