Crypto exchange giant Binance’s BUSD stablecoin has extended its recent declines, amid mismanagement issues involving the exchange’s pegged tokens that surfaced earlier this month, and other debacles.

BUSD’s circulating supply fell to $15.4 billion on Wednesday, paring down $1 billion over the past week and $2 billion in a month, according to cryptocurrency price tracker CoinGecko. The latest drop extended BUSD’s decline from $22 billion in early December when anxious users scrambled to withdraw funds from Binance after it botched a report about its digital asset reserves.

Earlier this month, blockchain research firm ChainArgos found that Binance-peg BUSD was not always fully backed by reserves during 2020 and 2021. Binance acknowledged the breach and said it has fixed them since then. This week, a Bloomberg report found that the exchange mixed customer funds with the collateral of Binance-peg tokens.
