Tether, the company behind the world's most widely used stablecoin USDT, has announced the termination of its Bitcoin mining operations in Uruguay. This decision comes in response to mounting energy expenses and increasing regulatory hurdles.
The shutdown brings an abrupt end to a $500 million investment campaign that began in 2023. Tether had already invested over $100 million in infrastructure and pledged an additional $50 million to local projects before deciding to withdraw. As a result, 30 out of 38 employees will lose their jobs as the company winds down its activities in the country.
After months of operational difficulties, Tether cited "unfavorable economic conditions" and a lack of competitive energy tariffs from local providers as the main reasons for the closure. The high cost of electricity, a critical factor for the energy-intensive process of crypto mining, made the venture financially unsustainable. Despite halting mining in Uruguay, Tether emphasized its ongoing commitment to long-term projects across Latin America.
Uruguay's Ministry of Labor confirmed that Tether had formally notified authorities about the closure and the resulting layoffs. Earlier, Tether had denied rumors of its exit, even as it reportedly faced a $4.8 million debt dispute with the state-owned utility company UTE. The company had initially promoted its Uruguayan operations as a model for sustainable Bitcoin mining, leveraging the country's renewable energy resources.
The collapse of Tether's Uruguay project highlights the risks associated with large-scale crypto mining in regions where energy prices are volatile. Tether had planned to construct three data centers and a 300-megawatt renewable energy facility, but economic obstacles proved too great. This move mirrors a broader industry shift, with miners increasingly relocating to areas like Paraguay and Texas, where electricity is more affordable. Tether has also announced new mining projects in Paraguay and El Salvador, each expected to have capacities between 40 and 70 megawatts.
The closure in Uruguay comes as Tether faces heightened regulatory scrutiny. S&P Global Ratings recently downgraded USDT's stability rating to "weak," pointing to the company's growing exposure to high-risk assets such as Bitcoin, which now makes up 5.6% of USDT's reserves. Experts warn that further declines in Bitcoin's value, coupled with losses in other volatile assets, could leave the stablecoin undercollateralized.
Tether's retreat from Uruguay underscores the importance of stable energy costs, clear regulatory policies, and secure long-term tariff agreements for the success of large-scale mining operations. While Tether remains optimistic about Bitcoin's future, its experience in Uruguay serves as a warning to others in the industry about the challenges of balancing profitability with operational risks.
