What happened to Tether’s USDT stablecoin?

Tether’s USDT added more than $5 billion in supply over the past month. That lifted USDT’s total supply to about $189.7 billion, strengthening its lead in the stablecoin market.

Why does Tether’s USDT growth matter for crypto investors?

USDT’s growth shows that crypto investors still favour large, liquid stablecoins during uncertain market conditions. It also suggests traders are moving funds into stablecoins they see as safer and easier to use.

What happened to rival stablecoins like USDC, PYUSD, and USDe?

Circle’s USDC, PayPal’s PYUSD, and Ethena’s USDe reportedly lost a combined $4.2 billion in supply. This shows capital is shifting away from some rivals while Tether gains more market share.

Is new money entering the stablecoin market?

The wider stablecoin market grew by only 0.3%, so the article suggests there is little fresh money entering crypto through stablecoins. Most of the move appears to be investors rotating from rival stablecoins into USDT.

Why is Ethena’s USDe under pressure?

Ethena’s USDe has fallen nearly 34% since October 2025. Its decline raises concerns about synthetic, algorithmic, or hybrid stablecoin models when investors become more cautious.

Tether strengthens grip as stablecoin rivals lose ground

Written by Heidi Cuthbert Published May. 21 2026

Tether has tightened its hold on the stablecoin market after USDT added more than $5 billion in supply over the past month.

The rise lifted USDT’s total supply to about $189.7 billion, reinforcing its position as the largest stablecoin in global crypto trading.

The increase came as several rival stablecoins faced heavy outflows during a more cautious phase for digital asset investors.

Circle’s USDC, PayPal’s PYUSD, and Ethena’s USDe reportedly lost a combined $4.2 billion in supply over the same period.

The wider stablecoin market grew by only 0.3%, suggesting investors shifted capital between stablecoins instead of adding fresh funds to crypto.

Market behaviour now points to stronger demand for liquidity, scale, and perceived safety during periods of uncertainty.

USDT remains widely used across crypto exchanges, trading pairs, cross-border payments, and platform liquidity reserves.

Ethena’s USDe has faced sharper pressure, with the synthetic stablecoin down nearly 34% since October 2025.

Its decline has raised fresh questions about algorithmic and hybrid stablecoin models during risk-off market conditions.

USDT and USDC now account for around 93% of the global stablecoin market, showing how concentrated the sector has become.

Tether’s gains also come as US lawmakers continue discussions around the GENIUS Act and broader stablecoin rules.

Regulatory uncertainty has pushed some investors away from smaller or more experimental stablecoin projects.

DeFi protocols may also feel the impact if stablecoins such as USDe and PYUSD continue losing liquidity.

Some lending, collateral, and yield strategies depend on these assets, which means lower supply could affect borrowing rates and market depth.

Europe is also watching the dollar-backed stablecoin boom more closely as US-linked assets dominate the sector.

The Qivalis project, supported by 37 European banks, reflects Europe’s push to build a stronger regional alternative.

Nearly 98% of global stablecoins remain backed by the US dollar, making the market a growing issue for monetary competition.

Stablecoins are now moving beyond crypto trading and becoming tools for payments, treasury management, and financial influence.

Tether’s latest growth shows that investors still favour the biggest and most liquid stablecoin when market nerves rise.
