Tether Adds 27 Tons of Gold to Reserves in Fourth Quarter
Tether, the issuer of the world’s largest stablecoin, said it added about 27 metric tons of gold to its fund exposure in the fourth quarter of 2025, broadly in line with its estimated third-quarter purchases.
The accumulation comes amid a powerful rally in gold prices. Gold has risen 18% year-to-date after gaining 64% in 2025, breaking through multiple psychological milestones, including $3,000 per ounce in March, $4,000 in October and $5,000 on Monday. The surge has been driven by strong investment flows, central bank buying and retail demand as global geopolitical tensions persist.
Tether has emerged as a notable source of gold demand due to the pace at which it has expanded reserves backing its digital assets. The company issues the USDT stablecoin, which has about $187 billion worth of tokens in circulation, and the gold-backed XAUT token, valued at roughly $2.7 billion.
Each USDT token is designed to represent one U.S. dollar held in reserve, backed by assets such as U.S. Treasury bills and gold. Tether’s XAUT token is fully backed by physical gold. According to the company, it held 16.2 tons of gold to support XAUT at the end of December, accounting for about 60% of the global gold-backed stablecoin supply.
“We are operating at a scale that now places the Tether Gold Investment Fund alongside sovereign gold holders, and that carries real responsibility,” said Paolo Ardoino in a statement.
For comparison, Poland’s central bank, the most active reported buyer among central banks, increased its gold reserves by 35 tons in the fourth quarter to a total of 550 tons. Tether did not disclose the total amount of gold it holds in Switzerland across its products.
Tether’s most recent publicly available audit of USDT reserves showed gold holdings worth $12.9 billion as of the end of September, equivalent to about 104 tons at then-prevailing prices. Despite the increase, gold represented only around 7% of USDT reserves at that time, with U.S. Treasuries remaining the dominant asset.
