CoinGecko data show tether's market capitalization has increased by over 20% to $80 billion this year – with the valuation surging by 12% in the past four weeks alone.
The rise means tether's market cap is now just $3 billion short of the record high of $83 billion reached in May of last year.
Markus Thielen, head of research and strategy at crypto services provider Matrixport, said tether's valuation had been driven higher by "aggressive minting and issuance" on the Tron Network, which has a greater presence in mainland China compared to Ethereum and a greater focus on the movement on money.
Per data tracked by Matrixport, tether issued on Tron accounts for more than half of the stablecoin's current market value.
While tether's market capitalization has surged alongside bitcoin's (BTC) price rally, the market capitalization of Circle's USDC stablecoin, the world's second-largest dollar-pegged coin, has dropped by 27% to $32.5 billion. Investors began fleeing USDC last month after Circle revealed holding $3.3 billion with failed Silicon Valley Bank (SVB).
The market value of Paxos' centralized, dollar-pegged stablecoin BUSD has also declined by 58% to $7 billion this year. In February, the New York Department of Financial Services ordered Paxos Trust Company to cease minting BUSD. Paxos, in response, stopped minting new tokens while promising to process redemptions till February 2024.
According to Matrixport, some USDC holders likely diversified into tether and bitcoin.
"When news about unlimited support for bank deposits made the rounds, bitcoin prices exploded from $20,000 to $28,000 within a matter of days," said Thielen in a note to clients on Thursday. "But it would appear that holders of USDC either converted their Circle stablecoin into Tether's USDT or that they simply sold $10 billion of USDC and bought bitcoin instead."
