S&P Downgrades Tether’s USDT Stability, Sparking Panic Among China’s Crypto Traders
Introduction: A Shockwave Through Crypto’s Core Infrastructure
On November 26, 2025, the cryptocurrency world was jolted by a significant development from a mainstream financial authority. S&P Global Ratings downgraded the stability score of Tether’s USDT stablecoin from ‘constrained’ to ‘weak,’ citing increased exposure to volatile assets like Bitcoin and insufficient reserve transparency. This move has sent ripples of anxiety through global markets, but the reaction has been particularly acute among one of the world's most significant crypto cohorts: traders in China. For over 20 million Chinese citizens who rely on USDT as a lifeline to access digital assets despite a comprehensive ban, the downgrade is not merely a headline but a potential threat to the very infrastructure of their financial activities. The event has ignited a firestorm of debate on Chinese social media, revealing a community torn between dismissive skepticism born of past resilience and genuine fears of a catastrophic market collapse.
S&P Flags Reserve Composition Concerns: The Anatomy of a Downgrade
The official report from S&P Global, released on Wednesday, provided a detailed and critical assessment of Tether’s reserve structure, leading directly to the stability score downgrade. The agency’s analysis pinpointed several key areas of concern that collectively contributed to the ‘weak’ rating.
Central to S&P’s argument was Tether’s growing allocation to Bitcoin. The report stated that Bitcoin now makes up 5.6% of the assets backing circulating USDT, a figure that exceeds the company’s previously stated buffer of 3.9%. This increased exposure to a famously volatile asset class introduces a higher degree of risk to the stability of the peg to the U.S. dollar.
The analysis extended beyond Bitcoin. According to Tether’s own Q1–Q3 2025 attestation reports, which S&P referenced, the company holds $9.9 billion in Bitcoin and an additional $12.9 billion in gold. When combined, these volatile assets account for approximately 13% of the total reserves backing $174.4 billion in liabilities (the circulating USDT). S&P’s report also highlighted exposure to other high-risk assets, including secured loans, corporate bonds, and precious metals.
A recurring theme in S&P’s critique was transparency. The agency noted “ongoing gaps in disclosure practices,” raising doubts about USDT’s long-term ability to maintain its 1-to-1 peg. It is crucial to note, however, that Tether’s transparency reports also show substantial holdings of highly liquid and stable assets. The same reports indicate US Treasury holdings of more than $113 billion, which account for the majority of its reserves against a total of $181.2 billion in reserves. Furthermore, Tether has reported generating over $10 billion in profit in the first three quarters of 2025 alone.
Chinese Traders React With Mixed Emotions: From Skepticism to Panic
The news of the downgrade triggered an immediate and intense reaction within Chinese crypto circles, where USDT is not just another token but the dominant medium of exchange. The response was far from monolithic, revealing a deep split in sentiment among traders.
On one side, veteran traders exhibited a sense of dismissive skepticism. This cohort pointed out that negative news about Tether has surfaced regularly over the years without leading to a collapse, often appearing near market lows. Their view underscores a prevailing belief that stability warnings have historically failed to materialize into tangible crises, fostering a degree of resilience—or complacency—within the community.
On the other side, many participants expressed significant concern and outright panic. The anxiety stems from USDT’s critical role as the core infrastructure for China’s thriving but banned crypto ecosystem. For these traders, any threat to USDT is a direct threat to their financial access and holdings. This sentiment was captured vividly in a post on Weibo, which quoted a user stating, “If this bomb goes off, the cryptocurrency market is completely finished!”
The debate also veered into competitive territory, with conspiracy theories emerging about coordinated attacks by stablecoin rivals like USD Coin (USDC). Some analysts and community members argued that these competitors stand to gain significantly from undermining USDT’s market dominance, especially as global regulatory scrutiny intensifies. Critics of Tether used the opportunity to promote alternatives like USDC, citing their stronger transparency and perceived regulatory compliance as safer long-term options.
Underground Market Faces Stability Test: USDT as an Indispensable Lifeline
To understand why the S&P downgrade resonated so powerfully in China, one must examine the unique structure of the country's crypto market. China began implementing comprehensive cryptocurrency bans in 2017, culminating in a 2021 edict that outlawed all crypto transactions and mining. Despite this stringent regulatory environment, data indicates that more than 20 million Chinese citizens held Bitcoin as of 2024.
This persistent activity is facilitated by a sophisticated underground economy. Traders utilize overseas exchanges, over-the-counter (OTC) platforms, and private peer-to-peer deals to bypass local restrictions. At the heart of this shadow financial system sits Tether’s USDT. It has emerged as an indispensable lifeline, enabling Chinese investors to convert their yuan into a dollar-linked digital token through informal channels.
Social media platforms like Weibo and WeChat continue to show robust and continuous interest in Bitcoin and crypto trading, with rapid growth observed in certain exchange communities. This entire network relies heavily on influencers and so-called “signal teachers” who guide users through the complex web of regulatory barriers.
The scale and informal nature of this activity explain the profound impact of the S&P announcement. Any meaningful disruption to USDT’s liquidity or peg could trigger a chain reaction across an ecosystem that operates without official recourse or protection. Chinese traders inherently face elevated risks due to the unregulated channels they depend on, making them exceptionally sensitive to any perceived weakness in their primary gateway asset.
Strategic Conclusion: Navigating Uncertainty in a Fragile Ecosystem
The downgrade of Tether’s USDT by S&P Global represents more than a critique of a single stablecoin; it is a stress test for one of cryptocurrency's most critical pillars. For the global market, it underscores the ongoing tension between the crypto industry's disruptive ethos and the traditional finance world's demands for transparency and stability.
For China’ underground trading community, however, the implications are far more immediate and personal. The event has laid bare the fragile foundation upon which millions rely to participate in the digital asset economy. The mixed reactions—from unwavering skepticism to dire panic—highlight a community grappling with its dependency on an asset now deemed ‘weak’ by a major rating agency.
Moving forward, market participants should monitor several key developments. First, Tether’s response and any subsequent changes to its reserve composition and disclosure practices will be critical in restoring—or further eroding—confidence. Second, the potential for market share shifts among stablecoins like USDC could accelerate if traders seek perceived safer havens. Finally, the reaction of Chinese regulators, who now face a potential vulnerability within their own banned but pervasive crypto market, remains an unpredictable variable.
While past warnings about Tether have not resulted in collapse, the formal involvement of an institution like S&P Global marks a new chapter in stablecoin scrutiny. For China's crypto traders and the world at large, the stability of USDT remains a linchpin for market confidence, making its future trajectory one of the most closely watched stories in finance.
