Tether is no longer just a stablecoin issuer — it is rapidly turning into a sovereign-scale gold holder.
Over the final quarter of 2025, the company added roughly 27 metric tons of physical gold to its reserves, placing it among the largest buyers globally during the period. That followed a similarly aggressive accumulation pace in the previous quarter, when purchases were estimated at around 26 tons. By year-end, Tether’s total gold buying for 2025 reached an estimated 116 tons, a level that rivals — and in some cases exceeds — official-sector demand.
This surge in accumulation has unfolded alongside a historic rally in gold prices. Spot gold climbed 18% year-to-date after already posting a 64% gain in 2025, blasting through the $3,000, $4,000, and $5,000 per ounce milestones. At current prices, Tether’s gold holdings are valued at roughly $4.4 billion, making the company a meaningful source of marginal demand in an already tight market.
Unlike central banks, Tether’s buying spree is not tied to monetary policy or trade balances. Instead, the firm is deploying profits generated from backing its dollar-pegged stablecoin, $USDT. With about $187 billion in $USDT circulating, interest earned on reserve assets — primarily U.S. Treasury bills — has become a powerful engine for capital accumulation.
This has transformed Tether into a hybrid financial actor. As of the end of September, its reserve disclosures showed gold holdings worth $12.9 billion, equivalent to roughly 104 tons at the time. Even so, gold still represented only about 7% of $USDT’s total backing, with Treasuries continuing to dominate the reserve mix.
Gold also plays a central role in Tether’s tokenized bullion product, XAUT. The company now controls around 60% of the global gold-backed stablecoin market, which expanded from about $1.3 billion to more than $4 billion over the course of 2025. By December 31, Tether held over 520,000 fine troy ounces of gold to back XAUT on a strict one-to-one basis, with reserves stored in Swiss vaults meeting London Good Delivery standards.
Compared with official buyers, the scale is striking. Poland’s central bank — among the most active in the public sector — added 35 tons of gold in the fourth quarter, lifting its total reserves to about 550 tons. That a private crypto company is now operating in the same league underscores a broader shift in global demand dynamics.
As stablecoins grow, they are emerging as a parallel force in the gold market, increasingly competing with nation-states. The key issue is no longer how much gold Tether might buy next, but what it means when private issuers of digital dollars begin shaping their own version of monetary credibility — without the traditional safeguards that underpin central banking systems.
